Histological examination of H&E stained sections of ovaries collected from cyclic and acyclicbuffaloes (n=6/group) was done in order to evaluate the degree of follicular atresia. The percentages of healthy and atretic follicles were different (P<0.05) between cyclic (53.1% and 46.9%, respectively) and acyclic (10.7% and 89.3%, respectively) buffaloes. Electrophoretic patterns of follicular fl uid proteins, studied by SDS-PAGE of follicular fl uid samples aspirated from small (5.06.9 mm), medium (7.0-9.9 mm) and large (≥ 10 mm) follicles of cyclic and acyclic buffaloes (n= 6/group), did not reveal any apparent differences between the groups. DNA fragmentation patterns evaluated by using DNA isolated from the cell pellets obtained after centrifugation of the follicular fl uid samples from small-, medium- and largesized follicles of cyclic and acyclic buffaloes (n=5/ group) showed a typical apoptotic oligonucleosome ladder pattern in the acyclic group. In conclusion, these results indicate an increased rate of follicular atresia without any qualitative changes in the follicular fl uid proteins during ovarian acyclicity in buffalo.


The utility model discloses a gating system in a die for preparing an air chamber bracket. The gating system comprises a straight gate runner. The bottom of the straight gate runner is communicated with a cross gate runner, the cross gate runner is communicated with an inner gate runner, and the inner gate runner are led to a die cavity corresponding to the bottom of the air chamber bracket. The gating system in the die for preparing the air chamber bracket accelerates the flow rate of molten steel, and temperature difference of a cast is smaller. As the position of the bottom part is close to a gate, the problem of shrinkage cavity is solved, and the qualification rate of the product is improved.


1) This study was conducted to investigate the potential of the neutral extract (NE) prepared by treating P. radiata bark with aqueous NaHCO3 solution as a natural dyestuff. Silk and cotton fabrics were dyed at four different NE concentrations, 0.5%, 1.0%, 1.5%, and 2.0% o.w.b. (on the weight of bath). The fabric to liquid ratio of 1 : 50, dyeing temperature of 90 o C, and dyeing time of 90 min were used as the fixed condition. The appropriate NE dyeing concentration of silk and cotton fabrics was 1.5% o.w.b. Colors of the dyed silk and cotton fabrics were brown and light brown, respectively. From colorfastness assessment, both dyed silk and cotton showed good washing and rubbing fastness, but poor light fastness. NE dyed fabrics exhibited excellent ammonia deodorization property and antibacterial activity against Staphylococcus aureus and Klebsiella pneumoniae. Therefore, NE of P. radiata bark could have the potential for use as a functional brown dyestuff.


Corona virus began to run the world in 2019, and started to enter Indonesia in 2020. The government of Indonesia then implemented an alert status telated to public health, and made effort to increase people's immunity through various ways, where one of which is by vaccination. However, there is a lot of Indonesian refuse to take the vaccine due to their believe, and the massive publication in media that sayas a lot of people die since they had vaccination. Institut Teknologi dan Bisnis Sabda Setia collaborate with Dinas Kesehatan, Pengendalian Penduduk, dan Keluarga Berencana socializing the benefits of vaccination, especially the third vaccination called booster to the community in Bengkayang regency. The socialization attended by 100 people from all over Bengkayang. At the end of the socialization, both parties agreed to sign a declaration of the willingness of all officials to carry out the third vaccine.


Abstract This paper describes the Analytic Hierarchy Process as a tool that can facilitate decisionmaking related to some of the critical aspects in maintenance or after-sales area, permitting the alignment of actions with the business' objectives. Actual situations evidence how adopted decisions can change the boundary conditions of the system where the AHP is being applied. Therefore, this research is intended to provide a dynamic view of the AHP method, considering the alternatives as temporary variables and obtaining finally not only one good choice for a specific moment but a range of decisions which present different trends with the time. With this purpose this paper starts with a short literature review and the general characteristics of the AHP method. Afterwards, the paper presents the problematic that appears frequently in actual situations which justify the development of this research. Once described the uncertainty appeared after the AHP implementation, the proposed methodology called DAHP (Dynamic Analytic Hierarchy Process) is presented. Finally, this paper concludes with the main points of the research suggesting applications and further extensions.

Afterwards, an improved version of water-filling algorithm is proposed for distributed multi input multi output systems in underground tunnels. The proposed algorithm is based on the conventional water-filling and Nash equilibrium approaches. It is believed that the designed scheme can enhance both the channel capacity and system performance for distributed multi input multi output in underground tunnel systems.


1 The early tombs on Cemetery A have been dated on archaeological grounds to the second half of the 11th century, the late tombs to the turn of the 13th century, cf. W. Godlewski, PAM XV, Reports 2003 (2004), 144-145. 2 Cf. Nd.02.245 and Nd.02.168, in W. Godlewski, "Naqlun. Excavations 2002", PAM XIV, Reports 2002 (2003), 167, Fig. 3. 3 B. Czaja-Szewczak, "Naqlun. Textiles conservation 2001", PAM XIII, Reports 2001 (2002), 182-183, Fig. 3. The main part of the textiles excavated in Naqlun until the end of the campaign of 2003 is to be dated in the 11th and 12th century, based on their designs and Arabic inscriptions.1 Most of them come from the 12th century and consist of linen fabrics, even batistes, decorated with ornamental bands in fine silk and linen tapestries, or with fine silk embroideries. Such textiles are the characteristic products of the official and public textile manufactories (tiraz, pl. turuz) in the Nile Delta and in Cairo. Only two examples of the typical Fayum woolen fabrics with special "Coptic" design and inscription were found (Nd.02.210 from T. 298; Nd.02.174 from T. 300). And only one shows the very special socalled tree-like kufi-style of the Fayum (Nd.02.210).

* Extracted from the dissertation: "Fatores associados ao abandono do acompanhamento clínico-laboratorial após acidente de trabalho com material biológico", Programa de Pós-Graduação em Enfermagem, Faculdade de Enfermagem, Universidade Federal de Goiás, 2018. 1 Universidade Federal de Goiás, Faculdade de Enfermagem, Programa de Pós-Graduação em Enfermagem, Goiânia, GO, Brazil. 2 Pontifícia Universidade Católica de Goiás, Departamento de Enfermagem, Goiânia, GO, Brazil. ABSTRACT Objective: To analyze the epidemiology of abandoning clinical and laboratory follow-up among health workers who suffered accidents with biological material. Method: Cohort study based on reported work accidents with biological material in Goiânia/Goiás. Data were analyzed in Stata with descriptive and analytical statistics. Results: 2,104 exposures of the 8,596 reported accidents were analyzed, most of them involving females with completed high school education and belonging to the nursing staff. The accidents predominantly occurred by percutaneous injury involving a needle with lumen during medication administration or vascular access. Follow-up abandonment rate was 41.5%. Predictive factors for discontinuing clinical and laboratory follow-up were age, occupation, use of personal protective equipment (gowns), the object involved in the accident, situation in the labor market, circumstance of exposure and recommended prophylactic conduct. Conclusion: Given the high abandonment rate found, it is suggested to implement strategies to ensure follow-up and reduce risks to health workers.


An Italian-Dutch satellite for X-ray astronomy (SAX), which covers energies between 0.1 and 300 keV with unprecedented resolution, was successfully launched from Cape Canaveral at the end of April. The satellite was funded by the Italian Space Agency (ASI) with support from the Netherlands Agency for Aero-space Programmes. The SAX programme manager at ASI, Roberto Ibba, confirmed in early May that the mission was "going extremely well and was already two weeks ahead of schedule in the commissioning phase".


In this paper, presents an efficient education method for training specialized edutainment SW education instructors and drone realistic media creators, not just training to acquire certificates through drone manipulation training. To this end, the NCS-based curriculum was derived. The developed curriculum includes the edutainment drone curriculum and the realistic media creator curriculum. Among them, core responsibilities were defined for the drone control curriculum and core tasks, knowledge, and attitudes were described for each. After that, a detailed curriculum for drone control was derived. In the realistic media creator curriculum, pilot education was conducted to actually produce advertisement videos to foster experts who can work directly in the industrial field. Finally, through holding an online conference in a metaverse environment, a virtual conference was operated to share and discuss media videos produced by trainees. After the end of education, the efficiency of this curriculum was proved through education satisfaction analysis for 46 education graduates. This paper presented a method to achieve internalization of SW education in non-face-to-face online education that our society must solve after post-COVID-19. In addition, an efficient educational method in a realistic media environment was suggested by showing a realistic media creator training curriculum, pilot programs, and metaverse conference management cases.


