Mohammad Kalimuddin Ahmad, Stephan Didas, Alemdar Hasanov, Javid Iqbal
Journal of Signal and Information Processing (JSIP) , 2015, DOI: 10.4236/jsip.2015.62017
Abstract: Ahmad et al. in their paper [1] for the first time proposed to apply sharp function for classification of images. In continuation of their work, in this paper we investigate the use of sharp function as an edge detector through well known diffusion models. Further, we discuss the formulation of weak solution of nonlinear diffusion equation and prove uniqueness of weak solution of nonlinear problem. The anisotropic generalization of sharp operator based diffusion has also been implemented and tested on various types of images.

Javid Ahmad Banday, Feroz Ahmad Mir, Saleem Farooq, Mushtaq Ahmad Qurishi, Surinder Koul, Tej Kishen Razdan
American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.33029
Abstract: Oxypeucedanin hydrate monoacetate (Mol. Formula = C18H18O7) micro-crystals were obtained by acetylation of oxy-peucedanin hydrate, a furanocoumarin, isolated from the roots of Prangos pabularia. The composition related structural, thermal and optical properties were investigated. All the crystals were found to have triclinic structure. From thermal studies of these crystals, stability, melting point and other relevant informations were obtained. Their blue emission, less absorption in entire visible range and band gap predicts these crystals as good candidate for modern optoelectronic devices.

Sajad Ahmad Ganai, Hamida-Tun-Nisa Chishti, Javid Ahmad, Siraj Ahmad
American Journal of Analytical Chemistry (AJAC) , 2012, DOI: 10.4236/ajac.2012.33036
Abstract: A composite ion exchange material, polyaniline stannic silicate was prepared under different experimental conditions. Ion exchange material synthesized at pH 1.0 shows an ion exchange capacity 1.6 meq/g for Na+ ions. The exchanger has been characterized on the basis of X-ray and TGA. Ion exchange capacity, pH titration, elution and distribution studies were also carried out to determine the preliminary ion exchange properties of the material. The effect of temperature on the ion exchange capacity of the material at different temperatures has been studied. The sorption behavior of metal ions was also explored in different surfactant mediums. The practical utility of the material was explored by achieving quantitative separation of toxic metal ions in synthetic mixtures.

Polyaniline stannic molybdate—an organic-inorganic composite material, was prepared via sol-gel mixing of organic polymer polyaniline into matrices of inorganic precipitate of stannicmolybdate. The composite material synthesized at pH 1.2 showed an ion exchange capacity 1.8 meq/g for Na+ ions. Ion exchange capacity, pH titration and distribution studies were carried out to determine the preliminary ion exchange properties of the material. The distribution studies showed the selectivity of Hg(II) ions by this material. The effect of temperature on the ion exchange capacity of the material at different temperatures had been studied. The sorption behavior of metal ions was also explored in different surfactant media.

Background: Gallstones are generally uncommon in infants and children. Formation of gallstone is a very poorly understood phenomenon. In general, the risk factors for cholithiasis in infants include patients who are ill, are receiving hyperalimentation, are premature, have congenital anomalies and have necrotizing enterocolitis. Children aged 1 - 5 years most frequently have hemolysis as the underlying condition [1]. Materials and Methods: From Jan 2012 to Feb 2014, a study entitled “A Prospective Study of Cholelithiasis in Children” was conducted in Postgraduate Department of General Surgery Govt. Medical College Srinagar. The patients selected for the study were in the age group of 1 to 14 years of either sex. There were a total of 141 cases, out of which only 38 had ultrasound documented gallstones. All the patients included in the study were evaluated for prevalence, clinical presentation, and pathological features of gallstones, and were analysed for metabolic causes of gallstones. Results: The prevalence of chliothiasis in symptomatic patients was found to be 26.95% higher than the prevalence of gallstones in children in other parts of world, also the mean age of presentation was 9.3 years ranging from 6 - 14 years. Male to female ratio was 3:2 and male predominance was found in all age groups contrary to female predominance in adults. Most common presenting symptom was right upper quadrant pain followed by vomiting and nausea similar to presentation of symptomatic gallstones in adults. 4 patients had a positive family history of cholithiasis in the first degree relatives; 25 (65.7%) patients had no underlying risk factor for gallstones contrary to presumption that gallstones in children are mostly secondary to some hematological disorder or other predisposing factors. Chronic cholecystities was found in 81% of patients with gallstones and composition of gallstones retrieved was different from those of adult gallstones with calcium carbonate gallstones relatively common in children but composition of black and brown stones was almost similar to adult stones. Conclusion: Gallstone disease was increasingly gaining recognition in peadiatic practice due to significant documented increase in non-heamolytic cases

