Objective To study the impact of farmland climate factors on the rodent community. Methods From 1978 to 1993, canonical correlation analysis of the farmland rodent density and climate factors in Kaijiang county, Sichuan province was conducted. Results In the period, the overall farmland rodent density was 5.58%-26.57%; Apodemus agrarius density 1.91%-18.41%, Rattus norvegicus density 0.68%-10.86%, and Anourosorex squamipes density 0.47%-9.50%. Among the canonical correlation coefficients between 12 climate factors including temperature, humidity, rainfall and sunshine, and four variables (overall rodent density, Ap. agrarius density, R. norvegicu density, An. squamipes density), the first couple (correlation coefficient r=1.0000) was statistically significant (χ2=248.7032,P0.01). The largest coefficient of the rodent density was noted in the overall rodent density (4.7748), and the largest coefficient of the climate factors was the average sunshine from July to August (-3.1532), followed by average humidity from July to August (-1.6177) and then average rainfall from July to August (-1.4652). All were negatively correlated. Conclusion Farmland rodent quantity was mainly affected by average sunshine, humidity and rainfall from July to August.


The empirical problem was that patients had nausea, vomiting, epigastric pain etc frequently during and after administration of the medication. The hypothesis was "drugs were not administered properly, and that diluting them according to their pH and managing them more time will decrease the adverse effects". The work was carried out in surgery of the Hospital II-2 of the MINSA Tarapoto in the first year worked with 549 patients who were hospitalized in June 2013 - 2014 and in second year June 2015 to June 2016 in 476 patients. The research is quasi – experimental. The data were obtained by clinical observation, interviews, and records of nursing. In the control group were diluted drugs traditionally, all with saline (NaCl 0.9% and in 5-10 minutes). In the group control the average result was, 98.6% of patients had some type of adverse effect: nausea 26.8%, 12.5%, vomiting epigastric pain 18.2%, 8.1%, metallic taste vertigo 17% and 11.5% venipuncture pain. The experimental group diluted medications according to the pH with glycoside solution or saline and in a time of 15 - 20 minutes, taking the average result at 3 months of evaluation managed to observe a significant reduction of the adverse effects, and improved even more in the following evaluations. There is therefore a significant difference (with a p value in the Chi-square of 0.0163 95% confidence test) between the two groups.


Effects of stamping and roasting treatments on change of volatile aromatic components in curry powder were investigated by gas chromatography. These were conducted for improving volatile aromatic flavor and for improving aging effect. Major volatile aromatic components of curry powder were eugenol, cuminaldehyde, myristicin, anethole, eugenolacetate, cinnamaldehyde, linalool, limonene, p-cymene and . By stamping treatment, the content of low volatile components increased till 10 min, whereas that of high volatile components started to increase after 10 min. The content of low volatile components decreased with increasing roasting time.


The role of unbiased migration in cooperation was explored based on the stady of spatial evolutionary game in the framework of a variety of spatial structures,including regular lattice,continuous plane and complex network.A striking finding is that migration plays a universal role in cooperation,regardless of the kind of spatial structures.For high degree of migration,cooperators cannot survive due to the failure of forming cooperator clusters to resist attacks from defectors.While for low degree of migration,cooperation is considerably enhanced compared with that in statically spatial game,which is due to the strengthening of boundary of cooperator clusters by the occasionally accumulation of cooperators along the boundary.The cooperator cluster thus becomes more robust than that in static game and defectors nearby the boundary may be assimilated by cooperators,so the cooperator cluster expands,which facilitates cooperation.The general role of migration can be substantiated by sufficient simulations associated with heuristic explanations.An aspiration-induced migration was proposed which individuals will migrate to new sites provided that their payoffs are below some aspiration level.It is found that moderate aspiration level can best favor cooperative behavior.In particular,moderate aspiration level enables cooperator clusters to maintain and expand whereas induces defector clusters to disintegrate,thus promotes the diffusion of cooperation among population.The results provide insights into understanding the role played by migration in the emergence of cooperative behavior.

As part of a study into the effects of human activities on the welfare of free-living wildlife, the relative scale and severity of welfare problems in wild mammals and birds in Europe were investigated. Major cases were described and compared in terms of the nature and level of harm (pain, stress and fear) they cause, the duration of these effects and the number of individuals affected. The use of anticoagulant rodenticides, myxomatosis in rabbits, the poisoning of wildfowl by ingested lead shot, the contamination of seabirds with fuel oil, the effects of shooting, injuries due to collisions with road traffic and prédation by domestic cats all severely compromise the welfare of large numbers of animals. Practical approaches to the alleviation and prevention of some of these welfare problems are discussed. We suggest that in assessing the environmental impact of new developments and technologies prior to their implementation, possible consequences to wildlife welfare should always be considered.


Effects of pollination times on cross seed production of tomato in protected field were studied by employing the parents of tomato hybrid combinations-"Jinpeng1" as materials to carry out three pollination times treatments by one time,two times and three times on female parent plants that their density is 222.7 plants/hm2 and pruning way is two branches pruning,during the pollination period.The results showed that: the highest fruit bearing percentage is obtained by three times pollination.there is most significant difference than by one time pollination,not significant difference than by two times pollination;there are more significant differentce on the seed number per fruit,the seed yield per fruit,plot field,the tendency of seed germination and the rate of seed germination than by one time pollination,not significant difference than by two times pollination;the highest thousand seed weight is obtained by two times pollination,there is no significant different between one time pollination and three times pollination.Two times pollination is the best repeated pollination.


Background. The superior mesenteric artery (SMA) is exposed and dissected during pancreatic resections (PR) and mesenteric vascular surgery (MVS). The resulting damage of the surrounding extrinsic and intrinsic vegetative nerve plexus can lead to a temporary or treatment refractory diarrhea. Objective. This study aimed to provide an overview of the current status of SMA revascularization and dissection-associated diarrhea (SMARD syndrome) in Germany. Material and methods. After a selective literature search (SLS) on the frequency of newly developed postoperative diarrhea after PR and MVS, an online survey was initiated. Results. The SLS (n= 4) confirmed that newly developed postoperative diarrhea is a frequent complication after preparation for revascularization (RV) or dissection (DIS) of the SMA (incidence approximately 62%). Treatment refractive courses were relatively uncommon with 14%. Out of 159 centers 54 took part in the survey and 63% stated that they carried out an SMA RV/DIS during PR or MVS. The average PR per center was 47 in 2018 and 49 in 2019. The average MVS was 5 per center in both years and on average 3 patients suffered from SMARD syndrome. Conclusion. This survey recorded the current status of the SMARD syndrome in Germany for the first time. So far there are no recommendations for the treatment of such a diarrhea. The results show that initially a symptomatic treatment should be carried out. Due to the complexity of the pathophysiology, causal treatment approaches have not yet been developed.


Abstract Musa × paradisiaca belongs to the family Musaceae. It is one of most popular fruit crops in Thailand and is traditionally used for various ailments. The present study was carried out on the anti-gastric ulcer activity of M. × paradisiaca pseudostem in experimental animals. Experimentally induced gastric ulceration was created using absolute alcohol, indomethacin and swimming stress. Pre-treatment with the ethanolic extract of pseudostem at doses of 250, 500 and 1,000 mg/kg for 1 h prior to induction of gastric ulcer showed a significant (p<0.05) dose-dependent reduction to the ulcer index from the low dose (250 mg/kg) in all experimental models when compared to the control group. The protection percentage of ethanolic extract of pseudostem at a dose of 1,000 mg/kg for absolute alcohol, indomethacin and swimming stress models was 75.06, 66.49 and 67.11 %, respectively. For anti-secretion effects, the ethanolic extract of pseudostem caused a significantly (p<0.05) decrease in gastric acidity with no effect on gastric volume, total protein and pepsin. Furthermore, pre-treatment with ethanolic extract of pseudostem in different doses promoted gastroprotective effects by significantly (p<0.01) increasing gastric wall mucus content from the lowest dose (250 mg/kg) and increasing gastric pH at the highest dose (1,000 mg/kg) when compared to the control group. The findings therefore indicate that pseudostem of M. × paradisiaca possess anti-ulcer activities in experimental animals induced by absolute alcohol, indomethacin and swimming stress, which might be due to promoting mucus secretion.  Keywords: gastric ulcer; anti-gastric ulcer activity; Musa × paradisiaca pseudostem


Baker's yeast reduction of nitro- and imide-containing ketones gives the corresponding secondary alcohols in good yields with excellent optical purity. Among the imide groups examined, the ketones with saccharin moiety give the products in the best chemical and optical yields.