For study the fluorine and arsenic content and pollution route of the grain in "coal-burning " endemic fluorosis area in Yunnan—Guizhou area and the effect of improved oven for defluorination(OD) in preventing coal-burning chronic fluorosis and the situation of OD use in fluorosis areas in Yunnan—Guizhou Provinces,the living habits,the way of drying and preservation for grain and the children's dental fluorosis rate about 500 families were investigated in the famous serious fluorosis areas——Zhenxiong,Weixin,Daguan,Yiliang County and Zhaoyang of Zhaotong City in Yunnan Province and Weining County and Bijie County in Guizhou Province,and non-fluorosis areas ——Qiaojia,Ludian County of Zhaotong City in Yunnan Province during Apr. 2005 to Dec. 2008. The fluorine content of grain before and after dried in both using and no using OD areas were analyzed.The results show:the fluorine and arsenic content in most fresh grain are lower or a little more over the state standard,the fluorine content in most fresh corn between 1~2μg/g and arsenic content is lower than 0.1μg/g,general in 0.01 to 0.05μg/g,both in the fluorosis area or no infect area. But after about 10 days dried by burning coal quickly,the fluorine and arsenic content in the dried corn have a great deal increase,fluorine pollution level of grain dried by burning coal quickly.In the area of using OD or not,the fluorine pollution level of grain dried by burning coal quickly and dental fluorosis rate of local people are near same,in both areas are very high,and both of fluorine pollution level of grain dried by burning coal are over state standard,and arsenic pollution level increase more than 10 times than the fresh corn; In the using or non-using OD districts,dental fluorosis rate of children,who are mainly feed by dried corn by burning coal quickly,come to 100%,and their fluorosis rate are equivalent. The reason of that OD can't decrease the coal-burning endemic fluorosis rate of southwest China is not the lower using rate or incorrect use of OD. The reason is its lower firepower which can't dry grain quickly in a short time. So,the main route of fluorine and arsenic pollution of grain in "coal-burning" in southwest China endemic fluorosis area is the way of using the open oven burning coal to dry the grain. In the using or non-using OD districts,people still use the open oven to dry the grain; no one uses the OD to dry the grain.So,it is not enough to improve oven only for defluorination in preventing "coal-burning endemic fluorosis" in southwestern China,it can not cut off the source of fluorine when grain dried by burning coal,and need add the other way to together to cut off the source of fluorine.


7A04 aluminum alloy with high strength-to-density ratio has been extensively applied for armour material domain.The projectiles normal impacting 7A04 aluminum alloy plates with 10 mm thickness was conduct by light gas gun,where blunt and ogival steel rod projectiles were involved.The damage modes and penetration characteristics of the 7A04 aluminum alloy targets were obtained.The whole impact process and the residual velocity were obtained by the high-speed camera system.The comparison of the initial velocity versus residual velocity between blunt-projectile penetration events and ogival-projectile penetration events indicated that 7A04 aluminum alloy plates own stronger resistance ability to ogival projectile impact than that of blunt projectile.


The sewage treatment factory has the characteristics of environmentally friendly and energy intensiveness. First, the technological process of the sewage treatment system was analyzed. Then, the main energy-consuming model in each process of sewage treatment was constructed. On this basis, the adjustable potential of each device in the sewage treatment process was calculated. Finally, the strategy of sewage treatment system participating in demand response event was proposed. The adjustable potential of sewage treatment system with A/O process can reach up to 30% in the case study, providing effective load resources for grid regulation. The strategy proposed in this paper for the sewage treatment factory to participate in demand response are effective and practical.

31 Objective: There is need of standardized reference values for cardiac dimensions in 32 prenatal life. The objective of the present study was to construct nomograms for fetal 33 cardiac dimensions using a well-defined echocardiographic methodology in a low-risk 34 population. 35 Methods: A prospective cohort study including 602 low-risk singleton pregnancies 36 undergoing a standardized fetal echocardiography to accurately assess fetal cardiac, 37 ventricular and atrial dimensions. Parametric regressions were tested to model each 38 measurement against gestational age from 18 to 41 weeks of gestation. 39 Results: Nomograms were constructed for fetal cardiac dimensions (transverse and 40 longitudinal diameters and areas) of the whole heart, atria and ventricles as well as 41 myocardial wall thicknesses. All dimensions showed a progressive increase with 42 gestational age. The best model for most parameters was a second-degree linear 43 polynomial. Fetal cardiac, ventricular and atrial diameters and areas were successfully 44 obtained in 98.6% of the fetuses, while myocardial wall thicknesses could be obtained 45 in 96.5% of the population. The results showed excellent interobserver and 46 intraobserver reproducibility (ICC >0.811 and ICC >0.957 respectively) 47 Conclusions: We provide standardized and comprehensively evaluated reference 48 values for fetal cardiac morphometric parameters across gestation in a low-risk 49 population. These nomograms would enable the early identification of different patterns 50 of fetal cardiac remodeling. 51 52 53

This preliminary study presents a sound wave visualization method using mechanoluminescent composite diaphragms made of mechanoluminescence particles (SAO). To visualize the acoustic wave, the concept of Cymatics is used to make the sound waves and vibrations observable (the human sense of vision), as it is the most discriminating human sense. The goal of this study is eventually to extract the frequency information from images captured by compact image sensors without fast Fourier transform (FFT) whereas most previous studies on sound visualization focus on a technique used to enhance the understanding of acoustical behaviors, such as reflection, diffraction, and interference. In this study, highly pressure-sensitive mechanoluminescent diaphragms will be fabricated and used to produce the images in response to audible sound excitation such as speech. This initial study will offer the potential application for new means of speech recognition principle because a systematic visual perception of the isolated speech words can be achieved using the proposed sound visualization method.


66% of transformers operating in PLN P3B JB are using open breather type conservator. This means that the probability of oil oxidation is high and hence is the paper hydrolysis. Therefore, the knowledge of degradation level due to hydrolysis is of our interest. Author tries to find evidence of relationship between oil acidity and insulation paper condition by comparing two test parameters (i.e. acidity/neutral number and furan analysis) among 110 units of sample transformers in PLN P3B JB. Furan analysis was used to detect paper degradation, while acidity test used to detect oil oxidation. By identifying the relation of those two parameters, we can measure the effect of oil oxidation to paper condition.


In the Demand Side Management (DSM) context, residential customers have the potential for reducing costs and relieving the grid with non-thermostatic appliances. These appliances might be optimally scheduled by a central entity, taking into account user preferences. However, the user might not be able to communicate its preferences "a-priori", leaving to the central entity the task of understanding preferences that should be learnt without causing discomfort to the user. With this premise, this study aims at exploring a DSM program that learns the acceptance of realistic simulated users to shift in time of home appliances, such as washing machines and dishwashers, analysing the benefits that arise from their inclusion. To this end, the proposed Acceptance Learning Algorithm 2.0 (ALA 2.0) minimises costs in scenarios with different energy sources and with a certain level of acceptance to shift in time, optimally scheduling the appliances according to the boundaries found by the proposed algorithm. ALA 2.0 is able to understand preferences also when modelling a behaviour of the user which is influenced by external factors not directly observable and when users make very few requests, interacting with the user in a simple way. Experimental results highlight that it is possible to understand the acceptance to the shift in time of the simulated users without any prior knowledge and without causing too much discomfort, achieving a win-win situation. As an example, more than 90% of requests were accepted in December, which is chosen as a representative month.


PRESENTATION This is a case of a 9-year-old female patient who fell from her bike 1 month before presentation. At that time, the patient had a radiograph of the right leg performed, which reportedly demonstrated a bone cyst. One month later, the patient presented with 2 days of fevers to 102-F, as well as persistent severe knee pain and swelling. Medical history was noncontributory. On physical examination, she had localized swelling and tenderness over the anterior lower leg just inferior to the knee. The overlying skin appeared normal, with no focal warmth or erythema.


The size dependence of switching fields of permalloy rings is studied by micromagnetic simulations and by magnetoresistance measurements. Experimentally, the switching fields can be obtained from the discontinuities of the magnetoresistance curve. From the simulated hysteresis loops and the magnetoresistance curves obtained by experiment it is shown that the switching field from the vortex state to the reverse onion state increases considerably as decreasing of the lateral size or as increasing of the thickness. There is, however, no significant correlation between the ring size and the switching field from the onion state to the vortex state.


