ABSTRACT In recent years, the British polling industry has encountered difficulties in its attempts to measure voting intentions in important popular consultations, notably the 2014 referendum on Scottish independence, the 2015 UK general election, and the 2016 EU membership referendum. In such a context, it is extremely valuable to explore how different forecasting models that rely on political and economic variables can be used to predict the outcome of elections. In this paper, we propose such a model by introducing a political economy equation to estimate the vote share obtained by the incumbent party in UK general elections three months before the vote as well as a set of seemingly unrelated regressions (SUR) to forecast the results of the Official Opposition, the Liberal Democrats, and the remaining parties.


Topicality. Military threats determined the significant pace of changes in the risks of mixed cargoes transportation and proved the need for new methods of ensuring the reliability of transportation. First of all, there was the problem of assessing the levels of transportation reliability along individual routes and modeling a possible change of routes with the choice of safer options and ways of transportation. A particularly important function of such a model, due to the rapid pace of changes in risks, is the possibility of its practical application in real-time conditions.Aim and tasks. The purpose of the work is to develop a mathematical model of mixed cargo transportation in the conditions of dynamic changes in risks to increase the reliability of the transportation process, analyze alternative options for transportation, and identify opportunities for changing the route even in the process of cargo transportation. Achieving the goal of the study made it necessary to set and solve the following tasks: to implement the possibility of analyzing alternative transportation options and proposing route changes in real time; prove the capabilities of the developed model on the example of specific enterprises; to ensure reliability forecasting of the next cargo transportation stages; implement the possibility of optimizing multi-purpose tasks to ensure reliability, minimize the cost and time of transportation; to stratify the reliability of cargo transportation according to the level of threats probability.
Materials and methods. Various general and special methods of knowledge were used in the work: the method of quantitative and qualitative comparison for the stratification of the cargo transportation reliability depending on the risks at individual stages; methods of vector analysis to take into account the probability of the cargo transportation risk at each stage of mixed transportation; the method of induction and deduction made it possible to consider the reliability of the transportation as the reciprocal of the transportation risk probability; the task fragmentation method allows to include probable stages of transportation in different transport routes; a method of mathematical formalization of the problem for the formation of a model of mixed cargo transportation using water transport in conditions of dynamic changes in risks.
Research results. A mathematical model of mixed cargo transportation in conditions of dynamic changes in risks was developed to increase the reliability of transportation, analyze alternative transportation options, and identify opportunities for changing the route during cargo transportation. To solve this, the following tasks were developed: a mathematical model capable of analyzing alternative transportation options and proposing route changes in real life was developed; proven possibilities of the model on the example of specific enterprises; forecasting of the reliability the next cargo transportation stages is ensured; the possibility of optimizing multi-purpose tasks to ensure reliability, minimizing the cost and time of transportation has been implemented; stratification of the reliability cargo transportation by the level of probability threats was carried out.
Conclusion. Using the model, the activities of enterprises that transported their products through the ports of the Sea of Azov were analyzed. Due to the decrease in the reliability of cargo transportation through the Kerch Strait, alternative routes for the transportation of mixed cargo are proposed, for the use of "river-sea" vessels at certain stages. Approbation of the model for increasing the efficiency of the transport and logistics process of enterprises proved its effectiveness. The use of the developed mathematical model for the analysis of enterprise activity indicated an implicit advantage of increasing the level of transportation reliability, in particular, in relation to identifying the possibility of reducing warehouse stocks with a significant saving of working capital at the same time. The presented results of the research make it possible to ensure the proper reliability of transportation of mixed cargoes, even in conditions of significant dynamic changes in the level of threats on transportation routes.

In silico approach has been carried out for the determination of drug candidates from anthocyanin derivative as inhibitors of the COVID-19 main protease. Geometry optimization has performed using the DFT/B3LYP/6-31G(d,p) method as an initial step to prepare candidate ligand. The results of molecular docking showed that candidates C5 and C6 had promising results with a grid score smaller than the ligand reference (X77) with a flexible conformation type. Studies on absorption, distribution, metabolism, excretion, and toxicity of C5 and C6 candidates were conducted to study the physicochemical properties of drug candidates and to show good predictive results as drugs. Molecular dynamic simulation uses the ffSB14 force field for 200 ns to study the interaction between ligand and receptor, the system stability, solvent accessibility, energy interactions, and hydrogen bonds. The results show good interaction stability on the C5 complex compared to the reference ligand which is characterized by the binding free energy value of C5 was -42.77 ± 0.37 kcal/mol and X77 was -42.37 ± 0.41 kcal/mol.

Dr. Settanni's fascinating study of John Stuart Mill's outlook on religion probes certain fundamental tensions and contradictions in his thinking. What is described herein is the history of one thinker who could not fully embrace the theism of orthodox religions and yet who could never be content with skepticism either. His education in philosophic Utilitarianism led him toward agnosticism. His wife's death led him toward belief. These same tensions are present, although in an admittedly more abstract manner, in his philosophy. The text reveals how Mill attempted to resolve these contradictions by a probabilist form of Theism, and the question remains as to how ultimately successful he was.


The engineering manual provides a complete companion documentation about the structure of the main program and subroutines, the preparation of input data, the interpretation of output results, access and use of the program, and the detailed description of all the analytic, logical expressions and flow charts used in computations and program structure. A numerical example is provided and solved completely to show the sequence of computations followed. The program is carefully structured to reduce both user's time and costs without sacrificing accuracy. The user would expect a cost of CPU time of approximately $5.00 per building zone excluding printing costs. The accuracy, on the other hand, measured by deviation of simulated consumption from watt-hour meter readings, was found by many simulation tests not to exceed + or - 10 percent margin.


Phloroglucinol is a powerful antioxidant compound and an active pharmaceutical ingredient used in the management of intestinal spasms. In this report, we describe the interaction of γ-cyclodextrin with phloroglucinol to readily form a solid inclusion compound with 1:1 by co-dissolution and freeze-drying. Solid-state characterisation using FT-IR, thermal analyses (TGA and DTA) and X-ray powder diffraction confirmed the formation of a true inclusion compound (γ-CD·PG) in which the molecules of γ-CD are stacked into channels. This spatial arrangement is typical of γ-CD inclusion compounds, and it allows for the guest molecules to be located inside these channels. The evaluation of the antiradical potential of γ-CD·PG (against O2•⁻ and NO•) on different steps of the digestive process (mouth, gastric and intestinal phases) led us to conclude that the inclusion of phloroglucinol promoted better antioxidant activity at the end of the digestion when compared to the free phloroglucinol


ISSN 1948-6596 news and update commentary The geographic consequences of climate change for migratory birds Modern global climate change can affect species in natural communities in a variety of ways. One outcome that has received broad attention within the biogeographical community is species' range shifts. There is growing empirical evidence for shifts that, in the majority of cases, follow climate change expectations with species moving to higher latitudes or to higher elevations (Parmesan 2006). With the growing appreciation that species are indeed responding to climate change, there has been an expanding modeling effort to project the long-term geographical consequences. Specifi- cally, workers have developed models that use species' climatic niches (or envelopes) within their current geographic range to forecast species' dis- tributions under future climate-change scenarios (Pearson & Dawson 2003). When birds are considered in these investi- gations, shifts in breeding ranges in northern tem- perate-regions are often examined with little at- tention given to winter ranges in equatorial re- gions or the consequences of range shifts for mi- gratory routes and strategies. In many cases, this is due to simple data limitations: the most thor- ough occurrence information for birds is typically confined to breeding and non-breeding ranges in Europe and North America. Migration under cli- mate change has been an important topic of in- vestigation (Parmesan 2007); however, most analyses address questions related to phenology where data tends to be more prevalent. In a re- cent article in the Journal of Biogeography (Doswald et al. 2009), Nathalie Doswald and col- leagues applied climate envelope models to both the breeding and non-breeding ranges of 17 Euro- pean Sylvia warblers, a group of birds that are common residents and visitors to Europe. Doswald et al. (2009) extends the findings of ear- lier investigations (e.g., Huntley et al. 2006) by quantifying the geographical consequences of cli- mate change for migratory species, thus expand- ing the predictive breadth of recent modeling en- deavors and also our appreciation of the many challenges birds and other taxa will likely face un- der climate change. Migration is a common strategy for birds. To have enough energy to undertake long jour- neys, birds must build large quantities of fat re- serves. If climate change results in greater migra- tion distances, the viability of this phenomenon could be seriously challenged. Doswald et al. (2009) found that the majority of breeding ranges for the 17 Sylvia species were projected to shift northwards, but there was no evidence for a con- sistent directional shift with winter ranges. Thus, potential changes in migratory distances were, in most cases, a consequence of shifts in breeding ranges rather than winter ranges. Assuming spe- cies retain both breeding and non-breeding ranges and all individuals migrate in a similar fash- ion, migration distances were estimated to in- crease by an average of 413 km for trans-Saharan migrants and 201 km for resident and short- distance or partial migrants. Assuming increases in fuel requirements for longer migrations can be physiologically accommodated, these species are likely to require more time for feeding or richer food resources prior and during migration to achieve these longer distances. Alternatively, mi- gration behavior might diminish to the point where separate breeding and non-breeding ranges are no longer a necessity, particular for short-distance or partial migrants whose breeding and non-breeding ranges are located at higher latitudes. An additional pattern examined by Doswald et al. (2009) was the degree of range overlap be- tween the current and projected breeding and non-breeding ranges. These values were found to be highly variable among species with an overlap of 33% and 36% on average for breeding and non- breeding ranges, respectively. Regions of overlap can be seen as important transition zones, allow- ing populations to persist within their historical ranges, thus providing valuable time for species to respond to changing climatic conditions.

