A feeding experiment was conducted to study the effect of different levels of supplemental Prosopis juliflora on growth performance, feed utilization and chemical composition of Nile tilapia (Oreochromis niloticus) fry (1.36 ± 0.04 g). Six isonitrogenous (30.46g 100g -1 crude protein) and isocalorific (0.018 MJ g -1 ) diets were formulated. Diet 1 (control without supplementing P. juliflora), and diets 2, 3, 4, 5 and 6 were supplemented with different levels (20, 40, 60, 80 and 100 g kg -1 ) of P. juliflora, respectively. The results revealed that harvested gain (g fish -1 ) was significantly higher (P≤ 0.05) for fish fed 60g kg -1 P. juliflora, while the lowest value of harvested gain was achieved with fish fed free P. juliflora control diet. Despite that the fish fed diet (4) obtained the highest harvesting weight, weight gain, average daily gain and specific growth rate, no significant differences (P≤ 0.05) were observed in average daily gain (g fish -1 day -1 ) between fish fed diet 3, 4, 5 and 6, and in specific growth rate (% day -1 ) when inclusion level of P. juliflora was increased from 20 to 40 g kg-' in diets 2 and 3 and from 80 to 100g kg -1 in diets 5 and 6, respectively. Feed intake was increased significantly (P< 0.05) with in increasing P. juliflora inclusion level in the experimental diets. No significant differences were observed between the experimental fish groups in FCR in spite of the occurrence of a slight decreasing up to 80g kg -1 , and PER. Protein productive value (PPV g 100g -1 )) and energy utilization (EUg 100g -1 ) were increased significantly (P< 0.05) with increasing P. juliflora inclusion level in the experimental diets up to 60g kg-' and then decreased significantly (P ≤ 0.05). Fish whole body composition of dry matter and protein were significantly (P≤ 0.05) affected by using P. juliflora in fish diets. Fish fed diet 4 achieved the highest values of dry matter and crude protein. The results suggested that diet supplemented with 60g kg -1 P. juliflora improved growth performances, feed and nutrients utilization, and whole body composition (dry matter, protein and energy content) in Nile tilapia fry.


The aim of this study was to isolate lytic phages against Pseudomonas spp. to control the predominant psychrophilic bacterias in raw milk.Ten Pseudomonas spp.strains were isolated from raw milk,and used as hosts, lytic phages were isolated by double- layer plate method from the local sewage. The morphology of the isolated phages was examined by transmission electron. Phage infectivity and stability under different physical and chemical conditions were determined by double- layer plate method. The results showed that three lytic phages ( PP6,PP8 and PP10) were obtained,and phage PP6,PP8,PP10 belonged to the family Leviviridae.Phages PP8 and PP10 showed high infectivity under 4℃ while phage PP6 was most active at 37℃.The optimum pH and NaCl concentrations range for activity of three phages were 5~7 and 1.5% ~5.5% ,respectively.In conclusion,this study is useful for application of phage to control Pseudomonas spp.in raw milk.


Summary points The irritable bowel syndrome affects about 20% of adults in the industrialised world The condition is a disturbance of gastrointestinal function of unknown cause, but abnormalities of intestinal motility and visceral sensation are found in some patients Symptoms of the irritable bowel syndrome are often associated with extraintestinal manifestations, including urinary symptoms, dyspareunia, and fatigue Overall, 40–60% of patients with the irritable bowel syndrome who seek medical advice have psychological symptoms of depression or anxiety, or both Diagnosis of the irritable bowel syndrome can usually be made on the basis of clinical history and examination, but exclusion of organic disease is advisable in patients aged >45 years who present with new bowel symptoms No uniformly successful treatment exists for the irritable bowel syndrome. End organ treatment aimed at relieving abdominal pain (antispasmodic drugs) or disturbed bowel habit (antidiarrhoeal and bulking agents) can produce symptomatic relief, and "central" treatment (for example, anti-depressants, hypnotherapy, psychotherapy) should be considered in patients with associated affective disorders

Silicone oxycarbide (SiOC) is gaining attention as a potential anode material for lithium-ion batteries due to its higher reversible capacity and high-rate capability. However, the employment of SiOC in sodium-ion batteries (SIBs) has remained unclear. Here, the electrochemical performance of SiOC derived from phenyl-rich silicone oil and present with graphene as an anode for SIBs is investigated. 1 M NaClO4 dissolved in propylene carbonate (PC) is used as an electrolyte with and without fluorinated ethylene carbonate (FEC) and its effect on electrochemical performance has been studied. The FEC additive electrolyte shows high electrochemical performance where it delivers high charge capacities of 233, 198, 170, 103, 64, and 32 mA h g−1 compared to 218, 126, 101, 52, 27, and 10 mA h g−1 without additive at current densities of 20, 50, 100, 500, 1000, and 2000 mA g−1, respectively. The sodium diffusion coefficient in a high-performance SiOC anode with an FEC additive electrolyte is calculated to be 1.73 × 10−16 cm2 s−1.


To better understand the process of nanoparticle formation when microspheres are ablated by a high-energy laser pulse, we investigated the Nd:YAG laser-induced breakdown of 20 μm glass microspheres using time-resolved optical shadow images and Schlieren images. Time-resolved imaging showed the location of the initial breakdown and the shockwave motion over its first 300 μm of expansion. From these measurements, we determined the shockwave velocity dependence on laser fluence. Measured shockwave velocities were in the range of 1–10 km/s. We also developed a numerical model that simulated breakdown in the glass microsphere and the propagation of this disturbance through the edge of the sphere where it could launch an air shock. Our objective was to simulate the shockwave velocity dependence on laser fluence and to generate glass density, temperature, and mass velocity profiles after breakdown. The simulation and experimental data compared favorably.


In 1989 the first extortion for currency using a Trojan called AIDS was logged in history, revealing a new threat to data and resources of individuals and organizations, globally known as ransomware. Ransomware is a type of malicious software that has the ability to duplicate itself on a network, affecting devices by locking access to these devices or encrypting data where only the attacker has the decryption key to restore this affected data. This gives the attacker the privilege to demand an amount of money, or a ransom, in order to send the decryption key to the victim, or unlock their device. This paper aims to propose a matrix of measures used to assess the vulnerability of IoT devices or systems to the threat of ransomware, which allows different entities to be prepared for this kind of attack, through shedding the light on ransomware as a major issue threatening today's modern life, from smart cars, smart homes, electronic health records, to planted heart pacemakers; by presenting some previous ransomware attack cases, presenting and discussing some of the current ransomware detection or prevention techniques.


This study offers a set of data concerning the exploration of interrelations between neuropsychological aspects and mathematical scholar difficulties presented by epileptic children. Such children can be characterized by important neuropsychological dysfunctions – attention, memory and visual perception skills – which are related to mathematical impairment concerning the proper use of processual algorithmic tools. Nevertheless, data discussed here show that epileptic children have benefited from the offer of semiotic aids from culture, which highlights the need for considering the context of culture in the neuropsychology of learning in a broad sense, including the specific case of mathematics activity at school.


The use of teacher lesson plans as a tool to measure program effectiveness was explored as a part of an overall evaluation of a gifted program in grades 1 to 6. A Lesson Plan Evaluation Form (LPEF) was developed to provide systematic quantitative data about classroom functioning that are usually obtained only through attitudinal surveys. One hundred thirty-seven plans from 15 teachers were analyzed. The lesson plan analysis yielded useful information about program functioning in a cost-effective manner. Data from the LPEF were consistent with data from more traditional evaluation tools. The use of lesson plan analysis as a tool to measure program effectiveness should be further investigated.


Purpose. The new metastable phases (including amorphous state), that are characterised unique physical properties, can be obtained by the quenching from the melt. The practical use of amorphous materials is restricted by the thermal interval of amorphous state stability. Study of influence of cooling rate on the films structure, as well as the effect of thermal treatments on the phase transformations occurred in solid states are very important. Methodology. The structure details of initial and treated films are determined by means of X-ray diffraction and metallographic methods. Magnetic properties were investigated by the vibration magnetometer. Findings. It has been found, that the change from crystalline structure (mixture of phases р-Со(В) и (Co,Si>B) to amorphous one is observed in Co67.2Fe6.1Ni10Si11B15.9 films with increase of cooling rate from 104 K/s to 106 K/s. Size of the coherently diffracting domains was approx. 2 nm. The structure change and formation of amorphous phase leads to the drastic decrease of initial films coercivity from 4000 A/m to 80 A/m. The crystallisation of amorphous films occurs in temperature range 480 - 510 оС (5 min). In the first stage, only primary р-Со(В) crystals appears in residual amorphous matrix. The annealing at the temperature 550 оС (5 min) leads to the decomposition of residual amorphous phase. In the second one, metastable phase (Co,Si)3B (structure type Fe3C) is formed. Coercivity of treated films increased to 24 000 A/m. It connected with crystallisation processes and the formation of multiphase structure. The annealing under tensile stress in this temperature interval 480 - 570 oC (5 min) did not alter the films structure. Size of the coherently diffracting domains increased up to 3 nm. Coercivity of treated films under tensile stress was 80 A/m. Originality. Annealing under tensile stress increased the thermal stability of amorphous phase. The crystallisation processes begins at temperature up to 570 oC, that expands the thermal interval stability of amorphous phase on 80-100 oC. It is possible that stress annealing stimulates the processes of amorphous phase separation into two phase with different short order and following formation of the phase mixture (Р-Со(В) и (Co,Si)3B) through eutectic crystallization. Practical value. Increase the thermal interval stability of amorphous phase will expand practical use in devices and precized apparatures.


