Adsorption of nickel on electric arc furnace slag: batch and column studies

The ability of electric arc furnace slag (EAFS), a by-product of the steel industry to adsorb nickel [Ni(II)] from an aqueous solution, was investigated by both batch and column operations. The characterization studies showed the mesoporous nature of EAFS with dominance of acidic sites. The adsorption was found to be dependent on the adsorbent dosage, contact time, the pH, and initial metal ion concentration. Optimum Ni(II) uptake was 160.92 mg/g at 1000 mg/L initial concentration with equilibration time 216 h. Adsorption follows the pseudo-second-order kinetics model. Linear and non-linear isotherm models revealed the applicability of the Langmuir model confirming monolayer adsorption. Both the column bed capacity and the exhaustion time increased with increase in bed height. The saturation time was found to increase from 42 to 46 h with a decrease in the flow rate from 15 to 5 mL/min. The bed depth saturation time and Thomas models were evaluated. The experimental breakthrough curves agreed well with the predicted model

Effect of Daily Chewing Soft Buds and Leaves of Catha edulis (Khat) on the Antioxidant Defense System and Oxidative Stress Markers in Blood

Catha edulis (Khat) is one of the major economic, social and health problems in Yemen. This paper aimed to study the effect of Khat on the oxidative status of Khat chewers by measuring the levels of enzymatic and non-enzymatic antioxidant as well as lipid peroxidation. The results exhibited significant reduction in erythrocytes superoxide dismutase (SOD, EC: 1.15.1.1), and catalase (CAT, EC: 1.11.1.6) in Khat chewers, in addition to elevation of serum glutathione-S-transferase (GST, EC: 2.5.1.18). Furthermore, non-enzymatic antioxidants glutathione (GSH) and vitamin C were significantly reduced (p < 0.001; p < 0.015), whereas malondialdehyde (MDA) was significantly elevated (p < 0.001). The depletion of GSH and vitamin C along with MDA elevation in Khat chewers compared with control reflects the obvious oxidative status, a result of enormous reactive oxygen species (ROS) formation, leading to membrane damage. ROS possibly induced by active components of Khat or by pesticides added to the Khat tree. In addition, the reduction of SOD and CAT is indicative to cellular proteins damage which occurred by ROS. As well, the elevation of GST may due to a leakage of cellular GST to blood stream; this implies that GST active site was not affected. This study concludes that daily chewing Khat for long period certainly induce ROS production, leading to oxidative toxicity. Both enzymatic and non-enzymatic antioxidants are involved in the protection against this toxicity. People who habitually chew Khat for long term will be susceptible to the oxidative toxicity; therefore, they recommended giving up of Khat chewing

[Sa'id Hawwa's Writing Method on Islamic Family Through His Work Qawanin Al-Bayt Al-Muslim] Metod Penulisan Sa‘Id Hawwa Berhubung Kekeluargaan Islam Menerusi Karyanya Qawanin Al-Bayt Al-Muslim

Islam is a religion that put family well-being as one of its priorities. The discourse regarding attitudes and laws in family has long been explained in great length in Islamic familial literatures. However, the focus of the discourse usually inclines towards juridical aspect and general values. It is quite uncommon to find a writing that is authored in policy form which can be utilised as a guideline by the family. Sa‘id Hawwa is a prominent Muslim preachers who was famous for his methodological approach in writing about familial matters. This study aims to run a content analysis on Sa‘id Hawwa’s methodological writing in his Qawanin al-Bayt al-Muslim. This qualitative study utilises inductive, deductive and comparative method. This study finds that Sa‘id Hawwa’s approach very relevant to be applied in other writings on family. This is beacause he uses relax writing style, simple phrasings, avoiding denominational issues and moderate stand when discussing Sufism and denominational indifferences. Said Hawwa also explains using examples and he offers solutions besides using a narrative approach of storytelling based on his own experience. Not only is this approach proper with the need of the today’s society, it should be considered as a guideline for modern preachers in addressing the people they call.

A GIS-based emission inventory at 1 KM -1KM spatial resolution for particular matter (PM10) in Klang Valley, Malaysia

Traffic has greatly contributed to the socio-economic development as well as its inherent environmental impacts. This study estimated the emission of PM10 from the exhaust and nonexhaust, particularly from the use different type of vehicles in Klang valley region. The total PM10 emission from the region was calculated based on US-EPA and the EEA methodologies. Arc GIS is one of the most suitable methods to estimate the total PM10 emission and split between different vehicle types as it is determined by the kilometer covered for each vehicle category. The inventory is further used for traffic account, activity data and a domain size of 50 km×50 km, with cell resolution of 1km × 1km to spatially disaggregate these emissions. The results show that nearly 54% of the PM10 emitted in the region emitted from cars. The results also revealed that nearly 61% of the PM emissions emitted from exhaust. Exhaust and Non-exhaust PM10 emissions are higher in the central part of the Klang Valley, an area with higher volume of vehicles

