Classical sociology is based on an imagined community and the community or social categorization as defined by Toennies is its major theoretical background.The advent of the Internet has brought about various virtual communities,which are considered peers of the conventional communities by such scholars as Rheingold and Turkle. With such super-communities as FaceBook and MySpace,a re-consideration is needed in the scrutiny of the nature of the virtual community.Baktin's dialog theory is applicable in this study.


The importance of stochastic differential delay equations (SDDEs) derives from the fact that many of the phenomena witnessed around us do not have an immediate effect from the moment of their occurrence. A patient, for example, shows symptoms of an illness days (or even weeks) after the day in which he or she was infected. In general, we can find many "systems", in almost any area of science (medicine, physics, ecology, economics, etc.), for which the principle of causality, i.e., the future state of a system is independent of the past states and is determined solely by the present, does not apply. In order to incorporate this time lag (between the moment an action takes place and the moment its effect is observed) to our models, it is necessary to include an extra term which is called time delay. The SDDEs can be regarded as a generalization of stochastic differential equations (SDEs) and delay differential equations (DDEs). During the last few decades, many authors have studied SDDEs. some important results are given, for example, conditions which guarantee the existence and uniqueness of an analytical solution [13, 14, 15] and stability conditions for both exact solutions and numerical solutions, etc. [2, 6, 11, 16]. It is well known that in the deterministic situation there is a very special delay differential equation: the pantograph equation


The development of Plasmodium falciparum parasites resistant to artemisinin (ART), so far only reported present in south-east Asia, poses a big threat towards the malaria affected part of the world. Since we do not yet know how artemisinins work or exactly what constitutes ART resistance, an exact way to monitor its spread is difficult. Some genes have been proposed as molecular markers for a decreased ART suspectibility when containing certain polymorphisms. Among these are the genes coding for P. falciparum chloroquine resistance transporter (PfCRT), P. falciparum multidrug resistance 1 (PfMDR1) and now most recently the gene located on chromosome 13 that coding for the K13 kelch protein, also known as the 'K13 propeller'. In this study data from 38 malaria patients in Igombe, Tanzania, treated with artemisinin-lumefanterine (AL) combination therapy, was used to determine the efficacy of AL treatment. Also, for the first time in this area, the prevalence of variation inside the K13 domain in the malaria parasites was quantified. Patients' clinical status and parasite blood levels were followed up for three days and blood samples were collected for DNA sequencing. Results proved AL has a high efficacy in the area, curing all patients within three days. Furthermore, one out of 34 patients carried a possible polymorphism in its K13 nucleotide sequence. The results are consistent with the clinical situation in Tanzania, where ART combination therapy today has a good effect and resistance is not present, however, it is not possible to say


We investigate WB-height-unmixed of tensor product of distributive lattices: Cohen-Macaulay rings related to tensor products of distributive lattices are constructed using the method of Stanly and Reisner.


This paper deals with the position control of a servo-pneumatic system in presence of mismatched uncertainties. Pneumatic actuators are used in many industrial applications; such as haptic interfaces, mechatronic systems and robotics. Restriction of control effort, to apply directly on the mismatched uncertainties, causes problem to cope with these kinds of uncertainties. Nonlinearities due to internal and external disturbances such as friction force between piston seal and cylinder wall; make it difficult to control these actuators. Thus modeling and identification of friction parameters is an essential part of the controller design procedure. Using simple model for friction such as stribeck model could help to put more effort on design a controller. Also bounded uncertainty owing to unmodel dynamics of friction is considered. First the system dynamics represented. Then By using multi surface sliding mode control scheme, mismatched uncertainties that appear in state equation of system dynamics are compensated. The simulation results are compared with experimental measured system output. Asymptotic stability of the closed loop system is proven by using Lyapunov method; experimental results show that the proposed controller can deliver good tracking performance and it is robust to uncertainties.


It is shown that the complete set of circular shift invariants called the Q-spectrum, of the Walsh-Hadamard transform (WHT) of a periodic sequence is related to the cyclic autocorrelation of the given sequence through the Hadamard matrices. It is also shown that the modified WHT (MWHT) of the cyclic autocorrelation yields the Q-spectrum within some scale factors. This is analogous to the discrete Fourier transform (DFT) case, i.e., the DFT of the autocorrelation of a sequence yields the shift invariant power spectrum. The Q-spectrum can be computed efficiently using the MWHT rather than the WHT. A physical interpretation for the Q-spectrum is also provided. The motivation for this study is to show that while the WHT is inherently associated with the notion of dyadic time shifts, it does have analogous properties with respect to cyclic time shifts.


To deal with the incompleteness, uncertainty and complexity existed in modern information processing , the researches and applications of rough sets theory to intelligent information processing are discussed in terms of the methodology of rough set theory, and the future research tendencies are also outlined. In addition, some approaches to intelligent information processing techniques are provided.


In March 2016, the International Criminal Tribunal for the Former Yugoslavia (ICTY) convicted former Bosnian Serb leader, Radovan Karadžić, of genocide and crimes against humanity and sentenced him to forty years imprisonment.1 In particular, Karadžić was found guilty of genocide in Srebrenica, the persecution of Bosnians and Croats throughout Bosnia and Herzegovina, terrorizing the population of Sarajevo, and taking United Nations (U.N.) peacekeepers hostage.2 According to the ICTY Trial Chamber verdict, the crimes were committed as part of four joint criminal enterprises (JCE) in which Karadžić was a protagonist.3 In July 2016, Karadžić announced, through his defense counsel, that he would appeal the verdict on the ground that he did not get a fair trial—according to Karadžić's attorney, Peter Robinson, "[t]he trial chamber considered him guilty in advance and then constructed the verdict to justify its presumption."4 Robinson also stated that "[t]he chamber concluded [Karadžić] had an intention to kill the captives from Srebrenica on the basis of its interpretation of a coded telephone conversation. Such a way of drawing conclusions is unfounded and incorrect, so the verdict is unfair."5 The ICTY prosecutors announced, on their end, that they also would appeal the verdict in order to ask "for Karadzic [sic] to be found guilty of the genocide in seven other Bosnian municipalities in 1992, and for his sentence to be raised to life imprisonment."6 The appeals chamber of the Mechanism for International Tribunals, which is taking over the remaining work of the ICTY as it shuts down,


Earlier reports from their laboratory showed the induction of the insulin-deficient diabetic state in adult rats was associated with an accumulation of zinc, copper, and a metallothionein-like zinc and copper binding protein in the soluble fraction of liver and kidney. Based upon chromatographic and electrophoretic properties, -SH to metal ratio and amino acid composition, they now report that elevated concentrations of metallothioneins (MT)-I and -II are indeed present in diabetic rat liver and kidney cytosol. The relative rates of MT synthesis in tissues from diabetic and control rats were measured by comparing incorporation of /sup 35/S-cysteine into MT vs. total cytoplasmic proteins at 5 h after injection of the precursor. The relative rates of MT synthesis in livers from rats diabetic for 10 d and fed either chow or purified diet containing 13 or 35 ppm copper were 1.4, 2.3 and 2.8 times greater, respectively, than control rats fed the same diets. Higher relative rates of MT synthesis were also observed in kidneys from diabetic rats fed purified diets compared to controls. Maximal relative rates of MT synthesis in diabetic liver and kidney were observed at 4 and 10 d, respectively, after onset of diabetes. The half-lives of cytoplasmic MTmore » in liver and kidney from diabetic (10 d) rats were 1.3 and 2.6 days, respectively; half-lives of MT in control liver and kidney were 5.0 and 2.1 days, respectively.« less


