A Weighted Poisson Distribution for Underdispersed Count Data
Authors: Gelin Louzayadio Chedly , Onesime Malouata Rodnellin , Koukouatikissa Michel Diafouka
Published: June 2021

In this paper, we present a new weighted Poisson distribution for modeling underdispersed count data. Weighted Poisson distribution occurs naturally in contexts where the probability that a particular observation of Poisson variable enters the sample gets multiplied by some non-negative weight function. Suppose a realization y of Y a Poisson random variable enters the investigator’s record with probability proportional to w(y): Clearly, the recorded y is not an observation on Y, but on the random variable Yw, which is said to be the weighted version of Y. This distribution a two-parameter is from the exponential family, it includes and generalizes the Poisson distribution by weighting. It is a discrete distribution that is more flexible than other weighted Poisson distributions that have been proposed for modeling underdispersed count data, for example, the extended Poisson distribution (Dimitrov and Kolev, 2000). We present some moment properties and we estimate its parameters. One classical example is considered to compare the fits of this new distribution with the extended Poisson distribution.

Published: June 2021

In academia, the study of the movement of water in the ground has been widespread since the last century. The same can be determined using the Richards equation. This is a nonlinear parabolic partial differential equation that requires parameters to generate the results of the problem. Some authors have proposed equations that represent the relationship between volumetric moisture and soil water potential, such as Haverkamp and van Genuchten. As main objective of this work, the inverse modeling was implemented to obtain the Richards equation parameters, applying the Luus-Jaakola method. To verify the mathematical model, a sensitivity analysis was performed, which allowed the observation of the effect that each parameter has on the output data, implying a linear dependence. The results produced proved to be satisfactory for the problem analyzed in our research.
A Numerical Study of a Rotor Induced Flow Based on a Finite-State Dynamic Wake Model.
Authors: A. Ferreira L. G. , Júnior C. C. Pagani , Gennaro E. M. , Junior C. De Marqui
Published: June 2021

A Helicopter rotor undergoes unsteady aerodynamic loads ruled by the aeroelastic coupling between the elastic blades and the dynamic wake induced by rotary wings. Modeling the dynamic interaction between the structural and aerodynamic fields is a key point to understand aeroelastic phenomena associated with rotor stability, flow induced vibration and noise generation, among others. In this study, we address the Generalized Dynamic Wake Model, which describes the inflow velocity field at the rotor disk as a superposition  of a finite number of induced flow states. It is a mature model that has been validated based on experimental data and numerically investigated from an eigenvalue problem formulation, whose eigenvalues and eigenvectors provide a deeper insight on the dynamic wake behavior. The paper extends the results presented in the literature to date in order to support physical interpretation of inflow states drawn from the finite-state wake model for flight conditions varying from hover to edgewise flight. The discussion of the wake model mathematical formulation is also oriented towards practical engineering applications to fill a gap in the literature.

Feminismo andaluz: acercamiento a una nueva línea de pensamiento feminista
Authors: Chacón-Chamorro Victoria , Terrón-Caro Teresa
Published: June 2021

El feminismo está presenciando un auge a nivel internacional y, con él, los diferentes feminismos, en plural, junto a la reivindicación de los conceptos de interseccionalidad y transversalidad. Paralelamente, también ha resurgido la defensa de las identidades particulares frente al mito de la modernidad desde los feminismos periféricos. A este contexto, hay que sumarle las consecuencias negativas de la crisis iniciada en 2008 para entender la (re)aparición del feminismo andaluz como respuesta a la doble discriminación sufrida por las mujeres andaluzas, por ser mujeres y andaluzas, que, al sumarle otras variables, podríamos hablar de una discriminación múltiple, por ejemplo, por también ser de clase trabajadora empobrecida. Con el presente artículo, a través de una revisión bibliográfica, pretendemos analizar cómo esta nueva línea de pensamiento feminista se presenta como orgullo y resistencia, siendo sus bases de acción y resignificación el territorio, la identidad y la condición de mujer.
Legal succession of property-related obligations in administrative
enforcement proceedings
Authors: Dalkowska Anna
Published: June 2021

