Kekosongan persediaan material pada saat pelaksanaan proyek dapat mengakibatkan penyelesaian suatu pekerjaan menjadi terhambat sehingga akan mempengaruhi total waktu serta biaya proyek. Apabila terlalu banyak maka membutuhkan ruang penyimpanan dan terjadi penyusutan yang berdampak meningkatkan biaya. Untuk menghindari hal tersebut perlu dibuat perencanaan efektif efisien dengan mempergunakan me...

In numerical control (NC)-based machining, NC data-based tool paths affect both quality and productivity. data are generated according to cutting conditions. However, causing excessive load can accelerate wear even result in damage. the opposite case, increasing machining time influence surface from perspective of dynamics machine tool–material–tool combination. There have been a lot studies on...

Prinsip utama dalam keberlanjutan adalah tercapainya perbaikan kualitas hidup manusia melalui sosial, ekonomi dan lingkungan. tersebut dapat diimplementasikan pada berbagai macam bangunan. Salah satunya Pasar ’X’ di Semarang yang mempunyai nilai cagar budaya. Implementasi diperlihatkan penggunaan material penanganan bangunan budaya pasca kebakaran. Bangunan kebakaran dialami oleh ‘X’ merupakan ...

The 41-residue synthetic ovine corticotropin-releasing factor (CRF; corticoliberin) has been shown to stimulate release of corticotropin (adrenocorticotropic hormone; ACTH) and beta-endorphin from AtT-20/D16-16 mouse pituitary tumor cells. Phospholipid methylation of phosphatidylethanolamine to phosphatidylcholine with S-adenosylmethionine as methyl donor has been suggested as a possible membra...

OBJECTIVES The aim of this study was to evaluate the oxidative status and DNA integrity in testes of wistar rat offspring exposed to omega-9 monounsaturated (MUFA) at different times of late organogenesis. MATERIALS AND METHODS Sixty female rats were divided into six groups of 10 animals. The first group served as control and received the drug vehicle, olive oil (1 ml/kg/day). The second, thi...

It is well known that anomaly cancellations for D16 Lie algebra are at the root of the first string revolution. For E8 Lie algebra, cancellation of anomalies is the principal fact leading to the existence of heterotic string. They are in fact nothing but the 6th order cohomologies of corresponding Lie algebras. Beyond 6th order, the calculations seem to require special care and it could be that...

BACKGROUND AND AIMS Periodontitis is a common chronic adult condition that implicates oxidative damage to gingival tissue, periodontal ligament and alveolar bone. This study aimed at assessing the association between the nitro-oxidative stress and the periodontal tissues destructions in experimental rat periodontitis. METHODS Periodontitis was induced in 15 male albino rats by repetitive lesi...

21 21 In view of evidence that Zn neurotoxicity contributes to some forms of pathological neuronal death, we developed a model of Zn neurotoxicity in a cell line amenable to genetic manipulations. Exposure to 500 mM ZnCl for 15 min under depolarizing conditions 2 21 resulted in modest levels of PC12 cell death, that was reduced by the L-type Ca channel antagonist, nimodipine, and increased by t...

Many studies on fiber reinforced polymer composite bars, as a substitute for reinforcing bars, have been conducted to solve corrosion of steel in reinforced concrete structures since 1960s’. However, FRP Bars have a lower elastic modulus than steel rebar as a structural component of concrete structures. Material properties with brittleness fracture and low elastic modulus can be improved by com...

Pyroelectric liquid-crystal polymers were prepared by photopolymerization of binary mixtures of two monomers that exhibit a smectic C* phase: A2c, 49-$(R)-(2)-2-[(10-acryloyloxy)decyl]oxy%-3-nitrophenyl 4-{48[(11-acryloyloxy)undecyloxy]phenyl%benzoate and A1b, 49-((R)-(1)-2-octyloxy)-39-nitro phenyl 4-(48-@(11acryloyloxy)undecyloxy]phenyl) benzoate. Both liquid-crystal monomers have a NO2 subst...
