High quality iron oxide yellow was prepared from pyrite cinder of industrial solid waste.Copperas was(obtained) after adding mechanically activated pyrite into acidic leaching solution that was produced from the reaction of pyrite cinder with sulfuric acid.Needle-shape iron oxide yellow was prepared by putting ammonia water and(ferrous) sulfate solution in Fe~(2+) solution containing crystal seed of iron oxide yellow,and then oxidizing with air for 72 h.The optimal conditions of crystal seed preparation are 40% of mass concentration of copperas,0.25 of base ratio,0.25 m~3/h of air flow,29 ℃ of reaction temperature,10 h of oxidation time.The optimal conditions of oxide iron yellow preparation are 33% of seed ration,80-85 ℃ of reaction temperature,2.8-3.5 of pH value,0.25 mol/L of Fe~(2+),and 0.6 m~3/h of air flow.


The population of Indonesia in 2021 is about 273 million people. The increasing population is followed by an increase in food needs, including animal food. The area of land as a base of food production does not increase, even tends to decrease due to conversion, abrasion, and submerged seawater as a result of global warming and climate change, as well as the declining quality of natural resources. Animal protein consumption in Indonesia is very low and is expected to increase sharply as the income of the population continues to increase. Anticipating this, it is necessary to prepare a medium- and long-term farm development strategy in a sustainable manner by utilizing the availability of local resources. Exploring the genetic resources of livestock that are efficient in the use of feed, should also be able to utilize feed materials in the form of crop byproducts and agricultural industries. This policy should be supported by technological innovation and sustainable productivity and livestock production. Can save natural resources while reducing greenhouse gas emissions in order to realize the concept of green economy.


A 1×1 cm2 p-AlGaAs/p-GaAs/n-GaAs concentrator solar cell operating at high concentration ratios without forced cooling is described. The cell has a fairly large junction depth (the thickness of the p-GaAs layer) of 3 µm which reduces the sheet resistance of the surface layer and permits the use of a relatively crude contact grid pattern which is easily fabricated. The cell has its highest fill factor of 0.889 at 50–100 suns and its highest efficiency of 22.7% at 50–200 suns, and also maintains a practical efficiency of 17.6% even at 1025 suns without forced cooling.


In the Kakheti region of Georgia in the work of anti-hail system anti-hail rockets "Loza-2" of the production of Bulgaria from September 2018 are used. Some results of the calculations of the optimum areas of cloud seeding by the crystallizing reagent for more than 80 points of action located on the protected territory in Kakheti are given. The characteristics of the anti-hail rockets "Loza-2" and "Trayal D 6-B" are compared.


Opsoclonus-myoclonus syndrome is a distinct neuro- logic disorder characterized by opsoclonic eye move- ments, multifocal myoclonus, and ataxia, traditionally described as "dancing eyes, dancing feet." A presenting sign in 2% of children with neuroblastoma, it usually heralds a favorable prognosis for the tumor. Although opsoclonus-myoclonus syndrome usually presents at initial diagnosis or relapse, there are reports of delayed presentation, usually a few months after diagnosis. This report describes a patient with ganglioneuroblas- toma who developed recurrent symptoms of opsoclo- nus-myoclonus syndrome 9 years after completing treatment, without evidence of recurrent tumor. Be- lieved to be autoimmune in origin, opsoclonus-myoclo- nus syndrome frequently responds to immunomodula- tory therapies, such as steroids or intravenous immunoglobulin. This patient did not respond ade- quately to either agent, so plasmapheresis, a less com- monly used modality in opsoclonus-myoclonus syn- drome, was attempted. His symptoms resolved after he received therapy with a combination of plasmapheresis and steroids over a 1-year period. After being slowly weaned off all therapy, he has been symptom-free now for over 3 years. Armstrong MB, Robertson PL, Castle VP.

A kinetic model for the free-radical-initiated molecular weight degradation of polypropylene was further developed. The model has a single variable parameter, the initiator efficiency, f. Assumptions were detailed, new comparisons with experimental data presented, and model sensitivity to the value of f evaluated. The model was found to provide a good description of both molecular weight distribution and molecular weight average data from degradations carried out in a single-screw extruder at 200 and 220°C. Data at 0.04 wt% initiator feed concentration were fit and the resulting f value used to predict results at 0.01 wt% and 0.02 wt%. In accordance with observation, the model predicted that temperature would have no effect on the molecular weight of the extrudate because the comparatively long (≥ 2.8 min) residence time in the extruder permitted degradation reactions to go to completion. The model predictions were found to depend upon the change in molecular weight distribution rather than the absolute value of the distribution data. Predictions were therefore unaffected by concentration correction in size exclusion chromatography interpretation. The model was determined to have a low sensitivity to the value of f. Hence, f was estimated to only ± 25% and it is anticipated that attempts to use the model for comparing different initiators would be limited by this characteristic. Also, because the minimum residence time in the extruder was 2.8 min, the model has yet to be tested against data at times less than this value.


Vehicle Routing Problems (VRP) involve designing least-cost delivery routes to visit a geographically-dispersed set of customers. Over the past 60 years, this class of problems has been the subject of considerable work, summing up to thousands of articles. In 2017, we can reasonably say that the classical capacitated VRP (with only capacity constraints) is fairly well solved by metaheuristic techniques. Yet, the research on VRPs keeps on expanding even further, as a consequence of the increasing diversity of applications, which bring forth new difficult constraints, objectives, and combined decisions to account for customers needs, vehicle and network restrictions, and to better integrate VRP optimization in the decision chains. Moreover, with the advent of collaborative logistics, green initiatives, smart cities, multi-modal transport, in contexts where multiples stakeholders and conflicting objectives have to be considered jointly, or in the presence of dynamic problems with a short response time, the efficient resolution of these problems becomes even more critical. In this talk, we will review some of the most challenging and recent VRP variants, and examine the heuristic solution techniques which are developed to tackle them. We will study the close connections between the structure of the problem decision sets, and the associated solution methods, showing how modern heuristics can effectively perform a search in a reduced space, defined by fewer groups of decision variables. Finally, a key challenge is to progress towards unified solution methods, which are not tailored for one single problem, but instead designed to solve a wide collection of problem variants with different constraints and objectives. For this purpose, we expose some of the main principles of the Unified Hybrid Genetic Search (UHGS), which has been recently extended to obtain state-of-the-art results --in a single code base-- for more than 50 difficult variants of vehicle routing and arc routing problems.


The described clinical case presents 39-year-old patient with no clinically significant accompanying diseases. Since the beginning of October 2015, the patient has complained of fever, abdominal pain and generalized enlarged lymph nodes. Biopsy of axillary lymph node evidences Rosai-Dorfman-Destombes (RDD) disease. Treatment with corticosteroids has been started but with no clear influence on paraclinical activity and lymphadenomegaly. From the additionally made examinations, clinical laboratory data for malignant histiocytosis are found. According to literary data, in 27% of patients suffering from RDD, it transforms into malignant histiocytosis. The presented clinical case is interesting not only because of the registered clinical laboratory data of malignant histiocytosis but for the unclear diagnostic and prognostic importance of this phenomenon, as well.


Background: The c-kit is a growth factor receptor that is expressed in a variety of tumors as GIST, leukemia, renal tumors, etc, including Ewing's sarcoma/PNET, this indicates the possible role of this marker in the progression tumor and possible use in treating these malignancies. Investigations initial of inhibitors tirocinasa in development of tumour cells of Ewing's sarcoma/PNET are promising. Objective: To evaluate and detect CD117 positive cases of Ewing sarcoma which could benefit from treatment with tyrosine kinase inhibitors. Material and methods: It is a retrospective study of patients diagnosed with Ewing's sarcoma at the Hospital Solon Espinosa Ayala, SOLCA of Quito, Ecuador, in the period 2003-2007. We reviewed blocks of tissue in paraffin embedded and were processed with the usual technique of antibodies immunoperoxidase CD99 and CD117. The stain was classified low (+) to intense (+++). Results: Of the 16 patients studied, all were positive for CD99, which confirmed the diagnosis of Ewing's sarcoma/PNET; 11 were positive for CD117 (68.75%) and 5 were negative (31.25%). The staining ranged from low (+) to intense (+++), and in all cases were found in the cytoplasm or in the membrane. Conclusions: We findings compared with those described in world literature are similar, with a margin of 0.8%, so we think that a high percentage of these tumors might benefit from therapeutic strategies with the tyrosine kinasa inhibitors (sunitinib / imatinib).