Three micronutrients viz. iron vitamin A and iodine have well-established roles in public health. Iron is added to wheat flour during milling by statutory requirement in several countries. Iodized salt is promoted in geographical regions which are endemic for goitre and several trials are in progress adding vitamin A to the staple food in countries where vitamin A deficiency is a public health problem. Folic acid is now being considered as the next candidate for food fortification by a number of national authorities. The term folate is used to describe members of a family of compounds in which pteroic acid (2 4 6--substituted pteridine ring bound to para-amino benzoic acid) is bound to one or more molecules of L-glutamate. Folic acid is a pteroyl-monoglutamic acid. It is a synthetic folate which is used as a supplement and for food fortification. (excerpt)


This is an account of aspects of a collaboration between Ronald Breslow (originally Professor of Chemistry at Columbia University, also a member of the Biological Sciences Department, now University Professor at Columbia) and Paul Marks (originally Professor ofHumanGenetics andMedicine, Dean of the Faculty ofMedicine, thenVice President forHealth Sciences and Director of the Comprehensive Cancer Center at Columbia University, then President and Chief Executive Officer at Memorial Sloan Kettering Cancer Center, now President Emeritus and Member of the Sloan Kettering Institute) in the invention and development of suberoylanilide hydroxamic acid (SAHA), an effective anticancer agent that has been in human use for years after approval in theUnited States, Canada andmore recently Japan. The Breslow group designed new potential molecules and carried out their syntheses in the Columbia University chemistry department, and submitted them to Paul Marks and Richard Rifkind at the Columbia Cancer Center, and later at the Sloan Kettering Institute for Cancer Research, for biological evaluation. PaulMarks instituted the collaboration, based on some work by Charlotte Friend of Mount Sinai School of Medicine. This is the way most modern pharmaceuticals are created in pharmaceutical companies or in academic medicinal departments. Biologists may be aware of a promising area for drug development, medicinal chemists then design and create candidate molecules and send them to the biologists, who then evaluate them. With promising results, the chemists continue to create new, perhaps better, candidates while the biologists extend testing to animals and then to humans. Successful medicines are then approved for human use. Normally the chemists are aware of compounds that have some promise, based on binding studies, and they can design around those structures. In the case of SAHA, the initial lead, dimethylsulfoxide (DMSO) 1, was very far from a potential medicine so the design was based on a series of hypotheses. Even so, the eventual structure of SAHA proved to be ideal as a binder to the biological target, although this is not how it was discovered. Thus the editors of this volume have invited


A highly sensitive magnetic particle-based chemiluminescence immunoassay(CLIA) technique for assaying thyroid stimulating hormone(TSH) in serum was described.Fluorescein isothiocyanate(FITC) and N-(aminobutyl)-N-(ethylisoluminol)(ABEI) were used to label two different monoclonal antibodies of anti-TSH.Both of the labeled antibodies combined with TSH to form a sandwiched immunoreaction that was monitored by chemiluminescence(CL) detection.The magnetic particles(MPs) that were coated with anti-FITC antibody served as both the solid phase and the separator.The method showed high sensitivty with a detection limit of 0.01 μIU / mL.The coefficient of variation of intra-assay imprecision and the inter-assay imprecision were less than 10%.The average recoveries were 96% ~ 103%.A correlation analysis against an established automated assay generated a correlation coefficient of 0.993 7.The proposed method demonstrates an acceptable performance for quantifying serum TSH and is suitable for the clinical lab.


One of the aims in the Enlightenment period stage was to improve player's delivery. This practice, regarded as a liberal art, was developed into objective rules that were compiled in several treatises on acting. Many of them, written by actors, reveal their dependence on consolidated knowledges or others mimetic arts, like classical rhetoric or painting. Treatises include how to express the passions properly to suit with the new genre: the "drame burgeois". The means by which players get emotional expression appear in "The Paradox of Acting" among others published or translated books through the 18th century: "Le comedien", by Remond de Saint-Albine; "L'art du theater", by F. Riccoboni; "An Essay on the Art of Acting", by A. Hill; "Desengano de los enganos", by A. Rezano Imperial; or "Ideen zu Einer Mimik", by J. J. Engel. These examples, as we can verify in this paper, confirm the European stage interrelationships and the predominance of the French paradigm.


Purpose: The main purpose of the research conducted was the analysis of kinematic and biomechanical parameters measured during manual wheelchair ramp-climbing with the use of the anti-rollback system and the comparison of the values tested with the manual wheelchair climbing the same ramp but without any modifications. The paper presents a quantitative assessment relating to the qualitative research of the anti-rollback system performed by another research team. Method and materials: The article presents the measurement results of the wheelchair motion kinematics and the activity of four upper limb muscles for eight subjects climbing a 4.58° ramp. Each subject propelled the wheelchair both with and without the anti-rollback system. The kinematic parameters were measured by means of two incremental encoders with the resolution of 500 impulses per single revolution of the measurement wheel. Whereas, the muscle activity was measured by means of surface electromyography with the use of Noraxon Mini DTS apparatus equipped with four measurement channels. Results: The surface electromyography measurement indicated an increase in the muscle activity for all four muscles, during the use of the anti-rollback system. The increase was: 18.56% for deltoid muscle anterior, 12.37% for deltoid muscle posteriori, 13.0% for triceps brachii, and 15.44% for extensor carpi radialis longus. As far as the kinematics analysis is concerned, a decrease in the measured kinematic parameters was observed in most participants. The medium velocity of the propelling cycle decreased by 26%. The ratio of the generated power and the loss power in a single propelling cycle λ had decreased by 18%. The least decrease was recorded for the measurement of mechanical energy E and the propelling cycle duration time. For the total mechanical energy, the decrease level was 3%, and for the propelling cycle duration it was 1%. The research carried out did not demonstrate any impact of the anti-rollback system use on the push phase share in the entire propelling cycle.


Finding mentions of chemical names in texts is of huge interest due to its importance in wide-spread application areas. The inherent complex structures of chemical names and the existence of several representations and nomenclatures (like SMILES, InChI, IUPAC) pose a big challenge to their automatic identification and classification. In this paper we present a supervised machine learning approach based on Conditional Random Fields (CRF) to find mentions of IUPAC and IUPAC-like names in scientific text. We identify and implement a very rich feature set for the task without using any domain specific knowledge and/or resources. Experiments are carried out on the benchmark MEDLINE datasets. Evaluation shows encouraging performance with the overall recall, precision and F-measure values of 90.96%, 91.52% and 91.23%, respectively. We also present the scope of comparison to the existing state-of-the-art system(s).


The growth in student enrollment in the engineering programs, low student motivation and poor passing rates in first years' students in a Computer Science undergraduate program have demanded the incorporation of active learning strategies into the classroom in order to improve problem solving skills. This article describes a proposal and preliminary results of incorporating technologybased teaching strategies. The Analysis-Design-ProgrammingTesting (ADPT) teaching strategy was applied in the classroom, combined with a Flipped Classroom (FC) methodology. Preliminary results show clear benefits related to the availability of support media resources, increased time dedicated to solving problems in the classroom, and the creation of a collaborative and challenging classroom


We introduce a micro-macro parareal algorithm for the time-parallel integration of multiscale-in-time systems. The algorithm first computes a cheap, but inaccurate, solution using a coarse propagator (simulating an approximate slow macroscopic model), which is iteratively corrected using a fine-scale propagator (accurately simulating the full microscopic dynamics). This correction is done in parallel over many subintervals, thereby reducing the wall-clock time needed to obtain the solution, compared to the integration of the full microscopic model over the complete time interval. We provide a numerical analysis of the algorithm for a prototypical example of a micro-macro model, namely, singularly perturbed ordinary differential equations. We show that the computed solution converges to the full microscopic solution (when the parareal iterations proceed) only if special care is taken during the coupling of the microscopic and macroscopic levels of description. The error bound depends on the modeling error ...


The proton N.M.R. spectrum of Me2Cd partially oriented in the nematic phase of EBBA has been recorded and analysed to yield values of D HH, D HH' and D CdH, which suggest that the geometry may differ from that found in the gaseous phase. This appears to be due to a reduction of the length of the carbon-cadmium bonds, although the possibilities of distortion of the methyl groups and/or a departure from linearity of the C-Cd-C skeleton cannot be excluded completely. The cadmium shielding anisotropy σ‖-σ⊥ determined by 1H-{111/113Cd} heteronuclear double resonance is + 3400 p.p.m. (if the molecule is linear), which indicates it may contribute significantly to the relaxation of the cadmium nucleus.


Deals with classification of sarcomas using textural features. The authors assume that sarcomas have a single texture and that the same scale is used for photographing the sarcoma images. 80 sorts of sarcomas are selected under those assumptions. First, the authors make database of templates of sarcomas using textural features. The intensity histogram, Fourier power spectrum, runlength matrix, fractal dimension and co-occurrence matrix are used as textural features. Second, sarcomas are collated by using template matching between unknown samples and the templates in the database. The success rate reached 92%. The result of this experiment shows the adequateness of proposed system.


This paper addresses the birth and evolution of new optics degree programs by using the development of optics undergraduate and M.S. degree programs at Rose-Hulman Institute of Technology (RHIT) as an example. It points out some unique steps that were taken in making this program successful.