Rice husk is an agroindustrial residue which, when adequately burned and ground, may become an important pozzolan to be added in mortars. One factor contributing to the feasibility of its use is that of the 10 million tons of rice produced annually in this country, two million tons of husk remain, which can produce about 400 thousand tons of ash - enough to supply the market for mortars, concrete and others. This large amount of material has become an environmental problem because it is being discarded inappropriately. Seeking a viable use of rice husk ash in the civil construction, the present research studies the variation in mortar behavior with different levels of RHA (Rice Husk Ash). Prismatic specimens were used, measuring 25x25x285mm, moulded with 0% (reference), 5%, 10% and 25% RHA. The influence of the RHA's was verified through the following tests: efficiency of pozzolanic materials in avoiding expansion and alkali-aggregate reaction. The result obtained in the expansion reduction test (NBR 12651) showed that RHA reduces considerably the expansion of mortars due to reaction with the alkalis in the cement (94.29%), with the minimum reduction required by the norm for a pozolan being 75%. Although the expansion values in the alkali-aggregate reaction test (ASTM C-1260) remained above the limit allowed to consider the material innocuous, RHA levels of 5% as well as 10% obtained better results (expanded less) then the reference line.


public and private institutions, schools, orphanages, hospitals and other institutions. When we talk about palliative care, especially in developing countries such as Brazil, which still have numerically disproportionate palliative care services, if we consider the number of the population,2 community education strategies are very relevant to demystify misconceptions and to increase knowledge about civil rights to the end of life, increase knowledge about palliative care, advance directives, control of pain and other symptoms, as well as emotional, psychological and spiritual care of people at the end of life.


We study the combined effect of buoyancy and thermocapillary forces on the flow of a low Prandtl number liquid (Pr = 0.015) contained in a rectangular cavity with differentially heated vertical end walls. The finite volume method was used to discretize the partial differential equations of the mathematical model. The flow structure and thermal fields are represented by stream functions and isotherms.


This article presents the main results of a study that examined the connections between inequali- ties in access and permanence in higher education, the student aid and employability for a sample of graduates from UFMG. The comparative analysis of the socio-economic status of the gradua- tes, composed both by students who received aid as well as by those who did not, shows that, in the case of the sample in this study, the remuneration of graduates who received aid is in equal terms and affected by the same factors that influence the composition of the income of the others graduates. The present data revealed that income is strongly related to career. According to re- search on the relationship between schooling and access to the labor market, professionals with high levels of education receive on average higher incomes than received by workers with little or no education. The analysis revealed that by helping poor students obtain a higher education diploma, the student assistance programs help them become skilled and join the labor market carrying valued credentials, increasing their chances of upward social mobility.


In the rat, unlike other species, acute insulin-induced hypoglycemia does not lead to an increase in glucose production and the restraining effect of insulin on hepatic glucose production predominates (Cole, Achou and Hetenyi 1973). The purpose of the present investigation was to determine the effect of chronic continuous insulin administration for 6 days and its consequent hyperinsulinemia and hypoglycemia on the glucose turnover rate and splanchnic glucose production in the rat.

Haemophia A is one of the commonest bleeding disorders occurring with a frequency of 1 in 5000 to 10,000 male births. 52 haemophilic patients 150 unrelated control women from non-haemophilic families were studied for allelic frequencies and heterozygosity rates of intragenic factor VIII gene related RELPs (Bcl I, Hind 111, 13 (CA)n repeats 22(AG)n (GT)n repeats XbaI/Kpnl) and extragenic markers (Bg III and Tag-I). Based on the results it is suggeted that Carrier screening and prenatal diaguosis for haemophilia A in Indian population should be to analyse these polymorphisms and in severe cases for inversion of intron 22 of factor VlII gene.


Aceh, an Indonesian province on the northern tip of Sumatra Island, has unique urban and rural environments and a rich cultural tradition. Aceh is the region into which Islam is believed to have entered Indonesia in the twelfth century and from which it is believed to have spread not only throughout Indonesia but also to Southeast Asia. Concerning this, Aceh's ties with Islam have a long and rich history. The study aims to examine the development of mosque in Aceh from precolonial to post colonial times. The methodology of this study is a qualitatif descriptive. The collected data is analized through library research and field observations. In doing this, the study shows that crossed cultural issues, social mix as well as political aspects have some impacts on the representation of Mosques in Aceh.


Nanowire is a kind of nanostructures and it usually has a high aspect ratio. Bolometer having nanowire as its active element is belonged to nanobolometer, compared to the microbolometer usually having thin film active element with area of several to tens square microns. A nanobolometer is expected to have many advantages, such as: very simple structure, small size, low noise, high specific detectivity and short response time. In this work, the optical and thermal properties of platinum nanowire in far infrared wavelengths are studied by using multiphysical finite element numerical calculation tool. Relationship between geometry size of platinum nanowire and its optical and thermal properties are revealed. Due to antenna-resonance electric-field-enhanced effect and small size effect, one absorption peak can be found in optical absorption curve of nanowire. The position of absorption peak is connected with the length of nanowire and the value of absorption peak is mainly impacted by the width and thickness of nanowire. When the aspect ratio is too high, the position of absorption peak will move although length does not be changed. At last, a nanowire based nanobolometer which has great optical and thermal characteristics in the wavelength ranging from 8 μm to 14 μm is designed and simulated. Comparing to the previous reported device using the same structure, thermal performance parameter increases one order of magnitude.

Abstract We present and highlight the first results of the three main exoplanet surveys we are currently conducting at Universidad de Chile: CHEPS, Red Giant Exoplanets (radial velocity), and TraMoS (transit lightcurves). We have several interesting candidates at the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) project, which is aimed at searching for the currently missing southern bright transiting planets at a few m/s radial velocity precision. Using the same technique, we are also characterizing the planetary population in a constrained sample of Red Giant stars. The Transit Monitoring from the South (TraMoS) project is aimed both at improving transit parameters and at detecting any kind of lightcurve variability from several known southern exoplanet systems.


We give a relatively complete analysis for the regularization method, which is usually used in solving non-diierentiable minimization problems. The model problem considered in the paper is an obstacle problem. In addition to the usual convergence result and a-priori error estimates, we provide a-posteriori error estimates which are highly desired for practical implementation of the reg-ularization method. The purpose of the paper is to give a relatively complete analysis of the regularization method for solving non-diierentiable minimization problems. In addition to the usual convergence analysis and a-priori error estimates, we will also provide a-posteriori error estimates. The model problem to be solved is an obstacle problem considered in 15].

We investigate the resonant interaction of a dipolar j=0\ensuremath{\leftrightarrows}j=1 angular-momentum transition with the quantized field in a dielectric sphere. New features arise on account of the degeneracy of atomic levels and field modes with low azimuthal angular momentum, in slightly deformed spheres (oblate spheroids). For TE-mode excitation we obtain the dynamics of a degenerate \ensuremath{\Lambda} or V configuration with the usual coherent-state collapse and revivals. For TM-mode excitation new behavior is found: due to interference between \ensuremath{\sigma}- and \ensuremath{\pi}-polarized transitions, which can be controlled by the atomic position and/or dipole orientation, coherent-state revivals and the corresponding atom-field energy exchange may be suppressed or delayed. \textcopyright{} 1996 The American Physical Society.


This article addresses the tutoring experience to a group of eight professionals - connected with superior education - in different health areas and in different cities of the country. It is a distance-learning major course, on-line and face-to-face attendance, with active methodologies on problematizing perspectives. In on-line and face-to-face attendance, problem-situations were worked on from a study guide containing 22 texts elaborated by the course organizers and tutors, who reported situations experienced in their daily lives as health professionals. Likewise, accounts of the practice were also worked on, elaborated by the course attendants who abstracted from their professional realities, called "village". All Problem-situations as well as Accounts of Practice were selected by the majors which enabled them - according to their reports - to refine their knowledge in the three target areas of the course: educational, caring, policy-managing.


Aiming at dealing with the complexity of connected component labeling conflict, one labeling method based on contour tracking is put forward. Using different markers for different objects and inner and outer contour solves multi-objects contour tracking effectively. Through scanning the binary image once, morph character parameters such as area, perimeter, form-center, long diameter and short diameter, roundness and rectangleness, are extracted accurately. The application in the duck eggs' quality detection indicates that this method is good for extensive use.