While the management of alpine natural hazards in settlements follows highly developed operational standardised procedures in many countries, there are very few approaches for a systematic survey and assessment of these natural hazard processes and the related risks and for a sustainable planning of measures for roads. This is even more surprising against the background of the ongoing increase of traffic in Europe and its economic importance.


On 5 May 2003, USS SHOUP conducted sonar training for 4 h while transiting through the Strait of Juan de Fuca and the Haro Strait. During the time period when the sonar was configured for long‐range operations, the transmissions were alleged by some observers to have influenced the behavior of the resident J‐pod of orcas. Additionally, the transmissions were received and recorded on various hydrophones deployed for monitoring marine mammal vocalizations. The U.S.‐Navy‐commissioned detailed reconstruction of the event that relates the location of SHOUP, the J‐pod, and the monitoring hydrophones during the time period of SHOUP's long‐range sonar operations is presented. By combining high‐fidelity predictions of the acoustic field with the in situ acoustic recordings, the reconstruction provides a detailed, moment‐to‐moment picture of the worst case estimates of the sonar sound levels experienced by the J‐pod.

The inability of Nigeria to make its inflation rate a single digit motivates this study. This paper
aims to empirically investigate whether inflation is solely caused by the increase in money
supply beyond what is required by the economy, as maintained by monetarists using Nigerian
data. Autoregressive Distributed Lag Model (ARDL) was used as the tool of econometric
analysis on Nigerian time series data for 48 years. The ARDL was chosen because unit root
tests were conducted. The results show that variables are not integrated in the same order.
Money supply increment is demonstrated to be inflationary only in the short-run. The existence
of other factors that influence inflation in the country is also evident. While money supply has
no significant influence on inflation, the GDP and the constant have a significant influence on
inflation in the long-run. Therefore, justification is provided for the myth of monetarist theory
of inflation, claiming that money supply increment is a sole source of inflation, especially in
Nigeria. Even though the result of the Wald test shows that the coefficients of money supply
combined have a significant effect on inflation in conformity with the monetarist theoretical
arguments, such effects are limited to short-run only. The findings of the research are limited
to Nigeria whose data are used, based on ARDL as the econometrics techniques applied, for a
period of 48 years from 1970–2017. Generally speaking, explanations for theories regarding
inflation, especially in developing nations, should not be taken for granted. The research
empirically demonstrates that the monetarist theory of inflation is a myth and not reality by
using Nigerian data. It also suggests that other theories should be empirically tested to check
which one best explain the nature of inflation dynamics in a country to proffer a better solution
to a high inflation rate problem.

The recent outbreak of severe acute respiratory syndrome (SARS) belongs to a broad family of viruses known as Coronaviridae. SARS-CoV-2 is an emerging global pandemic with a relatively low mortality rate. The virus has been mutated in a unique manner thus prolonging its search for its vaccine and drug therapy. SARS-CoV-2 is an enveloped virus consisting of many spike (S) proteins, which mediates its fusion to the membrane of the host cell. Its 'crown-like' appearance under an electron microscope has led to its name. The clinical symptoms that patients experience would be due to their central immune response to the infection. Pro-inflammatory cytokines play an essential role in cell growth and regulation of the immune system. However, its abundance could contribute to pathological conditions which can cause further injury and possible death. This brief review discusses the pathogenesis of the SARS-CoV-2 along with receptors that can be potentially targeted by therapeutic strategies, inhibiting the membrane fusion, genome replication and immune response.

Residual antibiotics can enter soil and water bodies through organic fertilizers with food safety risk via plants absorption, while how do plant growth and quinolone accumulation respond to residual antibiotics levels in soil or water is not clear. Hydroponic experiment in greenhouse was conducted with floating seedlings of tobacco as model plant to investigate the responses of quinolone antibiotics accumulation and plant growth to different levels of ciprofloxacin (CIP) and norfloxacin (NOR). Results showed that CIP and NOR inhibited the growth of tobacco seedlings. The plant height, stem circumference, maximum leaf width, and maximum leaf area of tobacco seedlings were significantly decreased. So as to the plant biomass of leaves, stems, and roots. Accumulation of CIP in the tobacco seedlings in the T3 was 1.1 times that of the tobacco seedlings in the T1, NOR in the T4 was 1.2 times that of the tobacco seedlings in the T1. And the higher the concentration, the more significant the inhibitory effect. Both antibiotics can be absorbed and accumulated by tobacco seedlings. Additionally, the inhibitory effect of CIP was greater than that of NOR.


Bulk traps in the high-resistivity buffer stack underneath the 2-dimensional electron gas (2DEG), which can interact with the high vertical electric field at OFF state, impose a critical challenge to the dynamic ON-resistance ( ${R}_{ \mathrm{\scriptscriptstyle ON}})$  of AlGaN/GaN-on-Si power devices. In this paper, the impact of substrate bias polarity on carrier injection/transport and buffer-induced current collapse has been investigated by using ramped and transient back-gating characterizations as well as TCAD simulations. High voltage applied to the conductive Si substrate can modulate 2DEG conductivity through the back-gate effect, whereby the dynamics of both acceptor and donor buffer traps are identified. Distinct buffer trapping and asymmetric vertical leakage under opposite top-to-substrate bias polarities have been observed, which are attributed to the fundamentally different carrier injection/transport mechanisms. It is suggested that the energy barrier at the nucleation-layer/Si interface can limit the electron injection from Si substrate into the buffer stack and consequently influence the buffer-related current collapse.

Introduction. The solution of modern problems of stabilizing the national economy, ensuring the social development of society is possible only on the basis of positive shifts, primarily in the aspect of strengthening the financial condition of business entities. One of the important components of the analysis and management functions is to ensure the stable development of the enterprise and its financial stability. The concept of financial stability is complex and multifactorial, which is determined by the economic environment in which the enterprise operates, as well as the results of its functioning, the ability to actively and effectively respond to changes in internal and external factors.
The purpose of the paper is in the study of the economic essence of financial stability, its determining factors, as well as the development of recommendations for improving the methodology of its management.
Results. The financial stability of an enterprise is a complex, multifactorial category. The philosophy of the definition of the economic category "financial stability" provides for consideration as a reproduction process. This category characterizes the economic relations that make up the financial mechanism for ensuring the progressive socio-economic development of the enterprise.
The analysis of theoretical research allows us to identify five approaches of scientists to determine the essence of financial stability. These approaches differ in the completeness of the characteristics of the financial condition of the enterprise.
The variety of approaches indicates the ambiguity of the authors' definition of the concept of financial stability. Each author interprets this economic category from the standpoint of the goals and objectives of its research. The complexity of the category of financial stability of business entities lies in its essence, displaying the level of the financial condition and financial results of the enterprise, the ability to fulfill its obligations and ensure the development of the enterprise while maintaining credit and solvency, relative independence from changes in internal and external factors. A quantitative characteristic of financial stability is a margin of safety, which is determined by the structure of property and capital and ensures financial independence and solvency in the current period and in the future. It is this definition that determines such a logic for assessing financial stability as a sequence with varying degrees of detail in the consideration of all processes associated with the movement of financial resources, which are expressed in a change in the structure of property and capital.
Conclusion. In general, the analysis of theoretical approaches to assessing financial stability and their generalization allows us to conclude that the financial stability of economic entities should be considered as a complex category, reflecting the level and structure of financial condition and financial results, the ability to fulfill their obligations and ensure the development of activities, while maintaining credit and solvency. It is also universal that the quantitative characteristics of financial stability should be considered a margin of safety, which the company, due to the structure of property and capital, and also ensures independence and solvency in the current period and in the future.