As the new drilling technology and technique develop, and the various Shale Shakers come into use, the centrifuge in solids control system makes a higher claim for the operation capability and range; It's difficult to improve the traditional centrifuge because the limitation of technology and structural character itself; the authors of the paper analyze the restrained factor that the processing capacity of the drilling fluid centrifuge can't be raised currently both home and abroad, and presente the operation principle and characteristics of a certern new centrifuge, it is recognized the technical innovation of improving centrifuge processing capacity is scattering feeding, two times acceleration, feeding from the outlet and theframe-shaped crew structure. In the meantime, the authors study the internal fluid field in the centrifuge, give out the mathematics model based on the N-S equation, redefine a boundary condition according to the work characteristics and get the calculating method for processing capacity. It proves the flexibility of the model through the contrasting data between the calculation and the in-situ test.


A plasma filament is generated upstream of the fuel jet through quasi-dc discharge in a scramjet combustor. The effects of the plasma filament on fuel mixing and combustion are numerically investigated based on the dominant thermal blocking mechanism. Results have shown that temperature distribution of the whole flowfield is changed prominently due to heat release from the plasma filament. Since the shock waves induced by the transverse fuel jet are partly weakened and move upstream by the plasma filament, the separation zone upstream of the fuel orifice can be controlled to provide a better combustion environment. Compared with the no-plasma case, more water appears in higher space above the bottom wall while less near the bottom wall of combustor. Although the stagnation pressure loss increases a little owing to the plasma filament, the combustion efficiency rises obviously with only a little external energy addition.


The continuous coupling function in quantum impurity problems is exactly partitioned into a part represented by a finite size Wilson chain and a part represented by a set of additional reservoirs, each coupled to one Wilson chain site. These additional reservoirs represent high-energy modes of the environment neglected by the numerical renormalization group and are required to restore the continuum limit of the original problem. We present a hybrid time-dependent numerical renormalization group approach which combines an accurate numerical renormalization group treatment of the non-equilibrium dynamics on the finite size Wilson chain with a Bloch-Redfield formalism to include the effect of these additional reservoirs. Our approach overcomes the intrinsic shortcoming of the time-dependent numerical renormalization group approach induced by the bath discretization with a Wilson parameter $\Lambda > 1$. We analytically prove that for a system with a single chemical potential, the thermal equilibrium reduced density operator is the steady-state solution of the Bloch-Redfield master equation. For the numerical solution of this master equation a Lanczos method is employed which couples all energy shells of the numerical renormalization group. The presented hybrid approach is applied to the real-time dynamics in correlated fermionic quantum-impurity systems. An analytical solution of the resonant-level model serves as a benchmark for the accuracy of the method which is then applied to non-trivial models, such as the interacting resonant-level model and the single impurity Anderson model.


Graphene-like nanoribbons (GLNRs) were fabricated (length—20 μm; width—2 μm) and subjected to blast-like pulsed pressure >1.5 GPa (pulse speed ≈1 Mach, impulse duration, ≈µs) to examine the amount of absorption. GLNRs prepared by the chemical vapor deposition technique via controlled biomass combustion were subjected to investigate the structure–property characteristics using microspectroscopic techniques. Following this, GLNRs were employed to high strain rate (HSR) studies with the help of the technique known as split Hopkinson pressure bar (SHPB) to evaluate numerous dynamic parameters. The parameters were extracted from variations in the stress and strain rates. Their analysis provided insight into the damping response of blast energy within GLNRs. By and large, the impact generated modified the microstructure, exhibiting modifications in the number of layers, conjugated loops, and dynamic disorder. Signal processing analysis carried out for incident and transmitted impulse pressure revealed an interaction mechanism of shock wave with GLNR. Details are presented.


This study aims to analyze the direct and indirect correlation between environment-based curriculum, teacher pedagogical competence and learning quality through literacy learning. This research used a correlational study with a quantitative approach. Two hundred and eighteen junior high school teachers at adiwiyata schools were involved as population of this study.

The results of the study show that there is a correlation between: (1) environment-based curriculum and learning quality, (2) teacher pedagogic competence and learning quality, (3) literacy learning and learning quality, (4) environment-based curriculum and literacy learning, (5) competency teacher pedagogy with literacy learning, (6) the correlation between environmentbased curriculum and learning quality through literacy learning, (7) the correlation between teacher pedagogic competence and learning quality through literacy learning


Abstract A Monte-Carlo-program has been used to study the channelling process in NbC-single crystals implanted with C-ions at 830°C. The dechannelling yields measured in the ⟨110⟩-direction separately for the Nb- and the C-sublattice are compared to calculated results. In the calculation two defect models (statistically displaced C-atoms and stacking faults) were applied and the characteristic parameters for these models were varied in order to reproduce the behavior of the experimental spectra. The best agreement was obtained by assuming a defect structure consisting of stacking faults with a Burger's vector of a/6 [112] and a stacking fault length of 7 nm. The analyzing ion beam energy was varied in the cal- culation and the expected energy independence of the dechannelling yield for stacking faults was found which lies in reasonable agreement with the experimental values.


The analysis of Bulgarian da-questions shows that not all forms can realize the general factual meaning of the imperfective verbs (IPF). Thus, in both the independent da-questions with a predicate in present tense in Bulgarian and the questions with infinitive in Russian occurs the general factual meaning of IPF denoting a specific single action, thought as a fact. If the question concerns the plan of the past, then the forms of the perfect of IPF verb can express both specific general factual and existential general factual. Only in the latter case, а perfective verb cannot replace the imperfective one.

: Environmental agencies of several countries produced reports that show an increase in greenhouse gas emissions. These documents also indicate that the transport segment has a significant influence on the results, and the heavy-duty vehicles are one of the main contributors. In order to improve the efficiency of this segment, many studies are being developed, such as velocity profile optimization. This strategy aims to determine a velocity profile that minimizes the energy consumption of the vehicle over a determined route by respecting the constraints (time, distance, traffic lights, velocity, and road topography). This can be solved as an optimal control problem which enables a quasi-static and dynamic approach. In this paper, it is proposed to compare the results of a quasi-static and dynamic approach by analyzing the respective velocity profiles and fuel consumption. To analyze these questions, it was adopted from the literature a fictitious road topography and a heavy-duty vehicle fuel consumption model. The results were achieved by numerical simulations in the Matlab program.

The present invention relates to an acrylic fiber for artificial hair, which is formed from an acrylic polymer, wherein the acrylic polymer contains acrylonitrile, vinyl chloride and/or vinylidene chloride, and a sulfonic acid-containing vinyl monomer in amounts of 29.5 to 79.5% by weight, 20 to 70% by weight and 0.5 to 5% by weight, respectively, relative to the whole weight of the acrylic polymer, and the content of an organic solvent capable of dissolving the acrylic polymer therein in the acrylic fiber is 0.1 to 3% by weight. The acrylic fiber for artificial hair can be produced by extruding a spinning raw solution containing an acrylic polymer through a spinning nozzle to form a yarn, drawing the yarn to produce a primary draw yarn, washing the draw yarn with water, and impregnating the primary draw yarn that has been washed with water with an organic solvent capable of dissolving the acrylic polymer therein. Provided are: an acrylic fiber for artificial hair, which has good curl set properties with hot water; a method for producing the acrylic fiber; and a head decoration product comprising the acrylic fiber.


Many surgeons view the central problem in congenital pseudarthrosis of the tibia as one of producing union by means of bone grafting and fixation. However, as is apparent from this symposium, this problem is more encompassing. Whereas conventional techniques, e.g. , microvascular pedicle bone grafts and electrical stimulation, might offer new solutions, when they should be used rather than conventional bone grafting procedures is questionable. It would thus appear that despite the feelings of some a ~ t h o r s , l ~ * ' ~ amputation is another procedure that needs careful consideration in the treatment plan for patients with congenital pseudarthrosis of the tibia. Moreover, patients are seeking amputation as a solution to their problems, I . 12.1 7 despite that union may have been achieved. If it could reasonably be determined early in the course of treatment which limbs would not give better functional results than those with a prosthesis, then several advantages could accrue, e.g., many useless operations could be avoided, and earlier amputation could permit an easier adaptation for both parent and child.

Currently, strokes are the leading cause of adult disability in the United States. Traditional treatment and rehabilitation options such as physical therapy and tissue plasminogen activator are limited in their effectiveness and ability to restore mobility and function to the patient. As a result, there exists an opportunity to greatly improve the treatment for strokes. Machine learning, specifically techniques that utilize Brain-Computer Interfaces (BCIs) to help the patient either restore neurologic pathways or effectively communicate with an electronic prosthetic, show promising results when applied to both stroke diagnosis and rehabilitation. In this review, sources that design and implement BCIs for treatment of stroke patients are evaluated and categorized based on their successful applications for stroke diagnosis or stroke rehabilitation. The various machine learning techniques and algorithms that are addressed and combined with BCI technology show that the use of BCIs for stroke treatment is a promising and rapidly expanding field.