Simultaneous determination of medication components in pharmaceutical
samples using ordinary methods have some difficulties and therefore these determinations usually
were made by expensive methods and instruments. Chemometric methods are an effective way to
analyze several components simultaneously.

 In this paper, a novel approach based on Bayesian regularized artificial neural network
is developed for the determination of Loratadine, Naproxen, and Diclofenac in water using UV-Vis
spectroscopy.

A dataset is collected by performing several chemical experiments and recording the UV-Vis
spectra and actual constituent values. The effect of a different number of neurons in the hidden
layer was analyzed based on final mean square error, and the optimum number was selected. Principle
Component Analysis (PCA) was also applied to the data. Other back-propagation methods,
such as Levenberg-Marquardt, scaled conjugate gradient, and resilient backpropagation, were tested.

In order to see the proposed network performance, it was performed on two crossvalidation
methods, namely partitioning data into train and test parts, and leave-one-out technique.
Mean square errors between expected results and predicted ones implied that the proposed method
has a strong ability in predicting the expected values.

he results showed that the Bayesian regularization algorithm has the best performance
among other methods for simultaneous determination of Loratadine, Naproxen, and Diclofenac
in water samples.


In this paper, we investigate the fundamental limits of sensor network lifetime that any algorithm can achieve. In our settings, n nodes are deployed as a Poisson point process with density lambda in a region of size S and each sensor node can cover a unit-area disk. For any k and lambda, let V(k, lambda) be the random variable (r.v.) of the size of the region that is covered by at most k - 1 nodes. Under these assumptions, we first show that for any function omega satisfying 1 Gtomega (k) Lt k1/2 the r.v. V(k, k- omega(k)k1/2) converges almost surely to S. In contrast, if the intensity is set to lambda = k + omega(k)k1/2 we obtain that V(k, k +omega(k)k 1/2) converges almost surely to 0. These limit theorems extend the results of Zhang and Hou in [21], [22] where the authors worked with fixed degree of coverage (k = O(1)) and lambda = log S+O(k) log log S. Assume that each sensor has the same lifetime T. As consequences of our analytical results, we derive randomized algorithms (working with high probability) that can maintain constantly high degrees of coverage while prolonging the lifetime of the network.


In the paper we consider the possibilities of complex approach to the design of machine tools in the light of the newest means which the designer can use on the earlier stages of the design procedure. Same of components is delivered with the controllers in the form of the microprocessors. In that case it is useful to change nominal software to adjust the control law to our purposes. So more we can add additional control loops to improve dynamics of the machine


An innovative technique for the biasing of power amplifiers (PAs) is presented that allows reduction of the DC power consumption, especially when the PA is operated at mid/low output power, without compromising the linearity at high output power level. The fully integrated adaptive biasing circuit, in 0.5 /spl mu/m BICMOS technology, senses the operating PA power and adjusts its quiescent current accordingly. The method is applied to a UMTS PA, resulting in a power consumption saving of about 70% when compared to conventional biasing solutions.


The aim of our study is to develop a fig vinegar, fillowing the evolution of physicochemical (pH, acidity, sugar content and phenol compounds) and microbiological (total aerobic microorganisms and fungi) parameters, during 40 days. At the end, our product was subjected to a hedonic analysis. Two varieties of figs used (Azendjar and Taamriwth, dry and fresh) were grown and provided by the cooperative of the fig of Beni Maouche (COOPFI). The results of the physico-chemical parameters showed a decrease in pH, sugar concentration, and phenol compounds during the whole process (double fermentation), whereas acidity increased. Microbiological analysis showed a gradual and significant reduction in the bacterial and fungal microflora. The hedonic test showed a greater appreciation for the dry fig-based vinegar in comparison to the vinegar produced with fresh fig. It appears, there are many valorization possibilities of regional and national figs, vinegar production is one of them.


Potentialities of discriminating water motions and admixture transfer patterns within the surface layer and underlying thickness of the sea from the estimates of spectral-different normalized radiances are demonstrated by the example of the ocean color scanners data for the Black and Baltic Seas. The merits and limitations of the approach are discussed.


Abstract In the southern Argentine Andes, ten advances of valley glaciers were used to reconstruct the late-glacial and Holocene glacier history. The accumulation areas of these glaciers lie in the Precordillera and are thus independent of fluctuations of the South Patagonian Icefield. Like the Viedma outlet glacier, the valley glaciers advanced three times during late-glacial time (14,000–10,000 yr B.P.). The youngest advance correlates with the Younger Dryas Stade, based on two minimum AMS14C dates of 9588 and 9482 yr B.P. The second oldest advance occurred before 11,800 yr B.P. During the first half of the Holocene, (ca. 10,000–5000 yr B.P.), advances culminated about 8500, 8000–7500, and 5800–5500 yr B.P. During the second half of the Holocene, advances occurred between ca. 4500 and 4200 yr B.P., as well as between 3600 and 3300 yr B.P. In the Rı́o Cóndor valley three subsequent advances have been identified.


A cerebellar model articulation controller (CMAC) neural network based scheme for controlling a nonlinear mechanical system that incorporates hydraulic actuator dynamics is proposed. This control scheme is shown to perform well in the presence of nonlinearities due to fluid flow, oil compressibility, leakages and static friction. Further, the algorithms developed are shown to effectively track different trajectories and reject disturbances while compensating uncertain dynamics present in the hydro-mechanical system. This control scheme also shows that it can cope with complexities associated with a highly nonlinear hydraulic system, which is more desirable than conventional control schemes that are typically designed using linearised models.


The process of qualitative coding often involves multiple coders coding the same data to ensure reliable codes and a consistent understanding of the codebook. One aspect of qualitative coding includes resolving disagreements, where coders discuss differences in coding to reach a consensus. We conduct a case study to evaluate four strategies of disagreement resolution and understand their impact on the coding process. We find that an open discussion and the n-ary tree metric lead coders to focus more on the disagreement of a particular data instance, whereas kappa values and Code Wizard direct coders to compare code definitions. We discuss opportunities for using different strategies at different stages of the coding process for more effective disagreement resolution.

"Living" anionic polymerizations carried out in a continuous stirred-tank reactor (CSTR) and operated under forced-feed oscillations are theoretically studied to investigate the effects on time average values of average chain lengths, polydispersity, and reagent conversions. The instantaneous mean residence time is maintained constant. The period of the oscillations is varied between 60 and 0.05 mean residence times, and various amplitudes are considered. Some advantages are observed with the periodic forcing as compared to the steady operation; polymers with average polydispersities above 10 may be produced at low frequencies, with polydispersities below the steady-state value of 2 at intermediate frequencies, and with polydispersities of 2 but with increased monomer conversion at fast cycling.


Precise and accurate estimation of state vectors is an important process during position determination. In this study, Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) of stationary user, state vectors defined in Earth Centered Inertial (ECI) coordinate system, accompanied by GNSS measurement data. It is aimed to make estimations with methods. EKF and UKF methods were compared with each other. In this study, the effects of nonlinear motion analysis and linearization methods on state vector estimations were investigated. Thanks to this study, estimations of the positioning information required during the specific tasks of many moving platforms have been made.


Although a great progress has been achieved for the development of NF membranes and technologies and SRNF do show a great potential in the separation of organic components, an NF membrane with good separation performance and good resistance to organic solvents are urgently needed for a more complicated situation in practical. In this study, a kind of solvent-resistant nanofiltration (SRNF) membrane was fabricated via interfacial polymerization on a laboratory optimized cellulose acetate (CA) basic membrane. The effects of interfacial polymerization parameters, such as water phase concentration, immersed time in the water phase and in the organic phase, on the pure water flux and rejection rate of C-2R yellow dyestuffs were investigated. A highest dye rejection rate of 72.9% could be obtained by water phase solution containing 1% m-xylylenediamine (mXDA) and organic phase solution with 0.2% trimesoyl chloride (TMC) under immersed time in water phase of 6 minutes and in organic phase of 40 seconds. This membrane demonstrated better resistance to methyl alcohol compared to commercial membrane. This study may offer an avenue to develop a solvent-resistant nanofiltration membrane.


