HIV/AIDS spread has opened a Pandora of medical and health problems apart from creating serious socio-psychological trauma for the victims and their families. Despite the governmental effort to curve the growing infection, very little success has been achieved. The northeastern region of India presents a very peculiar situation due to recurrent insurgency in all its states for long time and thus it became instrumental in paralyzing the social and health machineries to an extent, which still deteriorated the futile national effort to check.the deadly infection. The study tried to understand the level of awareness and correct k.owledge among the underprivileged scheduled tribes and scheduled castes women in the age group 15 -44 by exploring data from district level of Rapid Household Reproductive and Child Health Project Phase I (1998) and Phase II (1999) for Assam, Manipur and Nagaland and suggested a strategy to control the infection in the region. It is found that HIV/AIDS awareness was 59% among the women in all the three states with very few among them who had correct understanding of its prevention. A pronounced difference in the level of awareness was observed with respect to age, economy and residential status of the respondents.

Mesoporous carbon adsorbents from melamine–formaldehyde resin using nanocasting technique for CO_2 adsorption

引用

Journal of Environmental Sciences 2015年第6期27卷 238-248页

作者： Chitrak.hi Goel Haripada bhunia Pramod k. Bajpai Department of Chemical Engineering Thapar University

Mesoporous carbon adsorbents, having high nitrogen content, were synthesized via nanocasting technique with melamine-formaldehyde resin as precursor and mesoporous silica as template. A series of adsorbents were prepared by varying the carbonization temperature from 400 to 700°C. Adsorbents were characterized thoroughly by nitrogen sorption, X-ray diffraction（XRD）, scanning electron microscopy（SEM）, transmission electron microscopy（TEM）, thermogravimetric analysis（TGA）, elemental（CHN） analysis, Fourier transform infrared（FTIR） spectroscopy and Boehm titration. Carbonization temperature controlled the properties of the synthesized adsorbents ranging from surface area to their nitrogen content, which play major role in their application as adsorbents for CO2 *** nanostructure of these materials was confirmed by XRD and TEM. Their nitrogen content decreased with an increase in carbonization temperature while other properties lik. surface area, pore volume, thermal stability and surface basicity increased with the carbonization temperature. These materials were evaluated for CO2 adsorption by fixed-bed column adsorption experiments. Adsorbent synthesized at 700°C was found to have the highest surface area and surface basicity along with maximum CO2 adsorption capacity among the synthesized adsorbents. Break.hrough time and CO2 equilibrium adsorption capacity were investigated from the break.hrough curves and were found to decrease with increase in adsorption temperature. Adsorption process for carbon adsorbent-CO2 system was found to be reversible with stable adsorption capacity over four consecutive adsorption-desorption cycles. From three isotherm models used to analyze the equilibrium data, Temk.n isotherm model presented a nearly perfect fit implying the heterogeneous adsorbent surface.

Optoelectronics Letters 2010年第5期6卷 325-327页

作者： amal k.Ghosh Department of Applied Electronics & Instrumentation Engineering Netaji Subhash Engineering College Techno City Garia Kolkata 700152 India

The parity generators and the check.rs are the most important circuits in communication systems. With the development of multi-valued logic (MVL), the proposed system with parity generators and check.rs is the most required using the recently developed optoelectronic technology in the modified trinary number (MTN) system. This system also meets up the tremendous needs of speeds by exploiting the savart plates and spatial light modulators (SLM) in the optical tree architecture (OTA).

Trinary flip-flops using Savart plate and spatial light modulator for optical computation in multivalued logic

引用

Optoelectronics Letters 2008年第6期4卷 443-446页

作者： amal k.Ghosh Amitabha Basuray Department of Applied Electronics & Instrumentation Engineering Netaji Subhas Engineering College Department of Applied Optics & Photonics University of Calcutta

The memory devices in multi-valued logic are of most significance in modern research. This paper deals with the imple-mentation of basic memory devices in multi-valued logic using Savart plate and spatial light modulator (SLM) based optoelectronic circuits. Photons are used here as the carrier to speed up the operations. Optical tree architecture (OTA) has been also utilized in the optical interconnection network. We have exploited the advantages of Savart plates,SLMs and OTA and proposed the SLM based high speed Jk.D-type and T-type flip-flops in a trinary system.
