The distribution of glycosaminoglycans (GAGs) in different functional regions (weight-bearing and nonweight-bearing portions) of the human hip joint cartilage was studied. The results obtained were as follows: (1) Weight-bearing cartilage contains larger amounts of GAGs than nonweight-bearing, cartilage. (2) Weight-bearing cartilage contains keratan sulphate in higher ratio to chondroitin sulph...

background: it has been claimed that by using different washing methods, the sperms can be separated according to size, motility, density, chromosomal content and surface markings and charge. these methods also reduce sperm chromatin deficiencies and screen the sperms before applying in assisted reproduction techniques. objective: this study compared simple density gradient methods and a combin...

Seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. This devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.The base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...

Selective mortality, whether caused naturally by predation or through the influence of harvest practices, initiates changes within populations when individuals possessing certain heritable traits have increased fitness. Theory predicts that increased mortality rates will select for changes in a number of different life history characteristics. For example, fishing often targets larger individua...

Tanah lempung ekspansif di Desa Oebelo merupakan tanah dengan potensi kembang susut yang besar dan sering menyebabkan kerusakan struktur. Penelitian ini dilakukan sebagai upaya perbaikan melalui stabilisasi secara kimiawi menggunakan kapur, fly ash bottom ash. Tujuannya adalah untuk mengetahui pengaruh tersebut terhadap sifat fisik mekanis tanah, serta kapasitas dukung maksimum dihasilkan nilai...

The construction industry remains a significant contributor to global carbon emissions. Several sustainable alternatives have emerged overcome this issue in geotechnical engineering. In study, cellulose, an abundant biopolymer, is investigated for its potential modify properties favourably. Sodium carboxymethyl cellulose (NaCMC) anionic ether derivative of natural with good binding and moisture...

Research have shown how electrokinetic remediation (EKR) technology attempts to tackle the challenge of soil contamination by crude oil. However, suitability resulting remediated soils for use in road construction not been well reported. This work investigates engineering properties filter media enhanced oil contaminated (COCS) with a view ascertain its comparing performance charcoal and active...

Abstract Generally, the existence of soft soil in Indonesia will be a problem construction highway construction. One factor that influences and needs to known road is characteristics subgrade where pavement placed on it. Poor can cause bumpy surfaces, cracks, or other damage. Therefore, before carrying out improvement, it necessary know its through physical mechanical properties subgrade. This ...

Pre-determining fetal sex is against the random and equal opportunity that both conceptus sexes have by nature. Yet, under a wide variety of circumstances, populations shift their birth sex ratio from the expected unity. Here we show, using fluorescence in situ hybridization, that in a population of pygmy hippopotamus (Choeropsis liberiensis) with 42.5% male offspring, males bias the ratio of X...