Soil pollution as a result of intensive exploitation by mining companies creates a serious problem for animal health, obtaining environmentally friendly products. Among the metals that are classified as heavy, there are elements that adversely affect the body of humans and animals, inhibiting enzymatic activity, and having cumulation properties, up to toxic indicators, resulting in large-scale functional disorders. Livestock products contaminated with heavy metals also cause pathologies in humans, leading to respiratory, nervous, oncological and other diseases. Soil remediation costs are very expensive. Recently, bioremediation and phytoremediation have become innovative, cost-effective and safe methods of soil recovery from heavy metals. A combination of these methods has been adopted as a synergistic tool for soil restoration. The priority is the search for effective bacteria that promote plant growth, which serve as a biofertilizer, a bioremediation microbe, and also have endophytic properties. This helps metal-absorbing bacteria enter the plant and these plants can be easily uprooted to remove most heavy metal contaminants. The endophytic properties of microbes are selective depending on the host plant. To study the endophytic properties, we used the microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48. Fagopyrum esculentum was treated with strains of microorganisms Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48, which exhibit endophytic properties on LB medium. The strain Microbacterium oxydans ZB11 showed endophytic activity on the root and stem. Paeniglutamicibacter sulfureus ZB48 showed endophytic activity on roots and stems 4 cm above the basal stem, showing good endophytic activity compared to Microbacterium oxydans ZB11. We report the endophytic properties of Microbacterium oxydans ZB11 and Paeniglutamicibacter sulfureus ZB48 on buckwheat (Fagopyrum esculentum). Fagopyrum esculentum is known as a good plant for phytoremediation.


Objectives This study was to assess the mid-term results of the one-and-a-half ventricular repair (hemi-Mustard and bidirectional Glenn procedures combined with the Rastelli procedure) and Fontan pathway for correcting congenitally corrected transposition of great artery (ccTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malposition. Methods In this retrospective study, 74 consecutive ccTGA with LVOTO and cardiac malposition underwent the one-and-a-half ventricular repair (group A; 33 cases) and Fontan operation (group B; 41 cases) between October 2011 and March 2018. The Median follow-up time was 49 (20–84) and 42 (7–85) months in groups A and B, respectively. To estimate excise tolerance the 6-min walk test (MWT) was performed. Results No in-hospital death. Compared with group A, group B have significantly less CPB, mechanical ventilation time, and intensive care unit stay, but prolonged pleural effusions developed more frequently in Group B. The survival probability was 90.2% (95% CI, 80.2–100%) and 97.2% (95% CI, 92–100%) at 7 years (p = 0.300) in group A and B. The probability of freedom from re-intervention were 80.6% (95% CI, 66.5–97.6%) and 97.2% (95% CI, 92–100%) at 7 years (p = 0.110). Longitudinal repeated measured echo data at every follow-up time shows that group A has more systemic ventricular EF% (p < 0.001) and less moderate systemic ventricular valve regurgitation (p < 0.001) compared with group B. Estimated by 6 MWT, group A has better outcomes for 6-min walk distance. Conclusions For correction of ccTGA with LVOTO and cardiac malposition, the one-and-a-half ventricular repair had superior midterm heart function and excise tolerance.


1. The species-area relationship is considered amongst the few genuine laws in ecology. Although positive species richness-stone area relationships have been found previously in stream systems, very few studies have simultaneously examined species-individuals, individuals-area, species-bryophyte biomass and individuals-bryophyte biomass relationships. We examined these relationships based on temporally replicated assessments of macroinvertebrates on stones at two river sites. 2. We found only one significant species-area relationship out of six relationship tested, and two significant individuals-area relationships. Even these significant relationships were weak, however. By contrast, we detected significant and rather strong relationships between species richness and the number of individuals at both river sites on all three sampling dates. We also found significant relationships of both species richness and the number of individuals with bryophyte biomass at both river sites on all sampling occasions. One of the river sites was disturbed by a bulldozer, and the species-bryophyte biomass relationships were somewhat stronger after the disturbance event. 3. Our findings are quite surprising, given that there were very weak species-area relationships on stream stones. By contrast, our results suggest a pivotal role for bryophyte biomass in determining the species richness and the number of individuals of stream macroinvertebrates at this small scale. The most probably origin of these relationships begins with bryophyte cover, which determines the number of individuals, and subsequently passively affects species richness. Thus, there is not necessarily a direct mechanism that determines the variability of species richness on stream stones. 4. Experimental studies are needed to disentangle the various mechanisms (e.g. passive sampling, provision of more food, more niche space, flood disturbance refugia) by which bryophyte biomass affects stream macroinvertebrates.


AlN films were deposited on Si (1 1 1) substrates by middle-frequency magnetron sputtering with and without anode-layer ion source assistance, and stoichiometric films were obtained. The structure and composition of the films were characterized by x-ray diffraction, atomic force microscopy and scanning electron microscopy. The films deposited under optimal conditions have strong diffraction of AlN (0 0 2) and a relatively weak diffraction of AlN (1 0 0), and the full width at half maximum of (0 0 2) peaks of these films falls in the range of 612–648 arcsec. The effect of the anode-layer ion source on the AlN film growth is discussed.


The time-preference model of intergenerational tradeoffs posits an intergenerational time preference, in which the utility of future welfare is discounted with time. When separated from confounds with the use of thought experiments, the time-preference model predicts widespread arbitrariness and implausible or even absurd reactions to tradeoffs. In contrast, social preferences explain both diminished concern for future generations and for socially-distance contemporaries. Regardless of what is useful for economic decision making, the social-preference model is an improvement on the time-preference model for the purposes of debating the justifiability of discounting future welfare and for motivating people to care more about future people. For these purposes, it is best to assume the most charitable interpretation available that is consistent with the evidence.


The applicability of organizational design (OD) to the Asian context is illustrated by data that were collected from a sample of 49 companies in Singapore. The results show that only large and established organizations seem to have OD programs. Furthermore, the data indicate that behavioral changes form the major part of OD programs. The top-down approach is common in introducing change through OD efforts. A major barrier to the practice of OD in many Asian countries seems to be lack of climate for open discussion.


In order to improve the fault-tolerant and dynamic optimization capability of the information fusion method for multisensor system,the theory of dynamic Bayesian networks is used to rebuild the conventional federated Kalman filter.And a kind of active and dynamic information fusion and optimization method for multisensor systems under high dynamic situation is proposed.The simulation results show the high dynamic flexibility and fault-tolerant ability of the proposed method.


Subtotal colectomy has been performed in 40 patients with severe constipation. Only one patient was male. Five patients (13 per cent) had a history of a serious psychiatric disorder. Twenty‐six patients (65 per cent) could not expel a 100‐ml air‐filled balloon and 19 patients (48 per cent) had electromyographic evidence of abnormal puborectalls contraction during attempted defaecation before operation. Median preoperative passage of 50 radio‐opaque markers over 5 days was 16 per cent. Sixteen patients had had a previous anorectal myectomy to exclude Hirschsprung's disease. Initial resections were subtotal colectomy and ileorectal anastomosis (n = 34), caecorectal (n = 5) or ileosigmoid (n = 1) anastomosis. Secondary operations included restorative proctocolectomy and ileal pouch—anal anastomosis (n = 6) and six patients eventually had an ileostomy. Median bowel frequency per week significantly increased after operation (0·3 (range 0–1) preoperatively to 21 (range 2–70) postoperatively, P < 0·005), the percentage of patients with abdominal pain fell after operation from 93 to 39 per cent but symptoms of abdominal distension remained the same (86 per cent preoperatively and 82 per cent postoperatively).


The potential for production of microbiologically stable apple juice by metallic membrane ultrafiltration was assessed. Thermal sterilization treatments caused no detectable changes in membrane performance. Sterile membranes were challenged with approximately 3 × 106 colony forming units per gram of each of three organisms, Pseudomonas diminuta, Bacillus coagulans, and Saccharomyces cerevisiae, suspended in apple puree or peptone. Reductions achieved by ultrafiltration of peptone at operating pressure were 5.1, 7.6, and >9.0 logs for the three organisms, respectively. Reductions of organisms in apple puree were at least 1.5 logs greater. Metallic membranes eliminated yeasts and molds from juice. Apple juice produced from uninoculated apple puree was stable at 20–25°C for 1 yr.


