During sputter deposition of metal layers bulges at sharp convex corners can arise and are observed after metalization of contact holes for semiconductor circuits. We present an explanation of this phenomenon by assuming that in process steps prior to the deposition a ledge is formed . This assumption together with the choice of an appropriate model for the distribution of the incident particle...

Information about the position and movement of the body with respect to the external environment is vital for normal bodily function. It allows us, for example, to walk and run upright without falling over, and at the same time to maintain steady fixation on an object that may itself be moving. The speed and precision with which the mammalian brain can gather and use this information is evident...

In Slovenia we can find dffirent levels of implementation of integration forms into the teaching, practice, both regarding the strategies of integration as well as professional andfinancial solutions. The present article introduces the projec.t of Integration oJ'Hearing Impaired Children into a Regular Primary School in Maribor, currently running under the supervision of the Slovene Board oJ'Ed...

A 71-year old patient with a history of minimal periodontal attachment loss presented with an asymptomatic, non-bleeding, isolated deep pocket on the mesio-facial of a central incisor. Such localized, deep pockets are most frequently associated with a root fracture or an abscess, but in this case an atypical ledge-like projection determined to be a cemental tear was detected at the base of the ...

We extend the McPherson model for Si-O bond-breakage energetics, which considers only a single SiO4 tetrahedron, in a way to capture the effect of the whole crystal. No ledge in the direction assumed in the McPherson model was revealed. Instead, potential profiles feature a saddle point in a different direction. The activation energy for bond-breakage is found to be rather high (~ 6 eV). This s...

It has been conventional wisdom that early deprivation and trauma can lead unequivocally to later adult debilitation and disorder. That this is not in fact the case has become abundantly clear via a variety of recent new research. While early adversity can be a severe impediment, there is a myriad of accounts of people who have been born into lives of abject destitution, yet have grown into sta...

The sharpshooter genus Cavichiana Mejdalani et al., 2014 included so far only two species of about 6-8 mm in length: C. bromelicola (type species) and alpina Quintas 2020. Both are bromeliad specialists from southeastern southern Brazil. Here a third species, caelivittata sp. nov., is described illustrated based on males females the Serra dos Órgãos massif state Rio de Janeiro, new specialist c...

In the paper analytical optimization of discontinuous grinding parameters according to temperature criterion is carried out and on its basis conditions for significant reduction cutting temperature, which consist mainly in increasing number contacts working ledges wheel with fixed cross-section machined workpiece, are determined. It established by calculations that providing 20 may be reduced u...

Burnt deposits are an important source of information on ancient lifestyles, providing the possibility reconstructing size, intensity use, and functions fi replaces at prehistoric settlements, to assess fuel sources. We outline results a multidisciplinary study their contexts Surungur—a stratifi ed site in Fergana Valley, southern Kyrgyzstan. Sixteen samples from ash lenses intermediate were st...