Owing to the lack of standards and certified reference materials for a variety of elemental species in specific matrices the application of species unspecific quantification strategies employing ICP-MS detection has gained more and more importance. The comparison of different calibration strategies by assessing their main sources of uncertainty is a prerequisite for accurate results. A flow injection (FI) model experiment, using a constant spike flow provided by a HPLC pump, and the chromatographic separation of three platinum species were conducted for fundamental evaluation of on-line isotope dilution mass spectrometry (IDMS) used for species unspecific quantification. A cisplatin standard solution was injected into a flow supplied by a HPLC pump for the FI study. This flow was mixed with a constant make-up flow containing an isotopically enriched 196Pt standard. A make-up (fsp) flow of 117 mg min−1 was determined gravimetrically. In comparison, a make-up flow calculation based on reverse ID calibration, i.e., injection of a standard solution of natural isotopic composition, was found to produce significantly biased results. Make-up flow values of 174, 148 and 143 mg min−1 were obtained depending on the peak width of the FI signal (0.7, 1.22, 1.39 min, respectively). A full combined uncertainty calculation, accounting for possible sources of uncertainty in the measurement process, was carried out for both methods and compared with an uncertainty budget which was set up for single point external calibration with internal standardization. On-line IDMS based on gravimetric spike mass flow determination showed a total combined uncertainty of 8%. A comparable uncertainty of 9% was calculated for single point external calibration with internal standardization, since with the investigated FI experiment sources of uncertainty such as gradient elution did not need to be considered. The high total combined uncertainty of 17% of the second investigated on-line IDMS procedure is mainly determined by mass-flow determination. Generally, the final combined uncertainty of on-line IDMS quantification was found to critically depend on the number of measured data points s−1 defining the peak. The species unspecific quantification methods were evaluated for HPLC-ICP-MS analysis of cisplatin and two of its hydrolysis products. On-line IDMS based on gravimetrical mass flow determination was an absolute prerequisite for obtaining accurate results in terms of total platinum concentration.

Image segmentation is widely used in the field of image processing. In this paper a novel method isproposed forperforming image segmentation. To overcome the problem of conventional threshold segmentation method, an adaptive local threshold algorithm is proposed. This method works well with images having non-uniform illumination. The problem of Fuzzy C-Means clustering method can be avoided by using kernel based clustering technique. Kernel Fuzzy C-Means clustering method can be used for images having unequal sized clusters. Experiments on the medical images demonstrate that proposed method has better clustering performance.


We investigate the volcanism of the Ksour Mountains, based on a detailed mapping, in order to reconstitute the Triassic-Liassic volcano-evaporitic sequence. Three volcanic units, of basaltic composition, have been recognized: they are separated by silicico-clastic to evaporitic sedimentary layers and topped with Rhaeto-Hettangian carbonates. This sequence describes the syn-rift volcano-sedimentary filling and the transition from an evaporitic cycle to the first open marine incursions heralding the post-rift installation of the Liassic carbonate platform, in the Ksour basin. In this context, the volcanic units witness the different stages in the structuring of the basin. The basalts are low-Ti continental tholeiites, enriched in incompatible elements and displaying a negative Nb anomaly. These chemical characteristics, along with the stratigraphic position of the lava pile, allow to assign this volcanism to the Central Atlantic Magmatic Province (CAMP). Moreover, the chemical composition of basalts shows an upwards decrease of the TiO2 content and an enrichment in incompatible elements (for example La/Yb). This chemical evolution is the same as that recorded by the volcanic units of the Triassic basins in the High Atlas of Morocco, but on a reduced thickness (15m against 300m). The volcanism of the Ksour Mountains represents one of the easternmost witnesses of CAMP, associated with the central Atlantic rifting, at the TriassicJurassic boundary.

Abstract. The reaction of isoprene (C5H8) with hydroxyl radicals has been studied in the absence of nitrogen oxides (NOx) to determine physical and chemical characteristics of the secondary organic aerosol formed. Experiments were conducted using a smog chamber operated in a steady-state mode permitting measurements of moderately low aerosol levels. GC-MS analysis was conducted to measure methyl butenediols in the gas phase and polyols in the aerosol phase. Analyses were made to obtain several bulk aerosol parameters from the reaction including values for the organic mass to organic carbon ratio, the effective enthalpy of vaporization (ΔHvapeff), organic peroxide fraction, and the aerosol yield. The gas phase analysis showed the presence of methacrolein, methyl vinyl ketone, and four isomers of the methyl butenediols. These gas-phase compounds may serve as precursors for one or more of several compounds detected in the aerosol phase including 2-methylglyceric acid, three 2-methyl alkenetriols, and two 2-methyl tetrols. In contrast to most previous studies, the 2-methyl tetrols (and the 2-methyl alkenetriols) were found to form in the absence of acidic sulfate aerosol. However, reaction conditions did not favor the production of HO2 radicals, thus allowing RO2+RO2 reactions to proceed more readily than if higher HO2 levels had been generated. SOA/SOC (i.e. OM/OC) was found to average 1.9 in the absence of NOx. The effective enthalpy of vaporization was measured as 38.6 kJ mol−1, consistent with values used previously in modeling studies. The yields in this work (using an independent technique than used previously) are lower than those of Kroll et al. (2006) for similar aerosol masses. SOC yields reported in this work range from 0.5–1.4% for carbon masses between 17 and 49 μgC m−3.


LOOKING BEYOND SHORT-TERM solutions to the nation's current energy crunch, lawmakers are pushing for more incentives to spur development oftreakthrough technologies that would move the oil-dependent U.S. toward a hydrogen-based economy. "Suddenly, the whole nation is focused on gas prices and our addiction to oil, and Congress is in a panic trying to figure out how to respond," House Science Committee Chairman Sherwood Boehlert (R-N. Y.) remarked at a committee meeting in late April. "Our options in the immediate future are limited, but our options in the mid- and long-term are not. Unless we exercise those options, we are going to lurch from oil crisis to oil crisis, and each one is going to get worse." One strategy that has gained support on Capitol Hill in recent months is the establishment of a national prize competition to encourage the R&D necessary to overcome the technical barriers that currently stand in the way of hydrogen becoming ...


ABSTRACT This study aims to examine whether the characteristics of the child protection systems can explain the demand for emergency child removals at the community level. The material of the study consists of Finnish municipalities (N = 292) and their child protection indicators. The study was undertaken by using a conditional process analysis software programme and estimating the regression coefficients in the conditional model. It was found that family support services reduced the demand for emergency child removals. On average, family support seems to be an effective intervention, and also in case of increasing child welfare notifications. The present study underlines the significance of a system-level approach to child protection.


According to the Survey of Consumer Finances, the fraction of low-income households (defined here as the bottom 20 percent by income) with positive assets has risen considerably over the past two decades from 78.5 percent in 1989 to 90 percent in 2010. In contrast, there has been almost no change in the share of households with positive assets within the top four income quintiles over the past 20 years—within these quintiles, nearly all households own assets.

In the present computing and fast growing world, information plays a key role in humans day to day life. Information can be stored in databases in an organized manner and SQL allows users to access process and manage data on database. But not all users are accustomed to writing SQL queries. This resulted in need for non-sophisticated users to access the database using natural language. A Natural Language Interface for Database (NLIDB) acts as an intelligent interface for database which allows users to access the database by typing requests in their natural language. The paper is going to discuss about a NLIDB system based on HMM. The system contains two modules: linguistic module and database module. Linguistic module makes uses of various Natural Language Processing (NLP) techniques which are used to identify tokens that correspond to the constraints and predicates required to build possible SELECT, WHERE and FROM clauses. The output of linguistic module is passed to database module. Identified tokens are then mapped to SQL query tokens using a query translation algorithm. A template is being used to generate corresponding SQL query. If the algorithm fails to identify sufficient details, a query prediction module based on HMM identifies the attributes and predicates list. The system used either a template based system that produce nearly 100% correct result to user query or prediction module that generate a highest probable result that matches to the user query. No situation exists in which the system fails to produce a result to the NL query.


