The present study was undertaken to examine the viability, motility and morphology of spermatozoa that were frozen-thawed at different temperature followed by the storage at 4oC until 10 hours under the condition of tropical area. The frozen semen derived from a Holstein-Friesian bull with the egg-yolkbase extender was thawed at 23oC or 37oC for 30 seconds or 15 seconds, respectively, and kept ...

Ki Aksara merupakan jenis Anggrek tanah yang dilindungi pemerintah. Keberadaan unik ini mulai berkurang karena terjadi perubahan habitat seperti penebangan liar, kebakaran hutan, dan aksi perburuan liar tidak memperhatikan aspek kelestarian. Penelitian dilaksanakan untuk mengetahui distribusi ki di Resort Ranu Darungan Taman Nasional Bromo Tengger Semeru. menjadi tiga blok pengamatan, berdasark...

Twenty-four rectangular RC column specimens, constructed at 1/3 scale, were tested under axial loading to investigate the use of ASWM (one, two, three, four, and five layers) exposed elevated temperatures. Six specimens subjected laboratory temperature (control or un-damaged specimens) 23oC. Eighteen temperatures (six columns 250oC, six 500oC, 750oC) for 2 hr. The obtained results clearly showe...

Background. Acrylic resins used in restorative dentistry are the most popular denture base material, because they have good optical properties and small solubility in body fluids. However their mechanical properties are limited and therefore acrylic resins require different methods of reinforcement one of which can be application of different kinds of fibers. Objectives. To investigate the effe...

The decline in the availability and alarming pollution of the existing water resources is the major environmental problem of third-world countries. The main reason of water pollution is the disposal of untreated industrial effl uents. This study was designed to evaluate the pollution load caused by a paper mill, and to propose a wastewater treatment plant design, based on the analyses of wastew...

BACKGROUND Physical exercise is known to be a stressor stimulus that leads to reproductive disruption. OBJECTIVE The aim of this study was to evaluate the effect of forced swimming on the uterus and ovaries in mice. MATERIALS AND METHODS Adult mice (N=24) were divided into the following three groups: A, control; B, swimming in water (10oC); and C, swimming in water (23oC). Swimmers swam for...

Interest in seed propagation of drumstick tree (Moringa oleifera) has created a need for information about the water relationships of its seeds. Thus, we studied the imbibition and desiccation kinetics and adsorption/ desorption isotherms of drumstick tree seeds. Seeds absorbed water readily when imbibed at 23oC. After 17 h of exposure to an atmosphere of 100% relative humidity (RH), seed moist...

Trichostrongylus colubriformis is an important cause of parasitic gastroenteritis in ruminants, where it causes protracted diarrhoea, rapid loss of weight, loss of production and death. The in vitro efficacy of extracts of Peltophorum africanum was determined against this parasitic nematode. Eggs and larvae of T. colubriformis were incubated at 23oC in the extracts of the leaf, bark and root of...

Meningginya konsumsi energi tidak terbarukan tiap tahun terutama minyak bumi sedangkan cadangan di Indonesia semakin menipis dan meningkatnya penggunaan plastik yang seimbang dengan pengolahan limbah merupakan masalah dihadapi saat ini. Salah satu upaya dapat menangani permasalahan tersebut adalah metode pirolisis. Melalui pirolisis, diolah aman menjadi produk cair bisa alternatif sumber bahan ...

The high temperature stress-induced changes in chlorophyll a fluorescence parameters were used to study heat tolerance in nine accessions of common bean (Phaseolus vulgaris L.) received from the germplasm collection of “Maritsa” Vegetable Crops Research Institute and the Invstitute for Introduction and Plant Genetic Resources. The bean plants were treated for 2h at two temperatures, 23oC and 45...