The relationship between vertical motion at the top of the boundary layer, geostrophic vorticity in the boundary layer and divergence in the boundary layer are examined in this study. The equation of motion and the continuity equation are applied to a homogeneous barotropic atmosphere using a numerical model in this study. The solutions reveal that the boundary layer is stable for very large values of Ro in the case of positive vorticity and becomes unstable at Ro = 1 .0 in the case of negative vorticity. A difference in behavior is found between cases of anticyclonic and cyclonic shear. The magnitude of the vertical velocity is greater and the boundary is thicker for anticyclonic than for cyclonic shear systems of equivalent strength.


evidence obtained by the use of the polygraph, although eventually it might be of value, should not be accepted until further experience of its limitations had been gained. In a more recent case (People v. Kenney, 1938) a trial court of New York State allowed evidence based on lie-detector tests to be given, but in the same year the New York Court of Appeal refused to accept such evidence in a murder trial (People v. Forte). So far, therefore, there have been three Appeal Court decisions in which the results of lie-detector tests have not been accepted. These decisions are in accord with the well-known limitations of the tests. Under the most favourable conditions there is a possible error ofat least 10% in the results, and a further 20% of persons tested give indecisive results, so that there would always be some risk of injustice being done, even when the operator of the instrument was thoroughly experienced and free from any bias. A question of more immediate practical importance is that of the admissibility of a confession following the application of lie-detector tests. This point was raised in 1939 before the Supreme Court of Pennsylvania (Commonwealth v. Hepple) in a murder trial. The defence objected to the confession being admitted in evidence because it had been made after the application of lie-detector tests. The defendant had been told that he could not lie to the machine, and the attorney for the defence took exception to this statement having been made, but the Court held that as no promise or threat had been made to extort the confession, it was admissible in evidence. When confessions resulting from lie-detector tests are brought before a court it is frequently contended by the defence that they have been obtained by "third degree" methods, although it is claimed that little, if any, bodily discomfort is produced by the tests. To meet this objection, the prosecution may' call the lie-detector operator to give evidence that the confession was made to him, and omit all reference to the tests which preceded the confession. This leaves it open to the attorney for the defence to introduce the lie-detector issue for the purpose of contending that it was a torture device. Even if the test causes insignificant bodily discomfort, it may have a pronounced mental effect especially on highly nervous subjects, and in the hands of an incompetent operator may very well lead to erroneous deductions. It seems improbable that public opinion in this country would acquiesce in such an instrument of interrogation being placed in the hands of the police or that confessions obtained by that or any analogous method would be admissible in our Courts.


Thin films of light-emitting polymers might one day form the basis of large, low-cost, lightweight, flexible luminescent displays for computers, televisions, and other devices. But progress toward these applications has been slow because thin films of perhaps the most promising family of light-emitting polymers—poly( p -phenylene vinylene) (PPV) and its derivatives—aren't easy to prepare. The polymers generally are highly insoluble and thus difficult to process, explains polymer chemist Bing R. Hsieh of Xerox Corp.'s Wilson Center for Technology in Webster, N.Y. Most of the conjugated polymers that have been reported are available in only milligram quantities because the monomers also are hard to make in larger amounts, he adds. Hsieh and his collaborators now have developed simple, routine synthetic methods for preparing a wide range of monomers and soluble PPV derivatives in multigram quantities. "By overcoming both the processibility and availability issues in PPV," he tells C&EN, "we are in an excelle...


Nowadays socio-economic development of countries and regions is characterized by changing of emphasis. Thus, this raises the question about adequacy of traditional measurement methods for evaluation of the socio-economic development results. The task of development and implementation more relevant indicators and evaluation methods has increasing importance. The authors suggesttheir view of the stated problem and approach to evaluation of socio-economic development results of the territories. This approach is based on consideration sustainability, inclusiveness and innovation aspects. Composition of indicators which is appropriate to usefor evaluating the degree of harmonious socio-economic development is substantiated by the authors. The feasibility of using factor analysis based on principal components method for calculating the compositional harmonious development index is substantiated in the publication. The index for Russian regions is calculating using stated method for control years chosen from the period 2000-2019. Rankings are constructed based on index values. The main characteristics of the regions determining the degree of harmonious development is identified based on the results. The results of the research are aimed at improvinganalysis abilities, the evaluating methods of socio-economic development of the territories and providing rationale for state economic and regional policy.


A power upgrade from nominal power to 105% was concluded in 1999 for the two BWR reactors of Laguna Verde. The current activities for the expansion of nuclear power in Mexico include an Extended Power Uprate from 105% to 120% nominal capacity. Long term plans include operational license extension of the two reactors for a total of 60 years. Although there are not government official plans to build new Nuclear Power Plants in Mexico; studies about technical and economical feasibility of new nuclear capacity are being carried out by the Mexican Utility CFE and the Mexican Nuclear Research Institute. These studies establish a medium term proposal which includes the construction of eight new reactors. In the official electricity program the Mexican government has stated to install 17,942 MWe by 2018 of new electricity capacity, of this amount 15,574 MWe will be generated using conventional sources and 2,368 MWe will be defined in the future, using other technologies that could include nuclear power.


Given the resources needed to launch a retail store on the Internet or change an existing online storefront design, it is important to allocate product development resources to interface features that actually improve store traffic and sales. Using a regression model, we predict store traffic and dollar sales as a function of interface design features such as number of links into the store, image sizes, number of products, and store navigation features. By quantifying the benefits of user interface features, we hope to facilitate the process of designing and evaluating alternative storefronts by identifying those features with the greatest impact on traffic and sales.


Abstract : This report reviews the recent literature on computer-driven information display techniques that have potential applications to military and commercial aircraft. An attempt was made to include survey documents or documents with broad descriptive content rather than an intensive analysis of a narrow aspect of a topic. With few exceptions, documents were limited to those published since 1965. Major display techniques reviewed include cathode ray tubes, electroluminescent displays, light-emitting diodes, and liquid crystal displays. Recommendations for an expanded follow-on research and development program are outlined. (Author)


Objectives: The purpose of this study was to evaluate the effects of incremental dental care(IDC) program on kindergarten children. Methods: The subjects were 46 kindergarten children aged 6 who wished participation in IDC program during 5 weeks at oral health center in G-college from March to May, 2012. The data of subjects were examined into oral conditions such as toothbrushing method and frequency, modified O`leary plaque index and dental caries activity before and after IDC program. The collected data were analyzed by SPSS statistical package version 19.0. Results: 1. The rolling and fones methods of toothbrushing increased from 10.8% to 91.3% after IDC program(p<.001). The change of toothbrushing frequency showed that over 3 times a day increased from 52.2% to 76.0% after IDC program(p<.01). 2. The modified O`leary plaque index of before toothbrushing education increased from 1st visit(score 32.19) to 5th visit(score 57.14) and after toothbrushing education increased from 1st visit(score 64.45) to 5th visit(score 78.27) during IDC program(p<.001). 3. As a results of dental caries activity test before and after IDC program, it was found that the bacterial numbers in S.mutans and Latobacillus reduced from 0.74, 0.70 to 0.28, 0.41 (p<.01) and the saliva buffering capacity increased from 1.50 to 2.02(p<.001). Conclusions: It is considered very necessary that IDC program should be maintained and extended to dental clinic so as to enhance the oral health state of kindergarten children.


This paper reports the theoretically investigated aerodynamic imbalance of the propeller blade, as well as correcting masses for balancing it.
It has been established that the aerodynamic forces acting on the propeller blade can be balanced by the adjustment of masses. This is also true for the case of compressed air (gas) provided that the blades are streamlined by laminar flow. That makes it possible to use rotor balancing methods to study the aerodynamic forces acting on the propeller blade.
The rotating blade mainly generates torque aerodynamic imbalance due to a lift force. A much smaller static component of the aerodynamic imbalance is formed by the drag force acting on the blade. The correcting mass located in the propeller plane balances both static and torque components of the aerodynamic imbalance in its correction plane. A second correcting mass (for example, on the electric motor shank) balances the torque component of aerodynamic imbalance in its correction plane.
The calculations are simplified under the assumption that the equilibrium of aerodynamic forces is perpendicular to the chord of the blade. For approximate calculations, one can use information about the approximate location of the pressure center.
The aerodynamic forces acting on the blade can be determined on the basis of the correcting masses that balance them. The accuracy in determining the aerodynamic forces could be improved by measuring a lift force.
The computational experiment has confirmed the theoretical results formulated above. The experiment further proves the possibility of applying the devised theory for propellers whose rotation speed changes with a change in the angles of blade installation.
The findings reported here could be used both for devising methods of propeller balancing and for constructing methods to study the aerodynamic forces acting on the blade.


We consider the origin of the time-frequency structure of Jovian narrowband decametric radio emission as a consequence of propagation of radiation in the Jovian ionosphere with time varied parameters. Our laboratory and numerical experiments show that the time-frequency structure of dynamic spectra of an initially continuous signal can drastically vary as functions of the form of the magnetic field disturbance in the media where the radiation propagates. Structures similar to those observed in the real experiments, ranging from NB emission and quasiperiodic trains of S bursts to more complex structures, arise in the dynamic spectrum. Assuming the formation of the time-frequency structure of the Jovian narrowband decametric radio emission as a result of propagation of the radiation in the ionosphere and lower magnetosphere of the planet we can get the information about the conditions in the Jovian ionosphere and low magnetosphere.


