Two experiments were conducted to study the response of boars, gilts and barrows to increasing levels of dietary crude protein and digestible energy. In the first experiment boars, gilts and barrows were fed diets ranging in crude protein from 14.6 to 22.7 per cent in restrictive amounts between 20 and 70 kg liveweight. Growth rate and food conversion efficiency measurements ranked the sexes in order of superiority as boars, gilts and barrows. Boars contained more lean in their hams than gilts or barrows and had lower back fat measurements than barrows. Although analysis of variance indicated there was no significant sex by protein interaction, the multiple regression equations of growth rate and the proportion of lean in the ham for the three sexes were significantly different from one another. The response curves based on the regression equations indicated that for optimum growth, boars and gilts required 19.6 per cent crude protein whereas barrows required only 18.4 per cent crude protein. The proportion of lean in the ham was maximized with 21 per cent crude protein for boars and 20 per cent crude protein for the gilts and barrows. There was a significant quadratic relationship between economic returns and dietary protein. The relationship was the same for boars and gilts and significantly different from that for barrows; returns were maximized at approximately the same protein level as growth rate for the three sexes. In the second experiment, 30 boars and 30 gilts were allocated to 30 treatment groups involving the two sexes, three levels of digestible energy (14.59, 15.51 and 16.22 MJ kg-1) and five levels of crude protein (18.2, 19.4, 20.6, 21.8 and 23.0 per cent). All diets were fed restrictively and pig performance was compared over the liveweight range 20 to 80 kg. Boars grew significantly faster, had a significantly lower food conversion ratio and produced leaner carcases than gilts. Increasing the DE level of the diet improved growth rate and food conversion efficiency but reduced carcase quality. Dietary protein level had no effect on any performance or carcase quality measurement.


The article presents a theoretical and an empirical research of problems of coping behavior among most at risk adolescents; it describes the interrelation between assessments of child-parental interaction and coping strategies of most at risk adolescents. The 41 teenagers from the "risk group" aged from 12 to 16, studying in 7-10 classes of different educational organizations in Irkutsk took part in this research. The "Method of primary diagnosis and identification of children from the "risk group" (M.I. Rozhkov, M.A. Kovalchuk), the questionnaire "Coping Strategies" (R. Lazarus) and the questionnaire "Parent-Child Interaction" (I.M. Markovskaya) were used in our research. The authors identified that most at risk adolescents show the coping strategies of emotional distancing from the problem situation; they rarely seek for support and understanding from parents. Ineffective child-parental interaction appears in the lack of self-control in adolescents. The obtained results made a conclusion that it is necessary to carry out the psychoeducational correctional work in order to harmonize the child-parental interrelation between most at risk adolescents and their parents, and to make constructive coping strategies and self-discipline. The article is intended for teachers-psychologists and psychologists-consultants.


This note contains a simple remark on the localization theorem in the theory of rational approximation. Let X be a compact subset of the complex plane. If a continuous function on X can be approximated uniformly in the local by rational functions, then it can be approximated uniformly on X by rational functions. This remarkable theorem, known as Bishop's localization theorem, has at least two kinds of proofs. The one is functional-analytic and depends on Bishop's splitting lemma for orthogonal measures (cf. [3; Chap. II]). Using this method, Kodama [6] was able to extend the theorem to Riemann surfaces. The other is constructive and based on the sim-

This paper assesses seismic response characteristics of seaport facilities during the 1978 Miyagi-Ken-Oki earthquake by (a) compiling and assessing documented information from post-earthquake examinations of affected facilities; and (b) using established dynamic analysis techniques to assist in this assessment. Results presented in the paper show that the most substantial damage occurred at sites of quay walls, piers, and sheet-pile bulkheads where significant liquefaction took place. The analysis showed that the site of this bulkhead structure probably experienced some liquefaction during the earthquake, and that this liquefaction could have led to the observed damage to the structure. The analysis also demonstrated that vibratory compaction soil improvement techniques would have substantially reduced the potential for liquefaction of the near-surface soil layers at this site.

Abstract : Focal-animal sampling techniques developed for investigating social behaviour of terrestrial animals were adapted for studying captive belugas, providing quantitative descriptions of social relationships among individuals. Five groups of captive belugas were observed, allowing a cross-sectional view of sociality in groups of diverse sizes and compositions. Inter-individual distances were used to quantify patterns of spatial association. A set of social behaviours for which actor and recipient could be identified was defined to characterize dyadic interactions. The mother-calf pair spent more time together, and interacted more often than adults. The calf maintained proximity with his mother; larger adults generally maintained proximity with smaller adults. Among adults, larger groups performed more kinds of behaviours and interacted at higher rates than smaller groups. Within dyads, the larger whale performed more aggressive behaviours and the smaller whale more submissive behaviours. Clear dominance relations existed in three groups with larger whales dominant to smaller whales. Vocalizations of three groups were classified subjectively, based on aural impressions and visual inspection of spectrograms but most signals appeared graded. Statistical analyses of measured acoustic features confirmed subjective impressions that vocalizations could not be classified into discrete and homogeneous categories.


ABSTRACT In this article, I investigate the long-term consequences of community civic structure on postdisaster recovery. Tracing various signs of recovery after Hurricane Katrina, I find that community civic structure is associated with deepening, rather than reducing, spatial inequality in New Orleans and report 3 findings. First, community civic structure contributes far more to repopulating communities on higher ground than low-lying neighborhoods. Second, despite the similar level of civic resources before Katrina, community civic structure has cast different impacts on reducing vulnerabilities across neighborhoods after Katrina. Though a dense civic structure helped attract more resilient populations in high-lying neighborhoods, the opposite happened in low-lying neighborhoods. Finally, community civic structure is associated with the city's racialized geography, concentrating more Whites in the city's safer areas and Black residents in the low-lying communities. These findings raise caution against pursuing community-based resilience as a postdisaster strategy.


A distributed system consists of several autonomous devices that are capable of performing certain (computational) tasks and that have a means to communicate with each other. A computer network system, such as the Internet, is a prototypical example of a distributed system. While a distributed system has many advantages over a single computational unit, e.g., the combined computational power of all entities of a distributed system typically exceeds the power of any single computational device considerably, the decentralized nature of distributed systems also poses significant challenges. In this thesis, two fundamental problems of distributed systems are studied. The first part of this thesis focuses on the problem of computing global functions that depend on the state of all devices in the system. Since each device stores only a small part of the state of the entire system, interaction between the devices is required in order compute such functions. If the bandwidth of the communication channels is bounded, it may not be an efficient solution to simply encode the state of each entity and forward this information to a single participant in the system, which could then compute the result of the function locally. Instead, the devices may attempt to aggregate the data received from other devices in the system and use this information to compute partial solutions of the global function. Such aggregation techniques may greatly reduce the bandwidth consumption when computing global functions in a distributed manner. The goal is to gain a deeper understanding of the complexity of computing global functions using in-network aggregation. In the second part of this thesis, we consider the problem that several distributed applications and protocols require that all computational devices maintain a common notion of time, but the devices do not have access to a global timer. If each device possesses its own clock, the different clock rates of these clocks necessitate the use of a clock synchronization algorithm whose purpose is to compensate for the clock drifts by exchanging timing information and adjusting the clock values according to the received information. Synchronizing clocks is a challenging task mainly due to the uncontrollable and potentially varying message delays, which render it impossible for the devices to determine how accurate the timing information is that they receive from other devices. The objective is thus to analyze the feasible degree of synchronization, which not only depends on the message delays and the clock drift rates, but also on other parameters such as the frequency of communication.


