Public policy in the discursive captivity of «political science», «jurisprudence» and «management»
Authors: KOBETS Roman
Published: August 2022

This article outlines a discursive framework for understanding public policy uses in different narrative contexts. The framework describes a definition of the term «discourse,» its historic and intuitionally related nature, and how descriptions of «state» and «policy» transforms into legal, political science, managerial, and «public/state policy» discursive practices. The author postu- lates that the discourse of public policy is a place of a «clash of rationalities» in the industry. Because of this, the SS concludes that the essence of public policy, its perception, understanding, and reaction to it are determined by the dominance of certain institutional discourses and the dominance of their bearers: «political scientists», human rights defenders, lawyers, managers and their ideas about the nature of the state and its «politics». The dominant discourses have the na- ture of uncritical extrapolations, or transfers of certain rationality inherent in one area to another, qualitatively different from it. The consequence of such an expansion of rationality from one sphere to another is the «inadequacy» of the discourse. It then discusses a comparative explica- tion of fundamentals, which constitute the narrative practices of each discourse. Furthermore, it proposed an explanation of the subject specifics of «public policy» as an area centered around «problems,» «options,» «impacts,» and «interests / stakes,» and then traces the significant distor- tions and contortions of this topic in the semantic horizons of related discourses. The article focuses on the rising issues of public policy, depending on the specifics of the discourse — whether «political», «legal,» or «managerial». For example, «political science» discourse emphasizes the problems of the consequences of one of the dimensions of influence for the interests of different parts of society; «Legal» discourse focuses on one group of instruments of influence (norms); «Managerial» discourse draws attention to a separate stage of implementation of already estab- lished public policy. Finally, this paper indicates the dominance of such discourses and their dependency on the historical context of contemporary Ukraine.

Modeling of natural intelligence and dynamics of human thinking with the use of significant combinary space
Authors:   International Scientific and Training Center for Information Technologies and Systems of National Academy of Sciences of Ukraine and Ministry of Education and Science of Ukraine, N Тymоfijeva
Published: August 2022

To create artificial intelligence, it is necessary to identify the properties of natural and develop a way to model it. There are many definitions of artificial intelligence in the literature, but there is no exact definition of this science yet. Differ-ent authors model natural intelligence differently. For example, artificial intelligence is defined as the ability of a digital computer to respond to information coming to its input devices, almost as a certain person reacts in the same infor-mation environment. This approach is based on the principle of self-organization of the model and is called heuristic. Human intelligence is also seen as an intuitive system. The creative process is accompanied by various manifestations of emotions, and decision-making in natural in-telligence is carried out in conditions of uncertainty of various kinds. Studies show that in the problems of this class it is related to: 1) incomplete input and current information; 2) with fuzzy input information; 3) with vaguely developed rules for processing and evaluating information. Significant combinatorial spaces, in particular significant information spaces, were used to model the dynamics of human thinking. The latter has a combinatorial nature and exists in two states: tranquility (convolute) and dynamics (deployed), which deployed from convolute. Collapsed is given by an information sign that contains the properties of the expanded space. Information is primarily related to the functioning of the human brain and is in the subconscious or consciousness in the form of images, fragments of speech and so on. The transfer of information (thoughts) is car-ried out with the help of deployed information space through the speech space, through gestures, movements, through writing, graphics. Depending on the type of uncertainty, the classification of natural intelligence is given. We believe that the con-cept of intelligence is associated with such operations as information processing and evaluation. Based on this, human intelligence is conditionally divided into three levels: 1) a person follows the rules, which are clearly formulated and described without analysis of their accuracy (learning rules); 2) the individual analyzes information for accuracy and develops its own rules of conduct under different conditions (rules of self-study); 3) the ability for independent of exist-ing rules of analysis, processing and evaluation of information for accuracy (rules of intuition). Partial realization of artificial intelligence is carried out through the use of self-tuning algorithms and modeling of self-organization processes in nature.
Mathematical modeling of temperature fields in antenna reflectors of space vehicles
Authors:   National Technical University Dnipro Polytechnic, Ukraine, M Berdnyk
Published: August 2022

