Published: September 2023

The study investigated gender in wholesale smoked-fish marketing in Kanji Lake Basin, Nigeria. Specifically, the study identified roles of individual actors in fish marketing, determined the profitability of fish marketing, analyzed the marketing efficiencies and estimated gaps in the fish marketing chain. A two-stage sampling procedure was used to select 60 wholesale smoked-fish marketers from 13 communities. Primary data were collected from wholesale smoke-fish marketers using an interview schedule. Data were analyzed using percentages, net profit margin and efficiency models. The result showed that the youths perform about 60% of task in activities such as sorting and grading, fish arrangement in cartons, loading and offloading and transportation to market centers. Wholesale fish marketing was profitable with a 4.45% return on investment (ROI) for the men, 3.76% ROI for the women and 2.88% ROI for the youths while Shepherd’s marketing efficiency was 24.84 for the men, 25.65 and 26.65 for the women and youths respectively. Also, there were no glaring gender gaps in value of fixed assets, revenue, gender-based employees and wage for the men, women and youths involved in the business. Therefore, it is recommended that capacity building which targets women and youths should be adopted and implemented by government and other relevant agencies in order to enable them compete equally with men in wholesale smoked-fish marketing.

Cashew nut (Anacardium occidentale L) is one of the most essential and major cash crops produced in Nigeria. This research, therefore, explored the economics of cashew nuts marketing in Udi Local Government Area of Enugu State, Nigeria. Primary data were sourced from cashew nut marketers through the use of well-designed questionnaires. Sixty respondents were randomly selected from three main markets in the study area. Descriptive statistics and (OLS) multiple regression models were used to achieve the study objectives. Descriptive statistics and (OLS) multiple regression models were used to achieve the objectives. Wherefore the study identified the marketing channels, analysed the cost and returns of the enterprise, determined the socio-economic factors affecting the quantity of cashew nuts marketed, and ascertained the constraints associated with cashew nuts marketing in the study area. From the results, the market was dominated by males (65%), most of the respondents (51.7%) were between 21 and 40 years, and majority were married (81.7%). An average number of the marketers (50%) had secondary school education, while 31.7% and 18.7% had primary and higher education, respectively. Most of the marketers (63.3%) bought directly from farmers, while 26.7% purchased from wholesalers. Total revenue, gross profit, and net profit were respectively ₦651,627.00, ₦120,618.00, and ₦81,067.70, showing that the business is profitable. Respondents’ socioeconomic characteristics which significantly affected quantity of cashew nut marketed were age (p < 0.1), household size (p < 0.05), and membership to market association (p < 0.05). Major constraints were seasonality of produce, high cost of transportation, bad weather (rain), and inadequate capital. It was recommended that government should provide good road networks to ease transportation problem. The marketers should form cooperative societies to facilitate easy access to credits and other relevant resources.

Published: September 2023

Soybean (Glycine max L. Merril) is one of the most nutritionally valuable legumes in Africa. However, spent automobile engine oil is always disposed indiscriminately on lands and water bodies in Nigeria, which pollutes both terrestrial and aquatic ecosystems, with adverse effects on crop growth and productivity. This study investigated the effects of spent engine oil (SEO) polluted soils on growth parameters and mitotic chromosomes of soybean. Two soybean varieties (TGX-1448-2E and local) were planted in pots filled with sandy-loam soil treated with 0, 0.1, 0.4 and 0.7% v/w SEO concentrations, in 2 × 4 factorial experiment laid in a completely randomized design with six replications. Data were collected at weekly intervals for four weeks on growth parameters (plant height, number of leaves, leaf width and leaf length) and chromosomal aberration. Data were subjected to ANOVA and means separated with LSD. Among the treatments, seed germination rate was significantly higher in TGX-1448-2E (95.0 ± 0.0-96.0 ± 0.7%) than local variety (70.0 ± 0.7-71.0 ± 0.7%). Both 0.4 and 0.7% SEO caused significant (p ≤ 0.01) reductions in plant height, number of leaves, leaf length and leaf width whereas, 0.1% did not reduce growth parameters. Treatments 0.4 and 0.7% SEO caused high chromosomal aberrations in soybean as they reduced chromosome numbers (from 40.0 to 23%), cell division, mitotic index (70.0 to 20.8%) and produced 31.7% abnormal cells. Abnormalities such as bridges, laggards and chromosome stickiness occurred. This study shows that 0.4-0.7% SEO polluted soils is phytotoxic to soybeans.

