The selected siliciclastic Siwalik Group display various facies in a fluviatile environment, with different lithologies, and sedimentary features. The petrographic studies of Siwalik Group delineate different microfacies including feldspathic litharenite, litharenite and sub arkose. The provenance study of sandstones depicted the terrane of dissected arc and recycled orogeny, indicating that the detritus was received from sedimentary, metamorphic, plutonic and volcanic rocks from the northern domain of Indian Plate, Karakoram Ranges and Kohistan Island arc. The Siwalik sandstone also contains heavy mineral assemblage such as tourmaline, garnet, epidote, hornblende and chlorite. This heavy detritus assemblage depicted that the deposits were received from metamorphic and igneous origin. A modified dynamic depositional stages of the Siwalik Group with respect to Himalayan orogeny is further built using outcrop data, microfacies and heavy minerals analysis. According to this concept, the group was deposited along Himalayan uprising and thrusting, on the depository in targeted area. The Siwalik Group depicted different phase of Himalayan tectonics and these molasse sequence were deposited in a subsiding foreland basin under the conditions of rapid erosion and quick deposition.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75392587","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}

Its important uses in different industries include, pharmaceutical, perfumery, and food industries that manifest higher flower yield. Therefore, response of Gruss-an-Taplitz to foliar application of chitosan (Ct) solution (0, 2.5, 5, 7.5, 10 mg L-1), was evaluated in an experimental field. Ct treatment had significant effects on studied parameters, including plant growth, pigments, enzymes, and gaseous exchange. This experiment was laid out under Randomized Complete Block Design (RCBD) using three replications per treatment. Ct (7.5 mg L-1) significantly improved growth, in terms of higher leaf area (20.37%), plant height (20.19%), number of flowers (55.51%), flower weight (34.64%) and flower diameter (33.78%) as well as enhancing relative water contents (27.38%) with respect to control. Chlorophyll a (54.60%), Chlorophyll b (12.13%), Carotenoid (8.36%) and anthocyanins (17.09%) were also increased at 7.5 mg L-1 Ct, which showed higher photosynthetic pigments as compared to control.

In this work, nine fastgrowing microalgal strains isolated from the Arabian/Persian Gulf coastal waters of Kuwait were evaluated for their potential as biofuel feedstocks. 18S rRNA gene sequencing showed that the strains belong to five different genera, namely, Chlorella, Nannochloris, Scenedesmus, Tetraselmis, and Nannochloropsis. In terms of the total lipid content, in comparison to the other strains, Tetraselmis sp. KUBS13G and Tetraselmis sp. KUBS16G displayed higher lipid contents of 29.56% dry weight (DW) and 26.13% DW, respectively, which were dominated by palmitic and oleic acids. Fuel properties calculated from the fatty acid methyl esters (FAMEs) by empirical equations were compared with EN14214 (European) and ASTM D6751-−02 (American) biodiesel standards. Multicriteria decision analysis (MCDA) methods, such as the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) and Graphical Analysis for Interactive Assistance (GAIA), were used to select suitable microalgae for biofuel feedstock based on their biodiesel fuel properties. Overall, the results suggested that the indigenous microalgal strain Tetraselmis, in particular Tetraselmis sp. KUBS37G, and Scenedesmus sp. KUBS17R are the most suitable strains for biofuel feedstock owing to their improved fuel properties, such as density (ρ) (0.88 g cm−3), low kinematic viscosity (3.1 mm2 s−1), high cetane number (54 and 56, respectively), high oxidation stability (14.6 hr and 14.8 hr), and cold-filter plugging point (1.0°C and -6.1°C).","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75497330","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}