Legal succession of property-related obligations in administrative enforcement proceedings is a key
issue for the protection of the public interest. Coercive enforcement measures directed against
the obliged entity, in accordance with the content of the enforceable title, serve the purpose of
compulsory performance of the obligation. A change or transformation of the addressee of an obligation
while maintaining the identity of the enforcement case and the content of the enforcement
relationship determines the legal situation of the parties to the enforcement proceedings, i.e. the
obliged entity, its successor, the public-law creditor, the enforcement authorities and other participants
to the proceedings. The property-related nature of the obligation implies the consequences
of the enforcement transformation in a specific way, i.e. both at the procedural and substantive-law
levels, leading to a joint and several liability of the obliged parties and their co-participation in enforcement
proceedings. The statutory regulation laid down in Article 28a of the Act on Enforcement
Proceedings in Administration is not sufficient, therefore, legal scholars’ writings, court rulings and
practice play an important role this matter.

IDENTIFICATION OF THE MINIMUM LEVEL OF KNOWLEDGE ON SOCIAL INSURANCE
Authors: Marczak Robert
Published: June 2021

The Polish social insurance system is a part of the social security scheme. The Constitution of the Republic of Poland imposes on the state an obligation to create such system and to fulfill social security guarantees for every citizen. Participation in the social insurance system, and thus insurance coverage in the field of the consequences of social risks, is strictly dependent on the fact of performing a gainful activity on the principles set out in the social insurance act (among others: work under a contract of employment or under a civil law contract and conducting business). The legality of employment and the employer fairness on the one hand, and the effectiveness of control authorities of state institutions on the other hand, are two driving engines of the insurance guarantee. Responsibility for providing such insurance protection lies between the institutional activities of the state and the individual foresight of the citizen. It is on his/her side that knowledge about social insurance plays a very important role as an element of risk awareness. The act on the social insurance system imposes on the Polish executive institution in the area of social insurance (the Polish social insurance institution, ZUS) the obligation to popularize this knowledge. The purpose of the article is the attempt to indicate the scope of a minimum knowledge of social insurance, which will allow a citizen to make a conscious participation in the system, i.e. effective protection against the results of the possible risks.

WWII VICISSITUDES OF THE INSIGNIA OF KING
AUGUSTUS III
Authors: Kudelski Jarosław Robert
Published: June 2021

During WW II, numerous precious art works
from Polish public and private collections were looted,
displaced and taken out of Poland. In view of the value of
some of those pieces, the invaders’ authorities decided
to have them transferred to German museums, and this is
what happened to the coronation insignia of King Augustus
III and his spouse Maria Josepha. German officials took over
the regalia which were property of the National Museum
in Warsaw already in 1939. Some time after, they were
transferred to Cracow, the capital of the General Government.
Several months later the insignia returned to Warsaw. In
1941, Dr Hans Lammers, Chief of the Reich Chancellery, requested
them. On Adolf Hitler’s decision they were to be
transferred to Dresden’s Grünes Gewölbe; in order to be
transported there they were taken from Warsaw in 1942.
By the end of the war, they were evacuated to a repository
of artworks in the cellars of the Königstein Fortress. After
WW II had ended, they were relocated, together with other
cultural goods, to Moscow. It was only in 1960 that the
Soviet regime returned the precious regalia to Poland.

Published: June 2021

A cada safra, milhões de litros de etanol e milhares de toneladas de açúcar são exportados pelo setor sucroalcooleiro brasileiro. A ociosidade e sobrecarga de trabalho na produção devido à falta de previsibilidade sobre a quantidade da matéria-prima disponível são alguns problemas no setor. Este trabalho tem como objetivo construir indicadores operacionais, utilizando como base a distribuição dos resíduos do modelo SARIMA (Seasonal Autoregressive Integrated Moving Average), para informar a probabilidade de redução na produção de cana-de-açúcar. A base de dados foi retirada dos resultados trimestrais publicados pelo Grupo São Martinho. Os resultados obtidos evidenciam o potencial do modelo proposto para a tomada de decisão.
Threshold-based Wireless-based NOMA Systems over Log-Normal Channels: Ergodic Outage Probability of Joint Time Allocation and Power Splitting Schemes
Authors: Thien Van Hoang , Van Quyet-Nguyen , Le Danh Hong , Sevcik Lukas , Hoang Duy Nguyen , Nguyen Hoang-Sy , Voznak Miroslav
Published: June 2021

