Absorption coefficient is an important parameter for reservoir description. The major troubles in extracting absorption coefficient from seismic data are amplitude and waveform distortions; they greatly restrict the inversion which is based on reflection amplitude variation or reflection frequency variation. This paper presents a new method which avoids amplitude and uses waveform variation gradient in wave propagation to make the inversion of absorption coefficient. Apparent absorption coefficient and pseudo absorption coefficient are adopted so as to remove the influence which the waveform distortion due to thin bed tuning brings to absorption coefficient extraction. The final instantaneous equivalent absorption coefficient, a true absorption coefficient which reflects real absorptive character of a seismic medium, can be obtained by subtracting the pseudo absorption coefficient (inversely calculated using maximum entropy) from the apparent absorption coefficient the authors have calculated.


A positive feedback solution for flex pivot-mounted gimbal stabilization systems is discussed. The solution implements band-limited derivative control to compensate for the flex-pivot resonance while minimizing the bandwidth to 2.0 Hz for an additional 11 dB of attenuation above 3 Hz. Tradeoff study results are discussed, and a closed-form solution is presented which solves for the compensator parameters as a function of flex pivot stiffness, plant characteristics, and desired bandwidth.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering.

The purpose of the health care system in a country is to correctly diagnose the disease, identify the factors responsible for the disease and take appropriate preventive and curative measures to control the disease. The pathologists and laboratory people are very much involved in the correct diagnosis, effective treatment and follow up of the patients. For correct diagnosis quality assurance and quality control are very important. A test wrongly done is worst than a test not done. Quality control is the process to ensure prevent a test from being done wrongly. Laboratory quality control is designed to detect, reduce and correct deficiencies in laboratories analytical process to release patient results and improve the quality of test result.


Based on the massive advancements in modern hardware technologies, beyond high-resolution images, immersive and interactive videos have become an important next-generation technology. Immersive video includes 3D information having a huge number of bits. Thus, a special coding standard is required to compress immersive video e.g., 360 and point cloud videos. To compress immersive videos, the 3D information is projected into 2D space which creates several empty spaces called inactive regions. Even though the codec model can efficiently compress the immersive video, the inactive regions excessively degrade the overall performance. Recently, several model-based methods have suggested filling the inactive regions to prevent performance degradation. In this paper, we propose a novel approach to fill the inactive region using deep reinforcement learning. We perform block-wise inactive region filling in which each block has an agent, and overall pixel values are controlled by using a control point-based block-wise selective filtering method. The control point controls the pixel intensity to generate rough patterns and reduce computational complexity. In addition, each control point and the active region (attribute or pixel information) are propagated to the inactive region by considering their own information and neighboring information. Besides, each agent can learn the information of neighboring blocks with a modified rate-distortion (R-D) cost reward. We evaluate the proposed method on the sphere segmented projection (SSP), point cloud compression (PCC) attribute, and PCC geometry video formats. The proposed method achieves an average bitrate reduction of −10.9% for the SSP, −9.1% for the PCC-attribute, and −11.8% for the PCC-geometry, which are much better than the conventional method.


Ternary systems, such as alcohol. water, and sodium hydroxide, have been used in the pretreatment bath or have been added in fixed quantities to cotton prior to etherifi cation with benzyl chloride. Evidence has been obtained which supports an hypothesis that increased reagent solubility, coupled with control of the cellulose: sodacellulose equilibrium. can lead to essentially homogeneous cotton cellulose modifications. In addition, the experiments have resulted in the preparation of interesting fibrous cellulose ethers. These ethers retained many of the desirable mechanical properties of the original cotton and showed increases in elastic recovery, decreased permanent set, sub stantivity to disperse dyes, microbiological resistance, and a high degree of thermo plasticity.


Human anti-IgE autoantibodies have been identified and implicated in the regulation of IgE-mediated reactions and IgE synthesis. In order to study the potential regulatory role of anti-IgE antibodies on IgE binding to the FceRII we used a panel of IgE-specific monoclonal antibodies that were mapped by Western blotting against a series of recombinant e domain peptides. Antibodies specific for all e domains were detected except those against CeHl. Using a competitive inhibition cell-binding assay on FceRII + 8866 cells, we identified two major patterns of anti-IgE activity. Antibodies specific for the CeH3 domain removed IgE whereas those specific for the CeH2 domain enhanced IgE binding to the FceRII. The anti-CeH2 antibodies, in contrast to the anti-CeFD antibodies, could not dissociate cell-bound IgE from the FceRII. Using preformed immune complexes of IgE and anti-IgE antibodies, it was clear that the anti-CeH2 antibodies bound more IgE to the FceRII by addition of immune complexes to the cell surface. Our results suggest that the opposing actions of either inhibition or enhancement of IgE binding by anti-IgE antibodies are related to their e domain specificity.


Nowadays, user is provided with many contents, which the previous search engines failed to find, thanks to various recommendation systems. These recommendation algorithms are usually carried out using collaborating filtering algorithm, which predicts user's preference, or contents based algorithm, which calculates on the basis of the similarity between contents. In addition to the above algorithms, many algorithms using user's context have been recently developed. Based on the previous researches, this paper proposes a new system to categorize contents information into various factors and learn user's selection. First, we divide information of items into four types and make user preference pattern using each information type. The information types can express more various user preferences and user preference pattern can calmly deal with user preference. Then, we calculate the score for recommendation using user preference pattern. That is, our system is constructed on these three modules: item analyzing module, user pattern analyzing module and recommendation score module. Lastly, we provide entire system flow to show how they work. Keywords-Recommend method; Learning algorithm; User Preference; Recommendation system.


Using a representative panel of manufacturing fi rms, we estimate the response of job and hours worked to currency swings, showing that it depends primarily on fi rms' exposure to foreign sales and their reliance on imported inputs. We also show that, for a given international exposure, the response to exchange rate fl uctuations is magni fi ed when fi rms exhibit a lower monopoly power and when they face foreign pressure in the domestic market through import penetration. The degree of substitutability between imported and other inputs and the distribution of workers by type introduce additional degrees of speci fi city in the employment sensitivity to exchange rate swings. Moreover, we show that episodes of entry and exit in the export market are associated with a heterogeneous employment response depending on the degree of external orientation when the switch of export status occurs.


Mungbean varieties possessing characteristics of early maturing (55-65 days), drought tolerance, and adaptive on less fertile soil, are considered as having good potential to be developed in the sub-optimal farm lands. The other advantage of growing mungbean, it is complementary with rice nutrition, by which rice protein is enriched by a rich mungbean lysine. At the farm level, mungbean can improve farmers' nutritions and income. Mungbean crop in Indonesia covers 297,315 ha with the total production of 341,342 ton and the productivity of 1.15 t/ha. The mungbean production centers include Central Java, East Java, West Nusa Tenggara, South Sulawesi, West Java and East Nusa Tenggara, where they contribute around 91.7 percent to the national production. Variety is a component technology which is easily adopted and safe for the environment. Planting high yielding mungbean varieties had proven to increase the grain productivity in most areas. Types of varieties preferred by farmers varied among regions. The availability of many high yielding mungbean varieties, therefore, allow farmers to select the most suitable ones for their environment. However, not all released varieties had been planted by farmers. The choices of mungbean varieties among farmers generally consider the productivity, consumer preference, and the grain price. Some farmers prefer mungbean with dull seed color while other prefers glossy large or small seeds. The mungbean varieties with small seed, commonly is used for beansprouts. Several mungbean high yielding varieties had been adopted in the farming system of the production centers. Introduction of new varieties with seed characteristics preferred by farmers, followed by demostration plots, and the seed are to be produced by local seed producers are strategy for accelerating the adoption of new varieties.


