Mushtaq Chalkoo, Mujahid Ahmad Mir, Hilal Makhdoomi
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.72015
Abstract: Objectives: To determine the feasibility and patient’s outcome of laparoscopic transabdominal preperitoneal mesh hernioplasty for inguinal hernias. Patients and Methods: This study was carried out from March 2011 to April 2014. A total of 130 patients underwent laparoscopic transabdominal preperitoneal mesh hernioplasty (TAPP) for uncomplicated inguinal hernia. Of this, 10 patients presenting with bilateral inguinal hernias were operated in the single sitting. A 15 cm × 12 cm polypropylene mesh was used in all cases. Operative morbidity, postoperative pain, seroma formation, evidence of superficial infection, chronic groin pain and hernia recurrence were noted. The majority of the patients were discharged within 24 hours and follow-up was done at 1 week, 1 month, and 6 months. Results: 130 patients presenting with uncomplicated inguinal hernias were operated over a period of three years in the department of surgery, Govt. Medical College Srinagar. The mean age of the patients was 39.18 years (range: 18 - 70 years). The median duration of operation was 48.5 minutes (range: 18 - 120 minutes). None of the procedure was converted to open inguinal hernia repair. Postoperative pain was observed in 9.23% of the cases and was easily controlled by oral analgesics. Six patients (4.62%) developed seroma, out of which one required aspiration while others settled conservatively. Two patients (1.54%) developed wound infection and one patient (0.77%) had recurrence. None of the patients developed scrotal hematoma or neuralgia. Return to normal activity after TAPP repair was found to be after a median of 16.1 days. Conclusion: Transabdominal preperitoneal repair for inguinal hernia using proline mesh may be a safe and effective procedure with low morbidity, early return to normal activity and with a very low recurrence after six months follow-up.

Mujahid Ahmad Mir, Farzana Manzoor, Balvinder Singh, Imtiyaz Ahmad Sofi, Abu Zaved Rameez, Sheikh Imran Farooq
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.710063
Abstract: Objectives: To identify independent risk factors for abdominal wound dehiscence and develop a risk model to recognize high risk patients. Methods: The samples studied were patients who underwent midline laparotomy in the department of surgery, SMHS Hospital Srinagar from March 2009 to April 2015. For each case of abdominal wound dehiscence, three controls were selected from a group of patients who had undergone open abdominal surgery as close as possible in time. Preoperative, perioperative, and postoperative variables and in-hospital mortality were studied for all patients. Cases were compared with controls using the chi-square test or the Mann-Whitney U-test for categorical or continuous data, respectively. Subsequently, multivariate stepwise logistic regression with backwards elimination test used to identify main independent risk factors of abdominal wound dehiscence. The resulting regression coefficients for the major risk factors were used as weights for these variables to calculate a risk score for abdominal wound dehiscence. Results: 140 cases of abdominal wound dehiscence were reported and compared with 420 selected controls. All variables that were significant in univariate analyses were entered in a multivariate stepwise logistic regression to determine which variables were significant independent risk factors. Major independent risk factors were male gender, chronic pulmonary disease, corticosteroid use, smoking, obesity, anemia, jaundice, ascites, and sepsis, type of surgery, postoperative coughing, and wound infection. Based on these findings, a risk model was developed. Conclusions: The model can give an estimate of the risk of abdominal wound dehiscence for individual patients. High-risk patients may be planned preventive wound closing with reinforcements as mesh.

PHYSICAL BEHAVIOUR OF FOAMED CONCRETE UNDER UNI-AXIAL COMPRESSIVE LOAD: CONFINED COMPRESSIVE TEST
Ahmad Mujahid Ahmad Zaidi
Modern Applied Science , 2010, DOI: 10.5539/mas.v4n2p126
Abstract: Foamed concrete now is a common material used in civil engineering work. There are increasing amount in research where foamed concrete are used primarily to resist compression force. In this research, physical behaviour of foamed concrete was investigated. Based on the past research, the compressive strength of foamed concrete typically proportioned to achieve only low compressive strength in unconfined condition. Standard compressive test were performed to obtain the compressive strength of foamed concrete. In this research, the confined condition is produced. Unconfined condition also was done, but here just focused on confined condition. The confined compressive test method consist of applying a compressive axial load to moulded cylinders at a rate which is within a prescribe range until failure occurs. The physical behaviour of foamed concrete under confined condition is the continuity of unconfined condition and will be the guidance to conduct the further research Keywords: foamed concrete, confined compressive test, mode of failure