This study aims to provide a description of the positive predictions of international institutions, demographic bonuses and covid-19: will Indonesia really enjoy the demographic bonus in the midst of the Covid-19 pandemic? This study uses a qualitative method that uses a type of literature study which is carried out by examining several theories that depart from a problem then analyzed from various literatures ranging from available journals, the internet, and various existing facts. The data collection method used is through data reduction techniques, namely the selection, simplification, and transportation of data so that results or conclusions are drawn up systematically. This study concludes that the experiences of South Korea, China, and the United States are very different from Indonesia, these countries can enjoy a demographic bonus without any barrier variables in the form of the Covid-19 pandemic. Meanwhile, the demographic bonus with the growth of baby boomers in the Golden Indonesia era was obtained by this extraordinary event. Both indicators and parameters will of course differ from these countries. So this is a very big gamble for Indonesia to be in accordance with what has been predicted by the international institutions or vice versa.

Hydraulic transient events cause abrupt disturbance in the equilibrium state of pressurized water distribution system. They are initiated when a sudden operational breakdown happens like pump shut-off, rapid valve closing and opening etc. And they cause evolution and propagation of intense pressure waves. As a result, these events can lead to water column separation by producing significant negative pressure waves, which may cause catastrophic pipe failure and other problems. Therefore transient protection devices should be installed in the system to prevent any accidental or unintentional transient. Surge analysis helps us to identify possibility of transient and to design protection equipments. In context of Dhaka, frequent pump shut-off can be quite serious threat to the stability of newly installed network, if adequate protection measures are not taken. This paper provides a basic understanding of transient event, causes and consequences, major parameters, and suitable protection measures in context of Dhaka.

The psychology of ''ages'' presents a complete picture of the evolution of the ontogenetical human being, an account on the bio-psycho-social development of each human in every cycle of life. This opportunity has become the initial impact in choosing the theme, the evaluation of personality rate at puberty and teen age. In essence, our investigation has proposed to present a comparative study of several interrlated personalities, '''two psychology ages'': the late puberty and the medium teen age. We have put forth to synchnically evaluate the following features of personality: identity, emotional maturation, anxiety and the way of valuing the actual Romanian society.For the realization of this study we have applyed to a number of 72 people between 14-18 years, students of the 8th ad 12th grade from Moise Nicoara High School Arad.


This is a primer on psychoacoustics for the nonspecialist. In considerably less than 200 pages of text a relatively clear and painless introduction is provided to the behavioral science that is the basis for clinical audiology. The audiologist, ear, nose, and throat resident, or practicing otolaryngologist looking for a brief resume of terminology, experimental method, and theory in psychoacoustics will find it here. Perhaps two to three hours of reading will not transform you into a full-blown psychoacoustician, but it should help to dispel some of your anxiety on overhearing a discussion of isophonic contours or intermodulation distortion, or on coming face-to-face with a wave analyzer (see page 51). The final chapter on classical psychoacoustics fills half the book and is most important, especially for the reader not interested in entering the laboratory. Here the traditional testing methods and procedures for analysis of data are described in detail. Following


A new concept of space radiator of variable emittance for satellite thermal control is presented. The radiator is composed of two stages which exchange heat through radiation between finned surfaces covered with variable emittance coatings, whose emissivity is increased with temperature. Under cold conditions the radiative heat coupling between the stages is minimal, preventing the equipment subcooling, while in hot conditions the heat exchange is increased. A steady-state mathematical model was developed and numerically coupled to an optimization algorithm, and a design optimization procedure was performed. Two optimization criteria were employed: minimization of the radiator mass and the power consumption of heater under cold conditions. The Generalized Extremal Optimization algorithm was used as the optimization tool. The design was then modeled in detail using the SINDA/Fluint package considering orbital conditions of the EQUARS satellite. The performance of the radiator concept proposed here was also compared to a conventional design, for the same operational conditions. It is envisioned that the utilization of such radiators in micro-satellites will lead to considerable electric power savings for safe heaters and may contribute to a longer satellite life. In the design trade-off, the cost for this saving is additional radiator mass and volume.


ABSTRACT Learning to teach is a complex process that hinges on teacher candidates' personal experiences, values, beliefs and characteristics, as well as the contexts they are exposed to. Student teaching as a transitional period may create dilemmas for teacher candidates, who are new to the profession and still learning about what it means to be a teacher. Thus, this study examined the dilemmas experienced by a group of Taiwanese teacher candidates during the student teaching phase. Using the framework of dilemmatic spaces, we identified the sources of their dilemmas and the decisions they made towards the dilemmatic situations and further examined how they justified their decisions. Our findings suggest that conflicting ideologies and teacher candidates' identities as student teachers are the main sources of their dilemmas. In response to the dilemmas, teacher candidates showed different decision-making trajectories that revealed the different actions and justifications they took within the dilemmatic space.


The Colombian constitutional court has become one of the most recognized and powerful constitutional courts worldwide. Although it has only been working for 25 years, it has gained a very special place in the most relevant literature on the work of prominent constitutional courts in the global south such as the South African and the Indian Supreme Court, among others. Nowadays its case law and rulings are becoming very well known, especially those referring to social and economic rights enforcement, liberal rights, dignity, autonomy, women's' rights, euthanasia and dignified death, LGBTI rights, multicultural accommodations and indigenous rights, the so called basic structure doctrine, among many others. Its work has been very popular and influential in the Spanish literature during the last decades and is now taking its own place within the relevant English literature due to the translation of its most famous case law.


The 2010–2011 Canterbury, New Zealand earthquake sequence caused extensive damage to unreinforced masonry churches. A sample of 80 affected buildings was analysed and their performance statistically interpreted. Structural behaviour is described in terms of mechanisms affecting the so-called macro-elements, and damage probability matrices are computed. Regression models correlating mean damage level against macroseismic intensity are also developed for all observed mechanisms, improving the initial simple-linear formulations through use of multiple-linear regressions accounting for vulnerability modifiers, whose influence is evaluated via statistical procedures. Results presented herein will support the future development of predictive tools for decision-makers, also contributing to seismic vulnerability mitigation at a territorial scale.


PurposeThis paper investigates the relationships between responsible leadership and employees' knowledge sharing behavior and performance in the healthcare sector. The present study provides deeper insights into those relationships by uncovering the mechanisms through which relational and ethical dimensions of responsible leadership influence knowledge sharing outcomes. Drawing on the social exchange theory, this study examines the mediating role of trust in the leader and leadership support.Design/methodology/approachData were collected from 445 healthcare professionals in Pakistan. Structural equation modeling was employed to analyze the data.FindingsThe study findings revealed that responsible leaders enhance knowledge worker performance and knowledge sharing behavior through enhancing trusting relationships with followers and providing support. Furthermore, the authors investigated the moderating role of goal orientation, and the results showed that the effect of responsible leadership on knowledge worker performance was stronger for highly goal-oriented employees.Practical implicationsThis research suggests that human resource managers interested in fostering knowledge sharing behaviors, must focus on cultivating responsible leadership behavior within their organizations. Furthermore, this study findings propose that HRM practices should foster employee goal orientation in order to enhance knowledge workers' performance.Originality/valueThis study makes a novel contribution to the literature by shifting the research focus from the traditional view of leadership to a leadership style more responsive to the reciprocity nature of the relationships between employees and leaders. By shifting the focus to a relational-ethical based leadership style, the current study was able to fully uncover the underlying mechanisms linking responsible leadership to knowledge sharing outcomes.

High estimate of genotypic coefficient of variation (GCV) was observed for root splitting percentage, total chlorophyll, root carotene, leaf carotene and root forking percentage. High heritability with high genetic advance as per cent of mean recorded for the characters viz., leaf carotene, root carotene, total chlorophyll and root weight. Character association studies revealed the strong positive association of root yield with root carotene, root length, root weight, root diameter, inner core diameter, root forking percentage, root splitting percentage and leaf carotene. Path analysis indicated high positive direct effect of plant height, root length, root weight, root forking percentage, root splitting percentage and total chlorophyll on root yield.