The main factor that determines the distortion of the shape of the reflectors in outer space is the temperature deformation due to the uneven distribution of heat fluxes in the structural elements. Therefore, it is important to develop models and methods for calculating temperature fields in reflectors with uneven distribution of heat fluxes on the surface. The use of such methods will reduce the number of expensive field experiments. The paper first constructs a mathematical model for calculating temperature fields in a parabolic reflex antenna, in the form of a paraboloid of rotation rotating at a constant angular velocity, taking into account the finite velocity of heat propagation as a boundary value problem of mathematical physics for the hyperbolic equation of thermal conductivity. that the thermophysical properties of the body are constant. At the initial moment of time, the body temperature is constant, and on the outer surface of the body are known values of heat flux which are continuous coordinate functions. To solve the obtained boundary value problem, a new integral transformation for a two-dimensional finite space was constructed. The formula of inverse transformation is given. Eigenvalues and eigenfunctions for the kernel of integral transformation are found using finite element methods and Galorkin. The division of the region into simplex elements was made. Thus the problem of finding eigenvalues and eigenfunctions was reduced to the algebraic problem of finding eigenvalues and eigenfunctions. After applying the constructed new integral transformation to the obtained boundary value problem, we obtained the Cauchy problem, the solution of which was found analytically. The obtained solution of the boundary value problem is twice continuously differentiated by spatial coordinates and once in time. The solution of the boundary value problem found can be used to modulate the temperature fields that occur in a parabolic reflex antenna. The paper first constructs a mathematical model for calculating temperature fields in a paraboloid rotating at a constant angular velocity, taking into account the finite velocity of heat propagation as a boundary value problem of mathematical physics for the hyperbolic equation of thermal conductivity with Neumann boundary conditions. Using the developed integral transformation, the temperature fields in the paraboloid in the form of convergent series by Fourier functions were found. The solution of the generalized boundary value problem of heat exchange of the paraboloid of rotation can be used to modulate the temperature fields that occur in the antenna reflectors of spacecraft.

The problem of clustering is a very relevant area in Data Mining of different nature. To solve this problem, there are a large number of known methods and algorithms, most of which work in batch mode, in conditions when the entire of data set is known in advance and does not change over the time. These methods are complex in software implementa-tion and are not without drawbacks. The aim of the work is to develop an adaptive neuro-fuzzy clustering method of distorted data based on proto-type-centroid strategy using evolutionary procedures, that solves the problem in online mode, when data are fed se-quentially in real time and is characterized by numerical simplicity and high speed. The problem of adaptive fuzzy clustering of distorted data by outliers and emissions, which are presented in the form of vector arrays, based on the strategy of the nearest prototype - centroid using evolutionary procedures, is con-sidered. The proposed approach is based on the online probabilistic fuzzy clustering procedure with the membership function of special type and the evolutionary cat swarm algorithm. Proposed adaptive neuro-fuzzy clustering method of distorted data based on prototype-centroid strategy using evolutionary procedures characterized by computational simplicity, high speed and accuracy of the results based on experimental studies. The modification of optimization procedure that based on cat swarm algorithm was propose. The proposed method is simple in numerical implementation, workable in the case when the data is distorted and are fed sequentially in online mode, that is confirmed experimentally.

The basics of the principles of creation and filling of the technopark of unmanned aerial vehicles (UAV) are offered. The business process of UAV registration in the technopark of the situation center robots is described. The use of attrib-utes (tags) to the UAV will increase the efficiency of a suitable device selection with a complete set that meets the task. It is proposed to organize regional situational centers, which will coordinate the work of state systems, urban life sup-port systems, private services on the one hand and UAV on the other as executors. An example of automatic UAV selection for operative solution of the set task is given. The system should be based on the classification of the UAV during registration and on the basis of the UAV compliance function to the specific task, key features of the UAV, the time required to complete the task, the distance to the task and the policy to involve the UAV in such tasks to select those devices, who can quickly perform tasks. The function of classification of a specific UAV by tasks is offered. The function takes into account the configuration of the UAV. For each task, experts and automation select weights that indicate how large the impact of certain typical modules to perform a particular task, and for each UAV in the data-base stores information about whether the UAV takes into account a certain characteristic, or there is a corresponding module. To update the approach to vocational training today, the task of creating interactive mock-up training sys-tems in real physical space is one of the main ones. The composition of the basic laboratory stand, its complete set and control system of the mobile modular robot which promotes mastering of basic functions of the UAV or mobile work of unearthly base are described.