The article deals with the state of cognitive functions (memory, attention and thought process) and asthenic disorders in stroke patients in the process of physical rehabilitation and pharmacotherapy. The study used conventional methods for determining the state of cognitive functions. To improve cognitive abilities in the process of physical rehabilitation in the experimental group of patients, traditional methods and special physical exercises in the form of training tasks for memory, attention and thought processes were used. In the control group of patients only traditional methods of restoration of cognitive functions were used. Both groups of patients took the same drugs to improve cognitive function and relieve symptoms of cerebrogenic asthenia, using classic nootropic drugs (Pyracetam, Phenotropil, Vinpotropil), peptide drugs (Cortexin, Cerebrolysin, Noopept, Semax), antidepressants and tranquilizers (benzodiazepines and non-benzodiazepine). It is determined that the most important indicator of memory quality is short-term memory. In the experimental group in the process of physical rehabilitation revealed an improvement in this memory in 50% of patients, the deterioration of this indicator in 34% of persons, and 16% memory remained at the same level. Short-term memory indices in post-stroke patients of the control group are lower and correspond to: improvement – in 35%, deterioration – in 40%, remained at the same level in 25% of patients. Since the rate of short-term memory is 7 ± 2 units of information, the study showed that in all patients after a stroke, the indicators of storing information in short-term memory have become normal. The study of attention stability revealed that in the control group of patients it is worse than in the experimental group, and that the stability of attention does not depend on the experience of the post-stroke state. Patients with 3 years of post-stroke experience show the same results as patients with 6-month stroke. The study of inductive thinking showed that in both groups of patients it is in good condition. As for the indicators of practical mathematical thinking, 83% of the participants coped with the task in the experimental group, and 17% failed. In the control group, 57% of patients coped with this task, and 43% failed. Only 50% of the patients in the experimental group and 42% of the control group coped with a more difficult task in this type of thinking. The same results were obtained in persons without stroke. This shows that the more difficult tasks of identifying this type of thinking are difficult for people after a stroke. It can be concluded that the mental processes of a person after a stroke are in optimal condition.


Overall mortality and morbidity in infants and neonates undergoing a surgical procedure and general anesthesia in the USA is much higher than in older children [1]. The reasons for this finding may be different neonatal/infant physiology, higher degree of illness, more complex surgical procedures and the effects of anesthesia and analgesia on developing brain. Importantly, the possible effects of blood pressure and cerebral perfusion changes during and after the surgery have to be elucidated in the future [2]. A relatively large volume of animal data evaluating toxicity of anesthetic and analgesic agents on developing brain exists. Data from rodents and newborn monkeys have linked different agents to adverse neurodevelopmental outcomes, such as memory loss [3] and learning difficulties [4]. The most commonly cited mechanisms of injury are increased apoptosis, impaired dendritic arborization and spine formation, changes in neurogenesis and neuronal cytoskeleton as well as altered mitochondrial function [5].


Iridates have recently attracted growing interest because of their potential for realizing various interesting phases like interaction driven Mott-type insulator and magnetically driven Slater-type. In this paper, we present the magnetic and electrical transport properties of polycrystalline Sr2IrO4 synthesized by solid state reaction route. We find a ferromagnetic transition at 240 K. The Curie-Weiss law behavior hold good above the magnetic transition temperature TMag = 240 K with a small effective paramagnetic magnetic moment μeff = 0.25 µB/f.u. and a Curie-Weiss temperature, θCW = +100 K. Zero field cooled (ZFC) magnetization shows a gradual dcrease below 150 K, while same for field cooled (FC) below 50 K. Interestingly, below temperatures, ⁓ 10 K, a sharp increase in ZFC and FC magnetization can be seen. A temperature dependent resistivity reveals insulating behavior followed by power law mechanism. The sintering of sample in air leads to the very low value of resistivity is likely related to Sr or oxygen vacancies.Iridates have recently attracted growing interest because of their potential for realizing various interesting phases like interaction driven Mott-type insulator and magnetically driven Slater-type.

Thermal-simulation test,carbon extraction replica,measurement of hardness and TEM observation technique were used to study the variation of hardness and precipitation behavior during aging at 525℃ for the Nb-containging microalloyed steel deformed at 850℃ and relaxed for different time and then water quenched.The experiment results indicate that two hardness peaks are observed for the steel in the process of aging treatment.The first hardness peaks disappears if the samples experienced no relaxation or relaxed for longer time(relaxed for 1000s) after deformation.The small addition of Nb is the key factor for the occuring of the hardness peaks compared with the experimental results of C-Mn steel.The observation of TEM shows that the very fine precipitates formed in austenite before phase transformation grow gradually and the size of the coarsened particles keeps unchange in the aging process.The second hardness peak result from the further precipitates that nucleate in α phase.


A simplified method was developed for determining the residue of beta-cypermethrin pesticide in Cornus officinalis using HPLC for analysis.The QuEChERS(quick,easy,cheap,effective,rugged and safe)sample preparation method was modified to produce good analytical results for pesticide beta-cypermethrin.The pesticide was extracted from samples with acetonitrile,and purified by matrix solid-phase dispersion using anhydrous MgSO4,PSA and C18.The results showed that good linearity for beta-cypermethrin existed in the range of 0.03-0.12 μg with the correlation coefficient of 0.998 6.The detection limit of the instrument was 1.5×10-11 g.Use of matrix-matched standards provided acceptable results for pesticide beta-cypermethrin with overall average recovery between 80% and 94%.The consistent RSD was 4.5% for pesticide in sarcocarp and 7.5% for pesticide in leaf.


Hubble Space Telescope images of NGC 6543 taken in 1994.7 and 2000.7 reveal a pattern of overall expansion of its core over 6 years. Spatial scale changes of the sharp edges of filamentary structures are consistent with purely radial motions. One prolate ellipsoid, E25, lies along the overall symmetry axis of the core. We find that it expands uniformly with an expansion age of 1300 yr. Around it is an unusual feature that appears like the projection of two bubbles joined at a common waist called E105 along the minor axis of the core. The bubbles, whose outline defines the core of NGC 6543, expands with an expansion age of 1500 yr; however, the growth rate of its waist, E105, is about 70% larger than the bubbles. We show how this can be explained geometrically. Three pairs of sinewy low-ionization features, called caps, ansae, and jets, are seen at or beyond the perimeter of the core. Our studies of these features suggest that their expansion ages are somewhat larger than those of E25 or the bubbles. In addition, we find that the [O III] surface brightness has generally increased by as much as 3% and the [N II] flux has decreased by about 7% or more in 6 yr. Flux changes like these are expected for an expanding nebula whose densities and recombination rates decrease and as dense filaments become more permeable to ionizing radiation. We discuss the potential applicability of the interacting stellar wind (ISW) model to the various components in the core of NGC 6543. ISW is very congruent with the structure and expansion of E25. It may apply also to the E105/bubble complex, although this is far from clear. ISW cannot account for the morphologies or formation of the caps, ansae, and jets.


Introduction: When malignant or precocious stroke-prone spontaneously hypertensive rats (M-SHRSP) were given captopril from tenth or eleventh week of age, they lived longer and their blood pressure stayed at about 250mmHg after administration. In their fundi, typical hypertensive papilledema appeared in the late stage of over forty weeks of age. By the time they showed typical hypertensive papilledema, various vascular changes in the optic nerve may have occurred in the early stage. Using histochemical stain methods of acid muchopolysaccharides, we observed the optic nerve changes of M-SHRSP. Materials and Methods: Ten Wistar Kyoto rats (WKY) were used as controls and M-SHRSP with administration were used in the present study. The bulbus was enucleated and the formol fixed tissues were embedded in paraffin through graded alcohol, sectioned, dewaxed, treated with


We have investigated the effect of interferon‐gamma (IFN‐γ) treatment of neuroblastoma cells on the susceptibility to lysis by lymphokine‐activated killer (LAK) cells and examined the participation of cell‐adhesion molecules on the target cells in LAK cell lysis. Untreated neuroblastoma cells expressed lymphocyte‐function‐associated antigen 3 (LFA‐3) and neural‐cell‐adhesion molecule (NCAM), but did not express MHC‐class‐I, MHC‐class‐II, or intercellular‐adhesion molecule 1 (ICAM‐1). IFN‐γ treatment of neuroblastoma cells induced the expression of MHC‐class‐I and ICAM‐1 antigens, but did not affect the expression of MHC‐class‐II, LFA‐3, and NCAM. This was accompanied by an increased susceptibility to lysis by LAK cells. Anti‐ICAM‐1 antibody inhibited partially the increased sensitivity of IFN‐γ‐treated neuroblastoma cells to LAK cell lysis, and blocked completely the increase in binding of LAK cells observed after IFN‐γ treatment of the target cells. These results suggest that the increased LAK sensitivity of IFN‐γ‐treated neuroblastoma cells is partially attributable to the induction of ICAM‐1 on neuroblastoma cells and indicate that post‐binding events also play a role in the increased sensitivity to LAK cell lysis observed after IFN‐γ treatment.


The aim of this research is to evaluate the feasibility of the fibrous media for removal of total suspended solid and oil grease from palm oil mill effluent (POME). Wet lay-up method was adopted for filter fabrication where empty fruit bunches (EFB) were matted together with chitosan in non-woven manner. Chitosan-filled filter media were tested for their ability to reduce Total Suspended Solids (TSS) and Oil & Grease (O&G) from palm oil mill effluent. Filtration process results indicated that chitosan-filled filter media filtration only removed up to 28.14% of TSS and 29.86% of O&G.


