Collembolan Density and Diversity in a Forest and an Agroecosystem  [PDF]
D. Paul, A. Nongmaithem, L. K. Jha
Open Journal of Soil Science (OJSS) , 2011, DOI: 10.4236/ojss.2011.12008
Abstract: Collembola, commonly called “springtails” are wingless soft-bodied hexapods that are usually between 1 and 3 millimetres in length and occur in varying habits such as, soil surface and litter, under rocks or the bark of trees. The great majority develop in soil, feeding on fungi, bacteria, algae and decaying plant matter, and along with other soil fauna constitute the decomposer community. The present study examines the diversity, density, and seasonal variation patterns of collembolan fauna under different intensities of disturbance, as evidenced in a forest and an agroecosystem. Results indicate that both densities and diversity of collembola was higher in the forest than in the agroecosystem. Seasonal fluctuation exhibited an increase from spring to summer and autumn and a decrease during winter. The coorelation patterns with different chemo-edaphic factors did not show any specific trend.Indices of diversity and significant correlation values are discussed in light of landuse.
Biocontrol features in an indigenous bacterial strain isolated from agricultural soil of Gujarat, India
Parikh,K; Jha,A;
Journal of soil science and plant nutrition , 2012, DOI: 10.4067/S0718-95162012000200004
Abstract: the present investigation was carried out to test the biocontrol potential of a phosphate solubilizing bacterial strain, lk11 isolated from mungbean rhizosphere, in gujarat, india. this strain besides solubilizing the insoluble p also demonstrated inhibition of sclerotium rolfsii growth in agar plate and produced a volatile compound, hcn. during in vitro studies lk11 inhibited sclerotia germination by 40%. the most important contributing factor towards increased mungbean growth by reducing fungal attack was the enhanced production of antifungal compounds like pal (47 mm/ml/mg of tissue), phenolics (90.2 μg/ml/mg) and flavonoids (184.2 mg/ml/g) which is comparable to earlier reports available. testing the efficiency of this strain in consortium culture alongwith some other pgpr strains and biocontrol microbes at multilocational fields is in offing.

Indian Journal of Dermatology, Venereology and Leprology , 2003,
Abstract: 28 patients of hereditary punctate palmoplantar keratoderma (HPPK) were selected from DermatoVenereology out patients of Rajindra Hospital, Patiala. Cases were divided into group Awith PPK as majorfeature and group 6 with PPK as minorfeature. 11 /28 belonged to group A and 17/28 to group B. Group A patients revealed scattered pundate PPK in 6 and scattered pundate plus focal plaques in 5, while in group B patterns seen were KPPC (6), KPPC with focal (6), focal plus scattered punctate (3) and diffuse with superimposed KPPC (2).
Preparation and evaluation of sweet potato starch-blended sodium alginate microbeads
Jha Antesh,Bhattacharya A
Asian Journal of Pharmaceutics , 2009,
Abstract: The design of effective drug delivery systems has recently become an integral part of the development of new medicines. Hence, research continuously keeps searching for ways to deliver drugs over an extended period of time with a well- controlled release profile. The ionotropic gelation method was used to prepare sweet potato starch-blended controlled release alginate microbeads of ibuprofen. Sweet potato is an important crop in many developing countries. Although sweet potato originated from Central America, its ability to adapt to a wide variety of climatic conditions allows it to grow both in tropical and in moderate temperature regions of Africa, Asia and the Americas. The influence of various formulation factors such as in vitro drug release, entrapment efficiency, swelling study and micrometric properties was investigated. Other variables included sweet potato starch concentration, percentage drug loading, curing time, cross-linking agent and stirring speed during the microencapsulation process. The entrapment efficiencies were found in the range of 71.85 ± 2.04 - 94.53 ± 1.02%. The particle sizes were found in the range of 0.82 ± 0.006 - 1.08 ± 0.009 mm. This suggested that the ionotropic gelation method was successful in producing sweet potato starch-blended alginate microbeads.
Biocontrol features in an indigenous bacterial strain isolated from agricultural soil of Gujarat, India