Abstract A classical link in 3-space can be represented by a Gauss paragraph encoding a link diagram in a combinatorial way. A Gauss paragraph may code not a classical link diagram, but a diagram with virtual crossings. We present a criterion and a linear algorithm detecting whether a Gauss paragraph encodes a classical link. We describe Wirtinger presentations realizable by virtual link groups.

Every year an increasing number of students with disabilities enter postsecondary education. Many of these students fail to successfully compete academically or simply leave before they complete their planned programs of study (Fairwe,llher & Shaver. 1991; Wagner. 1989). In ,1n effort to change the status quo. one community college and a university school of education program formed a collaborative support team to: • Identify and systematically eliminate barriers to postsecondary education. • Improve students' potential for having successful postsecondary experiences. "Aiming for lhe Future." the project described here, is housed in a Midwestern community collt'ge in a rural area.

Direct electronographic observations of 3C 120 with a Spectracon image converter mounted at the prime focus of the 120-inch reflector show that the bright, semistellar source is situated at the center of a smooth, elliptical nebulosity whose outer dimensions, at the level of 1.0% of sky, are 44" X 63", and whose mean color index is (B- V) = +0.85 0.15. These observations are consistent with the interpretation of N-type systems as quasi-stellar objects located at the center of elliptical galaxies. Key words: quasi-stellar objects - radio sources - N-type galaxies

The purpose of this research is to examine the moderating effect of tourists' moods on service evaluations of tour operations and overall trip satisfaction. The study used a sample of Germany tourists who traveled to the Mediterranean region of Turkey. The overall hypothesis of the paper is that tourists' assessments of service and satisfaction may not be free of bias, but may depend on the emotional state (such as mood) during the evaluation stage. The findings of the study are consistent with extant literature in the area in that a tourist's mood does influence his/her response to tour operations and overall trip satisfaction


This paper concerns the mechanical and ferroelectrical properties of TiNi/TiO2/PZT multilayers. As prototypes for `smart' materials, the TiNi and oxide ceramics must be capable of both sensing and actuation functions. For testing of the properties of these meso-scale structures to occur, the mechanical and electrical properties of the individual components need to be characterized. The mechanical properties of the PZT thin film were characterized by Scanning Electron Microscopy and optical microscopy. Cracking and defects in the PZT were observed for thick films, however thin PZT films of 1 micron or less showed better mechanical integrity. The ferroelectric properties of the PZT thin films were smaller than for bulk PZT; this was likely associated with leakage currents caused by the mechanical imperfections of the films.


An increase of mean annual air temperature (MAAT) of about 0.2‐0.48C on the Qinghai‐Tibet Plateau as compared with the 1970s, and especially winter warming, has resulted in extensive permafrost degradation. An increase of 0.1‐0.58C in the mean annual ground temperature (MAGT) has been observed. Discontinuous permafrost bodies and thawed nuclei have been widely detected. The lower altitudinal limit of permafrost has risen 40‐80 m on the Qinghai‐ Tibet Plateau. The total permafrost area on the Plateau has shrunk about 10 5 km 2 . Permafrost degradation has caused environmental deterioration, including the destabilization of buildings, impacted upon cold regions hydrology and water resources, and accelerated desertification.

SUMMARY Management of Patients With Aortic DissectionIntroduction:The incidence of acute diseases of the aorta will continueto rise as our population ages.Methods: Selective literature review.Results/Discussion:At centers specializing in maximum care,it is important that a specific strategy should be established in cases ofclinically suspected,acute aortic diseases,and non-invasive diagnosticmeasures should be taken without delay.If an acute aortic dissection is diagnosed,the necessary treatment must be provided immediately.As this disease is life-threatening,a cooperating network of referringphysicians and institutions should be set up in order to ensure optimaltreatment for these desperately ill patients.Acute type A aortic dissec-tions generally require surgery,while the primary treatment of uncompli-cated type B dissections is conservative and complicated type B dissec-tions can be treated primarily with stent-graft implantation.The referringmedical specialists and institutions should follow the patients closely after treatment so that any problems that may develop can be recogniz-ed and treated in timely fashion.Dtsch Arztebl 2008; 105(38): 639–45DOI:10.3238/arztebl.2008.0639Key words:aortic dissection,classification,diagnosis,endovascular treatment,surgical treatmentMit "e" gekennzeichnete Literatur:www.aerzteblatt.de/lit3808The English version of this article is available online:www.aerzteblatt-international.de


The silicone skeleton epoxy resin (SEP) was prepared with the chloroplatinic acid type catalyst supported natural nanotube halloysite through hydrosilylation between 1,1,3,3-tetramethyldisiloxane (TMDS) and 2,3-epoxypropylmethacrylate (GMA),and the yield of SEP was 93.26%.The morphologies of the platinum catalyst supported halloysite were characterized by SEM and TEM.The results showed that the hallysite had the clear structure of nanotube with length of 0.5-1.5μm,outer diameter and inner diameter of about 50-190 nm and 10-20 nm respectively after purificating.Moreover,after supporting on the halloysite,the platinum particles were uniformly dispersed on the halloysite surface.The chemical structure of the silicone skeleton epoxy resin was characterized by FT-IR and 1H-NMR spectra.


: Elderly is a condition where people will lose the ability of tissues to improve themselves and lose their immune power against infections that result in decreased function of muscle tissue such as the heart. The highest cause of cardiovascular disease is high cholesterol levels in the blood. One solution to deal with cholesterol problems in the elderly is by doing exercise. Poco-Poco is an aerobic exercise where the continuity of movement involves muscle groups that contract and can lower blood fat levels, so the danger of deposition of fat in blood vessel walls can be reduced. This preliminary study aimed to identify the effect of poco-poco exercise on cholesterol levels in the elderly. This research used pre-experimental method with one group pretest and posttest design to 15 elderly people in Medan. Instruments used for data retrieval are guideline and glucometer. Data analysis used was Wilcoxon test with p value 0,001 (α< 0, 05). This research indicates that there is significant effect of poco-poco exercise on cholesterol levels in elderly. Further research can apply the poco-poco exercise at least two times a week for long time period in elderly as one of alternative way in lowering cholesterol.


Historic analysis of the inflation hedging properties of stocks has produced anomalous results, with stocks often appearing to offer a perverse hedge. This has been attributed to the impact of real and monetary shocks to the economy, which influence both inflation and asset returns. It has been argued that real estate should provide a better hedge: however, empirical results have been mixed. This paper explores the relationship between commercial real estate returns and economic, fiscal and monetary factors and inflation for U.S. and U.K. markets. Comparative analysis of general equity and small capitalization stock returns is carried out with inflation divided into expected and unexpected components. The analyses are undertaken using an error correction approach. In the long run, once real and monetary variables are included, asset returns are positively linked to anticipated inflation but not to inflation shocks. Adjustment processes are, however, gradual and not within period. Real estate returns, particularly private market returns, exhibit characteristics that differ from those of stocks.


