Introduction: Students in elementary schools due to the physical and behavioral characteristics more than adults have exposed to environmental hazards. This study was conducted to examine the environmental health and safety indices in girls' elementary schools in Ilam city. Materials and methods: This cross-sectional study was carried out via census sampling method in girls' elementary schools...

An undesirable way, which a cryptographic An undesirable way, which a cryptographic module exchanges some information with its module exchanges some information with its neighborhood in. neighborhood in.

the zagreb indices are the oldest graph invariants used in mathematical chemistry to predictthe chemical phenomena. in this paper we define the multiple versions of zagreb indicesbased on degrees of vertices in a given graph and then we compute the first and secondextremal graphs for them.

In some companies, undesirable costs are imposed for provision of services. It is required that current outputs of decision making units are produced at minimal undesirable cost. In this paper, a new method is proposed for evaluating the undesirable cost imposed on the units. Moreover, data is considered in fuzzy number form, due to the observed input-output data are sometimes imprecise in real...

BACKGROUND Injuries are a major cause of mortality and disability worldwide and are estimated to become the third leading cause of death by 2020. Most traffic deaths occur during the prehospital phase; consequently, prehospital trauma care has received considerable attention during the past decade. However, there is no study on the prehospital immobilization of spine and limbs in patients with ...

Standard approaches for detecting malicious behaviors, e.g. monitoring network traffic, cannot address process-related threats in SCADA(Supervisory Control And Data Acquisition) systems. These threats take place when an attacker gains user access rights and performs actions which look legitimate, but which can disrupt the industrial process. We believe that it is possible to detect such behavio...

Undesirable outputs are often produced together with desirable. This joint production of good and bad outputs bring about a difficulty for productivity measurement. Here we introduce a directional distance function and use it as a component in a new productivity index. This index, as an empirical example shows, seems to solve the problem caused by the joint production of good and bad outputs. P...

Motivated by our ongoing efforts in the development of Refraction 2, a puzzle game targeting mathematics education, we realized that the quality of a puzzle is critically sensitive to the presence of alternative solutions with undesirable properties. Where, in our game, we seek a way to automatically synthesize puzzles that can only be solved if the player demonstrates specific concepts, concer...

Phytate (myo-inositol (1, 2, 3, 4, 5, 6) hexakisphosphate), a naturally compound formed during maturation of plant seeds and grains is a common constituent of plant-derived foods. The major concern about the presence of phytate in the diet is its negative effect on mineral uptake. Minerals of concern in this regard would include Zn 2+, Fe 2+/3+, Ca 2+, Mg 2+, Mn 2+, and Cu 2+. Especially zinc a...