The free metaplectic transformation (FMT) is an
‐dimensional linear canonical transform. This transform is much useful, especially in multidimensional signal processing and applications. In this paper, our aim is to achieve an efficient time‐frequency representation of higher‐dimensional nonstationary signals by introducing the novel free metaplectic wave packet transform (FM‐WPT) in
, based on the elegant convolution structure associated with the free metaplectic transforms. The FM‐WPT preserves the properties of classical wave packet transform (WPT) in
 and has better mathematical properties. Further, the validity of the proposed transform is demonstrated via a lucid example. The preliminary analysis encompasses the derivation of fundamental properties of the novel FM‐WPT, including boundedness, reconstruction formula, Moyal's formula, and the reproducing kernel. To extend the scope of the study, we formulate several uncertainty inequalities, including Lieb's inequality, Pitt's inequality, logarithmic inequality, Heisenberg's uncertainty inequality, and Nazarov's uncertainty inequality for the proposed transform.


A series of bis[[(carbamoyl)oxy]methyl]-substituted pyrrole-fused tricyclic heterocycles were synthesized by using 1,3-dipolar cycloaddition reactions with a trifluoromethanesulfonate salt of an appropriate Resissert compound or with a mesoionic oxazolone intermediate. All of the bis(carbamates) were active in vivo against P388 lymphocytic leukemia with 5,6-dihydro-8-methoxy-1,2- bis(hydroxymethyl)pyrrolo[2,1-a]isoquinoline bis[N-(2-propyl)carbamate] (3c) showing the highest level of activity.


Abstract This study described the functions of you know and I mean in contexts of academic seminar discussions by ELF speakers. The data used in the study consisted of the multicultural discussions in the corpus of English as a lingua franca in academic settings (ELFA). The approach of conversation analysis (CA) was used together with corpus techniques with the aim to provide quantitative support to function categorizations which were drawn from qualitative analysis. Results of the study not only demonstrated the multi-functionality of you know and I mean but also suggested that these two discourse markers played specific functions in academic seminar discussions under ELF contexts. In the context of cross-cultural and academic communication where problematic terms may occur, we found that you know was mainly used to achieve clarity, while I mean was primarily used to correct previous statements and dysfluencies. The findings of this study will help ELF speakers communicate more effectively in academic interactions by recognizing the functions of discourse markers and using them properly.


The important stage in a regional asset management system is an assets inventory in order to facilitate the collection of reliable, accurate and up to date assets data. Information on the existence and potential of these assets will support the development of the asset itself so that the regional assets could be utilized optimally and consistent with the objectives to achieve. The cuurent study was aimed to identify important factors of the fixed asset inventory of Bengkalis Regency Government owned land. The sample was 75 respondents taken by purposive sampling technique. The variables in this research are data collection, codification/labeling, grouping/classification, and recording. All variables are measured using five-point Likert scale and analyzed using Factor Analysis by the method of Confirmatory Factor Analysis. The results demonstrated that the fixed asset inventory of Bengkalis Regency Government owned land had been largely carried out in accordance with established mechanisms. Result of construct validity analysis of Confirmatory Factor Analysis (CFA) showed that the important factors of the fixed asset inventory of Bengkalis Regency Government owned land includes four basic variables, namely: data collection, codification/ labeling, grouping/classification and recording.


n April and May of 1660 Samuel Pepys and his cousin and patron, the newly appointed General of the Fleet Edward Mountagu, lay at anchor off Deal awaiting word to sail over to Scheveling and bring back Charles II as the newly restored king of England. To amuse themselves while waiting on the Naseby-to be renamed the Royal Charles once the king stepped on board-they had with them at least two music books published by John Playford, probably Matthew Locke's Little Consort of Three Parts (1656) and the anthology of works by John Hilton, Charles Colman, and others, SelectAyres and Dialoguesfor One, Two, and Three Voyces (1659). It was evidently from the latter book that they had sung, on 24 April, Thomas Brewer's setting of James Shirley's " Turne Amaryllis with which my Lord [that is, Mountagu] was much pleased."' Neither Pepys nor Mountagu had been an avid Royalist or adherent to the Stuart cause in the 165os (although they both certainly warmed to it in May of 1660). Pepys had as a schoolboy witnessed the execution of Charles I and, being at the time what he himself later called a "great roundhead," rejoiced over that event (Diary, entry for 1 November 166o). Mountagu had served in the Parliamentary forces during the first Civil War of 1642-45 and later in Cromwell's government, urging Cromwell himself to become king. But the connection between the Restoration and a Playford songbook would not have been lost on them, on Playford, or on the composers of the works he published-or on the vast majority of the customers frequenting Playford's shop. John Playford was the foremost publisher of music in his generation, from 1651 to his death in late 1686 or early 1687. But he wasn't always or exclusively a publisher of music. He began his publishing career in 1647, in between the two


This paper deals with translation from the perspective of the relevance theory of cognitive pragmatics. It first introduces some basic concepts such as the inferential nature of communication, context and optimal relevance. Then it discusses the relation between relevance theory and translation and expounds the revelation of translation from three aspects.


What makes thinking good? Although both the general processes and the expertise views point to important dimensions of cognition, neither seems to present a full picture. This special issue explores new conceptions of effective thinking that push beyond both. The authors identify new dimensions of cognition that invite a more complex, expanded conception of good thinking -- one that may include, but is not limited to, general processes and expertise. Discussions feature: * an argument that the cognitive concepts embedded within language provide children with cognitive structures for interpreting utterances and holding beliefs * the key role of epistemic games in good thinking * the importance of "mindfulness" -- an open, probabilistic state of mind that involoves the drawing of novel distinctions and the examination of new perspectives * the significance of abstract conceptual structures in thinking * a synthesis of several new views of thinking, including the ones put forth in this special issue, and an argument for a new, expanded conception of mind. The papers collected in this volume bring genuinely fresh perspectives to bear on the nature of good thinking and what education can do to cultivate it. The contributions rest not so much in supplanting a dominant view, but rather in expanding it by prefiguring new directions in the study and teaching of thinking.


A method of determining whether a Doppler effect exists and a system thereof are disclosed. The method comprises the following steps of acquiring respective inertial sensor data of a first mobile equipment node receiving a first signal and a second mobile equipment node sending the first signal, wherein the first signal possesses a sending frequency; using the respective inertial sensor data to determine whether there is the Doppler effect between the first mobile equipment node and the second mobile equipment node.


The origins of the unification of Germany can be traced back to the Vienna Conference in 1815. Following the defeat of Napoleon the old Holy Roman Empire, which had been abolished in 1806, was replaced by a very loose German Confederation under permanent Habsburg/Austrian presidency. The confederation had a Diet – an assembly where representatives of the member states met together – but individual states retained control over such things as their own nationality, army and economy and could negotiate agreements with foreign powers. However, the Austrian presidency meant that Austria was able to exert considerable influence over the member states. The Austrian politician, Metternich, was vehemently opposed to nationalism of all sorts, but especially to German nationalism. He saw the German Confederation as a chance to keep Prussia in check and to oppose the growth of liberalism throughout the German states. He was to prove a significant barrier to German nationalism until his resignation in 1848.


were felt to be due to both the polypoid lesions along his ileocecal valve causing intussusception, and the adhesions and stricturing from diverticular disease leading to small bowel obstruction. Th ough most cases of lipomatosis are asymptomatic, clinical manifestations that may occur include abdominal pain, nausea, vomiting, diarrhea, constipation, and rarely bleeding due to intermittent intussusception. Surgical resection with ileo-colic anastomosis is the defi nitive treatment for lipomatosis in symptomatic individuals. Th is case reminds us as clinicians to be wary of established diagnoses, especially in those patients failing to respond to conventional therapy.


The energy demand for the current society calls for reliable and sustainable energy resources. Solar energy is one such source with availability in abundance worldwide. Also, the recovery of energy lost in the form of waste heat is a means of securing energy sustainability by minimizing losses. Organic solar cells (OSCs) are relevant in solar energy harvesting while thermoelectric power generators (TEGs) are used in recycling waste heat. These devices require functional materials for effective performance. Graphene, because of its outstanding properties, is suited for applications in OSCs and TEGs. It is suitable as an active and interfacial layer material in polymer solar cells; a counter electrode and photoanode additive material in dye sensitized solar cells; interfacial layer material and active layer additive in perovskite solar cells. In these solar cells, graphene mainly aids charge transport thus, improving the energy conversion efficiency. As a thermoelectric material, graphene is limited by its high thermal conductivity and lack of energy band gap which causes a low Seebeck coefficient. But by graphene doping, nanostructuring and structural defects, the thermal conductivity is reduced and the thermopower is increased to improve the ZT. Also, inclusion of graphene in thermoelectric nanocomposites greatly improves the thermal to electric energy conversion efficiency.