1.0at% Nd:YAG polycrystalline ceramics were fabricated with different sintering adds by solid-state reaction and vacuum sintering method. The optical transmittance spectra of the samples were measured using V-570 UV spectrophotometer. The microstructure and the grain size of the samples were characterized by Scanning electron microscope. It is found that the sample with 0.5wt% SiO2 and 0.5wt% MgO had the best transmittance, the most densification and uniform grain size, and the grain size decreased with the increasing MgO. Effects of MgO on the microstructure of YAG and its action mechanism have been investigated.


The reduction in viscosity of Automatic Transmission Fluids (ATFs) for improving fuel economy results in a reduction in transmission gear fatigue life due to occurring pitting. The aim of this study is to establish a suitable test condition for evaluating differentiation in the gear pitting life between ATFs by using a Forschungsstelle fur Zahnrader und Getriebebau (FZG). In this study FZG gear sets were modified so that gear teeth were misaligned and the contact tooth width was shortened by offset in the direction of the shaft. The fatigue pitting life in response to ATFs under this modified FZG test condition was of the same order as that obtained in the actual transmission test under a severely offset condition. A sulfur-containing additive could play a role on the gear tooth life under severe condition, which was most likely attributed to tribofilm for motion on the gear tooth surface.Copyright © 2011 by ASME


Underground tunnels are considered to be a vital infrastructure component in most cities around the world. Careful planning is always necessary to ensure minimum impact on nearby surface and subsurface structures. This study describes the experimental investigation carried out to examine the effect of existing piles installed in cohesive soil and extended to bedrock on the circumferential stresses developing in a newly constructed tunnel supported by a flexible lining system. A small scale testing facility was designed and built to simulate the process of tunnel excavation and lining installation in the close vicinity of preinstalled model piles. Lining stresses were measured for different separation distances between the lining and the existing piles Consistent decrease in the lining load was observed when the piles are located within a distance of one tunnel diameter from the tunnel. The results presented in this study indicated that measuring the lining response near existing pile foundations may be used to evaluate the extent of the interaction between the lining and the surrounding piles.

Based on the results of thermal-hydraulic analysis, the blanket melting frequency has been calculated and compared with the core damage frequency of PWRs and a fast reactor. Simple sensitivity analysis has been performed as well.


In this conversation essay, the authors incorporate teaching assistants (TAs) into pedagogical theorizing through what they call the teaching triad, an analytic heuristic to understand faculty-TA-undergraduate interactions. TAs are graduate students who are tasked with running discussion sections, smaller settings where undergraduates interact more directly with the material and one another. Yet, faculty pedagogies enable or constrain the work of TAs and shape classroom climates. We discuss three types of faculty pedagogies and their effects: (1) authoritarian pedagogies, wherein faculty exhibit inflexible, controlling behaviors that create a silencing and distrustful climate; (2) absentee pedagogies, characterized by a lack of faculty presence, which results in additional labor for TAs and confusion and panic for students; and (3) advocate pedagogies, which involve proactively engaged and flexible faculty approaches, cultivating an empowered environment. Understanding these dynamics is important for first-generation and/or working-class students, particularly those of color, who already face barriers to learning.

Abstract The present paper investigates the transverse vibration of a non-uniform axially functionally graded Timoshenko beam with cross-sectional and material properties varying in the beam length direction. The Chebyshev collocation method is used to spatially discretize the governing partial differential equations of motion of the beam into time-dependent ordinary differential equations in terms of Chebyshev differentiation matrices. An algebraic eigenvalue equation in matrix form is then formed to study the free vibration behavior of non-uniform axially functionally graded Timoshenko beams. Several results of natural frequencies of the beams are evaluated and compared with those in the published literature to assure the accuracy of the proposed model. The effects of taper ratio, material graded index, slenderness ratio, material compositions and restraint types on the natural frequencies of tapered axially functionally graded Timoshenko beams are examined.


The aim of the present systematic review and meta-analysis was to examine the long-term effects ( ≥ 12 months) of high-fat (HF) v. low-fat (LF) diet consumption on the indicators of glycaemic control as well as cardiovascular risk factors in pre-diabetic and diabetic individuals. Literature search was carried out using the electronic databases MEDLINE, Embase and the Cochrane Trial Register until November 2013. Study-specific weighted mean differences (MD) were pooled using a random-effects model of the Cochrane software package Review Manager 5.1 and Stata 12.0 was used for meta-regressions. A total of fourteen trials met the inclusion criteria and a maximum of 1753 subjects were included in the meta-analysis. HF regimens were found to result in a significant decrease in TAG levels (MD − 0·19 mmol/l, 95 % CI − 0·23, − 0·14, P< 0·001; I 2= 0 %, P= 0·58) and diastolic blood pressure (MD − 1·30 mmHg, 95 % CI − 1·73, − 0·87, P< 0·001; I 2= 0 %, P= 0·60) and a significant increase in HDL-cholesterol levels (MD 0·05 mmol/l, 95 % CI 0·01, 0·08, P= 0·01; I 2= 57 %, P= 0·01). In addition, MD in the reductions of fasting glucose levels ( − 0·41 mmol/l, 95 % CI − 0·74, − 0·08, P= 0·01; I 2 = 56 %, P= 0·02) were significantly high in patients with type 2 diabetes adhering to a HF diet. HF and LF diets might not be of equal value in the management of either pre-diabetes or type 2 diabetes, leading to emphasis being placed on the recommendations of HF diets.


This book is the result of a three-year study undertaken by a multidisciplinary working party of the Institute of Medical Ethic (UK). The group was chaired by a moral theologian, and its members included biological and ethological scientists, toxicologists, physicians, veterinary surgeons, an expert in alternatives to animal use, officers of animal welfare organizations, a Home Office Inspector, philosophers, and a lawyer. Coming from these different backgrounds, and holding a diversity of moral views, the members produced the agreed report as a result of detailed and rigorous discussions. The book sets out facts about animal experiments and about animal abilities to experience pain, distress and anxiety. There is a detailed examination of the moral claims related to the benefits likely to accrue from animal research, and of strategies for weighing these benefits against the harm caused to animals, in order to decide whether particular research projects ought or ought not to proceed. This leads to consideration of the statutory and non-statutory controls which safeguard standards in such research. The final section explores a variety of philosophical arguments about the use of animals in research, and offers a philosophical justification for the Working Party's more practical conclusions. Written in clear, nontechnical language, this book is accessible to lay people as well as to scientists. It is the first such document to emerge from a meeting of people with such widely differing views on this highly controversial subject, and represents a major Lives in t he Balance: T he Et hics of Using Animals in Biomedical Research: T he Report of a Working Part y of t he Inst it ut e of Medical Et hics    contribution towards informing and raising the quality of contemporary debate. The book is unique in drawing together material and ideas never before found in one volume. It will interest a broad spectrum of readers, from ethicists and animal rights advocates to scientific researchers and laboratory administrators, along with general readers concerned about this compelling issue.