Journal of Soil Science and Plant Nutrition , 2012,
Abstract: The present investigation was carried out to test the biocontrol potential of a phosphate solubilizing bacterial strain, LK11 isolated from mungbean rhizosphere, in Gujarat, India. This strain besides solubilizing the insoluble P also demonstrated inhibition of Sclerotium rolfsii growth in agar plate and produced a volatile compound, HCN. During in vitro studies LK11 inhibited sclerotia germination by 40%. The most important contributing factor towards increased mungbean growth by reducing fungal attack was the enhanced production of antifungal compounds like PAL (47 mM/ml/mg of tissue), phenolics (90.2 μg/ml/mg) and flavonoids (184.2 mg/ml/g) which is comparable to earlier reports available. Testing the efficiency of this strain in consortium culture alongwith some other PGPR strains and biocontrol microbes at multilocational fields is in offing.
Value of Bone marrow Examination in Pyrexia of unknown origin
A Jha,R Sarda
Journal of Pathology of Nepal , 2013, DOI: 10.3126/jpn.v3i6.8991
Abstract: Background: Pyrexia of unknown origin is a common diagnostic dilemma. Series of diagnostic modalities are required to arrive at diagnosis. Bone marrow examination is one of the common tests implicated in the diagnosis in combination with other diagnostic modalities. Present study has attempted to explore the causes of pyrexia of unknown origin based on bone marrow morphological study. Materials and Methods: In a one year prospective study conducted at Manipal Teaching Hospital, Pokhara, Nepal; bone marrow aspiration and biopsy was performed and evaluated morphologically, in 57 patients fulfilling the criteria of classic pyrexia of unknown origin. Results: In 42% cases; specific diagnosis could be made and hematological neoplasm was the most common finding followed by megaloblastic anemia, hypoplastic anemia and one case each of hemophagocytosis, malaria and tuberculosis. Acute leukemia was the most frequently encountered hematological malignancy followed by multiple myeloma, chronic myeloid leukemia, essential thrombocythemia and myelodysplastic syndrome. Conclusion: Morphological examination of bone marrow has important role in diagnosis of pyrexia of unknown origin. However, yield of diagnosis can be increased if it is combined with other diagnostic modalities including radiological, microbiological and serological tests.

WiMAX System Simulation and Performance Analysis under the Influence of Jamming  [PDF]
Rakesh Jha, Hardik Patel, Upena D. Dalal, Wankhede A. Vishal
Wireless Engineering and Technology (WET) , 2010, DOI: 10.4236/wet.2010.11004
Abstract: This paper presents simulation of WiMAX based system under jamming. The performance of the system was found out to greatly differ with the use of different jamming signals, allowing central areas to be identified, where system devel-opment should be focused on. In addition, from the basic theory point of view, rather surprising results were also found. This work should give a clear picture of how the studied WiMAX system performs under jamming as well as without jamming. The results show that some forms of interference degrade the performance of the system rapidly, thus the form of incoming jamming should be known and considered before deploying the system. Single carrier jamming and multi–carrier jamming are discussed here. The issues related to jamming and jamming reduction techniques are also covered. Jamming can destroy communication in the targeted area. Multi–carrier jamming is challenge in WiMAX because WiMAX is having OFDM based physical layer. Simulation is the main approach in this paper. OPNET MODELER 14.5 is the software used for the simulation purpose.
Evaluation of Preemergence Herbicides for Crop Safety and Weed Control in Safflower  [PDF]
Prashant Jha, Vipan Kumar, Charlemagne A. Lim, Ramawatar Yadav
American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.810158
Abstract: Weed management in safflower (Carthamus tinctorious L.) is a major challenge for growers due to very limited herbicide options available, particularly for broadleaf weed control. Field experiments were conducted at the Montana State University Southern Agricultural Research Center (MSU-SARC) near Huntley, MT in 2015 and 2016 to evaluate preemergence (PRE) soil-residual herbicides for crop safety and season-long broadleaf weed control in safflower. Among all herbicide programs tested, only sulfentrazone (105 g·ai·ha-1) alone or with pendimethalin (1064 g·ai·ha-1) caused 4% to 12% early-season visible injury to safflower, although the injury was not evident beyond 30
Health Care and Women's Empowerment: The role of Self Help Groups
S Chakravarty,A N Jha
Health, Culture and Society , 2012, DOI: 10.5195/hcs.2012.56
Abstract: Over the last couple of decades the concept of Self Help Groups (SHGs) and its potential as an effective tool to alleviate poverty and empower women has garnered considerable interest worldwide. Considering the importance given by policy makers across various nations to the group approach while conceptualizing, formulating and implementing any scheme or programme for the welfare of marginalized and underprivileged sections of the society (especially women), we identified the need to critically examine and explore the role of SHGs in the empowerment of women with a special emphasis on health status. To date, the functioning of SHGs has essentially been viewed only from an economic perspective. The existing approach puts encourages the economic development of women, with SHGs a mechanism to achieving this. However, how these economic benefits are being translated into the change in women’s status, particularly their health status, remains unexplored and ultimately unaddressed. This working research paper attempts to review the scope and limitations of SHGs in improving women’s health and empowerment based upon empirical work undertaken in the Jharkhand state of India. Our paper also explores the extent to which SHGs can be involved in attaining better health status for women, and thereby point the way for further research.