The wide spread of coronavirus disease 2019 (COVID-19) has become a global concern and millions of people have been infected. Chest Computed Tomography (CT) imaging is important for screening and diagnosis of this disease, where segmentation of the lung infections plays a critical role for quantitative assessment of the disease progression. Currently, 3D Convolutional Neural Networks (CNNs) have achieved state-of-the-art performance for automatic medical image segmentation tasks. However, most 3D segmentation CNNs have a large set of parameters and huge floating point operations (FLOPs), causing high command for equipments. In this work, we propose LCOV-Net, a lightweight 3D CNN for accurate segmentation of COVID-19 pneumonia lesions from CT volumes. The core component of LCOV-Net is a lightweight attention-based convolutional block (LACB), which consists of a spatiotemporal separable convolution branch to reduce parameters and a lightweight feature calibration branch to improve the learning ability. We combined our LACB module with 3D U-Net as LCOV-Net, and tested our method on a dataset of CT scans of 130 COVID-19 patients for the infection lesion segmentation. Experimental results show that: (1) our LCOV-Net outperforms existing lightweight networks for 3D segmentation and (2) compared with the widely used 3D U-Net, our LCOV-Net improved the Dice score by around 20.36% and reduced the parameter number by 90.16%, leading to 27.93% speedup. Models and code are available at https://github.com/afeizqf/LCOVNet.


Abstract : The objective of this program was to develop flexible foam systems which would meet the specifications outlined in MIL-F-81334B(AS). This report deals with the results obtained from a series of one-shot polyether foams derived from mixtures of poly(oxytetramethylene) glycol, poly(oxypropylene) and ethylene oxide terminated poly(oxypropylene) polyols. Polyol ratios, surfactant type, surfactant concentration and stannous octoate/tert-amine ratios were studied to determine their influence on foam properties. Properties such as density, compressibility, rebound, tensile strength, elongation, hydraulic fluid resistance, porosity and vibration damping were obtained on the most promising systems.


AbstractA method is presented for estimating bathymetry in a river, based on observations of depth-averaged velocity during steady flow. The estimator minimizes a cost function that combines known information in the form of a prior estimate and measured data (including measurement noise). State augmentation is used to relate the measured variable (velocity) to the unknown parameter (bathymetry). Specifically, the unknown consists of deviations in depth about a known along-channel mean. Verification of the method is performed using a simple 1D channel geometry as well as for two real-world reaches. In all cases, the verification is based on nominal river depths of 3–10 m, channel widths of 50–100 m, and Froude numbers much less than one. Further tests are performed to assess the usefulness of various observation types and sampling schemes for this type of estimation.


Stepping out of Aldgate East station, one is immediately overwhelmed by the implosion of new towers on every corner; the briefest of London sun bouncing off the shiny metal and glass surfaces. It is here that we begin our fieldtrip— for the study of class cannot be contained in the classroom. Recognising that the spatial and the social are innately intertwined, we see class distinctions inscribed into the very architecture of a city.


Ionization profile monitors (IPMs) are used in the Fermilab Main Injector (MI) to monitor injection lattice matching by measuring turn-by-turn sigmas at injection and to measure transverse emittance of the beam during the acceleration cycle. The IPMs provide a periodic, nondestructive means of performing turn-by-turn emittance measurements where other techniques are not applicable. As Fermilab is refocusing its attention on the intensity frontier, non-intercepting diagnostics such as IPMs are expected to become even more important. This paper gives an overview of the operational use of IPMs for emittance measurements and injection lattice matching measurements at Fermilab, and summarizes the future plans.


In the modern day of transport, the traffic light is important to safety on the road. However, not all traffic lights are built safely, and are subject to malfunctioning. With the use of formal methods, systems can be designed to be faultless in deployment. With the use of Event-B, a common formal method for formal modelling and the assistance of Rodin, a tool for Event-B, a traffic light system model was designed with safety and functionality in mind. The system focuses on a T-junction model of Sunway City, Selangor, which is a smart city in Malaysia, as it does not have a formally proven traffic light system, which could lead to incidents or accidents that may be fatal. The Event-B model has been formally specified by Rodin and verified by theorem provers. Some aspects were simulated to showcase the flow of traffic through the day. Results show that the model functions without error.


This paper introduces the artificial emotional creature project that seeks to explore a different direction that is not so rigidly dependent on such objective measures as accuracy and speed. The goal of this project is to explore a new area in robotics, with an emphasis on human-machine interaction. There is a large body of evidence that shows the importance of the interaction between humans and animals such as pets. We have been building a pet robot, as an implementation of an artificial emotional creature, with the subjective appearance of "behaviors" that are dependent on internal states as well as external stimulation from both the physical environment and human beings. The pet robot has visual, auditory, and tactile sensors. This paper discusses the emergence of intelligence by non-verbal communication between human and robot through physical interaction.


Objectives: This study was designed to evaluate and compare the effect of two commercially available casein phosphopeptide amorphous calcium phosphate preparations applied with or without stannous fluoride gel in the prevention and treatment of early enamel decalcification. Materials and methods: The material consisted of eighty freshly extracted premolars which were divided into 8 equal groups of 10 each. Four groups were used to evaluate the effectiveness of Tooth Mousse, Tooth Mousse combined with stannous fluoride gel and Topacal C-5 combined with stannous fluoride gel in the prevention of enamel demineralization around orthodontic brackets, using polarized light microscope. The other four groups were used to evaluate the effect of the same three techniques in the treatment of artificially induced white spot lesions, using stereomicroscopic imaging. Results: The teeth in the control group had the deepest lesions followed by the Tooth Mousse then the two combination groups. Similarly teeth which showed an improvement in the severity of the white spot lesions from the baseline scoring were only in the Professor, Department of Orthodontics, Faculty of Dentistry, Alexandria University. Assistant Professor, Department of Oral Pathology, Faculty of Dentistry, Alexandria University. 3 Graduate Student, Department of Orthodontics, Faculty of Dentistry, Alexandria University. Egyptian Orthodontic Journal 2 Volume 36 – December 2009 test groups and the complete healing was only in the two combination groups, while worsening of white spots to white spots with cavitation was mainly seen in the control group. Conclusions: The three tested techniques proved to be able to reduce the rate of enamel demineralization around orthodontic brackets when compared with the control (no treatment). The three tested techniques proved to be able to treat the white spot lesions to a limited extent and to prevent their worsening into cavitations when compared with the control (no treatment). There were no statistically significant differences between the effects of the tested techniques neither in the prevention of enamel demineralization nor in the treatment of the white spot lesions.


Over the past few years, macromolecular structures have been successfully solved from Electron diffraction(ED) patterns using standard macromolecular X-ray crystallographic(MX) techniques[1]. This resulted in the emergence of a new field known as microED. MicroED is a very appealing technique as it allows for solving structures from nanocrystals thanks to the very strong electron-atom interaction. This is of great interest especially in protein crystallography where growing good quality macromolecular crystals up to micrometer sizes is often a challenge.

Over the past few decades, fast-growth has occurred in the area of medical image acquisition devices, and physicians now rely on the utilization of medical images for the diagnosis, treatment plans, and surgical guidance. Researchers have classified medical images according to two structures: anatomical and functional structures. Due to this classification, the data obtained from two or more images of the same object frequently provide complementary and more abundant information through a process known as multimodal medical model registration. Image registration is spatially mapping the coordinate system of the two images obtained from a different viewpoint and utilizing various sensors. Several automatic multimodal medical image registration algorithms have been introduced based on types of medical images and their applications to increase the reliability, robustness, and accuracy. Due to the diversity in imaging and the different demands for applications, there is no single registration algorithm that can do that. This paper introduces a novel method for developing a multimodal medical image registration system that can select the most accepted registration algorithm from a group of registration algorithms for a variety of input datasets. The method described here is based on a machine learning technique that selects the most promising candidate. Several experiments have been conducted, and the results reveal that the novel approach leads to considerably faster reliability, accuracy, and more robustness registration algorithm selection.

Abstract. The purpose of this study was to determine the increase in the entrepreneurial competence of school principals in the Kusuma Bangsa Cluster, Sawangan District, Magelang District, Odd Semester, 2018/2019 Academic Year through the guidance of school supervisors. This type of research is a study that uses a school action research (PTS) design with a qualitative approach. The subjects of this study were 10 school principals in the Kusuma Bangsa Cluster, Sawangan District, Magelang Regency. The main data were obtained from the class teacher. Data collection methods by interview, observation, and documentation methods. The results of this research were able to improve the entrepreneurial competence of school principals in the Kusuma Bangsa Cluster, Sawangan District, Magelang Regency, both in quality and quantity. Before giving action in the form of school supervisor coaching, the entrepreneurial competence of the School Principal in the Kusuma Bangsa Cluster, Sawangan District, Magelang District only reached a percentage of 60.50% (there were 4 Principals in the poor category, 5 Principals in the good category and 1 School Principal included in the very good category), after being given the action there was an increase in cycle I of 70.50% (there were 2 Principals in the poor category, 6 Principals were in the good category and 2 Principals were in the very good category) and in cycle II increased to 81.50% (there were 5 Principals in the good category and 5 Principals in the very good category).


