Authors: Oruene I.S. , Mutembei H.M. , Kipyegon A.N. , Rekwot P.I. 
Published: May 2024

The testis in male domestic animals has two primary functions: spermatogenesis and steroidogenesis, coordinated by testicular cells under GnRH control. This study examined the features of the testes of the bucks of the West African dwarf breed to assess the effects of additional GnRH-stimulated levels of FSH, LH, T, and estradiol from 3 to 12 months of age. Twelve 3-month-old bucks were divided in a random manner into GnRH-treated (n = 6) and control (n = 6) groups. Monthly, bucks were weighed, their testicular diameter measured, and two blood samples taken (n = 12) at a 1-hour interval to establish peripheral concentrations. The GnRH-treated group received 0.5μg/ kg of GnRH intramuscularly the next day, while the control group received saline subcutaneously. Blood samples were taken 1 and 2 hours later to establish GnRH-stimulated levels. At 12 months, bucks were castrated, and testes were weighed and prepared for histological analysis. Testes diameters showed no significant difference (p<0.05): 24.52±0.43 mm (GnRHtreated group) and 25.92±0.45 mm (control group). However, yearling testicular mass differed significantly (p<0.05): 41.50±5.80g (GnRH-treated group) and 38.80±7.58g (control group). The number and make-up of seminiferous tubular cells (cells of Sertoli, germ cells in the form of spermatogonia, developing into spermatocytes, further maturing into spermatids, and ultimately forming spermatozoa) indicated increased spermatogenesis in the GnRH-treated group. It is concluded that GnRH super-stimulation increased spermatozoa production in the West African dwarf buck.

Infectious Bursal disease (IBD) is an immunosuppressive disease of young chicks, which is responsible for major economic losses in the poultry industry worldwide, particularly for the last decades. This study utilized a cross-sectional approach to evaluate Infectious bursal disease virus (IBDV) maternally derived antibody decay rate in day old chicks (D.O.C) obtained from different hatcheries in Nigeria. Of the 450 serum samples collected through random selection with replacement method, (i.e 90 samples from the 5 hatcheries designated as farms A – E), it was observed that farm A at day 1 had mean Elisa titre of (4213 ± 366.66), farm B (2178.225 ± 292.477), farm C (1629.699 ± 229.2197), farm D (3452.609 ± 403.64.6469) and farm E (1651.789 ± 201.6811), these values were far above the protective (positive) level of 875, recommended by IDvet manual with (S/P ratios of 0.350). This level was maintained, although, with minimal decays, up to day 7 for farms A, D and E but farm B and C did not exceed day 6 and day 5 respectively. Only farm D presented protective (positive) value that lasted to day 13. The best fit for this decay rate was calculated to be Y = -2263In(x) + 3714 (week) with R2 = (0.903). From these studies we could deduce that these farms were truly vaccinated or immunized as expected and they presented different antibody titres with variable decay rates. It would have been a good idea to recommend that same vaccination schedule should not be applied indiscriminately to broilers from these farms like other researchers have, but this would rather be to the detriment of many farmers who may not be privileged to access the detailed information on which schedule is meant for which farm .We therefor recommend that broilers from these hatcheries be vaccinated between day 7 to day 10 post hatch and a booster dose (if necessary) should be administered a week after, with an intermediate plus strain vaccine type that has the capacity to penetrate through the MDA and induce humoral-immunity-in- thechicks.

Kulturbesitz: Konflikte um archäologische Objekte in der deutsch-osmanischen Politik 1898-1918
Authors: Willert Sebastian 
Published: May 2024

Wie deutsche Archäologen Altertümer aus dem Osmanischen Reich nach Preußen brachten - und damit diplomatische Krisen auslösten. Im internationalen Wettstreit um die Aneignung archäologischer Funde entwickelte sich Preußen im 19. Jahrhundert zu einem wichtigen globalen Akteur. Gleichzeitig intensivierte Berlin seine Aktivitäten im Osmanischen Reich. Neben Grabungsobjekten brachten deutsche Archäologen ganze Architekturfragmente aus dem von Istanbul regierten Gebiet nach Preußen - auch mithilfe von Diplomaten und der Einflussnahme des Kaisers Wilhelm II. Die Osmanen wiederum versuchten durch Gesetzgebungen, den Zugang zu ihren antiken Stätten zu regulieren. Sebastian Willert widmet sich in seiner Studie Akteuren, Abkommen und rechtlichen Rahmenbedingungen der Aneignung archäologischer Objekte und islamischer Kunst. Er untersucht, welche politischen Auswirkungen der Transfer von Altertümern hatte, und deckt anhand konkreter Beispiele bisher unbekannte Vorgänge, Verhandlungsstränge und Akteursnetzwerke auf. Auf Basis umfassenden Materials aus deutschen und türkischen Archiven analysiert Willert, inwiefern die »Erbeutung« von Kulturgut diplomatische Krisen zwischen Istanbul und Berlin auslöste. Preußen und dem Osmanischen Reich ging es nicht zuletzt darum, mithilfe der Archäologie den eigenen imperialen Machtanspruch zu demonstrieren.

