Abstract

The zinc copper ferrite nanoparticles were synthesized via hydrothermal method. Further, the X-ray diffraction patterns confirmed the formation of cubic spinel structure. The microstructure was analyzed using the FESEM and TEM study. The results revealed that the symmetrical and asymmetrical nanospheres were found in the surface morphology. The dielectric studies indicated that the behavior of dielectric constant and dielectric loss as a function of frequency and composition. In addition, the Maxwell-Wagner interfacial polarization was observed. Similarly, the ac-electrical conductivity behavior was well understood. The M-H loops indicated the ferromagnetic behavior of ZnCu ferrite samples. [ABSTRACT FROM AUTHOR]

38. Effect of water dipping on separation techniques of pomegranate (Punica granatum L.) arils

Author

Hota, Monalisa, Dahiya, D. S., Hota, Monalisa, and Dahiya, D. S.

Abstract

For easy separation of arils, pomegranate fruits were subjected to hot water dipping and normal water dipping treatments. Minimum time of separation as 4.10 min/kg of fruit was observed in case of hot water (80±2°C) dip for 2 min which was at par with hot water (80±2°C) dip for 1 min as 4.7 min/kg. All treatments saved time over the traditional method but only hot water dipping was significant without any significant adverse effect on aril quality in comparison with traditional method except anthocyanin and phenols. Anthocyanin content reduced and phenols content increased in comparison to traditional method.

Abstract

A long-term field experiment started in 1995 on Research Farm of Department of Soil Science, CCS Haryana Agricultural University Hisar (India) was selected to study the effects of organic manures and chemical fertilizers on productivity, seed quality and nutrient use efficiency of wheat under pearl millet-wheat cropping system. The organic manures (15 Mg FYM, 5 Mg poultry manure and 7.5 Mg pressmud) were applied alone and in combination with fertilizers (150 kg N + 30 kg P2O5 ha-1) and compared with chemical fertilizers applied alone (150 kg N + 60 kg kg P2O5 ha-1 and 75 kg N + 30 kg P2O5 ha-1). The results showed that the application of organic manures in combination with N and P fertilizers significantly increased all yield attributes, i.e. plant height, number of tillers/m row length, spike length, number of grains/spike. Higher grain yield of wheat (61.4, 57.4 and 62.7 q ha-1) was observed when recommended dose of N and half of P was applied in conjunction with FYM, poultry manure and pressmud, respectively. Grain yield of wheat increased by 13.5, 6.1 and 15.9%, respectively, under same treatments when compared with recommended dose of N and P fertilizers. Among the organic manures, highest yield (32.9 q ha-1) was obtained with pressmud application. However, application of organic manures alone resulted in poor yield and even lower than 50% recommended dose of N and P fertilizer. All the seed quality parameters (standard germination, shoot length, root length, seedling dry weight, seedling vigour index-I and -II) improved with the combined application of organic manures and chemical fertilizers as compared to their individual application. The partial factor productivity of N and P increased with combined application organic manures and chemical fertilizer as compared to chemical fertilizers applied alone, however, nutrient harvest index and their utilization efficiency decreased with combined application of organic manures and fertilizers as compared to their individual application.

Abstract

Massive rectal bleeding is an uncommon presentation of ileal tuberculosis (TB). We report an uncommon cause of anemia in a post-renal transplant patient due to massive lower gastrointestinal (LGI) bleed. The index case had a normal upper and LGI endoscopy, but the 99technetium labeled red blood cell scan showed active bleeding from terminal ileum and caecum. Microscopic examination of the resected specimen revealed tubercular granuloma with acid-fast bacilli. Intestinal TB should be a differential diagnosis for massive LGI bleed in immunosuppressed patients in developing country. [ABSTRACT FROM AUTHOR]