In electrokinetic decontamination of soil electrodes are buried into the radioactively contaminated soil contained in a radioactive waste drum, and a dc current is supplied, so that the radioactive nuclide and impurities can be removed by the electroosmosis and the electromigration. The anode specifically includes: (1) at least 3 or more metal tubes made of titanium or zircaloy and having a diameter of 5 cm or less; (2) at least 6 or more metal rods made of stainless steel, titanium, or zircaloy; and (3) stainless steel sieves. The cathode is a tube made of carbon steel, stainless steel, or palladium, and has a diameter of 10 cm or less. At an initial stage of the decontamination a peristaltic pump is used to make the soil filled with water to a saturation level. As illustrated the metal rods are welded to the metal tubes to form a polygonal contour and a stainless steel sieve installed between the rods.

CD47 is a widely expressed cell surface receptor that has originally been identified as an integrin‐associated protein. In immune cells, CD47 has been shown to associate in cis with several integrins of the β1 and β3 subfamilies and the one member of the β2 subfamily, αLβ2. Surprisingly, the association of CD47 with integrin Mac‐1 (αMβ2, CD11b/CD18), the major adhesion receptor on the surface of myeloid cells has not been documented. Furthermore, while previous studies focused on the mechanism by which CD47 on various host cells prevents phagocytosis by macrophages, the question as to how CD47 on macrophages may influence the responses of these cells has not been addressed. Here, we demonstrated that CD47 modulates Mac‐1‐dependent macrophage functions. In particular, adhesion of macrophages isolated from CD47‐/‐ mice to fibrinogen and ICAM‐1, the established physiological ligands of Mac‐1 was significantly decreased compared to wild‐type counterparts. Also, spreading of CD47‐deficient macrophages was decreased by four‐ and two‐fold on fibrinogen and ICAM‐1, respectively. Compared to wild‐type macrophages, migration of CD47‐deficient macrophages to the Mac‐1 ligand, the cathelicidin peptide LL‐37 was significantly reduced. The lack of CD47 on the surface of macrophages impaired their ability to fuse in the presence of IL‐4. Finally, the deficiency of CD47 also reduced phagocytosis of opsonized latex beads, a process fully dependent on Mac‐1. The functional link between CD47 and Mac‐1 was confirmed by their physical association in cis on the surface of macrophages and Mac‐1‐expressing HEK293 cells using co‐immunoprecipitation and the proximity ligation assay. Studies with HEK293 ceIls expressing individual αM or β2 integrin subunits of Mac‐1 showed that both subunits can interact with CD47. The activation of cells with PMA, Mn2+, and mAb MEM48 increased the amount of CD47 recovered in immune complexes with Mac‐1, suggesting that CD47 has increased affinity for integrin in the extended conformation. The binding site in CD47 for Mac‐1 was identified in its constituent IgV domain as recombinant IgV blocked the Mac‐1‐CD47 complex formation and inhibited adhesion and phagocytosis. Collectively, these results indicate that Mac‐1 forms a lateral complex with CD47, which regulates important macrophage functions.

Abstract Dune ecosystems along the Great Lakes shoreline provide essential habitat for specialized plant communities and several state and federal listed rare species. I conducted a vegetation survey in Grand Sable Dunes, Pictured Rocks National Lakeshore, MI, in an effort to investigate the hypothesis that physical dune characteristics influence the distribution of encountered listed species of concern. Three species with concern status were encountered (Cirsium pitcheri, Stellaria longipes, and Tanacetum bipinnatum). Overall plant diversity was negatively correlated with soil pH. Increases in dune aspect and slope resulted in increased abundance of C. pitcheri and S. longipes, while T. bipinnatum decreased in abundance. Increases in species richness and plant density resulted in decreased abundance of C. pitcheri and T. bipinnatum, while S. longipes increased in abundance. These three species rarely co-occurred in quadrats. The gradient of dune stabilization that has naturally occurred within Grand Sable Dunes provides the necessary range of distinct microhabitat necessary for C. pitcheri, S. longipes, and T. bipinnatum to establish and maintain populations. Younger foredunes with less vegetation cover are necessary for C. pitcheri and T. bipinnatum. As dunes stabilize and more species colonize, the microhabitat becomes more suitable for S. longipes. Ensuring a natural range of dune stabilization from active foredunes to stable hind dunes will benefit conservation of endangered, threatened, and species of concern.


ABSTRACT Reverse osmosis is the technology commonly used to produce fresh water from brackish groundwater. Due to the reject brine generated in desalination plants by reverse osmosis, vulnerability assessment to define critical areas to monitor waters from desalination has been an important tool for delineating the monitoring networks required for surveillance of potential salinization sites. The objective of this study was to assess the quality of waters sampled in desalination plants by a quality index, which provides a relative assessment of water vulnerability to potential salinization. The present study proposes an index to assess the quality of waters from desalination plants initially using the chemical parameters electrical conductivity, sodium adsorption ratio, Mg2+/Ca2+ ratio, and the ions sodium, chloride and bicarbonate. The index to assess quality of waters from desalination plants showed good performance and can include additional parameters referring to the soil and crop exploited. High values of the relative index of quality of waters from desalination plants are considered as possible indicators of risk of soil salinization and groundwater contamination. The highest level of land use impact on the quality of waters from desalination plants was found in reject brine samples followed by well water samples.

Polycarpon dunense is diploid (2n=16) and can be distinguished from the related taxa by a combination of characters including a small size and a prostrate habit, a glaucous leaf colour, leaf succulence, ovate leaf shape, narrower leaf size, smaller bract length, obtuse sepal apex, and smooth


This paper presents a new system for detecting the railway tracks and avoidance of collision in the tracks. The proposed Solution is based on IR Rays & Sensors. So for Significant energy has been expended in recent years to develop sensitive and repeatable crack detections. Today one of the major problems that railroads have faced since the earliest days is the prevention of service failures in track. As is the case with all modes of high-speed travel, Rail is manufactured in different weights; there are different rail conditions (wear, corrosion etc.) present; there are a significant number of potential defects possible; and the task has to be performed with some speed to reliably inspect the thousands of miles of track stretching across the land failures of an essential component can have serious consequences. The main problem about a railway analysis is detection of cracks in the structure. If these deficiencies are not controlled at early stages they might cause huge economical problems affecting the rail network .The main aim of the work is used to find the detection of cracks in the railway tracks by an IR sensor .Avoidance of collision by fixing the sensors in the train wheels and transmit the rays in the track. Opposite train also have the same option. If two trains are in the same track means the rays will get collides and get reflected back to the respective engines and the LED or Alarm blinks we can stop the train.


A recent advance in the study of the physiology of the mammalian central nervous system (CNS) has been the ability to lesion specific classes of neurons by the use of selective neurotoxins. The dihydroxylated tryptamines, including 5,6-dihydroxytryptamine (5,6-DHT) and 5,7-dihydroxytryptamine (5,7-DHT), structural analogs of 5-hydroxytryptamine (5-HT, serotonin), are effective in lesioning serotonin neurons.' Lesioning by 5,6-DHT is largely restricted to the spinal cord and lower brain stem, and, due to its toxicity, 5,6-DHT can be administered only in a limited range of doses.*, a In contrast, 5,7-DHT induces more extensive destruction of serotonin-containing neurons in both forebrain and brain stem-spinal cord but is evidently less selective, causing toxic damage to norepinephrine neurons as weL4 Pretreatment with desmethylimipramine (DMI) prior to lesioning with 5,7-DHT protects norepinephrine neurons and allows selective destruction of indoleamine neurons in a more extensive distribution throughout the neuroaxis.fi The systemic administration of the serotonin precursor 5-hydroxytryptophan (5-HTP) in rodents so lesioned with DMI plus 5,7-DHT produces a behavioral syndrome of tremor, jerking movements, and seizures. This response may be assessed by pharmacologic and behavioral techniques and permits an evaluation of the function of presumptive central serotonergic synapses in vivo after selective lesioning with serotonin neurotoxins. This myoclonic syndrome that occurs after administration of a serotonin precursor to rodents lesioned with DHT may reflect the development of supersensitivity related to central serotonergic synapses.G-

Sensitivity study of CO 2 injection in CBM reservoir drainage process using two injection models called Musi and Acre at, with simulation time cases of 30 years. Musi model contains five spot and line drive injection models. Acre injection model is often used based on the drainage area of the field, including 5 spot pattern with 3 drainage area are 90, 160, and 360 acre. The level of success and optimization of gas production rate based on many factors of geology, reservoir characteristics, drilling activities, as well as external factors of CO 2 injection, which is associated with the water production during the dewatering process. CO 2 is greater ability to absorb and to adhere on coal matrix surface than methane, and expected to improve the efficiency of methane gas recovery process, which initially absorbed in coal matrix. The Production Profile resulting from Musi five spot and line drive models for Pro-1 well increase with maximum methane gas rate production from 24.68 to 26.12 Mscfpd and from 32.89 to 668.87 Mscfpd with cumulative gas rate production from 7141.04 to 8310.1 Mscfd (8.8 to 35.9% CO2) and from 229.860 to 5843.020 MMscf (99.57% CO 2 ). For Acre model, the 90 acre model is the best model which has a higher maximum methane gas rate production from 22.5578 MMscfd to 37.367 Mmscfd with cumulative from 75.212 MMscf to 94.740 MMscf. Result from sensitivity studies based on the simulation and modeling of CO 2 injection program, was used to observe the production profile as the references to optimize the gas production rate and consideration to the plan of development (POD) in the CBM field. CO 2 injection into the reservoir will also reduce CO 2 emission in the atmosphere, to support efforts in reducing the global warming.