The conformational properties of 1,3-dithia-5,6-benzocycloheptene (7) (2,4-benzodithiepin), three 2,2-dialkyl derivatives, and two monosubstituted derivatives (2-CH3 and 2-OCH3) have been investigated by 1H and 13C dnmr methods. It is reported that the most stable conformation of the seven-membered ring is a chair on which, in the case of the monosubstituted compounds, the 2-CH3 group adopts an equatorial position while the 2-OCH3 group takes the axial position. Only for the 2,2-pentamethylene derivative (10) was a minor amount (13%) of TB form detected. These results are markedly different from those found previously for the oxygen analogs and the conformational effect of the cyclic heteroatoms will be discussed in terms of the anomeric and steric effects.


This paper studies airlines' choices of flight frequency and aircraft size when passenger demand grows over time. The analysis shows that, when there are economies of operating larger aircraft, airlines would increase the number of flights, but not necessarily increase aircraft size to accommodate traffic growth. On the other hand, when there are no economies of operating larger aircraft, airlines would prefer operating larger aircraft to increasing the number of flights. The effect is stronger if the economies of aircraft size are more significant. These results hold whether airport charges are weight-based or flight-based, and are set exogenously or endogenously. © 2013 LSE and the University of Bath


Research into the level of mechanization of post harvest activities of rice in some rice production/processing areas of Kano State was conducted; with interest on studying the level of mechanization for each of the various processing stages involve in rice processing from harvesting to storage before the produce is taken to the market place. The Investigative Survey Research Approach (ISRA) was used, thus structured questionnaire was administered to rice processors in 4 major rice processing centres in Kano state through personal interview. The result of this study shows low level of mechanization of post harvest activities for all of the processing stages except de-husking which has 100% level of mechanization while other processing stages like harvesting, parboiling, and drying were seen to be at 0%, and threshing, winnowing and bagging at 8.14% level of mechanization with a stage like polishing being skip by majority. The result of the study can be utilize to conceptualize appropriate approach to improving post harvest activities of rice processors by focusing on the processing stages with low level of mechanization.

Current communications trends and social media have given individuals and organizations unprecedented opportunities to build relationships with audience members while introducing and encouraging new perspectives. One particular form of social media is blogging, which allows people to share a wider variety of information than other forms of social media. The purpose of this study was to explore how agricultural commodity organizations use blogs as a communication tool. The researchers purposively selected nine U.S. agricultural commodity groups that had an organizational blog and collected data through in-depth interviews. The findings indicated the organizations started blogging because blogs were the newest communication tool they could use to reach new and traditional audiences. The commodity organizations used some online analytics and mentions on other social media outlets to measure blog success, but they did not establish goals for their blog prior to the blog's launch. The findings offer an understanding of how agricultural commodity organizations are utilizing blogs, which provides insight for others in the agricultural industry who may decide to use this technology.

Every year the number of sexual abuse experienced by children in Indonesia continues to increase; this attracts the author's attention to study more deeply about legal protection for child victims of sexual crimes. In the Elucidation of Article 71 D Paragraph (1) of the Law of the Republic of Indonesia Number 35 of 2014 concerning Amendments to Law Number 23 of 2002 concerning Child Protection as amended by Law of the Republic of Indonesia Number 17 of 2016 concerning Stipulation of Government Regulations in Lieu of Law Number 1 the Year 2016, "Restitution" is the payment of compensation charged to the perpetrator based on a court decision with the permanent legal force for material and/or immaterial losses suffered by the victim or his heirs. From this study, it was found that there is legal protection for children who are victims of sexual crimes, namely through the Republic of Indonesia Law Number 17 of 2016 concerning the Stipulation of Government Regulations in Lieu of Law Number 1 of 2016 concerning the Second Amendment to Law Number 23 of 2002 concerning Child Protection. Became Law. The law regulates the right of restitution for child victims of sexual crimes. The implementation of granting restitution rights for child victims of sexual crimes is held in Article 71D paragraph (1) of the Law of the Republic of Indonesia Number 35 of 2014 concerning Amendments to Law Number 23 of 2002 concerning Child Protection as amended through Law of the Republic of Indonesia Number 17 of 2014 2016 concerning the Stipulation of Government Regulation in Lieu of Law Number 1 of 2016. It is further stated that the implementation of the right to restitution is precisely regulated in Government Regulation 43 of 2017 concerning the Implementation of Restitution for Children Who Are Victims of Crime. The performance of the right to restitution has obstacles. Three factors affect the effectiveness of the implementation of the right to restitution of children: legal, law enforcement, and community

Parallel processing has been considered as a cost-effective approach to make the EM algorithm computationally feasible. However, optimization of nonuniform data access pattern, which is an important descriptor for parallelization efficiency, has not been investigated thoroughly. It is well known that an improper allocation of the hot spots can seriously deteriorate a parallel algorithm due to the hot-spot contention problem. In this paper, we attempt to optimize the nonuniform data access pattern with uniform hot spots in a parallel EM algorithm by finding the optimal allocation for the hot spots. Also, the scheduling algorithms to achieve the optimal performance in cooperation with the optimal hot spot allocations have been developed. Three types of hypercubes have been considered in the study. They are uni- and bi-directional hypercubes as well as a hypercube with single-channel link capability. The optimal allocation of the hot spot for these three types of hypercubes has been derived deductively and the theoretical analysis results have been verified on an Intel iPSC860 parallel system.

The use of neural networks (NNs) for financial applications is quite common because of their excellent performances of treating non-linear data with self-learning capability. Often arises the problem of a black-box approach,i.e. after having trained neural networks for a particular problem, it is almost impossible to analyse them for how they work. The Fuzzy Neural Networks(FNN) allow to add rules to neural networks. This avoids the black-box but lacks of effective learning capability. To overcome these drawbacks, in this study a Integration of Genetic Algorithm and fuzzy neural networks (GFNN) are proposed to forecast corporation bankruptcy. The results indicate that the predictive accuracies obtained from GFNN are much higher than the ones obtained from NNs. To make this clearer, an illustrative example is also demonstrated in this study.


