. Biomassa atau cadangan karbon merupakan salah satu indikator kelestarian tegakan hutan. Kuantitas biomassa yang stabil dan proporsional mengindikasikan hutan berada dalam kondisi baik. Dalam rangka menjaga hutan, pihak-pihak terkait dituntut untuk selalu aktif di pemantauan satunya adalah tegakan. Penelitian ini bertujuan menguji sejumlah metode interpolasi spasial mengestimasi distribusi huj...

This paper proposes a new methodology for the optimal allocation and sizing of Embedded Generation (EG) employing Real Coded Genetic Algorithm (RCGA) to minimize the total power losses and to improve voltage profiles in the radial distribution networks. RCGA is a method that uses continuous floating numbers as representation which is different from conventional binary numbers. The RCGA is used ...

Internationally exploited lubricants are derived from coal and petroleum. Due to their high consumption and effects of their long-term pollution on the environment, it is imperative to use renewable and cheap feedstock for the synthesis of bio-based lubricants. This study presents the synthesis and optimization process of Ethylene Glycol (EG) based bio-lubricant from palm kernel oil. Palm Kerne...

In this study, we applied proton NMR to measure the permeation of two cryoprotective agents (CPAs), ethylene glycol (EG) and methanol, into 1st instar Anopheles larvae. Calibration with standard solutions of EG or methanol (0-10 mol l(-1)) confirmed the reliability of the NMR measurements for determining the concentration of these solutes. To assess permeation, larvae were immersed in 1.5 mol l...

We consider extremal graph-theoretic problems on regular structures. The problems ask to maximize a certain parameter of the structures in question under the condition that the values of some other parameter(s) are constant. This is where the term isoparametric is taken from. The graph problems we consider are edge-isoperimetric problems, and the poset problems are dealing with the notion of Ma...

Background/Objective The aim of this study was to examine the effect of sprint cycling training on the intermittent run performance, sprinting speed, and change of direction (COD) ability of recreational intermittent sports athletes. Methods Sixteen participants participated in the study. The experimental group (EG, n = 8) received a total of 12 sessions of sprint cycling training in a 4-week...

Background: The aim of the study was to compare the effects of two different concentrations of cryoprotectants by Cryotop vitrification on survival and Heat shock protein 72 (Hspa1a) expression of two-cell mouse embryos. Materials and Methods: Different cryoprotectants’ concentrations of the combination of dimethyl sulfoxide (DMSO) and ethylene glycol (EG) were used and compared with each other...

Low pressure radio frequency plasma-assisted deposition of 1-isopropyl-4methyl-1,4-cyclohexadiene thin films was investigated for different polymerization conditions. Transparent, environmentally stable and flexible, these organic films are promising candidates for organic photovoltaics (OPV) and flexible electronics applications, where they can be used as encapsulating coatings and insulating ...