Background: Despite being delicate and helpless, the old could contribute monstrously to the development of the network given that they are appropriately thought about. It's a test for each to instruct them for a sound and dynamic maturing. There are various welfare schemes are services provided to elderly population by each and every Government but this is also true that in past few years' number of old age homes are increasing in numbers. Increased old age homes are occupying high number of elderlies but their quality of life is at great question. Therefore, to sensitizing this matter resent a study projected with an aim to assess the effectiveness of nursing intervention package on physical and emotional well-being of elderly residing at selected old age home of Punjab. Method: This was quasi-experimental research in which total 200 old age people were recruited by using non-probability purposive sampling technique and then randomly allocated to two groups the experimental and control group. Experimental group has received an intervention named as nursing intervention package which consisted educational awareness, group therapy and exercise regimen. The pre-test and post-test data were collected by developed tools which is also checked for their feasibility.


Cyanobacteria represent a small taxonomic group of photosynthetic prokaryotes which some of them are capable of N2 fixation and also possess a tremendous potential for producing a wide range of secondary metabolites. It has been suggested that, some of these microorganisms, especially heterocystous cyanobacteria, assist higher plant growth by supplying growth stimulating substances. During a floristic study of algae in the terrestrial habitats of Iran, cyanobacterial taxa presented in natural habitats of a medicinal plant (Tanacetum parthenium), located in Lorestan province (Iran) is isolated and identified. Among identified taxa, two species, Cylindrospermum voukii, and Wollea saccata are reported as new records from Nostocaceae family in Iran. Beside description of the new taxa, general distribution, as well as camera lucida images are included herewith.


By means of selected examples taken from the zeolite and zeotype academic literature, the influence of binders and matrix components upon the performance of heterogeneous catalysts is illustrated. Such effects can be significant, showing that the binders and matrices are far from inert components in many systems and that, accordingly, their role is worthy of greater consideration than has hitherto been the case.


Biased estimators of β in the linear statistical model Y = Xβ + e have been studied by several authors. Many solutions are of the form * = (C + X′X)+ X′Y for some compatible symmetric matrix C. In this note, conditions on the matrix C are developed which show when, component by component, the mean square error of the biased estimator is less than the corresponding mean square error, or variance, of the estimators using the normal equations. That is if * i is the ith component of *, and i is the ith component of = (X′X)−1 X′Y, C is determined so that for each i var ( i *) + (β i * – β i )2 < var ( i ). The implication for Hoer1 and Kennard's, Marquardt's, and Mayer and Wilke's biased estimators are discussed. Subsequently, the singular valued decomposition of X is used to explore — *.


In this digital era, consumers are influenced by various intelligent computing technologies in the age of the Internet of Things (IoT) to enhance their comfort and quality of life. A Smart TV with broadcasting services is considered as an excellent illustration of the digital technologies. Smart TV applications and software are constantly developed, and it has been certified to satisfy EAL2 security requirements. These technologies understand hand movements and responds appropriately.

Characteristic view is an effective way to represent a 3D object through a set of distinct projections from different view aspects. In this paper, we proposed techniques for automatic characteristic views generations by clustering views of the object from multiple view aspect. By considering the resulting clusters as View Topics that describe a set of portraits of the object, the object can be represented by a set of view topics that can be applied to 3D object retrieval with similarity measures based on the Vector Space Model and the Language Model as well as advanced techniques such as RBF Kernel method. Our experiments have demonstrated that our method is not only invariant with respect to rotation and scaling, but also invariant with respect to the object reflection, and achieve an overall better performance than existing methods.

This paper focuses on objective assessment methods of 3D video and presents a novel 3D objective quality assessment method that integrates perceived quality of image and depth. We chose 3D videos in left plus right format as evaluation object and got an overall 3D perception quality value by using the Radical Basis Function (RBF) neural network. The quality scores of image and depth were respectively calculated by SSIM and correlation coefficient algorithm. Experimental results show that the proposed algorithm correlates well with the subjective scores.


Currently,the migrant population of our country is already more than 100,000,000.The practice indicates the migrant population plays an active role in economy development.But allow of no denial,the emergence of the migrant population also causes a series of social security problems.It can be said that the migrant population crimes already constitute the main threat of the coast cities' economy,particularly to the city flourishing region's social security.As a result,the research on migrant population and the crimes seem to be very necessary and urgent.

Start-up and formation of spherical tokamak (ST) plasmas by electron cyclotron heating (ECH) alone without ohmic heating (OH) have been performed in the LATE (Low Aspect ratio Torus Experiment) device. Injecting a 2 GHz/0.1 s microwave pulse at the power range of 20 - 50 kW and increasing the vertical eld with time, the plasma current increases up to 5 kA. The magnetic measurements show that closed ux surfaces are formed and the outer most one has the aspect ratio A 1.4 and the elongation 1.2. The electron density is higher than the plasma cutoff density, suggesting that ECH by mode converted electron Bernstein waves (EBW) occurs. I. Introduction It is expected that ST has good stability and connement properties in high plasmas and the compact fusion reactors may be realized by ST. Experiments in the middle-size ST's such as NSTX and MAST are being performed eagerly and promising results have been obtained [1, 2]. To produce the ST conguration, a large plasma current comparable to the toroidal eld coil current should be driven, while there is a limited space around the center column for central solenoid coils for OH. Therefore, it is necessary to develop a effective current drive (CD) scenario to initiate, raise and sustain the plasma current by non-inductive methods. One of the candidates is the ECH/ECCD method. Using a microwave in the electron cyclotron range of frequency, plasma production, plasma current start-up and sustainment can be realized simultaneously. When it is shown that the ECH/ECCD method is effective to produce sufciently high plasma current and density, fusion ignition may be obtained by applying neutral beam injection (NBI) to this target plasma and the plasma current may be self-sustained by pressure driven current. Thus, central solenoid coils for OH can be removed and the steady state ST fusion reactor with a simple structure will be realized. It should be emphasized that the ECH/ECCD method needs no structures in close proximity to the plasma, which is quite advantageous for the reactor design. Main objectives of the LATE device are to realize startup and formation of ST plasmas by ECH/ECCD alone without OH power (ECH Spherical Tokamak) and also to demonstrate EBW heating and current drive in over dense plasmas. The scenario of such ECH Spherical Tokamak formation is as follows: First, the breakdown and production of a initial plasma is easily obtained near the EC resonance layer. Next, applying a weak vertical eld superimposed to a toroidal eld, the eld lines connect the top and the bottom of the plasma and the toroidal current o ws to short the charge separation caused by the grad B drifts in the vertical direction. The external eld with a proper mirror ratio improves


This volume contains papers presented at the Fourth International Conference on Comparative Biology of the Monocotyledons (Monocots IV) and the Fifth International Symposium on Grass Systematics and Evolution held in Copenhagen in 2008. The previous conferences on monocots in this series were held in 1993, 1998 and 2003, with the idea that an interval of 5 years would allow for research to make significant steps forward between conferences, and a glance at the index of the proceedings of the first conference in the series (held at Kew) reminds me how far our ideas about monocot systematics have moved in the intervening years.

In 1993, molecular phylogenetics was still in its (relative) infancy and many of the papers in the proceedings (Rudall et al., 1995) reflect the absence of the phylogenetic analyses that we now take for granted. Composition of some of the major orders and families of monocots was still not resolved, and one of the few papers based on molecular data (Chase et al., 1995, based on rbcL sequences alone) provided evidence for many of these not being monophyletic, as circumscribed at that time.

Moving forward to the proceedings of the Third International Conference (Monocots III; Columbus et al., 2006a, b), many of the papers were based on molecular phylogenetic studies, often with data for multiple loci. The trees presented in these studies had greater taxon sampling, and support for the topologies was considerably greater in many cases than those in earlier studies. Monocot studies had moved to a situation in which phylogenetic hypotheses were becoming evermore stable.

Comparing the proceedings of Monocots III and Monocots IV reveals clear differences in terms of the subject areas. In Monocots III there were, for example, four general phylogenetic papers on monocots, 12 on Asparagales, five on Liliales, plus others on other monocot groups. In contrast, there are no phylogenetic papers on the monocots in general or on Asparagales or Liliales in Monocots IV; in fact there is only one phylogenetic study of an order (Dioscoreales) in this volume. This clearly reflects the increased knowledge of relationships among and between the major groups of monocots. The authors of papers in the latest volume were able to ask questions on the basis of more-or-less established phylogenetic trees for the larger groups, and the volume has, as a result, a rather different flavour, with most of the phylogenetic studies focusing on smaller taxonomic groups with much more detailed taxon sampling (e.g. in several clades of Poaceae).

Comprising 32 papers, this volume represents the state of the art of monocot studies in 2008. Subjects covered, in addition to phylogenetics, include mycoheterotrophy, floral anatomy, pollination, epigenetics, drivers of diversification, complete plastid genomes, fossils and dating of phylogenetic trees. As with the earlier volumes, the editors have brought together an important range of papers written by the experts in their fields. It will be an important volume for years to come and should be given a home in all significant botanical libraries.


Underwater depth measurements and point cloud images can be used for robotic navigation and haptic feedback. Structured Light and Time of Flight (ToF) depth camera systems were tested to demonstrate depth measurements and point cloud imaging underwater. A commercial ToF depth camera was modified to include a movable external light source. Images from depth measurements and constructed point cloud images from underwater tests are shown. A comparison of depth images captured while objects were positioned ~0.10-1.80 m from the camera is presented. Calibration of ToF cameras augmented with movable external light sources for underwater use is discussed.