International Maritime Transport: Building a New Regulatory System?
Authors: Branellec Gurvan , Choquet Anne 
Published: September 2023

As the international transport of goods by sea involves various kinds of international trade operators, uniformity of the law appears to be the best way to satisfy the security requirements of these various operators. Nevertheless, individual States cannot create new rules for this activity, by simply unifying regulations in a conventional manner. There is a conflict between the desire for uniformity and the realities of implementing rules, as a consequence of divergences within the convention. This is the reason for which maritime actors have tried to standardize contracts, and support ruling jurisdictions. How can such practices contribute to the uniformity of soft law?
Dans la mesure où le transport maritime de marchandises implique divers types d'opérateurs commerciaux internationaux, l'uniformité de la règlementation applicable semble être le meilleur moyen de satisfaire aux exigences de sécurité de ces différents acteurs. Il est donc nécessaire de se demander si cet idéal d’uniformisation du droit du transport maritime de marchandises tenté par les États est atteignable voire même souhaitable ou s’il ne faut pas constater en la matière que les opérateurs du transport international maritime de marchandises, loin d’être pénalisés par le conflit de normes applicables, n’y trouvent pas la souplesse nécessaire pour adapter le cadre juridique à leur propre contrat de transport ?
Do the platforms where professional health organizations inform the public answer all the needed questions?
Authors: COŞKUN Burhan , KOCA Nizameddin 
Published: September 2023

Background We aimed to assess the comprehensiveness of patient information websites from academic organizations regarding the most searched statements on "nocturia.” Additionally, we aimed to analyze the frequency of these statements based on their classification as definition, etiology, diagnosis, or treatment.
Material and Methods The website www.answerthepublic.com was used to retrieve outputs related to nocturia. After applying exclusion criteria, the outputs were searched within the American Urological Association (AUA) and European Association of Urology (EAU) patient information websites, and the comprehensiveness scores were evaluated.
Results The search engine retrieved 615 results, of which 67 queries were eligible for analysis. The most searched query was "nocturia definition", with 6,600 average monthly clicks. The distribution of analyzed queries was 16.4% for definition, 46.3% for etiology, 11.9% for diagnosis, and 25.4% for treatment. The AUA and EAU websites had median comprehensiveness scores of 2.0 (IQR: 3.5) and 3.0 (IQR: 4.0), respectively, with no significant relation found (p = 0.438). The selected websites did not cover a substantial proportion of searched items related to nocturia.
Conclusions Although the patient information websites provided by prominent academic organizations offer valuable information, there needs to be more clarity between the information they provide and the public's concerns regarding nocturia. Tools like www.answerthepublic.com may provide valuable insights into public concerns but have limitations.

Authors: Gagarin V. , Nguyen Dinh 
Published: September 2023

Two new nematode species of the family Desmodoridae Filipjev, 1922, found in coral reefs in Vietnam, are described and illustrated. Metachromadora (Bradylaimus) tenuis sp. n. in body size and absence of precloacal supplements in males is close to M. (B.) asupplementa [Crites, 1961] and M. (B.) suecica (Allgen, 1929).
It differs from both species by the comparatively thinner body, comparatively shorter tail, presence of bipartite basal bulb of pharynx and shorter spicules and gubernaculum [Crites, 1961]. The table of chief of morphological characters of males 12 valid species of the genus Metachromadora (Bradylaimus) is given. Spirinia laevioides Gerlach, 1963 was described from one female and two males from atoll in the Maldives. The description was short and incomplete. Since we had a lot of material available, it was decided to rewrite and reillustrate this species.