1.1. Ofcom's approach to issues of market definition and the examination of market power in its First Consultation Document was deficient in numerous respects2. It was Sky's expectation that this was essentially the result of the fact that it was a preliminary analysis, as part of a first consultation aimed at eliciting information and comments from consultees, and that the analysis of these matters in Ofcom's Second Consultation Document would, therefore, be substantially improved. Even though Ofcom did not engage in any further discussion with Sky during the preparation of its Second Consultation Document, the significant period of time that elapsed between the end of the first consultation period and the issuing of the Second Consultation Document gave Sky some confidence that this would be the case.


The regional metamorphism which produces glaucophanites can be regarded as metamorphism under low temperature and high pressure. It has been expressed by many authors including the present writer that the glaucophanites have no special characteristics in the chemical composition. However, it is evident from the statistical study of the available chemical data that the metamorphic rocks, especially the green schists in the glaucophanitic regional metamorphic terrains have generally higher content of Na2O and higher ratio of Fe2O3: FeO than the metamorphic rocks subjected to other types of regional metamorphism. These features are considered to be due to the soda-metasomatism and rather high water vapour pressure prevailing in some glaucophanitic regional metamorphic terrains.


: This paper describes the development of a 2-D finite element model for unsteady free-surface flow generated by rapid gate closure. The performance of the model is assessed by comparing its numerical results with those obtained from experiments conducted in a rectangular open channel. Excellent agreement is observed between the model and the experiment. For comparison, a 1-D model is also tested and the results are found to be poor. The 2-D model gives a more realistic description of the flow than that of 1-D approach and the computation is less complicated than that of 3-D approach. The finite element method is a better alternative than the method of characteristics when the problems are of 2 or 3-D nature.

Additionally, the percent variation in each phenotype attributable to genotype was determined using hierarchical models with a likelihood ratio test.


Summary Two methods for calculating the flow of digesta and its constituents from the concentrations of two markers, 51Cr-labelled chromium EDTA (51Cr-EDTA) and 103Ru-labelled ruthenium phenanthroline (103Ru-P), and digesta composition were compared in fistulated sheep fed once daily and in other fistulated sheep fed continuously. One method uses the marker concentrations to calculate the flow of whole digesta directly (double-marker) whereas the other uses the markers to calculate separately the flow of fluid and non-filtrable particles, the sum of which is digesta flow (two-marker). When feed was given continuously, flow values calculated using the double-marker method and the two-marker method, which requires a correction to be made for nonideal behaviour of 51Cr-EDTA, did not differ. When feed was given once daily, the double-marker method consistently overestimated flow relative to the corrected twomarker method but the differences were extremely small (less than 0-8% for digesta flow and 0-5% for nitrogen flow). 51Cr-EDTA as a single marker slightly overestimated digesta flow (up to 2·3%) but grossly overestimated nitrogen flow (up to 22·5%); 103Ru-P as a single marker grossly underestimated both digesta flow (up to 30·5 %) and nitrogen flow (up to 23·1%). It was concluded that the double-marker method is to be preferred when the diet is given continuously or frequently at fixed intervals. When the diet is given once daily, the two- and double-marker methods can be expected to give similar values. Single markers should not be used for estimating the flow of digesta and its constituents when samples are taken from a simple cannula.


In this paper, we develop an analytic model based on the theory of virtual-source emission-diffusion (VS-ED) to describe ambipolar current conduction in ultrathin black phosphorus (BP) field-effect transistors (FETs). Unlike the VS model which is strictly applicable to quasiballistic devices, the VS-ED model can be applied to long-channel devices with drift-diffusive transport. The model comprehends the in-plane band structure anisotropy in BP, as well as the asymmetry in electron and hole current conduction characteristics. The model also includes the effect of Schottky-type source/drain contact resistances, which are voltage-dependent and can significantly limit current conduction in the on-state in BP FETs. Model parameters are extracted using measured data of back-gated BP transistors with gate lengths of 1000 nm and 300 nm with BP thicknesses of 7.3 nm and 8.1 nm, and for the temperature range 180–298 K. Compared to previous BP models that are validated only for room temperature and near-equilibrium bias conditions (low drain-source voltage), we demonstrate an excellent agreement between the model and data over a broad range of bias and temperature values. The model is also validated against numerical technology computer-aided design data of back- and top-gated BP transistors with a channel length of 300 nm and a thickness of 8.1 nm. The model is implemented in Verilog-A, and the capability of the model to handle both dc and transient circuit simulations is demonstrated using SPECTRE. The model not only provides physical insight into technology-device interaction in BP transistors but can also be used to design and optimize BP-based circuits using a standard hierarchical circuit simulator.


Methods of artificially manipulating the athlete's body into an ideal technique for competition in the discus event in track and field has not been firmly established through research studies. Although McLaughlin (1981), Jarver (1980), Moynihan (1983), Woicik (1982), Gambetta (1981), and Wilt (1976) stated their athletes obtained better throwing patterns by using plyometrics than by using traditional training methods, their training methods have not been tested through critical research. McLaughlin (1981) used a platform four inches to six inches in height at the back of the circle and had his athletes land in an exaggerated bent-leg position prior to the drive off the power leg. Jarver (1980) and Gambetta (1 81) had their athletes land in the center of the circle from a 30 to 40 centimeter elevated position and then perform a normal delivery. Wilt (1976) established 12 to 18 inches as his elevation height for throwers to use with five repetitions of six to eight sets.


The purpose of this article is to analyse one of the leastknown works of the poet — the elegy "Na zgon Poezji". This is the one of the last three Norwid's works, and, moreover, the first which is opening the last period of Promethidion's author writings. Abandoned, condemned to poverty and obscurity poet is experiencing a period of deep collapse, which, however, doesn't permit him to stay silent. By reference to Norwid's works, correspondence and biography the author of this paper will try to reconstruct the least known phase of his life – the residence in the shelter of St. Casimir in Ivry.


Albert Einstein is considered the most famous physicist of the 20th century. His name still unfolds a myth: To what end con the human mind reach out? He claimed physics could answer the metaphysical question: Is the human mind able to achieve a theory of everything (TOE)? If the first principle, called God, is in itself determined. then perhaps we can hope to be some day in possession of this theory. Metaphorically speaking, if God is not able to play dice, this means that its does not exists a free being. The article intends to show that Quantum theory reveals this to be wishful thinking that will not stand on experimental approach. Einstein abhorred indeterminism lo physics, because be wonted to avoid a personal God and man as a being endowed with freedom and responsibility.


Experience from avalanche rescues and rescue drills reveals that often the buried victim is not found on the first or even second pass of an organized probe line. Traditional probe spacing used in North America is based on assumptions and practice done nearly 40 years ago (Schild, 1963 and 1973). More recent work by Jamieson and Auger (1997) challenged those assumptions and presented evidence that the original probabilities of detection (POD) were high, but still their probe targets were not human shaped, and thus did not offer a realistic search target. We developed a computer program PROBE that simulates a fully articulated human body, "buries" the body, and then implements the probing technique specified by various command line options. The derived "bodies" offer realistic targets, and the program can compare the PODs for different probe-pole grid patterns. 10,000 trials were run for a variety of probegrid spacings, including the standard coarse probe, Canadian 3-holes-per-step, and European methods. Results suggest significantly lower PODs for the commonly used probe-grid patterns. Search and rescue leaders should reconsider their use of the traditional techniques. Some options are offered that may make searching more efficient, for the sake of the searchers and of the buried victim.

Abstract The aims of the current study were to evaluate the psychometric properties of a short version of the Five Facet Mindfulness Questionnaire (FFMQ-SF-BR) and verify if the addition of wording mechanisms (positive or negative) contributes to the fit of the shortened Brazilian Portuguese version of the FFMQ. Four hundred eight participants answered self-report measurements. Structural equation modelling was employed for both objectives. Adequate model fit was found for the 5-factor FFMQ-SF-BR model, with significant improvements arising from the addition of wording mechanism effects. No evidences of differential item functioning and population heterogeneity were found. Bifactor analysis showed that latent traces are preferred overusing raw sum scores. The FFMQ-SF-BR is suitable to measure mindfulness in the Brazilian population and has the benefits of decreasing data collection length without losing content coverage.