This paper presents a procedure for solving a robust performance problem for SISO systems using a loop-shaping technique. We investigated first the relationship between a mixed-sensitivity H-infinity optimisation problem and classical loop shaping. It is shown how classical loop shaping can be used to minimise the H-infinity cost function. This then provides insight into a further development of loop shaping to minimise the structured singular value for robust performance. The approach is demonstrated by its application to the control of a robot arm whose moment of inertia varies considerably with angle.


Female Instagram influencers presumably manipulate their online presentations to conform to the "superwoman ideal" (i.e., the idea that women have to excel in multiple roles). Knowledge of how they build such presentations is important to understand how young women's perception of the superwoman ideal might be affected by social media. As such, the current content analytical study (N = 1,200 posts, 60 influencers) examined how female health and beauty influencers present themselves in accordance with the superwoman ideal and whether such presentations vary by culture (i.e., the US, Belgium, and China). Inductive framing analysis revealed that they highlight their excellence in six roles, which focus on appearance, relationships, activities, achievements, wisdom, and expertise. Additional multilevel analyses suggested that besides beauty, it is most important to be perceived as an exciting and experienced individual. These roles are generalizable across cultures, implying that the superwoman ideal is presented identically worldwide.


Value-based pricing of new medicines, when defined as pricing or reimbursement based on economic evaluation, requires the use of a threshold incremental cost-effectiveness ratio. Value-based pricing can leave little room for setting a price above zero for manufacturers of new life-extending add-on medicines that are used in combination regimens. This study aimed to present and explore different methodological approaches for pricing life-extending add-on medicines in this value-based pricing framework. The analysis demonstrated that excluding the costs of background therapy will create opportunity costs. A proportional division of the price can avoid opportunity costs. In the absence of information on relative health benefits, a counterfactual scenario of a head-to-head trial has suggested halving the price of background therapy in the relevant patient subgroups. Overall, the most plausible approach appears to be a proportional division of the total price of the combination therapy, in proportion to the health benefits of the add-on medicine and the background therapy.

The Rp- and Sp-diastereomers of the phosphorothioate-containing oligonucleotide d[ApAp(S)ApA] have been synthesized. They and the tetramer d[ApApApA] were tested as substrates for staphylococcal nuclease, DNase II and spleen phosphodiesterase. For digestions with DNase I these oligonucleotides were converted to the 5'-phosphorylated derivates. The reactions with the nucleases were analysed by HPLC. The phosphorothioate groups of both diastereomers were resistant to the action of staphylococcal nuclease, DNase I and DNase II. While the phosphorothioate group of the Rp-diastereomer was resistant to the action of spleen phosphodiesterase, the Sp-diastereomer was hydrolysed at an estimated rate 1/100 the rate of cleavage of the unmodified tetramer. The presence of the phosphorothioate group in the center of the molecule affected the rate of hydrolysis of neighbouring phosphate groups for some enzymes. In particular, very slow release of 3'-dAMP from the Rp-diastereomer occurred on incubation with staphylococcal nuclease but the Sp-diastereomer was completely resistant. DNase II produced 3'-dAMP quite rapidly from both diastereomers of d[ApAp(S)ApA] and DNase I released 5'-dAMP from both diastereomers of d[pApAp(S)ApA] only slowly.


DUPONT NYLON INTERMEDIATES & Specialties—which markets polymer raw materials and specialty chemicals based on the nylon chain—is starting a glutaric acid business. DuPont hopes that putting millions of pounds of a currently scarce product at customers' disposal will open up latent applications. Glutaric acid, a five-carbon dicarboxylic acid, is a by-product of adipic acid production. DuPont says about 2% of the output of an adipic acid plant is glutaric. However, this chemical doesn't usually reach the market because it is converted into dibasic esters, which DuPont and other adipic acid makers such as Solutia sell as environmentally friendly solvents. DuPont wants to extract glutaric acid and sell it directly to customers in niche applications. This spring, the company is making samples of aqueous glutaric acid available to customers, and it hopes to sell commercial quantities by the end of the year. "Today, glutaric is not readily available anywhere," says Keith ...


The rotational barrier in the N,N-dimethylamide group is studied by proton NMR for N,N-dimethylnicotinamide and two quaternary salts in aqueous solution. The carbon-13 NMR spectra of a number of aromatic N,N-dimethylamides are discussed. A roughly linear correlation is found between the ΔG≠ values of the rotation barriers and the chemical shifts of the carbon atom substituted by the amide group.


The effect of Δ9-tetrahydrocannabinol (THC), cannabidiol, and cannabigerol on some metabolic processes in infant and adult rat brain cortex slices was studied in vitro. With L-leucine-U-14C as the tracer substrate, the incorporation of radioactivity into the protein and nucleic acid fractions was significantly inhibited by THC. The oxygen consumption of the slices, the uptake of L-leucine into the slices, and the evolution of 14CO2 were, however, unaffected by THC. Cannabidiol was comparable in activity to THC but cannabigerol was less active. The pattern of inhibition by THC was also observed when the rat brain cortex slices were stimulated by 100 mM K+ or 10 μM protoveratrine. THC also brought about a significant decrease in the incorporation of uridine-2-14C into the nucleic acid fraction of infant and adult rat brain cortex slices. There was a decreased formation of uridine nucleotides in the presence of THC and an increase in uridine and uracil in the low molecular weight fraction. Experiments with T...

The invention relates to a distribution network fault line selection method based on extensional fusion of pattern spectrum analysis and morphological peak and valley detection, and belongs to the technical field of electrical power system relay protection. When a single-phase ground fault happens to a resonant grounded power distribution network, the fault line selection method with the pattern spectrum analysis has the good line selection effect on a fault with a small initial phase angel, and the fault line selection method with peak and valley detection of each feeder zero-sequence current in the feature frequency band has the good line selection effect on a fault with a large initial phase angel. The initial phase angles are calculated, the extension theory is combined, extensional fusion is carried out on the two line selection methods with the fault initial phase angles as weight distribution factors, and symbols relevant to confidence coefficients are used as criterions to achieve fault line selection. Specific examples and a large number of simulation experiments show that the method has applicability and reliability on different fault lines, fault distances, transitional resistances and fault initial phase angles.


The environment is a place where many people interact. The environment is an early part of human life, how a person's language development starts from the environment. Good or bad humans can be judged from their environment. In everyday life situations, a polite attitude will have a positive impact on social relations with the surrounding environment (Gani, 2019).


Optical absorption spectra are presented for Sm 3+ ions in zinc and alkali zinc borosulphate glasses at room temperature. The absorption bands, responsible for various transitions, are assigned and analysed in terms of a parametrized model Hamiltonian (H,,). Energy levels and reduced matrix elements calculations were carded out using the complete 198 SLJ basis set for the 4f 5(Sm"' > configuration. From optical absorption measurements and using the Judd-Ofelt theory, radiative properties for fluorescent levels of Sm 3+ ions have been predicted. Variation of the energy parameters, intensity parameters and radiative properties of Sm'+ doped glasses is examined. 0 1997 Elsevier Science B.V.


ABSTRACT Hagfish skin has been reported as an important site for ammonia excretion and as the major site of systemic oxygen acquisition. However, whether cutaneous O2 uptake is the dominant route of uptake remains under debate; all evidence supporting this hypothesis has been derived using indirect measurements. Here, we used partitioned chambers and direct measurements of oxygen consumption and ammonia excretion to quantify cutaneous and branchial exchanges in Pacific hagfish (Eptatretus stoutii) at rest and following exhaustive exercise. Hagfish primarily relied on the gills for both O2 uptake (81.0%) and ammonia excretion (70.7%). Following exercise, both O2 uptake and ammonia excretion increased, but only across the gill; cutaneous exchange was not increased. When branchial O2 availability was reduced by exposure to anteriorly localized hypoxia (∼4.6 kPa O2), cutaneous O2 consumption was only slightly elevated on an absolute basis. These results refute a major role for cutaneous O2 acquisition in the Pacific hagfish. Summary: Despite being a highly specialized transport epithelium, the skin of Pacific hagfish does not contribute substantially to O2 uptake even when branchial O2 uptake is severely impaired.


The crossed product of C∗ ‐algebras by groups, groupoids and semigroups are well studied. In this paper we introduce and study the crossed product of C∗ ‐algebras by (locally compact) hypergroups. We calculate the crossed products by finite hypergroups of orders 2 and 3.


