Background: The experience of short term results of laparoscopic inguinal hernia repair using 3D mesh in a developing country is reviewed. Methods: From January 2012 to February 2014, 53 patients underwent laparoscopic inguinal hernioplasty. A retrospective case series of 53 consecutive patients undergoing TEP/TAPP by a single surgical team was followed prospectively with a focused physical examination and interview. 4 out of 53 patients had recurrent hernia following open repairs and 49 had primary hernias. Data collected included operative time, intraoperative bleeding, intraoperative difficulties, immediate postoperative pain, chronic groin pain, recurrence, sensory disturbance, activity or occupational limitation and personal satisfaction. Results: All the patients were male aged 32 to 75 years with a mean age of 53.5 years. Mean operative time was 37.4 minutes; intraoperative dissection, blood loss were less; and immediate postoperative pain was negligible as assessed by VAS. There was no mortality or major morbidity. Mean follow-up was 12 months (2 to 18 months). Follow-up was completed by interview and physical examination. Hernia was not found to recur during the follow up period. Chronic pain occurred in 2 patients (3.7%), which was mild in nature. Ninety-seven percent of patients were satisfied with their repair and would or had recommended TEP/TAPP to others using 3D Mesh. Conclusions: Short-term results of TEP/TAPP hernia repair using 3D mesh demonstrated to be an effective and safe procedure with low prevalence of chronic pain that is generally of a mild, infrequent nature. It was also concurred that there is decrease in operative time. Manipulation of mesh was significantly reduced. Intraoperative bleeding and use of post operative analgesia was reduced considerably. There was no recurrence, however the cost of the mesh increased the overall cost of the procedure acting as a limiting factor in a developing country.

Strategies in Trauma and Limb Reconstruction , 2008, DOI: 10.1007/s11751-008-0036-x
Abstract: The management of perilunate dislocations diagnosed later than three months continue to elicit debate with literature being scarce. We report a 22-year-old male with transscaphoid perilunate dislocation who reported to our hospital 8 months after sustaining the injury. Open reduction was done along with bone grafting. Five years after the surgery the patient is symptom-free with an excellent range of motion.
A Study of Transverse Momentum Distributions of Hadrons at LHC
Saeed Uddin,Inam-ul Bashir,Riyaz Ahmed Bhat,M. Farooq Mir
Physics , 2014,
Abstract: The transverse momentum distributions of various hadrons produced in most central Pb+Pb collisions at LHC energy Root(s_NN) = 2.76 TeV have been studied using our earlier proposed unified statistical thermal freeze-out model. The calculated results are found to be in good agreement with the experimental data measured by the ALICE experiment. The model calculation fits provide the thermal freeze-out conditions in terms of the temperature and collective flow effect parameters for different particle species. Interestingly the model parameter fits reveal a strong collective flow in the system which appears to be a consequence of the increasing particle density at LHC. The model used incorporates a longitudinal as well as transverse hydrodynamic flow. The chemical potential has been assumed to be nearly equal to zero for the bulk of the matter owing to a high degree of nuclear transparency effect at such energies. The contributions from heavier decay resonances are also taken into account in our calculations.

Abstract: The infection control in surfaces of public toilets environment is a matter of great concern and a major challenge, especially during mass gatherings. The present study aimed to evaluate the antimicrobial efficacy of titanium dioxide nanoparticles coating on environmental surfaces of public toilets during Hajj time. A pilot study has been designed to evaluate the antimicrobial efficacy of titanium dioxide nanoparticles on the surfaces of public toilets. The results showed a significant reduction in colony-count of the test samples. Maximum average reduction count of test microbes of the seats and walls reached (99.7%) while that of the doors reached (99.1%) which was statistically significant (P value = 0.001). It was concluded that there was a marked effect of a mixed TiO2 coating on reducing the microbial count at the surfaces of public toilets environments. Further research on efficacy against specific organisms, intestinal parasites, fungi, viruses and bacteriophage is recommended.
The dynamic condylar screw in the management of subtrochanteric fractures: does judicious use of biological fixation enhance overall results?