This issue concerns the predictive power of the term of structure of interest rates for real activity in Tunisia. Few papers are concerned with this question in developing countries. In Tunisia, we find a strong positive relationship between the spread across long and short rates and future changes in real GDP. This relationship is strongest at three quarter or just beyond. The results obtained in this paper confirm that the predictive power of financial variables observed in some developed countries extend also to some developing countries like Tunisia. It is interesting because Tunisia has the particularity to be a small open economy, and the relationships between domestic financial variables and real activity is obviously unaffected by the openness of the economy. Financial variables seem to have an efficient predictive power on future output at short and long horizons. Term differential contained leading information on the growth of output, additional to those provided by other financial variable like real interest.


The low room-temperature ductility Fe{sub 3}Al-based alloys is associated with their environmental embrittlement. Reducing the aluminum level from 29 to 16 at % has been found to be an effective method in essentially eliminating the environmental-embrittlement effect and increasing the room-temperature ductility value to over 25%. This paper will present data on alloy compositions, melting, casting and processing methods, and mechanical properties. Plans for future work on these alloys will also be described.

ABSTRACT Social media has become increasingly popular among the young generation. Previous research suggests that social media consumption is correlated with fear of crime and punitive attitudes toward criminal offenders. Yet, little is known about whether social media consumption influences perceived commitment to the police occupation among young generations. This is particularly important since the police profession is currently experiencing a 'workforce crisis.' Using a convenient sample of approximately 300 young adults, the current study examines the link between social media exposure and police occupational commitment after controlling for the key audience characteristics. Findings reveal that the longer time that individuals spend on social media, the less likely they would attach to the police occupation. Their commitment to the police occupation is also influenced by their knowledge of police work, including police work personality and the police-citizen relationship. Implications for future research and police departments are discussed in the end.


This work proposes using the changes in the LEDs' spectral emission induced by temperature variations to implement emitters for new communication channels in Optical Camera Communication (OCC) systems. If a camera can discriminate the shift in LEDs' spectral response, these modifications can be contemplated as a new data channel. The main advantage is that new channels can be obtained from the same physical optical emitter device, only temperature changes are needed. Thus, in this work, the use of multispectral or hyperspectral cameras as OCC receivers is proposed to increase the number of available communication channels, taking advantage of the high spectral resolutions of the camera devices.


【Torticollis is a deformity of the neck that shows tilting of the head toward the affected side and rotation of the chin toward the opposite side. In many cases with this condition, unilateral tightness of the sternocleidomastoid muscle is found frequently with fibrous tumor. The analysis of 43 cases of congenital muscular torticollis and result of their physical therapy are reported. The research was from Jan. 1, 1990 to Dec. 31, 1995 at Ulsan Dong Kang Hospital. The results obtained were as follows. 1. There were 30 males(69.8%) and 13 females(30.2%). Age distribution of patients showed below 2 month 20 cases(46.5%), above 1 year 7 cases(16.3%), $5{\sim}6/11{\sim}12$ months 4 cases(9.3%), and $7{\sim}8$ month 2 cases(4.6%). 2. 25 cases(58.1 %) were on the right and 18 cases(41.9%) on the left side. Torticollis was mild to moderately severe in mild 22 cases(51.1 %), moderate 18 cases (41.9 %) and severe 3 cases(7%). 3. There were normal spontaneous delivery in 36 cases(83.7%), Cesaean section in 4 cases (9.3%) and breech presentation in 3 cases(7%). Sequence of birth, the 1st born babys were 30 cases(69.8%) and the 2nd born babys were 13 cases(30.2%). 4. Above fair result of physiotherapy were 36 cases(83.7%). 5. Of the 43 cases with fellow up, above fair 32 cases(74.4%) and poor 11 cases(25.6%) showed. As conclusion, passive stretch exercise of sternocleidomastoid muscle with early torticollis diagnosis seems more successful in recovery than no exercise.】

The environment confronting modern organizations possesses high uncertainty arisen from ever-increasing complexity, competitiveness and dynamics, which make organizational characteristics including organizational structure to be experiencing great alteration so as to suit the environment. The kernel of organizational management is decision, and the process of decision-making is just the one of information processing. In this paper, as an emphasis, the problem of organizational structure design under uncertain environment was studied from the angles of organizational decision-making and information communication. A model of organizational decision considering uncertain environment was set up. On the basis of the model, the concept of organizational structure value was introduced. Integrating qualitative and quantitative methods derived a mathematical expression reflecting their relations among organizational environment, organizational decision and organizational structure. According to the expression, some conclusions meaningful to organizational structure design under uncertain environment were obtained. The study shows that, under the environment of uncertainty, organizational structure should keep high flexible for the purpose of improving decision effectiveness; the more information sharing among decision units enables organization to make the better decision; and the network organization whose communication channels are flexible and open has advantage over the hierarchical organization whose communication channels are rigid and restricted. However, a specific organizational structure design should depend on varied kinds of factors. Such factors along with their influences on organizational structure design were investigated as well.


A mobile robot can identify its own position relative to landmarks, the locations of which are known in advance. The main contribution of this research is that it gives various ways of making the self-localizing error smaller by referring to a sensitivity which is defined as the ratio of the localizing error to sensor error. In this paper, the authors propose the index to evaluate the accuracy of the self-localizing methods. And then, a rational way to minimize the localizing error is proposed. Finally, we discuss a method to reduce the computational cost of selecting the best self-localizing method.


The basic purpose of this study was to measure the attitudes of teachers toward pupil control (pupil control ideology) and to show the relationships between their attitudes and selected personal and situational factors. The underlying assumptions were: (a) a teacher's pupil control ideology can be measured, and (b) a teacher's pupil control ideology has considerable influence upon behavior, (performance). -- Pupil control ideology was, conceptualized as a continuum, ranging from extreme "custodialism" to extreme "humanism." A custodial ideology stressed the maintenance of order and traditional authoritarianism; a humanistic ideology emphasized the psychological and sociological bases of learning and behavior. -- The relationships between the dependent variable, Pupil .Control Ideology and nine other selected independent variables --- age, total teaching experience, sex, age level of students taught, hierarchical position in the school, length of training, marital status, years of administrative experience and subject taught --- were examined. -- The population chosen for the study consisted of all the full-time and part-time personnel (excluding non-professional staff) in the Comprehensive Schools in Harlow, England. Teachers were asked to complete a four-page questionnaire (Personal Data Sheet and PCI Form) which solicited their personal opinions on twenty statements about schools, teachers and pupils by choosing one of five possible answers: A --- strongly agree, B --- agree, C --- undecided, D --- disagree and E ---strongly disagree. -- In quantifying the answers 5 points were given to A, 4 to B, 3 to C, 2 to D and 1 to E. Statements five and thirteen were scored in the opposite direction. On this basis an extremely "custodialistic" respondent could receive a maximum score of 100 while an extremely humanistic respondent could receive a minimum score of 20. The "average" score theoretically would be 60. -- Of the 503 teachers in the Population, 326 completed a questionnaire. The range in individual PCI scores was from a low of 25 to a high of 87. The mean for all teachers responding was 57.9. -- The personal and situational variables were related to teachers' pupil control ideology by means of Analysis of Variance, t-tests, the Scheffe Multiple Comparison of Means Test and the Pearson Product-Moment Correlation Coefficient. The effects of intervening variables were controlled for by Covariance and Partial Correlation. Finally, comparisons of the study's findings were made with those reported in other research. -- Subject taught was the variable most strongly related to teachers' pupil control ideology; teachers of "academic" subjects were significantly more humanistic in their pupil control attitudes than teachers of "practical" subjects. In the case of the variables hierarchical position in the school and length of training, though not significant, the results were in the expected direction. The existence of relationships between variables was accepted at the .05 level of confidence. -- The results suggest that: (1) other factors, not considered in this study, may account for the range in teachers' pupil control attitudes, (2) type of training may be more closely related to pupil control ideology than length of training, and (3) the degree of responsibility to superiors and parents for the safety of pupils and equipment is directly related to custodial attitudes on the part of teachers.


