Sustainability practices and business strategies in the recycling industry of Bangladesh : a study on Rashed & Brothers
No full textThe present study explored the sustainability practices employed by Rashed and Brothers, a prominent entity in Bangladesh's recycling business. In its attempt to create opportunities, it has focused on waste reduction, resource utilization efficiency, and environmental impact mitigation.
This study primarily employed a quantitative methodology and involved 20 actively employed employees directly engaged in the organization's everyday activities. Pie charts have been used to provide a visual representation of staff members' perspectives regarding sustainability challenges. The results demonstrated that Rashed & Brothers achieved a degree of success in several sustainable business initiatives, despite ongoing challenges in employee training and advanced recycling efforts. Moreover, it highlighted that the implementation of new technologies and a more comprehensive connection with national agenda items, such as the National 3R Strategic Approach, might further enhance these concepts.
The objective of the thesis was to establish a sustainable culture by implementing certain proposals: improving employee training and utilizing sophisticated technologies for recycling and communication. This research sought to elucidate the notion of corporate sustainability within Bangladesh's recycling sector. It also furnished Rashed and Brothers with other concepts that may be implemented to improve their environmental initiatives. It underscored the significance of ongoing development and established a foundation for further investigation into policy interventions, technological and economic advancements, and the socio-economic impacts related to the industry
Grammatical significance in haron hashim rashed poems
No full textIt aims This research to study the grammatical significance in poems haron Hashim rashed from where prefixing ,forestallment , deleting additional and the composing structures the importance of this study relates to studying grammar in term of meaning; so it gives freshness and leanness. it also gives the poem seriousness and facetiousness.
In this study I depend on integrative approach, the historical approach of the poet`s life and the descriptive analytical approach. I explain the meaning of significance grammaticalness then extract the significances from haron Hashim rashed poems and the statistics approach; so I compute the grammatical significance in the poet`s poem.
The most important results that I found in this study are the following: first the prefixing and forestallment have many significance the prefixing has the meaning of attention and there search shed alight on that deleting is linguistic phenomenon haron Hashim rashed poem and has abbreviation significance. The research also found that additional letters have two significances: the first one is moral significances, which asserts on meaning. The second one is verbal significances, which focuses on decorating the pronunciation.يهدف هذا البحث إلى دراسة الدلالة النحوية في ديوان هارون هاشم رشيد من حيث: التقديم والتأخير، والحذف، والريادة، والتراكيب الإنشائية. وتعود أهمية هذه الدراسة أنها تدرس النحو على أساس المعنى، فتعطيه نداوة وطراوة، وتكسبه جدة وطرافة.
وقد اتبعت في هذه الدراسة المنهج التكاملي، فاستخدمت المنهج التاريخي في دراسة حياة الشاعر، والمنهج الوصفي التحليلي، فبينت المقصود بالدلالة النحوية ومن ثم استخرجت الظواهر الدلالية من ديوان هارون هاشم رشيد ، والمنهج الإحصائي، فأحصيت الدلالات النحوية الواردة في ديوان الشاعر.
ومن أهم النتائج التي توصلت إليها الدراسة أن الأسلوب التقديم والتأخير دلالات متعددة، أهمها: اختصاص المتقدم بالعناية والاهتمام، وأظهر البحث أن الحذف ظاهرة لغوية في ديوان هارون هاشم رشید، لها دلالة الإيجاز والاختصار، وكذلك كشف البحث أن الحروف الزيادة دلالتين: الأولى: دلالة معنوية: تدل على تأكيد المعنى، والثانية: دلالة لفظية: يدخل فيها تزيين اللف

Antimicrobial and synergistic effect of Moroccan native Argania spinosa essential oil for modulating of antibiotics resistance
No full textIn this study, the chemical composition and antimicrobial activity of the essential oil (EO) extracted from leaves of the Moroccan endemic plant Argania spinosa were investigated for the first time, to the best of our knowledge. In addition, the EO antimicrobial activity was evaluated in combination with two known antibiotics (ciprofloxacin and fluconazole), in order to ascertain possible synergistic effects. The chemical composition analyzed by GC/MS showed that A. spinosa EO was characterised by the abundance of geranyl acetate (19.18%), methyleugenol (10.98%), linalyl acetate (10.59%) and eucalyptol (8.49%), and monoterpene hydrocarbons was the major class. EO showed an antimicrobial potential against all tested microorganisms. The highest activity was recorded against Gram positive bacteria and yeasts with MICs ranging from 7.75 to 15.5 mg/mL and from 3.88 to 7.75 mg/mL, respectively. The Gram negative bacteria were the most resistant with MICs of 31 mg/mL. The mixture of EO at sub-inhibitory concentrations with conventional drugs exhibited a significant decrease in their individual MICs from 4 to 32 fold. The highest level of synergy was observed for ciprofloxacin against Staphylococcus aureus, Bacillus subtilis and Escherichia coli. Despite the antimicrobial activity of A. spinosa EO is weak, the results of the current study suggest a potential synergy between EO and antibiotics in the goal to modulate drug resistance

Also Part of this thesis has been published in the Analytical Biochemistry JournalTyrosinemia type-I (Hereditary Tyrosinemia; HT-I) is an autosomal recessive inherited metabolic disorder. It is the most serious and common of the genetic defects in tyrosine catabolic pathway. The disorder results in extensive clinical and pathological manifestations involving mainly the liver, kidney, and peripheral nerves. HT-I is caused by deficient fumarylacetoacetate hydrolase (FAH) activity, which leads to the accumulation of succinylacetone (SA), the key marker of the disorder, in the urine and plasma of affected individuals. As HT-I may now be effectively treated and early diagnosis has proven to yield a better clinical outcome, its inclusion in newborn screening programs is being considered in many countries.
Current methods for the detection of the disease are based on the measurements of the SA in urine, plasma, and amniotic fluid by gas chromatography mass spectrometry (GC-MS). A semiquantitative spectrophotometric assay, whereby inhibition of δ-aminolevulinic dehydratase by SA in dried blood spot (DBS) is used to rule out the disorder, however possible problems with this strategy is false-positive results if the DBS was exposed to high temperatures, in cases of hereditary δ-ALA dehydratase deficiency, or in cases of lead exposure via cord blood. The disease can be detected by determining FAH deficient activity in human liver, lymphocytes and fibroblast. However, the demonstration of FAH activity alone in any tissue may not be conclusive for the diagnosis of HT-I due to the presence of pseudodeficiency gene of FAH that results in enzyme activity nearly as low as the HT-I gene.
A stable isotope dilution liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the determination of SA in urine for the diagnosis of HT-I was developed, where the 15N-5(3)-methyl-3(5)-isoxazole propionic acid is used as an internal standard (IS). To urine samples, hydroxylamine HCl was added under acidic condition and heat to yield the methyl-isoxazole propionic acid derivative; this was followed by ether extraction and then the addition of butanolic HCl to give the butylated derivative. The butyl isoxazole derivatives of SA and its IS were detected and quantified using positive-ion Electrospray LC-MS/MS with selected reaction monitoring. The turn around time between injections was 10 min. Calibrations were linear over the range of 0.0633-63.3 μmol/L. The intra- and inter-day assay variations were less than 7%. Mean recoveries of SA at three different concentrations ranged from 96% to 109%. During the course of this study we identified 12 new patients with HT-I and applied this method to follow-up the treatment of four of these patients
