Fibroblast is the principal active cell of connective tissue. It can be used as a useful tool for reproductive and therapeutic studies for its ability to easily grow in culture, create a preferable environment to growth and can be used as both for primary and permanent cell lines. Somatic cell nuclear transfer (SCNT) is commonly used for complete genetic reprogramming of a fully differentiated cell (e.g., fibroblast). SCNT is influential means for studying genomic imprinting, nuclear-cytoplasmic interaction, totipotency, and the contribution of paternal and maternal genomes to developing embryos. For reproductive cloning, SCNT is a fundamental step. So, the objective of this study was to adapt buffalo fibroblast cell culture protocol in order to develop fibroblast cell line for SCNT. River type buffalo ear skin tissues were used for developing primary cell culture to establish fibroblast cell line. Cells were grown in vitro. The general morphology and growth of cell population and presence of any microbial contaminants were checked regularly under an inverted microscope in phase contrast. Cells were counted by using hemocytometers. Sliced tissue was sown in 15 culture dishes to create primary and subcultures, and cells were cultivated in 6 of those dishes. Cell confluence varied from 70 to 80%. There were performed subcultures. Cell confluence in passages 1 through 10 varied from 73 to 90%. Cell concentration was 2.72 x 105, 2.68 x 105, and 2.65 x 105 per ml in passages 1, 5, and 10, respectively. Viable cells ranged from 84-93% of the total cells in passages 1 through 10. Different passages of cultivated fibroblast cells showed significantly varying viability (p< 0.05). Cultured fibroblast cell lines could now be preserved using cryotechnology.

This study investigates haematological parameters in goat treated with three medicinal plants (Vernonia amygdalina, Ocimum grattisimum and Talinum triangulare). Twenty goats were infected with L3 larval stage of nematode parasite and the experiment lasted for 22 days. Standard procedures were employed to investigate the extraction of medicinal plants, animal infection and treatment and blood parameters of the treated goat with medicinal plants. The goat treated with Vernonia amygdalina and Ocimum grattissimum showed high reduction in Packed Cell Volume (PCV), Red Blood Cell (RBC) and Haemoglobin (HB). This showed that the goat treated with these medicinal plants were anaemic. The goat treated with Talinum triangulare showed little reduction in PCV, RBC and HB. This signified that Talinum triangulare can be used to improve vitality of goat. Other parameters like White Blood Cell (WBC), Mean Cell Volume (MCV), Mean Cell Haemoglobin (MCH) and Mean Cell Heamoglobin Concentration (MCHC) had no significant difference from control. Erythrocyte Sedimentation Rate (ESR) had significant difference from control. Hence the research can be used for increasing the economy status of the goat.

A total number of one hundred and twenty (120) unsexed four weeks old broiler birds were used to determine the impact of Costus afer extract on the growth performance and cost benefit analysis of broiler birds.One week was used for brooding the chicks after which they were randomly distributed into five treatment groups of thirty birds replicated three times with ten birdsper replicate in a completely randomized design (CRD). The homogenous Costus afer extract was administered at inclusion levels of 0, 5, 10 and 15 mls per litre of drinking water corresponding to treatments 1, 2, 3 and 4 respectively. Feed and water were given ad-libitum and recorded throughout the experimental period which lasted for five weeks. The proximate analysis of Costus afer leaves and stem extract indicates lower values in CP (2.50%), NFE (0.22%) and ME (0.10 kcal/kg). Data obtained showed that the growth performance parameters were significantly (p<0.05) influenced across the treatment group. Birds in treatment 4 (15 ml) had the highest (p<0.05) values of 3620.00 g/b, 102.38 g/b and 1.34 for final body weight, daily weight gain and feed conversion ratio respectively. The cost benefit analysis table displaced a net profit and cost benefit ratio of superiority (p<0.05) for birds placed in treatment 4 (15 ml) with values obtained as #2934.00/b and 1.22/b, while the lowest values for net profit and cost benefit ratio were reported in treatment 1 with #616.40/b and 6.01/b respectively. Based on the facts reported in the present research work, it can be concluded that Costus afer leaves and stem extract can be administered to broiler birds up to 15 ml/litre of drinking water without any decline or negative impact on the performance and invariably yields a better profit. Thus, best possible result was recorded in treatment 4 (15 ml/l).