Published: September 2023

Background: Leprosy has over time been seen as a symbol of shame and stigmatization as people affected by leprosy continue to be stigmatized and discriminated against even after they have been cured. The study aimed to assess the perceived levels of stigmatization, psychosocial well-being, and self-esteem among individuals living at a leprosy center in South-West, Nigeria.
Methods: A descriptive cross-sectional design of face-to-face research was conducted in a leprosy center using a simple random technique. The study instrument was a self-structured questionnaire containing sociodemographic details, questions on stigmatization towards the individual affected by leprosy and their family members, and questions regarding their psychosocial well-being adapted from literature, as well as questions adapted from the validated Rosenberg Self Esteem Scale (RSES) by Morris Rosenberg to assess their self-esteem. Data were analyzed with the aid of SPSS version 26 software.
Results: A total of 134 participants were included in the study. Most of the participants were females (61.2%) within the age range of 21- 40 years old (32.8%), and are students (25.4%). Out of the 134 participants, 29.1% (39) of them were affected by leprosy. The participants perceived a high level of stigmatization (37.3%), a high level of psychosocial well-being (38.8%), and demonstrated a moderate level of self-esteem (50.7%). The male gender perceived both low (B = -3.054, p = 0.004) and high (B = -1.84, p = 0.049) stigmatization at p< 0.05. The married (B = -5.421, p = 0.004), the Christians (B = 5.424, p = 0.043) and Islamic (B = 7.743, p = 0.011) participants perceived low stigmatization at p< 0.05. The participants within the age range 21 - 40 (B = 6.25, p = 0.019) and 61 – 80 years (B = 7.29, p = 0.017) perceived high psychosocial well-being while the single (B = -4.43, p = 0.049) and married (B = -5.26, p = 0.017) participants perceived low psychosocial well-being at p< 0.05. None of the demographic factors had relationships with self-esteem at p< 0.05. The perceived levels of stigmatization (r= 0.314, p= 0.0001) and psychosocial well-being (r= 0.225, p= 0.009) are associated with the level of self-esteem at p< 0.05.
Conclusion: This study concludes that the individuals affected by leprosy and their family members living at the leprosy center experienced a high level of stigmatization and, a high level of psychosocial well-being but had moderate self-esteem.
Rhizogenesis of rocket (Eruca sativa Mill.) and wall-rocket Diplotaxis tenuifolia (L.) DC.
Authors: Voitovska V. I. , Nebykova T. A. , Boiko A. I. 
Published: September 2023

Purpose. To test the efficiency of the plant growth regulating substances at different concentrations for stimulating the rhizogenesis of rocket (E. sativa) and wall-rocket (D. tenuifolia).
Methods. The experiment was carried out at the Biotechnology Laboratory of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Agrarian Sciences in 2020–2022. Rocket varieties ‘Znahar’, ‘Lybid’, ‘Zlat’, ‘Silvetta’ and wall-rocket variety ‘Liudmyla’ were used in the study. Seeds were examined for their quality indicators, sterilized with a solution of 35% laundry detergent and ethanol and seeded in vitro. Sterile seedlings were transferred to the Murashige-Skoog (MS) medium supplemented with benzylaminopurine (BAP) for propagation. Naphthylacetic acid (NAA), indolyl-3-acetic acid (IAA), indolyl-3-butyric acid (IBA) and gibberellic acid (GA) were added to the nutrient medium according to the MS prescription in different concentrations.
Results. The introduction of IBA (0.8 mg/l) and GA into the nutrient medium, regardless of the concentration, resulted in the longest root system in all treatments. The studied modification made it possible to obtain root length on the 9th day of cultivation from 7 to 64 cm and on the 14th day from 10 to 70 cm. On the 14th day of cultivation, in the plants grown under the concentration of GA >1.0 mg/l, the root not only the elongated and browned, but reached 70 cm in length. For the introduction of IBA into the medium previously supplemented with GA, on the 9th day of cultivation, negative effect was noted in all treatments, namely the elongation of internodes and central root. On the 14th day, vitrification of shoots and significant elongation of both central and lateral roots occurred in all treatments. The central root reached 70 cm in length, which is not advisable during the adaptation period. The results of the experiment indicate that on the 21st day, the longest root system (12 cm and 42 cm) was obtained in the rocket variety ‘Zlat’ (0.1 mg/l GA and 1.5 mg/l GA, respectively) and the shortest root length (6 cm and 21 cm) in the wall-rocket variety ‘Liudmyla’ (0.1 mg/l GA and 1.5 mg/l GA, respectively). Importantly, the root length of ‘Zlat’ variety on the 21st day of cultivation, compared to the 14th day, at a concentration of 0.1 mg/l increased by only 3 cm, while in the 'Liudmyla' variety by 2 cm. Considering this, it is impractical to carry out cultivation up to 21 days. The lowest root length was obtained with the use of IBA and GA: rhizogenesis occurred more slowly than in previous treatments, and on the 14th day the root length was in the range from 3 to 20 cm.
Conclusions. The longest root system in all studied treatments was obtained in variety ‘Zlat’, while shortest in ‘Liudmyla’. The optimal concentrations of NAA + IBA + GA for the cultivation of the studied rocket and wall-rocket varieties are 0.3 and 0.5 mg/l.

