Fluorescent pseudomonads have been isolated from halophytes, mesophytes, and xerophytes of Pakistan. Among these, eight isolates, GS-1, GS-3, GS-4, GS-6, GS-7, FS-2 (cactus), ARS-38 (cotton), and RP-4 (para grass), showed antifungal activity and were selected for detailed study. Based on biochemical tests and 16S rRNA gene sequences, these were identified as strains of P. chlororaphis subsp. chlororaphis and aurantiaca. Secondary metabolites of these strains were analyzed by LC-MS. Phenazine-1-carboxylic acid (PCA), 2-hydroxy-phenazine, Cyclic Lipopeptide (white line-inducing principle (WLIP)), and lahorenoic acid A were detected in variable amounts in these strains. P. aurantiaca PB-St2 was used as a reference as it is known for the production of these compounds. The phzO and PCA genes were amplified to assure that production of these compounds is not an artifact. Indole acetic acid production was confirmed and quantified by HPLC. HCN and siderophore production by all strains was observed by plate assays. These strains did not solubilize phosphate, but five strains were positive for zinc solubilization. Wheat seedlings were inoculated with these strains to observe their effect on plant growth. P. aurantiaca strains PB-St2 and GS-6 and P. chlororaphis RP- 4 significantly increased both root and shoot dry weights, as compared with uninoculated plants. However, P. aurantiaca strains FS-2 and ARS-38 significantly increased root and shoot dry weights, respectively. All strains except PB-St2 and ARS-38 significantly increased the root length. This is the first report of the isolation of P. aurantiaca from cotton and cactus, P. chlororaphis from para grass, WLIP and lahorenoic acid A production by P. chlororaphis, and zinc solubilization by P. chlororaphis and P. aurantiaca.

The main aim of this study is to investigate the significant factors influencing driver’s habits and behavior across age groups. As ageing population is increasing rapidly, various age ranges of drivers on the roads require crucial awareness to better educate, manage, and restrain road behaviors. Driving is a complex task in ergonomics perspective that involves human, vehicle and environment. These factors have either advantageous or adverse impact on driving performance. It is crucial to identify and specify requirements necessary for a safe and efficient conduct of driving task. For changes in driving method or design to take place, both young and ageing drivers’ driving tasks need to be examined. Survey on drivers was conducted on 182 drivers (both genders). Participants was divided into two age groups: below 50 years is Younger Group; 50 years and above is Ageing Group. Validated questionnaires used in the study were 1) Driving Habits Questionnaire (DHQ) to evaluate current driving status, general driving practices, driving exposure, dependence on other drivers, and driving difficulty, and 2) Driver Behavior Questionnaire (DBQ) to assess errors, ordinary violations, lapses and aggressive violations. Most of the drivers had difficulty driving in the rain. More than half of the young and ageing drivers reported difficulty driving at night. Failure to notice that pedestrians were crossing was the most frequent error among young and ageing drivers. Age was significantly associated with driving preference during these conditions, rain, right turn in traffic, heavy traffic, rush hour and night driving and have effects on distractions, violations, errors, and lapse of drivers. The presented outcome highlighted the need to design and perform real-time driving experiment observing the on-road driving performance adopting the main elements examined in this study into the task to be assigned.

Clubroot is a devastating disease caused by Plasmodiophora brassicae and results in severe losses of yield and quality in Brassica crops including Brassica oleracea. Therefore, it is important to identify resistance gene for CR disease and apply it to breeding of Brassica crops. In this study, we applied genotyping-by-sequencing (GBS) technique to construct high resolution genetic map and mapping of clubroot resistance (CR) genes. A total of 18,187 GBS markers were identified between two parent lines resistant and susceptible to the disease, of which 4,103 markers were genotyped in all 78 F2 plants generated from crossing of both parent lines. The markers were clustered into nine linkage groups spanning 879.9 cM, generating high resolution genetic map enough to refine reported reference genome of cabbage. In addition, through QTL analysis using 78 F2:3 progenies and mapping based on the genetic map, two and single major QTLs were identified for resistance of race 2 and race 9 of P. brassicae, respectively. These QTLs did not show collinearity with CR loci found in Chinese cabbage (Brassica rapa) but roughly overlapped with CR loci identified in cabbage for resistance to race 4. Taken together, genetic map and QTLs obtained in this study will provide valuable information to improve reference genome and clubroot resistance in cabbage.

