Consolidation of disaster and development studies as an integrated field of action research that influences policy has proved to be fundamental to global disaster risk reduction, sustainable development, climate change, and humanitarian agreements. However, challenges in achieving targets, such as those of the Sendai Framework for Disaster Risk Reduction 2015–2030 and the Sustainable Development Goals, requires further advances of the disaster and development paradigm underpinning these aspirations. This article presents perspectives that grew primarily from local action research, particularly research carried out with marginalized and highly at-risk groups of people in Southern Africa and South *** fronts from these findings emphasize disaster and development risk assessment opportunities that consolidate earlier ideas and extend understanding of disaster and development-related risk intervention options. These acknowledge severe shortcomings in disaster risk reduction progress while including greater use of hope as an active ingredient. This process of paradigm exploration remains fundamental to achieving disaster risk reduction, sustainable development, and associated policy objectives. The analysis presented here reiterates earlier groundings in people-centric perspectives, emphasizing social relations and systems of meaning as essential active ingredients for challenging power structures, technology, education, and human behavior. The analysis proposes some consequent thematic fronts for increased investment. These includeinvesting in early buildup of well-being before a disaster,better living with uncertainty, and overcoming the barriers to desired disaster and development outcomes. The article is intended to contribute to an ever-evolving paradigm of disaster and development risk that requires impetus from personal and collective values beyond calculations of disaster and development.

Prostate cancer （PCa） is the most common malignancy in men. Prostate being an androgen responsive tissue, androgen deprivation therapy （ADT） is used in the management of locally advanced （improves survival） and metastatic （improves pain and quality of life） PCa. Over the past two decades, the use of ADT has significantly increased as it is also being used in patients with localized disease and those experiencing biochemical recurrences, though without any evidence of survival advantage. Hypogonadism resulting from ADT is associated with decreased muscle mass and strength, increased fat mass, sexual dysfunction, vasomotor symptoms, decreased quality of life, anemia and bone loss. Insulin resistance, diabetes and cardiovascular disease have recently been added to the list of these complications. As the majority of men with PCa die of conditions other than their primary malignancy, recognition and management of these adverse effects is paramount. Here we review data evaluating metabolic and cardiovascular complications of ADT.

Recently, mixture of different oils at various proportions have been used as feedstock for biodiesel production. The primary aim is to improve fuel properties which are strongly influenced by the fatty acid composition of the individual oil that makes up the feedstock mix. The tropics are renowned for abundant oil-bearing crops of which palm kernel oil （PKO） from palm seed and groundnut oil （GNO） are prominent. This present paper investigated biodiesel production from hybrid oil （HO） of PKO （medium carbon chain and highly saturated oil） and GNO （long carbon chain and highly unsaturated oil） at 50/ 50 （v/v） blending. The principal fatty acids （FAs） in the HO are oleic （35.62%） and lauric acids （24.23%） with 47.80% of saturated FA and 52.26% of unsaturated FA contents. The chemical conversion of the oil to methyl ester （ME） gave 86.56% yield. Fuel properties of hybrid oil methyl ester （the HOME） were determined in accordance with standard test methods and were found to comply with both ASTM D6751 and EN 14214 standards. The oxidative stability, cetane number and kinematic viscosity （KV） of HOME were observed to be improved when compared with those of GNO methyl ester from single parent oil, which could be accredited to the improved FA composition of the HO. The KV （3.69 minE/s） of HOME obtained in this paper was remarkably low compared with those reported in literature for most biodiesels. This value suggests better flow, atomization, spray and combustion of this fuel. Conclusively, the binary blend of oils can be a viable option to improve the fuel properties ofbiodiesel feedstock coupled with reduced cost.

The dispersion was evaluated using particle size,particle morphology,pH and encapsulation *** drug formulation with highest encapsulation efficiency was selected and used for the release studies and compared with the release from a commercial dosage form(Halfan~? 250 mg tablet,Claxo-Smithkline,Mayenne France) using simulated gastric fluid(SGF pH 1.2), simulated intestinal fluid(SIF pH 7.2) and phosphate buffer(pH 6.8) as biorelevant media. Results were analyzed statistically and the level of significance was taken to be P<0.05). Results:Discrete and spherical solid lipid microspheres were *** particle size of the dispersion was low(32.48-33.87μm) with minimal particle growth and high encapsulation efficiencies(86.8%-91.0%) after 3 *** pH of the microspheres dispersion changed appreciably after 3 *** vitro release result obtained revealed sustained and controlled drug release from the lipid microspheres compared with the tablet dosage ***: Formulation of hal of antrine as solid lipid microspheres presents a better alternative to the conventional tablet formulation as the in vitro dissolution of the highly lipophilic hal of antrine was highly improved.