Authors:   V. M. Glushkov Institute of Cybernetics of the National Academy of Sciences of Ukraine, V Sineglazov
Published: August 2022

The necessity of integrated navigation complexes (INC) construction is substantiated. It is proposed to include in the complex the following inertial systems: inertial, satellite and visual. It helps to increase the accuracy of determining the coordinates of unmanned aerial vehicles. It is shown that in unfavorable cases, namely the suppression of external noise of the satellite navigation system, an increase in the errors of the inertial navigation system (INS), including through the use of accelerometers and gyroscopes manufactured using MEMS technology, the presence of bad weather conditions, which complicates the work of the visual navigation system. In order to ensure the operation of the navigation complex, it is necessary to ensure the suppression of interference (noise). To improve the accuracy of the INS, which is part of the INC, it is proposed to use the procedure for extracting noise from the raw signal of the INS, its prediction using neural networks and its suppression. To solve this problem, two approaches are proposed, the first of which is based on the use of a multi-row GMDH algorithm and single-layer networks with sigm_piecewise neurons, and the second is on the use of hybrid recurrent neural networks, when neural networks were used, which included long-term and short-term memory (LSTM) and Gated Recurrent Units (GRU). Various types of noise, that are inherent in video images in visual navigation systems are considered: Gaussian noise, salt and pepper noise, Poisson noise, fractional noise, blind noise. Particular attention is paid to blind noise. To improve the accuracy of the visual navigation system, it is proposed to use hybrid convolutional neural networks.
FORMATION OF BIPOLAR PULSE CURRENTS IN THE LOAD OF CAPACITIVE ENERGY STORAGES OF ELECTRIC DISCHARGE INSTALLATIONS

A method is proposed for stabilizing the transient discharge processes of capacitive energy storages (CESs) of electric discharge installations (EDIs) to a load whose electrical resistance can vary non-linearly and stochastically. The method is based on the use of one direct voltage generator (DVG) in the EDI, which carries out alternately an oscillatory charge of two CESs to the required voltage, as well as on the introduction of semiconductor switches into the charge circuit and discharge one of these CESs and the developed algorithms for switching them on, according to which bipolar discharge currents are formed alternately in the EDI load, regardless of the nature of the change in its electrical resistance. The frequency and duration of positive and negative discharge-pulse currents in the load can be the same or different, depending on the selected parameters of the elements of discharge circuits of the two CESs. The use of the developed method provides the formation of unipolar modes in the capacitors of each CES, which allows you to choose them for lower voltages, increase their life and reduce cost. In addition, with the same capacitance of the CESs, the total electric charge flowing in the load is practically zero after each even number of discharges. This significantly reduces the effect of electrochemical processes in the load, in particular the electrochemical destruction of the anode of the technological apparatus of the EDI, which inevitably occurs during the formation of unipolar pulse currents. The use of bipolar discharge currents in the EDI load also increases the stability of the discharge modes in the EDI due to the limitation of the duration of possible long aperiodic currents during the discharge of one of the CESs by the beginning of the counter current of the next discharge of the other CES.

The paper presents the advantages of protected insulated wires for medium-voltage (up to 35 kV) overhead power lines compared to the lines with traditional non-insulated wires. The mathematical model is developed and the computer calculations are realized for a 20 kV protected insulated wire with a steel-aluminum core. For such design, the distributions of the magnetic field and current density in three wires of overhead power line are analyzed, their resistance is determined taking into account the nonlinear properties of the steel core within the frequency range of 50–10000 Hz. This makes it possible to compute the electrical losses in the conductors of the power lines under the transient conditions and at high harmonics in the power network. References 8, figures 4.

