Humans are in–separately linked to the existence of vegetables, as they are the source of several bio–products essential for the survival of the animal kingdom. The importance of vegetables from the point of view of the food industry is determined by their complex chemical content that is important to the human body and this includes organic substances (lipids, proteins, carbohydrates and organic acids). This study examines comparatively the levels of lipid compositions in the samples of dried carrot (Daucus carota L) and cucumber (Cucumis sativus L). The fatty acid, phospholipid and sterol compositions were determined from the samples using Gas Chromatography method. The most concentrated fatty acid (%) was linoleic acid (C18:2) (54.04 and 57.62) and the least was arachidic acid (C20:0) (0.01 and 0.01) for Daucus carota and Cucumis sativus, respectively. The result showed the quality parameters of fatty acids investigated in the Daucus carota and Cucumis sativus samples as: SFA (23.36 and 20.15 %); MUFA (15.27 and 15.5 %); PUFA (60.37 and 64.58 %); DUFA (54.04 and 57.62 %); TUFA (75.64 and 79.83 %); MUFA/SFA (0.63 and 0.76 %); PUFA/SFA (2.87 and 3.47 %); O/L (0.23 and 0.23 %). The total phospholipid contents present in the Daucus carota and Cucumis sativus were 546.11 and 594.51 mg/100 g while that of phytosterols were 366.16 and 376.69 mg/100 g, respectively. Phosphatidycholine has the highest content in both samples (265.80 and 283.64 mg/100 g). The concentrations of phytosterols were very low except in sitosterol (198.71 and 200.53 mg/100 g), stig–masterol (118.42 and 120.39) and campesterol (34.48 and 34.44 mg/100 g) for the Daucus carota and Cucumis sativus samples, respectively. This study revealed that Daucus carota and Cucumis sativus have high values of UFA that make them a special kind of vegetables for nutritional and health applications, and may be a good source of phytosterols.

Objective: We report the results we obtained on DNA concerning the colours of the face, of the eyes and of the hairs of Napoleon the First (1769-1821). Methods: His genomic DNA was previously extracted from one of her authenticated hair lock (dating from 1811). The DNA polymorphisms tested were those of the MATP gene for the skin colour, and of the rs 12913822 in intron 86 of the HERC2 for the eye colour ; for hair colour, the entire DNA sequence of the MC1-R gene was studied, in the search of alleles responsible of the red hair. Results: The genomic DNA is homozygous FF for the F374L polymorphism of the MATPgene ; consequently, Napoleon had a pale face. It is also homozygous CC for the rs12913822 polymorphism ; it results that he had a 99% probability of having clear (blue or green) eyes. The examination of the complete DNA sequence of the MC1-R gene shows the Napoleon genomic DNA is heterozygous CG for the rs1805009 polymorphism , that corresponding to the D294H mutation which is the most frequent of the three common mutations of the gene causing red hairs. Conclusions: According to results obtained on genotypic studies, Napoleon was of the phenotype : pale skin of the face, blue or grey colours of the eyes, and with red hairs. These distinctive features can be observed on a picture of Napoleon dating from 1803, and was also reported by several of the Napoleon’s contemporaries.

Bingerville is one of the cities of the District of Abidjan which are experiencing rampant urbanization. Despite this urbanization, the government has managed to preserve an area called the Dahliafleur Reserve as a refuge for biodiversity in this highly urbanized area. The sustainable management of this Reserve inevitably requires knowledge of the different types of land use and flora. The objective of the present study was to determine the ecological role that this Reserve could play. Land cover mapping and botanical inventories were the main methods used. The results obtained revealed a variability of the types of occupation and of the soil with different surface areas. The Reserve is made up of mosaics of secondary forests, fallow land and bamboo groves. The characterization of the flora made it possible to identify 107 species divided into 87 genera and 44 families. The Guinean-Congolese species are the most abundant. Phanerophytes are dominant in the Reserve. The presence of a non-negligible number of species with special status marks an interest in conservation in this anthropized environment. The diversity indices and specific richness are low. These relatively low values confirm the state of degradation of the vegetation already revealed by satellite images in the Reserve.