The question of a vertical refractivity gradient estimation is discussed herein. Artificial neural networks have been used as a tool to verify the existence of an unambiguous relationship between the vertical refractivity gradient and the electromagnetic wave strength measured at multiple heights by three antennas with direct visibility on the transmitter (line-of-sight links). Specific results of the estimation are presented and compared with meteorological measurements.


The oasis-desert ecotone is a special area,the process of oasis desertification or its reversion is mainly depended on the vegetation state there.The Cele oasis-desert ecotone was chosen as the study area and various parameters of Alhagi sparsifoli community were surveyed from April to October of 2009,including phenolphase observation,plant height,crown diameter,coverage,and biomass etc.Gradient wind velocity and wind-blown sand transport were conducted on the bare sand surface and Alhagi sparsifolia community ground as well and the relationships between sand transport quantity and sand drift potential were determined under the two underlayer conditions.The results show that Alhagi sparsifolia plants sprout in early April and grow up rapidly from May to July,just as aeolian sand activities come to the strongest stage in the desert regions of south Xinjiang.From August to October the plants are in a slowly growth stage and mainly carry through their lignification process,which can make the plants keep standing in whole winter.When next spring coming the dead but standing plants still have a well effect on wind block and drift sand control.Compared with the bare sand surface,wind velocity below 60 cm height in the Alhagi sparsifolia ground is decreased by 26%-67%.Total sand transport quantity on bare sand surface is 6.7 times of that on Alhagi sparsifolia community ground.According to the relationship between sand transport quantity and sand drift potential,we conclude that there are about 170.24 tons sands intruding into the oasis from its west rim per kilometer for one year,while the existence of Alhagi sparsifolia community with a coverage of 30% can block about 85% of drift sands away from the oasis.

This paper presents an overview of the RoboCup Rescue Simulation League and the rescue team FC Portugal. RoboCup Rescue Simulation is an international joint project that promotes research on distributed artificial intelligence and intelligent robotics. It offers a comprehensive urban disaster simulator, forums for technical discussions and competitive evaluation for researchers and practitioners. This paper explains the objectives of the league, the mechanics of the simulator system and the main challenges in the research conducting using RoboCup Rescue simulator. In this urban disaster simulator, heterogeneous teams of agents try to minimize damage to both people and urban property after the occurrence of an earthquake. The city is filled with burning buildings, trapped civilians, and blocked roads. Teams of simulated fire brigades, policeman and ambulances collaborate in order to face the disaster. In this context, an overview of FC Portugal's rescue team is presented, including the strategic coordination layer of heterogeneous agents and implemented agent's roles and sub-tactics. In order to show the research conducted using the Rescue simulator some of the most interesting league problems are discussed together with FC Portugal's solutions. Results achieved in international competitions are also briefly presented, with emphasis on the 2006 European championship in Eindhoven, which FC Portugal won.


Abstract Four-degree-vertices-type diagrams are the most frequently used in solid-state and statistical physics. These are applicable in the following fields: (i) standard perturbation expansion of the Green functions; (ii) variational description of models with local interaction; (iii) Hugenholtz-type diagrams for two-body potentials; (iv) renormalization group; (v) standard Φ4 theory, including four point and two point functions, which is applied to localized spin systems, amplitude functions and expansions; (vi) exact solution of the non-interacting, two-dimensional (sixteen, thirty-two, one hundred and twenty-eight) vertex models. We present the complete topology of the four-degree-vertices diagrams up to eighth order, in a condensed manner, characterizing a total number of contributing graphs of order 109, and we determine the topologically different contributions for every order. The result is a simplification in calculating the contributions of the different orders, e.g. in eighth order instead of ...


Next-generation wireless network systems are foreseen to provide high peak spectral efficiencies (as much as 15 bps/Hz in the downlink and 6.75 bps/Hz in the uplink under ideal conditions) and high mobility (up to 120km/h). Due to such demanding requirements, the need for efficient MIMO signalling schemes and corresponding efficient receiver architectures becomes mandatory. In this work, we investigate a number of alternative full-rate MIMO transmission schemes with different receiver structures. Beyond a brief description of the proposed schemes, simulation results are presented, where the test parameters and the performance requirements are chosen, whenever possible, in compliance with the IEEE 802.16m Evaluation Methodology Document (EMD). Such simulation results assess the performance of the proposed schemes in a WiMAX scenario and allow comparing the different solutions on a foot of parity.


Recent research has claimed that American private high schools are more effective than public high schools. Two critical aspects of this research are at the center of this article: a) whether the short-term benefits of private schools which were found to exist persist over an extended period of time; b) whether these effects can be explained by differences in funding. In the Netherlands public and private education are equally funded. Longitudinal data on the educational attainment of the 1965-cohort during the whole of their secondary education were used to establish whether Dutch Catholic, Protestant and public secondary schools have differential effects on their pupils' educational achievement. The results of the study demonstrate the presence of a school sector effect in the Netherlands on the educational attainment of their pupils.


The utilization of a diagnosis method of the farm influence on the environment is quite opportune in the present context: (i) The environment is a strong component of agricultural policies and a diagnosis is needed to guide the implementation actions (agro-environmental measures, CAP subsidies, high value environmental certification, recognition of high natural value agricultural systems, conversion to organic farming, etc.); (ii) The impact of production techniques upon the environment becomes increasingly necessary to be evaluated along the quality product chains. The purpose of the method is to establish the current environment condition at a given moment, to put into evidence the ecological systems, to identify the risky practices and to suggest improvement modalities to farmers. At the same time, the diagnosis has the capacity to evaluate: (i) "the value added" of the environment, through a better nitrogen and organic fertilizers management; (ii) own natural resources (soil, weather, biodiversity, etc.); (iii) pressure upon water and energy, etc.; (iv) negative and positive effects upon the local eco-systems. The method has a double approach: a global one – analysis of the farm system and its practices (30 indicators, on a scale of 1 to 100 scores) and a thematic one – impact of the farming activity upon the different environment compartments (23 indicators, from 1 to 20 scores). The "DIALECT" method used for the agro-environmental diagnosis on a crop production farm yielded interesting results, specific to the Romanian agriculture, and certain indicators were comparable to the environmental indicators of similar groups of European agricultural holdings.


An ensemble of hard-core particles with infinite-range cosine interaction is solved exactly in one dimension. The system exhibits a disordered (high-temperature) and a periodically ordered (low-temperature) state, a classical second-order (high-density) and a first-order (low-density) phase transition, and four regions in the activity-temperature plane.


The COVID-19 pandemic highlighted an urgent need for reliable diagnostic tools to minimize viral spreading. It is mandatory to avoid cross-contamination between patients and detect COVID-19 positive individuals to cluster people by prognosis and manage the emergency department's resources. Fondazione IRCCS Policlinico San Matteo Hospital's Emergency Department (ED) of Pavia let us evaluate the exploitation of machine learning algorithms on a clinical dataset gathered from laboratory-confirmed rRT-PCR test patients, collected from 1 March to 30 June 2020. Physicians examined routine blood tests, clinical history, symptoms, arterial blood gas (ABG) analysis, and lung ultrasound quantitative examination. We developed two diagnostic tools for COVID-19 detection and oxygen therapy prediction, namely, the need for ventilation support due to lung involvement. We obtained promising classification results with F1 score levels meeting 92%, and we also engineered a user-friendly interface for healthcare providers during daily screening operations. This research proved machine learning models as a potential screening methodology during contingency times.


