Obrada metala struganjem je jedan od najvažnijih proizvodnih procesa zato što pripremci dobijeni livenjem, kovanjem ili nekim drugim metodama obrade zahtevaju naknadnu obradu rezanjem kako bi se dobio finalni proizvod.\nU ovom radu, postavljen je nov model ortogonalnog rezanja koji pored sila za formiranje strugotine…
In this paper we prove for rank one perturbations that negative two times reciprocal of the imaginary part of resonance point is equal to the rate of change of the scattering phase as a function of the coupling constant, where the coupling constant is equal to the real part of the resonance point. This equality is in…
Solubility of β-diketone (4-ethyl-1-phenyl-1, 3-octadione, abbreviated as HA, C 16 H 22 O 2, molecular weight, 246.34)–ZnSO 4 –(NH 4 ) 2 SO 4 –NH 3(aq) –H 2 O system at T = (298.15, 308.15) K is elaborately measured by isothermal method. The results show that the solubility of ZnA 2(o), NH 4 A (o), H 2 O (o), Zn 2+ (w…
Bu çalışmada, CAS kayıt numarası 63148-58-3 olan silikon yağı kullanılarak bakteriyel selüloz (BC) üretiminde verime olan etkisi incelenmiş ve bazı özelliklerine bakılarak literatür ile karşılaştırılmıştır. Bu amaçla, hazırlanan Hestrin ve Schramm (HS) ortamına Gluconacetobacter hansenii (Kontrol-BC) ve Gluconacetobac…
The effects of magnetic dilution and applied pressure on frustrated spinels GeNi2O4, GeCo2O4, and NiAl2O4 are reported. Dilution was achieved by substitution of Mg2+ in place of magnetically active Co2+ and Ni2+ ions. Large values of the percolation thresholds were found in GeNi(2-x)MgxO4. Specifically, pc1 = 0.74 and…
The simplest way to obtain thin carbon layers is to draw or rub with a graphite rod. During rubbing, forces of friction acting in graphite/substrate tribological system cause drastic changes in the structure of the interface stratum developing thereby stable self-organized and ordered thin structure. We present a pion…
Fabricating new functional materials has always been at the center of colloidal science, and how to form circular rings is a meaningful challenge due to their special electronic, magnetic and optical properties. Magnetic colloidal spheres can self-assemble into rings, but these rings have an uncontrollable length and…
Recent experiments reveal that the strained bulk HgTe can be regard as a three-dimensional topological insulator (TI). Motivated by this, we explore the strain effects on the magnetotransport properties of the HgTe surface states at magnetic field. We analytically derive the zero frequency Hall and collisional conduct…
Análise do promotor quimérico regulado por zinco para a expressão de proteínas recombinantes em Saccharomyces cerevisiae.
Dört tekerlekten çekişli bir taşıta ait sabit ön aksta kullanılması düşünülen diferansiyel kovanının kütle ve gerilme optimizasyonu gerçekleştirilmiştir. Bu amaçla önce, sabit aksın parametrik katı modeli oluşturulmuştur. Bu model yardımıyla, farklı sürüş koşullarının etkileri de dikkate alınarak, aksın sonlu elemanla…
En las ultimas decadas, la colada semicontinua ha mantenido una posicion prominente en el procesamiento de aleaciones de aluminio comerciales especialmente en la produccion de lingotes. Es por ello que la industria nacional requiere desarrollar investigaciones que propongan soluciones tecnicas viables que mejoren la p…

This chapter discusses the organic nanoparticles and aggregates for drug and gene delivery. Inspired by cells that are able to perform multiple complex reactions within confined environments owing to their internal subcompartment structure, the development of multicompartment vesicles fulfilling simple predefined cell…
The study of the relationship between polymer materials or composites, their structure and behavior on the one hand and their processing conditions on the other hand, is a multidisciplinary science. The heat transfer during processing of polymer and/or composites materials plays an important role. This chapter provide…
Interpenetrating polymer networks (IPNs) and related materials represent one of the fastest-growing fields in polymer science. It is widely used in the transportation, consumer, industrial, hygiene, and medical sectors where they provide decorative finish, high resilience, high tear strength, and so forth. Toward the…
This chapter reviews several available energy storage technologies that can be used in electric power systems. It details the operating principles, the main components, and the most relevant characteristics of each technology. In order to obtain an overview of the main characteristics of the energy storage technologie…
The control of manufacturing processes of organic matrix composite materials is strongly related to the temperatures and thermal properties of the samples to be processed. Two kinds of approaches are to be considered: the contact methods generally considering a surface instrumentation besides the process or a radiativ…
Nanomaterials with controlled physical, chemical, and biological characteristics can be used for the therapy of the specific causes of the diseases. There are several ways to develop new materials in nanometer scale. Mainly, top-down and bottom-up approaches are the two major techniques to produce nanomaterials. Depen…
Training classes for nuclear criticality safety, MCNP documentation. The need for, and problems surrounding, validation of computer codes and data area considered first. Then some background for MCNP & Whisper is given--best practices for Monte Carlo criticality calculations, neutron spectra, S(α,β) thermal neutron sc…
This chapter overviews the attempts in understanding the biocompatibility of nanomaterials and provides an account of how these views changed in light of recent findings, with emphasis on the methodology used in nanotoxicology studies. The excretion and clearance of engineered nanomaterials (ENMs) is discussed in the…