To be able to design vaccine or even a cure for COVID-19, it is particularly important to understand how SARS-CoV-2, as a single stranded RNA virus, is multiplied within host cells and which factors are controlling this multiplication. Here, we have analyzed the process of coronavirus RNA replication within host cell with the aim to find out the characteristics of this process. For that purpose, we have utilized the Resonant Recognition Model (RRM), which is biophysical model capable of identifying parameters (frequencies) related to specific macromolecular (protein, DNA, RNA) functions and/or interactions. The RRM model is unique with its capability to directly analyze interactions between amino acid macromolecules (proteins) and nucleotide macromolecules (DNA, RNA). Using the RRM model, we have identified parameters that characterize two steps in coronavirus RNA replication i.e., initiation of replication and replication by itself. These parameters can be used in our future research to design peptides, that will be able to interfere with either or both of those processes.

Adequate leadership is a vital key to the successful performance of any firm or business, and it is much more important to the construction industry. The main objective of this paper is to explore the relationship between different leadership style practices and project success in the Zambian construction industry. The data used in this research were derived from both primary and secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected through a structured questionnaire aimed at 150 project and construction managers in the Zambian construction industry. However, 110 questionnaires were received representing a 73% response rate. Data from the questionnaire were analyzed using SPSS 21.0 software. Correlation analysis was used to determine the relationship between leadership styles and project success. Likewise, the relationship between the different leadership styles and project successes in the Zambian construction industry was investigated using Pearson Product-moment Correlation Coefficient. Findings from the study revealed that there is a positive relationship between transactional leadership and project success. The results further revealed that there is no relationship between Laissez faire leadership style and construction project success. However, the study explores the relationship between leadership styles and project success in the Zambian construction industry. The study contributes to the body of knowledge of construction leadership by providing a robust background on construction leadership style practices of project and construction managers.

Carica papaya (Pawpaw), a tropical plant with inexpensive fruit is underutilized and highly consumed in the ripe form in Nigeria. The fruit is reportedly high in niacin, vitamin C and calcium, with therapeutic properties. The matured unripe fruit is sliced, dried and cooked into soups by Tiv people of Benue State, Nigeria. The study was carried out to determine the nutrient, antinutrient and sensory attributes of three local soups prepared from unripe Pawpaw fruit as consumed by Tiv people. Fresh matured unripe Pawpaw fruit was obtained from Department of Agronomy, University of Ibadan research farm, washed, peeled, sliced into chips and sun-dried. Sun-dried chips were rehydrated and prepared into three (Poucho, Tomato and Egusi) soups. Fresh Pawpaw fruit (PF), dry pawpaw chips (PC), Poucho (PS) and Egusi (ES) soups, and tomato stew (TS) were analysed for proximate, mineral, vitamin and anti-nutrient composition using standard methods of AOAC. Sensory attributes were evaluated using 30 panelists on nine-point hedonic scale. Dry PC and soups contained 12.0-55.2g moisture, 3.84-8.74g crude protein, 0.3-7.1g crude fat, and 82.1-24.6g carbohydrates /100g sample. Tomato stew was highest in carbohydrate, PS highest in crude fat, ES in protein and energy. The soups were rich in both macro and microminerals, with ES having highest values. The three soups were rich in beta-carotene, vitamins C and E, and low in antinutrients. The soups were acceptable to the panelists, and are hence, recommended for improving dietary diversity, antioxidant and micronutrient intake of consumers.