Ground effect on hovering rotor performance has been widely studied both experimentally and theoretically, yet most applications have focused on global thrust and power values. Motivated by the Sikorsky Human Powered Helicopter Challenge (HPH), an attempt to further study ground influence on a hovering rotor of highly elastic blades in extreme ground proximity has been carried out. The experimental portion of this study includes both a rigid blade sub-scale set-up and elastic blade full scale set-up. Experimental results are used to validate a new computational tool that couples rigid prescribed wake, blade element aerodynamics and finite-element structural modeling, tailored together for prediction of elastic blade behavior in ground effect. The current model accounts for local height off the ground at each blade element, and allows for more detailed insight regarding angle of attack, induced velocities and lift distributions along the blade in extreme ground effect conditions.


Exposure of human umbilical vein endothelial cells to oxidants such as hydrogen peroxide, tert-butyl hydroperoxide and diamide has been shown to induce oxidant-specific S-thiolation of cellular proteins with glutathione. In this study we show that the diamide-induced S-thiolation of a 42 KDa protein is accompanied by cell shrinkage and the loss of cell to cell contact due to a structural reorganization of the cytoskeleton, as assessed by cytofluorometric visualization by confocal microscopy. Both events are simultaneously and rapidly reversed upon the removal of the stimulus. The 42 KDa protein was identified as actin by sequence analysis of the excised and electro-blotted protein band from SDS-PAGE gels, by immunochemical detection and by binding to immobilized deoxyribonuclease I. Additionally, we have shown that diamide exposure of the cells resulted in a S-thiolation of both polymerized F-actin and monomeric G-actin.


Using the katharometer, and adopting the two bulb method, it was possible to study the variation of the thermal diffusion ratio kT and the thermal separation ratio RT with temperature over the range 30-1165°K. The results obtained indicate that the thermal separation ratio J?T increases with increasing temperature. The variation of Rr occurs within a limited range of temperature. The experimental results were compared with those previously obtained. Also the experimental values of RT obtained were compared with the theoretical ones to find suitable force indices. Introduction Experimental confirmation of the theory of thermal diffusion in gases has been carried out by CHAPMAN and DOOTSON [1] , IBBS, GREW and HIRST [ 2 ] have studied the variation of thermal separation with temperature on some gas mixtures. In case of H2—N2 mixture measured at low temperatures down to that of liquid air, it was shown that the thermal separation was proportional to Iog10 TIIT2 until the cold side reaches about — 1 0 0 ° C . This proportionality means that kT was constant over this range of temperature. At lower temperatures the proportionality no longer holds and the separation falls below its ordinary value. The constant value of kT observed over a limited range of temperature suggests that the molecules might be regarded as point centres of repulsive forces. The falling off in the value of kT at the lower temperatures might be due to a change in the nature of the collisions as the temperature was reduced. LUGG [3] has used a mixture of H 2—C0 2 containing 46-8% of C 0 2 . The graph of the thermal separation obtained showed two different slopes, the point of intersection of the two lines gave the temperature at which kT changes as 204°C, i.e., there was one value of kr below 204°C and another greater value above it. The present work investigates the variation of the thermal diffusion ratio kT and the thermal separation ratio RT with temperature for the binary gas mixture H2—N2 in the temperature range 30-1165°K. 1 N.

Abstract This study aims to examine the influence of consumer engagement with Super Bowl ad tweets, on their engagement with the advertiser's official Twitter account. Using Python, audience engagement data were collected from the Super Bowl advertisers' official Twitter accounts on a daily basis from two days before the game until 10 days after the game; this procedure resulted in 351 cases for 27 advertisers in a balanced panel dataset. Overall, the results of panel regression analyses employing a feasible generalized least squares (FGLS) procedure and panel-corrected standard error (PCSE) estimates support the hypothesis predicting transference of engagement from Super Bowl ads tweets to the advertisers' official Twitter accounts. In particular, of the three engagement metrics, the number of retweets of and favorites on the Super Bowl ad tweets significantly increased the numbers of followers and favorites on the official Twitter accounts of the Super Bowl advertisers. The theoretical and managerial implications of the findings are discussed.


Pyridazine derivatives represent one of the most active classes of compounds possessing a wide spectrum of biological activity. They are widely used in pharmaceuticals and agrochemicals. In view of these facts and in continuation of our interest in the chemistry of pyridazines, pyridazinones are six membered cyclic 1,2-diazine having carbonyl group at 3-position of ring system. They are widely used for industrial purposes and also exhibit a broad range of biological activities. This short review compiles examples of the most promising antibacterial activity. An overview on the antifungal activity is also described.


Bordetella bronchiseptica causes severe respiratory disease in guinea pigs and it has been associated with stillbirths, abortions, infertility and infections of the reproductive system and tympanic bullae. Disease caused by Bordetella bronchiseptica in pet guinea pigs is mostly a poor understood disease; studies about this pathogen has been conducted mostly in laboratory guinea pigs. The objective of this review is to condense published information about the disease caused by Bordetella bronchiseptica in guinea pigs for the veterinarian who attends pet guinea pigs, with special emphasis on the prevention of this disease. The author concludes that vaccination in pet guinea pigs against Bordetella bronchiseptica needs to be considered for future studies.

This paper reports the results of evaluating a large sample of the 23,858 type-10 homographs found in Roget's International Thesaurus (3rd Ed.) as defined by the Bryan Model of abstract thesauri, of which Roget's is an instantiation. According to the Bryan model, two different entries in a thesaurus that have the same spelling are homographs (semantically unrelated) if and only if they cannot be the endpoints of a sequence of entries called a type-10 chain. The Bryan definition of a type-10 homograph has not been tested thoroughly until recently because of the combinatorial complexity associated with a direct application of the definition to a large instantiation such as Roget's. However, in 1989, the authors were able to decompose Roget's in into its type-10 components, and as a result, generate all 23,858 type-10 homographs at the semi-colon category level.
The principal result is that Bryan's definition of homographs by type-10 semantic disjunction does not appear to work uniformly over a broad range of entries in Roget's when the selected semantic category is the semi-colon group. Although there are many cases where type-10 homographs agree with conventional classifications, in general type-10 discrimination at the semi-colon level "over discriminates" in that it generates many more homographs than are found in standard English language dictionaries.