The link between indirect exposure to disasters via traditional media and the development of post-traumatic stress symptoms (PTSs) has long been a topic of interest in multiple fields. However, it is unclear to what degree existing findings are applicable to social media. We used random forest regression and classification to conduct an exploratory investigation into the association between type of social media use (i.e. active and passive use) and pandemic-related PTSs. Controlling for post-traumatic stress disorder (PTSD) risk factors and exposure to the pandemic, we found an association between passive social media use and high levels of pandemic-related PTSs among individuals who had not directly been exposed to the effects of COVID-19.


Analogism is the essential tool to establish the basic theories of tradition Chinese medicine (TCM) and exerts a great influence upon the formation and development of TCM basic concepts and its system. On this paper, its definition, cognitive progress and TCM linguistic characteristics under its influence are all analyzed and demonstrated from the perspective of metaphorical theory. Based on the theoretical analysis, it's suggested that literal and free translation should be adopted conditionally concerned on different target text of analogism. So is the specific translation techniques.


This thesis explores the ways in which museums are visited by desiring adolescent subjects in literature. Arising from a process of anthologising museum visitation narratives, this study identifies that their protagonists are often adolescents in crisis. Adolescence is developed in the analysis as being not necessarily a category of age, rather a state of being an open structure that seeks ways and means to reorganise subjectively. It is a positive exploration of the non-work of the delinquent in annexed or repurposed transitional public space of a mnemo-mythological order.


* Corresponding author:Rahman Soori E-mail:firstname.lastname@example.com Backgroundm: Zinc-Alpha 2-Glycoprotein (ZAG) has recently been implicated in the regulation of adipose tissue metabolism due to its negative association with obesity. The purpose of the present study was to investigate the effect of eight weeks of high intensity interval training on the level of ZAG in plasma and adipose tissue in obese male rats. Methods: In the current experimental study, 21 male rats were divided into three groups of sham control (healthy), control (obese), and interval training (obese with training). The training group received eight weeks of training sessions each with 5-12 repetitions of high intensity training for 15-30 seconds at the speed of 27-34 meters per second on a treadmill followed by one minute of active rest. Then, 24 hours after the training sessions, blood and body fat samples were obtained to measure ZAG levels. The data was analyzed using one-way ANOVA and Tukey's post hock test at the significance level of 0.05 (P<0.05). Results: There were significant differences between the sham control and obese groups with respect to ZAG contents in plasma and adipose tissue, which was lower in obese groups (p<0.001). The eight-week high intensity interval training significantly increased the amount of secreted ZAG in adipose tissue compared to the control group (p<0.001). Conclusions: It seems that HIIT training increased ZAG content in the adipose tissue of the male obese rats. This can reduce the amount of adipose tissue through lipolysis of the adipose tissue.


Economic and social transferring period is a conflict-prone period, mismanage some conflict would cause public crisis. This study sum up the type and reason of the public crisis, put forward positive government communication can play an active role in dealing with public crisis.Through analyze the dissemination law of the information, the study consider that China government communication is restricted by conventional one-way publicity ideas, vertical bureaucratic structures, and bad information Sharing between intra-government. For that reason, in order to promote government communication capability, we should Reengineer old government Process; improve the mechanism of government crisis communication; construct E-government communication platform.


Air quality is an important factor for human health conditions. Simultaneously, suitable meteorology poses the circumstances for virus transmission. Hence, we investigated both these two important aspects for the COVID-19 pandemic. We correlated the remote sensing based observations of meteorological parameters and air quality parameters with COVID-19 cases from 657 districts all over the country and found that air quality parameters are playing very crucial role along with a few meteorological parameters for this outbreak. We observed that air temperature, and wind speed were significantly and positively correlated with COVID-19 cases but precipitation and humidity were negatively correlated with confirmed cases. Cloudiness had no significant relation in this aspect. Among the air pollutants, O3 was better correlating with COVID-19 cases. AOD representing the particulate matter concentration also significantly correlated with such cases majorly over Indo-Gangetic plain region. The carbon-pollutants CO was also very high over the same region. Though NO2 and SO2 were reduced during lockdown, due to the power generation and mining activities both these gases were quite highly correlated over eastern India region. We noted the eastern and western coastal districts of India and districts from the low-lying plain areas had more cases during this pandemic. Our study suggests that improving air quality with proper strict regulations and complete lockdown during the peak of pandemic could reduce the misfortune in all over India. Hence, the summer season could be susceptible and might pose a gesture of seasonality for this disease.


Abstract : The objective of the gear testing program was to provide growth potential for high capacity transmission systems, such as the CH-47A. Increased load carrying capacity for a gear system may be related to improvements in design, materials, or processing, or operating environment. This program undertook to compare three significantly different gear tooth grinding methods, and assess their effect on bending fatigue life. The three methods evaluated are as follows: (1) 'Maag' (Maag Gear-Wheel Co., Zurich, Switzerland); (2) 'Reishauer' (Fellows Gear Shaper Co., Springfield, Vermont); (3) 'Form' (Gear Grinding Division, Michigan Tool Co., Detroit, Mich.).

The effect of free-surface drift layers on the maximum height that a steady wave can attain without breaking is explored through experiments and numerical simulations. In the experiments, the waves are generated by towing a two-dimensional fully submerged hydrofoil at constant depth, speed and angle of attack. The drift layer is generated by towing a plastic sheet on the water surface ahead of the hydrofoil. It is found that the presence of this drift layer (free-surface wake) dramatically reduces the maximum non-breaking wave height and that this wave height correlates well with the surface drift velocity. In the simulations, the inviscid two-dimensional fully nonlinear Euler equations are solved numerically. Initially symmetric wave profiles are superimposed on a parallel drift layer whose mean flow characteristics match those in the experiments. It is found that for large enough initial wave amplitudes a bulge forms at the crest on the forward face of the wave and the vorticity fluctuations just under the surface in this region grow dramatically in time. This behaviour is taken as a criterion to indicate impending wave breaking. The maximum non-breaking wave elevations obtained in this way are in good agreement with the experimental findings.


To improve the level of teaching informatization in universities, this paper focuses on the construction and application of network-based SCT(smart classroom teaching) mode. First of all, we defined the concept of smart classroom and network teaching platform, and combined with the needs of online teaching. The basic architecture of intelligent teaching platform under SCT mode is established. Then, based on the software development process, applying object-oriented thinking and MVC framework, the dual-mode service platform of PC and mobile is designed. In the specific design, ASP.NET and MySQL database development technology are used to realize the client access between PC platform and Android, as the design of key modules. Finally, taking physical education teaching as an example, the platform is tested and analyzed. The results show that the program can meet the needs of physical education teaching process. In the experimental group, the overall recognition of SCT mode is high, and the degree of resource development and utilization is strengthened.


Data augmentation is one of the ways of dealing with labeled data scarcity and overfitting. Both these problems are crucial for modern deep learning algorithms which require massive amounts of data. The problem is better explored in the context of image analysis than for text. This work is a step forward to close this gap. We propose a method for augmenting textual data when training convolutional neural networks for sentence classification. The augumentation is based on the substitution of words using a thesaurus as well as the Princeton WordNet. Our method improves upon the baseline in almost all cases. In terms of accuracy the best of the variants is 1.2% (pp.) better  than the baseline.