<P>Clubroot is a devastating disease caused by <I>Plasmodiophora brassicae</I> and results in severe losses of yield and quality in <I>Brassica</I> crops. Many clubroot resistance genes and markers are available in <I>Brassica rapa</I> but less is known in <I>Brassica oleracea.</I> Here, we applied the genotyping-by-sequencing (GBS) technique to construct a high-resolution genetic map and identify clubroot resistance (CR) genes. A total of 43,821 SNPs were identified using GBS data for two parental lines, one resistant and one susceptible lines to clubroot, and 18,187 of them showed >5× coverage in the GBS data. Among those, 4,103 were credibly genotyped for all 78 F<SUB>2</SUB> individual plants. These markers were clustered into nine linkage groups spanning 879.9 cM with an average interval of 1.15 cM. Quantitative trait loci (QTLs) survey based on three rounds of clubroot resistance tests using F<SUB>2</SUB><SUB>:</SUB><SUB>3</SUB> progenies revealed two and single major QTLs for Race 2 and Race 9 of <I>P. brassicae</I>, respectively. The QTLs show similar locations to the previously reported CR loci for Race 4 in <I>B. oleracea</I> but are in different positions from any of the CR loci found in <I>B. rapa</I>. We utilized two reference genome sequences in this study. The high-resolution genetic map developed herein allowed us to reposition 37 and 2 misanchored scaffolds in the 02–12 and TO1000DH genome sequences, respectively. Our data also support additional positioning of two unanchored 3.3 Mb scaffolds into the 02–12 genome sequence.</P>

Many approaches to improve the transformer oil characteristics have been made by adding nanofillers into the liquids, but it has caused the existence of sedimentation and agglomeration thereby resulting in incompatibility of transformer oil. In view of foregoing, this paper aims to study the impact of cetyl trimethyl ammonium bromide (CTAB) surfactant added with the nanofiller in improving the compatibility and agglomeration issues towards improvement of breakdown voltage (BDV) characteristics of oil nanofluids. This study was carried out by implementing three different percentages of silica (SiO2) and alumina (Al2O3) nanofillers along with CTAB as surfactant into the mineral oil. The breakdown voltage test was carried out accordance to IEC 60156 standard. The results show that the inclusion of 0.1 wt% SiO2 and 0.1 wt% Al2O3 nanoparticles into mineral oil have improved the BDV. Meanwhile, Al2O3 nanofluids with 0.075 wt% CTAB had good impact on BDV but not on SiO2. This case has reverse behavior with the sedimentation which 0.1 wt% CTAB in SiO2 nanofluids has a good response but not the whole in Al2O3 nanofluids. This could be mainly due to the limitation stability of the nanofluids.

However, this study brings forward into 3 main purposes. Firstly, to explore the development of financial institutions, products and regulatory reforms. Secondly, to find out the performance of Islamic banking institutions. Lastly, to identify the problems, challenges and Islamic banking future prospects. Research design, data, and methodology - An in-depth literature review was carried out to fulfil the research objectives. Results - The findings point out the basic problems of Islamic banking industry in UK such as unfavorable regulatory environment, unfamiliarity with the Islamic Banking System, lack of portfolio management, absence of liquidity instruments, in need of professional bankers, and blending of approach of Islamic scholars with the approach of the conventional bankers. The findings also indicate that there are greater opportunities in the UK for development and growth of Islamic financial system because Muslim community is eager to take financial products. Conclusions - It is hoped that issues pertaining to Islamic banking products can be resolved through consensus of Shariah scholars. There is need to educate the Muslim community about Islamic financial products and service.