One of the most genuine issues found in desalination utilizing reverse osmosis (RO) is concentrate or administration of brine. This concentrate can be utilized as a raw material for production of minerals. The antiscalants present in the RO handle ought to be removed after the process of salt crystallization. The precipitation of the amount of sulfate and carbonate from calcium can be modulated by the antiscalants in the process of reverse osmosis. However, the modulation of calcium phosphate has not been highlighted in literature. This gap in the literature instigated us to explore the activity of the antiscalants in the scaling of calcium phosphate in the RO blocks by a mild method. Nowadays, most RO desalination plants are utilizing phosphorus-based antiscalants to prevent scaling and to realize tall layer execution, as measured by diminished transmembrane weight, salt entry, and expanded saturate stream. In any case, phosphorus antiscalants in brine disposal can be an natural issue that ought to be considered and considered when introducing a desalination plant. Sodium Hexametaphosphate (SHMP) is reckoned excellent antiscalant agent which utilizes to deal with scaling in RO films. The sodium hexametaphosphate solution is prepared by mixing in sodium hexametaphosphate vessel and dosed to the feed water through. However, the apparatus containing sodium hexametaphosphate was highly prone to contamination by bacteria. The amount of bacteria within the apparatus after 36 days of makeup was far too high to be analysed as it reached a value of beyond Too Numerous To Count (TNTC). The polyphosphate can be transformed into orthophosphate in presence of sodium hexametaphosphate solution. The conversion is influenced by parameters like temperature, concentration and different nutrients responsible for the growth of microbes. Thus a study was conducted for the detection of free phosphate in a solution of sodium hexametaphosphate. Since hydrogen sulfide (H2S) can be generated in raw water, the use of chlorine was averted completely. The tanks and injection lines containing sodium hexametaphosphate solution was disinfected using sodium metabisulfite (SBS). The optimum concentration of sodium metabisulphate solution required for sterilization along with reducing the formation of the free phosphate was studied. The reaction of the SBS in the apparatus containing sodium hexametaphosphate solution was studied. Furthermore the interaction between the SBS with the sodium hexametaphosphate solution in connection with the Microguard Filter (MGF) influencing the efficacy and output of the RO system was studied.

Background: Cortisol is a steroid hormone, in the glucocorticoid class of hormones that functions to increase blood sugar through gluconeogenesis. Diabetogenic hormones such as cortisol play a role in the complications of diabetes mellitus and abnormally high cortisol exerts anti-insulin effect that leads to reduction in insulin sensitivity which is a major factor contributing to development of type2 diabetes mellitus. Aim: This study aimed at evaluating the serum level of Cortisol in type-2 diabetes mellitus patients. Materials and Methods: Samples from thirty (30) confirmed drug treated type2 diabetic subjects attending clinic at federal teaching hospital Abakaliki and fifteen (15) non-diabetic volunteers were analyzed of serum cortisol level using enzyme linked immunosorbent assay (ELISA) method. The data generated was analyzed using statistical software IBM SPSS version 20.0. The results were expressed as mean+ SEM. Data from this study was analyzed using T-paired test analysis. Results and Discussion: This study showed that the serum cortisol level was normal and had no significant difference (p=0.13) in treated type2 diabetic subjects (2.94+0.73nmol/l) compared to that of the control subjects (1.83+0.06). Also, the mean levels of serum cortisol in comparison with the duration of treatment showed that type2 diabetic subjects with treatment duration of 1-2years showed higher significant difference (P=0.03) in their mean levels of cortisol (2.51+0.54) compared to subjects with treatment duration of 6-10years (0.82+0.05). Conclusion: Serum cortisol level in a well drug treated type2 diabetic subjects was observed to be normal with an inverse correlation with duration of treatment.

Diabetogenic hormones such as cortisol play a role in the complications of diabetes mellitus and abnormally high cortisol exerts anti-insulin effect that leads to reduction in insulin sensitivity which is a major factor contributing to development of type2 diabetes mellitus. Aim: This study aimed at evaluating the serum level of Cortisol in type-2 diabetes mellitus patients. Materials and Methods: Samples from thirty (30) confirmed drug treated type2 diabetic subjects attending clinic at federal teaching hospital Abakaliki and fifteen (15) non-diabetic volunteers were analyzed of serum cortisol level using enzyme linked immunosorbent assay (ELISA) method. The data generated was analyzed using statistical software IBM SPSS version 20.0. The results were expressed as mean+ SEM. Data from this study was analyzed using T-paired test analysis.

Seasonings, also known as spices and herbs, are appreciated for their culinary properties and potential health benefits. They are a rich source of beneficial bioactive phytochemicals. The objective of this study was to assess the effect of addition of different proportions of butternut squash seed (BS) powder on the quality characteristics and antioxidant potential of seasoning. The BS powder enhanced the color values and antioxidant potentials of the seasoning. The antioxidant activity, as 1,1-diphenyl-2-picrylhydrazyl (DPPH), of seasonings increased by up to 30.92% in the sample containing 5% BS powder. The total phenolics content was also increased by 91.40% with the addition of 5% BS powder. Seasonings prepared by adding BS powder could be used as good sources of natural antioxidants. This study suggests that the addition of BS powder could enhance the color value as well as antioxidant potential of seasonings.