(tert-Butylimino)(2,2,6,6-tetramethylpiperidino)borane (1) is a highly reactive species. Its B≡N triple bond inserts into the B−H bond of boranes, R2BH, generating diborylamines of the type tmp−BH−NtBu−BR2 (tmp = 2,2,6,6-tetramethylpiperidino; R = H, Cl, Br, or organyl). Thexylborane reacts analogously, but only one of its two B−H bonds is used for the hydroboration of 1. However, dihaloboranes HB(Hal)2−SMe2 (Hal = Cl, Br) give B-haloboration products tmp−B(Hal)−NtBu−BH(Hal), while reactions with H2B(Hal)−SMe2 produce a mixture of two isomers by competing hydroboration and haloboration reactions. Tmp−BH−NtBu−AlH2 was obtained from 1 and AlH3−NMe3. It is a dimer in the solid state with pentacoordinate Al atoms and AlH2Al bridges. Hydrosilylation of 1 was achieved with Me2SiHCl, SiHCl3 or Ph2SiH2 to give the N-silyl-substituted diaminoboranes tmp-BH-NtBu−SiX3−nRn. Me3SnH and Bu3SnH behave similarly, giving the corresponding N-stannylated diaminoboranes. However, when Ph3SnH was treated with 1, the stannylborane tmp−B(SnPh3)−NHtBu was formed showing an umpolung of the hydrostannylation. Organyllithium compounds provide access to N-lithiodiaminoboranes of the type tmp−BR−NtBu−Li. The stability of these compounds depends on the substituent R. The least stable compound was the B−tBu derivative followed by the B-methyl compound. However, in the presence of TMEDA tmp−BMe−NtBu−Li is sufficiently stable to allow reactions, e.g. with B-chlorocatecholborane, to produce tmp−BMe−NtBu−BO2C6H4. The most stable lithium compound so far is tmp−BPh−NtBu−Li−OEt2, whose structure has been determined by X-ray crystallography. MgBu2 behaves like LiR and both of its Mg−C bonds can be used for the insertion reaction. The same is also true of ZnMe2. In contrast, at ambient temperature, only one of the E−C bonds of triorganylalanes, triorganylgallanes and InPh3 is used for the insertion reaction. In the solid state, most of the new compounds show a weak to strong coordinate bond between the electrophilic centre (Li, Mg, Zn, Cd, B, Al, Ga and In) and the nitrogen atom of the tmp group which generates a four-membered ring.

The United Kingdom government's draft bill to reform the libel laws in England and Wales does not go far enough and will do little to tackle the problem of unacceptably high costs, concludes a cross party committee of peers and MPs set up to scrutinise the bill before legislation.

The committee of both houses of parliament says the draft defamation bill fails to confront the high costs and uncertainty about outcomes that are said to be the key factors chilling free speech.

The bill makes some changes to the law and codifies some parts of the existing case law in statutory form, but the committee …

Teacher training programs have recently embraced the concept of reflection in the preparation of capable professionals for educational practice. This study included reflection as part of the design of a teaching-learning program developed to train pre-service kindergarten teachers to teach mathematics. The participants in this study were 40 pre-service teachers who enrolled in a two-year program of kindergarten teacher education in Taiwan. This study was designed to assess whether including reflection as a component of the teaching-learning program enabled teachers to better promote their mathematics learning and teaching competence. The results of this study show that engaging in reflection and preparing a learning portfolio can help pre-service teachers gain mathematical knowledge and learn more about their own teaching methods. The results also suggest that mathematical knowledge and pedagogical content knowledge can increase over time. Finally, this study discusses how to apply reflection in teacher-education programs in order to promote the successful professional development of pre-service teachers.


We describe a new method for measuring angular deviations of linear actuators as small as 0.1 /spl mu/rad//spl mu/m. Two designs of ultra-linear actuators for cavity ring-down spectroscopy are characterized and compared by achievable sensitivity.


Zhaheba Carboniferous volcanic rocks mainly composed of basahs and basaltic andesites occur within Upper Carhoniferous Batamayi Group,north of Zhaheba ophiolite in the eastern Junggar.These rocks have relatively high Mg~#(64~73)values,moderate TiO_2(<0.85%),Al_2O_3(13.75%~16.88%),but low CaO(4.51%~7.28%)and FeO~T(5.82%~7.71%)contents,showing characteristics of primitive magmas.These rocks have relatively high Na_2O/K_2O ratios(>1)and alkali contents(Na_2O+K_2O)= 4.3%~7.1%).They are enriched in LILEs but relatively depleted in HFSEs,with strong negative Nb-Ta anomalies,showing typical characteristics of subduction zone.These samples are slightly enriched in LREEs((La/Yb)_N=1.0~2.1)and possess weak Eu and Ce anomalies(0.94~1.08,1.00~1.06,respectively),without significant fractionations of HREEs(Gd_N/Yb_N=1.1~1.3). Furthermore,they have high radioactive Sr(I_(Sr)=0.705282~0.705420)and low radioactive Nd(e_(Nd)(t)=+6.59~+7.58). These characteristics,along with their low contents ofTh(<0.55×10~(-6))and Pb(<3.52×10~(-6))and high ratio of Ce/Pb(4~79),preclude the possibility for involvement of continental crust,suggesting that they were most likely produced in a subduction- related environment.Their high Ce/Th(18~32),Ce/Pb,Ba/Rb(21~76),Ba/Th(>179),e_(Nd)(t)values and lack of obviuus Ce anomalies indicate that there was no significant involvement of subducted sediment during their genesis.Moreover,their trace elements and Nd-Sr isotope compositions are consistent with their origination from a mantle wedge metasomatised by slab-derived fluid. Different from typical arc-related magmas,however,most Zhaheba samples show negative Pb anomalies and relatively high Ce/Pb ratios,which can probably be ascribed to Pb-poor fluid derived from an amphibolite-facies slab in high temperatures.These characteristics indicate that an intra-oceanic subduction environment existed in the eastern Junggar,and that the Junggar Ocean must close after the Late Carboniferous.


Epstein–Barr virus (EBV) is associated with numerous reactive and neoplastic lymphoproliferative disorders. In vitro, EBV infection can transform B‐lymphocytes and induce phenotypic alterations. This study presents the clinicopathological features of four cases with malignant lymphoma, which showed phenotypic and/or genotypic alterations during the course of the disease.


A new advanced medical emergency system has been proposed and designed to facilitate and computerize all the processes involved in an emergency. The proposed system contacts the ambulance emergency system, locates the correct and nearest available ambulance, accesses a Smart Online Electronic Health Record (SOEHR) that can critically assist in pre-hospital treatments, and identifies availability of the nearest available specialized hospital all through communication with the Hospital Emergency Department System (HEDS) which provides early and continuous information about the incoming patient to the hospital. Emerging and advanced technologies such as mobile web services, SOA, SOAP, HL7 and GPS have been extensively used to design, develop and integrate all system components.


One of the current projects of the Polish- Slovak Archaeological Mission in Tell el-Retaba is the exploration of a large area of the Third Intermediate Period settlement. During the 2017 season several houses belonging to this settlement were partly excavated. House {2147}, in which several phases of occupation could be distinguished, was particularly interesting. This house yielded an unusually rich set of small finds, including a bronze forked butt of a spear, and a set of lead fishing-net sinkers


SUMMARY Farewell Spit is a recent formation, probably post-glacial. It has been moulded by many forces, the most important being the longshore drift which moves northwards up the West Coast of the South Island. Several interacting zones are present on the Spit, indicating that it is undergoing a continuous process of change, relying mainly on the constancy of the longshore current, and the dominant wind direction. Cape Farewell consists of the Pakawau Group coal measures overlain by a marine transgressive sequence of sandstones, mudstones and limestones, forming the Abel Head Formation.

I must comment on Gary Jones' assumption that the chief nurses of Trusts distance themselves from the profession (Letters, January 13).


Obesity has become a critical concern in the present day being an important source of the chronological diseases. Consequently, factors that lead to obesity are receiving growing attention as a source to explore ways for controlling chronic results. Obesity mainly results from unhealthy eating habits and the role of television is found profound in promoting such behavior. The underlying study is aimed to fill the gap of such evidence in the context of the developing country, considering the case of Pakistan. Using sample size of 250 respondents for the questionnaire based enquiry, the study concluded that obesity has direct relationship with the overeating, hunger, impulsive and statusCo. However, the hypothesized relationship between the obesity and the quality education was not found significant. The originality of the study lies in adding to the limited literature about the behaviors and its respective impulsion factors that are growing obesity in Pakistan. The study has thus opened an avenue to expand the literature by conducting reassessment of factors for the results validation or rejection. Furthermore, on the policy front it provides guideline for the proliferation of the content by regulators. Also it provides an important parenting guideline in determining the level of interaction of television screens and younger children.