A retrospective review of the development of the theory and practical structures of electric machines with a three-degree-of-freedom rotor (EMTR) at the Institute of Electrodynamics of the National Academy of Sciences of Ukraine. The applications of EMTR in surveillance, tracking and stabilization systems on moving objects are listed. The relevance of the development of such machines is shown. The disadvantages of the classical mathematical model of EMTR are noted and the need to develop a refined mathematical model due to the need to develop new technology, the emergence of new materials and electronic components, as well as the growth of computing capabilities. The two main known structures of EMTR are described and the advantages of the perspective structure chosen as the basic one are listed. The model of static three-dimensional magnetic field of EMTP and the associated dynamic model in the COMSOL Multiphisics environment are substantiated and constructed for the basic structure of EMTR. The connection between the magnetostatic problem and the rotor motion dynamics problem is ensured by the fact that the data of the calculated instantaneous characteristics are transmitted in the form of approximated dependences to the dynamic problem. In the mode of free rotation without losses, the dependences of the precession angle on time, amplitude and phase of the sinusoidal current of the control winding are calculated. High accuracy of observance of the direction of precession of the axis of the rotor at observance of the corresponding initial phase of sinusoidal current of a control winding is noted. The influence of rotation windings on the moment created by the control winding is investigated. References 3, figures 8.

A flux observer for induction motors which is adaptive to the active rotor resistance variations is presented. Due to the added fluxes overestimation in the observer structure, the global exponential stability properties of the current and flux vector components and active rotor resistance estimation are ensured under conditions of persistency of excitation. The proposed observer has a simpler structure compared to existing solutions with the global stability properties. The simulation results of the observer dynamic performance investigation confirm its effectiveness. It is shown that even if the conditions of persistency of excitation are not met, the active rotor resistance is estimated correctly; consequently, the designed observer can be implemented as an identification algorithm in self-commissioning systems of induction electric drives.

The controller of traction electric motors on permanent magnets for vehicles in which the power transistor converter is made on the modified IGBT modules with the improved characteristics is described in this work. The use of these modules, which are widely used today in semiconductor devices of modern dual-use technology, allows to reduce the size and weight of the converter, simplify the cooling system, increase efficiency and reliability of the semiconductor converter and electric drive in general due to harsh operating conditions. Bench tests of the experimental sample of the semiconductor converter and the microprocessor control system in various operating modes, including at the maximum load corresponding to real operating conditions are made and carried out. As a result of tests, it was determined that the technical characteristics of the controller meet the requirements of such devices. The created semiconductor controller on IGBT modified modules can be used to control motors on permanent magnets and motor wheels with a nominal power of 40-50 kW, maximum - 100 kW.

Published: August 2022

Although the number of randomized controlled trials (RCTs) published each year involving adult populations is steadily rising, the annual number of RCTs published involving pediatric populations has not changed since 2005. Barriers to the broader utilization of RCTs in pediatrics include a lower prevalence of disease, less available funding, and more complicated regulatory requirements. Although child health researchers have been successful in overcoming these barriers for isolated diseases such as pediatric cancer, common pediatric diseases are underrepresented in RCTs relative to their burden. This article proposes a strategy called High-Efficiency RandOmIzed Controlled (HEROIC) trials to increase RCTs focused on common diseases among hospitalized children. HEROIC trials are multicenter RCTs that pursue the rapid, low-cost accumulation of study participants with minimal burden for individual sites. Five key strategies distinguish HEROIC trials: (1) dispersed low-volume recruitment, in which a large number of sites (50–150 hospitals) enroll a small number of participants per site (2–10 participants per site), (2) incentivizing site leads with authorship, training, education credits, and modest financial support, (3) a focus on pragmatic questions that examine simple, widely used interventions, (4) the use of a single institutional review board, integrated consent, and other efficient solutions to regulatory requirements, and (5) scaling the HEROIC trial strategy to accomplish multiple trials simultaneously. HEROIC trials can boost RCT feasibility and volume to answer fundamental clinical questions and improve care for hospitalized children.
Longitudinal association between parental involvement and internet gaming disorder among Chinese adolescents: Consideration of future consequences as a mediator and peer victimization as a moderator
Authors: Dou Kai , Feng Xue-Ke , Wang Lin-Xin , Li Jian-Bin
Published: August 2022