Due to the development of state-of-the-art fifth-generation communication (5G) and Internet-of-Things (IoT), the demands for capacity and throughput of wireless networks have increased significantly. As a promising solution for this, a radio access technique, namely, non-orthogonal multiple access (NOMA) has been investigated. Particularly, in this paper, we analyse the system performance of a joint time allocation and power splitting (JTAPS) protocol for NOMA-based energy harvesting (EH) wireless networks over indoor scenarios, which we modelled with log-normal fading channels. Accordingly, for the performance analysis of such networks, the analytical expression of a metric so-called “ergodic outage probability” was derived. Then, thanks to Monte Carlo simulations done in Matlab, we are able to see how different EH power splitting (PS) and EH time switching (TS) factors influence the ergodic outage probability. Last, but not least, we plot the simulation results along with the theoretical results for comparison studies.

Background: Vulvovaginal candidiasis (VVC) is the most frequent fungal disorder in healthy and normal women. Objectives: The aim of this study was to evaluate the in vitro antifungal susceptibility of clinical isolates Candida albicans and Candida glabrata, the two most common candida species in Iranian patients with VVC. Methods: One hundred and eight clinical isolates of candida, including; C. albicans (n = 77) and C. glabrata: (n = 31) were isolated from the 108 patients with VVC. The in vitro activity of caspofungin (CAS), amphotericin B (AMB), voriconazole (VRC), itraconazole (ITC), fluconazole (FLC), and nystatin (NYS) were determined according to the CLSI M27-A3 and CLSI M27-S4. Results: Our results were shown 8 (25.8 %) and 6 (7.8 %) C. glabrata and C. albicans isolates resistance to FLU, respectively. Furthermore, resistance to VRC and ITC were observed in 8.4%, and 3.7% of all isolates, and six isolates (5.6%) had intermediate MIC to CAS. Conclusions: We reported 8 (25.8 %) and 6 (7.8 %) C. glabrata and C. albicans isolates resistance to FLU, respectively. Furthermore, resistance to VRC and ITC were observed in 8.4% and 3.7% of all isolates, respectively.
Evaluation of Given Dose Accuracy in Radiation Therapy of Patient with Breast Cancer Using Diode In Vivo Dosimetry
Authors: Rasouli Farah Sepideh , Mostaar Ahmad , Ameri Ahmad , Mafi Ahmad R , Anbiaee Robab
Published: June 2021

Background: The main goal of radiation therapy is to deliver the highest dose to the tumor and at the same time the lowest dose to the surrounding normal tissue. In vivo dosimetry is a quality control procedure that, instead of controlling the components separately, directly examines the dose reached to the tumor area. Objectives: In this study, the entrance, exit, and middle dose of the breast and supraclavicular area of patients with breast cancer under radiation therapy were measured and compared with calculations. Methods: In this experimental study, the entrance and exit doses of 33 patients with breast tumors treated with 6 MV and 18MV photons were measured simultaneously. The measurement was done, using p-type diodes after calibration and, then, the midpoint dose was calculated, using the transfer method and arithmetic mean method. Also, the entrance dose, exit dose, and midline dose measured with dosimeter were compared with the calculated values in the treatment planning system. Results: There was no significant difference between calculated and measured doses in the entrance, exit, and midline point in breast regions (P > 0.05), but in the supraclavicular region, a challenge was observed. The difference in entrance and midline point between calculation and measurement is not significant based on the transfer method, but there is a significant error based on the arithmetic mean method (P < 0.05). Conclusions: In vivo dosimetry by measured real given dose to the patient can perform a basic role in the quality control of the radiotherapy department. It seems in the entrance dose, the relative error is smaller but due to the smaller value of exit dose, the relative error in small values is more apparent.
Prolagus Pomel, 1853 (Lagomorpha, Mammalia) in the framework of the Pliocene faunal rearrangements in central Europe
Authors: ČERMÁK Stanislav , ANGELONE Chiara , MONCUNILL-SOLÉ Blanca
Published: June 2021