Round air jet development downstream from an abrupt contraction coupled to a uniform circular tube extension with length to diameter ratio L/D = 1.2 and L/D = 53.2 is studied experimentally. Smoke visualisation and systematic hot film velocity measurements are performed for low to moderate Reynolds numbers 1130 < Reb < 11320. Mean and turbulent velocity profiles are quantified at the tube exit and along the centerline. Flow development is seen to be determined by the underlying jet structure at the tube exit which depends on Reynolds number, initial velocity statistics at the tube exit and the presence/absence of coherent structures. It is shown that the tube extension ratio L/D as well as the sharp edged abrupt contraction influence the initial jet structure at the tube exit. For both L/D ratios, the presence of the abrupt contraction results in transitional jet flow in the range 2000 < Reb < 4000 and in flow features associated with forced jets and high Reynolds numbers Reb > 10. The tube extension ratio L/D downstream from the abrupt contraction determines the shear layer roll up so that for L/D = 1.2 flow visualisation suggests the occurrence of toroidal vortices for Reb < 4000 whereas helical vortices are associated with the transitional regime for L/D = 53.2. Found flow features are compared to features reported in literature for smooth contraction nozzles and long pipe flow. NEAR FIELD FLOW VISUALISATION A qualitative description of the flow development is given based on flow visualization as illustrated in Fig. 1. For the (a) Reb = 1131, L/D = 1.2 (b) Reb = 1697, L/D = 1.2 (c) Reb = 2829, L/D = 1.2 (d) Reb = 1131, L/D = 53.2 (e) Reb = 1697, L/D = 53.2 (f) Reb = 2829, L/D = 53.2 Figure 1. Instantaneous images of jet flow in the near field downstream the pipe nozzle, i.e. 0 ≤ x/D ≤ 5. long pipe nozzle, L/D = 53.2, a jet flow instability emerges at Reynolds number Reb = 2263 in accordance with the helical nature of laminar pipe flow for L/D > 40 [2, 5, 1]. The onset of instabilities in the range 2000 < Reb < 3000 is in accordance with observations of pipe flow issuing from a smooth long pipe nozzle in case a large disturbance is introduced at the inlet [5]. Therefore, the presence of an abrupt contraction at the pipe inlet can be seen as a geometrical disturbance reducing the Reynolds numbers associated with the transition regime compared to transitional Reynolds numbers Reb ≈ 10 observed for pipe flow in absence of such disturbances [5]. For L/D = 1.2, the flow structure depends on Reynolds number. For low Reb = 1131 the interaction of large scale structures and their deformation in the near field is limited. The presence of the abrupt contraction triggers the shear layer roll up at the nozzle exit so that generation of ring vortices is shifted upstream compared to a smooth contraction nozzle [4]. For Reb = {1697, 2263, 2829} a smaller tailing vortex is observed immediately behind a large leading vortex at x/D ≈ 1. The collapse of the two vortices into a single one at x/D ≈ 2 suggests a vortex pairing process to take place at a spatial position observed for transitional jet flow at high Reynolds numbers Reb > 10 as described by the two ring model for the axisymmetric jet issuing from a smooth contraction nozzle [3]. At Reb = 3961, large scale vortex formation and pairing are still observable. Nevertheless, the structure coherence is less evident than for lower Reynolds numbers. Increasing the Reynolds number beyond Reb = 4000 has for effect to limit the vortex size, and to quickly destroy them resulting in turbulent flow. SPECTRAL ANALYSIS OF THE VELOCITY SIGNAL The power spectral density of the velocity signal is illustrated for L/D = 1.2 in Fig. 2. The centerline spectra obtained for L/D = 1.2 are characterised by broad and sharp frequency peaks for which the spectral position and amplitude vary as function of Reynolds number Reb and measurement station x/D. For Reb = 1131, the spectra exhibit a broad frequency 0.37 3.7 37 10 −10 10 −5 10 0


Objective To study the islet function and the intervention effects of hypoglycemic drugs for obese and non-obese patients with the initial diagnosis of type-2 diabetes mellitus(T2DM).Methods 200 patients with the initial diagnosis of T2DM in our hospital from March 2011 to March 2012 were selected as study group and 80 healthy people with normal glucose tolerance in the corresponding period were selected as control group.Both groups of study subjects were divided into the obese group(BMI≥24 kg/m2) and the non-obese group(BMI24 kg/m2).The glucose and insulin levels during fasting and 30,60 and 120 minutes after dinner were determined using the oral glucose tolerance test(OGTT).The homeostasis model assessment of insulin resistance(HOMA-IR),insulin sensitivity index(SEN),homeostasis model assessment of β cell function(HOMA-β) and early secretion index(△I30/△G30) were also calculated.The patients with diabetes mellitus received the interventional treatment with Gliclazide for 1 to 3 months,after which the glucose and islet function changes of the patients were determined.Results In both the study group and the control group,obese patients had significantly higher HOMA-IR than non-obese patients,and the study group as a whole had significantly higher HOMA-IR than the control group,with statistically significant differences(P 0.05).In the study group,obese patients had lower SEN than non-obese patients at various glucose levels,with statistically significant differences(P 0.05),but had better △I30/△G30 and HOMA-β than non-obese patients at the same glucose level.After drug intervention,obese patients had significantly larger △I30/△G30 and HOMA-β changes and lower SEN change than non-obese patients,there were significant differences(all P 0.05).Conclusion For the patients with the initial diagnosis of type-2 diabetes mellitus,obesity can enhance insulin resistance and insulin secretion,and the islet function devastates with the elevation of fasting plasma glucose level.Drug intervention of the glucose level can significantly restore the secretory function of obese patients and the sensitivity recovery of non-obese patients is more significant.

Richard Larson in College Composition and Communication (his final issue as editor) questioned whether or not composition yet constitutes a "discipline." Too little of the work he has seen is the result of well-planned inquiry. In too much of that work, conclusions lacked the support of thorough investigation. He notes a "widening gap between composition researchers and teacher practitioners." A discipline, Larson maintains, ought to be "a field with a unifying conceptual framework, distinctive pattern of inquiry, and established standards of judgement about scholarship that many practitioners hold" (394). If current composition fit this definition, then perhaps it would be a lot easier for us to design writing curricula that serve our students rather than confuse them. Perhaps it would be easier for us to train teachers in consistent research-


Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer that does not have estrogen receptors, progesterone receptors, and HER-2 receptors. This subtype is found in 15-20% of all types of breast cancer, and it is often associated with a high recurrence rate and mortality after getting definitive therapy. The aim of our study is to investigate the clinicopathology of breast cancer in our center, where the majority were Bataknese.Methods: We evaluated the clinical and pathological characteristics of TNBC retrospectively from medical records data, from January 2017 to December 2019 with a total of 105 patients but only 79 patients had complete clinicopathological and immunohistochemistry data. This study was conducted in Murni Teguh Memorial Hospital, Medan, Indonesia. Results: From 79 TNBC patients, the average age at clinical presentation was 41-50 years group about 35 samples (44.3%). All patients had an invasive type of ductal carcinoma (100%). The majority of tumor size was T2 in 51 patients (64,6%), 83.6% grade 3 tumors. Both angioinvasion and lymph invasion were found in 48 patients (60.8%) while tumor-infiltrating lymphocyte (TIL) was found in 58 patients (73.4%), and 44 patients (55.7%) had lymph node metastases.Conclusions: According to some existing literature, TNBC showed more aggressive characteristics which are the same as our study. TNBC was diagnosed at young age, grade 3 tumors, having TIL which is very likely to occur distant metastases to lymph nodes.


In this research we developed a new traffic accident forecasting model on the basis of land use. A new traffic accident forecasting model by type was developed based on market segmentation and further introduction of variables that may reflect characteristics of various regions using Classification and Regression Tree Method. From the results of analysis, activities variables such as the registered population, commuters as well as road size, traffic accidents causing facilities being the subjects of activities were derived as variables explaining traffic accidents.


Metallic nanocantilevers of gold are fabricated from self-supporting polycrystalline thin film (100 nm) by focused ion beam assisted milling and ion induced manipulation processes. The surfactant assisted growth of the thin film leads to self-organized dendrite like morphology. This self-organized dendrite like morphology of the gold film imposes a new characteristic length scale corresponding to the mean size of gold grains present within the branches of the dendrite pattern in the film. The resonance characteristic investigated on cantilevers having different widths shows a significant drop in energy dissipation and hence an enhancement in the resonance amplitude at a characteristic width. At this width the resonance frequency of a vibrating cantilever approaches the theoretically expected value anticipated from an ideal cantilever treated like an elastic continuum.


Abstract : The use of chaos to transmit information is described. Chaotic dynamical systems, such as electrical oscillators with very simple structures, naturally produce complex waveforms. We show that the symbolic dynamics of a chaotic oscillator can be made to follow a desired symbol sequence by using small perturbations, thus allowing us to encode a message in the waveform. We illustrate this using a simple numerical electrical oscillator model.


In the 1830s, Schelling attributes to Hegel the pretense of constructing a logical system with total justification, as if it were obvious why there is a system or, indeed, anything rational or meaningful at all. The questions of why there is reason or meaning are permutations of the question 'why is there something rather than nothing'. This question is emblematic of Schelling's Hegel-critique and the source of his claim that reason is not self-justifying, but bounded by something other. What sort of claim is this? I argue that it is the conclusion to a transcendental argument in the Ages of the World, which holds that the past and future are conditions of the possibility of reason. This argument represents the past as the decision to construct a system and the future as the purpose guiding this construction. Schelling's claim against Hegel that reason is bounded by something other thus results from discovering reason's inescapable presuppositions.