Background and aims

Internet gaming disorder (IGD) in adolescents is a concerning issue. Positive parenting has been found to protect against adolescent IGD, but the underlying mechanisms await further investigation. As such, this study examined the longitudinal association between parental involvement (PI) – a specific type of positive parenting understudied in the literature of adolescent gaming disorder – and IGD. Moreover, this study also tested consideration of future consequences (CFC) as a mediator and peer victimization (PV) as a moderator.

Methods

A two-wave longitudinal research spanning 6 months apart was conducted. Participants were Chinese adolescents (final N = 434; 222 females; M
age = 14.44 years, SD = 1.56). They provided ratings on PI, PV, and IGD at Wave 1, and CFC-immediate, CFC-future, and IGD at Wave 2.

Results

Descriptive statistics showed that the prevalence rate of IGD was 10.81% and 9.45% at Waves 1 and 2, respectively. Moreover, results of moderated mediation model found that after controlling for Wave 1 IGD and covariates, Wave 1 PI was associated with Wave 2 IGD via preventing adolescents who had higher levels of PV from developing a tendence of CFC-immediate and via promoting adolescents who had lower levels of PV to develop a tendence of CFC-future.

Discussion and Conclusions

Altogether, these results suggest that facilitative ecological systems (e.g., positive parenting and good relationships with peers) and personal strengths (e.g., positive future orientation) jointly contribute to the mitigation of adolescent IGD.

In the proposed material, the author's team, as in some other similar articles, continues to analyze the topic of redundancy and the professionally applied nature of the training of athletes and athletes. The relevance of such an analysis is based on numerous precedents and attempts to pass one off as another, building a bridge on this supposedly natural and continuous transition from a sports career to career growth in other professional areas of labor and military practice that are not directly related to the sphere of physical culture and sports. Which often leads to sad consequences.
The demonstration of the fundamental differences between redundancy and the professionally applied nature of physical culture and sports training with examples from the field of boxing, taekwondo, practical shooting clearly confirms the correctness of the argumentation and conclusions of the authors of the article. At the same time, the material of the article indicates the possibility and necessity of developing this topic for the preparation of athletes and athletes not only for military or service, but also for civilian labor professional activity. Consequently, the topic chosen by the author's team has a continuation in the field of development of professionally applied sections of physical culture and sports training in non-core domestic universities.

RESUMO Este artigo aborda aspectos da trajetória pessoal e escolar de um aluno da EJA, em situação de analfabetismo. Para tratar desses aspectos, procuramos responder esta pergunta: como se configura o patrimônio vivencial de um educando de 20 anos de idade, na atividade de alfabetização, em contexto escolar? Buscando respondê-la, escolhemos, como fundamentação teórica, as noções de perezhivanie (VYGOSTKY, 2010; REY, 2016; VERESOV, 2016), agência (NININ; MAGALHÃES, 2016), repertório (BLOMMAERT; BACKUS, 2012; BUSCH, 2017; GUIMARÃES; MOITA LOPES, 2017) e patrimônio (MOLL et al., 1992; ESTEBAN-GUITART; MOLL, 2014; LIBERALI; MEGALE, 2020). A metodologia de pesquisa é qualitativo-interpretativista, na forma de estudo de caso. Os procedimentos de geração de dados são: uma entrevista semiestruturada e conversas entre o educando e a professora-pesquisadora. Tais dados, interpretados à luz do referido arcabouço teórico, sugerem que há uma transformação na agência do sujeito de pesquisa. Essa transformação é reputada não só a fatores internos, mas também a fatores externos, como a relação com a professora alfabetizadora e com a escola onde o educando estuda. Essas mudanças constituem seu patrimônio vivencial.
DISCURSOS SOBRE A CRIMINALIZAÇÃO DA HOMOFOBIA E DA TRANSFOBIA NO PORTAL DE NOTÍCIAS O ANTAGONISTA