This article discusses the challenges that contemporary technology present to records management. The costs of traditional records management are increasing. At the same time Cloud computing provides an exciting opportunity to contain costs while increasing organizational capability. Good records management is fundamental to the sustainability of organizations but is seldom seen as anything other than a burdensome addition to the day job by employees. In grappling with the implications of digital and paper records, records managers are not yet dealing with the fact that the sheer economics, volume and challenge of managing information — as records or other 'stuff' — simply mandates an automated technical easy to use solution. The Cloud, because it operates at the level of content, can drive dramatic change in the professions working on content management and address the continual expansion in the content created — and this includes forward thinking records managers. The Web together with the Cloud also delivers a new challenge to records management — to open up content for others to use in inclusive participation not hide it away for exclusive use. The article argues that Cloud based innovation will stimulate organizations to reconsider what information they wish to protect and what to release. In a digital world transparency rather than protection will be the stronger influence as seen in the UK's government plans for opening up data. Organizations will use far more information from the Web and internally will see that it has become simpler and better to recreate much of the information, now protected as records, than to rely on stored old versions. The new records management lifecycle needs to promote an obsession with content use rather than protection. The capture of contextual data at source will transform the way a record can be used. The cost of storage will cease to be an issue instead new values of storage will drive policy. Records management will become use based not store based and placing the new activities of records management at the heart of the living company.


Although alpha fetoprotein and human chorionic gonadotropin are present in the serum of some patients with testicular tumors, measurement of these substances has had limited clinical value because the conventional assays are relatively insensitive. With the development of radioimmunoassays for alpha fetoprotein and for the beta-glycoprotein chain of human chorionic gonadotropin, it is possible to detect much lower serum levels of these products. Preliminary reports have suggested that serial determinations of these markers by radioimmunoassay can be useful clinically in patients with nonseminomatous germ-cell testicular tumors.1 , 2 We here describe our 22-month experience with the measurements of alpha fetoprotein and human . . .


Dragonflies are classified into the Odonata order. The existence of dragonflies can be used as bioindicators of good water, related to their life cycle. The difference of habitats in the Kedung Kopong and Banyak Angkrem areas affects the diversity of dragonflies found in the location. The purpose of this research was to determine the types of dragonflies and their habitats in the Kedung Kopong and Banyak Angkrem areas. The method used in this research is the point count, which is by tracing the predetermined transects and divides it into some points. The distance between the points is 15 meters while the diameter of the points is 10 meters. The result of data collection of dragonflies in the Kedung Kopong and Banyak Angkrem areas as a whole obtained 19 species which is divided into 7 families, they are Aesnidae (2 species), Libellulidae (10 species), Calopterygidae (1 species), Cholorocyphidae (1 spesies), Coenagrionidae (2 species), Euphaeidae (1 species), and Platycnemidae (1 species). Habitats in the Kedung Kopong areas is the river. Meanwhile, in Banyak Angkrem are settlements


The host range of Pyrenophora teres f. teres (net blotch pathogen of barley) isolates from California was studied in the growth chamber and in the held. In the growth chamber, 28 of 43 gramineous species tested were infected by at least one of six P. t. teres isolates originating from Hordeum vulgare or H. murinum subsp. leporinum. Sixty-five of 95 species evaluated in the field also were infected, and 38 new host species were identified. On a generic basis, 15 of the 16 genera tested had susceptible species; this list included four genera (Cynodon, Deschampsia, Hordelymus, and Stipa) never reported to contain hosts for P. t. teres


Monoprotonated oxonium cations (such as 2)
and quinonoid dications (such as 5)
of 2,3-, 2,6- and 2,7-dimethoxynaphthalenes are described. Their role as direct
substrates in sulfonation reactions is discussed together with details of
the sulfonation mechanism for 2,3-dimethoxynaphthalene (2,3-DMON), which is
presented as a characteristic example. Steady sulfonation rate constants of
2,6- and 2,7-DMON in 80–88% H2SO4 are a result
of the DMON protonation equilibria. Binding energies and heats of formation
were calculated for several mono- and disulfonic acids of DMONs. Substituent
effects are discussed.


The results of testing the modes of robotic laser welding of spatial welded joints of thin-walled products from heat-resistant steels are considered. Comparative studies of the influence of the parameters of various methods of industrial welding on the metallography of the weld and the technological strength of the welded joint are presented. The resistance of welded joints against the formation of crystallization (hot) cracks is evaluated.


Java network programming covers a wide range of teaching,more new technology and limited experiments time.In this paper, from the reality of teaching,we introduce the theoretical and experience teaching contents,and carry out some useful exploration of teaching methods.The research and exploration will benefit for Java network programming teaching.


Extremely Thin Absorber (ETA) solar cells were made using chemical-bath-deposited Sb2S3 as the absorber and TiO2/CuSCN as the interpenetrating electron/hole conductors. A solar conversion efficiency of 3.37% at 1 sun illumination was obtained. Surface oxidation of the Sb2S3 formed a passivation layer on Sb2S3: without this oxidation, much poorer cells were obtained. Preliminary stability measurements showed good stability over 3 days of illumination (at 60 mW/cm2) under load.


Predicting the (distributional) meaning of derivationally related words (read / read+er) from one another has recently been recognized as an instance of distributional compositional meaning construction. However, the properties of this task are not yet well understood. In this paper, we present an analysis of two such composition models on a set of German derivation patterns (e.g., -in, durch-). We begin by introducing a rank-based evaluation metric, which reveals the task to be challenging due to specific properties of German (compounding, capitalization). We also find that performance varies greatly between patterns and even among base-derived term pairs of the same pattern. A regression analysis shows that semantic coherence of the base and derived terms within a pattern, as well as coherence of the semantic shifts from base to derived terms, all significantly impact prediction quality.


Source-follower-based (SFB) continuous-time low-pass filters (LPF) have the advantages of low power and high linearity over other filter topologies. The second-order SFB filter cells, which are key building blocks for high-order SFB filters, are often realized by composite source follower with positive feedback. For a single branch 2nd-order SFB cell, the linearity drops severely at high frequencies in the pass band because its slew-rate is restricted by the Q factor and the pole frequency. The folded 2nd-order SFB cell provides higher linearity because it has two DC branches, and hence has another freedom to increase the slew rate. However, because of the positive feedback, the folded and unfolded 2nd-order SFB cells, especially those with high Q factors, tend to be unstable and act as relaxation oscillators under given circuit parameters. In order to obtain higher Q factor, a new topology for the 2nd-order SFB cell without positive feedback is proposed in this paper, which is unconditionally stable and can provide high linearity. Based on the folded 2nd-order SFB cell and the proposed high-Q SFB cell, a 264MHz sixth-order LPF with 3 stages for ultra wideband (UWB) applications is designed in 0.18µm CMOS technology. Simulation results show that the LPF achieves an IIP3 of above 12.5dBm in the whole pass band. The LPF consumes only 4.1mA from a 1.8V power supply, and has a layout area of 200µm × 150µm.


Mathematical representation is the center of mathematics learning. However, is the student's ability to interpret the form of representation good? In this study, we adapted multiple choice questions from the LOCUS assessment to describe how 30 semesters III students interpreted the bar chart and box plot. The students answered this multiple choice question by including the reasons. The results showed that 50% of the 30 students gave correct responses regarding the boxplot. These fifteen students stated that the box plot cannot be used to calculate a lot of data. However, these 15 students were unable to come up with reasons why the box plot could not be used to calculate a lot of data. The remaining 50% of students stated that other diagrams such as scatter plots, histograms and bar charts cannot be used to calculate a lot of data

The legal rights of property, and the power those rights conferred, once gave employers the unfettered right to direct and control their workers on the job. However, since June 20, 1960, as a result of four Supreme Court decisions, management9s "right to manage" has been significantly affected. Businessmen may be tempted to wonder if the Justices are not delivering questionable decisions that will seriously disturb our business system.