Cocamidopropylamine Oxide is a tertiary amine oxide used in a wide variety of cosmetic formulations. This ingredient functions as a hair conditioning agent, surfactant-cleansing agent, surfactant-foam booster, and surfactant-hydrotrope. It may be supplied as 35% active ingredient, and be used at concentrations between 5% and 15%. As supplied, it contains <0.3% free amidoamine and <5 ppm dimethylamidopropylamine. As a class, amine oxides are reported to be relatively nontoxic. The oral LD 50 values of amine oxides range from 2 to 6 g/kg. A 5% active Cocamidopropylamine Oxide solution was not a primary dermal irritant in rabbits. Amine oxides are reported to be nonirritating to the skin and eyes at 2% and mildly irritating at 10%. In a clinical study, Cocamidopropylamine Oxide was not a sensitizer, although some mild irritation was produced during the induction phase. These data were not considered adequate to complete a safety assessment of this ingredient. Additional data needed include: (1) Ultraviolet (UV) absorption data; if absorption occurs in the UVA or UVB range, photosensitization data are needed; (2) Dermal absorption data; if dermal absorption occurs, 28-day dermal toxicity and reproductive and developmental toxicity are needed; and (3) two genotoxicity studies, one using a mammalian system; if positive, a 2-year dermal carcinogenicity assay performed using National Toxicology Program (NTP) methods is needed. Until these data are provided, the available data are insufficient to support the safety of Cocamidopropylamine Oxide for use in cosmetic products.


Artificial intelligence based computing systems like artificial neural networks (ANN) have recently found increasing applications in predicting complex chemical phenomena like combustion properties. The present work deals with the development of an ANN model which can predict the derived cetane number (DCN) of oxygenated fuels containing alcohol and ether functionalities. Experimental DCN's of 499 fuels comprising of 116 pure compounds, 222 pure compound blends, and 159 real fuel blends were used as the dataset for model development. DCN measurements of sixty new fuels were carried out in the present work and the data for the rest was collected from the literature. Fuel chemical composition expressed in the form of eight functional groups namely paraffinic CH3 groups, paraffinic CH2 groups, paraffinic CH groups, olefinic -CH=CH2 groups, naphthenic CH-CH2 groups, aromatic C-CH groups, alcoholic OH groups and ether O groups, along with two structural parameters namely, molecular weight and branching index (BI), were used as the ten input features of the model. The qualitative and quantitative determination of functional groups present in real fuels was performed using H nuclear magnetic resonance (NMR) spectroscopy. A robust ANN methodology was followed to prevent over fitting using a multilevel grid search and genetic algorithm. The final developed model with two hidden layers was tested with 15 % of randomly generated unseen points from the dataset and a regression coefficient (R) of 0.992 was observed between the experimental and predicted DCN values. An average absolute error of 0.91 obtained from the test set indicates that the developed ANN model is successful in predicting the DCN of oxygenated fuels and captures the dependence of the fuel's ignition quality (i.e. DCN) on its constituent functional groups.


Landslides induced by engineering construction are very common in reality; it is necessary to clarify the causes of landslide failure to avoid similar accidents. A landslide induced by highway construction is taken as a case. Field observations, data collection, and analyses were used to investigate the deformation and causes of the landslide. The failed slope is mostly comprised of gravel soil, there were some shear cracks on both sides of the slope before sliding, and most tensile cracks were connected with shear cracks after sliding. The cut slope of this highway was designed to be protected by prestressed anchor sheet piles. However, in the construction process, the slope in front of the antipiles was removed when the piles were constructed without any anchor cables, which led to the shear damage of a row of anti-slide piles with a 15-meter-long cantilever. Moreover, continuous rainfall over several days aggravated the landslide damage because of increase of the self-weight and degradation of the mechanical parameters of the slope materials. The mechanical and simulation analyses both show that the resistance provided by the cantilever piles was not enough to prevent the force behind the piles. The irrational construction process and rainfall caused the slope failure.


Education is a conscious and deliberate effort to create an atmosphere of learning and the learning process so that learners are actively developing the potential for him to have the spiritual power of religion, self-control, personality, good values, and skills needed him, society, nation and state. the realization of discipline can not be separated from the role of parents and educators. Disciplinary punishment is not to make students understand that the prisoner for his mistakes through suffering or to scare through the threat of disciplinary punishment that does not imitate or do it in order to have influence educate every sentence. actions of teachers who are providing discipline for the good pupil criminalized worthy goal to be able to know the teacher who is giving the discipline for the good pupil worthy criminalized. This type of research is a kind of normative legal research and concluded the teacher who was carrying out his profession as an educator in school is disciplining students can not be convicted because of disciplinary action the students will be educated properly.


A vibration model is proposed and analyzed dynamically to study the selfsynchronization theory of dual-mass vibration system. The differential equations of systematic motion are derived by applying Lagrange's equations. As two uncertain parameters, the coefficients of instantaneous change of average angular velocity and the phase difference of two exciters are introduced to derive the coupling equations of angular velocity of the two exciters. The conditions of synchronous implementation and stability are derived by utilizing the modified small parameter average method treated as non-dimension to the parameters. The swing of the vibration model plays a major role in the self-synchronization of two motors. The mass ratio of two eccentric blocks has an effect on the stability of synchronous operation.


This work investigates the performance of older adults in tasks related to recognition of tactile symbols. We conducted experiments to evaluate different tactile symbols with varying elevation, shape form (outline, fill), and symbol preference in general. Experiments were performed with the general population of visually impaired (N = 6, age mean = 46.3) and with visually impaired older adults (N = 9, age mean = 76.8). We used both qualitative and quantitative methods to evaluate the experiments. The results indicate that even older adults are capable of distinguishing between six different tactile symbols. Participates frequently failed to connect meanings of abstract symbols with functions of a hypothetical orientation system terminal.


less than wholly convincing. But it is pursuasive enough to take seriously his conclusions about the relationships between the exercise of power in American cities and the production of fiscal strain and no less important the contradictory nature of this power in provoking urban crises which negate the benefits the power was exercised to obtain. Community Work and the State is the eighth in the Community Work series and like the others is a mixed bag of essays (fifteen in this instance) both in content and quality. What it isn't, is a collection of essays about community work and the state. Apart from in the title and the first two essays, the theme only surfaces occasionally. There can be few occupations more introspective about their aims and their craft than community work, and out of this has come some sensitive thinking and writing which comes through in a number of these essays despite the superfluity of 'crisis' talk and political hyperbole. There remains the nagging doubt, notwithstanding its self examination, that community work really hasn't defined its constituency and that its priorities are constantly being assailed by new minorities demanding recognition within the pantheon of the oppressed. Blacks, women, the poor, the handicapped, teenagers, the elderly, gays, council tenants, the homeless, Asian girls, all appear in these essays as the constituents of community work. Can community work continue to respond to all these demands? Can it afford to? Should it? JOHN EDWARDS Bedford College, University of London


This work is a result of an investigation realized together with the construction of a proposal for a curricular reorganization of the licenciatura courses, in a communitarian university of Santa Catarina State. It approaches questions related to the most significant stages of the defined process and to the constructed proposal, established in the idea of a constitution of an integrated curricular organization. The study starts showing that the construction process was based on the courses' adequacy to the national curricular lines, both general and specifics. It was also based on the necessity of an answer to the new social and employment orders, on the economic and financial allowance to the realization of courses and the formation of a basic education's professional with a solid theoretical formation and capacity of dealing with the pedagogical practices. It follows presenting characteristic aspects of the courses of licenciatura's reality in the University, as well as the process that resulted in the reorganization of the politic-pedagogical projects, from a common base. This common base is constituted by the knowledge that composes an essential nucleus of formation of the education's professional, and the curricular organization for nucleus and groups, in order to promote the unity between the courses. It concludes recognizing that the process of inquiry and construction of the curricular reorganization's proposal was marked by some challenges, having been preserved the intention to assure aspects considered necessary to the professional's formation, favoring the constitution of an educator's identity to the egresses of these courses of graduation.

: Pr doped Mg 2 SnO 4 in the scope of 0~1.5nm% was synthesized by hydrothermal method and corresponding calcination at low temperature. X-ray diffraction (XRD), Scanning electron microscope (SEM) and luminescence/ fluorescence spectrophotometer were applied to characterize Pr doped Mg 2 SnO 4 . The relationship between Pr doping contents and the morphologies of Mg 2 SnO 4 particles was studied. The results show that the Mg 2 SnO 4 : Pr 3+ are con-firmed to be the cubic inverse spinel structure and exhibit as cubic particles. An augment of the grain sizes and obvious sharpen edges of the cubic nanoparticles are observed with increasing Pr doping amounts. The emission spectra of Mg 2 SnO 4 nanoparticles with various Pr doping contents indicate two bands centered at 530 nm and 570 nm, respectively. The former emission band is related with the oxygen vacancies in Mg 2 SnO 4 and the latter emission band is attributed to the 3 P 0 - 3 H 5 energy transitions of Pr 3+ . The increase of luminescence center's number and Pr-doped Mg 2 SnO 4 particles size result in an obvious enhancement of emission intensity centered at 570 nm with increasing Pr doping contents.