China is one of the countries with the heaviest burden of hepatitis C virus (HCV) worldwide, especially subtype 1b. To better control hepatitis C, insights into the characteristics of dynamic spread and genomic mutations are urgently needed. We retrieved sequences of HCV‐1b NS5B among intravenous drug users (IDUs) and general people (Non‐IDUs) in China from 2000 to 2011 in NCBI. Bayesian phylogenetic and phylogeographic analyses were used to evaluate the transmission dynamics of HCV‐1b. Non‐synonymous substitutions were detected to illustrate immune adaptation. Evolutionary history demonstrated that HCV‐1b effective population size experienced a sharp increase in 1990. HCV‐1b sequences among IDUs had a higher estimated evolutionary rate (5.7185 × 10−3 substitutions/site/year) than overall (7.7332 × 10−4). 105/136 (77.2%) of HCV‐1b sequences clustered into 38 networks. The average non‐synonymous HCV‐1b immune epitopes among IDUs were 0.211, higher than non‐IDUs, especially in the HLA‐A*02 molecular recognition region. All of these posed significant challenges for the prevention and treatment of HCV. Heterogeneity and genetic linkages of HCV‐1b suggest that evolutionary surveillance of HCV in cities in east‐central China and among IDUs could not be neglected.


that infant mortality and absence of gerontocracy are indicated. Sex ratio favored males 125 to 100; except for mammoth hunters, groups were limited to ten to thirty persons. A. I. Hallowell maintained that the basis for culture existed in prehuman primates-and that from the beginning man has had the potential for creating changes in cultural systems. C. O. Sauer introduced the original and stimulating theory that fire-using and human society originated through women, and also postulated that early cultural development took place in tidal regions now under water. E. W. Caspari advanced the theory that populations which are relatively variable phenotypically are not necessarily more variable genetically than others less variable phenotypically, because differences in environmental pressure influence genetic expression; the Boasite nostrum that culture has replaced evolution is wrong. D. A. Hamburg argued that we utilize our remote ancestors' emergency system for readying muscles for action, not in immediate crises, but in emotional stress. When no action follows, cholesterol is dumped into our artery linings; mobilization without action equals atherosclerosis. Iago Galdston added that in the evolution of human society, glands have served as the humanizing organs more than the brain.


We propose a spin manipulation technique based entirely on electric fields applied to acceptor states in $p$-type semiconductors with spin-orbit coupling. While interesting in its own right, the technique can also be used to implement fault-resilient holonomic quantum computing. We explicitly compute adiabatic transformation matrix (holonomy) of the degenerate states and comment on the feasibility of the scheme as an experimental technique.


A therapeutic trial of a pan-T monoclonal antibody is described in a patient with a low grade mature T cell proliferation and haemopoietic suppression. The study shows that non-complement fixing IgG1 antibodies can be highly effective opsonins, and the dose required can be estimated from in vitro studies. It is demonstrated that therapeutic failure occurred due to the appearance of anti-mouse antibodies and not to antigenic modulation or reticuloendothelial blockade. The literature is reviewed and the potential role of serotherapy in malignant disorders is discussed.


Variability and trait association studies were investigated in 18 rice (Oryza sativa L.) genotypes with two replications in a RBD design during kharif, 2017 at Agricultural Research Station, Kunaram. The traits, plant height, number of productive tillers per m2 and number of grains per panicle showed high heritability coupled with high genetic advance values indicating these traits were predominantly governed by the additive genes. Grain yield had positively correlated with days to 50% flowering, plant height and number of grains per panicle, and negatively correlated with gall midge incidence at both genotypic and phenotypic levels suggesting that genotypes with longer duration, more plant height and good number of grains panicle with relatively very less silver shoots contribute for more grain yield.


The paper investigates the divergence between inflation and monetary expansion in Zimbabwe since late 2003. The substantial decline in velocity and increasing levels of real money balances during 2004 are at odds with a record of inflation closely tracking the growth rates of monetary aggregates in the past. Possible explanations for the divergence include an unstable demand for money, a sudden shift in the underlying demand for real balances due to a sharp change in an explanatory variable, and a structural break or aberration in a normally stable money demand relation reflecting some unexplained factor such as repressed inflation (given administered prices) or measurement errors in the consumer price index. The results of the study point to the last possibility as the most likely explanation.


Story in Brief Sixty-eight mature, pregnant Hereford Cows were used to determine blood constituents prior to calving when subjected to different prepartum nutritional regimes. Starting November 19, 1980, one group of cows was supplemented to maintain their November weight until calving. Three other groups were fed a low level of nutrition from November 19 to January 22, 1981; then the level of nutrition was increased for two of the three groups. One group was fed to return to their November weight by calving (low-high) and another group was fed to maintain their weight until calving (low-moderate). The third group was fed to continue to lose weight (low-low), so that approximately 10 percent ofthe November weight was lost by the time of calving. All animals were treated alike after calving. Projected weight losses were probably not achieved because of a mild winter, but losses were in the desired directions. Total esterified fatty acids in plasma were not affected by treatment. However, plasma glucose and protein were affected by treatment. When nutrition was increased, the concentration of glucose and protein in plasma were increased. Pregnancy rates ranged from 74 to 95 percent for the various treatments.

Human resources are back bone of any organization whether it religious or economic organization. TTD is premier religious and social welfare institution which administers Srivari Temple and 12 sub-temples. TTD has been emerged as one of the most dominant organization within the economy in respect of generating employment opportunities, and contributions it makes to the development and welfare of the society. HRD is a process of enhancing the capability of human beings to change their attitudes to produce the best results in an organization. A well formulated HRD practices yields better results and increases the reputation of the organization. The present study aimed at analyzing the HRD practices of TTD. It employs more than 9000 employees to manage religious and social welfare activities. A sample of 520 has been drawn to analyse HRD activities like training programmes, promotions, transfers and performance appraisal etc. 1. THE PRELUDE Tirumala Tirupati Devasthanams is an independent trust which manages the Tirumala Venkateswara Temple at Tiru- mala in Andhra Pradesh. The trust oversees the operations and finances of the richest and the most visited religious center in the world8 it is also involved in various social, reli- gious, literary health and educational activities within Andhra Pradesh and India. TTD employs more than 9000 employees to maintain the 12 temples and sub-shrines under its control along with the execution of its social activities. The activities of the TTD are not only confined to the propagation of Hindu religion but also launching various schemes and programmes for the social upliftment of the people in the country. TTD was established in 1932 as a result of the TTD Act of 1932. Administration of the temple was vested to a management committee of eleven members as appointed by the Andhra Pradesh Government. The provisions of A.P. Charitable & Hindu Religious Institutions & Endowments Act (1987) were followed for the administration of the TTD. It is indeed a vast organization with multifarious activities and huge resources. TTD has been emerged as one of the most dominant or- ganization within the economy in respect of generating em- ployment opportunities, and contributions it makes to the development and welfare of the society. Hence TTD is an important service provider both for the pilgrims and to the society, the quality of its service depends on the quality and satisfaction of the persons working in the organization and the quality of effort put in by them to achieve the organiza- tional goals. It is therefore obvious that in order to function more efficiently and effectively and to build up a loyal and committed workforce, the management should give atten- tion to the areas of HRD namely Training, Promotions, trans- fers and performance appraisal. The celebrated US scholar Leonard Nadler defined HRD "a series of organizational activities conducted within the speci- fied time and designed to produce behavioral change". Na- dler thus emphasized three things i.e. training, education and development. Training and development is a part of the Hu- man Resource Development Programme, which ensures that the organization has the people with the skill and knowledge to achieve strategic objectives. Training is an act of increas- ing knowledge and skill of an employee for doing a particular job whereas development means the employees acquire not only skill and competency in their present jobs but also ca- pacity for future managerial tasks.