Study Data Tabulation Model (SDTM), defines standard structure for study data tabulations for regulatory submissions. This not only saves time and money but also furnishes a choice for sponsors to automate the process of standard data creation. SDTM defines general observation class which is further divided among three classes Interventions, Events and Findings. The SDTM does not allow the addition of new variable; In addition the supplemental Qualifiers special purpose model is used to capture non-standard variables. In some situations it is observed that collected data from the case report form can neither be represented within an Event nor in Intervention also it is not always easy to map information in supplemental qualifiers. In such situations findings about domain models are utilized. This paper discusses advantages of findings about model in certain situations. Case studies from the real life studies will be discussed to get familiar with Findings About.


Abstract : Biological and physical data were collected from four bendways within the river portion of the Tennessee-Tombigbee Waterway (TTW) from Columbus, Mississippi, to Demopolis, Alabama: Rattlesnake Bend, Cooks Bend, Big Creek Bendway, and Hairston Bend. During this study, the four bendways had not all been cut off and had been impounded for varying lengths of time. At the completion of the TTW project, all four of the bendways will be severed from the main navigation channel. Four distinct areas within each bendway were compared: above the bendway; within the bendway; below the bendway; and within the cut. Sampling was conducted from January 1979 to September 1980 to coincide with four different river stage/water temperature regimes: late fall-moderate flow/ decreasing water temperature; winter-high flow/low temperature; spring-high flow/rising temperatures; and summer-low flow/warm water temperatures with increased probability of thermal stratification. Data were collected for numerous physical and water quality parameters, phytoplankton and chlorophyll, benthic macroinvertebrates, and fishes. During early September 1980 a mollusk and aquatic macrophyte survey was conducted at all four bendways. Sediment analysis and bottom profiles indicated that the substrate composition of some of the bendways is changing. Overall, the substrate of the study area is changing from a sand-gravel-fines mixture to one of predominantly sand and fines. Areas of some bendways, in particular the upper areas, were accumulating sediments. At big Creek Bendway, this accumulation completely blocked water exchange between the river and the within-bendway areas.


While active work is being achieved in order to conceive very transparent, stable and user-friendly human-machine haptic interfaces, few works address the human factors and performance evaluation of haptic devices while being used in an actual operator interaction with a virtual environment. The article addresses the above aspects.


Objective:To investigate the neutoprotective effect of salvianolic acid on SHSY5Y neuronal cells against oxygen-glucose deprivation(OGD),and the role of superoxide anion on the effect.Methods:SHSY5Y neuroblastoma cells were exposed to OGD,salvianolic acid(100mg/L)and triethylenetetramine(1 mM),cell viability was measured by the MTT assay,opening of the mitochondrial permeability transition pore(MPTP),intracellular concentration of superoxide anion and calcium were evaluated via the fluorescence intensity of calcein-AM,HEt and fluo-3/AM.Results:After OGD,compared with the vehicle group,the MTT value was elevated significantly in the salvianolic acid group(P0.01),the neuroprotective effect of salvianolic acid was blocked by administration of triethylenetetramine;the fluorescence intensity of calcein-AM(P(0.05)),HEt(P0.05)and fluo3/AM(P0.01)was decreased significantly in the salvianolic acid group.Conclusion:Salvianolic acid protects SHSY5Y neuronal cells against OGD by inhibiting the production of superoxide anion which attenuates the opening of MPTP and the intracellular concentration of calcium.


We used the doubly labeled water (DLW) method to measure daily energy expenditure (DEE) in eight brother-sister pairs of free-living Marsh Harrier (Circus aerugi- nosus) nestlings. We calculated metabolizable energy intake (ME) from DEE and body-mass change. In each pair, males had lower body mass, DEE, and ME than their female siblings. On average, male body mass was 20%, DEE 19%, and ME 20% lower than that of female siblings. Thus, energy turnover was proportional to body mass. Because the average sex ratio at fledging in Marsh Harriers is 55% male, and the energy requirement of sons is 45% of the son-daughter pair, this sex ratio matches exactly that predicted by Fisher's theory (1930). A literature review revealed that DEE (kJ/ day) measured by DLW when nestlings were ap- proximately 95% of asymptotic or fledging mass scaled as 4.58 M 0-76 (where M = body mass in g) in 11 species of altricial nestlings, including the Marsh Harrier.

Assessment on the TAT and Rorschach of 20 men and 4 women, 25 to 64 yr. of age and in the mild or moderately retarded ranges, able to speak, allowed their differential psychiatric diagnoses. Behavioral observations and prior testing were also included in these evaluations, performed on referral.


The termite feeding preference for 200 kGy gamma-irradiated C. japonica sapwoodwas comparativelytestedwithlow-termite-resistant untreated wood specimens prepared from sapwood of Cryptomeria japonica, Pinus densiflora, Pinus radiata, Picea glauca and Populus euramericana. Termites showed the highest preference for gamma-irradiated specimens in no-choice, two-choice and 6-choice tests. The wood consumption of C. japonica was smaller than that of other wood species in both two-choice and 6-choice tests, although the gamma-irradiated C. japonica showed the highest wood consumption. These results suggest that gamma irradiation is effective for making wood more preferable to termites and that the gamma-irradiated wood is desirable as a substrate for bait toxicants for the purpose of termite management.


A microrheological method is employed for the first time to continuously and undisturbedly monitor variations of viscoelasticity of magnetorheological elastomers (MREs) based on silica-coated carbonyl iron particles (SiCIPs)-filled silicone during the curing process. Results indicate that the elasticity of MREs dramatically increases with increasing magnetic field intensity, which is much more significant in comparison with the slow process of silicone curing at 25 % and 40 % SiCIPs. The formations of chain-like structure of SiCIPs and cured network of silicone are recognized, both contributing to the rheology of MREs, suggesting the possibility of developing a facile method for adjusting the rheology and fixing the structure of a wide range of MREs by applying magnetic field during the curing of matrix.


The competitiveness of companies can be favored through practices aimed at innovation, especially when associated with sustainability. In the railway sector, innovation occurs from operational improvements, cost reduction and expansion of services provided. In this sense, the objective of this study is to point out the importance of innovation in the context of railway companies. The method used is a qualitative approach, with a descriptive and explanatory outlining. For data collection, interviews were conducted with three professionals who work in a company in the railway sector in the state of Sao Paulo. In the studied company, there is a directioning of actions based on sustainability in order to improve the performance of operational activities. The importance of investments in projects that emphasize the use of alternative materials and respect the planet's support capacity, such as the adoption of a renewable fuel, is emphasized. The study carried out demonstrated the potential for generating innovation applied to the Brazilian railway network, however, it is necessary to guide innovation in the process of the company's operations to mitigate environmental impacts.

The distribution, vertical ranges arid ecological requirements of six Dryopteris species occurring in the Tatra National Park are described in this paper and presented on maps and diagrams. Of the species studied, Dryopteris filix-mas and D.expansa appear to be the most common species extending up to the alpine belt. D.carthusiana also occurs frequently, although generally it does not extend beyond the timberline. D.dilatata and D.affinis are much rarer. The remaining species, D. villarii , was recorded from one locality. All six species occur on various slopes ranging from flat areas to steep mountain slopes with a wide range of aspects. Soils on which these species grow were usually moist or very moist, rich in organic matter. The Dryopteris species studied encounter on various types of soils which are derived both from sedimentary alkaline rocks and from acid rocks. The mentioned species generally show a wide ecological amplitude so far as soil acidity is concerned. They occur on soils with a wide range of magnesium content and medium or low potassium content. These soils are poor in available phosphorus. Some differences in habitat requirements of the six Dryopteris species are discussed in paper and presented graphically.