A novel method of organism identification that can replace the conventional organism identification method by DNA requiring a large amount of labor. There has been developed a method of organism identification, namely, a method of identifying whether or not being a specified organism or a descendant thereof, characterized in that whether or not an identification object organism is a specified organism or a descendant thereof is judged by introducing in advance a DNA tag in cells of the specified organism or organism living parasitically or symbiotically therewith and finding whether the DNA tag is detected or not from the DNA extracted from the identification object organism or organism living parasitically or symbiotically therewith.


Natural cheese differs depending on the kind of milk and microorganisms used, as well as the conditions under which the cheese is matured. The purpose of this study was to examine a method of evaluating the aroma of bread with added natural cheese based on color, and to clarify the evaluation results and the correlation with volatile compounds. We made loaves of bread that each combined 13 kinds of natural cheese. We performed sensory evaluation of the aroma of the cheese bread using color. The aroma of bread was expressed as orange and yellow and the aroma of cheese bread was expressed as yellow. Principal component analysis identified the first principal component to be ‡toneˆ and the second to be ‡hueˆ. The first component was interpreted as ‡the strength and weakness of the baked aroma of the cheese breadˆ. The second component was interpreted as ‡the balance of the aroma of the breadˆ. Aldehydes and heterocycles had a negative correlation with pale and light color, and a positive correlation with deep color. We also visualized the aroma of cheese bread using words and components. We were able to suggest means of clearly conveying the aroma of cheese bread to consumers. (Received Sep. 25, 2019 ; Accepted Nov. 25, 2019)


At the heart of the performance analysis of linear motion control systems lie essential frequency domain characteristics such as sensitivity and complementary sensitivity functions. For a class of nonlinear motion control systems called convergent systems, generalized versions of these sensitivity functions can be defined. Incorporating such effective means in nonlinear motion control design requires efficient computation or estimation methods. In this paper we present a computationally efficient method for estimating these sensitivity functions for a class of convergent Lur'e type systems. The results are illustrated by application to an industrial example of a variable-gain controlled optical storage drive.


ITS1 (internal transcribed spacer 1) regions were amplified from 13 Chinese populations of Ditylenchus destructor and one Dutch population of Ditylenchus dipsaci. ITS1 regions of these populations were digested by five enzymes Rsa Ⅰ, Hae Ⅲ, Msp Ⅰ, Hinf Ⅰ and Alu Ⅰ. ITS1-RFLP patterns revealed that two patterns existed in 13 Chinese populations of D. destructor with different fragments obtained by four enzymes Rsa Ⅰ, Hae Ⅲ, Hinf Ⅰ and Alu Ⅰ, and ITS1-RFLP patterns of D. dipsaci and D. destructor were different in fragments obtained by all five enzymes. 13 Chinese populations of D. destructor were divided into two genotypes, i.e. genotype A and B. Genotype A included populations of DeSD1, DeSD2, DeSD3 and DeJS1, and genotype B included populations of DeAH1, DeAH2, DeHB1, DeHB2, DeJS2, DeSX, DeSD4, DeTJ1 and DeTJ2. ITS1 regions were also sequenced and the alignments showed that the pairwise sequence divergences of four populations in genotype A were between 1% and 4%, and that of nine populations of genotype B were 0 and 1%, and the sequence divergences of D. dipsaci and D. destructor were 39% and 48%. Morphometric characters were analysed on four populations of D. destructor and one population of D. dipsai. The results demonstrated that no significant difference in most morphometric characters except c, tail, V and V' among populations of two genotypes A and B of D. destructor. The ITS1-RFLP patterns, ITS1 sequence analysis and morphometric data supported that two genotypes of D. destructor were existed in China.

The Solar Ultraviolet Imaging Telescope (SUIT) is one of the payloads onboard the Aditya-L1 mission. It will perform full disk imaging of the Sun in the near-Ultraviolet wavelength range of 200-400 nm. This provides near-simultaneous observations of the Sun from the photosphere and chromosphere. A back-illuminated, enhanced UV Charge Coupled Device (CCD) of size 4096 (H) × 4136 (V) pixels, with a pixel size of 12 μm, is used as an imaging element in SUIT. The CCD characterization and the readout electronics development and testing were performed in-house at the Space Astronomy Group (SAG), UR Rao Satellite centre, ISRO. The test setup and procedures are explained and the measured values of various parameters including noise, dark current, gain, linearity, and cross-talk are presented in this paper. The results show a satisfactory performance from the CCD as well as the readout electronics to meet the specifications required by the SUIT payload.


In this paper, the effect of Gurney flap shapes on wind turbine blade airfoil S809 has been studied by numerical simulation. First, the O-type grid is used in the numerical simulation. By comparing with experimental data, such as the lift force, the drag coefficient, and the pressure distribution, the accuracy of the simulation method is validated. Second, the research on the widths of three kinds of rectangular Gurney flaps at the trailing edge of the S809 airfoil is carried out. Rectangular Gurney flaps can considerably increase the lift in both the linear and nonlinear sections, and the maximum lift coefficient can be increased by 20.65%. In addition, the drag and the pitching moment are increased. However, the width of the rectangular Gurney flap has a small impact on the lift, the drag, and the pitching moment. Finally, the effects of rectangular and triangular Gurney flaps on the aerodynamic characteristics of the S809 airfoil are compared. The results show that the triangular flaps can obtain an increase of maximum lift coefficient by 28.42%, which is better than 16.31% of the rectangular flaps.


Writing assessment runs the risk of sending the wrong message to students. Lab report grading that focuses on mechanical and format errors leads students to think that scientific report writing is a formulaic process: putting different information in the right sections, matching the number of the nouns with the number of the verbs. This approach leads to empty reports and does not give students insight into how one would assess scientific writing. Most importantly, this approach leads students to believe that they are writing reports as a classroom exercise rather than as an apprenticeship in a larger community of thinkers.


Helicopter is so flexible, that can perform special tasks which can't be completed by other aircraft or vehicle in the low altitude area. But the flight environment is complex in the low altitude area. Terrain, enemy air defense weapons, etc., seriously affect the flight safety. On the basis of the preprocessing of the terrain data in the mission area, the threat object is modeled, and the intelligent algorithm is used to plan the flight route. This method can assist the helicopter to avoid threats and improve the safety of flight. Simulation results verify the effectiveness of the proposed method.


Implantation of a sulcus-supported, pseudophakic supplementary intraocular lens (IOL) can be a safe and effective method for improving vision in eyes with residual refractive error after cataract extraction, refractive lens exchange, or keratoplasty, said Thomas Kohnen, MD, PhD. It also can be used to provide reversible presbyopia correction.


Description and Purpose: The V-22 Osprey is a joint service multi-role combat aircraft utilizing tiltrotor technology to combine the vertical performance of a helicopter with the speed and range of a fixed wing aircraft. With its engine nacelles and rotors in vertical position, it can take off, land and hover like a helicopter. Once airborne, its engine nacelles can be rotated to convert the aircraft to a turboprop airplane capable of high-speed, high-altitude flight. This combination allows the V-22 to fill an operational niche no other aircraft can approach. The Osprey can carry 24 combat troops, or up to 20,000 pounds of internal cargo or 15,000 pounds of external cargo, at twice the speed of a helicopter. It features a cross-coupled drive system so either engine can power the rotors if one engine fails. For shipboard compatibility, the rotors fold and the wing rotates to minimize the aircraft's footprint for storage. The V-22 is the only vertical lift platform capable of rapid self-deployment to any theater of operation, worldwide. Customers: The U.S. Marine Corps has a current requirement for 360 MV-22s to perform combat assault and assault support missions. The U.S. Air Force Special Operations Command has a requirement for 50 CV-22s configured for terrain-following, low-level, high-speed flight for long range special operations. More than 200 Osprey tiltrotors are currently in operation across 10 Marine Corps and two Air Force Special Operations Command Osprey squadrons. The two services have together logged 16 successful combat, humanitarian, ship-based or Special Operations deployments since 2007. The worldwide Osprey fleet has amassed more than 190,000 flight hours, with more than half of those hours logged in the past two years. Safety, survivability and mission efficiency have become hallmarks of the operational fleet. According to Naval Safety Center records, the MV-22 has one of the lowest Class A mishap rates of any tactical rotorcraft in the Marine Corps during the past decade. Navy flight-hour cost data also show that the Osprey has the lowest cost per seat-mile (cost to transport one person over a distance of one mile) of any U.S. naval transport rotorcraft in each of the last two years.


