Influence of Hudiara Drain Water Irrigation on Trace Elements Load In Soil And Uptake By Vegetables
MT Yamin, N Ahmad
Journal of Applied Sciences and Environmental Management , 2007,
Abstract: The rapid urbanization in the cities and increasing load of population generating lot of problems for maintaining environment. The sewage and industrial effluent generated by human settlement are disposed of directly in to nearby rivers / water bodies and agricultural fields. This polluted water not only contains organic matter and crop nutrients but also some toxic metals. The water of these channels may become a potential source of diseases and contaminate our natural resources. In Pakistan it is a common practice to use industrial and sewage effluents for raising crops. Continuous use of such effluent could result in accumulation of metals to such a concentration that may become phytotoxic and eventually hazardous to animal and human health. One such example is the Hudiara drain; a transboundary channel originates from India and enters in Pakistan at village Laloo. Farmers of nearby locality are using the untreated waste water for raising the crops and vegetables. This practice is being done at more than 4000 acres of cultivated area along the Drain by lifting the drain’s water through electric pumps, peter engines and tractor driven devices. The density of tubewells is 7 pumps per kilometres for irrigating the farmer’s fields and it is increasing day by day. Three points were selected for sampling the vegetables along the 54.6 km stretch of drain, each at head, middle and tail. Soil samples were taken before sowing and after the harvesting of crops. Plant samples were collected at maturity from all the monitoring points. At each location samples were collected at four nearby sites for detail and representative analysis. During the growing period of crop regular monitoring of Hudiara drain was done for water quality parameters. It was found that metal ions concentration in the vegetables was higher as specified in the standards. Similarly water quality of drain showed increasing level of Residual Sodium Carbonate (RSC), Sodium Adsorption Ratio (SAR) and Electrical Conductivity (EC) as recommended in the water quality criteria. Dissolved Oxygen (DO), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) requirements of Drain water were also found higher than the National Environmental Quality Standards (NEQS) established under the Pakistan Environmental Protection Act, 1997. It was concluded that continuous use of untreated drain’s water is not suitable for raising agricultural crops due to its consequences on human health and soil environment.
Chronic suppurative otitis media in Gombe, Nigeria
BM Ahmad, MT Kudi
Nigerian Journal of Surgical Research , 2003,
Abstract: Background: Chronic suppurative otitis media is a common problem in developing countries and it is necessary to determine the local epidemiology for adequate treatment. Method: A retrospective study of 206 patients with chronic suppurative otitis media (COSM). Results: All the patients presented with ear discharge and tympanic membrane perforations while 57 (27.7%) had associated nasal symptoms. The most common tympanic membrane perforation was the central type seen in 125 (60.7%) of the patients. Of the 206 patients studied, using standard microbiological methods, 87.4% of patients had positive bacterial culture. These were staphylococcus aureaus 37.8%, pseudomonas aeruginosa 28.9% and proteus species 18.3%. Children within the age group of 0 – 10 years were the most affected. Antibiotic sensitivity result showed that gentamicin (88.5%), cefuroxime (63.7%) and cephalexin (61.7%) were active against majority of the isolates. Conclusion: Gentamicin, cefuroxime and cephalexin are recommended as first line antibiotics in the treatment of COSM. Other modalities of treatment are further highlighted. Key Words: Chronic otitis media, tympanic membrane perforation, Gombe Nigerian Journal of Surgical Research Vol.5(1&2) 2003: 120-123

Ahmad MT,Leong CK,Surrun SK
Indian Journal of Physical Medicine and Rehabilitation , 2010,
Abstract: The term dysautonomia is used when there is aderangement in the reflex mechanisms of the limbicsystem resulting in improper control of pulse and bloodpressure and even syncope sometimes. Cervicalmyelopathy may be complicated by dysautonomia andmay rarely cause syncope; however, prolonged coma asa result of autonomic dysfunction in traumatic cervicalmyelopathy has not been described in the literature. Wedescribe two patients with cervical myelopathy withdysautonomia who had prolonged coma, one of whomhad to intubated multiple times and kept on ventilatorysupport.