Ischemic stroke following a snakebite is a rare complication. We report a case of a 49-years-old male who developed weakness of right upper and lower limb slurring of speech with facial asymmetry following Russell's viper bite. Magnetic resonance imaging of brain revealed infarct in the left middle cerebral artery territory. The possible mechanisms for cerebral infarction in this scenario are discussed, which were hypotension


Analysis of biological sequence data demands more and more sophisticated and fine-grained models, but these in turn introduce hard computational problems. A class of probabilistic-logic models is considered, which increases the expressive power from HMM's and SCFG's regular and context-free languages to, in principle, Turing complete languages. In general, such models are computationally far too complex for direct use, so optimization by pruning and approximation is needed. The first steps are made towards a methodology for optimizing the models by approximations using auxiliary models for preprocessing or splitting them into submodels. An evaluation method for approximating models is suggested based on automatic generation of samples. These models and evaluation processes are illustrated in the PRISM system developed by other authors.


Current emphasis on elimination of the HIV/AIDS epidemic challenges researchers to assess the efficacy of alternative treatment modalities. Previous studies have been conducted using different silver preparations such as silver nitrate (AgNO 3 ) and silver oxide hydrosol (Ag 4 0 4 ) to treat HIV/AIDS patients. These studies did not use nanoparticles and used small sample sizes. Nanoparticle preparations hold particular promise because of their ability to enhance surface coverage. The present investigation is designed to test the efficacy of silver nanoparticle preparations using a pretest- posttest methodology. This research proposal is intended to increase awareness of a complimentary approach to HIV treatment and to stimulate future silver nanoparticle research.


A considerable number of investigators hold that movement in Ameba is produced exclusively by changes in surface tension. Among the most prominent of these we may mention Biitschli (1892), Ryder (1894), Jensen (1905), and Verworn (1909). Many others, e.g., Rhumbler (1910) and McClendon (1911), hold that while surface tension may not be the only factor involved in the process in question, it certainly is one of the most important. The results of our observations do not support these contentions. Certain amebae at times feed almost exclusively on rotifers, at others they feed largely on paramecia. They capture the rotifers by flowing around the foot at the point of attachment to the substratum. After they have surrounded the foot they begin to flow out over the body. The rotifer responds by contracting and forcing the ameba back, after which it extends again and theameba again begins to flow out over it, etc. In the meantime the foot begins to digest and gradually the rotifer weakens. Thus they continue sometimes for days before the rotifer is swallowed. The whole process is of such a nature that after observing it we were fully convinced that the force exerted by the amebae was far greater than could possibly be produced by changes in surface tension. The following observations prove this conviction to be correct with reference to the process of feeding on Paramecium. When amebae are feeding on paramecia they assume a sort of mushroom shape with a serrate edge consisting of numerous short pseudopods. The paramecia tend to come to rest between and under these pseudopods by which they are usually surrounded, but sometimes the ends of the pseudopods approach each other before they are fully extended and cut the paramecium in two. This process requires approximately only ten seconds. To cut a paramecium in two with a fine glass fiber it requires a pressure of approximately 9 mgm. Consequently, if the pseudopods have the same cutting quality as the glass fiber and if their movement is due to a change of surface tension, it would require, to perform the work involved, a reduction in surface tension of at least 1118 dynes per centimeter at the tips of the pseudopods. But if the pseudopods fuse along the edges near the ends so as to form a ring around the para188

PURPOSE: A wide viewing angle liquid crystal display device is provided to enlarge a viewing angle by differentiating the arrangement of liquid crystal molecules at both bent portions of an electrode and compensating the retardation of a light. CONSTITUTION: A wide viewing angle liquid crystal display device includes a first and a second substrates facing each other, a liquid crystal material layer implanted between the first and second substrates, and at least two linear electrodes(33,43) formed on the first and second substrates parallel to each other. Each electrode is composed of a first and a second parts non-parallel to each other. The electrodes cross to each other along the line and row of a pixel and form a gear shape along the row of the pixel. Upon applying voltage to the electrodes, a parabolic electric field drives liquid crystal molecules. Since the electrical fields at both sides of the two electrodes are symmetric to each other, the liquid crystal molecules are arranged symmetrically. Optical characteristics in both regions are compensated with each other. Therefore, a wide visual angle is obtained.


Image semantic retrieval has been a crux to bridge "semantic gap" between the simple visual features and the abundant semantics delivered by a image. Effective image retrieval using semantics is one of the major challenges in image retrieval. We suggest a semantic retrieval and clustering method of image using image annotation user interface. And also design and implement a image semantic search management system that facilitates image management and semantic retrieval, which fully relies on the MPEG-7 standard as information base, and using a native XML database, which is Berkeley DB XML.


Purpose of study Medical School admissions committees often use the selectivity of an applicant's premedical college as a competitive admissions factor. Barron's Profiles of American Colleges publishes an annual selectivity index, ranking pre-medical undergraduate institutions into nine groups, from non-competitive to most competitive, based on each school's average acceptance rate and the average student standardised test scores, high school class rank, and high school GPA. Our goal was to determine whether the Barron's selectivity index could be used as a predictor medical student success. Methods used Utilising student metric data stored in WesternU's central database, 2746 medical student records over 12 years were grouped into one of nine Barron's categories. Relative medical school performance was compared, as measured by the medical student's preclinical grade point averages and their performance on national licensing exams. Summary of results When comparing the nine cohorts, we found no statistically significant differences in the pre-admissions GPA between the cohorts. In addition, when comparing these same cohorts' performance in medical school, we also did not find any significant difference for their preclinical GPA nor any difference in performance on the three levels of national licensing exams (e.g. COMLEX-USA level 1, 2 and 3). Conclusions When comparing selectivity of student's pre-medical colleges as defined by the Barron's selectivity rankings, there is no observable statistical difference in medical school performance. Our study suggests that Barron's selectivity index does not reliably predict medical student success and therefore, it may not be appropriate to consider Barron's selectivity index as a competitive factor for admission into medical school. Because of some potential confounding factors associated with this study, further investigation may be warranted.


A contrast agent during the execution of the ultrasound imaging to operate in acoustic radiation force (42). Continuous wave acoustic radiation force is transmitted (42). Pulse wave of imaging at substantially the same time is sent (44). Using continuous wave and pulsed wave to a low mechanical index, it is possible to increase the coupling efficiency of the treatment target tissue drug containing contrast agents. The effect of the continuous waves for imaging (48) by the pulse wave may be used various techniques to minimize. Acoustic radiation force is sent along with the amplitude profile (42) and / or unfocused or defocused.


1. The effects of nerve stimulation and of adrenaline administration have been studied on the auricle of the frog and the nictitating membrane, gut, and blood-pressure of the cat.

2. The summation effects observed with stimulation at varying frequencies can be explained on the assumptions that a mediator is liberated, that it is destroyed in the tissues and that the course of destruction approximates to that of a monomolecular reaction.

3. The shortest time for half-destruction calculated is 5 secs.

4. The durations of the responses to nerve stimulation indicates longer times for half-destruction than those calculated from the sum-mation of stimuli at varying frequencies. Lag in the response of the tissue is likely to affect duration more than summation, and hence the times calculated from summation experiments are regarded as the more probable.

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Worldwide email is a common and fast communicating way and relatively low sending cost for message transfer protocol. But sometimes without filtering mail box are fill-up with unsolicited bulk email and junk email that is known as spam email. Many financial transaction and electronic business contribute or promote their business through email, which is very annoying to users. The use of spam email is rapidly increasing day after day. For that reason, filtering is essential and popular one to stop spam email. ML approaches are given more successful rate to filtering the spam email. In our paper, we give an overview some of ml classification algorithms as K-Nearest Neighbor (KNN), Naive Bayes (NB), Support Vector Machine (SVM), Logistic Regression (LR), Random Forest (RF), Multilayer perception (MLP) are used for learning the features of spam emails. By using the confusion matrix on 10-fold crossvalidation in this paper to compare the performance of those six ML classifiers based on accuracy, recall & precision. The main goal of this article is to determine the better spam classification techniques for spam detection.


. In this paper, we reexamine the concept of firmly nonexpansiveness in the modular sense in the variable exponent sequence spaces (cid:2) p ( · ) . In particular, we extend the classical fixed point results for firmly nonexpansive mappings defined in Banach spaces to the modular case within the spaces (cid:2) p ( · ) .


In order to carry out the valuation process for a SME family business which belongs to Colombian Poultry Industry, is necessary to adjust some variables of financial models that reflect the multiple risk factors, as well as the socio-economic and political situation in Colombia, in addition to the impact of United States Free Trade Agreement-FTA. Thus, this thesis will serve as a reference for other small business and/or family companies that are under similar conditions, since it is necessary to implement models enabling to support decision-making strategy to deal with the challenge that demands FTA in terms of economic profitability and financial viability.