Ontology of statistical indicators of yield time series for forecasting by machine learning methods
Authors: Рыжова О.А. 
Published: May 2024

В статье раскрывается сущность онтологии как альтернативной современной базы данных, которая представляет собой формальное описание знаний из домена, учитывающее связи всех элементов, для выявления новых факторов и взаимосвязей. Ризонинг позволяет выявить в онтологии похожие данные. Чтобы составить прогноз, необходимо систематизировать полученные данные. Не всегда удобно использовать таблицы, поэтому возникла система организации знаний в виде графов – онтология. Прогноз, составленный на основе временных рядов, получается более точным. Для моделирования принято использовать параметрические и непараметрические модели, линейные и нелинейные модели, одномерные и многомерные модели. Точный прогноз урожайности составить сложно, так как многие параметры временных рядов заранее неизвестны, но их необходимо учесть при моделировании. Сложно проанализировать статистические показатели с использованием нелинейных методов прогнозирования. Необходимо как можно меньше использовать факторы, дающие большое среднеквадратическое отклонение векторов входа и выхода.
This article reveals the essence of ontology as an alternative modern database, which is a formal description of knowledge from the domain, taking into account the connections of all elements, in order to identify new factors and relationships. Risoning allows you to identify similar data in the ontology. To make a forecast, it is necessary to systematize the data obtained. It is not always convenient to use tables, so there was a system of organizing knowledge in the form of graphs – ontology. The forecast based on time series is more accurate. It is customary to use parametric and nonparametric models, linear and nonlinear models, one-dimensional and multidimensional models for modeling. It is difficult to make an accurate yield forecast, since many time series parameters are unknown in advance, but they must be taken into account when modeling. It is difficult to analyze statistical indicators using nonlinear forecasting methods. It is necessary to use as little as possible the factors that give a large standard deviation of the input and output vectors.

Implication of Institutional Frameworks Governing Land Tenure Security in Social-Economic Dynamics: Experience from Iringa District in Tanzania
Authors: Usika Gerald , Urassa Justin , Kabote Samwel 
Published: May 2024

Purpose: The study aimed to examine the implication of institutional frameworks governing land tenure security in socioeconomic dynamics in the Iringa district. The study used the case of the Iringa district to investigate the institutional framework that provides implications for the governance of land tenure security in Tanzania.
Methodology: The study employed phenomenography by collecting primary data from 16 key informants selected from village and district levels. Data from key informants were complemented by documentary review with perception considered deductively.
Findings: Findings confirmed the existence of two principal institutional frameworks; the Land Act No. 5 of 1999 and the Village Land Act No. 4 of 1999. Nonetheless, bureaucracy, inadequate policy dissemination, and poverty emerged as primary causes of deviations in land policy implementation in the study area. This study concludes that the successful implementation of Tanzania's land policy in the Iringa District Council has significantly facilitated land tenure security through the issuance of a Certificate of Customary Right of Occupancy. Establishing a robust institutional framework and clear land use rules has been central to this success. However, challenges such as complex Certificate of Customary Right of Occupancy acquisition procedures, bureaucracy, inadequate policy dissemination, and prevalent poverty in rural areas have been identified as impediments.
Unique Contribution to Theory, Practice and Policy: The study was guided by Institutional Theory which describes the interaction of human beings with existing natural resources, the institution involves the regulation of formal rules from constitutions, status laws, and other legal frameworks controlling the interaction and relationship of human behavior. The study contributed to the theory by establishing the relationship between the organization and enforcement of policy and regulatory framework that governs land tenure. Also, the study recommends expanding the Certificate of Customary Right of Occupancy issuance, strengthening local land administration, simplifying land use regulations, facilitating easier access to Certificate of Customary Right of Occupancy especially for impoverished households, and implementing strategies to reduce bureaucracy and enhancing policy understanding at the grassroots level. These measures aim to enhance land tenure security and support sustainable development in rural communities.