Globally, there is an alarming rise in the prevalence of psychiatric conditions. Genetic and environmental factors are involved in the pathophysiology of these disorders, but molecular underpinning is still elusive. Cholinergic dysregulation is one of the aetiology of psychiatric condition. This study was aimed to assess the status of hydrolyzing enzyme of cholinergic neurotransmitter, acetylcholinesterase (AChE) from blood and investigate the possible association of a single nucleotide polymorphisms in 3'UTR region of ACHE (rs17228602) with predisposition to psychiatric disorder. Methods: Ninety-five confirmed psychiatric and one hundred thirty healthy individuals were recruited for the study with due consents. AChE was determined by Elman’s method. SNP was studied by polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) and sanger sequencing on DNA samples. Results: The results showed notably reduced AChE in psychiatric cohorts with statistical significance (p≤0.05). Genotype and allelic association of the examined SNP was observed with the risk of psychiatric condition in patients.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86457143","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}

However, the correlation between unstable diabetes and these hormones has little or no information in the literature; hence, the focus of this study. Diabetes was induced with a single intraperitoneal injection of 150 mg/kg of freshly prepared alloxan. Twenty five adult male Wistar rats (weight 120-150 g) were used in this study. Alloxan was administered to 20 rats and 5 rats served as control. Alloxan-administered rats were further divided into two groups. One group (diabetic rats) was used as diabetic control and the other group served as reversed diabetic, which contained rats whose fasting blood glucose was confirmed to be normoglycemic post-diabetic. All rats were maintained on normal rat feed and water ad libitum and were monitored for 14 days. Blood glucose was monitored at intervals of 7 days after basal (before diabetes induction) and day 1(diabetes confirmation) values had been noted. Sex hormones: Luteinizing hormone (LH), follicle stimulating hormone (FSH), and estrogen (E) as well as thyroid hormones: Triiodothyronine (T3), tetraiodothyronine (T4) and thyroid stimulating hormone (TSH) were assayed after 14 days. Alloxan caused alteration in blood glucose levels of both diabetic and reversed diabetic groups. T4 level was lowered significantly in both diabetic (11.32 ± 0.26 μg/ml) and reversed diabetic (11.00 ± 0.16 μg/ml) groups in relation to the control. Other assayed hormones were not different significantly from the control. These findings indicate that influence of diabetes on these hormones may not be dependent on glucose gradation.","PeriodicalId":49933,"journal":{"name":"Kuwait Journal of Science & Engineering","volume":"10 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72449464","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}

An analysis of molecular variance depicted higher genetic diversity (80%) within the populations and lower (20%) among the populations. The low genetic diversity among the inland and coastal populations might be due to fragmentation and long physical distances. The dendrogram and principal component analysis clearly distinguished the genotypes of the two populations into two distinct clusters.

The study was aimed to inspect phenotypic detection and antimicrobial resistance pattern of extended spectrum beta lactamase- and metallo beta lactamase-producing P. aeruginosa strains. Clinical specimens (n=220) were collected from indoor patients with ear discharge were inoculated on suitable culture media. Antimicrobial resistance pattern of all isolates was investigated employing Kerby-Bauer disc diffusion method. Double-disc synergy test and imipenem-EDTA test were used respectively to detect ESBL- and MBL-producing strains. From n=220, n=37 (16.82%) clinical specimens confirmed the growth of P. aeruginosa. In comparison to female (43.24%), male population (56.76%) was more prevalent. Out of n=37 positive cases, n=16 (43.24%) strains were detected as ESBL producers, while n=07 (18.92%) as MBL producers. Cefotaxime (100%) was found the most resisted antibiotic by isolates, followed by aztreonam (91.89%), gentamycin (86.49%), ceftriaxone (83.78%) and tazobactam/piperacillin (64.87%), while the lowest resistance was observed against imipenem (21.63%) and meropenem (51.36%). Furthermore, ESBLproducing strains revealed high resistance against cefotaxime (100%), ceftriaxone (93.75%), and carbenicillin (87.5%), while MBL-producing strains were completely resistance to imipenem, meropenem, cefotaxime and carbenicillin, followed by gentamicin (85.71%), amikacin aztreonam, ciprofloxacin and tazobactam/piperacillin (71.43% each). Our study concluded that strains of P. aeruginosa producing ESBL and MBL enzymes were mostly resistant to the drugs of choice, which puzzle the physicians to treat infections caused by P. aeruginosa.