The electrochemical corrosion behavior of laser welded 2205 duplex stainless-steel in artificial seawater environment (3.5% NaCl solutions) with different acidity and alkalinity conditions (different pH values) was investigated using different techniques. Namely, capacitance measurements (Mott–Schottky approach), electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The formation of pitting corrosion on the exposure surfaces of the tested duplex stainless-steel samples was investigated and confirmed by characterizing the surface morphology using field emission scanning electron microscope (FE-SEM). Based on the obtained results, a proportional relation has been found between pH value of the solution medium and the generated film resistance due to the processes of charge transfer, which directly affecting the pitting formation and its specifications. Since the film layer composition created on the duplex stainless-steel surface is changes depending on the pH value, it was found that different bilayer structure type was generated according to the acidity or alkalinity level. The presented bilayer is almost composed from metal oxides, such as iron oxide and chromium oxide, as confirmed by Raman Spectroscopy technique. As the pits size and its quantity increased with decreasing pH value, it can be concluded that the corrosion resistance property of the laser welded 2205 duplex stainless-steel sample is improved on the alkalinity direction of the solution. Vice versa, higher acidic solution has more ability for corrosion.


A one‐dimensional electrostatic particle simulation model was constructed to investigate an evolution of the parallel electrostatic potential in the presence of a plasma flow along the mirror field. It is shown that a steady‐state, large‐scale dc potential structure is created as a result of a continuous plasma flow injection, and that the resultant potential difference increases in proportion to the ion bulk flow energy. In the magnetospheric environment, the potential difference is found to be able to exceed 2.5 kV.


The potential for intracranial spread of infection from cholesteatomatous ears is well documented but in many parts of the world this potential may be underestimated. Early appropriate surgical intervention and aggressive antibiotic therapy have rendered this complication less common and less lethal. There is, however, no room for complacency and modern-day otolaryngologists must be well versed in its management. The recent experience of the Departments of Otolaryngology and Neurosurgery at Groote Schuur Hospital in patients with otogenic intradural infective complications is presented and emphasis placed on close co-operation between these two specialities.

Utilizing dynamic resource allocation for load balancing is considered as an important optimization process of task scheduling in cloud computing. A poor scheduling policy may overload certain virtual machines while remaining virtual machines are idle. Accordingly, this paper proposes a hybrid load balancing algorithm with combination of Teaching-Learning-Based Optimization (TLBO) and Grey Wolves Optimization algorithms, which can well contribute in maximizing the throughput using well balanced load across virtual machines and overcome the problem of trap into local optimum. The hybrid algorithm is benchmarked on eleven test functions and a comparative study is conducted to verify the results with particle swarm optimization (PSO), Biogeography-based optimization (BBO), and GWO. To evaluate the performance of the proposed algorithm for load balancing, the hybrid algorithm is simulated and the experimental results are presented.


Coastal areas situated at lower elevations are becoming more vulnerable to flooding as a result of the accelerating rise in the global sea level. As the sea level rises, so does the groundwater. Barriers designed to shield against marine flooding do not provide protection against flooding caused by rising groundwater. Despite the increasing threat of groundwater flooding, there is limited knowledge about the relationship between sea level rise and groundwater fluctuations. This hinders the ability to adequately consider sea level rise-induced groundwater flooding in adaptation initiatives. This study aims to investigate how local groundwater in Juelsminde, Denmark, responds to changes in sea level and to evaluate the predictability of these changes using a machine learning model. The influence of the sea on the shallow groundwater level was investigated using six groundwater loggers located between 45 and 210 m from the coast. An initial manual analysis of the data revealed a systematic delay in the rise of water levels from the coast to inland areas, with a delay of approximately 15–17 h per 50 m of distance. Subsequently, a support vector regression model was used to predict the groundwater level 24 h into the future. This study shows how the groundwater level in Juelsminde is affected by sea level fluctuations. The results suggest a need for increased emphasis on this topic.

The aim of this research was isolation of starch from barley cultivar Barun, its modification with mixtures: adipic acid/acetanhydride and azelaic acid/acetanhydride (5%) and characterization of properties of native and modified starches, important for starch application in food industry. Thermophysical and pasting characteristics, swelling power, solubility and resistant starch content of native and modified starches were determined. The results showed that modified starches had lower gelatinization enthalpy, higher peak temperature and lower tendency to retrograde than the native starch. Modified starch pastes had lower gelatinization temperature, higher peak viscosity, higher hot and cold paste viscosities, lower breakdown and higher setback values. Swelling power and solubility of modified starches were higher (except SOL (%) of BSAD and BSAZ at 65°C) than the native starch in temperature range 65-85°C, but lower at 95°C. Modifications decreased resistant starch content of starch.


To determine which amino acid residues are essential for the catalytic activity of soybean P-amylase, deoxyoligonucleotide site-directed mutagenesis was employed against aspartyl, glutamyl, and cysteinyl residues located in highly conserved regions found in P-amylase family to date. Both substitution of aspartic acid at position 101 and that of glutamic acid at position 186 of the enzyme by neutral and acidic amino acids, respectively, led to the complete elimination of activity, but did not induce any significant changes in circular dichroic spectra or the binding affinity for cyclomaltohexaose, a substrate analogue. Taking account of the results obtained here, the above two amino acid residues are involved in the catalytic site of soybean P-amylase. The replacement of glutamic acid at position 345 decreased activity to below 6% of the non-mutant level, implying that this residue may also play a crucial role in /I-amylase activity, although it may not be involved at the catalytic site itself. In contrast, substitution of cysteinyl residue at position 95 by a serinyl residue led to a drastic reducing of the optimal temperature (from 50°C to 30"C), suggesting that this cysteinyl residue is responsible for the thermal stability of the enzyme. 8- Amylase (1 ,4-a-D-glucan maltohydrolase) hydrolyzes a-l,4-glucosidic linkage of starch and glycogen with liberation of P-anomeric maltose from the non-reducing ends. This enzyme is found in many plant and bacteria species. Although the physicochemical properties of the enzymes from sweet potato, barley, and soybean have been well investigated [l], the catalytic mechanism of the enzyme has not yet been elucidated. Comparison of deduced sequences of P-amylases originating from plant and bacteria revealed three highly conserved sequences which very likely are involved in the segment assembly of the catalytic site of /I-amylase [2-41. In the case of a-amylase (1,4-a-~-glucan glucanohydrolase) that catalyzes the hydrolysis of 1,4-a-D-glucans, the aspartyl and glutamyl residues contained in highly conserved regions have been identified as catalytic residues by X-ray crystallography [5 -71 and by site-directed mutagenesis [8, 91. Although the action pattern of P-amylase differs from that of a-amylase and there is no significant similarity between the primary sequences, all of the aspartyl and glutamyl residues located in the conserved regions of P-amylase family can be considered possible catalytic residues. Recently, the results of affinity labeling of soybean P-amylase with 2,3epoxy propyl a-D-glucopyranoside suggested that Glu186 was involved in the catalytic site [lo]. In addition, since the enzyme was inactivated by sulfhydryl reagents such as iodoacetamide, N-ethylmaleimide and mercuribenzoate [l , 111, the cysteinyl residues located in the regions may also participate in the catalytic reaction.


High-field transport in graphene is studied by the Monte Carlo simulation. The results indicate velocity and current saturation in agreement with a recent experiment [I. Meric, M. Y. Han, A. F. Young, B. Oezyilmaz, P. Kim, and K. Shepard, Nat. Nanotechnol. 3, 654 (2008)]. The saturation current scales as the square root of the charge density, or equivalently, the square root of the gate overdrive voltage, which is qualitatively different from silicon field-effect transistors. By analytical fitting to the numerical simulation results, a simple expression of the field-dependent mobility is obtained at different strengths of charged impurity scattering.


A new process of extracting chlorophyll from the microwave radiated silkworm was introduced, The process used a little cell disruptions accessory ingredient as the wetting agent for the silkworm and the carrier to accept the microwave energy. The experimental result indicated: the silkworm after pretreatment by microwave radiated, the quantity of chlorophyll was more percent 25 than that of traditional process; the extraction time decreased percent 80 than that of traditional process, the experimental result was satisfied.


Microfinance is a well known terminology used for microcredit and financial services for financially deprived community. Through informal, semi-formal and formal ways different institutions has been providing these services. Expenditure of the industry is considered to be high because of its inherent structure, dealing with small loans and having high risk of recovery. Therefore, expected inefficiency is greater than its profit. There are several factors and reason. Through this study, we analyzed few factors which have a positive or negative relation with the inefficiency of Microfinance in Pakistan. Stochastic frontier analysis (SFA) is used for weighing up a relationship between inefficiency and its determinants. It is seen that the average efficiency of this sector is low, on average the highest technical efficiency score is 87 only. Age and number of clients have a negative relationship with inefficiency whereas for other variable's relationship is conditional on Microfinance Institutions (MFIs) working status. The number of women borrowers and average loan balance has been incorporated in the study to analyze the focus of MFIs, either on mission drift or achievement. We found that microfinance banks (MFBs) are drifting away, however, Non Government Organizations (NGOs) and Rural Support Programs (RSPs) are fulfilling their social mission efficiently. We did not find a strong evidence of mission drift in the industry because microfinance banks considered their social mission on second priority. Hence, if MFBs are drifting away from their social services, it is not unexpected.