Abstract In surveying finite populations, the simplest strategy to estimate a population total without bias is to employ Simple Random Sampling (SRS) with replacement (SRSWR) and the expansion estimator based on it. Anything other than that including SRS Without Replacement (SRSWOR) and usage of the expansion estimator is a complex strategy. We examine here (1) if from a complex sample at hand a gain in efficiency may be unbiasedly estimated comparing the "rival population total-estimators" for the competing strategies and (2) how suitable model-expected variances of rival estimators compete in magnitude as examined numerically through simulations.


Abstract : African American cigarette smokers have higher rates of lung cancer and lower rates of smoking cessation compared to Whites. African American smokers also live in communities that have a disproportionately high number of tobacco cues and advertisements. Exposure to smoking cues may promote smoking and undermine cessation attempts. While it is difficult to modify the number of smoking cues in the environment, it may be possible to reduce attention to those cues (attentional bias). This procedure is termed Attentional Retraining (AR), which trains smokers to attend away from smoking cues. AR may reduce exposure to smoking cues, and therefore reduce craving and smoking. The current study examined the efficacy of AR administered on a mobile-device in reducing attentional bias, craving, and smoking.


We theoretically study the role of enzyme-induced bending in DNA-cleavage processes. In our model the enzyme bends DNA at its adsorption site leading to stress propagation along the filaments. Since this process is slow the time-dependent DNA-shape can be calculated in a quasistatic approximation. This allows to determine the range of parameters for which strong DNA bending occurs. For enzymes which cut by bending only the cleavage rate is found to depend crucially on the viscosity of the surrounding fluid and the length of the cut DNA segment.


Among schemes for secret reconstruction, the Lagrange interpolation formula plays a crucial role in Shamir's (k, n) threshold sharing scheme. Here, we investigate the associated polynomial evaluation over finite fields. In so doing, we point out that any misunderstanding of the use of finite fields, as done in some recent work, may lead to errors in the polynomial evaluation over finite fields, thereby resulting in failure for secret sharing.

Correspondence: Maria Aparecida Medeiros Barros do Prado – Universidade Estadual de Campinas, Departamento de Saúde Coletiva, Caixa Postal 6111, Campinas-SP, Brasil. CEP: 13083-970 E-mail: email@example.com Abstract Objective: to estimate the prevalence of use of psychotropic medicines and associated factors in adults and elderly, and to identify the main classes used. Methods: cross-sectional population-based study, conducted in Campinas-SP, Brazil (January/2008-April/2009); chi-square Rao-Scott test and Poisson multiple regression were applied. Results: the study included 2,472 individuals and the prevalence of use of at least one psychotropic medication in the three previous days was 6.8% (95%CI 5.5;8.1); in the adjusted analyses, there were positive associations between use and female sex (PR=1.48; 95%CI 1.01;2.18), worse health perception (PR=2.10; 95%CI 1.13;3.89), common mental disorder (PR=1.66; 95%CI 1.09;2.51) and emotional problems (PR=8.04; 95%CI 4.87;13.02); black/brown-skinned individuals presented significantly lower use (PR=0.58; 95%CI 0.39;0.88); antidepressants (52.6%), anxiolytics (28.1%) and antipsychotics (17.0%) were the most used. Conclusion: inequalities regarding sex and ethnicity/skin color were observed; the findings contribute to the evaluation of the rational use of these drugs.


By combining a high-resolution image from a standard camera with a low-resolution wavefront measurement from a Shack-Hartmann sensor, we numerically reconstruct a high-resolution light field. We experimentally demonstrate the method with a commercially available microscope.


Introduction: Oncologic proximal femoral resection and reconstruction in skeletally immature children remains a formidable task due to the risk of developing hip instability with patient growth or interval leg lengthening through the prosthesis. Shelf pelvic osteotomy increases femoral head coverage and containment, and favorable long-term results have been reported in the setting of developmental dysplasia of the hip and Perthes disease. We present a technique of combining shelf osteotomy with expandable proximal femoral endoprosthesis reconstruction in pediatric limb-sparing surgery. Materials and Methods: Four surgeons at 2 centers from 2012 to 2020 performed proximal femoral reconstruction with shelf osteotomy. Data were collected retrospectively on operative technique, radiographic measurements, and complications including dislocation, subluxation, implant loosening, pain, function, and radiographic outcomes. Results: Five patients were included in the study. The mean follow-up was 49 months (range: 17 to 104 mo). The mean lateral center edge angle status postproximal femoral resection and reconstruction shelf osteotomy was 56.1 degrees (±30.5). There were no reported incidences of subluxations, dislocations, periprosthetic fractures, or soft tissue complications. The 3 patients with the longest follow-up at 3, 5, and 8 years tolerated serial lengthening of the endoprosthesis totaling 1 cm, 7.25 cm, and 9 cm, respectively, and demonstrated earlier triradiate cartilage closure in the operative side compared with the nonoperative side. All patients have returned to independent ambulation. Discussion: Combining proximal femoral reconstruction with shelf osteotomy in limb salvage pediatric orthopedic oncology may help to improve hip stability with serial lengthening and patient growth.


The performance of carboxylic acid functionalized carbon nanotubes (CNTs(COOH)), chitosan (Chit), carbon nanotubes-chitosan (CNTs-Chit and CNTs(COOH)-Chit) for immobilizing of amino-functionalized ssDNA and fabrication of electrochemical prostate specific antigen (PSA) aptasensor were studied in detail using X-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and electrochemical impedance spectroscopy (EIS). The assemblies of capture probe are formed on the surface via two approaches: EDC/NHS chemistry and glutaraldehyde linker. Cyclic voltammetry (CV), differential pulse voltammetry (DPV) and EIS techniques were used to investigate the analytical performance of the PSA aptasensor. Under optimum conditions the sensitivity of 0.0026 µA/(ng/ml) and a limit of detection of 0.75 ng/ml (22 pM) were obtained for PSA detection. This protocol offers a new means for sensitive detection of PSA with some advantages in terms of simplicity, selectivity, ease of use and regenerability.


Th e aim of the study was the comparison of serum concentration of infl ammation biomarkers of patients with COPD and chronic not obstructive bronchitis and to assess biomarkers level depending on clinical-functional features of COPD. In 59 outpatients (50 with COPD and 9 with chronic bronchitis) serum concentration of infl ammation biomarkers (IL-6, IL-8, TNF-ƒ, CRP) was analyzed. Results showed essential distinctions of infl ammation intensity in COPD vs. chronic bronchitis patients. Th e concentration of biomarkers in COPD patients with bronchial hyperreactivity (BHR) was considerably higher as compared with COPD patients without BHR and chronic bronchitis patients. Th us, COPD alongside with local chronic infl ammation is characterized with the expressed systemic infl ammation, especially in COPD patients with BHR.


The wobble performance of cone-shaped target with its micro-Doppler signature is researched in this paper.After the interrelated concepts and signal model of micro-Doppler are introduced,the wobble model of cone-shaped target is built,and the theoretical formula of its micro-Doppler is derived separately with the algebra and matrix methods.By the simulation,the micro-Doppler modulation induced by wobble is extracted successfully from the radar echo with time-frequency analysis method,which agrees well with the computing result,and suggests that the wobble model of cone-shaped target and the mathematical derivation of its micro-Doppler theoretical formula are valid.Besides,the influence of velocity and acceleration on micro-Doppler is researched as well as the request of micro-Doppler on the radar return time and illuminating time,and the research results are valuable for the extraction of micro-Doppler.

Flexible size lot-splitting method,for multi-objective flexible Job-Shop scheduling problem,may produce irregular lot-splitting scheme.To resolve this problem,proposed the idea of regular lot-splitting.According to the rule of maximum batch size,it analysed the main factors which determined the best batch size.It presented a lot-splitting scheme that determined batch size by process time of each job.Experiment shows that main indexes of the scheme with different batch size,including make span,are better than one with same batch size,and the scheme can provide reference for production practice.