Fish demand by consumers keeps increasing, yet constraints to the production of fish are encountered, the commonest of which is the high cost and difficulty in acquiring fish feeds in Nigeria. The objective of this study was to determine the effect of the formulated test diets of 40% protein concentrate using varying levels of chicken offal diets on the haematological parameters of the African Catfish (Clarias gariepinus). The chicken offal was used to replace fish meal at inclusion levels of 0% (control, treatment A), 25% (treatment B), 50% (treatment C), 75% (treatment D) and 100% (treatment E) respectively. Three hundred (300) fingerlings of average length, 8.12±0.48 cm, and average weight, 3.68±0.00 g, were stocked in concrete tanks. Fish were fed at 5 per cent body weight for 8 months. Physicochemical parameters including; water temperature (°C), pH, dissolved oxygen and ammonia were monitored every four days and maintained within acceptable ranges for fish culture. Data obtained were analysed using analysis of variance (ANOVA). Results showed haemoglobin (Hb), Packed cell volume (PCV), Mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) to be statistically different (ANOVA, p<0.05) between the treatments, although no significant difference (ANOVA, p>0.05) was observed in white blood cell (WBC), Mean Corpuscular haemoglobin (MCH) and erythrocyte sedimentation rate (ESR). Haematological parameters results were within the ranges for fish well-being. Chicken offal were suitable as partial replacement at (25, 50, 75 and 100%) for fish meal, it enhanced the hematological performance of C. gariepinus due to its mineral components.

This study aimed to identify breeding practices and selection criteria used by livestock breeders in the Drâa-Tafilalet region in southeastern Morocco. Five sites in the region with three to five rural districts each were selected, within each district, one to eight breeders of each livestock species were interviewed. There were 305 surveys conducted in 21 districts with 60, 105, 71, 21, 35 and 13 breeders of cattle, sheep, goats, camels, chickens and rabbits, respectively. Frequencies were calculated to describe breeding practices and index values were used to examine selection criteria employed by breeders. A total of 74.6% of cattle breeders used natural mating, 16.9% used artificial insemination, and 8.47% used both. However, for other livestock species, natural mating was the only method of mating. In cattle, sheep, goats, camels, chickens and rabbits, the proportion of breeding males from the breeder's own herd was 12.8%, 73.1%, 86.1%, 56.1%, 81.6% and 92.3%, respectively. Breeders who practiced the selection of breeding animals were 74.6%, while the rest used random selection. In the former group, 73.9% selected both males and females, 4.26% selected only males and 21.8% selected only females. In selecting breeding animals, body size ranked first for cattle, sheep, goat, camel, chicken, and rabbit breeders with indices of 0.37, 0.41, 0.43, 0.43, 0.47 and 0.50, respectively for males, and 0.33, 0.34, 0.41, 0.41, 0.44 and 0.50, respectively for females. It was concluded that breeders' existing breeding practices and selection criteria should be considered in order to minimize the failure of genetic improvement programs in livestock production.

Published: January 2024

After-sales service is a key part of maintaining and increasing customers for companies, both for products and services, but the problem is that it is very complicated to maintain, let alone increase customers. The problems that arise are classic problems in the form of company illnesses in the form of service quality, product non-conformities, stock and delivery, employee training, IT systems and technology, and internal coordination for changes in technology and products. The aim of this research is to find out from the informants what the most dominant key words are that are often mentioned by the informants and how to compare gender and type of company in producing the most dominant variables for after-sales service. This is qualitative research with a phenomenological approach. Phenomenologists describe the main points of each informant's life experiences. Phenomenologists describe in detail from informants where the informants feel a phenomenon. The sample determined that five informants had expertise in their fields, as proven by their top positions in their companies. The analysis of this research was assisted by qualitative tools from Nvivo 12, and there is no doubt about international evidence, especially in data testing or analysis tests. The research instrument was adopted from previous research and assisted by theoretical studies to simplify and help determine policies for the company's after-sales service. The results obtained were that five informants had strong and moderate relationship values for each informant included. The comparison diagram or chart test is unique in that each informant, whether gender, female, or male, shows that the customer service variable has the strongest relationship with after-sales service.

Energy, Ecology, and the Remaking of West German Politics in the 1970s and 1980s
Authors: Gross Stephen G.
Published: January 2024

This article traces the transformation of West Germany's political system during the 1970s and 1980s, when an extra-parliamentary ecological opposition emerged to challenge the governing Social Democratic Party (SPD). Demographic, economic, and structural features in West Germany's political system created the space for this opposition, eventually leading to the formation of the Green Party. This article argues that ideas about energy were crucial to the movement's success, providing a focal point for reform that aimed to spur an energy transition. This movement of experts and activists pulled West Germany's political system in an ecological direction, forcing the SPD to become green itself. The transformation of West Germany's political system, in turn, set the Federal Republic on a different energy trajectory than the United States, Great Britain, and France.