Milk is a functional ingredient and good source of nutritional elements for the growth and maintenance of the human body. Of all the milk proteins, casein contributes to as much as 80% the proteins (Roginsky, 2003). It is thought that beta casein variant A1 plays a crucial role in the development of human diseases like heart disease, type 1 diabetes and sudden infant death syndrome as it yields the bioactive peptide casomorphin 7 (Kostyra et al., 2004). Genotyping results have shown that about 80% of Indian native cattle produces beta casein A2 type which is considered to be healthier than A1 milk.


Biogas technology from cow manure in Indonesia has been developing for a long time, but the application of its use as an alternative energy source is not yet widely developed, due to various unknown operations and processes. This research aimed to analyzed of biogas fermentation time in batch system of cow manure. This research used a Fixed Dome type biodigester that had a total volume of 500 litters with its operating system in batches with 80% of the slurry containing cow manure and the rest for the gas chamber. The biogas fermentation time were 5, 10,15,20 25 and 30 days. The raw material from cow manure had an organic COD content of 10.240 mg / l with a pH of 6.7. The C/N feed ratio was set in the condition of 25: 1 and the ratio of slurry of cow manure with water was 1: 1. From the results of the study in batch process, it was found that the longer the fermentation time the higher the methane gas content but the methane gas content decreases on the 30 th day from 59,12% on the 25 th day to 50,04% on the 30 th day of fermentation.

The experimental results show that the peak current and wire tension has the most significant parameters to influence the material removal rate.


The continued logging for hardwood in subtropical rainforests is causing deforestation and the destruction of diverse environmental ecosystems. Synthetic plastics and particle boards containing synthetic binders such as formaldehydes are alternatives to hardwood, both of which are harmful to the environment and human health. To eliminate wood logging, various biomaterials could be used as promising alternatives to wooden materials. Cotton have been shown to be a viable alternative to various types of wood. Binders are essential in the production of composite wood from cotton. Natural, environmentally friendly binders that can economically and technically replace synthetic formaldehydes in particle boards have been sought after by scientists. Almost all identified natural binders are derived from plants. Comparison of the various alternatives reveals that neither alternative has been able to be a complete substitute for synthetic binders for a variety of reasons, including thermal stability and adhesive strength in some cases. There is also a lack of research into glue as a potential alternative, according to the literature. As a result, the goal of thisstudy is to contribute to analyzing this gap by investigating the technological readiness level for an animal-based natural binder that could be used in the production of wood from cotton stalks. This natural animal binder is fabricated in the lab, and itseconomic feasibility is compared to synthetic binders such as formaldehyde and ecofriendly formaldehyde, as well as natural binders such as lignin and cardanol and tannin. The findings indicate that using animal-based alternative binders as a replacement for synthetic binders has a high potential. To confirm the technical feasibility of the animal-based binder, additional research and tests for the physical characteristics of the resulting wood from the binder, such as bonding force, bending strength, and cohesion, would be required.


In this paper, a genetic algorithm (GA) and particle swarm optimization with constriction factor (CFPSO) are proposed for solving the short term multi chain hydrothermal scheduling problem with non smooth fuel cost objective functions. The performance of the proposed techniques is demonstrated on hydrothermal test system comprising of three thermal units and four hydro power plants. A wide range of thermal and hydraulic constraints such as power balance constraint, minimum and maximum limits of hydro and thermal units, water discharge rate limits, reservoir volume limits, initial and end reservoir storage volume constraint and water dynamic balance constraint are taken into consideration. The simulation results obtained from the constriction factor based particle swarm optimization are compared with the outcomes obtained from the genetic algorithm to reveal the validity and verify the feasibility of the proposed methods. The test results show that the particle swarm optimization technique is better solution than genetic algorithm in terms of solution quality and computational time.


In this paper, we propose two beamforming designs for a multiple-input single-output non-orthogonal multiple access system considering the energy efficiency (EE) fairness between users. In particular, two quantitative fairness-based designs are developed to maintain fairness between the users in terms of achieved EE: max-min energy efficiency (MMEE) and proportional fairness (PF) designs. While the MMEE-based design aims to maximize the minimum EE of the users in the system, the PF-based design aims to seek a good balance between the global energy efficiency of the system and the EE fairness between the users. Detailed simulation results indicate that our proposed designs offer many-fold EE improvements over the existing energy-efficient beamforming designs.


In this paper, emulsion explosives were investigated. Rules for the change of output energy of emulsion explosives with different oxygen balance, aluminum powder content, charge condition, decoupling media etc. were studied by means of an explosion water pool. The p–t curves and peak pressure values were obtained. The effects of these factors on shock wave energy, bubble energy and total energy were given. The results show that output energy of emulsion explosives without aluminum powder is lower than that of standard TNT explosives. The total energy of emulsion explosives with zero oxygen balance is only 86 % of that of TNT. In the experiment, output energy of the explosives tends to increase with the increase of aluminum powder content. With aluminum contents from 10 % to 15 %, the total energy is 1.05 and 1.14 time of that of TNT respectively. Energy efficiency is affected with change of decoupling coefficient and media.


Measuring cerebral oxygenation using near‐infrared spectroscopy (NIRS) has taken on an increasingly important role in the field of neonatology. Several companies have already developed commercial devices, and more publications are reporting absolute boundary values or percentiles for neonates. We compared four commercially used devices to discover whether they provided consistent results in the same patients.


In this study,an intelligent electromyography prosthetic hand with adjustable grip speed was developed.In this system,the surface electromyography signals(sEMG) acquierd by surface electrodes was preliminarily amplified about 150 times and processed using frequency domain analysis method.Through threshold and the equivalent calculation,the control signal was input into the driving circuit of DC micro motor for the prosthetic hand.10 volunteers attended the gripping experiments and each experiment was repeated five times.Under the condition that the amplitudes of sEMG were 500,1 000 and 1 500 mV,the mean and standard deviation of the signals,including output voltage,output current and grip strength,were recorded.The relations among output voltage,output current,grip strength and sEMG ampltude were obtained by fitting analysis.The results indicated that the prosthetic hand speed positively corelated with the output voltage.with load but not overload,grip strength increased with the increasing output current.The results proved the stability of the developed system.And the grasping speed of the system can be adjusted as well.The system with adjustable grip speed improves the flexibility of the prosthet hand.

Abstract Objectives: To examine the differences between medical and non-medical practitioners with regard to the selection of potency. Design: Postal survey to medical homoeopaths belonging to the Faculty of Homoeopathy, and to non-medical homoeopaths, members of the Society of Homoeopaths. Participants: One hundred medical homoeopaths and 100 non-medical homoeopaths. Results: Homeopaths from both groups agreed on certain fundamental concepts. Medical and non-medical homoeopaths differ in the prescription of potency most significantly on greater use of LM potencies and greater consideration of pathology by non-medical homeopaths and greater use of a lower potency in the case of an aggravation in medical homeopaths. Conclusions: Despite the differences in education of medical and non-medical homeopaths, there appears to be general agreement on the philosophical aspects of potency prescription.

In this paper we test a new multicategory SVM method, called augmented binary (AB), on microarray gene expression data. The AB SVM is one of the methods generating a multicategory classifier in one step, without dividing the multiclass problem into binary subproblems. This approach can be useful when the number of samples is very low, like in this kind of application. Furthermore, the use of a single SVM, instead of several binary ones, simplifies the search for optimal hyperparameters and allows a consistent output for all the classes.


We present a new distributed computing algorithm, Parallel Pattern Discovery (PPD), for constrained Non-negative Matrix Factorization (NMF). Our implementation offers the ability to constrain a specific pattern for optimization of the data while minimizing reconstruction error. Parallel Pattern Discovery operates within a distributed environment using a message passing interface. Distribution of the PPD algorithm provides better scalability and allows operation in single- or multiple-system environments. The algorithm was tested on a set of time-series, dose-dependent mRNA gene expression data. Parallel Pattern Discovery was found to accurately identify patterns within the data and reconstruct the original matrices. Our NMF algorithm found a smaller reconstruction error when compared against standard NMF algorithms. Development focused on running PPD as part of a system which identifies significantly contributing genes. Parallel Pattern Discovery is first run to find patterns from biological data. It is followed by Gene Set Enrichment (GSE) which takes the pattern data and relates it back to genetic pathways.


Will the current wave of regional integration arrangements lead to the world being divided into competing inward-looking trading blocs? Or will it lead to a more open multilateral trading system? Using a multi-country political economy model, and after having shown that global free trade is optimal, the author investigates the possibility of achieving it through regionalism. An outsider country considering entering a trading bloc must weight the tradeoff between the costs of opening its own market to more foreign competition and the gains from getting better access to the bloc's preferential market. The gain of access is always larger, so an outsider would always want to apply for membership in the existing bloc. If the bloc policy is open membership, its expansion would result in global free trade. But if member countries can accept or reject new members, expansion of the bloc is unlikely to yield global free trade. When deciding whether to accept or reject new member, an insider compares the gains from getting preferential access to the new member's market with the losses from having to share its original preferential market with the new member. When the bloc is small, the gains are large enough to offset the losses, so insiders are willing to accept new members. As the bloc expands, the insiders'incentive for expanding decreases, eventually to zero. If only one regional integration arrangement were allowed to form, insiders would stop accepting new members when half the world belonged to the bloc. The remaining outsiders would probably form a bloc of their own, which would lead members of the original bloc to increase its size in anticipation of the creation of the second bloc. The threat of regionalism by outsiders would foster larger regional integration arrangements. In this model, the typical sub-game perfect equilibrium would be two blocs, one of them containing roughly two-thirds of the world, the other containing roughly one-third. Even if blocs form and merge simultaneously, yielding progressively larger symmetrical blocs, they would fail to converge in a single bloc unless the external tariff were low enough. In other words, global free trade could be achieved through bloc expansion if trading blocs lowered their external tariffs when abolishing their internal tariffs.