In the article An Analysis of Decommissioning Cost Estimates for Nuclear Operating Plants, Richard R. Buta and Robert E. Palmer presented a comprehensive summary of considerations of developing up-to-date estimates of nuclear power plant decommissioning costs (Public Utilities Fortnightly, July 19, 1984, pages 47-49). However, Mr. Pilalis says, this summary focused exclusively on the factors that can affect increases in decommissioning costs at higher rates than the escalation rates of conventional cost indices. In his opinion, Buta and Palmer omitted any consideration of the following two areas that affect both the updating and the development of nuclear power plant decommissioning cost estimates: (1) developments in the areas of technology, operational experience, financing, and regulation of nuclear power plant decommissioning that could lower nuclear decommissioning costs and retard the escalation rate of individual decommissioning cost categories; and (2) inclusion of sizeable contingency factors in cost estimates that intend to address the uncertainty of future events in the operational and regulatory environment for nuclear power plant decommissioning. 8 references.


paper reports some phenomena on repression of lipase formation and stimulation of invertase formation caused by sucrose during pollen germination. The pollens of Pinus densiflora Sieb. et Zucc. were collected from the anther which was just before dehis cence, and after strage at -20•Ž for about 3months were used for the following investigation. Germination of the pollen was done by incubation at 30•Ž for 5 to 24hr on 3% agar containing or no containing 3% sucrose. Three grams of pollen were suspended in 30ml of 0.1M sodium phosphate buffer (The pH was 7.0 for lipase and 6.0 for invertase) and disrupted with a French Press at 400•`600kg/cm2. To the disrupted mixture was added 30ml of the same buffer solution, and stirred for one hr. The mixture was centrifuged at 15,000•~g for 20min, and the super natant was filtered through a filter paper (Toyo, No. 2). The filtrate was diluted to 100ml with the same buffer to assay invertase and lipase. Their activities examined during germination are presented in Figs. 1 and 2. FIG. 1. Activities of Invertase and Lipase during Germination of Pine Pollen on a Medium Containing No Additional Sucrose.


The scope of the present article is restricted to a few disconnected points concerning the Great Persian War, and its edges have been carefully left untrimmed. Recent publication on the same subject has been so voluminous as to impose conciseness upon future writers; and the success with which many outstanding problems have latterly been discussed, notably by English scholars, leaves a comparatively narrow field for future research. Yet it may be of interest to revert to particular topics which invite renewed consideration, and to reaffirm certain conclusions which appear to be falling into undeserved disrepute.

In the copper–mefenamate complex tetrakis[μ-2-(2,3-dimethylanilino)benzoato-κ2
 O:O′]bis[aquacopper(II)]–1-methoxy-2-(2-methoxyethoxy)ethane (1/2), [Cu2(C15H14NO2)4(H2O)2]·2C6H14O3, the asymmetric unit comprises a CuII cation coordinated to two mefenamate ligands solvated with a water molecule and a diglyme molecule. The complex adopts a paddlewheel motif and is compared to structural analogues crystallized with dimethylformamide and dimethyl sulfoxide.


As the head-disk spacing is locally reduced to a few nanometers by the introduction of thermal fly-height control sliders, the instability of the flying slider at disk proximity and the detection of slider-disk contacts are of fundamental importance. Slider-disk contacts have been reported in several component-level experimental studies by observing an increase in averaged acoustic emission or laser Doppler vibrometry signals. In this paper, we investigate the transient slider dynamics at multiple locations on a slider body to study the instability from the conditions of disk proximity to light contacts. We define the onset of contact using the pattern transitions of acoustic emission signals, and we study separately the instabilities at the slider's trailing edge center (TEC), leading edge center (LEC), and down-track direction (DTD). The results show there is an evolution of slider instability that occurs during the transition from flying to contacts. Slider dynamics modulation in the DTD are more sensitive to the onset of contacts than at the LEC, whereas the dynamics at the TEC show the least instability. The results suggest that the down-track modulation, which happens prior to a severe TEC modulation, provides a preferred early contact detection criterion that can be used to prevent a more engaged slider-disk contact and mechanical wear.


With the HADES setup the reaction p+Nb was measured in September 2008, where the proton had a kinetic energy of 3.5 GeV ( √ sNN = 3.18 GeV). This rather moderate energy gives us the possibility to study the production and interaction of particles at small excess energies. Studying two-particle correlation functions at small relative momenta provide information about the spatiotemporal extent of the particle emitting source. Originally, the formalism of intensity interferometry was developed for astrophysical investigations to measure the angular size of stars [1]. Nowadays, the technique is mainly applied in the field of heavy-ion physics to gain information about the highly excited matter state and its properties created during the collision of the two nuclei. The basic idea of femtoscopy is to deduce effects of final state interactions (FSI) from phase-space correlations of emitted particles. In low energy p+A systems we expect no contributions from collective effects to the particle emission like flow or energetic jets. Because of this reason, we are in the position to study only FSI of different particle species and do not have to consider effects from physical non-femtoscopic sources. FSI can be studied with correlation functions, which are defined as the ratio of the two-particle probability divided by the uncorrelated probabilities:


This study aims to explain and determine the effect of leadership style, compensation, and work environment on the performance of employees UD.  Fathona Bakey Kec-Gempol. This research is a type of quantitative research with hypothesis testing. The sample used in this study is the entire population of 55 employees of UD.Fathona Bakery. The analytical tool used in this study is multiple linear regression analysis using SPSS version 22 for windows. The primary data in this study were obtained from questionnaires and company archives whose measurements used a Likert scale which were tested for validity and reliability.The results of this study prove that leadership style partially has a positive effect on employee performance. Compensation partially has a positive effect on employee performance. The work environment partially has a positive effect on employee performance. Transformational leadership style, work environment, and work motivation simultaneously have a positive and significant effect on employee performance.


In the field of distributed decision making, different agents share a common processing resource, and each agent wants to minimize a cost function depending on its jobs only. These issues arise in different application contexts, including real-time systems, integrated service networks, industrial districts, and telecommunication systems. Motivated by its importance on practical applications, we consider two-agent scheduling on a single machine where the objective is to minimize the total completion time of the jobs of the first agent with the restriction that an upper bound is allowed the total completion time of the jobs for the second agent. For solving the proposed problem, a branch-and-bound and three simulated annealing algorithms are developed for the optimal solution, respectively. In addition, the extensive computational experiments are also conducted to test the performance of the algorithms.

This paper presents a comparative study of the Genetic Algorithm (GA) optimized PID control with the Pole-Placement method and the PID based control in matlab for stabilizing the pendulum in its upright position. The performances of the designed controllers are studied based on the time domain specifications. The real time Quanser kit is used to obtain the model parameters of inverted pendulum system and then the obtained model is simulated in the Matlab environment. The Pole-placement method is implemented using the design specifications of Quanser kit. Further, the PID based control is implemented using the self-adjusting mechanism in matlab which is compared with the GA assisted optimized PID control.


A wick bioassay was developed to screen peach [Prunus persica (L.) Batsch] shoot cultures for resistance to bacterial spot [Xanthomonas campestris pv. pruni (E. F. Sm.) Dows)]. Three weeks after inoculation, the number of colony forming units (CFU) from 1-cm stem sections excised from highly susceptible cultivars was significantly greater than CFU from several resistant cultivars. Neither growth regulators nor the length of time that shoots were maintained in vitro prior to inoculation significantly influenced the response of these cultivars to bacterial leaf spot. This technique should be useful in screening for somaclonal variants obtained from peach cell cultures.


Aim: A new analytical platform combining ultrasound assisted-dispersive liquid-liquid microextraction (US-DLLME) with thin layer chromatography (TLC)-image processing analysis has been proposed. Materials and Methods: Acetylsalicylic acid (ASA) was selected as the model compound to demonstrate the applicability of the proposed method. The complete analysis comprises of three steps: (i) US-DLLME (injection of extraction and disperser solvent into an aqueous sample, ultrasonication and centrifugation), (ii) TLC of sedimented phase, and (iii) photography of TLC plate followed by quantification of ASA spots using freely available imageJ software (National Institute of Health (NIH), Bethesda, MD, USA). Results: The newly developed method is simple, environmentally benign and does not require any special instrument and handling skills. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.1 and 0.35 μg/spot, respectively. The assay was found to be linear in the range of 1-250 μg/spot with a square of correlation coefficient (R2) of 0.999. Conclusion: The developed method was successfully applied for the analysis of ASA in urine and pharmaceutical formulations. Results of analysis of ASA in commercial aspirin tablets obtained by the proposed method were in close agreement with the results of the UV-Visible spectrophotometric analysis.


