It is imperative to know the reproductive parameters of the existing swine breed for profitable farming in Bangladesh. This study was designed to determine the reproductive parameters of sows at hilly areas. A total of 245 pigs with47 breedable sows were included. The data on age at puberty, oestrous cycle length, oestrus duration, gestation length,interval between furrowing and onset of oestrus, first service pregnancy rate, service per pregnancy and number ofpiglets born per sow in local and cross bred sows were determined. The present study revealed that age at pubertyof local and cross breed sows was 232.5 ± 8.4, 221.3 ± 6.9 days, respectively. Oestrous duration was 41.1 ± 3.1 hours. The interval between furrowing and onset of oestrus was shorter in cross bred sows. There was no variation in valuesof oestrus cycle length and gestation length. The first service pregnancy rate was higher in both the local and crossbred sow. Number of piglets per sow per farrowing was 6.1 ± 2.2 and 60.9% local sows gave birth of 3 to 5 pigletsper farrowing whereas 75.0% cross bred sows gave birth of 6 to 9 piglets. These results suggest that reproductiveparameters of local sow need to be improved for better production, and cross bred sows should be reared for obtainingexpected productivity.

Feminist Participatory Action Research (FPAR)

Trimita CHAKMA 이화여자대학교 아시아여성학센터 2016 이화여자대학교 아시아여성학센터 학술대회자료집 Vol.2016 No.1

Women of the Asia Pacific region are amongst the most affected by the world’s intersecting crises of climate change, deepening inequalities, deteriorating democratic space and growing fundamentalisms. To equip women to address the impact of these challenges, Asia Pacific Forum on Women Law and Development (APWLD) works to empower local women’s movements. Since 2012 APWLD has supported 27 grassroots communities from 13 countries to build their capacity to document their experiences, concerns and demands using Feminist Participatory Action Research (FPAR). This paper will look at case stories of how FPAR as a tool has been helpful for achieving multiple impact objectives to bring about ‘structural change’ and strengthen feminist movements across the region under APWLD’s two programmes: Breaking out of Marginalization (BOOM), and Climate Justice (CJ).

Mechanistic analysis of sono-photolysis degradation of carmoisine

Sankar Chakma,Vijayanand S. Moholkar 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.33 No.-

The hybrid advanced oxidation process (AOP) of sono-photolysis, in which sonication and photolysis(UV-C/H2O2) are applied simultaneously, is known to give effective degradation of several biorecalcitrantpollutants. This study has attempted to identify the links and interactions between themechanisms of individual AOPs of sonolysis and photolysis, when applied simultaneously. Experimentalresults have been analyzed concurrently with the simulations of cavitation bubble dynamics. It isrevealed that oxidizing ( OH) radicals generated through photolysis contribute mostly to degradationreactions. Due to highly sporadic nature of transient cavitation, the contribution of sonolysis todegradation is rather subordinate as compared to photolysis. Nonetheless, faster degradation and highermineralization in sono-photolysis, as compared to photolysis alone, essentially points at supportive roleof ultrasound in the hybrid AOP. Addition of electrolytes (or salt) to the reaction mixture during sonophotolysistreatment causes effective partitioning of the pollutant molecules in the interfacial region oftransient cavitation bubble, which results in further enhancement of degradation kinetics andmineralization. Although the present study has employed Carmoisine as model pollutant, themechanistic principles identified in this study, and their manifestations in terms of degradation/mineralization of pollutants are applicable to any other bio-recalcitrant pollutant.

Is NGO Peacebuilding Risk-Free? A Case Study on Bangladesh

( Anurug Chakma ) 서울대학교 통일평화연구원 2019 Asian Journal of Peacebuilding Vol.7 No.2

The official end of armed hostilities between insurgents and the Bangladesh military in 1997, post-conflict development interventions by international donors and the Government of Bangladesh, along with a greater emphasis on local ownership over peacebuilding interventions, as expressed in the Rangamati Declaration (1998), have given birth to the onset of NGO peacebuilding in the Chittagong Hill Tracts (CHT). This article argues that the aid flow has not only transformed community-based organizations into project-based local NGOs, but has also bred a new generation of profit-oriented and donor-driven local NGOs. This article concludes that NGO implementation of development projects and advocacy for human rights, despite being mostly effective in its identification of local needs, is severely affected by three major risk factors: legitimacy, security, and sustainability.

Celecoxib is a non-steroidal, anti-inflammatory drug used in the treatment of pain and inflammation associated with rheumatoid arthritis, and several other inflammatory disorders. It is a class II compound according to the Biopharmaceutics Classification System owing to its low water solubility and high membrane permeability. The objective of this study was to improve the solubility and dissolution rate of celecoxib using solid surfactant technology that might be useful in developing solid dosage forms. Solid surfactant was developed by mixing and grinding together a liquid surfactant (Tween 80) with various inorganic carriers like FujicalinⓇ (Dibasic Calcium Phosphate Anhydrous), PineflowⓇ (Porous-structured Maltodextrin), NeusilinⓇ (Magnesium Alumino metasilicate) and AerosilⓇ (Colloidal Silicon dioxide) in a mortar and pestle in different ratios of liquid surfactant and the carrier to obtain solid surfactants. The celecoxib tablets prepared with solid surfactants were then evaluated for their solubility and dissolution properties. Among the fillers used, Fujicalin showed the highest solubilization capacity for celecoxib. The dissolution behaviors of various tablets prepared with solidified surfactants were compared to those of conventional celecoxib tablets in a simulated gastric fluid. Celecoxib tablets prepared using solidified surfactants showed improved dissolution behaviors when compared to the conventional counterparts. Fujicalin solidified Tween 80 was further analyzed by powder X-ray diffraction analysis, differential scanning calorimetry thermographs and reverse phase high performance liquid chromatography.

Feminist Participatory Action Research (FPAR) : An effective framework for empowering grassroots women & strengthening feminist movements in Asia Pacific

Trimita CHAKMA 이화여자대학교 아시아여성학센터 2016 Asian Journal of Women's Studies(AJWS) Vol.22 No.2

The intertwined crises of climate change, deepening inequalities, deteriorating democratic space and growing fundamentalisms have serious ramifications for the poor and marginalized women of Asia Pacific. To address the challenges of these crises, Asia Pacific Forum on Women, Law and Development (APWLD), a regional feminist network in Asia and the Pacific, is working to empower rural, indigenous, migrant and urban poor women in the region. Using the conceptual framework of Feminist Participatory Action Research (FPAR), APWLD is supporting some of the most affected grassroots communities to build their capacities by documenting their concerns, local experiences of human rights violations, recommendations for solutions, and engaging in advocacy. This paper will look at case stories of how FPAR has been helping to bring about structural change and strengthen feminist movements across the Asia Pacific region.
