ضربِ کلیم

بال جبریل کی اشاعت کے چند ماہ بعد جولائی 1936ء میں ضرب کلیم منظر عام پر آئی۔ اقبال کا یہ اردو کا تیسرا مجموعہ کلام ہے” ضرب کلیم “ فکر کی پختہ اور مستحکم صورت کا مجموعہ ہے۔اقبال نے اس کتاب کے ہر حصے کو عنوانات میں تقسیم کیا ہے۔ عنوانات درج ذیل ہیں ۔ (1) اسلام اور مسلمان (ii) تعلیم و تربیت (iii) عورت (iv) ادبیات ، فنون لطیفہ (۷) سیاسیات مشرق و مغرب (vi) محراب گل افغان کے افکار۔ ہر عنوان میں بہت سی نظمیں ضمنی موضوعات کے تحت دی گئی ہیں۔ محراب گل افغان کے اذکار میں نمبر شمار دے کر بیس افکار پیش کیے گئے ہیں۔

Analysis of Stair Climbing to Find an Optimum Knee Angle in Order to Reduce the Chances of Leg Muscle Fatigue and Injuries

Stair climbing is one of the unique exercises which is frequently used and helps in maintaining the leg muscles active and healthy. However, if the height of the stair is not optimum, it may cause serious injuries due to increased or decreased knee angle that may damage the human leg muscles such as quadriceps and hamstring involved in its proper function. A stair climbing leg model PASCO ME-7001 was designed to find an optimum knee angle for reducing the maximum chances of leg muscle fatigue and injuries by using the force sensors. Resultant forces applied on leg muscles i.e. hamstring and quadriceps at 4 different average angles: 40º, 57º, 68º, and 76º for four different stair heights: 3", 5", 7", and 9" respectively were studied graphically during ascending stairs. Also, the energy consumption of quadriceps is calculated for the desired 4 average angles. The optimum knee angle maybe 57-68 degrees at 5"-7" stair height for both flexion and extension of the leg during stair climbing.

Relative Efficacy of Plant Growth-Promoting Rhizobacteria Possessing Phosphate Solubilizing And/Or Acc-Deaminase Activity for Improving Growth and Yield of Cereals

The phosphorus content in soil (organic plus inorganic) is usually much higher than plant requirements, however bioavailability of phosphorus to plant is one of the major plant growth limiting constraints. Even the added P as phosphatic fertilizer may get unavailable because of its fixation/ precipitation in soil, particularly in calcareous and alkaline soils. Thus, there is dire need to mobilize this big pool of soil phosphorus for improving crop yields on sustainable basis and one of the strategies useful for this purpose is the use of specific microorganisms applied as inocula. Some plant growth promoting rhizobacteria (PGPR) are known to promote plant growth by solubilizing this unavailable/insoluble phosphorus (P) in soil while others enhance P acquisition by plant indirectly through promoting extensive root growth because of their 1- aminocyclopropane-1-carboxylate (ACC)-deaminase activity. As far as we know, for the first time we compared the PGPR carrying dual traits (phosphorus solubilizing and ACC deaminase activity) vs. single trait PGPR for their effectiveness to improve P nutrition and growth of wheat and maize. To achieve these objectives, a series of experiments was conducted to document the impact of selected PGPR on wheat and maize under axenic and natural conditions. A total of thirty five (35) isolates were collected from the rhizosphere of wheat and maize by using enrichment techniques. Six isolates were selected on the basis of their P-solubilizing and/or ACC deaminase activity. Among the selected six rhizobacteria, two (K1 & K2) predominantly carry ACC-deaminase activity, the other two (K3 & K4) had P-solubilization activity while rest of the two (K5 & K6) carried both of these traits. The seeds of wheat (Bhakar 2002) and maize (Sahiwal 2002) were inoculated with these six selected isolates and sown under axenic conditions in growth medium containing rock phosphate (RP) as P source. The same six strains of PGPR were tested under pot and field conditions with the objectives to improve P use efficiency in inoculated wheat and maize crop under five fertilizer treatment matrix including F0 (NK fertilizer only); F1, (F0+rock phosphate (RP); F2, (F0+DAP); F3, (F0+compost) and F4, (F0+RP-enriched compost). Inoculation with all the PGPR strains promoted growth and yield parameters of wheat and maize compared to respective uninoculated control under all the five fertilizer treatments, however, effectiveness of PGPR strains varied in different fertilizer treatments. Results also clearly revealed that dual trait PGPR strains were most promising and consistent in increasing growth and yield parameters of wheat and maize compared to single trait strains under all fertilizer treatments. Comparison of single trait PGPR indicated that P solubilizers were relatively more effective than those PGPR containing ACC deaminase activity implying that the improvement in P-nutrition is more critical for improving plant growth than just improving root growth with respect to P nutrition as well as growth and yield of wheat and maize. These results may imply that PGPR possessing dual traits could be the best candidates for formulation of the most effective and consistent biofertilizer. Overall, fertilizer treatments also differed from each other with respect to affecting growth and yield parameters of wheat and maize as fertilizer treatment F2, (F0+DAP) proved the best while F0, (N and K only) had the minimum impact.