Fluid flow data are presnted for beds of uniformly sized spheres consolidated with resin over a porosity range from 36.4 to 12.3%. The data are analyzed in terms of an effective pore volume and equations are given for predicting pressure drop by use of a friction-factor-Reynolds-number plot.


AlGaN/GaN heterostructures grown by MOCVD method on sapphire and silicon substrates were test subjects. The capacity− voltage characteristic measurements have been run in 200Hz — 1MHz frequency range at planar disposition of mercury and second probe on the sample surface. The shape of typical C−V curves for the heterostructures with the upper undoped i−AlGaN and i−GaN layers at thickness 15—25 A have been analyzed. The appearance of a typical peak on the C−V curves at changing from depletion region to accumulation region has been registered for some structures with thickness of i−GaN layer 50A at low frequencies (f < 50—200 kHz). The height of this peak increased with reduction of frequency. It has been found experimentally that frequency at which the peak is registered can depend on the dislocation density in heterostructures. Possible explanation of the peak formation and band diagram modifications in these structures under an applied electric field have been presented. We show that using a Si3N4 passivation layer results in the formation of additional positive charge.

The article is devoted to the analysis of the history of the formation of choreographic schools and studios in Ukraine at the beginning of the 20th century. The formation of Ukrainian professional choreographic education in Ukraine is closely linked to the development of classics, with the formation of Western European, namely, the French and Italian schools and the first dance studios in the nineteenth century. In the first decades of the twentieth century. the system of educational choreographic establishments was started. The basic principle of studying in choreographic schools is the tradition of classical dance, which continues today. In conditions of economic decline, military and political struggle, there was a marked rise in cultural and scientific life, which was caused by the aspirations of the Ukrainian national revival. Only in 1918 the State Drama School was founded, the Ukrainian State Theater, solemnly opened by the Ukrainian Academy of Sciences. Ukrainian schools and gymnasia began to appear in different regions. In order to harmoniously combine in the structural forms of the national ballet and in the vocabulary of classical and folk dance, choreographers attempted to theatricalize folk patterns, making them more complicated by the virtuoso elements of classics. These searches were effective: for the first time in the history of the ballet theater classical and Ukrainian folk-stage choreography united, becoming a fruitful ground for creating a kind of domestic dance school. In general, the development of Ukrainian choreography in the early twentieth century took place in the context of social and historical and political developments in Ukraine. In this period there was a spiritual uplift, the embodiment of cultural searches, the emergence of powerful talents. A specific feature of this period of development of Ukrainian culture was its ideological and humanistic content, which relied on universal human ideals reproduced in the national genre forms. For the establishment of Ukrainian professional choreographic education in Ukraine from the first studios and schools in the nineteenth century. Of great importance was the mastery of the laws of the classics and the values of the Western European, in particular the French and Italian choreographic schools. It was at the beginning of the twentieth century. the foundations were laid and the system of educational choreographic institutions formed on the traditions of classical dance, which continues to exist and develop today.


A qualitative interpretation of Aeromagnetic map of Meghalaya - Assam has revealed a number of features giving the structural fabric of Shillong massif. From west to east, the Shillong plateau has been brought out in a general strike of NW-SE to NE-SW through E-W. While in the western part of the plateau the NW-SE lineaments appear to control the disposition of lithology, the E-W lineaments in the central part and NE-SW lineaments in the eastern part are predominant, probably due to the north to south Himalayan thrust. Further three zones of N-S lineaments orthogonal to Shillong massif, at the swerves, from NW-SE to E-W and E-W to NE-SW are indicated possibly representing crustal breaks. These are parallel to 90° E ridge and their association with magnetic bipolar anomalies relate to intrusive plug like bodies. As one of them is associated with carbonatite body, such bipolar N-S trending anomalies warrant ground check for their mineralisation potential.


A portable non-destructive instrument has been developed for the measurement of grape cluster volume using air displacement techniques. The design satisfies the producer's need to determine cluster growth curves in order to estimate the optimum time to start the harvest. Several ways of processing data were evaluated, including different models and parameters related to thermodynamic, mechanical and electronic aspects. Using an empirical calibration technique, the device performs with an acceptable accuracy for field measurements, with errors below 20 cm3 and R2 higher than 0.92. It is intended for sample volumes between 80 cm3 and 500 cm3. The instrument was intensively tested in three vineyards and for different atmospheric pressures, achieving good results and validating its use for harvest volume estimation. The instrument can be adapted so that it can be used for other types of fruit and vegetables.

Introduction: Leprosy elicits spectrum of clinical, immunological and histological features. It is classified into 5 types according to Ridley and Jopling classification. . Proper diagnosis, subtyping and treatment play the main role in decreasing leprosy case load. Histopathological examination of skin and nerve lesions is the gold standard for confirmation of clinically suspected cases and classification. Aim of the study: Present study was conducted to study various types of leprosy cases in our population and its clinico-pathological correlation. Materials and method: A three year retrospective study was conducted in which a total 28 clinically diagnosed cases of leprosy were included. Detailed clinical presentations and spectrum of cases were recorded. Skin biopsies from the lesions were stained with Hematoxylin-Eosin stain for histomorphological study and Fite Farraco stain for detection of acid fast bacilli. Results: Out of total 28 cases, 16 cases were of male and 12 cases were female (1.3:1). Average age of patients was 38.9 years. Most common presentation found was asymptomatic plaque (29.6%) followed by nodules(25.9%) , hypopigmented patch (22.4%), ulcer(7.4%) , erythematous plaque (7.4%) and mixed presentation in 7.4% cases. Clinically most common type of leprosy was Borderline Tuberculoid (BT) while histologically Borderline Tuberculoid(BT), Lepromatous Leprosy(LL) and Indeterminate Leprosy(IL) each comprised of 18.5% cases. Correct clinical subtyping was done in 39% cases with maximum correlation in Histioid leprosy(100%) followed by Type 1 lepra reaction (75%). Conclusion: The spectrum of leprosy shows considerable overlap. Therefore , both clinical and histological characteristics with staining for lepra bacilli is the best approach to arrive at a correct diagnosis of these cases.


During the 1990s, an initial teacher education program reform is launched in order to promote and introduce a series of changes. Nevertheless, research in the field of education has evidenced that the gap between disciplinary and pedagogical knowledge, along with the distance between theory and practice continue to be an issue in teaching experience. The present article reports on the findings of a qualitative research that delved into the life experiencesIII of students while undertaking the bachelor of sciences and education program at different levels, and who are currently carrying out their professional teaching practice. Findings reveal that the contents of student teachers' life experiences are mostly related to the need of control, a scarce questioning of the meaning of science teaching, and the search for professional appraisal. The latter have been emotionally experienced differently by students depending on how they have internalized and applied scientific knowledge in their practices. Thus, emotions range from high levels of anxiety in students of basic scientific knowledge and at a reflective stage within the teacher formation program, to a sense of adaption in those who have already had professional experience in the field of applied sciences; or sometimes they have experienced a mixture of both. The present study concludes that the practice based on scientific knowledge has a higher influence over the student teachers' life experiences if compared to the impact of teacher formation, due to the fact that their experiences as science students and professionals are rooted to a traditional approach that have framed their thinking and performance.