We extend the classical results on the symmetry inheritance of the canonical electromagnetic fields, described by the Maxwell's Lagrangian, to a much wider class of models, which include those of the Born-Infeld, power Maxwell and the Euler-Heisenberg type. Symmetry inheriting fields allow the introduction of electromagnetic scalar potentials and these are proven to be constant on the Killing horizons. Finally, using the relations obtained along the analysis, we generalize and simplify the recent proof for the symmetry inheritance of the 3-dimensional case, as well as give the first constraint for the higher dimensional electromagnetic fields.


Energy expenditure and substrate oxidation rate for fat, glucose and protein were evaluated by indirect calorimetry in 20 normal individuals, 35 patients with acute hepatitis and 22 patients with biopsyproven alcoholic cirrhosis in the postabsorptive state. Measurements were done in the resting state after an overnight fast (10 to 12 hr). Oxygen consumption (ml/min/1.73 m2) in normal subjects, in patients with acute hepatitis and in patients with cirrhosis was 206.5 ± 4.0 (mean ± S. E. M.), 216.4 ± 4.7 and 228.8 ± 7.1 (p < 0.05 vs. controls), respectively. When related to body surface area (Kcal/min/1.73 m2), resting energy expenditure did not differ between normal subjects (0.98 ± 0.02), patients with acute hepatitis (1.03 ± 0.02) and cirrhotic patients (1.06 ± 0.03). However, when related to 24‐hr urinary creatinine excretion as an estimate of lean body mass, energy expenditure was in creased in cirrhosis (p < 0.0001). In cirrhosis an inverse association between the severity of liver disease according to Pugh and oxygen consumption and resting energy expenditure was found. In cirrhotic patients the percentages of total calories derived from fat (86% ± 5%), carbohydrate (2% ± 4%) and protein (12% ± 1%) were different from those of normal controls who metabolized 45% ± 4%, 38% ± 4%, 17% ± 1%, respectively. In acute hepatitis no alterations in metabolism could be found apart from a decreased protein oxidation rate.

We evaluated a 22-year-old patient complaining of acute breathlessness and pretibial edema in relapsed and refractory acute lymphoblastic leukemia (ALL). The patient was under rituximab-cyclophosphamide, vincristine, dexamethasone, doxorubicin (R-HCVAD) alternating with R-rituximab, methotrexate-cytarabine (MTX-ARAC) chemotherapies and he had a pancytopenia including severe thrombocytopenia. On his physical examination: The heart rate was 120 beats/min with evidence of pulsus paradoxus and the blood pressure was 85/60 mmHg. The jugular venous pressure was elevated up to the angle of the jaw. The cardiac apex was ill-defined and heart sounds were faint. There was no murmur or pericardial friction rub. He had severe pretibial edema because of hypoalbuminemia and acute right ventricular dysfunction observed by echocardiography. Electrocardiography revealed a poor R wave progression in all precordial derivations and sinus tachycardia. Laboratory data showed haemoglobin of 9.2 g/dL, white blood cell (WBC) count of 2.8x10 K/ uL with 93% blast cells, platelet count of 5x103/uL. International Normalized Ratio (INR) was 2.94 and activated Partial Thromboplastin Time (aPTT) was 56 sec. Chest radiogram showed moderate right sided pleural effusion with a normal cardiothoracic index. Bedside echocardiography revealed a large pericardial effusion with gross cardiac oscillation and diastolic collapse of the right ventricle and atrium (Figure 1). Mitral inflow pattern changed in expirium more than 25% of inspirium values and tricuspid inflow pattern changed in inspirium more than 40% of expirium values. Vena cava size was 2.3 cm and there was no change with respiration, particularly during inspirium. Echocardiographic and clinical findings indicated cardiac tamponade. Despite treatment with R-HCVAD regimen, the patient had no reponse to the treatment and his clinical condition was deteriorated. Because of the patient's hemodynamic instability, we Abstract Cardiac tamponade (CT) as a clinical manifestation of lymphomas is extremely rare. Although leukaemic infiltration of the pericardium is frequently observed at post-mortem, clinically evident cardiac tamponade is also rare. We present a case of cardiac tamponade complicating leukaemia. The patient had cardiac tamponade and severe thrombocytopenia during chemotherapy due to relapsed and refractory acute lymphoblastic leukemia (ALL). We experienced complete resolution of the pericardial effusion without any bleeding complications after urgent pericardiocentesis within 15 days after successful ibubrufen-colchicine therapy. The exciting feature of this paper is that rescue pericardiosentesis may be livesaving despite crucial states, such as severe thrombocytopenia. (JAEM 2012; 11: 188-9)


Pyrophosphate:fructose-6-phosphate 1 -phosphotransferase (PFP) was quantified in developing barley (Hordeum vulgare) leaves by immunostaining on western blots using a purified preparation of barley leaf PFP as standard. Fructose-2,6-bisphosphate (Fru-2,6-bisP) was quantified in the same tissues. Depending on age and tissue development, the concentration of PFP varied between 11 and 80 pg PFP protein g-' fresh weight, which corresponds to 0.09 to 0.65 nmol g-' fresh weight of each of the a and 0 PFP subunits. The level depends primarily on the maturity of the tissue. In the same tissues the concentration of Fru-2,6-bisP varied between 0.07 and 0.46 nmol 8-l fresh weight. Thus, the concentrations of PFP subunits and Fru-2,C-bisP were of the same order of magnitude. In young leaf tissues the concentration of PFP subunits may exceed the concentration of Fru-2,6-bisP. This means that the amount of Fru-2,6-bisP present will be too low to occupy all the allosteric binding sites on PFP even though the concentration of Fru-2,6-bisP exceeds the Ka(Fru-2,6-bisP) by several orders of magnitude. These results are discussed in relation to Fru-2,6-bisP as a regulator of enzyme activities under in vivo conditions.


The right to participate is an essential feature of the right to health as reflected in the WHO constitution.1 Lived experience of individuals with different geographical, cultural, political, economic and social contexts, when meaningfully engaged, is invaluable to understanding barriers, unlocking solutions and enhancing related policies, programmes and services. Individuals with lived experience can also aid in the cocreation of sustainable interventions, accountability and governance processes at the national and regional levels. WHO is developing a framework for meaningful engagement of people living with noncommunicable diseases (NCDs), mental health conditions and neurological conditions to support this essential goal and paradigm shift. It promotes meaningful engagement as essential in responding to the needs of people living with NCDs, such as cardiovascular diseases, cancers, diabetes, chronic respiratory diseases, alongside mental health conditions and neurological conditions. The expertise offered by the lived experience of health conditions can also shape the social, economic and physical environments including addressing related risk factors such as tobacco use, the harmful use of alcohol, unhealthy diets, physical activity and air pollution. It incorporates and promotes bottomup approaches, where lived experience is viewed through an intersectional and equity lens to better understand and address the root causes and management of the health diseases through health systems. We will brief ly highlight the intersectionality of individuals living with dermatological diseases and the lived experiences of the WHO Framework. Reflecting on the Patient priorization of impact items to develop the PatientReported Impact of Dermatological Diseases (PRIDD) measure: European Delphi data, we will draw on the intersectionality on mental health conditions and three priority areas for meaningful engagement: eliminating stigma, promoting diversity and inclusion, and redistributing power.


For reliability design and safety evaluation on fiber wound reinforced plastics (FWRP) pressure vessels,the traditional safety factor design was substituted by a reliability structure design based on the reliability theory and the statistical principle.Eight glass fiber wound reinforced plastics(GFWRP) pressure vessels were manufactured and the experiments were conducted to obtain the probabilistic distribution of design variables,such as the fiber strength,winding angle,geometric size,burst strength and so on.The results(thickness of the winding fiber) derived from the reliability design agree well with the experimental results and much lower than that from the traditional safety factor design.Through comparison between the reliability design results with different statistics of fiber strength,the significant influence of the variance level of fiber strength on reliability design of FWRP pressure vessel was demonstrated.The traditional safety factor design was verified to be not reasonable since it considers only the mean value of fiber strength without the effect of fiber strength statistics on the structural resistance of the vessel.The reliability design of FWRP pressure vessel in this study presents the effective unity of safety and economy.