Pliocene occurrences of Prolagus Pomel, 1853 in central Europe represent anomalies out of the peri-Mediterranean area, at that time the core distribution of the genus. Though known for several decades, those materials never underwent a general revision. The detailed analysis and comparison of all available materials performed here revealed two phenotypic entities: 1) Prolagus bilobus Heller, 1936 (Gundersheim localities, Raciszyn 1), for which were defined additional diagnostic characters and ontogenetic patterns of variation (d3/p3 and mandible); and 2) Prolagus sp. (Beremend 26/39), probably a new species. All the available occurrences are dated to MN15b. The morphological trends towards the reduction of p3 entoconid and of enamel folding evidenced in Pliocene Prolagus of western Europe cannot be recognized in coeval central European forms. Evidently, P. bilobus and Prolagus sp. do not pertain to the western European clade, whose separation is known since the early late Miocene. We hypothesize that at least P. bilobus originated from a dispersal of Prolagus from south-eastern regions of Europe rather than from an autochthonous speciation of isolated populations left as a relict after the southward displacement of Prolagus distribution area. The dispersal is likely to be related to the Pliocene global environmental changes during which extensive faunal rearrangements took place in Europe, in particular to those near the early/late Pliocene boundary.
Onasemnogene Abeparvovec (AVXS-101) for the Treatment of Spinal Muscular Atrophy
Authors: Naveed Aimen , Calderon Hillary
Published: June 2021

Spinal muscular atrophy (SMA) is a debilitating disorder characterized by degeneration of large motor neurons. It is a heterogeneous group of disorders caused by a homozygous deletion in the survival motor neuron (SMN) gene on chromosome 5, resulting in a SMN protein deficiency. Small amounts of SMN protein are also produced by the SMN2 gene, which that differs from SMN1 by a single nucleotide. Spinal muscular atrophy types and phenotypic severity depend on the number of variations of the SMN2 gene and the amount of SMN2 protein produced. Because the SMN protein deficiency is the root cause of the disease, treatment strategies for SMA revolve around increasing SMN protein production. Nusinersen (Spinraza, Biogen, Cambridge, MA) was the only treatment option available for SMA until the FDA approved onasemnogene abeparvovec-xioi (Zolgensma, AveXis Inc, Bannockburn, IL), a one-time–administered adeno-associated viral vector–based gene therapy that delivers the SMN gene to the motor neuron cells. Data from clinical studies show significant improvement in motor milestone achievements and ventilator-free survival but are limited by approximately 5 years' worth of results. This one-time intravenous injection of this new gene therapy also bears a hefty price tag; however, it may be more cost effective in the long run versus the multiple intrathecal administrations needed with nusinersen. Drug access and use are hindered by drug cost, payer reimbursement issues, and lack of long-term data from clinical studies. Questions also remain regarding the safety and efficacy of repeated drug administration for patients with advanced disease.

Published: June 2021

While serious illness is a crisis in the life course of any human being, it harmonizes particularly poorly with traditional notions of masculinity. Statistically, more men than women get cancer, but women seem more likely to communicate about their emotions and experiences of illness in public. In this article, we examine the connection between cancer narratives, war and combat metaphors and hegemonic masculinity based on six recent Danish autobiographies written by men about their experience of having cancer. Based within critical masculinity theories and metaphor theory, we examine how the autobiographies apply and develop traditional combat metaphors and we argue that new narratives and (counter) metaphors are developed and that they influence both the experience of illness and the understanding of masculinity.
Do Forms of Knowledge Production Circulate?
Authors: Isola Nicolás José
Published: June 2021