Published: September 2023

The purpose of the research was to study the components of crossing and evaluate the efficiency of the obtained experimental sugar beet hybrids. Selection of the best lines for the use as parent components of monogerm hybrids was performed based on their sugar yield.
Methods. Foreign pollinators of yield direction (rkБЗ4, rkБЗ5, rkБЗ6, rkБЗ7) and Ukrainian CMS lines were used in crosses. Experimental genotypes were obtained as a result of hybridization, recombination and selection. The genotypes were studied in controlled polycrosses and topcrosses. Variety testing was carried out in accordance with the standard protocols.
Results. On the basis of use various methods of selection, promising genotypes with high adaptive potential were selected. The highest productivity of hybrids (in % to the standard) with CМS1 was 111.3%, CМS2 112.3%, CМS3 108.3%, and with pollinator rkБЗ6орс 103.8%. In combinations with pollinator абБЗ1 824 / CМS3, the resulted hybrid had productivity 111.2%. The hybrids resulted from combination rkБЗ4 644 / МS2 showed productivity of 109.3%, and rk БЗ4 644 / МС3 112.1%. Hybrids with CМS1 and CMS3 testers showed the productivity of 105.9% and CМS2 105.4%. In terms of sugar yield, the best combinations were rkБЗ7мтд / МS1 with 110.8% and rkБЗ7мтд / МS3 with 108.5%. Thus, the efficiency of pollinators made up 101.5%, 101.2%, 102.5% and 102.8%, respectively.
Conclusions. Selected sugar beet hybrid components have been evaluated by their efficiency, combinational value and tolerance to the environmental conditions. A very high correlation relationship was found between foreign pollinators and Ukrainian CМS lines. It confirms their suitability as parent components of sugar beet hybrids. The efficiency of experimental hybrids depends both on components of crossing and climatic conditions of a zone of cultivation. Promising parent components of sugar beet hybrids have been selected.

Desta forma, faz-se necessário um controle mais rígido por parte dos agentes de fiscalização de modo a se garantir a qualidade e segurança do produto.
Customer Segmentation Using Machine Learning Model: An Application of RFM Analysis
Authors: Lewaaelhamd Israa 
Published: September 2023

Machine learning (ML) encompasses a diverse array of both supervised and unsupervised techniques that facilitate prediction, classification, and anomaly detection. Among the many fields of application for such techniques, customer churn prediction is a prominent one. In order to forecast customer switching, data scientists employ a variety of demographic, social, transactional, and behavioral variables and attributes. Unfortunately, many businesses in the United Kingdom still lack the comprehensive and adaptable consumer data required to perform accurate analyses. As a result, they often rely heavily on data produced by enterprise resource planning systems, which is primarily transactional in nature. Consequently, businesses are often limited to modeling and forecasting on transactional data alone and are unlikely to invest significantly in marketing research or other customer-related sources. Businesses are often limited to performing modeling and forecasting on transactional data that are most often not based on advanced techniques like recency, frequency and monetary (RFM) and ML. So, the major objective of the current work is to provide a mix of ML and RFM analysis techniques for churn prediction using mostly transactional data. The dataset was taken from the dataset search website containing online retail datasets. Every customer's RFM scores are computed based on the available data. A churn metric that indicates whether or not the customer has made a transaction in a limited time. Through this paper, different techniques are compared. We used K-means and DBSCAN clustering. By the end of this paper, it may be inferred that the act of dividing customers into six distinct clusters is a more practical and straightforward approach.