We investigate the dilepton production in proton‐nucleus collisions at the forward rapidity region using the Color Glass Condensate approach. We focus our attention on the dilepton transverse momentum distribution (pT), more precisely in the low pT region where the saturation effects are expected to be increasingly large.


The author analyses the chain generating function for the self-avoiding walk problem on the honeycomb lattice. She uses the exact critical point value of Nienhuis and finds exponent values of gamma approximately 1.344 and Delta 1 approximately 0.93 for the dominant and first confluent exponents. The former value is in agreement with Nienhuis' exact result. Second and third confluent exponents, Delta 2 approximately 1.2 and Delta 3 approximately 1.5, are also identified, these exponents being consistent with Monte Carlo results and Nienhuis' exact irrelevant eigenvalue, respectively.


This paper addresses the thermal generator maintenance scheduling problem. The problem is formulated as a mixed-integer programming problem, and it is solved by using an optimization method known as simulated annealing. Since the simulated annealing method assumes an analogy between a physical multi-particle system and a combinatorial optimization problem, a global minimum can be found with high probability through a careful annealing process. Numerical results on real - scale test system have been obtained and the effectiveness of the proposed method has been demonstrated.


A warehouse system as a time transformation of the flows of goods plays an essential role in a complete logistics chain. The efficiency of a complete warehouse system largely depends on the efficiency of carrying out transport and handling operations. Therefore, it is essential to have adequate means of internal transport that will influence the efficiency of the warehouse system by its performance. In this paper, the evaluation and selection of side- loading forklift using the FUCOM-WASPAS model, which has been used for the first time in the literature in this paper, is performed. The FUCOM method was used to obtain the weight values of the criteria, while WASPAS was applied for the evaluation and ranking of forklifts. A possibility to apply the FUCOM method in group decision-making was presented. A comparative analysis, in which other methods of multi-criteria decision-making were applied, was carried out. The analysis showed the stability of the results obtained.


Special Economic Zones are economic areas that implement special policies within geographical confines.The growth of Special Economic Zones in our country can be divided into two stages: traditional Special Economic Zones and new Special Economic Zones.Currently,the former is facing challenges and the latter developing rapidly.As a regional economic development pattern,the Special Economic Zones actualize their impact on regional economic growth through polarization and diffusion effect.The polarization effect is mainly manifested as the accumulation of essential factors of production based on the market mechanism and special institutional arrangement.The diffusion effect works through the mechanisms of industrial gradient shift,institutional transplantation and imitation,and intellectual technology spillover.The Special Economic Zones should thus remain "special".On the one hand,the traditional Special Economic Zones should actively seek modifications,and on the other hand,we should promote the diversified growth pattern of Special Economic Zones according to the specificity of local conditions and retain policy-related variations between various Special Economic Zones.


GaAs Schottky barrier diodes continue to be heavily used in millimeter and submillimeter wavelength heterodyne receiver applications where cryogenic cooling is not an acceptable option. This is because the diode technology is well known, reliable, and yields acceptable sensitivities at room temperature. Planar GaAs mixer diodes can now replace the older whisker contacted diodes to at least 600 GHz, and THz devices are easily within grasp. This presentation will update the status of planar mixer diode technology at the University of Virginia. Recent developments include methods to reduce anode dimensions and parasitic shunt capacitance, fabrication of GaAs diodes on quartz substrates with integrated circuit elements, and fabrication of a diode pair with an integrated log-periodic antenna and separate diode biasing for subharmonic mixing. The paper will conclude with a summary of the status of mixer performance based on planar diodes and a discussion of the potential for THz mixers.


From the perspective of urbanization and labor transferring,the continued rising up of food price and housing price is a natural phenomenon at the structural stage of urbanization and industrialization,it is related with the gap between rich and poor.Depend on fiscal policy and industrial policy,it is possible to impact the distribution of wealth and industrial distribution of capital and labor,giving full play to the structural adjustment credit policy,so the prices can be effectively controlled.


This study aimed to evaluate the effect of the photoperiod on the fillet composition of Nile tilapia juveniles. We employed a completely randomized design with five treatments (0L:24D, 6L:18D, 12L:12D, 18L:6D, 24L:0D) and four replications. We used 160 Nile tilapia juveniles, distributed in 20 tanks containing 20 liters of water, in a recirculation systems, at controlled temperature of 27 °C and density of eight fish per tank. Fish were fed twice a day with commercial extruded feed containing 40% crude protein. Samples of the fillet at the end of 75 days were collected and stored in a freezer at -80 °C for subsequent analysis of chemical composition. There was no effect of photoperiod on moisture and ash content of the fillet (P>0.05). The period 18L:6D showed higher amounts of protein in the fillet, as well as lower amounts of fat (P<0.05). Therefore, it can be concluded that the photoperiod can alter Nile tilapia body composition, and the photoperiod 18L:6D contributed to the higher concentration of crude protein and lower fat deposition in Nile tilapia fillets. KEYWORDS: composition, nutrient retention, Oreochromis niloticus.

The evaluation of government programs in order to reduce poverty and reach equal distribution of income is considered to be running quite slowly. This is indicated by the percentage of poor people that only decreased less than 1% a year since 2010; even the percentage of poor people increased in September 2015. Therefore, funding or material assitance is needed from other sources that can be used as a driver of poverty alleviation such as zakat, infaq and waqf, which are adopted from the Islamic Economics system. This study examines the implementation of Islamic Economics in order to improve prosperity in Indonesia, especially the poor. The implementation of zakat is mandatory for certain groups and the distribution should be based on certain characteristics including those who need help. Infaq and waqf are more general and can be applied to wider population. By optimizing the acceptance of zakat, infaq, and waqf, revenues will be distributed from high income populations to low-income populations so it can improve the


SMALL CELL LUNG CANCER (SCLC) accounts for 20% of all lung cancers. Although SCLC is characterized by rapid tumor doubling time and early metastasis, chemotherapy protocols are very successful in most of the patients. Response rate to combination chemotherapy is high, up to 75–80% in extensive disease and up to 85–95% in limited disease.1,2 Nevertheless, most patients die due to disease Tc-99m MIBI SPECT in prediction of prognosis in patients with small cell lung cancer


Tooth movement in orthodontic therapy is achieved by application of forces and moments to individual teeth. For lack of properly sized force/moment transducers (FMTs), the measurement of the applied force and moment vectors has remained a challenge. This paper reports on two six-degree-of-freedom FMTs termed Designs A and B, which were developed for this purpose. Their measurement principle makes use of the fact that external loads acting on them cause mechanical stress distributions, which are mapped using piezoresistive microsensors integrated in CMOS sensor chips. In Design A, two metal pins sandwich a single sensor chip, whereas in the newer Design B two CMOS chips are mounted in a back-to-back configuration between two pins. With a diameter of 4.5 mm and length of 16.4 mm, Design B is slightly larger than Design A, but still comparable with a tooth root. The two designs were calibrated and tested by applying forces and moments in the clinically relevant ranges of ±3 N and ±30 Nmm. The design changes from Designs A to B improve the smallest singular value of the sensitivity matrix by a factor of 10. The resolution achieved by Design B is 21 mN, 39 mN, and 100 mN for the three force components and <inline-formula> <tex-math notation="LaTeX">${24\times {10^{-3}}}{~\text {Nmm}}$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">${33\times {10^{-3}}}{~\text {Nmm}}$ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">${4\times {10^{-3}}}{~\text {Nmm}}$ </tex-math></inline-formula> for the three moment components. In comparison with Design A, these values represent improvements by factors of 2.3 to 4.5.