Forms of knowledge production adopted by academics in a given national space do not emerge without the right circumstances. Student circulation has a bearing on knowledge import processes. Opening with an overview of the field of Argentinian anthropology in the 1970s and 1980s, this article looks at some of the consequences of the international circulation of Argentinian students through the Social Anthropology Master’s and PhD Programs at the National Museum of the Federal University of Rio de Janeiro (PPGAS-MN/UFRJ) from the late 1980s to the present. Based on documents in the PPGAS-MN archives, interviews with lecturers and former students and a review of PPGAS-MN and Argentinian university syllabi, this article: (i) provides a historical description of the agreement between institutions that has facilitated this flow; (ii) describes how this circulation has given these students a new perspective on the ethnographic approach and on classical anthropology; and (iii) describes how, from a student viewpoint, this shift has altered their way of thinking about social anthropology research and given them a new habitus. The results hint at a new approach to classical anthropology and the use of ethnographic data. There were three main drivers: (i) PPGAS-MN lecturers’ emphasis on the relevance of empirical data and the primacy of theory prevailing in Argentina; (ii) the renewed deep reading of classic ethnographical texts; and (iii) the development of a new habitus as a result of socialisation in the ensuing social space.

A sociological imagination for a clumsy world: François Dépelteau’s relational sociology
Authors: Selg Peeter
Published: June 2021

In this paper I introduce the special section on the work of the late Francois Dépelteau (1963-2018), by analyzing an essential tension within the relational sociology which I call the division between “clumsy” and “elegant” relationalism. “Clumsy” relationalism as exemplified most uncompromisingly by Francois is in a way an extreme perspective on social research, prescribing a certain “obsession” with change and unfolding of reality, rather than its stability or firm foundation. As Francois has put it in one of his last published works: “Everything is changing all the time, including ourselves. This is hard to accept since we are looking for some sort of stability often to reassure ourselves.” I ask why should we accept this perspective rather than continue with reassuring ourselves. I also point out that both “elegant” and “clumsy” relationalisms are useful for social research, but that the latter is increasingly pertinent for contemporary world inhabited by “wicked” social problems that have no elegant solutions or even definitions. I also analyse in more detail Francois’s critique of Pierre Bourdieu’s sociology that is the most eminent example of “elegant” relationalism, and the furthering of “clumsy” relational sociology in the contributions to the special section by Nick Crossley and Jean-Sebastien Guy.

Published: June 2021

Chemotherapy resistance is a critical barrier in cancer treatment. Metabolic adaptations have been shown to fuel therapy resistance; however, little is known regarding the generality of these changes and whether specific therapies elicit unique metabolic alterations. Using a combination of metabolomics, transcriptomics, and functional genomics, we show that two anthracyclines, doxorubicin and epirubicin, elicit distinct primary metabolic vulnerabilities in human breast cancer cells. Doxorubicin-resistant cells rely on glutamine to drive oxidative phosphorylation andde novoglutathione synthesis, while epirubicin-resistant cells display markedly increased bioenergetic capacity and mitochondrial ATP production. The dependence on these distinct metabolic adaptations is revealed by the increased sensitivity of doxorubicin-resistant cells and tumor xenografts to buthionine sulfoximine (BSO), a drug that interferes with glutathione synthesis, compared with epirubicin-resistant counterparts that are more sensitive to the biguanide phenformin. Overall, our work reveals that metabolic adaptations can vary with therapeutics and that these metabolic dependencies can be exploited as a targeted approach to treat chemotherapy-resistant breast cancer.
A novel decoy strategy for polymyxin resistance in Acinetobacter baumannii
Authors: Park Jaeeun , Kim Misung , Shin Bora , Kang Mingyeong , Yang Jihye , Lee Tae Kwon , Park Woojun
Published: June 2021