Fakhrossadat Mortazavi,Ahmad Jafari-Javid
Iranian Journal of Pediatrics , 2009,
Abstract: Background:Copper sulfate is a blue and odorless salt with various industrial, chemical, agricultural and medicinal applications. Copper sulfate poisoning is rare in children. Case Presentation:A 23-month old boy accidentally ingested a solution of copper sulfate, used as a disinfectant agent in animal husbandry. He was referred to Childrens Hospital of Tabriz because of frequent vomiting and lethargy. The major systemic complications were intravascular hemolysis, anemia and acute renal failure. The patient was successfully treated with multiple packed cell transfusions, dimercaprol, penicillamine and peritoneal dialysis. Plasma copper level 15 days after ingestion was 216 μg/dl. Conclusion:Copper sulfate is a highly toxic agent that, when ingested, can cause local and systemic damage including coma, shock, severe intravascular hemolysis, hepatotoxicity and acute renal failure with high mortality.
Effect of Plant Growth Regulators on Leaf Number, Leaf Area and Leaf Dry Matter in Grape
Zahoor Ahmad BHAT,Rizwan RASHID,Javid Ahmad BHAT
Notulae Scientia Biologicae , 2011,
Abstract: Influence of phenylureas (CPPU) and brassinosteriod (BR) along with GA (gibberellic acid) were studied on seedless grape vegetative characteristics like leaf number, leaf area and leaf dry matter. Growth regulators were sprayed on the vines either once (7 days after fruit set or 15 days after fruit set) or twice (7+15 days after fruit set). CPPU 2 ppm+BR 0.4 ppm+GA 25 ppm produced maximum number of leaves (18.78) while as untreated vines produced least leaf number (16.22) per shoot. Maximum leaf area (129.70 cm2) and dry matter content (26.51%) was obtained with higher CPPU (3 ppm) and BR (0.4 ppm) combination along with GA 25 ppm. Plant growth regulators whether naturally derived or synthetic are used to improve the productivity and quality of grapes. The relatively high value of grapes justifies more expensive inputs. A relatively small improvement in yield or fruit quality can justify the field application of a very costly product. Application of new generation growth regulators like brassinosteroids and phenylureas like CPPU have been reported to increase the leaf number as well as leaf area and dry matter thereby indirectly influencing the fruit yield and quality in grapes.

Introduction: Incisional hernias frequently complicate abdominal surgeries with a varied incidence as reported to be 2% - 20%. The risk factors of development of incisional hernias include immunocompromised state, diabetes mellitus, smoking, obesity, wound infection at the index surgery, emergency surgery. Materials and Methods: The study design was prospective and included 62 patients with incisional hernias. The patients were evaluated preoperatively on OPD basis with history, clinical examination, baseline investigation, ultrasound abdomen and computed tomogram. Results: The mean age was 48.9 years with male:female ratio of 1:1.4. Mean BMI was 30.1 kg/m2. Out of 62 patients in the study 61.2% had concomitant hypertension and were on treatment for the same. 30.6% were clinically hypothyroid, 38.7% were diabetic and 54.8% were smokers. There were multiple factors present in patients in the current study which were observed to be possible to have risked the patients to incisional hernias after an abdominal surgery. 21 patients had defect size ranging from 5 to 10 cm and 41 patients were bearing a hernia of the defect size of 10 cm or more. The mean operative time was 221.7 minutes. Conclusion: Incisional hernias are a part of surgical practice that would probably glue to it to the end of time. A progression from primitive suture repair with recurrence rates of over 65% to modern day mesh reinforced repairs with recurrences aimed at 0% is always welcome. But still then the placement of mesh in different positions or layers of abdominal wall yields different results.
Pakistan Veterinary Journal , 2006,
Abstract: This trial was conducted for a period of 90 days at the Livestock Experiment Station, Bahadurnagar, Okara, Pakistan during September - November, 2002. Eighteen lactating buffaloes were divided into three groups A, B and C, with six animals in each group. Animals of Group A were fed a concentrate ration with 2 ml of Biovet per kg of feed, while those of Group B were fed an experimental ration having probiotic 500 gms in 100 kg of concentrate mixture. The Group C animals served as control group. The average daily milk yield was 7.60, 7.39 and 6.15 litres in groups A, B and C, respectively. The corresponding values for milk fat were 7.60, 7.39 and 6.15 percent. The daily feed intakes for concentrate mixture were 4.36, 4.38 and 4.41 kg, while fodder intakes were 35.28, 35.29 and 37.46 kg in respective groups. The values for feed efficiency per kg were 1.70, 1.75 and 2.14 on dry matter basis, 0.197, 0.203 and 0.251 on crude protein basis, while 1.05, 1.08 and 1.35 on TDN basis in Groups A, B and C, respectively. It was also observed that under same feeding and management conditions, the lactating buffaloes supplemented with Biovet (Group A) produced more milk @ 1.45 litres per day, while Group B buffaloes supplemented with probiotic produced 1.22 litres more milk per day than Group C. There was a significant (P<0.05) difference in milk yield between groups A and C, and B and C, while these differences were not significant for average daily feed intake and feed efficiency on crude protein basis. The Biovet (BM-Technology) has favourable effect on milk yield and feed efficiency due to beneficial micro-organisms (BM) and combined function for increased digestibility of concentrate mixture and fodder in lactating buffaloes.