Published: August 2022

RESUMO Neste artigo, apresentamos uma amostra dos resultados da pesquisa Facetas discursivas em torno da criminalização da homofobia e da transfobia (TAVARES, 2019), cujo objetivo foi analisar o modo como a decisão do Supremo Tribunal Federal brasileiro em tipificar como crime a homofobia e a transfobia foi mobilizado em uma cadeia de eventos discursivos publicada pelo portal de notícias O Antagonista. Com base em pressupostos teóricos dos estudos críticos do discurso, e utilizando a linguagem de descrição do sistema de transitividade, tomamos três textos do corpus para mostrar como os eventos e atores sociais envolvidos são representados, quais discursos tais textos atualizam e que efeitos de sentido potenciais têm. Os resultados apontam que a representação tematiza o possível descontentamento de religiosos e apaga os benefícios à comunidade LGBTQIA+. Tal apagamento é utilizado ideologicamente para sustentar a LGBTfobia como uma estrutura em que vidas LGBTQIA+ são desimportantes ou não merecedoras de proteções legais.

ABSTRACT This study aimed to identify the Staphylococcus species responsible for bovine mastitis in dairy herds in northern Brazil, to investigate the capacity of biofilm production, and to analyze the association of biofilm production with multiresistance and intensity of California Mastitis Tests (CMT) reactions that can make treatment more difficult and cause misdiagnoses, respectively. Milk samples were collected from 23 dairy farms located in five municipalities in the state of Acre. A total of 339 crossbred cows were tested by CMT, with 109 animals (229 udder ceilings) reacting to the test. After bacterial isolation in blood agar, the catalase-positive and gram-positive cocci were submitted for identification by MALDI-TOF MS. Of 103 strains identified as staphylococci, Staphylococcus chromogenes (58.3%) and Staphylococcus aureus (19.4%) were the most prevalent species. Biofilm production was quantitatively evaluated using a microplate adherence test. Among the Staphylococcus strains, 71.8% were biofilm producers. Most strains of S. chromogenes (68.3%) had the capacity to produce biofilms, ranging from weak (43.3%), moderate (13.3%), and strong (11.7%) producers. Among S. aureus strains, 50% were non-biofilm producers, and none were strong producers. Our data showed an association between biofilm production capacity and multidrug resistance. In addition, there was a reduction in the response to the CMT test, which can mask the diagnosis.

ABSTRACT Infection caused by Aeromonas brings great harm to fish farming. Among the factors associated with bacterial pathogenesis, iron uptake can contribute to the survival and virulence of bacteria within hosts. The aim of this study was to check the presence of genes related to iron uptake in Aeromonas hydrophila deriving from aquatic organisms in the São Francisco Valley and associate the presence of these genes with the ability to grow in media containing different concentrations of iron. The DNAs of 41 isolates were extracted and used in PCRs to verify the presence of the Fur, AmoA and pvcAB genes related to iron uptake. The growth of the isolates belonging to different genetic profiles was verified in culture media containing different iron concentrations. Two isolates were positive for the presence of the Fur gene, seven for the AmoA gene and two for the pvcAB gene. The growth test showed that the low availability of iron did not interfere in the growth of the isolates, nor in the isolate that did not contain any of the genes evaluated in this study, suggesting that the iron uptake’s mechanisms of the tested isolates may be related to other genes and proteins.

ABSTRACT The aim of this study was to identify the prevalence and the main risk factors related to the transmission of bovine cysticercosis based on tracking animals sent for slaughter and coming from properties located in the micro-region of Uberlândia, Minas Gerais, Brazil. The properties were previously evaluated for the occurrence of cysticercosis during post-mortem inspection in the 12 months prior to the beginning of the research, and those with animals with bovine cysticercosis found at least once during this period were considered positive. A cross-sectional study was carried out on 87 properties, from which 1024 bovine serum samples were collected. Indirect ELISA performed serological diagnosis and Immunoblot confirmed positive sera. The prevalence found in this study was 5.1% (95% CI = 3.74-6.42). The risk factors identified were cattle origin (RC = 4.9), grazing (RC = 6.4) and sewage destination on the property (RC = 3.6). These environmental factors suggest that sanitation control measures and the restriction of pastures beyond the property boundary can help prevent disease in the study area. A control system based on risk analysis was discussed and proposed as a strategy to control bovine cysticercosis in the Triângulo Mineiro region and other regions of the country.