Modification of the outer membrane charge by a polymyxin B (PMB)-induced PmrAB two-component system appears to be a dominant phenomenon in PMB-resistant Acinetobacter baumannii. PMB-resistant variants and many clinical isolates also appeared to produce outer membrane vesicles (OMVs). Genomic, transcriptomic, and proteomic analyses revealed that upregulation of the pmr operon and decreased membrane-linkage proteins (OmpA, OmpW, and BamE) are linked to overproduction of OMVs, which also promoted enhanced biofilm formation. The addition of OMVs from PMB-resistant variants into the cultures of PMB-susceptible A. baumannii and the clinical isolates protected these susceptible bacteria from PMB. Taxonomic profiling of in vitro human gut microbiomes under anaerobic conditions demonstrated that OMVs completely protected the microbial community against PMB treatment. A Galleria mellonella-infection model with PMB treatment showed that OMVs increased the mortality rate of larvae by protecting A. baumannii from PMB. Taken together, OMVs released from A. baumannii functioned as decoys against PMB.
Identification of a three-gene-based prognostic model in multiple myeloma using bioinformatics analysis
Authors: Pan Ying , Meng Ye , Zhai Zhimin , Xiong Shudao
Published: June 2021

Background

Multiple myeloma (MM), the second most hematological malignancy, has high incidence and remains incurable till now. The pathogenesis of MM is poorly understood. This study aimed to identify novel prognostic model for MM on gene expression profiles.

Methods

Gene expression datas of MM (GSE6477, GSE136337) were downloaded from Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) in GSE6477 between case samples and normal control samples were screened by the limma package. Meanwhile, enrichment analysis was conducted, and a protein-protein interaction (PPI) network of these DEGs was established by STRING and cytoscape software. Co-expression modules of genes were built by Weighted Correlation Network Analysis (WGCNA). Key genes were identified both from hub genes and the DEGs. Univariate and multivariate Cox congression were performed to screen independent prognostic genes to construct a predictive model. The predictive power of the model was evaluated by Kaplan–Meier curve and time-dependent receiver operating characteristic (ROC) curves. Finally, univariate and multivariate Cox regression analyse were used to investigate whether the prognostic model could be independent of other clinical parameters.

Results

GSE6477, including 101 case and 15 normal control, were screened as the datasets. A total of 178 DEGs were identified, including 59 up-regulated and 119 down-regulated genes. In WGCNA analysis, module black and module purple were the most relevant modules with cancer traits, and 92 hub genes in these two modules were selected for further analysis. Next, 47 genes were chosen both from the DEGs and hub genes as key genes. Three genes (LYVE1, RNASE1, and RNASE2) were finally screened by univariate and multivariate Cox regression analyses and used to construct a risk model. In addition, the three-gene prognostic model revealed independent and accurate prognostic capacity in relation to other clinical parameters for MM patients.

Conclusion

Agriculture continues to be the most important sector of the Indian economy and agriculture is a more or less a compulsion for livelihood of millions of farmers. Now-a-days, Indian agriculture faces several problems such as low yield, inconsistent product quality, lack of knowledge about domestic as well as international markets and poor access to diversified agriculture information. Farmers need location specific information at the time of all the cultivation stages of agriculture in their local language. To meet out these problems, adoption of digital technology is one which improves the information transmission speed, networking, communication at their doorsteps and provides quality information in an understandable way to the farmers. Digital communication technologies when applied to condition in rural areas can help to improve communication by increasing the participation and also disseminating various information to increase their knowledge and skills. Digital efforts are being tried out by different Governments for the betterment of the agricultural sector and farmers. The digital technology in India is now at the crucial stage. Various digital initiatives such as Digital green, mobile technology, e-Choupal, precision farming, agricultural drones etc. should be promoted at large scale to improve the adoption of new technology by farmers. By this we can solve the problems like low yield, inconsistent product quality, lack of knowledge about domestic as well as international markets and poor access to diversified agriculture information.

