Lociranje opasnih materija sa konstantnim i promenljivim radijusima uticaja / Locating dangerous goods with constant and variable impact radii / Размещение опасных материалов с постоянным и переменным радиусом воздействия

open access: yesVojnotehnički Glasnik, 2016
Donošenje odluka o prostornom raspoređivanju opasnih materija neophodno je zbog minimiziranja rizika po okolinu. U ovom radu razmatran je problem lociranja različitih vrsta opasnih materija (sa različitim karakteristikama).

Down‐regulation of Shh in the hair follicles of mice during chemotherapy‐induced hair loss is mediated by the JAK/STAT1 signaling pathway

open access: yesFEBS Open Bio, EarlyView.
We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Explosive volcanic deposits on Mars: Preliminary investigations [PDF]

open access: yes
Two investigations were undertaken to examine possible large scale explosive volcanic deposits on Mars. The first includes an analysis of Viking Infrared Thermal Mapper (IRTM) data covering the vast deposits in the Amazonis, Memnonia, and Aeolis regions.

Minerals in Afghanistan : rare-metal deposits [PDF]

open access: yes, 2007
In Afghanistan rare metals (lithium, caesium, tantalum and niobium) occur in three main deposit types: pegmatites, mineralised springs and playa-lake sediments (Figure 1).

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

NATURAL RESOURCES – A REAL OR HYPOTHETICAL OBJECT OF ACCOUNTING [PDF]

open access: yesScientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2013
Nowadays natural resources have a controversial accounting treatment which is caused, firstly, by neglecting their inherent properties and, secondly, by a free and one-sided interpretation of the legal framework.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (
