The paper acknowledged the quality and competitive market value of NILEST leather products. Promoted leather products were purposively selected and arranged for a photographic session. Each of the leather works were photographed from different sides. The photographed product images were enhanced on the computer and uploaded for promotion into an existing ecommerce platform. The opinions of one hundred thirty (130) e-commerce shoppers were sampled through a closed questionnaire. The outcome showed that appealing display of leather works from all sides on an e-commerce platform gives shoppers a convincing grasp of the promoted products and this can influence patronage of the leather works. It was recommended that the leather industry should explore the limitless capabilities offered by e-commerce to leverage an impressive market acceptance transcending geographical barriers. Also, makers of leather products must embrace best practices in their value-chain of production to churn out appealing leather works that attracts patronage online.","PeriodicalId":236361,"journal":{"name":"Nigerian Journal of Technological Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128533518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multistage sampling technique was used to select the respondents and the study area. Data were collected from 100 fisher folks from Ilaje and Ese-Odo Local Government Areas (LGAs), using a well-structured questionnaire and interview schedule. Data were analyzed using descriptive statistics. Kruskal Wallis test (KWt) was used to determine the level of livelihood diversification among the fisher folks. The most prominent roles of men in the study area are fishing both offshore and inshore (66%), boat owners (61%), and gear preparation (56%). On the other hand, the participation of women in fisheries is mostly sorting of fish caught (81%), salting for processing (79%), washing of fish and fishing gears (69%), and smoking (66%). Women also dominate fish distribution and marketing activities which include transporting of fish from home to the market place, display and bargaining. The result of the Kruskal Wallis test (KWt) revealed that the main occupation of the different groups is fishing, where the married class was the most predominant group. For gender, fishing remains the most engaged main occupation with more male than female at 0.01 level of significance. \u0000Key words: Sustainable Livelihood, Fisheries and Gender","PeriodicalId":236361,"journal":{"name":"Nigerian Journal of Technological Research","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129140165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each smoke-dried fish sample was placed in a plastic container with perforated lids covered with muslin cloth and Piper guineense fruit meal was sprinkled at varying quantities (0.0 g, 2.5 g, 5.0 g, 7.5 g and 10.0 g). Ten (10) adults of Dermestes maculatus bred from highly infested smoke-dried fish samples were introduced into each container and covered air-tight for seven (7) days. Mortality of D. maculatus was significantly different (p = .05) in all treatments and increased with an increase in the quantity of P. guineense and number of days. Mortality ranged between 73.33 and 100 % in treated groups while none was recorded in the control. Chemical compositions in treatments showed an increase in crude protein, lipids and lower moisture content at higher inclusion levels.

Chitin whiskers (CHWs) were used as insoluble substrates, while poly (acrylic) acid (PAA) is used as soluble additive. The crystals were grown in chitin whiskers, Poly (acrylic) acid and CHW/PAA composites. The volume fractions for aragonite, vaterite, and calcite are 0.10, 0.25, and 0.65, respectively, in the absence of chitin whiskers or Poly (acrylic) acid. Calcite and aragonite volume fractions decrease in favour of vaterite when PAA and or CHWs were added. SEM images in the absence of CHWs and PAA shows rhombohedral calcites that display steady and step like plane appearances with an average edge of between 1.3 and 1.4 μm. In the presence of only CHWs, the SEM images show a mixture of ellipsoidal and spherical shape vaterites. The spherical vaterites have smooth, rough, and some irregular surfaces. Rod-like aragonite polymorphs were seen when only PAA was used as the template. In the presence of both PAA and CHWs, the rhombohedral shape showed roughness with irregular faces. \u0000Keywords: Chitin whisker, Calcium carbonate, Calcium, vaterite aragonite, Polymorph, Mole fraction","PeriodicalId":236361,"journal":{"name":"Nigerian Journal of Technological Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123731079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