The US Allowance Trading Program, which is an emission-trading program for sulfur dioxide, was put into effect on 1 January 1995. It is the first comprehensive attempt in US air-quality policy to practice the idea of emission trading. More than two years after its implementation, the allowance market offers the unique opportunity of evaluating the efficiency of tradeable-permit markets on a practical basis, rather than a solely theoretical one. The author analyzes the recent developments in the allowance-trading market and alternative 'explanations' used in attempts to explain low trading activity and low allowance prices. The author concludes that the present allowance price will prove to be equal to the abatement costs; the allowance-trading program is not only ecologically effective but is also economically efficient; and it plays an important role in the development of future tradeable-permits markets.


By employing 3D photoelasticity method and ANSYS software, the stress distribution of the railroad slanting crossed bridge with rigid continuous beam were analyzed for four loading cases, that is two different selfweight in different period and two different working load cases. Two computing models representing the experimental model and real bridge respectively are used in numerical analysis. Results show that the bridge has its special character of obviously nonsymmetry stress distribution, although with a symmetry structure and load.


The crystal and molecular structure of bis(tetraphenylarsonium) bis(maleonitriledithiolato)tellurate(II), a new tellurium(II) compound containing dithiolene ligands, and the single-crystal e.s.r. spectra of the system [AsPh4]2[63Cu/Te(mnt)2] are reported. [AsPh4]2[Te(mnt)2] crystallises in the triclinic space group P, with a= 10.211 (2), b= 14.460(2)A, c = 18.583(3)A, α = 105.95(2), β = 95.60(2), γ = 77.67(2)°, and Z = 2; R= 0.047 for 7749 observed reflections. The tellurium atoms have trapezoid planar co-ordination with Te–S bond distances of 2.501(1), 2.482(2), 2.971(2), and 3.104(2) A. In the single-crystal e.s.r. spectra the signals of two Cu sites with somewhat different spin-Hamiltonian parameter sets are observed. The and the 63Cu hyperfine tensors are rhombic symmetric. The planar [Cu(mnt)2]2– anions are considerably distorted but do not adopt the structure of the tellurium host.


A comparison of hind limb weight-bearing for standard hip excision (EX) vs. modified deep gluteal excision (MDG) was performed in sixteen hips of eight dogs. Using force plated technology, maximum vertical force was determined in each hind limb at a walk before and at two and four months after the operation. Recovery with both techniques was 67% at two months and 84% at four months after the operation. In conclusion, transfer of a portion of the deep gluteal muscle to the femoral osteotomy site appears not to halve any advantage over standard hip excision. The original deep gluteal transfer technique was not compared. A portion of this report was presented at the 1995 Veterinary Orthopedic Society meeting, Whistler, B.C. Canada


The Meteorological Development Laboratory (MDL) of NOAA's National Weather Service (NWS) is developing a National Digital Guidance Database (NDGD) at a resolution of 5 km to complement the existing National Digital Forecast Database (NDFD, Glahn and Ruth 2003). To help accomplish this goal, MDL is creating a gridded forecast guidance system. Current forecast guidance is produced for the United States and its territories at approximately 1700 hourly observing sites and over 5000 cooperative observing sites by using the Model Output Statistics (MOS) technique (Glahn and Lowry 1972). In the MOS approach, observed predictand data are statistically related to predictors such as forecasts from dynamical models, surface observations, and geoclimatic information. MOS guidance depends on a sufficiently long sample of high-quality observations to develop robust forecast equations for a variety of weather elements (Allen 2001).


T-odd correlations in $Wj$ production at the LHC have been studied recently as a way to measure a phase produced by QCD at NLO by Frederix et. al. That study found that the induced asymmetry could be observed with 20 fb$^{-1}$ of 8 TeV data. These T-odd asymmetries can also be induced by CP violating new physics interfering with the SM at LO. In this paper we study this possibility using effective Lagrangians to describe the new physics. We find that the leading contribution arises at dimension eight, and that it necessarily introduces flavor changing neutral currents as well. We discuss the constraints that can be placed on the flavor structure of the new physics operator from studies of FCNC in kaon and B meson decays and then compare the T-odd correlations in $Wj$ induced by CP violating new physics to those induced by QCD at NLO. We quantify the level at which these couplings can be probed at the LHC, and find that they will not affect a measurement of the NLO QCD phases.


he introduction of troponin measurement into clinicalpractice in Australia 10 years ago led rapidly to its wide-spread use as the marker of choice for diagnosis and riskstratification of patients with acute coronary syndrome (ACS).However, opportunities remain for improving risk assessment in"troponin-negative" patients, many of whom will have adverseevents. This has led to the development of new, improved assaysthat are able to measure down to much lower concentrations thanbefore (10–100-fold lower than current assays), and that increasethe detection of acute myocardial infarction, as shown in tworecent cohort studies.

Cyclization of N-acyl-2-hydroxy-2-(trifluoromethyl)arylethylamines 4 under Pictet-Gams conditions afforded 2-oxazolines 5 instead of the expected isoquinolines 6. The effect of the trifluoromethyl group on the result of the reaction is discussed.


The advanced water treatment taken by organic micro-pollution water resource has been a question of common interest. In this article, the effects on tap water, aniline,nitrophenol and humic acid when using ultraviolet-ozone combined technology were discussed. Meanwhile, it was compared with the effect of ultraviolet or ozone alone. The conclusion that ultraviolet-ozone combined technology has the best effect was drawn. At the same time, the meaning and its application prospect were elaborated.

In conditions of the extreme increase in threats to Russia's national interests and unprecedented sanctions pressure, import substitution is an unambiguous priority of the country's economic development. At the same time, the need for significant and reliable forecast of import substitution effectiveness and its impact on economic growth in Russia comes to the fore. This forecast allows to do variant calculations of economy and its industries requirement of the import substitution; to determine, based on the actual or required indicators of the scale and economy's growth rate, the rational structure of the country's foreign trade turnover, the optimal ratio between domestic production, exports and imports, the level of employment and household income both at the macrolevel and in the context of individual industries and commodity groups, taking into account the real situation in the economy. The import substitution effectiveness was calculated with using multicomponent analysis; the forecast of the import substitution effectiveness and its impact on economic growth was carried out using the regression modeling method in two directions: 1) forecast the values of complex indicator of import substitution, leading to a given GDP growth; 2) a point forecast of the import substitution effectiveness parameters, ensuring the strengthening of its positive impact on economic growth in Russia, solving the optimization problem. The results can be used in the activities of public administration aimed at adjusting the country's socio-economic development plans and effective import substitution program development.


The short-term frequency stability of quartz crystal oscillators is of great importance. We show how this can be extended to the long-term in an oven-less, low-power configuration, by surmounting the basic problems due to temperature, adverse effects due to shock, vibration and general acceleration effects, inherent frequency inaccuracy, and lastly, oscillator frequency and time jumps, activity dips and drop outs. The design goal is to reduce the size of all of these effects by one to two orders of magnitude. This is accomplished by using an ensemble of inexpensive oscillators, such as TCXOs or MCXOs. The lead or lag hysteresis effects in TCXOs seem to be ameliorated in this approach. In addition, the use of TCXOs reduces the temperature compensation to a second order fit problem. The CTXO oscillator (clock) is designed to be inexpensive, environmentally insensitive, robust, adaptive and small. The performance goal is about 10/sup -8/ from -35 to 85/spl deg/C, and analysis shows that, with a good choice of optimization routine, it is possible to get excellent temperature compensation using a multiplicity of oscillators, a generic TCXO (or DTCXO) compensation, followed by good second-order compensation.


