Optimization of Energy Efficiency and Conservation in Green Building Design U...Totok R Biyanto
The development of green building has been growing in terms of both design and quality. The development of green building bariered by the issue of expensive investment. Actually, green building can reduce energy usage in the building especially in utilization of cooling system. External load plays as major role of reduction in the use of the cooling system. External load is affected by type of wall sheathing, glass and roof. The proper selection of wall, type of glass and roof material are very important to reduce external load. Hence, the optimization of energy efficiency and conservation in green building design is required. Since this optimization consist of integer and non-linear equations, this problem fall into Mixed-Integer-Non-Linear-Programming (MINLP) that required global optimization technique such as stochastic optimization algorithms. In this paper the optimized variables i.e. type of glass and roof were chosen using Duelist, Killer-Whale and Rain-Water Algorithms to obtain the optimum energy and considering the minimal investment. The optimization results exhibited the single glass Planibel-G with the 3.2 mm thickness and glasswool insulation provided maximum ROI of 36.8486%, EUI reduction of 54 kWh/m2·year, CO2 emission reduction of 486.8971 tons/year and reduce investment of 4,078,905,465 IDR.

INDUSTRIAL WASTE HEAT USED IN TYPICAL THERMAL POWER PLANTIAEME Publication
An advanced waste heat and water recovery technology has been developed to extract a portion of the water vapor and its latent heat from flue gases based on a nonporous ceramic membrane capillary condensation separation mechanism. The recovered water is of high quality and mineral free, therefore can be used as supplemental makeup water for almost all industrial processes. The technology was first developed and proven at industrial demonstration scale for gas-fired package boilers,

Altered Terrain: Colonial Encroachment and Environmental Changes in Cachar, A...PriyankaKilaniya
The beginning of colonial policy in the area was signaled by the British annexation of the Cachar district in southern Assam in 1832. The region became an alluring investment opportunity for Europeans after British rule over Cachar, especially after the accidental discovery of wild tea in 1855. Within this historical context, this study explores three major stages that characterize the evolution of nature. First, it examines the distribution and growth of tea plantations, examining their size and rate of expansion. The second aspect of the study examines the consequences of land concessions, which led to the initial loss of native forests. Finally, the study investigates the increased strain on forests caused by migrant workers' demands. It also highlights the crucial role that the Forest Department plays in protecting these natural habitats from the invasion of tea planters. This study aims to analyze the intricate relationship between colonialism and the altered landscape of Cachar, Assam, by means of a thorough investigation, shedding light on the environmental, economic, and societal aspects of this historical transformation.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
