The combination of ipsilateral humeral fractures at three different levels namely proximal, shaft and supracondyle has been rarely defined in the literature. We present a case report on such a complex injury in a 10-year- old child after falling down from the second floor of his house while playing. To the best of our knowledge, no such case report exists in the English literature. We define it as ＂double floating arm＂ injury. Firstly, shaft of humerus was open reduced and fixed with 4.5 mm narrow dynamic com- pression plate. Then closed reduction and pinning of the supracondylar humerus under an image intensifier was obtained. Open reduction using deltopectoral approach to the proximal humerus was done and the fracture was fixed with three k-wires. Ipsilateral multiple fractures in children often result from high energy trauma. Immediate reduction and fixation is required. Usually surgeons need to treat simple fractures firstly, which makes the subsequent treat- ment of complex fractures easier.

Most of the work on rice storage proteins focused on the major fraction - glutelin. In contrast to previous reports of the occurrence of single legumin-like polypeptide pair in glutelin, two-dimensional gel electrophoresis revealed many glutelin bands, with some having and some lacking disulphide-linkages. Five legumin-like polypeptide pairs exhibited wide heterogeneity over a range of molecular weight （Mr） 25 to 60 kDa, each having a large subunit （Mr ranged from 18 to 40.5 kDa） disulphide-bonded to a small subunit （Mr ranged from 16.5 to 18.0 kDa）. A band of 49 kDa was homodimeric with two subunits of 29 kDa each; a polypeptide of 51 kDa which altered position to ones corresponding to 53 kDa and 57 kDa on 2-D gels contained intrapolypeptide linkages. Polypeptides of 65 kDa and 60 kDa occurred as aggregates of 110 kDa. The number of polypeptides in other seed protein fractions albumins, globulins and prolamins, varied from four to ten. One of the albumin bands had intrapolypeptide disulphide linkages （20 kDa） and the globulins contained two such bands （13.5 and 20 kDa）. Thus, the present study provides a description of the polypeptide composition of different rice protein fractions that is finely resolved with respect to the occurrence of disulphide linkages.

The gamma quanta attenuation studies have been carried out to determine mass attenuation coefficients of 7041, 7075 and 7095 wrought aluminum alloys. The temperature dependence of linear attenuation coefficient, density and thermal expansion of these wrought aluminum alloys in the temperature range 300 k - 850 k have been reported. The measurements were done by using a gamma ray densitometer designed and fabricated in our laboratory. The data on variation of density and linear thermal expansion with temperature have been represented by linear equations. Volume thermal expansion coefficients have been reported.

The common practice of establishing rice in the rice-wheat system in India is manual transplanting of seedlings in the puddled soil. Besides being costly, cumbersome, and time consuming, puddling results in degradation of soil and the formation of a hard pan, which impedes root growth of subsequent upland crops. In addition, decreased availability and increasing cost of labor have increased the cost of rice cultivation through conventional methods. Because of these concerns, there is a need for mechanized transplanting of rice which is less labor-intensive and can ensure optimum plant population under nonpuddled and/or no-till conditions. A large number of on-farm trials were conducted at farmers’ fields in Haryana, India, from 2006 to 2010 to evaluate the performance of the mechanical transplanted rice (MTR) under nonpuddled and no-till situations as compared to conventional puddled transplant rice (CPTR). Compared with CPTR, nonpuddled MTR produced 3%-11% higher grain yield in different years. Rice cultivars, viz. HkR47, HkR127, PR113, PR114, PB1, PB1121, CSR30, and Arize6129, performed consistently better under nonpuddled MTR as compared to CPTR. Performance of different cultivars (PR113, PR114, HkR47, and Pusa 44) was also better under no-till MTR as compared to CPTR. The “basmati” cultivar CSR30 performed equally in no-till MTR and CPTR systems. The results of our study suggest that rice can be easily grown under nonpuddled and no-till conditions with yield advantages over the CPTR system. Even in the case of similar yield between CPTR and MTR systems, the MTR system will help in reducing labor requirement and ultimately, will increase overall profits to farmers.

The γ-ray densitometer has been designed and fabricated in our laboratory and carried out studies on temperature dependent γ-ray attenuation and thermo physical properties of NaCl, NaBr and NaF. The linear attenuation coefficients (μl) for the pellets of NaCl, NaBr and NaF as a function of temperature have been determined. The coefficients of temperature dependence of density have been reported. The variation of density and thermal expansion of NaCl, NaBr and NaF in the temperature range of 300 k - 1000 k have been studied and compared with results available in the literature. The temperature dependence of density and thermal expansion has been represented by linear equations. Volume thermal expansion coefficients have been reported.