A REVIEW ON COMPARATIVE STUDY BETWEEN THE PHYSICOCHEMICAL AND BIOLOGICAL PROCESSES FOR PARACETAMOL DEGRADATION

Paracetamol has emerged as one of the most frequent pharmaceuticals that found in natural waters and even in drinking water due to its high consumption and therefore deserves a review on the possible treatments for its remediation. The purpose of this review work is to give a compare between the physicochemical and biological processes for removing paracetamol from aquatic environment. Different types of processes are described in this review: from physicochemical process such as membrane filtration, chlorination, activated carbon, and advance oxidation, which applied for pracetamol degradation, to biological process such as microbial, membrane bioreactor, aerobic and anaerobic degradation, which are more recently focused on the degrading paracetamol. Physical processes, that eliminate the pollutant without degrade it, are not efficient enough to completely remove paracetamol from aquatic environment. While the chemical processes that are shown to be fast and efficient to remove paracetamol substance possess some drawbacks representing in high operational cost which make them not a desirable choice for treating wastewater. Biological process receives currently a significant attention for the removal of pollutants because it is found to be the most efficient technology which can be applied in degrading different pollutants. Regardless of its disadvantages, it has been found more efficient on degrading the paracetamol when compared to physicochemical processes. Furthermore, the combination between the biological and physicochemical processes overcomes all of the problems of processes that presented during treatment. Also, the combined processes improve the paracetamol degradation rate and reduce the treatment costs. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Peer Review History: Received 1 April 2017; &nbsp;&nbsp;Revised 10 May; Accepted 13 May, Available online 15 May 2017 Academic Editor: Dr. Jennifer Audu-Peter, University of Jos, Nigeria, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

BIODEGRADATION OF PARACETAMOL BY NATIVE FUNGAL SPECIES INHABITING WASTEWATER OF A PHARMACEUTICAL FACTORY IN SANA’A, YEMEN

Objectives: Paracetamol has emerged as an important environmental contaminant due to its extensive use. The purpose of this work was toisolate, identify, and characterize fungal species able to degrade paracetamol from pharmaceutical wastewater effluent at Sana'a City, Yemen. Methods: The fungi were isolated and purified from wastewater samples using enrichment and selective media. The isolated fungi were identified according to phenotypic characterization. Two species of isolated fungi were able to utilize the paracetamol as the sole of carbon and energy sources. These fungi were designated as F1 and F2 and identified as Aspergillus niger and Fusarium oxysporium, respectively. Optimum temperature and pH for growth of both species were 25˚C and 6.0, respectively. Also, the biodegradation of paracetamol was influenced by glucose concentration. Results: &nbsp;F1 and F2 were able to degrade 35.7% and 26.1% of 1000 and 2000 mg/l, respectively, paracetamol in 60 days. This is the first report on the ability of Aspergillus niger and Fusarium oxysporium to degrade paracetamol. Conclusion:&nbsp; The reported findings highlight the potential use of the isolated microorganisms for treatment of paracetamol-contaminated wastewater.

Upper Gastrointestinal Malignancy Among Dyspepsia Patients in Cipto Mangunkusumo Hospital Jakarta

Background: Upper gastrointestinal (GI) Malignancy was still a health problem in all over the world. The prevalence of the upper GI Malignancy vary among Asian countries. Data from Indonesia was scarcely reported. The aim of this study is to determine the frequency of upper GI Malignancy among dyspepsia patients who underwent esophagoduodenoscopy (EGD) procedure. Method: This is a retrospectives study from subject with dyspepsia that had underwent upper GI endoscopy at the Department of Internal Medicine Cipto Mangunkusumo hospital from January 2005 to December 2007. All complete data from medical report and histopathology appearance will be recorded. Results: Out of 2,116 subjects underwent endoscopy due to dyspepsia, 110 (5.19%) subjects was diagnosed as cancer. This upper GI Malignancy consisted of gastric cancer in 63 (2.97%) cases, esophageal cancer 32 (1.51%) and duodenal cancer 15 (0.71%). The mean ages of the subjects was 53.36 ± 10.97 years, age less than 45 years was 20 (18.20%) subjects, more than 45 years was 90 (81.18%), male 71 (64.50%) subjects, female 39 (35.50%). Most of them had alarm signs 96 (87.30%). Histopathology finding showed adeno-carcinoma in 75 (68.20%) cases, signet ring cell carcinoma in 14 (12.70%), squamous cell carcinoma in 8 (7.30%), others in 13 (11.80%). Out of 59 gastric cancer, 48 (76.20%) cases was located at distal part while the rest 11 (17.50%) cases was located at the proximal gaster, and 4 (6.30%) in diffuse. By the ethnics founded Javanese 37 (33.60%) subjects, Betawinese 22 (20.00%), Sundanese 12 (10.90%) and Batak 13 (11.80%). Conclusions: Upper GI Malignancy was found in five percent of subjects with dyspepsia who undergo colonoscopy. The three most frequent Malignancies were gastric carcinoma, esophageal carcinoma, and duodenal carcinoma respectively. Most of gastric adenocarcinoma was located at distal stomach

Effect of Female Sex Hormones on Cardiorespiratory System: Theoretical Review

This study aimed at analyzing the effect of the female sex hormones upon  the cardiorespiratory system. And the results showed that the cardiac output measurement showed no significant increase during both phases of menstrual cycle before exercise but there was an insignificant increase soon after exercise owing to sympathetic over activity. The observed increase in the peripheral blood flow during mid-follicular phase before and after exercise revealed that influence of estrogen increases the arterial distensibility. The observed increase in the respiratory efficiency test during early luteal phase before and soon after exercise revealed the influence of progesterone, which is considered to be a potent stimulator of respiration, and added up effect of hormones and exercise-induced changes