Convexity-Preserving Scattered Data Interpolation
Abd. Rahni Mt. Piah,Azizan Saaban,Ahmad Abd. Majid
Matematika , 2008,
Abstract: This study deals with constructing a convexity-preserving bivariate C1 interpolants to scattered data whenever the original data are convex. Sufficient conditions on lower bound of Bezier points are derived in order to ensure that surfaces comprising cubic Bezier triangular patches are always convex and satisfy C1 continuity conditions. Initial gradients at the data sites are estimated and then modified if necessary to ensure that these conditions are satisfied. The construction is local and easy to be implemented. Graphical examples are presented using several test functions.
Using magnetic resonance to diagnose breast cancer and predict therapeutic response
MT Nelson
Breast Cancer Research , 2004, DOI: 10.1186/bcr834
Abstract: Women scheduled for a breast biopsy or scheduled to CT were recruited for our study. All studies were done with a 4 T MRI/MRS scanner. A baseline scan was done prior to the start of CT and 24 hours after CT. Suspicious lesions were identified and measured with a fat-suppressed high-resolution 3D FLASH image (Gd-TPA, 0.1 mmol/kg). Concentrations of tCho were quantified [3]. Each scan was interpreted by evaluation of lesion size, architecture, signal intensity, and tCho.Twenty-six out of 69 patients had infiltrative ductal carcinoma, 10/69 patients had infiltrative lobular carcinoma, 3/69 patients had ductal carcinoma in situ, 1/69 patients had lobular carcinoma in situ, and 29/69 patients were found to have benign breast lesions. Eight patients have been through CT. Tumor response was seen in six patients. MRS could detect decreased [tCho] within 24 hours after CT. In the six patients with decreased [tCho] at 24 hours, 100% showed diminished tumor size measured by MRI after 9 weeks of CT. However, the two patients with sustained or elevated [tCho] at 24 hours failed to have response to CT.Based on these results, we expect that the addition of MRS to MRI will provide a noninvasive technique for determining whether a breast abnormality is benign or malignant. Furthermore, the [tCho] measured at 24 hours appears to predict response to CT.
The methylenetetrahydrofolate reductase gene variant (C677T) in risk mothers with Down syndrome among Saudi population
MT Tayeb
Egyptian Journal of Medical Human Genetics , 2012,
Abstract: This unreeled study aimed to examine the relationship between the genetic polymorphisms C677T in MTHFR gene and mapped this figure with other ethnic populations. The present study examined 70 Saudi females (30 mothers with DS children plus 40 healthy mothers who gave birth only to healthy children) for C677T genotypes using restriction fragment length polymorphism (RFLP) of the amplified genomic DNA. The frequencies of the combined mutant genotypes CT and TT in the MTHFR gene were modestly represented in the case mothers compared to that in controls (33% vs. 35% and 13% vs. 10%) with no significance (OR 1.1, 95% CI, 0.41–2.77, p= 0.91). The frequency of the mutant 677T allele was 28% in the case mothers and plotted as a moderate value with different ethnic populations. The present study concluded that there was a null association between the common C677T polymorphism and the increased risk of Down syndrome, but the T allele slightly supported the increase of this maternal risk. The intermediacy to previous reports may probably be due to the small sample size, gene-nutritional-environmental factors, or the consequences of much social intermarriage between some Asian, Arab peoples and the Saudi community.
Association of the UCP2 –866G/A polymorphism with type 2 diabetes and obesity in Saudi population
MT Tayeb
Egyptian Journal of Medical Human Genetics , 2009,
Abstract: Background: Diabetes mellitus is emerging as a major public health problem allover the world particularly Saudi Arabia. Recent studies reported that Uncoupling Protein 2 (UCP2) was associated with obesity and type 2 diabetes (T2D). Aim of the Study: This study was conducted to clarify the contribution of polymorphism in UCP2 in obesity and T2D in the Saudi population. Subjects and Methods: The distribution of the –866G/A polymorphism was examined in a case-control study including samples from 110 obese patients, 81 T2D patients, 96 obese-T2D patients and 100 healthy unrelated Saudi subjects. The –866G/A polymorphism were determined by using PCR/RFLP (polymerase chain reaction/restriction fragment length polymorphism) techniques. Results: The results of this study showed that the frequency of the GG genotype was significantly higher in both obese and T2D patients (p-value= 0.0001, p-value= 0.014, respectively) compared with healthy control. The G allele was significantly associated with increase risk of obesity (odd ratio, OR: 3.3; 95% confidence interval, CI: 1.37-7.98), but not with T2D (OR, 1.97; Cl, 0.80-4.87). In obese-T2D patients group, no significant correlation with –866G/A polymorphism (p= 0.067; OR, 1.21; Cl, 0.25-2.80). This unreeled study suggested that the G allele of UCP2 –866G/A polymorphism was related to obesity, which indicated the possible role of this polymorphism in causing metabolic syndrome. Conclusion: This study concluded that the G allele of UCP2 –866G/A polymorphism might be related to obesity and T2D which might be used as a predictive marker for obesity and T2D. Key Words: T2D, Obesity, Uncoupling protein 2 (UCP2) gene, –866G/A polymorphism, Saudi population.