EFFECT OF REDUCED RATES OF SPINOSAD AND BACILLUS THURINGIENSIS ON BELL PEPPER PESTS AND BENEFICIAL ARTHROPODS, 1999: This test was conducted to evaluate reduced rates of spinosad and Bacillus thuringiensis as economical, pest-selective alternatives to broadspectrum insecticides for a pepper IPM program in the Northeast. 'Boynton Bell' peppers were transplanted into a field at a commercial farm in Enfield, Connecticut on 26 May. Weeds were controlled by regular hand and mechanical cultivation. Each plot consisted of 50 plants in 5 rows, 15 ft long, with 1.5 ft between plants and 3.5 ft between rows. Three treatments were replicated four times in a RCBD. Treatments consisted of four applications of spinosad (SpinTor 2SC) at 4.0 oz/acre or Bacillus thuringiensis (Mattch) at 6.0 pt/acre on 4, 11, 18, and 25 Aug, and an unsprayed check. Triton b-1956 Spreader Sticker (4 oz per acre) was applied with each insecticide application. The application on 11 Aug was followed by heavy rain approximately 20 min later and was not reapplied. Plants were sprayed from the top and sides with a CO2 backpack sprayer at 50 psi with 40 gallons of water per acre. Aphid and beneficial arthropod populations were counted on three plants per plot on 25 Aug. Beneficial arthropods sampled included: ladybird beetles, lacewings, midge larvae, syrphid fly larvae, stink bugs, spiders and wasp-parasitized aphids. The first 50 large and extra-large fruits encountered were harvested from each plot on 1 Sep. The fruits were dissected and the number of ECB larvae and infested pods were counted. Data were analyzed using ANOVA and Tukey's HSD.

A vacuum cup with adjustable water temperature relates to a structurally-improved vacuum cup, which can satisfy different drinking requirements of various populations. The vacuum cup comprises a cup body and a cup lid, and the structural key point thereof lies in that a partition board is arranged in the cup body, a hot water cavity with a hot water outlet and a cold water cavity with a cold water outlet are respectively formed on two sides of the partition board, a circumferential chute distributed along the inner wall of the cup body is formed at the upper end of the cup body, and a slip sheet with a slider is arranged in the circumferential chute.


The giant drug company Pfizer is conducting a "virtual" clinical trial that relies solely on electronic rather than face to face encounters between researchers and participants. It announced the trial on 7 June at a conference on clinical trials held on the Bethesda, Maryland, campus of the US National Institutes of Health.

Freda Lewis-Hall, Pfizer's chief medical officer, said that the company is trying to reduce barriers to participation in clinical trials; to offer a consistently strong experience that does not vary by location; and potentially to save money in conducting trials in the future, if the concept proves viable.

Surveys of patients show that the …

Fault in the power distribution system causes protection system tripped and the electrical supply disturbed. The electrical fault occurred by lightning, strong wind, wood cutting, then the aging and an inadequate network component maintenance. It certainly leads to the poor power quality and voltage sag as well. An assessment power quality is an essential thing for utility and the energy supplier to identify and fix a critical area up. The fault location program has an important role in short-term planning operation of electric distribution network to reduce downtime and improve system reliability. A network modelling and faults simulation has been done to obtain voltage sag and current information. Then, the voltage sag at measurement point will be purposed to identify and classify a fault by using K-Means Clustering. Fault location estimation used by technician to repair electrical supply in real system, Kupang substation.


The morphology of dry and hydrated perfluorosulfonic acid (PFSA) ionomers at cryo and room temperature is examined using TEM/STEM with EELS capability. Z-contrast imaging was utilized to identify the micro-phase separation of the hydrophilic side chains containing water and the hydrophobic polytetrafluoroethylene (PTFE) backbones. The results compare very favourably with hydrated morphologies obtained through mesoscale dissipative particle dynamics (DPD) simulations. The cryo-STEM images of plunge-frozen samples was also found to agree with morphologies based on SAXS experiments.


BACKGROUND
Liver stemness refers to the highly regenerative capacity of the organ. This intrinsic regeneration capacity allows the restoration of post-resection liver function in up to 50% of liver donor. Liver cirrhosis is one of the terminal liver diseases with a defect in the intrinsic regeneration capacity. Several attempts to restore intrinsic regeneration capacity from in vivo studies of stem cells in various organs have shown the positive impact of fasting on stemness. There is an increased capacity for stem cell proliferation and regeneration due to fasting. Prolonged fasting (PF) has been reported to maintain the long-term proliferative ability of hematopoietic stem cells. However, clinical trials on intermittent fasting (IF) have not conclusively given positive results for fasting individuals.

OBJECTIVES
This research aims to investigate the effect of fasting on liver stemness by comparing the expression of octamer-binding transcription factor 4 (Oct-4), cytokeratin 19 (CK-19) and peroxisome proliferator-activated receptor γ co-activator α (PGC-1α) in liver cells of fasted rabbits with rabbits fed ad libitum. This study compares two types of fasting which are intermittent (16 hours) and prolonged (40 hours) fasting for liver stemness and intrinsic regenerative capacity.

METHODS
18 rabbits were conditioned into 3 different groups. The first group was subjected to ad libitum diet, second to intermittent fasting (16-hour fasting), and third to prolonged fasting (40-hour fasting). Afterward, the RNA was extracted from the liver tissues of each rabbit and analyzed via real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). Relative expression was calculated using the Livak method.

RESULTS
In comparison to the ad libitum diet, there were higher increase in PGC-1α, upregulated Oct4 and steady CK-19 gene expressions in the liver of intermittent fasting liver. Prolonged fasting increased PGC1α, reduced liver stemness, and a statistically insignificant decrease of intrinsic liver regenerative capacity.

CONCLUSION
Intermittent fasting indicates preferable molecular alterations in liver stemness and intrinsic regenerative capacity compared to prolonged fasting.


Abstract One of the challenges is to know the exact value of magnetic field in a three-dimensional space which is unknown so far. In this paper we have used integration formula in a Mathematica software to calculate the exact magnetic field and then set up an experimental method to verify this experimentally by applying a magnetic field with a physical magnet of the diameter of 8.1 cm and height of 6 cm. Finally, a comparison between theoretical and experimental calculations is shown in two-dimensional and three-dimensional graphs.We develop a theoretical model by using Mathematica software to calculate the magnetic field for a one-sided magnet using a single electromagnetic coil and several electromagnetic coils. Similarly, we have developed a method to calculate the magnetic field using Mathematica software when two electromagnets are set on both sides of the arc plasma for a single coil and several coils. In all cases, theoretical data is verified by the experimental value. By comparing the graph for both one-sided and two-sided coils we have found a good agreement between the data with the experimental and theoretical values.


I. WHAT IS HYPNOTISM? In presenting this topic of hypnotism for discussion, I have thought it opportune to reconsider the subject, notwithstanding all that has been written about it, for in my judgment more superficial, unscientific observations have been made, more specifically selected data to bolster up particular hypotheses have been collected, more ill considered conclusions have been drawn, and more nonsense has been written than in any other important problem. The terms hypnotism and hypnosis have acquired unfortunate implications and connotations and are not free from stigma and prejudice even in the minds of physicians. In the minds of lay people, they border on the occult. Furthermore, they do not correctly define the phenomena. Some new and more correct term is therefore desirable—one that will represent the psychophysiologic principles involved and will be descriptive of the phenomena. For there is a general misunderstanding of the nature of hypnosis, leading

— Clusters of Microcalcifications (MCCs) are most frequent symptoms of Ductal Carcinoma in Situ (DCIS) recognized by mammography. Least-Square Support Vector Machine (LS-SVM) is a variant of the standard SVM. In the paper, LS-SVM is proposed as a classifier for classifying MCCs as benign or malignant based on relevant extracted features from enhanced mammogram. To establish the credibility of LS-SVM classifier for classifying MCCs, a comparative evaluation of the relative performance of LS-SVM classifier for different kernel functions is made. For comparative evaluation, confusion matrix and ROC analysis are used. Experiments are performed on data extracted from mammogram images of DDSM database. A total of 380 suspicious areas are collected, which contain 235 malignant and 145 benign samples, from mammogram images of DDSM database. A set of 50 features is calculated for each suspicious area. After this, an optimal subset of 23 most suitable features is selected from 50 features by Particle Swarm Optimization (PSO). The results of proposed study are quite promising.

