  The primary aim of this research study is to assess the factors that effect on service quality and to quantify the customer satisfaction in one of the leading Islamic bank operating in Pakistan. The basic distinction between a conventional and Islamic banking is the documentation and processing of the services provided to the customers. The present study tries to have an insight on the impact of service quality dimension and customer satisfaction using CARTER model. CARTER model is considered as very reliable and valid instrument to measure service quality and customer satisfaction in Islamic banking. Self-administered survey was conducted for data collection from 200 walk-in customer of Meezan Bank. The results of this study indicate a positive relationship between service quality dimensions and customer satisfaction in Islamic Banking.

  The purpose of this research is to explore the relationship between negative customer behaviour and turnover intentions and how emotional exhaustion and job satisfaction will intervene the relationship of negative customer behaviour and turnover intentions of inbound call center agents. It was previously researched that emotional exhaustion negatively effects turnover intentions of employees. However, studies on effects of negative customer behavior were limited. Moreover, the strength of mediating relationship between emotional exhaustion and turnover intentions is also identified in the presence of negative customer behavior. Primary data was collected through self-administered questionnaire from inbound call centers of five telecommunications companies working in Lahore. The selected sample size was 260. By using simple random sampling technique, 232 valid questionnaires with a response rate of 92% were received. PLS-SEM was implemented by using SmartPLS v3.0. The reliability test for independent and dependent variables was calculated. The Validity test was applied on all measuring questions of five research variables. After verifying the assumptions of PLS-SEM, structural model was tested to confirm research hypotheses. Strength of mediator was also tested to measure the effects of job satisfaction. The results of the study revealed that both abusive customer behavior and unreasonably demanding customer behavior both have a negative effect on the emotional exhaustion level of inbound call center agents which will further increase their turnover intentions. Full mediation was also observed when job satisfaction was introduced as mediating variable. It has been further established that abusive customer behavior has a greater negative effect on emotional exhaustion level of inbound call center agents than unreasonably demanding customer behavior. This study explore the ongoing debate on negative customer behavior. This study will not only assist call centers to look into perspectives that were previously ignored but also help them to devise such standing operating procedures that can provide some room for customer service agents to cope up with emotional exhaustion and turnover intentions of inbound call center agents.

  The colonization potential of plant growth promoting bacterial strains (Ochrobactrum intermedium, Bacillus cereus and Brevibacterium sp.) on Triticum aestivum and Helianthus annuus roots. The roots of Triticum aestivum were heavy colonized with Ochrobactrum intermedium and Bacillus cereus as compared to Brevibacterium. Ochrobactrum intermedium mainly colonized the rhizoplane while Bacillus cereus was present both on the rhizoplane and near the root zone. Ochrobactrum intermedium and Bacillus cereus were found to be present both on the rhizoplane as well as near root zones of both crops used (Triticum aestivum and Helianthus annuus) while Brevibacterium was found in the form of groups in the rhizosphere of Helianthus annuus roots. From the results of both crops it was observed that the number of Ochrobactrum intermedium cells were more where some root exudates seen.

  Two chromium resistant bacterial strains i.e. Bacillus sp. S6 and Staphylococcus sp. CrM-3 were used in conjunction with Eichornia crassipes to study the effect of chromate removal from chromium contaminated waste waters. Bacterial strains resulted in reduced uptake of chromate into inoculated plants, which was 17.24 and 11.29% with S6 and CrM-3 respectively, at an initial Cr (VI) concentration of 100 μg ml‾1 as compared to non-inoculated control plants. Different heavy metals (CuSO4, NiSO4, MnCl2 and Pb (NO3) 2) at a concentration of 100 μg ml‾1 were added in chromate-supplemented solution to check their effects on chromate uptake by the plants. At different chromate concentrations the uptake of Cr (VI) into the plants was 28.73, 5.38, 7.15, 12.29 and 15.35% less at an initial Cr (VI) concentration of 100, 300, 500, 1000 and 2000 μg ml‾1 in comparison to metal free condition. Cr (VI) uptake by the Eichornia crassipes was occurred at different pH tested, but maximum uptake was observed at pH 5. Nevertheless the bacterial strains caused some decrease in chromate uptake into the plants but the combined effect of plants and bacterial strains conduce more removal of Cr (VI) from the solution.

