Study of the Inheritance of Several Morphological and Chemical Traits of Several Genotypes of Tobacco (Nicotiana tabacum L.)
Full text linkThe experiment was carried out during the year 2024 to determine the genetic behavior of many different traits of the three parents of the oriental tobacco in kassab village, Lattakia, Syria, by cultivating three oriental tobacco genotypes (Basma, Prilep, and Gob-Hasan). A half-diallel cross was made between different genotypes of tobacco using random complete block design (R.C.B.D) with three replicates, to estimate the nature of gene action for many important characteristics of tobacco plants and identifying the best parents to include in breeding programs to obtain tobacco with high productivity and high quality.
Traits such as leaf length (cm), leaf width (cm), specific leaf weigh (g/cm2), nicotine (%) and sugar content in leaves (%) were measured.
The results show high differ significantly for all traits, which refer to differ among the parents. Thus increasing the effectiveness of the hybridisation programme.
The genetic analysis show the additive gene action dominated the inheritance of: leaf width (cm). But the non-additive gene action dominated the inheritance of leaf length (cm), specific leaf weigh (g/cm2), nicotine (%) and sugar content in leaves.
The Basma parent P1 exhibited a lowest means for: nicotine content in leaves (0.22)%, The Prilep parent P2 exhibited a high means for: leaf length (23.3) cm and specific leaf weigh (0.22) g/cm2. However, The Gob-Hasan parent P3 exhibited a high means for: leaf width (11.7) cm. The hybrid Prilep × Gob-Hasan exhibited the highest means for sugar content in leaves (10.67)%
Examining the Impact of Various Postures on Natural Variations in Signatures: A Systematic Investigation
Full text linkThe present study aims to examine the impact of various postures on natural variations in signatures and for the same, 640 signature samples were collected from 80 individuals (32 male and 48 female) of Jaipur city of Rajasthan, India. All the 80 participants (from age 20 – 77 years) of the study were asked to sign in 8 different postures such as keeping the paper on hand, on wall, standing, in bending posture, etc. in a pre-designed sheet having 8 columns as per posture. Both individual as well as class characteristics were analysed in all the signature samples including rhythm, pen pressure, slant, placings of dot on letters, size, spacing and dimensions, etc.
The study showed that the natural writing is characterized by variation in form, size, proportion, slant, and character combinations within specified boundaries. No two writing samples are identical in every way, and these variations were observed after analysis of all the samples. The study concludes that the basic nature of signature remains unchanged, but the dimension and presence of tremors are the two major factors that are dependent on posture and support. Thus, it may be said that there are no as such variations in parameters such as rhythm, style of writing, placing of dot, connective strokes and formation of loop, however signatures show significant variation in pen pressure and diameter with respect to variable postures
The Effects of Stocking Densities on Growth and Survival of Clarias gariepinus Burchell (1822) Fingerlings
Full text link189 Fingerlings were stocked at rate of 5, 10, 15, and 20 using a 30 liters capacity plastic tank in three replicates (E1 – E4 respectively) for period of six weeks which was carried out at Post Graduate Laboratory, Department of Zoology and Environmental Biology, Faculty of Science, Ekiti State University, Ado-Ekiti, Nigeria. The control experiment was stocked at 13 fingerlings per bowl, also in 3 replicates (E5). Feeding was done twice daily at 5% body weight. Water quality parameters monitored were pH, dissolved oxygen and temperature which fell within optimum limit for the growth of Clarias gariepinus. The initial mean weight and length of the fingerlings ranged from 0.82 - 0.9g and 4.81- 5.01cm respectively while the final mean weight and length of the fingerlings ranged from 14.61-17.93g and 11.96-13.16cm. Fingerlings stocked at 15 fingerlings per tank exhibited the lowest growth. Tank with 10 fingerlings per tank had the best specific growth rate. The stocking rate depends on the size of the container and it varies from 2 to 10 fingerlings per square meters (FAO, 2018). The survival rate for each group was recorded (Table 1). The growth and survival of African catfish (Clarias gariepinus) fingerlings reared at five stocking densities were evaluated. Fish of mean weight 0.1g were stocked in plastic tanks with three replicates for each treatment of 450 fish/m3. The fish were fed with 42% crude protein floating pellet at 5% body weight twice daily. The best growth performance and highest survival rate was obtained in E3 with mean weight gain of 17.06.±9.1g while E2 and E5 had 15.16±6.29g and 14.03±8.99g respectively. The specific growth rate was increasing daily; E1 to E5 has 6.86%, 6.94%, 5.06%, 6.67% and 6.77%, respectively. The survival rate was highest in E5 (80.77±6.44%) while E2 (80.00±6.32%), E4 (75.00±5.48%), E3 (71.11±8.07%) and E1 (63.33±8.16%) survival rate respectively. The mean weight gain, specific growth rate and survival rate were all dependent on stocking density. Therefore it can be recommended that for optimal growth of fingerlings and fast production of Clarias gariepinus should be stocked at maximum of 450 fish per cubic metre
Potential of Industrial Symbiosis in Emerging Clusters: A Case Study of Hassia, Syria