Background:Traditional statistics in longitudinal data analysis are likely to be insufficient in nursing studies, in which the time varying characteristics of explanatory variables and cumulative effects require additional consideration. Objectives:The aims of this study were to introduce alternative longitudinal approaches for incorporating time-varying variables and cumulative effects, to discuss their strengths, and to highlight key issues that nursing researchers should recognize before and while undertaking such analyses. Results:The three alternative models provide differing analytical outcomes based on the research focus. The baseline tracking model was used to estimate the stability effect of an intervention program, detecting risk factors early. The temporal sequence of potential cause and effect was incorporated further in the time-dependent model. The cumulative model was used to explore whether cumulative intervention effects existed. Conclusion:Nurse researchers should incorporate alternative methods into the longitudinal data analysis tools they commonly use when facing explanatory variables with time variations or cumulative effects on the variable being measured.


The real opportunities for volume growth in the global beer market no longer lie in the markets most of us have worked in for many years - North America and Europe. China, South East Asia, India and Central and South America are the areas of growth being looked at, and I promise this is the final piece of advertising, Canadean now offers reports on all of these areas. I have been asked to talk about growth opportunities in Central South America: I have divided the presentation into two: Firstly, I will look at the market in context of the global beer market, volume trends, per capitas and trends in the key markets. Then I will look at two key issues; the expansion of local players into regional players and, secondly, the level of international involvement that now exists in South America.


On-demand routing protocol is very popular in multi-hop mobile ad hoc network(MANET) for its low overhead,but vulnerable to malicious attacks for lack of secure mechanism.The advantages and drawbacks of the current secure enhancement method based on the DSR are analyzed.A new secure enhancement method based on an efficient Elliptical Curve Cryptosystem(ECC) digital signature using backward authentication is proposed for DSR protocol Sec-DSR,which has be proved secure and efficient theoretically.By using the blackhole and rushing attack model,Sec-DSR is simulated on the QualNet simulation tools.The results show that the proposed secure protocol can obtain stronger security without sacrificing large overhead.


The rapid growth of web-based instruction has raised many questions about the quality of online courses. It appears that many online courses are simply modeled after traditional forms of instruction instead of incorporating a design that takes advantage of the unique capabilities of web-based learning environments. The authors present a conceptual framework that can guide the development of online courses. Specific examples of instructional strategies that fit the framework are described in detail.


Mobile objects and agents are used for implementing distributed applications. Both concepts allow efficient use of local resources, volatile network connectivity and more efficient communication due to appropriate migration, especially in dynamic ubiquitous environments. Mobile processes enable specifying the complete life cycle of complex mobile applications.
 In this paper, we propose a mobile-process-based platform that turns ubiquitous application development into a manageable task. We advocate the use of Web services for implementing mobile processes in a heterogeneous environment. Based on previous work, we sketch a novel approach for realising mobile context-aware Web services, which implement process steps. We use a separation of state, functionality and implementation code, which enables a reduction, expansion and transformation of the service state and functionality during migration.


Models can help scientists study and understand phenomena. Such models need to be informed by theory. We report on the early stages of our ongoing study in which we use interactive visualisation to help improve the construction of theory-driven models, by facilitating the exploration of statistical summaries of input variables, compare the quality of alternative models and keep track of the model-building process. Later work will investigate whether machine-learning techniques can be incorporated without compromising the models' theoretical bases.


ABSTRACT This article examines the way a group of Latina girls responded to instances of sexual harassment in a public high school in Madrid (Spain). I begin with a current event: educational reforms seeking to address the 'problem' of youth democratic disengagement. Drawing on ethnographic and genealogical modes of inquiry, I examine the subjective capacities (technologies of the body) that were being developed by these girls in the attempt to respond to instances of sexual harassment—silencing and under-sexualizing their bodies. This study steps back from any straightforward truth-claim about education, citizenship, and responsibility in democratic societies in favour of taking a longer view of how citizens are produced within its situated democratic culture—here, regime of conviviality. This article concludes that these girls' bodily response to instances of sexual harassment in school cannot be dissociated from the historical production of the logics of conviviality that grounds this educational reform, where dissent is displaced from democratic culture. Ultimately, this article transcends notions of the political in human agency that parallels responsible citizenship with resisting social norms to conclude that notions of the political in human agency cannot be dislocated from the historically contingent discursive traditions in which they are located.


The terms social politics and Islamic law have closely correlated meanings, which strongly support each other and even inseparable. This paper will discuss the influence of social politics development along the formation of Islamic law. Research questions to be addressed are: what is the nature of politics and power in Islam?, to what extent is the political influence on the development of Islamic law?, and what is the social history of the establishment of Islamic law? This research has a development characteristic and applies a socio-historical approach. The result indicates that the essence of politics and power is everything that leads to how to manage and organize governance in a country for the benefit of its nation on the principles of justice. With regards to political influence on the development of Islamic law, it significantly depends on the circumstances that exist in every decade.  As for the social history of the Islamic law establishment, it is divided into six phases, beginning with the phase in which everything is referred directly to the Prophet, to end up in the last phase, which is the phase of taqlid (blindly following earlier opinions from priests).


Since the end of the Cold War, many if not all, European or Western countries have increasingly used their armed forces for missions within the borders of the state. The aim of this article is to compare the internal deployment of the military in two European countries: Germany and Italy, both of which experienced authoritarian rule and militarism in the 20th century. However, despite similar historical experiences, there have been considerable differences between the two countries in terms of the roles their armed forces have come to play in addressing domestic challenges in recent years. Indeed, they may represent opposite extremes on a spectrum ranging from very limited to very farreaching involvement of military forces in internal (security) matters.


One of the components of the environment that determines the success of plant cultivation is climate. To predict rainfall, the author uses the ARIMA Box Jenkins method, which is a quantitative forecasting method. The data used are data for the period July 2012 to June 2017. In this study, the right model is the ARIMA model (2,0,2) with Xt = 4.05668 + 0.9416Xt-1 - 1.0039Xt-2 - 0, 8558et-1 + 0.9617et-2 + et which is used to forecast rainfall for the next 12 periods. The selection is based on the smallest MSE (average error squared) value of 0.033401954 and the smallest RMSE (root mean square error value), which is 0.001115691 and the smallest MAPE (absolute average error percentage) is -0 , 00801773.


It is a problem for thyristor trigger to adapt automatically the variation in a wide frequency band of the input power.This paper analyzes the reason and gives the solution to track the variation of the input power frequency with a high accuracy F/V.The output of the high accuracy F/V can be the input of a power device with constant current which can be the input of the sawtooth trigger.Thus.The frequency variation of the sawtooth trigger with that of frequency of the input power can be tracked,while the amplitude of sawtooth keep constant.Consequently,in the case of same phase-shifted voltage,the triggering angle of the thyristor is independent of the variation of input power frequency in a wide range.Trigger pulse can be resulted from the combination of a double time base chip 556 and a comparator.Then a 3-phase-shifted thyristor trigger can be obtained to track input power frequency variation in the rage of 30~160Hz.Excellent results were obtained in the application to several rectifier thyristor devices with high power.


