Abstract: Introduction: Tendon Achilles is largest tendon of the body and is made of fibrous tissue, descends from calf & gets attached to calcaneum. The injuries of this strongest tendon are not only uncommon but disabling as well. Twenty one tendons in 20 patients were managed successfully using Bosworth repair in the department of Orthopaedics NMC Hospital NawabShah during the period from March 2002 to April 2006.
Patients & Method: All patients were male and age ranged from 25 years to 55. Thirteen injuries were caused due to direct trauma, 3 patients noticed sudden jerk during high jump while playing, 3 had fall while running on plain ground and use of prolong corticosteroids caused 2 bilateral tendon injuries in one patient (Figure 1). Eleven patients sustained right side injury while 9 had their left side tendon injury. All patients were admitted through OPD & Emergency departments and were operated after their pre-op work & anesthetist’s fitness was completed. Period lapsed from injury to admission was one day to 3 months and surgery was performed within 1day to 6 days after their admissions (Figure 3).
Results: All twenty patients healed completely. Out of these 20 patients 17 were farmers, one medical professional and two were agriculture mechanics (Figure 4). Follow-up period in all these patients was over 15 months and no patient lost to follow- ups.
Conclusion: Public awareness service programs and interaction between Orthopaedic consultants and other health professionals including general practitioners of the areas can prevent not only delay in diagnosing such problems, but shall minimize the ailment suffered by these patients. Nevertheless, all injuries of tendon Achilles should be dealt immediately to restore the full function of this strongest tendon of body regardless the lapse of any length of time.

Abstract: Many insects are known to give response in adaptive way for seasonal changes in day lengths. Photoperiod control’s many developmental responses and allows insects to survive periods of unfavorable environmental conditions. An experiment was conducted to study the effect of different photoperiod lengths on biological parameters of green lacewing, Chrysoperla carnea. Four different photoperiod regimes were selected with varying lengths of light/dark hours (8/16, 10/14, 24/0 and 0/24) at a constant 26±2°C temperature with 70 % RH (relative humidity) in the laboratory. Photoperiod regimes affected the development of C. carnea from egg to adult. In complete darkness (L: 0 D: 24), minimum egg laying, hatching, larval survival and adult emergence were recorded. Incubation period for eggs, larval period and pupal duration were also significantly longer in complete darkness as compared to other treatments 8L: 16D and 10L: 14D. Whereas, the treatment with complete light hours (L: 24, D: 0) resulted in maximum egg laying hatching, larval survival and adult emergence. The incubation period for eggs, larval and pupal duration significantly shortened as compared to other treatments.Sex ratios skewed towards female when full light hours were provided for development.
Keywords: Chrysoperla carnea, photoperiod regimes, hatching, larval survival, sex ratios.

Abstract: The effect of micronutrients on damage compensation and yield components of okra was investigated, using three foliar sprays (at 15 days interval) of Effective microorganisms (EM-1), Wokozim and Kissan Supreme Tonic (KST). Weekly observations on sucking complex (thrips, jassid, whitefly) and pod borers were carried out. The yield ha-1 of green pods was recorded to ascertain the compensation of the damage done by the insect pests. The damage done by sucking complex and borers was markedly compensated by the micronutrients, and okra pod yield in EM-1, Wokozim and KST sprayed plots were 10911, 9507 and 8948 kg ha-1, respectively as compared to 8034 kg ha-1 in control. The effect of micronutrients on crop growth and subsequently on sucking complex infestation was significant and thrips, jassid, whitefly and borer infestation was relatively lesser in plots sprayed with micronutrient as compared to the control. KST was most effective in damage compensation of sucking complex and borers with highest okra green pod yield (P<0.01), followed by Wokozim and EM-1 when compared with control.
Keywords: Okra, micronutrients, sucking complex, okra yield.

Abstract: Power generation from natural wind is the crucial issue due to rapid depletion of non-renewable energy resources and their pollution demerits. Most observers agreed that long-term economic growth will require technical innovation to make wind energy more competitive with other forms of energy. One among the key trends is the push to improve productivity. Vertical axis wind turbines are capable of extracting power from wind regardless of direction of natural wind flow. Very less work is devoted to improve the characteristics of wind to make it more useable for power generation. Major portion of the research is related to the wind energy system design that caters the domestic needs. A micro vertical axis wind turbine system with integrated wind accelerating techniques is proposed. At the outer of the turbine a wind accelerating convergent duct with larger wind area is proposed, that will perform as a nozzle action to accelerate the natural wind when it strikes on the front half portion of the turbine blades. Proposed micro wind turbine is also integrated with satellite dish type parabolic structure, mounted at the top of the turbine. The parabolic concentrator surface is coated with sun rays reflecting mirrors, sunlight striking on paraboliod surface is directed to words a heat absorbing hollow cylinder, erected at the center of the paraboliod concentrator. Hollow cylinder is the path channel for air leaving the turbine. Air molecules passing through this channel will be heated up, moving rapidly up word creating momentum in air leaving from the turbine. Design of the proposed vertical axis wind turbine system integrated with wind accelerating techniques and experimental study of wind accelerating duct composed of various section is reported in this research work.