PurposeThis research aims to bridge the gap in the literature by developing a model to investigate individual work performance (IWP) within small and medium enterprises (SMEs) using soft organizational memory (OM) and additionally aims to test the role of learning and growth (LG) as a mediator in this relationship.Design/methodology/approachA questionnaire survey was developed and adopted from previous studies and distributed to a sample of 320 employees from middle and bottom management levels in Jordanian SMEs. Data were collected and analyzed to test the proposed model employing structural equation modeling (SEM) through AMOS23.FindingsThe study finds that soft-OM positively and directly impacts IWP and LG. Besides, the results show that LG directly affect IWP. Surprisingly, LG mediate the relationship between soft-OM and IWP within SMEs.Practical implicationsEstablishing a store for internal knowledge in such a progressively active environment is probably inadequate; however, knowledge needs to go beyond that among the firm and external structures such as clients, business allies and education and research organizations. This, in turn, will allow building streams of knowledge, consequently attaining an adequate level of performance.Originality/valueThe originality of the current study departs from the fact that stock and flow of knowledge are different. The knowledge stock is the collection of human capital that an organization's employees retain, such as employees' knowledge, capabilities and skills. In contrast, the flow of knowledge expresses the practices that allow the transfer of competence and experience across time, geography and organizations. The current research findings propose that the decomposed approach helps understand the multifaceted associations represented in the knowledge management (KM)–performance linkage that cannot be speculated utilizing a complex model.


The problem of how to compare repairable systems has long been of interest to those who are engaged in reliability analysis. In this article we have introduced a type of comparison of two counting processes. Various properties and applications of our stochastic comparison are also studied.


Discusses the way in which new embedded RISC architectures have evolved. Basic attention to the future requirements of real-time critical tasks have paved the way for an imaginative cornucopia of new 8, 16 and 32 bit MCU architectures to address the most demanding of real-time embedded system applications. The combination of reduced component costs, reduced power consumption, fast product design cycles and therefore earlier time to market are all absolute imperatives for future embedded applications.


The mechanisms of UV induced decomposition of oxygen-deficient centers (ODC) in silica glass has been experimentally studied. It is shown that high intensity irradiation of silica glass results in the two-step decomposition of ODC and formation of paramagnetic E' centers. At the same time at low UV irradiation intensity (laser, mercury lamp) the single quantum reaction of ODC with gas-phase impurities in the net of silica is the dominant process of ODC photoreaction.


The work of community engagement performed by public officials in local government provides valuable opportunities for city residents to participate in governance. Technology stands to play an increasingly important role in mediating community engagement; however, currently the practices and relationships that constitute community engagement are understudied in HCI. Of particular importance is the role trust - either establishing trust, or more frequently, overcoming distrust between public officials and city residents. To address this challenge, my research seeks to understand how trust could inform the design of technology to support the work of community engagement performed by public officials in local government. My research will culminate in a design framework that will inform development of technology for community engagement using trust.


media security is the principal concern in the today's technological world. Due to easy production, transmission and dissemination of digital data, security threats occur while dealing with digital data. Digital watermarking is one of the growing and promising technologies to protect the digital data from being tampered and also widely used for copyright protection. Several watermarking techniques in spatial and frequency domain were given by various researchers which suffered from problems of poor robustness and fidelity. The evolutionary techniques using genetic algorithm provide an alternative way of creating watermarks with promising values of robustness and fidelity aspect of watermarking. This paper deals with design and development of a new watermarking technique which uses genetic algorithm to identify locations within the cover image for watermark insertion in spatial domain and then apply the average neighborhood concept for the purpose of watermark insertion and extraction ensuring higher fidelity and robustness and resilience to several possible image attacks. Genetic search often produces same watermark locations in different populations for watermark insertion resulting in poor value of fidelity and robustness, which need to be checked. Sliding window concept introduced in this paper uses a set of a few genes which are serially shuffled to get new set of locations for watermarking during each population generation and helps in enhancing robustness and fidelity aspect of watermarking. Tournament selection has been used while using the genetic algorithms developed in the paper.


Summary

Six accessions [three with maroon-coloured seed coat and three with white-coloured seed coat) of sword bean (Canavalia gladiata (Jacq.) DC.], were collected from six different locations in south India. They were analysed for their proximate and mineral composition, amino acid profiles of total seed proteins, in vitro protein digestibility (IVPD) and certain antinutritional factors. The essential amino acid profile of total seed proteins compared favourably with FAO/WHO requirements, except that there were deficiencies of sulphur containing amino acids in all the six accessions and also the leucine, lysine and tryptophan contents were low in maroon-coloured seed coat accessions. The IVPD of the accessions ranged from 63.39 to 76.92%. Antinutritional substances like total free phenolics, tannins, l-DOPA (3,4-dihydroxyphenylalanine), trypsin inhibitor activity and phytohaemagglutinating activity were also investigated. The antinutritional factors that were detected were thought to have little nutritional significance if the beans are properly processed.


The Equal Protection Clause of the Fourteenth Amendment states that the defendant in the courtroom is meant to have a jury that is largely representative of the local community in which the trial is held. This raises the question of whether juries are representative of the population in which they reside. To analyze this question, I compare the demographics of the 87 counties in Minnesota gather and analyze data from the Minnesota Judicial Branch's Committee of Equality and Justice (Wahi et al., 2021). The results show that there are discrepancies at each stage of the jury process. Additionally, they show that though the jury pools are somewhat representative of their population, the seated juries are typically not. The analysis raises more questions as to why these discrepancies occur, whether it be racially motivated elimination during the voir dire process or exemptions from jury duty due to disqualifications (e.g., language barriers, residency).


The effects of sulphur on grain protein content and storage protein content were studied by using six cultivars differing in quality under the different amount of nitrogen. The results showed that sulphur influenced grain protein and storage protein contents under the condition of nitrogen amount 60 kg/hm 2 and 128 kg/hm 2 urea. The grain protein content of cultivars with HMW-GS composition 2+12 got higher level in the treatments of 60 kg/hm 2 urea with optimum sulphur application and HMW-GS composition 5+10 reached higher in 128 kg/hm 2 urea with certain sulphur application. The study indicated that the effect of sulphur on protein and quality depended on the amount of nitrogen application. Under the condition of higher-level nitrogen, sulphur enhanced the content of grain protein, especially to the cultivars with high grain protein and good quality. Sulphur had positive effect on gliadin under 60 kg/hm 2 urea application. Sulphur could enhance grain glutenin content especially under higher nitrogen application. Among cultivars with high grain protein and good quality, NE7742, Roblin and Neepawa got higher glutenin content under nitrogen 128 kg/hm 2 than 60 kg/hm 2 application. Nitrogen was the limit factor to sulphur for these cultivars. But for IE74 and Liao10 with high grain protein and good quality and NKH9 with low grain protein and poor quality higher glutenin content was achieved under 60 kg/hm 2 urea application. It showed that if sulphur was used improper under higher nitrogen application, the content of glutenin was lower than lower nitrogen application with optimum sulphur application. But this was relating in cultivars.


As part of a wider search for radio emission from nearby systems known or suspected to contain extrasolar planets, ϵ Eridani was observed by the Jansky Very Large Array (VLA) in the 2–4 GHz and 4–8 GHz frequency bands. In addition, as part of a separate survey of thermal emission from solar-like stars, ϵ Eri was observed in the 8–12 GHz and the 12–18 GHz bands of the VLA. Quasi-steady continuum radio emission from ϵ Eri was detected in the three high-frequency bands at levels ranging from 67 to 83 μJy. No significant variability is seen in the quasi-steady emission. The emission in the 2–4 GHz emission, however, is shown to be the result of a circularly polarized (up to 50%) radio pulse or flare of a few minutes in duration that occurred at the beginning of the observation. We consider the astrometric position of the radio source in each frequency band relative to the expected position of the K2V star and the purported planet. The quasi-steady radio emission at frequencies ≥8 GHz is consistent with a stellar origin. The quality of the 4–8 GHz astrometry provides no meaningful constraint on the origin of the emission. The location of the 2–4 GHz radio pulse is >2.5σ from the star; however, based on the ephemeris of Benedict et al., it is not consistent with the expected location of the planet either. If the radio pulse has a planetary origin, then either the planetary ephemeris is incorrect or the emission originates from another planet.


Aim:  The goal of this study was to develop and implement methodology that would aid in the analysis of extended high‐density single nucleotide polymorphism (SNP) major histocompatibility complex (MHC) haplotypes combined with human leucocyte antigen (HLA) alleles in relation to type 1 diabetes risk.