The purpose of the present investigation was to observe simultaneous laryngeal and respiratory function during singing. Five professionally trained classical singers (three men and two women) performed singing tasks including crescendo–decrescendo at two register transitions. Laryngeal aerodynamic measures of estimated subglottal pressure, open quotient, speed quotient, maximum flow declination rate, and alternating glottal airflow were made as well as acoustic measures of sound‐pressure level and fundamental frequency. Lung, rib cage, and abdominal volume measures were also made for each breath group. Aerodynamic data were collected with a Glottal Enterprises airflow mask. Oral airflow was inverse‐filtered using CSpeech. Respiratory data were collected using Respitrace. Aerodynamic, acoustic, and respiratory kinematic data were used to describe the respiratory and laryngeal mechanisms used to control register transitions. Individual subject data show respiratory and laryngeal variation when comparing reg...


The dilithium derivatives of the ditertiary 1,2-diols, cis- and trans-1,2-dimethyl-1,2-cyclo-hexanediol, fail to undergo base-induced stereochemical equilibration under conditions that lead to such equilibration with the dilithium derivatives of the disecondary 1,2-diols, cis- and trans-1,2-cyclohexanediol. This casts doubt on the proposal that the latter equilibration proceeds by carbon–carbon bond cleavage of the dialkoxide to give a diketyl intermediate. It is highly probable that it involves oxidation–reduction as established by Doering in the case of monohydric alcohols. Examination of steroidal secondary-tertiary 1,2-diols under similar conditions shows that such systems can epimerize at both carbinol centres; this is interpreted in terms of sequential oxidation, α-ketol rearrangement, and reduction.


On the basis of absorbing the accumulated ruling experience in histroy and proceeding from the general objective to build socialism with Chinese characters, the third generation of leadership group of CPC with President Jiang Zemin at its core put forward for the first time the philosophy of Rule by Virtue, and combines the philosophy with"Govern the Country with Law" as the general plan to govern the country. The philosophy of Rule by Virture is actually the extension and development of Marxism, Mao Zedong Thought and Deng Xiaoping Theory, which is of guiding significance to the great practice of building socialism with Chinese characters. Higher learning institutions bear the important mission to train and cultivate the successors to the cause of socialism. University students are today the masters of the campus civilizations, and will be tomorrow's pioneers of the community civilizations. Only when moral education of college students is strengthened can the philosophy of Rule by Virture really strike root in the hearts of people and the quality of the citizens be really improved.


The success of implantable technologies to generate advancements in biorobotics or neuroprosthetics hinges on the development of a multichannel electrode array capable of one or two way communication with a large number of neurons at high channel fidelity over very long implant durations. While a large number of conductive materials have been developed as candidate materials for a long-term neural interface, very few meet the strict requirements of the unique bio-chemical-mechanical environment of the brain. In particular, one of the common shortfalls seems to be in the inflexible materials often chosen for such devices, despite the common knowledge that the brain itself is a very 'soft' viscoelastic environment. In an effort to improve long-term performance of cortical implants, we present a design-based strategy that includes finite-element modeling of a mechanically flexible tissue/device interface


The most recent realization of the ITRS, the ITRF2014, will account for non-tidal atmospheric loading corrections applied at the normal equation or the parameter (solution) level. In its function as one of the three contributing ITRS Combination Centers, DGFI-TUM investigates the methodology to apply these corrections at the normal equation level. In this paper, the derived procedure is presented in detail and the following four global SLR-only TRF solutions are compared with each other:


We report a power law derived from experimental atomic force microscopy (AFM) data suggesting a nano to mesoscale transition in force-distance dependencies. Our results are in relative agreement with the Hamaker and Lifshitz theories for van der Waals forces for the larger tip radii only.


The coda synthesizes a number of the concerns raised over the course of the preceding chapters. It focuses special attention on the vexed status of difference as a philosophical and political concept within English studies over the last several decades. The coda concludes by offering some potential points of tension in the discipline in the coming years.


In recent years, the usage of smart phones has increased tremendously. These devices are enough capable to support high number of intensive applications which results shorten power and limited performance. Cloud Computing can augment the computing capabilities of smart mobile phones by computational offloading. In the case of low bandwidth conditions, migration of complex and large data on cloud takes more energy and time than processing data on mobile devices. In this paper, an energy efficient task offloading algorithm is proposed to achieve the energy-efficiency for mobile application in the cloud assisted environment. The proposed offloading algorithm is used to determine what kind of tasks should be chosen to migrate on cloud. The result shows that the proposed algorithm can achieve efficiency upto 93.2 % for execution time and 97.6 % for energy.

Pearson correlation analysis obtained the value of r = 0.922, which means that there was significant correlation between the concentrations of neem seed extract against mosquito larvae mortality of third instar Culex sp. Key word s : neem seed extract (Azadirachtaindica); mortality; Culex sp.


Herein, the photoelectrocatalytic and photocharging activity of a Ni3TeO6 (NTO‐700) photoelectrocatalyst for water oxidation in alkaline medium is demonstrated and calcined at 700 °C. The photoelectrocatalytic (PEC) activity of the sample is increased upon an increase in the illumination time. With a twofold increase in photocurrent density at 1.8 V, the PEC 150 sample (having been illuminated for 150 min) attained the highest PEC activity. The synthesized material has displayed an excellent charge storage capacity in KOH and Na2SO4 electrolyte solutions (both 0.1 m). The chrono‐amperometry measurement, subsequent to light interruption, has sustained almost 44% higher current density (even after 200 min) compared to the pure electrocatalytic baseline in a Na2SO4 electrolyte. The charge transfer resistance, Rct, decreases from 633.40 to 170.40 Ω, while the charge transfer rate constant, kct, increases from 7.93 to 27.03 s−1, as a function of illumination time. This points to fast separation of electron–hole (e−–h+) pairs and a slower recombination rate. The lower values of the charge transfer resistance and the time constant recorded for the light interrupted samples, as compared to the electrochemical sample, are attributed to the stored charge that drives water oxidation at a higher rate.


The ability of people with HIV infection to acquire health insurance varies tremendously from state to state, from jurisdiction to jurisdiction within states, and from job to job within the workplace. In far too many situations, insurance is either completely unavailable or prohibitively expensive. When it is available, it often includes draconian limitations on pre-existing conditions and important benefits like prescription drugs, mental health care, home care or hospice. President Clinton's Health Security Act makes significant progress in dealing with most of these problems. Most importantly, it would eliminate all pre-existing condition exclusions: no one could be denied insurance, or charged a higher premium, because they had any illness prior to coverage. It would also eliminate lifetime maximums, which in recent years have affected hemophiliacs with HIV disease who must spend up to $15,000 every two months for blood products, and would cover prescription drugs and mental health services. The plan is not perfect. Some critics say it does not go far enough in reforming the current confusion of public and private programs with different eligibility criterion, widely varying benefit packages, and exclusionary rate structures. Others say it goes too far—raising the battle cry of "socialized medicine." Between the two extremes are a large number of people who believe the Health Security Act is a thoughtful, comprehensive, and equitable effort to extend health care coverage to all Americans. For the vast majority of people with HIV disease who have private insurance, the comprehensive benefits package in the Health Security Act would be comparable to—or richer than—the benefits they have now. For those receiving coverage under Medicaid or other public programs, the package would be a significant improvement. And for those with no coverage at all, the plan eliminates a major source of stress and anxiety in their lives, ensures adequate treatment, and protects against financial ruin.