Modern Applied Science , 2009, DOI: 10.5539/mas.v3n10p47
Abstract: Used of recycled aggregate (RA) in concrete can be described in environmental protection and economical terms. The application of recycled aggregate to use in construction activities have been practice by developed European countries and also of some Asian countries. This paper reports the results of an experimental study on the mechanical properties of recycled aggregate concrete (RAC) as compared to natural aggregate concrete (NAC). The effects of size of RA on compressive strength were discussed in this paper. The 100% of RA used in concrete mix to replace the natural coarse aggregate in concrete with 100 x 100 x 100 cube mm were cast with target compressive strength is 25 MPa. The 28-day compressive strength was crushed at 3, 14, 28 days are reported. It was found the size of 10mm and 14 mm of RA in RAC is quite similar performance with 10mm and 14mm size of natural aggregate (NA) in natural aggregate concrete (NAC). Keywords: Concrete, Recycled aggregate properties, performance of recycled aggregate concrete.
Application of Coordinate Resistance Functions on Predicting of Critical Impact Energy of Projectile for Perforation Phenomenon on Concrete Structure
Ahmad Mujahid Ahmad Zaidi
Journal of Mathematics Research , 2009, DOI: 10.5539/jmr.v1n2p13
Abstract: Great demand exist for more efficient design to protect personals and critical components against impact by kinetic missiles, generated both accidentally and deliberately, in various impact and blast scenarios in both civilian and military activities. In many cases, projectiles can be treated as rigid bodies when their damage and erosion are not severe. Due to the intricacy of the local impact damages, investigations are generally based on experimental data. Conclusions of the experimental observations are then used to guide engineering models. Local damages studies normally fall into three categories, i.e. empirical formulae based on data fitting, idealised analytical models based on physic laws and numerical simulations based on computational mechanics and material models. Perforation phenomenon is one of the local damage that has been investigated in the present study. It is describe as the complete passage of the projectile through the material with or without residual velocity is among the local damage threat in concrete structure. The relative of target thickness (H/d) to those critical energies are an important quantities that been explored in this study. The numerical simulation model has been developed using coordinate resistance function method for predict the perforation process. The target structures is described based on coordinate system in a mesh-less way, which impose penetration resistance on the projectile through resistance function based on dynamic cavity expansion theory. The penetration resistance on the surface of the rigid projectile is a function of the instantaneous velocity of that surface, which can be determined by the rigid body motion of the projectile. Standard finite element method is introduced to model the rigid body motion of the projectile and is coupled with the coordinate resistance in a mesh-less target by exchanging the velocities and stresses through user-interfaces. Predictions of the critical impact energies during perforation process are compared with semi-empirical model and corresponding experimental data. Encouraging predictions are observed when the model was validated with the existing experimental data.

Shabir Ahmad Mir, Sowriappan John Don Bosco
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.43038
Abstract:

The physical and functional properties of seven parboiled rice cultivars (Jehlum, K-332, Koshar, Pusa-3, SKAU-345, SKAU-382 and SR-1) were investigated at different soaking temperatures of 60, 70 and 80 and it was compared with the brown raw rice of the respective cultivars. Parboiling was observed to decrease L* value and increase a* and b* values. The hardness of rice was significantly increased after parboiling and varied among the cultivars with the highest in Jehlum. Parboiling resulted in the decrease of pasting parameters with the increase in soaking temperature from 60 to 80. The pasting characteristics of parboiled rice sample showed the typical behaviour having high initial viscosity, but lower peak viscosity in comparison to raw rice. The water absorption index and water solubility indices were subsequently increased with the increase in soaking temperature.

Mir Hashim Rasool, Mohammad Ayaz Ahmad, Shafiq Ahmad
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.71006
Abstract: In this paper an effort has been made to study the general characteristics of slow particles produced in the interactions of 32S-Em at 200 AGeV to extract the information about the mechanism of particle production. The results have been compared with the experimental results obtained by other workers. The multiplicity distributions of the slow target associated particles (black, grey and heavy tracks) produced by 32S-beam with different targets have been studied. Also several types of correlations among them have been investigated. The variation of the produced particles with projectile mass number and target size has been studied. Also the multiplicity distributions of slow particles with NBD fits are presented and scaling multiplicity distributions of slow particles produced have been studied in order to check the validity of KNO-scaling.

Pakistan Journal of Biological Sciences , 2004,
Abstract: Sixty-five bacterial strains were isolated from urine samples of patients suffering from urinary tract infection and identified by conventional methods. Eighty percent of total isolated organisms were found to be gram negative while remaining 20% were gram positive. Among gram negatives, E. coli and gram positive S. aureus and S. pyogene were the most prevalent organism. The percentage of gram negative isolates was as follows Escherichia coli (47.6%) followed by Pseudomonas aeruginosa (9.2%), Klebsiella pneumoniae (7.6%), Enterobacter aerogenes (6.1%), Proteus mirabilis and Serratia marcescens (4.6% each). The percentage of gram positive isolates includes, Staphylococcus aureus and Streptococcus pyogenes (4.6% each), Enterococcus faecalis, Staphylococcus epidermidis and Bacillus subtilis (3% each) and Staphylococcus saprophyticus (1.5%). The antibiotic resistance of identified organisms was carried out by disc-diffusion method with commercially available disc of fifteen antibiotics having different mode of actions such as cell wall synthesis inhibitors, membrane permeability alternatives, protein synthesis inhibitors and DNA synthesis inhibitors. Gram negatives showed more resistance to these antibiotics as compared to gram positive organisms. The most effective antibiotic for gram negative UTI isolates is gentamycin showing 69.2% efficacy, then sulfamethoxazole-trimethoprim (SXT-TMP) with 55% efficacy and then kanamycin having 50% efficacy. Among gram positives, chloramphenicol is most effective with 84.6% efficacy, then ofloxacin and gentamycin with 76.9% efficacy and then norfloxacin with 69.2% efficacy.