Effect of adding technologically processed antibodies to interferon-gamma into a parent solution on the structural features of triglycine sulfate crystals grown from this solution
Authors: Stepanov G. O. , Rodionova N. N. , Konstantinov R. R. , Subbotin K. A.
Published: January 2024

Objectives. Ferroelectric triglycine sulfate (TGS) belongs to a group of crystals whose properties are sensitive even to minor changes in growth conditions. The mechanism of spontaneous polarization in TGS is associated with the adjustment of protons which participate in the formation of hydrogen bonds. Therefore, the state of the parent solution plays an important role in the crystal formation. The study aims to investigate the structural features of TGS crystals grown using aqueous alcoholic solutions of technologically processed antibodies to interferon-gamma, in comparison with those of the crystals grown using the control solutions (technologically processed phosphate-buffered saline and intact aqueous alcoholic solution).

Methods. X-ray diffraction assay and Raman spectroscopy.

Results. The effect of solutions of the technologically processed antibodies to interferongamma added to a parent solution on the growth of TGS single crystals is established. This effect manifests in the changing in occupancy of the proton sublattice of the crystal grown from the parent solution containing technologically processed antibodies to interferon-gamma, as compared with the crystals grown from the control solutions. In the case of the crystal grown from the solution containing technologically processed antibodies to interferon-gamma, this change in the occupancy of the proton lattice is expressed in an increase in the length of N2–C3 bonds.

Conclusions. Adding the technologically processed antibodies in the parent solution before the crystal growth can affect the structure of TGS crystals.

Methods. The process of the production of sprayed and contact polyureas involves a number of difficulties, not least in terms of the cost of the components and high-pressure equipment. For this reason, mathematical modeling was used to optimize experimental design. The curing time of the composition was measured under conditions simulated to be close to actual. After thermostating and mixing Components A and B in predetermined ratios, the gelation time was measured to represent the curing time of the composition. The hardness of the material was determined by the Shore method according to GOST 24621-91. Tensile strength and relative elongation were determined according to a standard method (GOST 30436-96).

Results. The effect of three AADs on the properties of the finished polyurea was studied. It was found that the introduction of two of them (AAD-1 and AAD-2) into polyurea in an amount of up to 40 wt % produces slow-curing (>250 s) polyureas capable of manual application. The finished products have physical properties on par with machine-poured materials (breaking strength >73 MPa; tensile strength >23 MPa; elongation >500%). Compiled regression equations were used to construct graphs of equal levels showing the possible areas of directed modification of the studied compositions.

Conclusions. AAD can be used as a modifying component for polyurea systems to obtain slow- curing polyureas with high performance properties, which can be purposefully controlled by mathematical modeling. The resulting products have commercial value due to their combination of valuable physical and mechanical properties.

Statistical survey data of each province in Java indicates that the number of educated unemployed individuals holding a high school or university diploma is higher than that of lower-educated unemployed individuals. The increase in the number of educated unemployed individuals suggests that the government has not been successful in increasing job opportunities and establishing an effective education system to compete in the workforce. A significant increase happened in 2020 due to Covid-19 pandemic, leading to numerous dismissals. This research aims to discover the factors influencing educated unemployment in Java using Fixed Effect Model (FEM) panel data analysis, which comprises cross-sectional data from six provinces in Java and time series data spanning from 2016 to 2022. The results of the research show that education level variable (average years of schooling) has a negative and insignificant influence on educated unemployment, provincial minimum wage has a negative and significant influence on educated unemployment, GRDP has a positive and insignificant influence on educated unemployment, foreign direct investment has a positive and significant effect on educated unemployment, local direct investment has a positive and significant influence on educated unemployment, and Covid-19 pandemic has a positive and significant influence on educated unemployment in Java from 2016 to 2022.

The Indonesian government announced the relocation of the national capital from Jakarta to East Kalimantan province in 2019. The term ‘Capital of the Archipelago’ or Ibu Kota Nusantara (IKN) was approved as the name of the new capital of the Republic of Indonesia. This study conducted visualization and bibliometric analysis using VOSviewer 1.6.20 from 100 scientific articles with the keyword “Ibu Kota Nusantara” collected from Google Scholar. The frequency of article titles relevant to IKN in 2022 was greater than in 2023. In the comparison of titles with the term IKN in 2022, there were 22 articles; in 2023, there were 15 articles, so the difference was 22/15 or 1.467. Following the 12 images of IKN, there were five images related to some scientific articles that have been published, including those related to innovation and technology where IKN was imaged as a smart city, sustainable capital, environmentally friendly, green city, and greening. However, seven images need attention for the following research topics: renewable, legal, cultural, user-friendly road, unique, city of change, and solutions for equality. This study helps provide insight as a basis for further research on various innovative themes related to IKN.