The author, Dr S. B. Khoo, states that patients with incurable illnesses are "turned away from acute General Hospitals, and are told that there is nothing more to be done". This is untrue with respect to my own experience with lung cancer patients seen in Penang Hospital between 1988 and 2001, when I was the physician in-charge of the respiratory medical unit. The burden on inpatient workload has been documented in a study done on cancer admissions to the hospitaF during the year 1995 which showed that the commonest primary site in inpatients was lung 093/1335, 14.5% of cases). Lung cancer patients accounted for 316/2,947 admissions 00.7%) and 5,796/35,324 inpatient days 06.4%) for malignant disease3• For new lung cancer patients seen between 1995 and 2001 only 67/1,174 had surgery with a view to curative resection (5.7%)4. As of August 2002, the five-year survival was 29%. It can be inferred from this data that almost all lung cancer patients seen were incurable and almost all treatment given during hospital admissions or during outpatient consultations can be considered to fall into the realm of palliative care.

Na/NiCl2 batteries represent a high-energy-density battery concept based on abundant, low cost-materials. The current production process of the solid state electrolyte is the driving cost factor in this field. IKTS develops improved technologies for the highly efficient production of this price-determining core component – the ceramic sodium β-alumina electrolyte. Furthermore, by simplifying the cell design regarding the manufacturing technology, the aimed target costs amount to below 200 EUR/kWh at cell level. Starting with a lab-scale screening of powder synthesis, several routes for electrolyte shaping are under development. Boehmite based β-aluminas reached ionic conductivities of about 0.241 S/cm at 300°C with a highly dense microstructure and a β"-phase content of > 97 %. The powder processing was transferred to pilot scale and different shaping technologies were evaluated. Electrolyte tubes with a length of 30 cm were manufactured by isostatic pressing. For the stiff plastic extrusion the preparati...

ABSTRACT In this article I investigate a decentralized infrastructure meant to assist autonomous vehicles in making decisions. More akin to a call centre than a centralized control room, Nissan's 'Seamless Autonomous Mobility' (SAM) project imagines that remote 'mobility managers' will intervene in the decision-making of autonomous vehicles, with the assistance of live video streams and other sensor data. Different from other kinds of AI microwork in which human workers prepare, imitate, or verify AI, mobility managers are envisioned instead as 'interveners', meant to directly and actively intervene in the movements of 'autonomous' vehicles when unable to negotiate an obstacle. Firstly, through a comparison between SAM and a traffic management system in Los Angeles, I argue that the former 'normalizes' intervention, in which decision-making delays become ordinary, if not altogether desirable. Secondly, through an analysis of a video in which such normalized interventions are imagined, I consider how SAM offers a kind of speculative mundanity in which remote workers, enabled by a technological infrastructure, embody a novel logic that modifies the social settings of driving.


This article explained how early interventions and clinical input from stroke specialists and multidisciplinary teams can save lives and prevent further damage to the brain following stroke. Nurses have an important role in ensuring that stroke patients are seen promptly during triage.


Objects associated with image data are associated with one another in the form of a tree structure which comprises nodes representing the objects, sequence values are assigned to child node groups of respective parent nodes, image data on objects of interest are divided into layers on the basis of the depth of the tree structure in a partial tree obtained by tracing back from the node for each object of interest to the root node and the sequence value assigned to each node, and an image is generated by superimposing the layers upon one another.


Measuring student readiness in online learning should also be of great concern to institutions, including all areas from their curricular development to the pedagogies they experience. Although there have been attempts at universities to develop online learning courses, students' readiness has yet to be investigated, particularly for engineering students who take a mix of theoretical and practical-based courses. This study evaluates the readiness of civil engineering students toward the implementation of online learning and their preferences and acceptance towards online instructional delivery and assessment methods. Ways for improvement are proposed in line with the students' readiness to determine the best desirable practices and strategies for online pedagogy. Respondents are selected from first and final year students, to examine and compare their online learning perspectives. A survey questionnaire was used. Findings revealed that year one and year four students' readiness were relatively moderate for most of the components and relatively high for the components that involved hardware/software requirements and technology skills. Most respondents indicated a moderate acceptance level on online assessment, ranging from a mean score of 3.46 to 3.81. As online learning is gradually becoming another method for life-long and self-determined learning, findings from the study might help university educators to develop better online learning strategies, especially delivery methods and assessments, to help students cope with online learning.


Investigates the relationship between the milling parameters and the surface residual stress in high speed milling the high hardness and strength alloy steels.Experiments on the cutting temperature and cutting force of high hardness and strength alloy steels were carried out in high speed milling.Rules of influence of milling parameters on the average milling temperature and milling force were studied,and empirical formulas of the temperature and milling force with the milling parameters were established,and the effects of cutting force and cutting temperature and the microstructure caused by the cutting temperature on the residual stress were also analyzed.The results show that the surface residual stress exists obviously in high speed milling the high hardness and strength alloy steels.Compressive residual stress is generated in the selected parameters range,and the main reason that the compressive residual stress is generated is the cutting force and the microstructures changes of the degenerative layer caused by the cutting heat.And with the increase of the cutting speed,the residual stress becomes larger and the depth of the metal with residual stress becomes larger too.


Herein, electron paramagnetic resonance (EPR) spectroscopy at X- (9.4 GHz), Q- (34 GHz) and W-band (95 GHz), and superconducting quantum interference device (SQUID) measurements on antiferromagnetically coupled metal trimers in MIL-101(Cr) and MIL-100(Al_{0.8}0.8Cr_{0.2}0.2) MOFs were investigated. At low temperatures, the Cr(III) trimers exhibit a Dzyaloshinsky-Moriya (D-M) interaction, and have a total spin state S_T = 1/2T=1/2.

We calculate the reflectivity of light incident upon the exposed face of a semi-infinite crystal, using the point-dipole model. This requires an accurate solution for the polariton modes near the crystal surface. The variation of the Lorentz local field, caused by the surface, is included in the calculations. The boundary conditions for the polariton modes are derived rigorously. This represents the first rigorous microscopic solution of polariton modes near ideal surfaces.


The influence of growth temperature on the optical properties of CuInSe2 thin films producing sputtering targets of different compositions is presented. CuInSe2 films exhibited direct allowed transitions with values ranging between 0.9 and 1 eV depending on substrate temperature. Additional direct forbidden transitions, ranging between 1 and 1.22 eV, are also observed. A clear correlation is observed between crystallinity and optical gap. On the other hand, film composition, in the range analyzed, did not show influence over optical properties.


SIR HUGH CAIRNS'S greatest contribution was undoubtedly the organization of care for patients with head injuries during World War II. This included the keeping of careful notes as a basis for subsequent reviewof the results, in order to formulate a future policy-, This was in the tradition of Harvey Cushing, whose pupil Cairns was, and who had given similar leadership during World War I. As a pupil of Cairns myself, I should like to think that the work reported here might be seen as a logical continuation of his concern with the problem of head injury. Two statements made by Cairns in his account in 1947 of the war experience provide a text for this lecture. He wrote;'


ABSTRACT Short alanine (Ala) oligopeptides in aqueous solution adopt polyproline II [PPII; (φ, ψ) = (−60°, 150°)] and extended β conformations [(φ, ψ) = (−150°, 150°)], whose conformers are related to the denatured state of proteins. In this study, we investigated pressure-induced conformational changes of penta- and hexa-alanines (Ala5 and Ala6, respectively) in aqueous solutions using Fourier-transform infrared (FTIR) spectroscopy. A remarkable observation was that two peaks at 1620 and 1690 cm−1 in Ala6 assigned to the intermolecular β-sheets were generated with increasing pressure. These peaks were not observed in Ala5. Our analyses of absorbance changes and frequency shifts further suggested that pressure was responsible for the PPII → β conformational change of Ala5, and the PPII → intermolecular β-sheet structure of Ala6, respectively. These results indicated a differing conformational stability of Ala5 under high pressure as compared with Ala6.