The weakening of the West's global domination and the growing unwillingness on part of the US to defend the liberal order have increased the importance of regional-level international politics. For the past decade, China and Russia have stood out among rising powers attempting to rearrange their neighbourhoods. A significant part of International Relations scholarship regards this drive for regional predominance as a natural and unavoidable consequence of rising material power. Analysing China's and Russia's flagship regional initiatives, the New Silk Road and the Eurasian Economic Union, this article offers a more nuanced explanation of rising powers and their role in contemporary international order. The article argues that China and Russia have different visions of regionalism and distinct views on how a regional order should be arranged. China defines regionalism in functional rather than territorial terms and sees its project as inclusive. The Chinese ruling elite regards the New Silk Road as a way of reinforcing China's links with the outside world and as furthering the benefits it harvests from globalization. Russia, in turn, interprets regionalism in spatial and historical terms, seeing it primarily as a way to reorganize the post-Soviet space. The Russian elite considers the Eurasian Economic Union to be a protectionist measure against globalization and a barrier against the influence of other actors. China defines principles on which cooperation is based in vague terms and emphasizes the flexibility and openness of its project. Russia opts for universal and legally binding norms, which reinforces the defensive nature of its regional project.


The effect of heating (72°C/15 s and 92 °C/60 s) of milk reconstituted from low-heat nonfat dry milk (NDM) and medium-heat NDM on the molecular state of proteins was studied. Heating at 92°C was found to affect the protein integrity in low-heat NDM and medium-heat NDM in a different way. Lower stability of micellar casein (a decrease in the content by 4.8%) and smaller β-lactoglobulin (β-Ig) content of the micellar pellet for medium-heat NDM (44%) than low-heat NDM (68%) were found. The effect of heating reconstituted milk on content and composition of protein particles insoluble at 110,000 g was dependent to a higher degree on the micellar κ-casein and soluble Ca contents than on the degree of whey protein denaturation. This was indicated by the change in the Ca/P (w/w) ratio in non-micellar fractions that decreased from 0.96 to 0. 93 for heated medium-heat NDM and increased from 0. 93 to 0.99 for low-heat NDM.


LaNiO3 material was synthesized by modified proteic method, calcined at 900 °C/2 h in air atmosphere and was applied to remove environmental contaminants. LaNiO3 phase with a perovskite structure was formed in the calcined material, which has a surface area of 22 m2 g-1 and is formed by fine particles agglomerated, with pH of the zero charge point of 7.44. The removal of a model pollutant (Turquoise Blue dye) indicated that the better removal occurs in acidic pH and with adsorbent's mass of 50 mg, showing average value around 90% of removal efficiency and 131 mg g-1 for adsorption capacity (q) value. The variable constants model was the one that best fit the kinetic. LaNiO3 material resisted the test conditions and the recovery process, and maintained its high adsorption capacity throughout the six regeneration cycles studied, which indicates that it is a promising material as an adsorbent of pollutants and does not generate waste during the process.


With the development of economy,the thickness of collapse loess encountered in engineering increased in recent years.The increasing of water content caused some serious problems to the operation of ash yard,such as the collapse loess foundation subsidece and cracks.This paper analyzes the influencing factors of collapse loess.Results show that there are two necessary factors for the loess to collapse,one is the structure of loess,the other is water infiltration or confining stresses.So water preventing can protect the loess against collapse.With an actual project,this paper illustrates the treatment design schedule of thick collapse loess,and this provides helpful refercence to the design of similar project with the same geological condition.


To know the effect of water treatment sludge (WTS) as a rice seedling culture soil, rice seeds are sown, germinated and grown on the culture soils mixed with different ratios of WTS to sand (100:0, 50:50, 30:70, respectively), and their growth effects was compared to that of control, commercial culture soil. When WTS is used as a culture soil for rice, the length and weight of the top part of rice seedling somewhat decreased than those of control treatment while their root length and weight in all WTS treatments significantly increased. Although phosphorus and potassium uptake of rice seedling in WTS treatments was slightly decreased, WTS treatment showed to develop root growth which is necessary in the seedling stage of all plane. Such a stimulatory effect on root growth of rice seedling was significant in the mixture ratio of 50% WTS to 50% sand.


PVA/chitosan film has been fabricated by using drop casting method. PVA/chitosan film is produced by dissolving 2% (w/v) PVA solution and 2% (w/v) chitosan solution. PVA/chitosan film is produced with weight ratio variation (w/w) 100/0, 75/25, 50/50 and 0/100. The film is fabricated using drop casting method in Petry dish with diameter 11 cm at room temperature and RH 50%–60% during seven days. The mechanical properties were characterized by using Universal Technical Machine (UTM) and UV-Vis to understand the physical properties of weight ratio (w/w) of PVA/Chitosan film by addition of plasticizer and calcium chloride. The film thickness tends to decrease with PVA content. The addition of chitosan will increase film thickness, and it will decrease swelling index, elongation (%), and transmittance of UV rays. The additions of plasticizer to PVA/Chitosan film will increase film thickness and elongation (%), and it will decrease swelling index, tensile strength and transmittance of UV rays. The crosslink of PVA/Chitosan film with calcium chloride will decrease film thickness, swelling index, elongation (%) and transmittance of UV rays, and increase tensile strength.

In the 21th century,China's agricultural product trade developed quickly.But compared with the rapid development of the import of agricultural product,the export of agricultural product developed relatively slow.The reason of the relatively slow development is be made up of the internal factors and the external factors,such as the irrational structure of China's agricultural products trade and the deterioration of the external environment.How to overcome the internal and external adverse factors and promote China's agricultural export is worthy of an in-depth study.


Mechanical ventilation of newborn has been practiced for several years with several advances made in the way. As compared to the Western world and our neighbouring countries, neonatal ventilation in our country is still in its infancy. Objectives: To analyze the common indications and outcome of neonates requiring mechanical ventilation. Methods: This was a prospective observational study conducted on neonates requiring mechanical ventilation within first 24 hours of birth over a period of nine months. Results: Birth asphyxia was the commonest indication for ventilation (59.67%) followed by asphyxia with meconium aspiration syndrome (MAS) (17.74%), hyaline membrane disease (HMD) (8.06%), MAS (6.45%) and intrauterine pneumonia (6.45%). Out of 62 babies, 22 (35.48%) survived. Babies with asphyxia had highest survival rate (51.35%). Neonates with HMD did not survive. Term babies and babies weighing ≥2500g had higher survival rate of 40.47% and 41.46% respectively, while babies less than 32 weeks had survival rate of 16.66% only. Conclusions: Mechanical ventilation reduces the neonatal mortality; hence, facilities for neonatal ventilation should be included in the regional and central hospitals providing level II neonatal care.

Mysids often dominate mobile benthic epifaunas of mid-latitude continental shelves. Macquart-Moulin & Ribera Maycas (1995) reported that the six most abundant species on western and southern European shelves are all strong diel migrators. Published daytime epibenthic sledge (sled) data from the surf zone to the shelf edge matched with published behavioural data on the most abundant species were used to test, confirm and extend that relationship to other coastal regions and to identify an association of abundant migrators with species that are important in fish diets. They also reveal another pattern: a correspondence between abundant surf-zone species and species that dominate estuarine faunas seasonally. Population concentrations at estuary mouths, sills of fjords and in the surf zone suggest a lifestyle dependent upon horizontal fluxes. Marine mysids that migrate between habitats are chronically undersampled in the field, however, and are underrepresented in food-web models. Unfortunately, no single methodology samples both pelagic and benthic individuals well and nearly all shelf measurements so far reported must be considered underestimates of local abundance. Mysids are major dietary components for many benthic and pelagic fishes, mammals, cephalopods and decapods, often for key life stages, and often because mysid migrations result in encounters with predators. Mysids can be extraordinarily omnivorous, with demonstrated capabilities to digest cellulose and diets spanning macrophyte detritus, more labile detritus, large microalgae, and smaller animals and heterotrophic protists. They can be sufficiently abundant and active to play roles in sediment transport. Contributing factors to their underappreciation have been the lack of fidelity of mysids to single habitats, coupled with higher fidelity of investigators to the study of single habitats. Sampling with classical methods has been problematic because of effective evasion by mysids, compounded by extreme patchiness associated with mysid schooling. Their frequent absence from coastal and even estuarine food-web models has not been more conspicuous because the combination of their migration and omnivory spreads their feeding impacts and because they are subsidised by horizontally imported plankton and seston and are themselves horizontally exported in the form of predator gut contents and biomass. They clearly link pelagic and benthic food webs in two important and ecosystem-stabilising ways, however, by feeding in both habitats and by succumbing in both habitats to both cruising and sit- and-wait predators. Consideration of resource and predation gradients and limited data implicate horizontal, diel migrations as well, extending these linkages, especially in the onshore-offshore direction. Somewhat paradoxically, the same features that have made them difficult to study by classical means, in particular schooling, diet breadth, ontogenetic change in diet and migration between habitats, suit migrating mysids well to new, individual- or agent-based modelling approaches. Moreover, benthic observatories deploying acoustic technologies with spatial and temporal resolution sufficient to resolve individual migratory behaviours promise powerful tests of such models.