Full text linkSustainable development goals (SDGs) aim to create a sustainable future, and industrial symbiosis is a critical pathway towards sustainably. Industrial symbiosis involves the exchange and utilization of waste materials, energy, and water across industries, enhancing resource efficiency and promoting a circular economy. Industrial symbiosis may provide a lot of benefits for industrial clusters including increasing profitability and competiveness through reducing the cost of raw materials. This would help eliminate environmental problems and, hence, promote sustainability. However, the investigation of industrial interdependence in Syria faces significant challenges, including a lack of prior studies, bureaucratic obstacles, and limited documentation of input and output flows. This study proposes solutions to enhance industrial symbiosis in the industrial city of Hassia, Syria, utilizing insights from previous studies in other countries. The findings reveal a dearth of evidence for industrial symbiosis practices, with limited efforts focusing on the sale of by-products. Currently, Hassia Industrial Cluster shows limited industrial symbiosis (IS). It mainly involves partial water recycling to optimize resources and selling by-products to reduce waste and support a circular economy. Some by-products are also used in other production processes. However, the cluster lacks procedures for energy recovery, needing further exploration. Through the implementation of the proposed solutions, substantial recovery of cooling and heating capacity, as well as the utilization of by-products in the cement, concrete, and ceramics industries were achieved. The importance of industrial diversification within the industrial city was also highlighted, as it may contribute towards a crucial role in optimizing the potential for industrial symbiosis in Hassia and other industrial cities in the region

Full text linkMisalignment of work values has led to detrimental outcomes such as low commitment to duty and decreased competence levels among employees. This study investigated the effect of work values on employee performance of Deposit Money Banks in Anambra state, Nigeria. Specifically, the study examined the effect of job autonomy on employee commitment; and the effect of job security on employee competence. The study anchored on the Expectancy Theory, developed by Victor H. Vroom in 1964. Descriptive survey research design was used. The population of the study comprised 231 drawn from the three predominating deposit money banks in the state. These deposit money banks were; Fidelity Bank, First Bank of Nigeria and Zenith Bank respectively. Sample size of 146 was determined using Taro Yamane’s formula. The main research instrument that was used for the study is structured questionnaire. The research instrument was subjected to both content and construct validation. Test-re-test reliability method was adopted. Data collected for the study were quantitatively analysed using both descriptive and inferential statistics. The descriptive statistics used include mean, tables, frequencies, percentages and charts while the inferential statistics used is Ordinary Least Square (OLS) regression analysis, with aid of SPSS version 20. The hypotheses were tested at a 5% level of significance. The finding revealed that there is a statistically significant positive relationship between job autonomy and employee commitment. Also, that Job security has a statistically significant positive effect on employee competence in deposit money banks in Anambra State. The study concluded that work values has significant positive effect on employee performance in deposit money banks Nigeria. The study recommended amongst other that banks need to build in as much autonomy as possible in their job design such that will allow the employees to be able to craft their jobs in some aspect the way it will suit them, as this will go a long way in making them more committed to their jobs
Understanding Memory and Attention in Dissociative Identity Disorder (DID)
Full text linkIncreasing research has been conducted to examine the nature, diagnostic validity, symptomatology and phenomenology of Dissociative Identity Disorder (DID) in the past three decades, though little research were devoted on the understanding of its cognitive functioning. This pilot study aims at exploring a range of cognitive abilities in DID by using existing cognitive tests. Several surveys and tests were conducted in this study and it was discovered that many of the respondents could finish the ‘divided attention tasks’ and they were able to distinguish between the given older and newer version of the pictures in the cognitive memory tasks, and many could not. Overall, this study is based on the changed pictures, cognitive memory tasks and other data and information which might help explain lack of memory for the pictures or similar data or related identification tasks. Results of the study show less significant in high and low dissociators’ familiarity with such information in the participants having DID

Starch material was boiled to know their gelatinization and paste properties where we noticed difference. This review summarizes the difference in granular structure of four different rice starch’s, gel formation and paste properties
Isolation and Physico-chemical Characterization of Quercetin from the Ethanolic Extract of Syrian Hypericum perforatum L. Plant as Antibacterial
Full text linkQuercetin compound was isolated from the ethanolic extract of the flowers of the Syrian Hypericum perforatum L. plant, which was collected from the Al-Qadmus region in Syria (at an altitude of 900 meters), using column chromatography and thin layer technology. The identity of the isolated compound was confirmed using (IR, 1HNMR, 13CNMR) spectroscopy.