At the fortieth anniversary of reform and opening-up, the socialist market economy reform has entered a deep-water area. With the rapid development of economy and society, the demand for material and cultural resources has been expanding, coupled with the explosive growth of information brought by the rapid development of the Internet, complex social life has brought psychological and material impacts on young people who are far from mature. Under the new situation, juvenile delinquency has entered an unprecedented stage. The total number of juvenile delinquency has been rising, and the proportion of juvenile delinquency in the total number of criminal of fences in China has remained high, which has attracted wide attention from all walks of life. Therefore, this paper chooses domestic juvenile delinquency as the research object under the new situation. Juvenile delinquency, defined from the perspective of criminology, refers to the criminal acts committed by people aged 14-25, including illegal acts against social security and bad acts against moral norms. This definition expands the scope of criminal acts to illegal acts and bad acts, where bad acts refer to immoral acts or acts that may lead to crime. Therefore, it is pointed out that juvenile delinquency refers to social harmful acts committed by people aged 14-25. Generally speaking, juvenile delinquency includes a wider range of acts. From the perspective of professional research, the juvenile delinquency we refer to generally refers to criminal acts involving criminal law. 1. Characteristics of Juvenile Cybercafe The so-called caber crime refers to the serious harm to society and even violation of specific criminal law committed by criminals on the network by exploiting the loopholes in their programming, encryption, decoding technology or tools, software instructions, product encryption technology and legal provisions, or by taking advantage of their special status as a network provider or other means. Like other social crimes, juvenile cybercafe has the basic characteristics of social harmfulness, illegal behavior and punishment by criminal law. However, as a new social crime phenomenon, especially in the high-tech field committed by the special group of juveniles, it has its own characteristics. Most of the teenagers who commit cybercafe have high educational background, can operate computer skillfully, and have strong skills in computer technology. Juvenile caber crime is a caber-induced crime. The good and meaningful information on the Internet 2019 International Conference on Arts, Management, Education and Innovation (ICAMEI 2019) Published by CSP © 2019 the Authors 756 has a negative impact on the values and outlook on life of teenagers, which is the basic cause of counterinsurgency. Counterinsurgency has very high concealment. The otherworldly is a virtual space. The methods of cybercafe are mostly implemented through the operation of procedures and data. The invisibility of cybercafe makes it difficult to detect. Counterinsurgency has the character of "beyond time and space". The time required for the implementation of cybercafe is very short, which brings great difficulties to the investigation and evidence collection. On the other hand, the location of the crime is uncertain, which also makes the case detection impossible. Counterinsurgency is harmful to society and causes serious economic losses. Early hackers mostly destroyed other people's secret system to show their superb technology. Today, the goal of juvenile cybercafe is directly directed at computer information system which is related to national economy, people's livelihood and national security. Electronic money contains the great risk of triggering financial crisis, which is often attacked by hackers nowadays. 2. Current situation of juvenile Cybercafe In recent years, the popularity of the Internet has increased rapidly, but the cases of juvenile cybercafe are also on the rise. According to the survey in Jungian, Shanghai and Shijiazhuang provinces, the proportion of juvenile cybercafe is increasing, which has a serious impact on society and economy. There are many kinds of juvenile cybercafe. It can be said that besides homicide and other crimes that directly infringe on the person, almost all other crimes can be carried out on the network, such as electronic theft, online fraud, online intimidation and so on. According to the information reported publicly by relevant departments, cybercafe in China is increasing year by year, while the age limit is declining, mostly for teenagers aged 16 to 17. Although the current juvenile cybercafe in China is not as prominent as that in the West, it is expected that in the next few years, such crimes will become one of the most harmful crimes in society. As shown in figure 1: Figure 1. Performance of juvenile delinquency 3. Measures to Reduce Juvenile Delinquency Under the current new situation, the countermeasures to reduce juvenile delinquency should include two aspects: prevention beforehand and treatment afterwards, prevention includes prevention beforehand and prevention of recidivism, and governance includes two aspects: prison


The mass manufacturing of composite products is hindered by long curing times, and composite manufacturers demand shorter curing cycles while keeping material properties. This requires reliable methods to predict the curing kinetics of each resin formulation. Isoconversional methods are easy to implement and able to deal with complex processes. However, scientists still limit their isoconversional predictions of curing degree to isothermal or constant heating programs. In this study, we perform combined dynamic and isothermal DSC measurements for two different commercial epoxies for aerospace applications (M18 and VTC401). Based on the isoconversional kinetic analysis, we show the feasibility of predicting the evolution of an epoxy resin cure for an arbitrary and complex temperature program using two different unexplored methods for this purpose. Because of the versatility of both prediction methods, they are especially suited to deal with actual conditions in industrial processes. The proposed approach is validated experimentally by comparing predictions against the curing degree of these epoxies during a temperature program that comprises isothermal and dynamic stages. These reliable and straightforward predictions open the door to optimize curing times and increase productivity in composites.


Investors in firms with concentrated supplier or customer bases should not assume that idiosyncratic shocks to an economically linked firm disappear in a well-diversified portfolio. Customer-supplier linkages between firms are a channel by which shocks to a single firm can influence the stock returns of other, linked firms. When the distribution of connectivity in a firm's economic network is fat-tailed, individual firm-level shocks do not average out in aggregate. Consequently, firms with concentrated supplier or customer bases have higher average returns than firms with more diversified supplier or customer exposures.


The inclusion of people with disabilities in society is an issue that is currently becoming relevant. This is why technology is in a constant struggle to develop tools that meet the needs of this sector of the population and with it fulfill this objective. One of these disabilities is blindness. Therefore, this chapter shows an analysis of the application of virtual reality (VR) and haptic devices as support tools in the teaching-learning of people with such disabilities through the study of various projects that have implement these technologies, obtaining the advantages and disadvantages offered by these resources. For this, an analysis is made from the point of view of accessibility that it presents as well as the approach of the user-centered design (UCD).

During certain meteorological events, water level oscillations up to 1.5 m with periods of less tha n 2 h have been observed in the Great Lakes. The squall line events of 7-11 March 1998, 29 May-2 June 1998, and 8 -12 November 1998 in Lake Michigan, are analyzed by spectral and analytical methods. Dominant periods of less than 2 h are identified in the spectra of water level fluctuations and coherencies among the spectral peaks of water levels of different station pairs are calculated to determine whether the oscillations are localized or basin wide. Explicit numerical calculations of normal mode periods and structures using a Lanczos procedure show that the dominant periods in the observed data are consistent with the structures and periods of some of the calculated modes. The March 1998 and the November 1998 episodes show higher surges with a gradual rise of water level, while the episode of May 1998 shows an abrupt rise in the water level at Calumet Harbor and about ten times higher spectral signature than the former two. Many of the high-frequency modes have large amplitude at or near Calumet Harbor and the periods are close to the periods of edge waves that would be generated by a squall line similar to the May 1998 squall line. The trapping of energy and localized higher modes in a water body can work together to excite edge waves and localized seiches causing abrupt water level fluctuations.