Increased human populations and the resulting encroachment of related lands with poaching of tigers and their key prey threaten the survival of tigers across their range. Mere collection of huge data on ecology does not promote the protection of carnivores but it mainly depends on public co-operation and awareness. The public attitude towards carnivores (Panthera tigris tigris) is vital because fear pervades among the local inhabitants. Our target population consisted of all adults inhabitants. We sampled arbitrarily founded on geographic area. We guessed that the best data collection method would involve sampling at home of the residents by personal interview with the questionnaires due to huge illiteracy of the inhabitants. Proceeding this way was time-consuming but proved to increase the quality of responses. We studied villagers’ mind-set and collected information on public awareness, feelings and frequency of sightings related to the tigers. They were conscious of its existence and aware of its ecological values to conserve Sunderbans also. To better understand the social factors affecting large carnivore conservation, we surveyed the tiger-affected people, the relatives of the people killed by tigers and the common villagers in the village of Samser nagar of Sunderbans, West Bengal, in India. People living in this area are heavily dependent on forest for their livelihood. They collect honey and catch crabs and fish seedlings from the jungle. Nowadays, many tourists came to see flora and fauna and the eternal beauty of Sunderbans. Many people depend their livelihood on tourism. These social factors make them to think to save Sunderbans. If Sunderbans is destroyed in near future, then they will suffer economically. A financial constraint of the inhabitants to protect the human lives and cattle from the attack of tigers was revealed by choosing the category willing to conserve but not afforded to pay. This study was the first assessment of public responsiveness and exposed the basic data for understanding Bengal tigers in the area of Samsher nagar of Sunderbans.

The study was carried out to ascertain ways to increase protein for the teeming population of Nigerians. The specific objectives were to determine the growth performance of rabbits fed on rabbit feed and combination of agricultural by-product with forages and compare their feed utilization. It investigated the growth performances of rabbits; (Orynctolagus cuniculus) fed diverse ration (types A and B) in captivity for 12 weeks. A total of eighteen (18) weaner rabbits with an average initial weight of 350g – 370g and between 5 and 6 weeks old, were allotted into two treatments. Each treatment had three rabbits and three replicate in a completely randomized design. Rabbits in treatment one (A) were fed rabbit feed while the treatment two (B) were fed forage and diverse foodstuffs. Proximate analysis of these food ration types A and B showed that the ration type B was high in crude protein (23.88%), carbohydrate (53.29%) and fat (8.60%) and ration type A had the lowest crude protein (20.76%), carbohydrate, (52.49%) and fat (3.15%). Studies on the indices of ration utilization and growth performances showed that feed intake was highest in rabbit fed ration type A (94.28g) and lowest in ration B (90.98g). The diverse ration types although portrayed good weight gain, the highest was in rabbit fed ration type B (760.00g) and lowest in ration A (681.00g) and ration type B was significantly (p<0.05) different from ration A. The percentage weight gain and specific growth rate were highest in ration type B (210.50%), (4.097) and lowest in ration A (189.10%), (3.841). The best food conversion ratio was recorded for the rabbit fed ration type B (10.07g) and least in ration A (11.64g) and ration type A was significantly (p<0.05) different from ration B. Digestibility was highest in rabbit fed Ration A (93.33g) and lowest in ration B (92.67g) and were significantly different (p<0.05) from each other. The protein intake of ration B (21.73) was higher than those of ration A (19.57). The result also showed that the protein efficiency ratio of ration type A and B was not significantly different (p>0.05) from each other. Looking at the proximate composition of the diverse rations and indices of ration utilization, ration type B portrayed optimal nutrient content for rabbit growth.

At present, research in the field of the brain does not cease to surprise us with new facts and discoveries that no one could have suspected about 30 years ago. But it was at the time when it became clear that the cerebral neurons are not the only cells that can respond to changes in the external environment. A real scientific boom began to study a heterogeneous group called glia. And scientists are paying close attention to the largest of them – astrocytes. Understanding the importance of astrocytes in the mechanisms of repair and damage to brain cells in various forms of CNS pathology determines the possibility of targeted search for drugs that affect the rate of development of reactive astrogliosis in response to various brain injuries. At the same time, pharmacological modulation of activated astrocytes and other components of glia can be an integral part of the therapy of neurological diseases.
