California would take the first step toward eliminating legal requirements for flame-retardant chemical additives in plastic foam building insulation, under a bill before Gov. Edmund G. (Jerry) Brown Jr. (D). He is expected to sign it. Plastic foam insulation is a key component of many commercial and residential build…
Fazit Mit der kontrastverstärkten, T2-gewichteten 3D-MR-Angiografie (ESWAN) ließen sich Veränderungen der Hirnvenen bei Patienten mit schubförmig remittierender MS darstellen. Nach Ansicht der Autoren unterstützen diese Beobachtungen die Vorstellung, dass partielle hämodynamische Veränderungen und der Hypometabolismus…
In this paper we present the structural, optical and electrical characteristics of ZnO thin films grown for different parameters by the atomic layer deposition (ALD) method. The films were grown on glass and silicon substrates at low temperatures. We used diethyl-zinc (DEZn) and deionized water as zinc and an oxygen s…

In the recent years use of nanotechnology has increased, including many new materials containing nanoparticles. Nanoparticles are defined as materials smaller than 100 nm, in one dimension at least. Their biological activity is not yet fully known. Due to their small size, but large surface area, nanoparticles can ind…
A catalytic monolith reactor can be modeled using direct numerical simulation, where all the length scales within a monolith reactor are resolved.This, however, requires the use of a fine grid with millions of cells, which makes it computationally prohibitive.The objective of this thesis is to develop a reduced model…
The use of mouthwashes in the postoperative time after the placement of dental implant is essential to reduce the colonization of microorganisms in the peri-implant region. However, the oral environment is constantly exposed to the acids that can collaborate with the corrosive process of titanium. This study aimed to…
به منظور بررسی اثرات پرایمینگ اسمزی بر جوانه زنی بذر ذرت دو رگ سینگل کراس704 (K.SC 704)، آزمایشی به صورت فاکتوریل در قالب طرح پایه بلوک های کامل تصادفی با سه تکرار اجرا گردید. تیمارها شامل پرایمینگ بذر با محلول های پلی اتیلن گلایکول (PEG6000) با غلظت های 5 و 10 درصد، نیترات پتاسیم (KNO3) با غلظت های 1 و 2 درصد و کلرید…
The orbital structure of the quantum Hall ferromagnetic states in the zero-energy Landau level in chiral multilayer graphene (AB, ABC, ABCA, etc. stackings) is determined by the exchange interaction with all levels, including deep-lying states in the Dirac sea. This exchange field favors orbitally coherent states with…
Andreas Schmid has a Ph.D. in Biochemical Engineering-Environmental Engineering and now is a full Professor in water and wastewater treatment at the Faculty of Engineering at the University of Applied Sciences Hof, Germany. More than 20 years of working experiences in industry built the fundament to derive applied sci…

Telahdilakukanpenelitianmengenai pengaruh perlakuan panas, variasi suhu tempering dan lama waktu penahanan terhadap kekerasan dan struktur mikro baja pegas daun karbon sedang. Bahan utama yang digunakan pada penelitian ini adalah pegas daun. Pengambilan data meliputi uji komposisi kimia, kekerasan dan struktur mikro d…
We report on a Dirac-like Fermi surface in three-dimensional bulk materials in a distorted spinel structure on the basis of density functional theory (DFT) as well as tight-binding theory. The four examples we provide in this paper are BiZnSiO4, BiCaSiO4, BiMgSiO4, and BiAlInO4. A necessary characteristic of these str…
این تحقیق با هدف بررسی تأثیر استفاده از پلیآمینوآمید اپیکلروهیدرین (PAE) و کربوکسیمتیلسلولز (CMC) بر مقاومتهای مکانیکی خشک و تر کاغذهای ساخته شده از خمیر بکر انجام شد. در این مطالعه از پلیآمینوآمید اپیکلروهیدرین (PAE) در سه سطح وزنی (0، 5/0 و 1 درصد) و کربوکسیمتیلسلولز (CMC) در 4 سطح وزنی (0، 5/0/، 1 و 5/1 د…
یکی از مهمترین خواص کاغذهای بهداشتی، مقاومت به کشش در حالت تر آنها میباشد، برای این منظور پلیآمید اپیکلروهیدرین در سطح گستردهای در صنعت کاغذ بهداشتی برای ایجاد و حفظ مقاومتتر در کاغذ استفاده میشود. در این مطالعه اثر مقدار و کاربرد ترکیبی ماندگار کننده (RTN) و کربوکسی متیل سلولز (CMC) همراه با پلیآمید اپی…

A mesoscopic model is introduced for shear plasticity of disordered materials. Plastic deformation is assumed to result from series of local reorganizations. The structural disorder is modeled by spatial fluctuations of plastic thresholds on a discretized lattice. The elastic interaction induced by local rearrangement…
We show how nuclear magnetic spin-lattice relaxation dispersion of proton-water (NMRD) can be used to elucidate the effect of cellulose ethers on water retention and hydration delay of freshly-mixed white cement pastes. NMRD is useful to determine the surface diffusion coefficient of water, the specific surface area a…
The Saltstone Production Facility has a 10-inch Readco-Kurimoto continuous mixer that mixes the premix dry feeds and low-level waste salt solution to make fresh (uncured) saltstone. Inspection of the mixer in January 2013 showed significant wear on the third, fourth and fifth paddle pairs after the conveying augers. A…