The study sought to analyze the influence of inventory management on organizational performance . The study sought to achieve the following specific objectives: to assess the influence of inventory investment on organizational performance and to explore the influence of inventory turnover on organizational performance. This research adopted a descriptive approach on inventory management effect on organizational performance in the energy sector in Kenya. The target population of this study was composed of the management staff of Kenya Power . Simple random sampling technique was applied to come up with a sample size where primary data was gathered directly from respondents and for this study the researcher used a questionnaire. The questionnaire consisted of close and open-ended questions. The researcher conducted a multiple regression analysis so as to determine the relationship between inventory management and organizational performance. The target population was 300 staff management. The researcher used stratified random sampling procedure to select a sample size of 90 respondents. Quantitative data was collected using questionnaires and analyzed by the use of descriptive statistics using SPSS . From the findings, the researcher recommended that strong policies should be implemented in in the energy sector for them to do away with the problem of organizational non-performance. To curb various challenges of inventory shrinkage in the organization, the energy sector should consider implementation of a vendor managed inventory to lower incidences of stock-out situations. The inventory investment for any organization should be spelled out as part of the organization terms. The institutions should put up to date information technology systems which are easy to follow for both the employees and the borrower, and so as to avoid carrying of excess inventory that might be a risk to the Company, accurate forecast should be in place. Key Words: inventory investment, inventory turnover, Energy Sector in Kenya


In this paper we seek to expand and understand the complexity and richness of labour. This concept takes a double an opposite determination for Marx: as alienated labour and as free activity, creative, voluntary and rational. To do this, we will show that, discuss about labour is the same as arguing about the man himself. This concept is understood as hermeneutic exercise of comprehension that man makes about the world, about himself, and about others. Therefore, the fight against all possible alienation or oppression is but the commitment to build another world, a different one, and that world is no more than communism. The complexity with this concept and the reality, that is labour, reveals the inability to understand human being. Work is where oppression is generated but at the same time, is the place from where you can make the radical transformation of both, the objective and subjective conditions that underpin the building of political economy on which it stands and is where can reverse the alienation. The methodology that we used for this paper will consist on the bibliographical analysis of Marx's work, centering as a priority on two texts; one of his writings of youth, known as los Economic and Philosophic Manuscripts of 1844 (2001). The other text is the most famous one, written in his last years of life, known as Capital (2000). We are going to analyze, in these two writings, the role and the place which plays labour as access key to an oppressive economic system. Likewise, there will be a critical reading on the bibliography of some  interpreters of Marx; some of them are Marxists, other ones critics and most of them in an intermediate situation. The purpose of this, is to expand the horizon of study in other to give birth to the impact and the reception that this problem has had on philosophers and thinkers throughout history. Just to mention a few: Arendt, Del Barco, Derrida, Sartre, Fromm, Lukacs, Marcuse, Balibar and Negri.


Flexoelectricity is a property of all dielectric materials in which they polarize in response to deformation gradients such as those produced by pressing, bending, or twisting, and knowledge of flexoelectric coefficients is essential when considering the applications of flexoelectricity. Here, we describe an experimental approach to the measurement of cylindrical flexoelectric coefficients of polyvinylidene fluoride. Two specimens are designed to generate and decouple the corresponding strain gradients. Theoretical and finite element analyses are developed and simplified, and specimen designs are then tested to obtain multiple strain-gradient-coupled electric polarization charges. The flexoelectric coefficients μφzρρ and μφzzρ are then decoupled, using two independent equations together with the experimental data. This work provides an experimental method that can be used to obtain multiple unknown flexoelectric coefficient tensor components by imposition of a twisting load, and it reveals the potential for the application of flexoelectricity in irregular structures in complex environments.Flexoelectricity is a property of all dielectric materials in which they polarize in response to deformation gradients such as those produced by pressing, bending, or twisting, and knowledge of flexoelectric coefficients is essential when considering the applications of flexoelectricity.

A serious adverse reaction of valproic acid (VPA), a widely used anti-epileptic, is a rare but potentially fatal hepatotoxicity affecting mostly children under 2 years of age with developmental delay and who are on V P A polytherapy. The mechanism of the hepatotoxicity remains unknown. This thesis describes in vivo and in vitro studies to examine the hypothesis that V P A increases oxidative stress in rats that in turn is associated with liver toxicity. 15-F 2 t Isoprostaglandin (15-F 2 tlsoP), a free-radical catalyzed, lipid peroxidation breakdown product of arachidonic acid, was measured as an indicator of oxidative stress. Our findings showed a dose-dependent elevation in plasma and liver 15-F 2 t lsoP with plasma concentration-time profiles similar to that of the drug in rats given a single high dose of V P A . This increase in 15F 2 t lsoP did not involve cytochrome P450-mediated biotransformation even though rats treated with both phenobarbital (PB) and V P A resulted in greater levels of 15-F 2 t lsoP compared to rats treated with only V P A . These results prompted further mechanistic studies in rats to establish an association between V P A glucuronidation and 15-F 2 t lsoP levels. V P A glucuronidation, the major V P A biotransformation pathway, correlated with 15-F 2 t lsoP formation. Levels of both 15F 2 t lsoP and VPA-1-O-acyl glucuronide (VPA-G) were elevated by P B and reduced by inhibitors of VPA-glucuronidation in rats after a single dose of V P A . The fluorinated analogue of V P A (afluoro-VPA), which was a poor substrate for glucuronidation, did not elevate 15-F 2 t lsoP levels. To determine whether there was a temporal relationship between VPA-associated oxidative stress and hepatotoxicity, rats were given high daily doses of V P A for 14 days. V P A elevated levels of 15-F 2 ,lsoP prior to the onset of hepatic necrosis and steatosis. An in vitro model using primary cultured rat hepatocytes also demonstrated that V P A induces oxidative stress as measured by elevated levels of 15-F 2 t lsoP and 2',7'-dichlorofluorescein (DCF). In hepatocytes with reduced levels of glutathione, these oxidative stress biomarkers were further elevated, and


In this work the concentration of biogenic amines in filtered and unfiltered wine during aging in oak barrels was studied. Red wine from Merlot grapes was used. The wine remained for 243 days in barrels of American oak (Quercus alba) and French oak (Quercus sessilis) from the Allier and Nevers regions. Results showed that the different degree of wine turbidity did not have any influence on the accumulation of biogenic amines during the aging period. Histamine and tyramine were degraded at the end of aging; however, the concentration of histamine in both matured wines was higher than 8 mg l−1, which could be a toxic danger to consumers. Putrescine and cadaverine were formed during aging and were not degraded. Phenylethylamine + spermidine were formed, above all, towards the end of the aging period, and the concentration of spermine did not show any appreciable variation.
