The formation of continuous patterns of nanostructured materials using directed self-assembly under external fields has generated considerable current research interest. We demonstrate for the first time such continuous patterning by inducing irreversible self-assembly leading to nucleation in mesocopic materials (inorganic, organic, and nanoparticles) using a tightly focused laser beam in an o...

BACKGROUND The evidence and method are limited for the associations between mortality and temperature variability (TV) within or between days. OBJECTIVES We developed a novel method to calculate TV and investigated TV-mortality associations using a large multicountry data set. METHODS We collected daily data for temperature and mortality from 372 locations in 12 countries/regions (Australia...

کامپوزیتها دسته ای از مواد پیشرفته هستند که بدلیل خواص مهندسی عالی آنها روز به روز بر کاربرد آنها افزوده می شود. کامپوزیتهای زمینه فلزی به روشهای گوناگون تولید می گردند. تنها کامپوزیتهایی که به روش های درجا یا in-situ تهیه می شوند از پایداری ترموشیمیایی بالایی برخوردارند. روش آلیاژ-آلیاژ یکی از روشهای تولیدی است که فاز دوم می تواند به صورت درجا در زمینه کامپوزیت تشکیل شود. در این تحقیق کامپوزیت...

Aim: To demonstrate an algorithmic approach to hypospadias repair with the aid of the surgical microscope as a teaching aid, as well as an ergonomic tool. Methods: One hundred and two patients were operated on between 2009 and 2013, all by the senior surgeon (M Dalal). This is a retrospective review of results in the case series. The procedures used were one stage repair with no incision of the...

The hemizonid (6) is a ventro-lateral, commissure (7) which extends around the ventral side of nematodes between the hypodermis and the cuticle, stopping at the lateral fields (2, 4, 6, 8). Although the hemizonid has been recorded mainly from plant parasitic nematodes (1,4, 6, 7, 8), Timm (11) reported its presence in a wide variety of nematodes and suggested that it may be present t h r o u g ...

The detrimental precipitation at the 2205 duplex stainless steel (DSS) grain boundaries has characterized material to have poor workability after being hot-rolled. However, in microstructure is largely influenced by cooling rate or method. There an insufficient investigation of this steel's grade interfaces and rationale its workability. This study investigates influence heat treatment hot-roll...

Is the Introspection Thesis true? It certainly isn’t obvious. Introspection is the faculty by which each of us has access to his or her own mental states. Even if we were to suppose that mental states are identical to brain states, it doesn’t follow immediately from this supposition that we can introspect our mental states as brain states. This point is analogous to the following. It doesn’t fo...

This paper aims to improve the mechanical properties and fatigue life of AISI/SAE 4140 alloy steel connecting rods (CRs). Conventional CRs are typically manufactured through open die forging/hammering, blocking, hot forging processes. In present work, a modification process route has been proposed such that forging/hammering was completely replaced with multistep asymmetrical reducer rolling te...

The solid state track detector of celluloid films (cellulose nitrate+camphor 25% an weight) using etching technique is suitable for low energy alpha particle detection . The critical rate of energy loss for track formation in celluloid films is determined as 1 .3 MeV/mg•Ecm2. Irradiated samples are etched in NaOH (6 N) solution at 46•Ž for 10 minutes . The etched tracks are observed under a vie...

Hot electrons injected into antiferromagnetic Mn layers from the tip of a low temperature scanning tunneling microscope have been used to determine the energies, lifetimes, and momenta of antiferromagnetic spin waves on the nanometer scale. The spin waves show a linear dispersion with a velocity of 160+/-10 meV A and lifetimes that scale linearly with energy in agreement with neutron scattering...