There are no randomized controlled trials assessing the impact of noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP) on cardiac function in obesity hypoventilation syndrome (OHS). Objective: To determine the efficacy of 2 months of NIV, CPAP or lifestyle modification (control) on echocardiographic changes. Method: OHS patients (n=302) were sequentially randomized by: 1) severe obstructive sleep apnea (OSA), into NIV, CPAP or control; 2) non-severe OSA, into NIV or control. ABG, spirometry, six-minute walk distance, Epworth sleepiness scale, polysomnography and transthoracic echocardiogram were evaluated. Results: We analyzed 2 groups: 1) with or without severe OSA and NIV or control treatments (entire OHS group; n=222); 2) with severe OSA and NIV, CPAP or control treatments (severe OSA subgroup; n=221). In the entire OHS group, NIV improved the left ventricular (LV) hypertrophy (mass index: -6.6 g/m2; 95%CI -11/-2.1 vs 3.6; 95%CI -1.1/8.3; adjusted p Conclusion: Medium-term NIV therapy is more effective than CPAP and lifestyle modification in improving PAP and LV hypertrophy in OHS


One hundred superconducting RF cavities have been produced and accepted for the energy upgrade of LEP (LEP2). The specified Q-value is 4,109 (4.2 K) at the accelerating gradient of 6 MV/m. A statistical analysis of the cavity performance data and experience encountered along the mass production arc presented. After assembly of the individual cavities into cryomodules of four, and mounting of power and higher mode couplers, unforeseen problems on these auxiliary elements have hampered the installation into LEP.

But you can discover your own success formula using internal benchmarking, says the author. Here's how you do it. © 2002 Wiley Periodicals, Inc.


Unconscious perception᾽s influence on various cognitive processes is discussed. Two-processes theories are described according to which all cognitive processes can be divided into conscious and unconscious ones. We raise the question of thresholds of awareness. We consider that decision-making about awareness or non-awareness of the differences between the objects is an essential step in the process of sensory task solving. Th us, discrimination threshold can be explained as the threshold of awareness of difference between the objects. Refs 41.


Fatty acid–binding protein (FABP) regulates polyunsaturated fatty acid (PUFA) intracellular trafficking and signal transduction. Our previous studies demonstrated that the alteration of PUFA in the hypothalamus is involved in pain process. However, how FABP subtypes change during pain remain unclear. Here, we examined the expression changes and localization in the hypothalamic FABP subtype in postoperative pain model mice.


The COVID-19 crisis had a profound impact on firms. Firms which were more productive pre-crisis fared relatively better, particularly in countries with a more competitive business environment. Using survey data for about 8000 firms, including both small and large firms, in 23 emerging and developing countries in Europe and Central Asia, the paper finds that during the COVID-19 crisis, smaller firms were hit harder, and economic activity was reallocated toward firms with higher pre-crisis labor productivity. Countries with a strong competition environment experienced more reallocation from less productive to more productive firms than countries with a weak competition environment. The evidence also suggests that reallocation from low- to high-productivity firms during the COVID-19 crisis was stronger compared with pre-crisis times. Finally, the analysis shows that government support measures implemented in response to the crisis went to less productive and larger firms, regardless of their pre-crisis innovation. Thus, government support measures during the COVID-19 crisis may have had adverse effects on competition and productivity growth. As economies enter the economic recovery phase, it will be important for policymakers to phase out support measures as soon as appropriate and focus on fostering a competitive business environment. This paper examines the impact of the COVID-19 crisis on the reallocation of economic activity across firms and whether this reallocation depends on the competition environment. The paper uses the World Bank's Enterprise Surveys COVID-19 Follow-up Surveys for about 8000 firms, including both small and large firms, in 23 emerging and developing countries in Europe and Central Asia, matched with 2019 Enterprise Surveys data. It finds that during the COVID-19 crisis, smaller firms were hit harder, and economic activity was reallocated toward firms with higher pre-crisis labor productivity. Countries with a strong competition environment experienced more reallocation from less productive to more productive firms than countries with a weak competition environment. The evidence also suggests that reallocation from low- to high-productivity firms during the COVID-19 crisis was stronger compared with pre-crisis times. Finally, the analysis shows that government support measures implemented in response to the crisis may have adverse effects on competition and productivity growth since support went to less productive and larger firms, regardless of their pre-crisis innovation.


This paper presents a comparative analysis of photovoltaic (PV) street lighting system in three different lamps. Namely, a low pressure sodium lamp a high pressure sodium lamp and a fluorescent lamp have been used for installation in each mast to determine the suitable system to install in a typical rural area of Thailand. All three systems have been mounted with the same module type and wattage in different places within the Rajamangala Institute of Technology, Thanyaburi district, Pathumthani province of Thailand. An operation of solar street lighting system can be divided into 2 period of time, namely, at 18.00-22.00 hours and 05.00-06.00 hours. The design of a control circuit was experimentally done in this work. Protection of the battery from damage for deep discharge and overcharge by a controller was also considered. The life cycle cost analysis (LCCA) is the appropriate method for comparing three different lamps. The present worth of each system can be compared and the least cost option selected. LCCA was based on the key assumptions (year 2002). The results of comparative analysis of the PV street lighting systems with a fluorescent lamp has been the appropriate system for installation in a typical rural area of Thailand when the cost of lamps, system performance and possibility for purchasing the components of the system have been considered.

Radio-loud active galactic nuclei (RLAGNs) are rare among AGN populations. Lacking high-resolution and high-frequency observations, their structure and evolution stages are not well understood at high redshifts. In this work, we report ALMA 237 GHz continuum observation at 0${_{.}^{\prime\prime}}$23 resolution and VLA 44 GHz continuum observation at 0${_{.}^{\prime\prime}}$8 resolution of the radio continuum emission from a high-redshift radio and hyper-luminous infrared galaxy at z = 1.92. The new observations confirm the South-East (SE) and North-West (NW) hotspots identified by previous low-resolution VLA observations at 4.7 and 8.2 GHz and identify a radio core undetected in all previous observations. The SE hotspot has a higher flux density than the NW one does by a factor of 6, suggesting that there can be a Doppler boosting effect in the SE one. In this scenario, we estimate the advance speed of the jet head, ranging from ∼0.1c–0.3c, which yields a mildly relativistic case. The projected linear distance between the two hotspots is ∼13 kpc, yielding a linear size (≤20 kpc) of a Compact-Steep-Spectrum (CSS) source. Combined with new high-frequency (νobs ≥ 44 GHz) and archived low-frequency observations (νobs ≤ 8.2 GHz), we find that injection spectra of both NW and SE hotspots can be fitted with a continuous injection (CI) model. Based on the CI model, the synchrotron ages of NW and SE hotspots have an order of 105 yr, consistent with the order of magnitude 103–105 yr observed in CSS sources associated with radio AGNs at an early evolution stage. The CI model also favors the scenario in which the double hotspots have experienced a quiescent phase, suggesting that this RLAGN may have transient or intermittent activities.