A total of 127 faecal samples were collected from diarrhoeic lambs and examined for Escherichia coli. The bacterial culture involved pre-enrichment in peptone water before C incubation at 37 for 24 hours. Out of the isolates obtained, 42 (36.84%) were positive for Escherichia coli. Characterization of the isolates revealed serotypes O157 (13), O118 (9), O111 (8), O26 (7), and O103 (5) as the most frequent strains. Their prevalence rates being 31.0%, 21.4%, 19.0%, 16.7% and 11.9% respectively. Minimum Inhibitory Concentration (MICs) of the E coli strains to six antibiotics revealed tetracycline as having the lowest MIC, which ranged from 3.12ig/ml - 50ig/ml followed by chloramphenicol with an MIC ranging between 6.25ig/ml - 100ig/ml. It was concluded that there was need for further research to study the pathogenicity of the E coli strains and that resistance to antibiotics was a problem which might have resulted from indiscriminate use of these drugs.


We have investigated the growth shape of two-dimensional (2D) poly(ethylene terephthalate) spherulites using a transmission electron microscope technique in order to examine the role of a diffusion-controlled mechanism in the growth process. At the growth front of the 2D spherulites, we found a terrace-like morphology having a single crystal structure. The growth front of the terrace shows instabilities of periodic or groove patterns which can be explained by the diffusion-controlled theory for crystal growth.

An on-chip implementation of a W-band filter with dual notches at 82 and 95 GHz is presented. Reflection mode filtering methods are implemented with dual hairpin resonator networks, using the inherent parasitic losses in the resonators to create matched loads at the stopband frequencies of interest while reflecting passband power. Notches of 6 and 10.6 dB stopband insertion loss, and 3.7 and 5.6% relative bandwidths, respectively, were achieved. This represents the first implementation of reflection mode filtering in the W-band on-chip.


A polydiacetylene nanowire fabricated on a highly ordered pyrolytic graphite surface was studied by scanning tunneling microscopy/spectroscopy (STM/STS). The spectroscopy of individual polydiacetylene nanowires revealed the theoretically predicted π-band and band edge singularities, which are characteristics of a one-dimensional π-conjugated polymer. Furthermore, under a high electric field intensity applied to the polymer wire, the spectrum shows a narrow band gap caused by polaron injection. When a much higher electric field intensity was applied to the wire, an avalanche current flow that rises abruptly has been observed. We consider that such a large current flow originates from an electrical property of the polymer wire, which was changed by a dynamical modulation of the injected polaron.


M ILLER'S INTERESTING ARGUMENT is a good example of a class of alternative explanations of saving-investment correlations. The basic idea behind these arguments is that sources of independent shocks to national saving and investment rates that are thought to be important quantitatively are either not independent or are not shocks at all. In this case, it is argued that there are good reasons to believe that changes in debt-financed government expenditures are fully offset ex ante by changes in an ultrarational private sector's saving and investment behavior. Thus, from the point of view of international capital markets, no disturbance will be observed. A similar argument is that, although there are various shocks to the system that appear to require net saving flows across countries, these shocks are fully dissipated by changes in relative prices so that no observed intertemporal trade is predicted. In general, we find these arguments interesting but, so far, unconvincing. In reference to Miller's argument, we would assume that there are other shocks to national saving and investment rates, in addition to changes in governments' saving and investment behavior. An ultrarational private sector might neutralize changes in government behavior,


In this survey we provide an overview of some recent developments in the construction of moduli spaces using stack-theoretic techniques. We will also explain the analogue of Harder-Narasimhan stratifications for general stacks, known as $\Theta$-stratifications. As an application of the ideas exposed here, we address the moduli problem of principal bundles over higher dimensional projective varieties, as well as its different compactifications by the so-called principal $\rho$-sheaves. We construct a stratification by instability types whose lower strata admits a proper good moduli space of ``Gieseker semistable"objects and a new Gieseker-type Harder-Narasimhan filtration for these objects. Detailed proofs of the latter results will appear elsewhere.


The overall structure of LMC3308 large gantry machining center is taken as the object of study. Application of top- down design method in large gantry machining center based on motion skeleton model of Pro/E is introduced. Besides,this design idea and method is consistent with the product design process and the designer's way of thinking. It can also realize design goals and satisfy design requirements,which can easily realize centralized management of product information. At the same time,it is an efficient way of development of product design as the serialization design of production can be realized more easily. Finally,as this method supports concurrent design,it can effectively improve design efficiency and product quality,reduce production cost,and enhance the market competitiveness.


The failure rate of XLPE cable terminations is much higher than that of the cable body. In order to solve the operational failure problem of the high voltage cable terminals, the conjunction of ultrasonic method and pulse current method are tested on the polyethylene material and the cable terminal in the lab. When the voltage of 6kV is applied on the cable, the partial discharge will occur at the cable terminal. The amplitude of the voltage detected by the pulse current method is about 20mV and the result detected by ultrasonic method is about 80mV. The test data show that the comprehensive application of the ultrasonic and pulse current method can improve the measuring accuracy of the partial discharge results. It can suppress interference effectively and achieve an accurate diagnosis of the partial discharge sources. INTRODUCTION The terminals of the high voltage power cable play a very important role and function in the whole process of power supply and distribution. 1 Most of the insulation faults of power cables come from the failures of the cable terminals. The operation faults caused by the cable accessories account for more than 70% of the total faults according to the relevant statistical information. 2 Therefore, it is necessary to detect the insulation state of the cable terminals. At present, the detection technologies of partial discharge are various. The ultrasonic testing method for the partial discharge of the cable terminal can overcome the electromagnetic interference effectively and it is convenient to operate without the need of power failure. 3 The HFCT is used to extract the partial discharge signal in the pulse current method and it is very convenient and widely used. 4 In this paper, the combination of ultrasonic and pulse current method are used to test the partial discharge of cable terminal, which can effectively detect the development trend of PD and eliminate potential hazards.

There has been much resistance on the part of some women to involving men in gender and development work - driven by fears about the dilution of the feminist agenda and by anxieties over the diversion of limited resources away from womens empowerment initiatives and back into the hands of men. Yet not engaging with men and boys may limit the effectiveness of development interventions and may actually intensify gender inequalities. Development interventions which aim to improve womens employment and income generating opportunities for example are likely to compound womens heavy work burdens unless efforts are made to encourage men to take greater responsibility for child care and domestic chores. Projects that focus solely on women may also reinforce existing gender stereotypes (women as carers men as breadwinners and so on). Involving men by contrast can generate a broader consensus on issues which have previously been marginalised as being of interest to women only - sexual and reproductive health for example. The inherent weakness of women-only approaches has become most devastatingly apparent in the light of the HIV/AIDS epidemic. Programmes that focus on empowering women to negotiate safer sex have minimal impact in societies where it is men who decide when and with whom to have sex and when an d if to use condoms.

The opening paragraph of this important book states its intentions: 'This monograph is about welfare (well-being) and its relation to social policy. Thus we shall be interested in the concept of welfare, the way in which concepts of welfare have been incorporated into social policies, how social welfare could be measured, and so on.' Its concluding paragraph declares that 'The central questions of human welfare are not solved by models, by bureaucrats, technocrats, and scientists, they are solved by men themselves perhaps with the aid of social science not through social indicators or welfare measurements, but through changes in the social consciousness, in the conscious activities of men to improve their lot.' The sureness of the conclusion (with which I agree) does not spring from the analysis; that is a pity. It reduces this book from a substantial contribution to the sorely needed development of theory about social policy to an immensely useful review of many literatures which touch on social policy. To link his opening and closing paragraphs this Finnish scholar first discusses the need for 'policy science' and then analyses those two murky concepts of welfare and need. Not much is learned from this unavoidably shadowy appraisal, especially as the author suddenly drops anchor in a dramatic and unadorned footnote: 'Finding the objects of need is certainly the fundamental objective of social policy.' The heart of the book is then an analysis of the literature of 'policy science', welfare economics and social indicators. Roos may disagree with this interpretation of what he has done. It seems to me that he has collapsed his avowed search for a theoretical and scientific basis for social policy into a concern with the more specific, limited and United States-centred 'policy science' approach currently spearheaded by Yehezkel Dror, an Israeli whose work is most warmly received in the United States. Roos has, at least in many parts, connected his search for theory with what 'policy science* adherents are concerned with and then at the end of the book he has


have had a partial radial nerve lesion, affecting the motor fascicles at the more proximal site (mid humerus) indicated in the illustration. When discussing the mechanism of the nerve injury, the authors state, 'This, together with the subsequent spontaneous recovery of the nerve, is suggestive of a progressive compressive neurapraxia, possibly by haematoma'. The use of the term 'neurapraxia' is incorrect. The EMG had shown denervation of the extensor muscles of the forearm indicating axonal degeneration. Therefore the nerve lesion was an axonotmesis and, indeed, the time of one year for recovery would be more consistent with that type of injury.