The article concerns the modelling and control of a digital hydraulic cylinder drive involving a standard differential cylinder controlled by four digital flow control units in a full bridge circuit. A special focus of the modelling lies in the compromise between the prediction accuracy of the model and the computational efficiency of the control algorithms based on the models. A physically motivated model for the static pressure-flow-characteristic of digital flow control units is derived and compared to conventional models. Based on this model, a switching algorithm is developed which finds an optimal switching combination for each DFCU, if certain dimensioning conditions are fulfilled. The algorithm forms the inner loop of a hierarchical controller for the overall system. In an outer loop, a flatness-based tracking controller is used for the independent metering control of the cylinder. The models and algorithms developed in this article are validated in experimental investigations using a laboratory test rig.

Suppose there are d diploids and m tetraploids. In the language of [2], there are m models h = 1, h = 2, . . .h = m, where h is the number of hybridizations. Each model has a different number of parameters. The main difficulty with the network prior is that the normalization constants are needed for the different models. Let W be the network topology and node times. The conditional priors π(W |h) must be comparable for different values of h. To do this analytically, it is necessary to integrate out the parameters in W , ie calculate for each h the value of

Plant macrophytes in wastewater treatment systems are important for providing various ecological and environmental benefits, e.g. detoxification and removal of toxic heavy metals. In this study, phytoremediation of four heavy metals (Cd, Cu, Pb and Zn) by water hyacinth (E. crassipes) in sewage wastewater stabilization ponds under humid lowland tropical climatic conditions in Papua New Guinea was studied using a purposive design and grab sampling technique. The wastewater and plant samples collected were analysed for the heavy metals. In almost all cases, an increasing concentration of heavy metals exceeding the standard (FAO and WHO) minimum permissible levels was measured in both the wastewater and the leaves. The general trend in concentration of the effluent pond was such that Pb>Zn>Cu>Cd in the wastewater and Zn>Cu>Pb>Cd in the leaves, respectively. The high variability in heavy metal concentration ranged from between 57-99% in the wastewaters and 61-63% in the leaves, respectively. The availability in the effluent wastewater probably results from decomposition of plant matters and release of the heavy metals bioaccumulated back into the wastewater. A management option to address high availability and mobility in the wastewater is to remove the plant macrophytes well before senescence and turnover of plant matters.


In an anechoic environment, distance perception for nearby sources degrades if there is no low-frequency spectral content in a stimulus, presumably because of the importance of low-frequency interaural level difference cues (Brungart, J. Acoust. Soc. Am. 106:3589-3602). However, distance perception is essentially the same for monaural and binaural stimuli simulated at nearby distances in reverberant space (Shinn-Cunningham, Santarelli, and Kopco, 1999 ARO Abstract #103). These results suggest that low-frequency stimulus content may be less critical for distance perception of nearby sources in reverberant space than in anechoic space. The current study examines the effect of spectral content on distance perception in reverberant space.


This article investigates the problem of specific emitter identification (SEI), i.e., radar emitter fingerprint or individual emitter identification, which first measures the emitter-specific differences caused by radar's nonlinearities, e.g., mixer, power amplifiers, transmitter, and then makes a decision. In this article, the SEI problem is considered in the single-modal, dual-modal, and multimodal scenarios, respectively. First, a multimodal subspace interactive mutual unit is proposed to perform information interaction between radar signal and its multiple transformations. Based on this, a data-driven multimodal subspace interactive mutual network is then built to solve the SEI problem. Extensive experiment results demonstrate that the proposed algorithm achieves superior identification performance on the airplane measured data.


ABSTRACT This work presents a new geomorphological map (1:50,000) of the São Pedro region in southeastern Brazil. It incorporates new information about landform development and updates the classical legend of the Recherche Coopérative Sur Programme 77 that supported the previous map drawn in 1978. According to the new map and associated papers, tectonic structures have controlled the orientation of the streams that have dissected the regional landforms, especially during wetter periods. Under dry conditions, the planing process caused faster escarpment retreat of the São Pedro ridge and gave rise to a glacis and its Pleistocene colluvial sandy cover. The escarpment, glacis, and other regions were dissected during subsequent wet periods, forming the upper Quaternary main fluvial terraced levels of the Piracicaba and Tietê rivers. Finally, this geomorphological arrangement was disturbed by the reactivation of old structures in the current tectonic environment.


This article describes attachment perspectives on unresolved loss and dissociation beginning with Bowlby's conceptualisation of grief and bereavement, and subsequent discussion of unresolved/traumatic loss on the Adult Attachment Interview (AAI). An AAI selected by the author will be utilised to show how traumatic factors in the speaker's childhood, including sexual abuse and maternal neglect and rejection, may result in an unresolved, complicated grief process. The author intends to illuminate the implications of early trauma and subsequent loss on one's sense of self and relational life, and to suggest an integrative treatment model that would address early traumatic experience and subsequent bereavement.


This paper presents the views of an advocate of honest marketing of nutrition and the elimination of irresponsible practices, especially the role (or lack of a role) of supplements in sound nutrition practices.


Abstract:The celebration in 2011 of the congress "El exilio republicano de 1939 y la segunda generación" contributed greatly to focus the attention on a group of writers who, despite the existence of some studies, had gone partly unnoticed. However, at the same time, it showed the silence under which there were still the works of many "niños de la guerra" who had resorted to artistic creation. Beyond the Hispanic-Mexican generation, a group on which much of the criticism has revolved, there are many other writers, such as Michel del Castillo, Manuel Fernández-Montesinos, Jaime Salinas or Tatiana Pérez, who are also part of that generation. Therefore, this work aims to bring to light the existence of other children who marched to countries such as the USSR, Belgium or USA, fleeing Franco's troops and who became writers, either to tell their testimony, or to develop a literary trajectory.


Modelling of multi-layered groundwater basins; a case study ofMGWBNo. 338 Paczkow–Niemodlin. A b s t r a c t. The objective of this paper is to present the advantages and problems related to the application of a multi-layer model in hydrogeological investigations, exemplified by the Main Groundwater Basin No. 338. The main aquifer in this basin is Neogene, but Quaternary, Cretaceous and Palaeozoic-Proterozic aquifers have also been identified there. Due to the presence of numerous permeable layers, separated by impermeable ones of irregular distribution in the Neogene aquifer, 27 model layers have been distinguished, including 10 water-bearing horizons. A large number of model blocks caused the increase of the computational time, and a large number of layers have lengthened the calibration time of the model. However, anthropogenic or geologic threats to multi-layer structures have justified such a large number of layers, enabling the water balance for the selected part of the basin or for the selected depth intervals with groundwater of good or bad status.


In pressure irrigation-water distribution networks, pressure regulating devices for controlling the discharged flow rate by irrigation units are needed due to the variability of flow rate. In addition, applied water volume is used controlled operating the valve during a calculated time interval, and assuming constant flow rate. In general,
a pressure regulating valve PRV is the commonly used pressure regulating device in a hydrant, which, also,
executes the open and close function. A hydrant feeds several irrigation units, requiring a wide range in flow
rate. In addition, some flow meters are also available, one as a component of the hydrant and the rest are placed
downstream. Every land owner has one flow meter for each group of field plots downstream the hydrant. Its lecture
could be used for refining the water balance but its accuracy must be taken into account.
Ideal PRV performance would maintain a constant downstream pressure. However, the true performance depends on both upstream pressure and the discharged flow rate. The objective of this work is to asses the influence of the
performance on the applied volume during the whole irrigation events in a year.
The results of the study have been obtained introducing the flow rate into a PRV model. Variations on flow rate are simulated by taking into account the consequences of variations on climate conditions and also decisions in
irrigation operation, such us duration and frequency application. The model comprises continuity, dynamic and
energy equations of the components of the PRV.


Small businesses are a vital part of our economy, accounting, depending on one's definition, for perhaps forty percent of the business activities in this country. Capital formation for small businesses historically has been fraught with difficulties, which include nonsensical and discriminatory state securities laws. Because of the statutory exclusions from NSMIA's preemption provisions, NSMIA itself provides no relief from state securities laws for small businesses engaged in capital formation. NSMIA does, however, contain a broad delegation of authority to the Commission, which the author believes could be used to expand significantly and beneficially the preemptive scope of NSMIA and thereby provide important benefits from the capital formation activities of small businesses.


In this piece, the author discusses recent feminist theory, in particular feminist theory of cyborg identity, and examines some media representations of a woman-of-color superintendent. It is suggested that the cyborg image offers alternative ways to consider the issue of diversity and educational leadership, including the superintendency.


We investigate the nuclear dynamics near a real-valued conical intersection that is perturbed by a complex-valued spin-orbit coupling. For a model Hamiltonian with two outgoing channels, we find that even a small spin-orbit coupling can dramatically affect the pathway selection on account of Berry force, leading to extremely large spin selectivity (sometime as large as 100%). Thus, this Letter opens the door for organic chemists to start designing spintronic devices that use nuclear motion and conical intersections (combined with standard spin-orbit coupling) in order to achieve spin selection. Vice versa, for physical chemists, this Letter also emphasizes that future semiclassical simulations of intersystem crossing (which have heretofore ignored Berry force) should be corrected to account for the spin polarization that inevitably arises when dynamics pass near conical intersections.