Strategies in Trauma and Limb Reconstruction , 2007, DOI: 10.1007/s11751-007-0022-8
Abstract: Subtrochanteric fractures are fraught with certain anatomic, biologic and biomechanical challenges. Evolution of implants like the Gamma nail, fixed-angle nail plates, compression hip screws and dynamic hip screws with trochanteric stabilization plates underlines a persistent quest for a better implant. We studied the dynamic condylar screw DCS as an implant on a series of 30 consecutive patients with subtrochanteric fractures. Our purpose was to assess this implant as a panacea for subtrochanteric fractures. All cases of AO type A and B were anatomically fixed, whereas type C was biologically plated. The idea was to assess the applicability and adaptability of the DCS. Fractures in 29 cases united, with one patient suffering from an implant failure. There were 17 excellent, 5 good, 5 fair and 3 poor results. The DCS is a definite advance over previous methods of treatment; when combined with the utilization of biological fixation techniques for comminuted fractures, can be relied upon to treat all types of subtrochanteric fractures.

Abstract: Calorie restriction (CR) is as close to a real fountain of youth as any known technique is. Caloric restriction known to extend the human lifespan by up to five years has quietly become accepted among leading researchers. Even scientists who are cautious about anti-aging hype say it works. The formula is simple: Eat less. It could add years to your life. In the context of health and longevity, I analyzed data documenting proofs which suggest that the caloric restriction extends life span and retards age-related chronic diseases in a variety of species, including rats, mice, fish, flies, worms, and yeast as well as improve biomarkers of aging in humans. Research has shown that not only does it result in a longer lifespan, but it also lowers blood pressure, oxidative damage, cardiovascular disease, modifies insulin sensitivity, reduces loss of central nervous system cells, strengthens the immune system, lowers cholesterol, diminishes the rate of heart disease, reduces muscle oxygen loss, improves muscle function, reduces free radical damage to body tissue and helps stabilize blood sugar in adult-onset diabetes. Caloric restriction the most widely recognized life span-extending intervention has shown that it does indeed have age-slowing effects in humans like it has been shown to work in animals and Dr. Fontana has already made medical history in studying anti aging effects of caloric restriction.

Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.32022
Abstract: This paper proposes the design and development of a novel, portable and low-cost intelligent electronic device (IED) for real-time monitoring of high frequency phenomena in CENELEC PLC band. A high speed floating-point digital signal processor (DSP) along with 4 MSPS analog-to-digital converter (ADC) is used to develop the intelligent electronic device. An optimized algorithm to process the analog signal in real-time and to extract the meaningful result using signal processing techniques has been implemented on the device. A laboratory environment has setup with all the necessary equipment including the development of the load model to evaluate the performance of the IED. Smart meter and concentrator is also connected to the low voltage (LV) network to monitor the PLC communication using the IED. The device has been tested in the laboratory and it has produced very promising results for time domain as well as frequency domain analysis. Those results imply that the IED is fully capable of monitoring high frequency disturbances in CENELEC PLC band.
Voltage Mode Universal Filter Using Current Differencing Buffered Amplifier as an Active Device  [PDF]
Sheikh Ajaz Bashir, Nisar Ahmed Shah
Circuits and Systems (CS) , 2012, DOI: 10.4236/cs.2012.33038
Abstract: Integrated filter circuit design resulted in desire for replacement of Inductors by active elements like Operational Amplifiers which led to the introduction of active filters. Active filter design has evolved over a period of time. Starting with OP AMPs, we have witnessed phenomenal growth of active component usage in filter design and development catering to varying requirements. This has contributed greatly in emergence of circuits with minimal limitations and advantages in terms of wide Bandwidth and High slew rates. Current Differencing Buffered Amplifier (CDBA) based active filter design has resulted in introduction of many novel circuits .This paper proposes a new Voltage-mode three input and Single output (TISO) multifunction filter based on single CDBA, four resistors and two capacitors. This second order filter circuit is capable of realizing various filter functions by choosing values of the three inputs variably. The natural frequency (ω0) can be tuned with passive components and the Q of the circuit is independent of (ω0) .The higher cascading capability of the circuit is ensured because of its low - output impedance. Further PSPICE-simulated results are in conformity with theoretical values.

Ahmed Ibrahim, Yeong Ryu, Mir Saidpour
Modern Mechanical Engineering (MME) , 2015, DOI: 10.4236/mme.2015.51001
Abstract: This paper discusses the stresses developed in a thin-walled pressure vessels. Pressure vessels (cylindrical or spherical) are designed to hold gases or liquids at a pressure substantially higher than the ambient pressure. Equations of static equilibrium along with the free body diagrams will be used to determine the normal stresses \"\" in the circumferential or hoop direction and\"\" in the longitudinal or axial direction. A case study of internal pressure developed in a soda can was determined by measuring the elastic strains of the surface of the soda can through strain gages attached to the can and connected to Strain indicator Vishay model 3800.