Two new species of the Drosophila ananassae subgroup are described. D. comorensis Tsacas sp. n. and D. merina Tsacas sp. n. are endemic to the Indian Ocean islands Comores and Madagascar, respectively. Comparisons with 2 other species, also endemic to Indian Ocean islands and belonging to the D. ananassae subgroup, D. ercepeae Tsacas & David from La RA©union and D. vallismaia Tsacas from Seychelles, lead to the definition of a 3rd complex, ercepeae , within this subgroup. Relationships among the 4 species of the ercepeae complex are based on morphological data (the only data available for D. comorensis ), mitotic and polytene chromosome analyses, behavioral interactions, interspecific hybridizations, chemical analyses of cuticular hydrocarbons, and amylase polymorphism. Within this complex, D. ercepeae and D. merina are distinguished from D. vallismaia and D. comorensis . All characters show close affinities between D. ercepeae and D. merina . The geographic distribution of the species of the 3 complexes of the D. ananassae subgroup is also discussed.


Differential thermal analysis, X-ray powder diffraction, and tensimetry are used to study the rhenium-oxygen system in the Re-Re 2 O 7 composition region. Re 2 O 7 , cubic ReO 3 , and orthorhombic ReO 2 are the equilibrium oxide phases in this system. Re 2 O 5 is not a stable phase in the system. We suggest that monoclinic ReO 2 + is a metastable phase and that a homogeneity region exists in orthorhombic ReO 2 . p-T and T-x diagrams (without the vapor line) are built for the rhenium-oxygen system. The specificity of the system consists of a strong displacement of the eutectic point in the T-x diagram toward the low-melting component (Re 2 O 7 ). Line {Re 2 O 7 ( S ) , ReO 3 ( S ) , V} in the p-T diagram, in fact, coincides with line {Re 2 O 7 ( s ) , Re 2 O 7 ( v ) } for individual Re 2 O 7 , and line {ReO 3 ( S ) , L, V} coincides with line {R 2 O 7 ( L ) , Re 2 O 7 ( V ) } for individual Re 2 O 7 .


Germination of Phacelia tanacetifolia Benth. (cv. Bleu Clair) seeds is accompanied in its early phases by the development of the K+ uptake capacity. Dormancy due to light and high temperatures and the negative effect on seed germination of a medium with low water potential inhibit the development of potassium uptake. Fusicoccin, which promotes seed germination under all examined conditions, accelerates also the appearance of the K+ uptake capacity. The relationship between the development of K+ uptake and seed germination in Phacelia tanacetifolia is discussed.


How to estimate soil moisture beneath vegetation using SAR data is an important study topic for SAR applications. The Polarimetric SAR Interferometry (PolinSAR) has a very promising application for solving this key problem. At this paper, based on spaceborne SIR-C L band PolinSAR data, a new sub-canopy soil moisture estimation method for ground-forest terrain is proposed. Firstly, from PolinSAR random Volume+Ground two layer coherent scattering model, using full maximum likelihood inversion method, the ground polarimetric covariance matrices of ground-forest terrain is reconstructed; Secondly, from ground backscatter polarimetric matrices, the Freeman Alpha is obtained; Thirdly, using surface and dihedral scattering model, the soil dielectric constants is estimated from Freeman Alpha; finally, sub-canopy soil moisture is obtained from Dobsen Model. The preliminary result indicates that the reasonable and promising result has been obtained, the future work will focus on method refine and further result validation using new data and ground truth.

When he wrote these words in 1900, Mark Twain conceived of the Dreyfus Affair not so much as an act of antisemitism, but as the moral failure of French culture and society at the expense of an individual who happened to be Jewish. This description of the Affair runs contrary to its once-predominant image in Jewish and European historiography. Until recently, historians presented this episode by distinguishing between proponents and opponents of assimilation within European Jewry. In describing Jewish responses to the Affair, they contrasted the passive assimilationism of French Jewish leaders to the quintessential antiassimilationist response articulated by Theodore Herzl and Max

The obstetrics and gynecologic anamnesis, presence extragenital pathologies, features of a current of pregnancy and sorts, age, presence of bad habits has been analysed. On the basis of the analysis risk factors have been revealed and the scale is made prognostic.


This paper investigates the distributed quantized <inline-formula> <tex-math notation="LaTeX">$H_{\infty}$</tex-math></inline-formula> consensus problems for general linear and Lipschitz nonlinear multiagent systems with input quantization mismatch and external disturbances under switching weighted undirected or balanced directed topologies. The designed distributed quantized <inline-formula> <tex-math notation="LaTeX">$H_{\infty}$</tex-math></inline-formula> consensus protocol can be divided into two parts which are linear and nonlinear parts. The linear part plays a role in achieving satisfactory performance against interval-bounded model uncertainties, external disturbances, and unknown initial states. The nonlinear part eliminates the effect of input quantization. It should be mentioned that complete consensus instead of practical consensus can be achieved in the presence of uniform quantization. In addition, instead of requiring the coupling strength among neighboring agents to be larger than a threshold value as in previous literature, the coupling strength in this paper can be determined by solving some linear matrix inequalities. Sufficient conditions for the existence of the proposed control strategy are also obtained by using the LMI technique. Finally, two numerical examples are presented to show the effectiveness and advantages of the proposed consensus strategy.


A new numerical algorithm is presented for the solution to the point kinetics equations (PKEs), whose accurate solution has been sought for over 60 years. The method couples the simplest of finite difference methods, a backward Euler, with Richardsons extrapolation, also called an acceleration. From this coupling, a series of benchmarks have emerged. These include cases from the literature as well as several new ones. The novelty of this presentation lies in the breadth of reactivity insertions considered, covering both prescribed and feedback reactivities, and the extreme 8- to 9- digit accuracy achievable. The benchmarks presented are to provide guidance to those who wish to develop further numerical improvements. (authors)


Two polymorphic structures of hydrazonium monobasic salts of 3,5-pyrazolcdicarboxylic acid are described. In both instances, one-dimensional infinite chains formed by acid molecules through O-H···O hydrogen bonding (1.68 A, 177.1°;1.71 A 169°) are inter-linked by hydrazonium dications to form two-dimensional sheets. The subtle structural difference between the two forms arises in the packing of hydrazonium dications. In form A, the hydrazonium dications are relatively close packed compared to those in form B. The closest N.....N distance between two hydrazonium dications of inversion related layers in form A is 2.03 A whereas the closest N.....N distance between two similar hydrazonium dications (disordered) is 4.89 A for form B. This account for the higher packing fraction (78% vs 76.2%) of form A compared to form B.


We describe the formal specification and automated synthesis of a strategic airlift scheduler for the Air Mobility Command of the US Air Force. The program synthesis system, the Kestrel Interactive Development System, composes a formal domain theory with a formal description of a class of algorithms (global search with constraint propagation) to produce provably correct and highly efficient code that outperforms more conventional approaches to this scheduling problem.


The loss of label from three microsomal subfractions of Morris hepatomas 7800 and 9618A following i.v. administration of leucine-1-14C was found to be decreased, compared with that of normal liver. However, the rate of degradation of membrane protein in the 7800 hepatoma was more rapid than that in its host liver, while the proteins of the reticular membranes of the Morris 9618A hepatoma decayed at a slower rate than did those of its host liver. Despite the varied decay rates, the yields of microsomal membrane protein from the hepatomas were diminished in all instances, compared with those of normal liver. No differences in the t 1/2 values were observed among the respective subfractions of a given liver or tumor, when compared with one another. The half-lives of the microsomal fractions of host and normal lives were approximately 35 and 20 hr, respectively. Half-lives of the sodium dodecyl sulfate-solubilized microsomal proteins, as fractionated by polyacrylamide electrophoresis, varied inversely with molecular weight in the host liver, whereas the same protein fractions in the hepatomas did not vary with molecular size and showed extended t 1/2 values. Most t 1/2 values obtained for the electrophoretically separated proteins were in the same range as the overall decay rate exhibited by the fraction. While these results suggest random defect(s) in the control of degradation of membrane proteins of the hepatoma, the data also support the concept that degradation of individual membrane proteins is largely dissociated from the degradation of the total particulate membrane.

