Detection and controlling of acoustic (AC) phonon phase have been strenuous tasks although such capability is crucial for further manipulating thermal properties. Here, we present a versatile formalism for tracing AC nanowaves with arbitrary strain compositions by incorporating the nonlinear photoelasticity (PE) into…

Ukuran penampang benda uji balok adalah 100 mm x 150 mm dengan panjang 1400 mm. Tulangan longitudinal yang digunakan adalah tulangan polos berdiameter 10 mm dan…
Electron microscope (EM) is essential for the morphological description of small taxa, but also reveals taxa hitherto grouped under the same name although presenting marked ultrastructural differences: e.g., Cocconeis scutellum var. parva. The latter taxon has been interpreted differently by authors, while no type has…
أجريت تجربة حقلية في احدى المزارع الواقعة في محافظة بابل في منطقة ابي غرق وفي تربة مزيجة لمعرفة تأثير اضافة السماد العضوي ( مخلفات الدواجن ) والرش بالأحماض العضوية ( هيومك وفولفك اسد ) والتداخل بينهما في نمو وحاصل البطاطا، تضمنت ثلاث مستويات من السماد العضوي المضاف ( مخلفات الدواجن ) وهي 0 ، 5 ، 10 طن هـ-1 تمثل العامل…
The most common damages to reinforced concrete horizontal structures are cracks in the lower (stretched) zone. The impact of an aggressive environment on the reinforcement through cracks can lead to its corrosion, disruption of adhesion to concrete and lower strength of reinforced concrete structures. To prevent the d…
To assess the reliability of energy efficiency of multilayer insulating enclosing structures of products made of straw, their classification is proposed for quantitative and qualitative thermal, mechanical and environmental features. To identify the hierarchical relationships between the classified parameters, the mat…
Material research has been a major driving force in the development of modern nano-electronic devices. In particular, research in magnetic thin films has revolutionized the development of spintronic devices; identifying new magnetic materials is key to better device performance and new device paradigm. The advent of t…
The paper presents the analysis of the three-dimensional strain state for the cogging process of a forging (type: shaft) of the X6CrNiTi18-10 austenitic steel with the application of the finite element method. The results of the thermal-mechanical simulation of the hot cogging process on flat and shaped anvils, taking…
Technological progress in construction of automotive vehicles, particularly in construction of engines, enforces simultaneous changes in foundry properties of aluminum alloys used in automotive industry. Until recently, abrasion resistance was the main usability criterion of a material used for pistons for internal co…
The effect of low-alloy additions on low-C steels hardenability is reported. Various as-quenched materials with microstructures consisting of low-C (granular) bainitic (B), mixed bainitic (B)/martensitic (M) and fully martensitic microstructures were produced. Results show that for a given cooling rate, an increase of…
Rare earth ion ferrite RFe 2 O 4 (R = Y, Dy, Ho, Er, Tm, Yb, Lu, Sc, or In) has been attracted much attention due to its anomal physical properties as a candidate of electronic ferroelectric. Although most of reports were discussed by bulk sample, much effort has been made in fabricating film of RFe 2 O 4 recently. Fi…
In this theoretical work, the Raman spectra were analyzed by considering the origin of the G peak, its shape, position and relative intensity as a function of the number of graphene layers. By using the spectral moment’s method, the Raman spectra of mono, bi and few-layers of graphene are calculated and a good agreeme…
The influence of amorphous silica, plasticizer, water-repelling agent and integrated hydrophobic plasticizing additives on structural characteristics, physico-mechanical, hydrophysical characteristics and salt resistance of magnesia binders was studied. Some of the structural parameters (average and true density; dens…
Cobalt-based alloys are more and more considered for dental applications, instead the expensive noble alloys and the other predominantly based alloys based on the allergen element nickel. These alloys frequently contain chromium to allow good resistance against corrosion as this may take place in the buccal milieu. Th…

Abstract Reck encodes a membrane‐anchored glycoprotein implicated in the regulation of extracellular metalloproteinases, Notch‐signaling, and Wnt7‐signaling and shown to play critical roles in embryogenesis and tumor suppression. Precise mechanisms of its actions in vivo, however, remain largely unknown. By homologous…
We theoretically propose a three-dimensional (3D) plasmonic ruler based on orthogonal plasmonic gap modes which have different wavelengths. The ruler consists of three silver nanoblocks with two ten-nanometer air gaps. First, in a two-block structure, the lateral displacement of one block can be determined by the abso…
A new theoretical route employing the concept of chemical hardness has been developed to predict the surface tension γ and the changes of the standard enthalpies (CSEs) of sublimation ΔsH0 of alkali halides. The values of these quantities have been calculated by means of the ratios ηM/V1/3m where ηM and Vm are the mol…
In this paper, we have investigated the structural, electronic and optical properties of ZnAl2Te4 defect chalcopyrite semiconductor using generalized gradient approximation (GGA) within density functional theory (DFT). We have calculated the optimized lattice constants (a and c) and compared with the available experim…
Abstract We report a simple experiment to demonstrate optically-driven resonance on a macroscopic object. Utilising dynamic force microscopy in ambient environment, the resonant motion of a cm-sized cantilever driven by an amplitude-modulated diode laser is directly observed. Our versatile setup involves a host of exc…