The effectiveness of the organic extract and the compound isolated from it was also tested against a Gram-positive bacterial strain (Staphylococcus aureus) and a Gram-negative bacterial strain (Escherichia coli) at concentrations of the extract:(5,10, 20)%, and the following quantities of the isolated compound (5,10,20µl).
The results showed that the best mobile phase for isolating quercetin from the column was (hexane ethyl acetate - ethanol) (1:2:1), then in thin layers with a displacement mixture (hexane - dichloromethane) (1:2), and it was valuable RF= 0.45.
And results also showed better effectiveness of quercetin in quantity(20µl) than the effectiveness of the ethanolic extract isolated from it at all concentrations used against the two bacterial strains mentioned previously with two levels of inhibition 21.36mm, 8.77mm for each Staph. aureus, E. coli, respectivel
The Reversed Reality: The Reported Double-Digit Incremental Economic Growth Versus the Decreasing Trend in GDP Performance in Ethiopia During 2011-2020
Full text linkEconomic development and poverty alleviation have been a priority of the Ethiopian government over the past decade. The country is one of the poorest countries in sub–Saharan Africa and there have been contradicting reports by the government during the same decade for its fast-growing economy in the region with double-digit and incremental growth. This article attempted to analyse the trend in economic performance and the financial flow into the economic sectors in the country. On the one hand, government reports have indicated that the country is economically one of the fastest growing in Africa, a position that has been seconded by international financial institutions and other bilateral donors. On the other hand, the country remains on the list of poorest countries in the world. A qualitative approach was applied in analysing the reported data on economic performance in the country from 2011-2020. The study relied on secondary data sources using aid flow records, reports of government and United Nations agencies, policy manuals, research findings, books, and journals. The GDP measure in Ethiopia during the past decade decreased from 11.39 in 2011 to 6.06 in 2020. The trend in specific economic sectors was decreasing with little progress in specific poverty indexes in the economic sector. There were marked inequalities between urban and rural areas in the country. The performance in water supply, electricity power provision and road networking in the country showed sluggish progress. The intended transition from an agriculture-led economy to an industry and services sector-led economy remained unmet. The country continued relying on foreign aid for its poverty alleviation efforts and the aid flow during the past decade showed a fluctuating trend. The study results imply that there should be genuine reports on the economic performance of the country relying on the specific indexes of poverty measures. There is also a critical need to focus on internal capacities over the reliance on foreign support to achieve poverty alleviation and economic development goals
Determination of Monthly Changes in Some Water Properties of Lake Sureat
Full text linkIn this research, the concentrations of some properties of the water of Lake Sureat were determined during a whole year, such as temperature, pH, electrical conductivity, oxidation and reduction potential, and Polycyclic Aromatic Hydrocarbons (PAHs) to evaluate the possibility of using it for human consumption. Therefore, in this research, water samples were collected from Sureat Lake during the whole year, and extracted and studied quantitatively and qualitatively using the technology of gas chromatography/ spectrometry mass (GC-MS) in order to determine the PAHs concentrations during the seasons of the year. The results showed that the temperature, pH, electrical conductivity, oxidation and reduction potential were within the permissible limits for drinking water, while the total concentrations of PAHs were greater than the permissible value in drinking water sources. They were high in winter, their values were 550.6 ng/L. ∑PAHs recorded a low value in the summer, it was 308.47 ng/L. PAHs with low molecular weights (3-4 rings) were dominant in the water samples during the study seasons, which poses a threat to human life