INTRODUCTION Book reading is only one of the many types of reading so important in the lives of societies today. For this reason, the questions asked in this survey pertained not only to books in either paper or electronic form but also the press, Internet content and a general text of several pages in any form. This methodology allowed Izabela Koryś to draw a multidimensional picture of readership in Poland (as described in the first part of this report). Koryś disassembled the declared reader and buyer behaviour into a broader array of information about the public's contact with text. This broader approach does not imply, however, that books have ceased to be the area of special interest to the Book and Readership Institute of the National Library. The fundamental task of this multi-year study has always been to describe in-depth the phenomena and processes that are decisive for the social role of books in modern Poland. This part of the report is dedicated fully to analysing respondents' declarations concerning their contact with books. The information provided in the first part of this report – namely, how many Poles define themselves as book readers and buyers and how much different social groups are interested in books – will be supported in this part with more detailed data on the types, subjects, specific authors and titles of books that the respondents indicated as their choices for reading and/or buying. This knowledge provides a foundation for identifying certain functions (cognitive, emotional, social) performed by books, which are a unique medium, and defining the attributes of their content. The 2010 book reading and buying data are supplemented with a historical background in the first part of this report.1 A brief historical summary seems appropriate


The rising development of pollution has been extensive to the marine environment, although it has been one of natural places more stable for years, it is polluted marine aquaculture worldwide at present is being severely affected. It will be linked interrelationships between human health and the oceans. The opportunistic pathogen is Staphylococci 21 strains isolated from parangipettai coastal waters. Further Identification of S.aureus was confirmed as Biochemical tests and PCR by using universal primers 27F and1492R. These strains were analyzed for the detection of α, β and δ hemolysin on sheep, bovine and horse blood used hemolytic activity. Out of 21 strains there is only one strain can detect β-hemolytic activity and hemolysins producing strain were confirmed S.aureus.


This short story series is a coming-of-age and dystopian series that focuses on the impacts of the fear of imagination and discrimination on preteens and how they cope with it. This fear is shown through a virus named imaginatio virus, a special virus that attacks the main characters to induce imagination. The government made imagination-prevention and discrimination rules to get rid of the virus completely. We explore how the fear of imagination and discrimination affect the four main characters in each story. We apply the theory of social influence, discrimination, and coping mechanisms to show how Dylan, Elias, Bryna, and Corina deal with the effects of discrimination. In our creative work, we show that the four main characters succeed in being confident by focusing on the strength in themselves, finding help in trusted people, and not dwelling in the problem. Keywords: imagination, short stories, discrimination, dystopian, coming-of-age

Evaluation of the quality of complementary flour and its nutritional adequacy in relation to infant's nutritional requirements was done to four different types of complementary flour (composite cereals with groundnuts, maize, millet and sorghum). The collected samples were analysed for determination of macronutrient, micronutrients and phytate content. The mean protein content in all types of complementary flour was 7.30 ± 2.52 g/100 g. A significant difference in protein content between composite cereals ( p ≤ 0.001) and other types of cereals-based foods was observed. Fat and iron content were found to be inadequate in all types of complementary flours. Phytate content ranged from 59.47 - 1176.8 mg/100 g, the highest content was observed in sorghum. On the other hand, the mean iron and zinc content in all types of complementary flour was 5.25 ± 1.35 mg/100 g and 2.99 ± 1.36 mg/100 g respectively. The molar ratios of phytate:iron and phytate:zinc were at a level that would tend to inhibit bioavailability of iron and zinc in 97% and 45% of analysed samples respectively. An association between anaemia and phytate:iron molar ratio (AOR = 4.2, 95%, 1.2 - 6.9) was observed. The quality and adequacy of nutrients in cereal-based complementary flour has shown to be inadequate and likely to be compromised by the presence of phytate.


This study provides an examination of two Japanese sporting goods corporations, Asics and Mizuno, to uncover the ways in which the traditional forms of Japanese management have been modified to fit within a post-industrial, global context. Our findings reveal a strong link between the cultural context of the firms and their managerial approach. However, the impact of traditional Japanese values is tempered by the existence of both firms in a global industry that have led to western values and practices becoming increasingly influential. This hybrid approach is contrasted with the explicitly marketing-oriented stance of western firms in the industry, most notably exemplified by industry leader Nike.

For External Quality Assessment all blood banks do not satisfying the need 0% (0/13). ......................


Sir: I read with interest the brief report by Eyden & Banerjee' on this topic. The authors maintain that this is the first account of this phenotype in multiple myeloma. I should like to draw their attention to the report by Chen et al. in 1985*. These authors reported a case in which the neoplastic cells had vacuolated cytoplasm histologically simulating signet-ring cell lymphoma. They described both light microscopic and ultrastructura1 features of the case which they termed 'clear cell myeloma'. It is clear that their observations preceded those of Eyden & Banerjee. Additionally, the latter report makes only brief mention of signet-ring cell lymphoma, citing one report by Cross et al. of a T-cell lymphoma3. By far the majority of lymphomas with signet-ring cells have proven to be of Bcell type, as reported initially by Kim et aL4. The paper by Chen et al. provides an additional eight references to signet-ring cell lymphoma^^-'^. Subsequently, Weiss et al. described histological, ultrastructural and immunohistochemical studies on two cases of T-cell signet-ring cell lyrnph~ma'~. In our initial report of 19784, we described microvesicles in the vacuoles of the B-cell signet-ring cell lymphoma and assumed that these structures represented immunoglobulin. To our surprise our ultrastructural studies on the subsequent T-cell signet-ring cell lymphoma' disclosed similar microvesicles. I note that Eyden & Banerjee have also described and have illustrated microvesicles within the vacuoles of signet-ring cell myeloma. Thus, the nature of these structures remains enigmatic.


The LaCosteRomberg airborne gravimeter is the key subsystem of the Chinese airborne gravimetry system.It is basically the combination of high precise vertical accelerometer that measuring acceleration and stable platform that to keep sensing system aligned in the correct vertical position.When employed in flight survey,the stable platform couldn't keep exactly level and may be tilt due to the existence of the horizontal acceleration of the aircraft.As a result,the meter orientation is incorrect,resulting in an off-level error,which we called the horizontal acceleration correction.It is obvious that the precise determination of the horizontal acceleration correction is one of the very important aspects to improve the accuracy of the airborne gravity.Generally,this correction can be formulated in two different forms,namely a form of two steps and that of one step.We have proved that the two forms are equivalent if the tilts of the stable platform are small.To reduce the potentially systemic biases due to the imperfection of the horizontal acceleration correction,a method involved pre-filtering of the raw data before the tilt correction is advanced.The pre-filtering amount that matches the platform period is suggested to be used which as a result of the spectrum analysis of the tilts.Finally,the validity of the proposed amount is verified and analyzed using actual airborne gravity data.The results indicate that the systemic biases of the airborne gravity anomaly compared to ground reference can be reduced from 5×10-5m ·s-2 to 0.5×10-5m ·s-2 by using of the proposed pre-filtering amount.