Enzyme linked immunosorbent assay (elisa) was employed to determine the rate of digestion of blood proteins ingested by teneral and non-teneral laboratory reared Glossina morsitans morsitans at different time intervals after feeding. This test showed that non-teneral flies digested the species distinguishing bloodmeal components faster than tenerals. At 48 hr post-feeding, the bloodmeal donor was identifiable in 87.5% of the teneral tsetse and 55.5% of non-teneral tsetse flies. Among 160 bloodmeals of G. m. submorsitans collected from the upper Didessa river valley 54.4% (87/160) were with identifiable hosts, of which warthog accounted for about 52.9 (46/87) of meals, whereas human and buffalo blood accounted for about 21.8% (19/87) and 12.6% (11/87) of the meals, respectively. Others like giraffe, goat, cattle and elephant accounted for few bloodmeals. Thus warthog appeared to be the major host for G. m. submorsitans in the study area.

I argue that we are seeing an increase in theoretical and empirical work that bridges clinical and social psychology. Several factors that have led to this rebirth of interest in integrative social—clinical work are considered. In addition, I outline the type of research that will characterize work at the nexus of these two fields in the next decade. Finally, I consider possible barriers to such integrative work.


Primary care unit (PCU) is deined as the first holistic healthcare service unit with responses for health promotion, prevention, treatment, and rehabilitation to the family and community. Relevant to diabelic management in PCU, capillary blood glucose is measured with glucometer by skilled professionals and registered paramedical. Although glucometer is gradually increased in clinical care unit, standardization for quality control system is still controversially discussed. The aim of this study was to assess quality control and factors influenced on the assessment of glucometer in 9 PCU at Amphoe Muang Khon Kaen. Forty eight health care professionals were recruited for the study from ctober - November, 008. Two level of low and high commercial control materials were assayed once a week for 6 weeks. All data were analyzed against mean of target value and group value. The results showed quality assessment of the participants met the acceptable threshold of % bias, standard deviation index (SDI), total error (TE), Variance Index Score (VIS), and S compared with target value at 72%, 90%, 66%, 97% and 100%, respectively. Also, the acceptable limit of 65%, 66%, 77%, 97% and 100% compared to group value was observed. Factors influencing quality assessment were identiied by multiple linear regressions. t demonstrated that oicial training for health care professionals influenced TE with low level of control material (r^2 = 0.23, p < 0.001). The results show that quality assessment of the participants is ranged from acceptable to very good in analytical performance. icial training for health care professionals is necessary to decrease magnitude of the error. Also, quality control system for glucometer should be implemented in routinely used in PCU.


Aim: To construct classification scores based on a combination of cancer patient plasma biomarker levels, for predicting progression-free survival. Methods: The approach is based on the optimization of the biomarker cut-off values, which maximize the statistical differences between the groups with values lower or larger than the cut-offs, respectively. An intuitive visualization of the quality of the classification score is also proposed. Results: Even if there are only weak correlations between individual biomarker levels and progression-free survival, scores based on suitably chosen combination of three biomarkers have classification power comparable with the Response Evaluation Criteria in Solid Tumors criteria classification of response to treatments in solid tumors. Conclusion: Our approach has the potential to improve the selection of the patients who will benefit from a given anticancer treatment.


nasty-First Intermediate period in Egypt. The date of ca. 2250/22002000 B. C. for the EB IV-A phase is arrived at on the strength of Egyptian and Mesopotamian chronologies and is in conformity with C-14 assays from Syria. The transition from EB IV-A to EB IV-B at about 2000 B. c. is firmly supported by stratified objects with royal Egyptian names of the early XII Dynasty at Byblos and Ras Shamra, and coincides with the fall of the Third Dynasty of Urr.60 The political events in northern Mesopotamia and inland Syria during the Sargonid-Ur III period on the one hand, and the loss of Egyptian control over Syria and Palestine on the other, would explain the intrusion of the Caliciform culture into coastal Syria and northern Palestine. With the fall of the Third Dynasty of Ur and the rise of the Egyptian XII Dynasty, the Caliciform culture gave way to another, yet related, culture which is represented by Stratum H at Hama in inland Syria, Ugarit Moyen I in coastal Syria, and EB IV-B (Amiran's A group) in Palestine. The latter phase, which is represented by the cemeteries of central and southern Palestine (including the Negev sites) and by residential sites throughout the country (i. e. Beth Shan, Megiddo, Ma'abarot, Lachish, Tell Beit Mirsim, Jericho, Jebel Qa'aqir and Har Yeruham) overlaps at the beginning with the end of EB IV-A, as evident from pottery types common to the C group and some tombs at Jericho. As for the end of the EB IV-B period, it has been suggested elsewhere by the writer that on the basis of the chronology of weapon types in Syria and Palestine the end of EB IV-B and the beginning of MB I (Albright's MB IIA) should be fixed ca. 1900 B. c.61 In any case the thin layer of EB IV-B occupation in Palestine must imply a relatively short life for this phase, between ca. 2000 and 1900 B. C.


In the winter of 2010 Arturo Rigillo has gone, in silence, as he lived, leaving to the family, the friends, the colleagues of the University of Naples Federico II, the international research center LUPT,  the Scientific Committee of the "TRIA" journal, an absence that the memory of his "silent operation" certainly cannot fill it for many who knew him.

Meanwhile, the paper also predicts the tendency of modern distance learning in the futere.


Synopsis: A new technique to manufacture cold rolled ultra high strength steel sheets through the continuous annealing line with a water quenching device has been developed. Full martensite and ferrite plus martensite dual phase steels with 80 to 150 kgf/mm2 in tensile strength can be easily obtained by water quenching after annealing in the austenite and ferrite plus austenite regions, respectively. These products having good formability and weldability are used successfully for automobile parts to improve the safety of the passengers in case of an accident and to reduce the weight of the automobiles. Furthermore, these products are being utilized in the industry of construction, and are expected to be used for machinery, electric appliances, containers, and others.


The setting and hardening process of several concrete and mortar mixtures as well as the influence of concrete additives are monitored by an ultrasonic transmission technique. For the automatic data acquisition and processing of data, the program FreshCon 2.0 was developed under LabVIEW. It can automatically detect signals and calculate the velocity, energy and frequency spectrum, parameters indirectly correlated to the stiffness of the material.

The scattering from impurities in copper is analysed in terms of s, p and d partial waves. The (anisotropic) transition probability between points on the Fermi surface is calculated in terms of scattering phase shifts characterizing the impurity. Maps of the calculated scattering are presented for each phase shift and the corresponding Dingle temperatures are calculated for a variety of orbits seen in the de Haas-van Alphen effect. A procedure developed to calculate the impurity resistivity and anisotropy of the corresponding relaxation time demonstrated the need to use a vector mean free path in such a calculation. The calculated scattering is compared with experimental values in the Cu(Ni), Cu(Fe) and Cu(Al) systems and values derived for the scattering phase shifts.


The aim of this study was to evaluate comparative clinical outcomes of discordant electrocardiographic (ECG) and echocardiographic (Echo) findings compared to concordant findings during treadmill exercise echocardiography in patients with chest pain and no history of coronary artery disease (CAD).

 A total of 1725 consecutive patients who underwent treadmill echocardiography with chest pain and no history of CAD were screened. The patients were classified into four groups: ECG−/Echo− (negative ECG and Echo), ECG+/Echo− (positive ECG and negative Echo), ECG−/Echo+, and ECG+/Echo+. Concomitant CAD was determined using coronary angiography or coronary computed tomography. Major adverse cardiac events (MACEs) were defined as a composite of coronary revascularization, acute myocardial infarction, and death.

 MACEs were similar between ECG−/Echo− and ECG+/Echo− groups. Compared to ECG+/Echo− group, ECG−/Echo+ group had more MACEs [adjusted hazard ratio (HR) adjusted by clinical risk factors (95% confidence interval), 3.57 (1.75–7.29), p<0.001]. Compared with ECG+/Echo+ group, ECG−/Echo+ group had lower prevalence of concomitant CAD and fewer MACEs [HR, 0.49 (0.29–0.81), p=0.006].

 Positive exercise Echo alone during treadmill exercise echocardiography had worse clinical outcomes than positive ECG alone, and the latter had similar outcomes to both negative ECG and Echo. Positive exercise Echo alone also had better clinical outcomes than both positive ECG and Echo. Therefore, exercise Echo findings might be superior for predicting clinical outcomes compared to exercise ECG findings. Additional consideration of ECG findings on positive exercise Echo will also facilitate better prediction of clinical outcomes