  In the present study chromium resistant bacterial strain Bacillus cereus S-6 isolated from effluents of tannery was used for the reduction of toxic Cr (VI) into less toxic Cr (III). It could resist very high concentration of K2CrO4 i.e., up to 40 mg mL-1 on nutrient agar, 25 mg mL-1 in nutrient broth and up to 1.5 mg mL-1 of K2CrO4 in acetate-minimal medium. At an initial Cr (VI) concentration of 100 μg mL-1, the cytosol and membrane preparation of the strain were able to reduced almost 67 and 43% of Cr (VI) within 24 h incubation period while the heat killed cytosol and membrane preparation reduced 24 and 18% within the same time period. At high initial K2CrO4 concentration (500 μg mL-1), the reduction percentage decreased and cytosol reduce 36% and membrane preparation 18% of the total chromium supplied after 24 h. After heat shock these reduction values were 13 and 9%, respectively.

  Twenty-four bacterial strains were isolated from rhizosphere and histoplane of four different arid plants, Trianthema partulacastrum, Rumex dentatus, Chenopodium morale and Coronopus didymus. These bacteria were inoculated to seeds of Vigna radiata var NM-92 which were germinated and grown for 15 days. Majority of strains had inhibitory effect on seed germination (2.2 to 13.0%). The increase in seedling length ranged from 17 to 38% with different inoculations. Bacterial strains TP1, TP3, TP4, RTP4 and RRD1 were the most effective ones for the different growth parameters such as seed length and seed weight whereas the most adverse effects were recorded with the inoculation of TP17 strain. Maximum increase in protein and auxin content was observed with strains TP5 and RCM2, respectively. Peroxidase and acid phosphatase showed maximum activity with the inoculation of strain TP1.

  A chromium resistant bacterial strain S-6 was isolated from chromium-contaminated soil. On the basis of different morphological, biochemical characteristics and 16S rRNA gene analysis the strain was identified as Bacillus cereus S-6. Hexavalent chromium resistance of the strain showed that it could tolerate very high concentration of K2CrO4 both in nutrient medium (25 mg mL-1 in nutrient broth and 50 mg mL-1 on nutrient agar) as well as in acetate-minimal medium (15 mg mL-1). Chromate uptake and reduction studies revealed that the strain Bacillus cereus S-6 not only accumulate but can also reduce large amount of toxic Cr (VI) in to Cr (III). Heavy metals (Ni, Mn, Zn, Cu and Co) at low concentration did not affect the reduction capability of the strain. Strain could also reduce hexavalent chromium in industrial effluents.

  Effects of temperatures (37 and 45°C) in combination with varying pH (6, 7, 8 and 9) after 24 and 96 h of incubation were studied on soluble protein content and protein profile of PY79 (wild type) and sporulation defective mutant strains (5, 19, 96 and 99) of Bacillus strains. These strains were isolated from local polluted environments around Lahore, Pakistan. Soluble protein content is more in PY79 as compared to the defective sporulating mutant strains (5, 19, 96 and 99). In strain 5, it appeared that polypeptides of 55-59 kDa (pH 6, 7 and 8), 50-54 kDa (pH 6, 7 and 8), 45-49 kDa (pH 8), 20-24 kDa (pH 7) and 10-14 kDa (pH 8) were the heat stress proteins. While in strain 99, at high temperature different stress proteins appeared especially at pH 6 (30-34, 25-29 kDa), pH 7 (25-29 kDa), pH 8 (50-54, 30-34 kDa) and at pH 9 (45-49, 30-34, 20-24 kDa). At temperature 37°C, the polypeptides of 55-59 kDa at pH 6, 7 and 9 were observed which disappeared at high temperature.