A girl of more than five years was discovered incarcerated in an upstairs room. She had apparently been there since babyhood and was physically malnourished and apathetic as well as mentally blank. Taken first to county home, then to a foster-home, and finally to a school for detective children, she improved very slowly. She is still a virtually unsocialized creature, manifesting many parallels with other cases of isolated children and bearing out the Cooley-Mead-Dewey-Faris theory of socialization.


Abstract. Let ℳ α $\mathcal {M}_{\alpha }$ be the class of moduli of continuity defined by Leindler in [Studia Sci. Math. Hungar. 14 (1979), 431–439], and H ω α (Ω ¯)$H^{\omega _{\alpha }}(\overline{\Omega }) $ be the generalized Hölder class of functions on the closure of the regular hexagon Ω, where 0<α≤1$0<\alpha \le 1$ and ω α ∈ℳ α $\omega _{\alpha }\in \mathcal {M}_{\alpha }$ . The difference f-𝒱 n λ (f)$f-\mathcal {V}_n^{\lambda }(f) $ is estimated in the uniform norm ∥·∥ C(Ω ¯) $\Vert \cdot \Vert _{C(\overline{\Omega })}$ and in the generalized Hölder norm ∥·∥ ω β $\Vert \cdot \Vert _{\omega _\beta }$ , where 𝒱 n λ (f)$\mathcal {V}_n^{\lambda }(f) $ is the nth generalized de la Vallée-Poussin mean of hexagonal Fourier series of f∈H ω α (Ω ¯)$f\in H^{\omega _{\alpha }}(\overline{\Omega }) $ and 0≤β<α≤1$0\le \beta <\alpha \le 1$ .

The Francis Report1 was unequivocal in its findings. The Mid Staffordshire Trust had allowed the following to happen: ' Patients were left in excrement in soiled bed clothes for lengthy periods ' and ' Water was left out of reach'.

Robert Francis observed that: ' Staff treated patients and those close to them with what appeared to be callous indifference. '

And, in conclusion, he wrote that: ' Patients must be the first priority in all of what the NHS does … (and) receive effective care from caring, compassionate and committed staff, working within a common culture. ' 1

What went on in the Mid Staffs Trust is a chilling indictment of what happens when we lose sight of the importance of kindness when caring for our patients.

This lecture is about the importance of kindness in the consultation and in our relationships with others. It is based on a lecture given to RCGP Wales and is a brief synopsis of its content. Unfortunately, space does not permit a detailed examination of the key themes of the lecture. Interested readers are, therefore, invited to read the full text through the link at the end of this paper. In summary, my main contentions are that it is kindness which makes us human , builds resilience, and makes us better doctors and better people.

Although we may not be sure exactly what kindness is, we can all recognise it when we see it! Indeed, it is often the case than nothing upsets us more than when someone is being deliberately unkind to us or others. How to define kindness?

Cole-King and Gilbert have defined compassion (or kindness) as being ' sensitivity to the distress of … others with a commitment to try and do something about it'. 2 The key point …


A rapid and facile route for the synthesis of reduced graphene oxide sheets (rGOs) at room temperature by the chemical reduction of graphene oxide using Zn/acid in aqueous solution is demonstrated.


The French Megajoule Project requires polarizers with high laser-induced damage thresholds. Such polarizers must be deposited on silica substrates, which are commonly prone to stress leading to early failure. Better stress control in the films require an optimization of the stack design as well as the deposition parameters. The thermal e-beam technique is used. We present the spectral behavior of such 1.03 micrometers polarizers in air and under vacuum at the Brewster incidence angle of 55 degrees 4 along with the damage test results.


Background: The extracellular Vibrio cholerae protease, VesB, is expressed in vitro and in stools of cholera patients. Results: VesB is homologous to trypsin and thrombin and the C-terminal domain has an immunoglobulin-fold. Conclusion: In contrast to thrombin, but similar to trypsin, VesB is not activated by sodium. Significance: This is the first structure of a bacterial modular trypsin-like protease. The chymotrypsin subfamily A of serine proteases consists primarily of eukaryotic proteases, including only a few proteases of bacterial origin. VesB, a newly identified serine protease that is secreted by the type II secretion system in Vibrio cholerae, belongs to this subfamily. VesB is likely produced as a zymogen because sequence alignment with trypsinogen identified a putative cleavage site for activation and a catalytic triad, His-Asp-Ser. Using synthetic peptides, VesB efficiently cleaved a trypsin substrate, but not chymotrypsin and elastase substrates. The reversible serine protease inhibitor, benzamidine, inhibited VesB and served as an immobilized ligand for VesB affinity purification, further indicating its relationship with trypsin-like enzymes. Consistent with this family of serine proteases, N-terminal sequencing implied that the propeptide is removed in the secreted form of VesB. Separate mutagenesis of the activation site and catalytic serine rendered VesB inactive, confirming the importance of these features for activity, but not for secretion. Similar to trypsin but, in contrast to thrombin and other coagulation factors, Na+ did not stimulate the activity of VesB, despite containing the Tyr250 signature. The crystal structure of catalytically inactive pro-VesB revealed that the protease domain is structurally similar to trypsinogen. The C-terminal domain of VesB was found to adopt an immunoglobulin (Ig)-fold that is structurally homologous to Ig-folds of other extracellular Vibrio proteins. Possible roles of the Ig-fold domain in stability, substrate specificity, cell surface association, and type II secretion of VesB, the first bacterial multidomain trypsin-like protease with known structure, are discussed.


Trials referring applicability of the final product, such as durability tests to fungi and termites are crucial in developing panels. Therefore, panels made with different percentages of sugarcane bagasse particles (Saccharum sp.) and  eucalyptus fiber (Eucalyptus grandis), bounded with two dosages of urea formaldehyde resin (13% and 16%), were evaluated for biological resistance (bioassays) to termites and fungi, which is fundamental in defining use and application of the final product. We used the termite species Reticulitermes santonensis, rhinotermitidade, and the fungy Pleurotus ostreatus, a white rot basidiomycete, according to AFNOR standardization procedures. In general, the new panels were not resistant to bioassays and there was a similarity in the dynamics of attack and mass loss among the different doses of resin applied, thus evidencing the need of applying protective coating on the panels surface or adding termiticide and fungicide products.


Purpose – The purpose of this paper is to test whether work engagement can be predicted by two core dimensions, energy and involvement, both at the individual and team levels. Design/methodology/approach – Based on the circumplex model of affective well-being (Russell, 1980), the authors propose the work engagement grid and collect data on individual and team work engagement (TWE) from two different samples (n=1,192 individuals). Findings – Results show a significant positive relationship between the individual engagement grid and individual work engagement. However, only the energy dimension significantly predicted TWE. The authors also provide evidences for the relationship between the engagement grid and related variables (e.g. adaptive performance, team cohesion, satisfaction), and show that the combination of energy and involvement present smaller correlations with those variables than the complete engagement scales. Research limitations/implications – Data were collected from simulation samples, the...


Objective
To investigate the clinical effects of evidence-based nursing on reducing the complications after total hysterectomy.

Methods
A total of 200 cases patients undergoing total hysterectomy were divided into two groups, 100 patients before the application of evidence-based nursing as control group and 100 patients after the application of evidence-based nursing as observation group. The incidence of complications, in-hospital time and nursing satisfaction were compared between two groups.

Results
The incidence of postoperative pyrexia, residual uterine bleeding, bladder dysfunction in observation group were significantly less than those in control group(P< 0.05). The in-hospital time in observation group was significantly less than that in control group(P< 0.05). The nursing satisfaction in observation group was significantly higher than that in control group (P<0.05).

Conclusions
The evidence-based nursing has a great clinical effects on reducing the complications after total hysterectomy, which lead to a less in-hospital time and higher nursing satisfaction and makes it worth for clinical application.

Key words:
Total hysterectomy; Complications; Evidence- based nursing


The European Standards Organisation (CEN) has planned to develop a complete set of harmonized European building standards. The Eurocodes, being the design standards, form part of this total system of European standards, together with standards for fabrication and erection and product standards. After a period of experimental use of the ENV(European Pre Standard)-versions of the Eurocodes, these are now converted into official EN`s (European Standards). Design of composite steel and concrete buildings and bridges is covered by Eurocode 4. An overview will be given of the historic development of Eurocode 4, the structure and contents of the EN version and the present status and planning for completion. The Eurocode treatment of some selected technical items will be presented in more detail.