ABSTRACT The objective of this study was to develop a novel subgingival sustained-release system for local delivery of bioactive minocycline hydrochloride for periodontal disease treatment in dogs. The system incorporated the Minocycline hydrochloride-Calcium-Dextran sulfate sodium into a thermoresponsive Pluronic F127 hydrogel. Minocycline hydrochloride was sustained release from the system for up to 10 days and the release kinetics fit the power law model. The release medium had a significant statistical difference in antimicrobial activity to Aggregatibacter actinomycetemcomitans. The results showed the system was a promising subgingival sustained-release minocycline hydrochloride delivery system for periodontal disease treatment in dogs.

ABSTRACT The pineal is a neuroendocrine gland responsible for the synthesis and release of melatonin. It is present in the brain of vertebrates, but its morphology and location vary considerably among species. For the species Alouatta belzebul, although some anatomical aspects of the nervous system have been described, there is no information on the morphology and histological composition of this gland. Thus, the present study aimed to describe the morphological, morphometric, and histological aspects of the pineal of Alouatta belzebul. Seven adult specimens were dissected from which the location of the gland in relation to the surrounding brain structures was described, and its length and width were measured. Histological slides were then prepared and stained using hematoxylin-eosin and PAS techniques. It was observed that the pineal of Alouatta belzebul is located superior and cranial to the cerebellum, superior to the superior colliculi and below the splenium of the corpus callosum and was classified as sub-callosal. It had an average length of 2.6mm and an average width of 1.14mm. Histologically the gland is composed of irregular strands of pinealocytes and gliocytes. The pinealocytes showed pigments similar to melanin.

ABSTRACT The objective was to study the productive and biological traits of young cattle of the Kalmyk breed and its crosses. The experiment was conducted on 4 groups of steers, 10 heads each, at OAO Shurupovskoe, Frolovsky District, Volgograd Region. The experimental steers were kept in rooms separately in groups on a deep bed of straw and had free access to walking yards with mounds. The hemoglobin content and the numbers of erythrocytes and leukocytes were determined on a Medonic CA 530 hematological analyzer. The total protein in blood serum and protein fractions were found on an automatic biochemical analyzer Stat Faks 1904. The digital experimental data were processed by the variation statistics method in terms of the significance of the compared parameters using the Student's test accepted in biology and animal science. The study evidenced that the contents of morphological elements and proteins in blood reflected the metabolism and potential for crossbred steers to gain muscle mass.

ABSTRACT The present study was conducted to investigate the effect of season and housing system on hematochemical attributes of rabbits in Southern Punjab, Pakistan. Adult healthy rabbits (n=30) were divided into two groups of equal size (n=15). Group I was housed in a modern cage system and group II in traditional colony system for a period of one year. Blood samples of rabbits from both groups were collected in the summer and the winter seasons and analyzed for various hematochemical attributes. Hematochemical attributes including red blood cell (RBC) count, hematocrit (HCT), mean corpuscular volume (MCV), total white blood cell (WBC) count, mixed cells (MID), granulocytes (GRA), glucose and alanine aminotransferase (ALT) were lowered significantly (P<0.05) in the summer in relation to the winter, while mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), creatinine, and cholesterol level were significantly (P<0.05) higher during the summer season. Biochemical attributes as cholesterol, triglycerides and globulin were significantly (P<0.05) lower in the caged rabbits. In conclusion, the summer season caused a significant decrease in most of the hematochemical attributes whereas housing system did not affect most of the hematochemical attributes of the rabbits under the climatic conditions of Southern Punjab, Pakistan.
