Due to the continuous creation of organic granular fertilizers new composition, there is a lack knowledge about their properties and influence norm on spreading efficiency. To increase efficiency use fertilizers, aims are properly choose most rational parameters fertilizer norms, considering characteristics fertilizer. determine this quickly with lower costs, various theoretical models computer...

This study was done to evaluate new manufactured rotary spreaders one made from stainless steel material and second from nickel titanium and compared them with conventional finger spreader for their affect on the amount of gutta percha (in mg) that can be applied to fill the root canal and evaluation of apical extension of first, second, third and fourth auxiliary gutta percha cones for the sta...

In this paper, considering the multifactor influence of knowledge dissemination process, a new ignorant-knower-spreader-forgetter (IKSF) model is proposed, which considers internalization mechanism, degradation communication, and willingness, as well time-varying uncertain parameters. First, we prove that loss equilibrium globally asymptotically stable when basic reproduction number <math xmlns...

INTRODUCTION: Correction of the hump nose entails more than just simple elimination of the dorsal hump. Recent trend is toward conservative reduction of the hump and appropriate adjustment of the radix height. East Asians often present with pseudo-hump, due to underprojected radix or tip, which accentuates the height of the hump. This study introduces our method of pseudohump correction and ach...

The role of obturation in root canal treatment, although considered secondary to debridement and disinfection, still remains a critical stage for a successful outcome. The aim of obturation is to seal the periradicular tissues from the residual microorganisms left in the root canal system after chemomechanical debridement. Obturation of the root canal space has been performed using various tech...

Introduction / objectives MRSA prevalence is low in nursing homes (NH) in the Netherlands. However, outbreaks in NH are usually larger than those occurring in hospitals. The national MRSA database shows that in the last three years 24% of the outbreaks occurred in NH. The NH under investigation experienced outbreaks in 2007 and 2010. Two residents and one health care worker (HCW) were involved ...

Compartmental epidemiological models have been developed since the 1920s and successfully applied to study the propagation of infectious diseases. Besides, due to their structure, in the 1960s an interesting version of these models was developed to clarify some aspects of rumor propagation, considering that spreading an infectious disease or disseminating information is analogous phenomena. Her...

Detecting spreaders, or scan sources, helps intrusion detection systems (IDS) identify potential attackers. The existing work can only detect aggressive spreaders that scan a large number of distinct destinations in a short period of time. However, stealthy spreaders may perform scanning deliberately at a low rate. We observe that these spreaders can easily evade the detection because current I...

A new micro heat spreader (MHS) concept for efŽ cient transport of large, concentrated heat loads is introduced. The MHS is a single-phase, closed micro uidic system, which utilizes reciprocating ̄ow forced convection. This micro uidic device has the potential to control transient heat loads by active control strategies. Hence, it can be utilized in various thermal management applications, mai...