Desulphurization of Transportation Fuels by Per-Formic Acid Oxidant Using MoOx Loaded on ZSM-5 Catalyst  [PDF]
Waqas Ahmad, Imtiaz Ahmad
Journal of Power and Energy Engineering (JPEE) , 2017, DOI: 10.4236/jpee.2017.512011
Abstract:
Desulphurization of model and real oil samples was investigated using performic acid as oxidant assisted by air as co-oxidant. The catalysts used were Mo-oxide supported on ZSM-5 zeolite, which was synthesized in the laboratory and characterized by FT-IR, XRD, SEM and SSA analysis. In case of model oil, the optimum condition determined for complete oxidation of all the model compounds including thiophene, DBT and 4,6-DMDBT were; 60?C, 60 min, ambient pressure and air flow rate of 100 mL/min. The oxidation reactivity decreased from 4,6-DMDBT to DBT and thiophene, which was found to follow pseudo first order kinetics. The real oil sample used in the study included untreated naphtha (NP), light gas oil (LGO), heavy gas oil (HGO) and Athabasca bitumen (Bit.). In case of NP and LGO the sulfur removal of above 78% was attained whereas in case of HGO and Bit. samples about 60% of desulfurization was achieved.
LOCAL WISDOM IN JAVA’S ARCHITECTURE (STUDIED IN NATURE, TECHNOLOGY AND HUMANITY)
Murni Rachmawati, MT,Andy Mappajaya, MT
Academic Research International , 2012,
Abstract: The 21st century architecture is faced with three major issues: nature, technology and humanity. Java architecture which derived from the philosophy of Java was known by its local wisdom. However, it is not known whether the wisdom is related with the issues of the 21st century or not. For that conducted the study which obtains the position of Java’s wisdom when viewed from the three issues: the handling of nature, technology and humanity in architecture. The data was derived from literatures and field study. The method used is criticism and logical argumentation. The final result is the suitability and unsuitability of Java’s wisdom with the issue of the 21st century. Java’s wisdom actually suits the three issues because they already had their own wisdom which able to handle these issues, but not all writes on literatures.
Starter dietary lysine level and strain cross effects on performance and carcass traits of broiler females
Corzo, A;Kidd, MT;
Revista Brasileira de Ciência Avícola , 2004, DOI: 10.1590/S1516-635X2004000200004
Abstract: dietary lysine has been shown to impact the performance of broilers, particularly with aspect of breast meat accretion and yield. there have been studies that suggest that early dietary lysine has an effect on breast meat yield in male broilers. a study was designed to evaluate starter dietary lysine (1.20 vs 1.35% of diet as achieved by the addition of l-lysine at the expense of a filler) effect on performance of female broilers from three different genetic strain crosses, and monitor subsequent effects at 41 and 56 d of age. body weight and feed consumption were higher for birds consuming the high lysine starter diet, but feed conversions were similar when compared to the low lysine diet. body weight and feed conversion were similar among strains. mortality was unaffected by lysine level and strain cross. carcass and breast meat weight, but not yields, were higher in birds fed the high lysine diet. at 56 d differences in carcass yield, abdominal fat, and breast meat yield were seen among strains, such that the strain with highest yield had the least amount of abdominal fat in terms of absolute weight and percentage. no effect on processing yields by dietary lysine was observed at any time regardless of the growing characteristics of the broilers. however, for early slaughter ages, feeding high levels of dietary lysine during the starter phase could prove to be convenient when maximum live performance or breast meat absolute values are desiredin order to maintain the commercial quality of final products.