T issue culture is a way of growing plants as isolated, undifferentiated cells. Sych cells can divide indefinitely in culture and in many cases be induced to regenerate to whole plants, so that millions of clones can be produced from a single plant. The fact that plants can be propagated as single cells or clumps of cells presents a unique opportunity to apply the concepts and techniques of microbial genetics to plants. The objective of performing agricultural genetics in the laboratory is to generate novel phenotypes by single-cell manipulation and biochemical selection. While conventional geneticists make sexual crosses at the whole plant level, somatic geneticists work with single cells grown in aseptic culture. Typically, small segments of a root or stem are stimulated to dedifferentiate and divide, generating a disorganized mass of cells, or callus. Callus can be placed in liquid shake culture to disperse the cell aggregates and grow as a fine suspension of cells. Plant cells are normally surrounded by a rigid polysaccharide cell wall, which literally holds the plant together. Leaves and suspension culture cells can be treated with enzymes to dissolve the cell wall, liberating millions of naked cells-protoplasts. The protoplasts, under appropriate conditions, will replace the cell wall and divide again. At this point they can be maintained in tissue culture or regenerated to plants. It can be seen from the diagram that all cultural steps are potentially reversible. Thus, suspension cells or protoplasts can be genetically altered, and whole plants regenerated. Genetic modification can be accomplished by changing the original or introducing foreign genetic material. Methods of somatic genetic manipulation include: UMutant isolation. The capability of applying biochemical selection to a large, nearly homogenous population of cells grown in a dish allows efficient recovery of rare events like genetic mutants. In this manner, mutants of immediate application, such as herbicideresistant strains, have been isolated. In other instances, mutants altered in biochemical pathways have been found. These are useful in studying the normal cellular processes and can serve as genetic markers for somatic hybridization and transformation experiments. 0 Somatic hybridization. The simplest way to combine genetic information of two cells is through fusion of their protoplasts. The resulting product is the sum of the two nuclear and cytoplasmic genomes. However, subsequent elimination of the genetic material from one or both parents often occurs. The somatic cross is a critical step in a somatic genetic system, and it has been successfully employed in complementation and dominance-recessiveness tests. Somatic crosses are useful in overcoming sexual incompatability between some related species. Although wide crosses often result in abnormal development and cytogenetic abnormalities in the hybrid, it is still possible to make somatic crosses wider than can be made by conventional means. Besides the nucleus, the cytoplasm also contains genetic information which is located in subcellular bodies-organelles, such as chloroplast and mitochondria. Usually the cytoplasm of pollens is not transferred to the eggs during fertilization; thus genetic exchange between organelles does not occur. On the other hand, cytoplasms in nuclei of both partners are mixed during protoplast fusion. This method enables the transfer of cytoplasmic traits such as male sterility from one plant species to another. OTransformation. In this method, cells or protoplasts are treated or injected with DNAcontaining material to transfer the encoded genetic information to the recipient cell. The foreign DNA could potentially be isolated chromosomes, DNA enclosed in membrane vesicles, organelles, specific gene(s) cloned in vectors, or even naked nuclear DNA (see vector section). The DNA is usually introduced via the uptake into protoplast or fusion between the organelle or vesicle membranes and that of the recipient protoplast. Protoplasts are usually used in these experiments to avoid problems of penetration through the cell wall, although the development of microinjection and other novel techniques might overcome this limitation. The major advantage of transformation over protoplast fusion is that far smaller amounts of DNA are transferred, even single genes. It is considered less likely to result in abnormal products than the mixing of two entire genomes. The problem is that the tech-

The functions of splices and connectors are to interconnect the transmission media and to connect the media to optical devices. Splices are for the most part intended to stay permanently connected, although some designs offer the opportunity of separation and rejoining. Connectors, on the other hand, are designed for frequent separation and rejoining. Connectors may possibly require cleaning when rejoined, whereas splices require replacement of matching gels or adhesives and possibly repolishing. The most operationally significant system parameter of these components is optical loss. The loss is dependent on alignment of the fibers, the end conditions of the fibers, and the fiber-core parameters (primarily core diameter and peak index difference in multimode fibers and mode-field diameter in single-mode fibers). These fiber-core parameters are not under the control of the splice or connector design and will not be covered further here.


At the turn of the twentieth century, the society of Szekszárd was divided into two broad socio-economic groups with identities distinguished by occupation. A "market-town block" was composed of small producers whose existence was based on physical labor: farmers, artisans, and the lowest ranks of the tradesmen, as well as the poor peasantry, day-laborers taking a part in small production, and the small-town workers. The other grouping consisted of people working in state and private administrative jobs, as well as of intellectuals, who began to appear in this community from the eighteenth century onward. Starting in the final decades of the nineteenth century, disintegrative processes—including social mobility and migration—can be detected quite clearly in the market-town block, and these are investigated with the aid of sources from the Orphans' Ward. The models of mobility in the traditional market-town structure emerge clearly from these data.


Cucumber is an important vegetable crop grown year found for salad and pickling purposes. There is a need to develop and identify the genotypes, which can successfully be grown during summer and Kharit season. Response of cucumber genotypes to range of environmental conditions is an important step in the development of improved varieties. The selection of improved varieties is often inefficient due to genotype x environment interaction. Genotypes grown in multienvironmental trials may react differently to a range of climate conditions, soil characterstics or technical practices ( Lacaze and Roumet, 2004). Several methods have been proposed for determining the stability of varieties tested under different environments (Eberhart and Russell, 1966; Perkins and Jinks, 1968) and to get reliable estimates of genotype x environment interaction. A attempt has been made to identify the stable genotypes of cucumber with desirable characters for commercial cultivation.


The development of supervised deep learning technology in seismology and related fields has been restricted due to the lack of training sets. A large amount of unlabeled data is recorded in seismic exploration, and their application to network training is difficult, e.g., fault identification. To solve this problem, herein, we propose an end-to-end training data set generative adversarial network Fault2SeisGAN. This network can expand limited labeled datasets to improve the performance of other neural networks. In the proposed method, the Seis-Loss is used to constrain horizon and amplitude information, Fault-Loss is used to constrain fault location information, and the Wasserstein distance is added to stabilize the network training to generate seismic amplitude data with fault location labels. A new fault identification network model was trained with a combination of expansion and original data, and the model was tested using actual seismic data. The results show that the use of the expanded dataset generated in this study improves the performance of the deep neural network with respect to seismic data prediction. Our method solves the shortage of training data set problem caused by the application of deep learning technology in seismology to a certain extent, improves the performance of neural networks, and promotes the development of deep learning technology in seismology.


Cybernetics studies the systems of communication and automatic regulation of living things and applies them to electronic and mechanical systems that resemble them. The objective is to determine if the cybernetics improves the educational system in the Educational Institution "Julio Gutiérrez Solari", El Milagro-Period 2016. We used the quantitative method, with a pre-experimental design and at the same time it is propositive, for which the questionnaire was applied to teachers and students to explain the improvement of the educational system in classes. Computers, overhead projector and educational software were used as materials, which were necessary to carry out the research. As a result, it was obtained that, cybernetics significantly improves the educational system in the Educational Institution "Julio Gutiérrez Solari", El Milagro-Period 2016; That is why tables and figures were used to demonstrate such research. It was obtained as conclusions that, cybernetics significantly improved the educational system in the Educational Institution, based on responses: 62,50% (teachers); also 74,29% (students); So the research hypothesis is accepted.

Expatriate managers work alongside increasingly sophisticated and experienced local managers in many parts of the world, yet few researchers have examined the dynamics of the relationship between expatriates and local managers, or the attitude of local staff to their expatriate colleagues. This article seeks to redress this by reviewing existing research, and by drawing on the perceptions of Singaporean managers, highlights the tensions between local and expatriate managers and reflects some of the issues faced by multinationals who continue to employ expatriates in countries where there is sufficient indigenous management talent.

This research proposes an OpenFlow (OF) segment routing (SR) control-plane software-defined network (SDN) to reduce the number of control messages between the source and destination hosts. In the study, the conventional OpenFlow SDN and the proposed OpenFlow SR SDN were emulated and assessed under three network configurations: tube, shortest path and load balance. The results revealed that the number of control messages between source and destination under the conventional OpenFlow SDN was halved (approximately 50%) under the OpenFlow SR SDN, indicating the superiority of the proposed scheme over the conventional technology.
