The consumption of different forms of plastics is interesting to the environmental protection subject. The increasing use of plastics in many areas of human daily life results in the accumulation of plastic waste in the environment. The introduction of plastic waste in concrete is a solution to preserve the environment and reduce the cost of concrete. This paper presents an overview of some published research regarding the use of waste plastic in concrete. we present the work of many researchers on the valorization of plastic waste in concrete in different forms as a partial replacement of fine and coarse aggregate as well as fibers and their effects of waste plastic addition on the fresh, mechanical, and durability of concrete. The research work seems interesting, which shows the possibility of recycling plastic waste in concrete. However, it will be interesting to explore the combined uses of plastic as aggregate and fiber in concrete, which allows a possible recovery of additional quantities of plastic waste in concrete., (undefined)

* Corresponding author. e-mail: Dadkhah80@gmail.com. Sanjay A Pai discussed an important problem in the academic world and warns researchers about predatory publishers [1]. Devnani and his colleagues believe that low-income countries must devote more resources and more researcher support to aid in dealing with predatory journals [2]. According to these Authors, predatory journals are not indexed journals or, at least, they lack reputable indexes (such as “PubMed” [3]). These Journals declare, e.g. We have contacted you earlier through email. Since we have not received any response from you regarding your valuable manuscript submission, we are taking the liberty of resending the invitation as we are aware that you may be engaged in other activities or my message may not have successfully reached you. I request you to submit a Research, Review, Case report or a Short commentary for December Issue. The impact factor of the journal is 1.9*. What’s that*? Nothing. It is written in the e-mail you have received, but if you go to their websites, you see that the declared IF is "an unofficial" IF. A fake Impact Factor, one of the stringent criteria to define a predatory journal by Beall Jeffrey [4]: it uses some made up measures, so claiming an exaggerated international standing. We are now observing that predatory practices are also emerging among some reputable, indexed journals. Some Scopus, PubMed and Thomson Reuters indexed journals (especially journals indexed in Thomson Reuters' Zoological Index) seem to act like predatory journals, e.g., having unclear review processes and hidden publication fees. In effect, reviewing the last updates in Beall’s list of predatory journals, we can find such journals [5]. It can undermine the credibility of research results and damage public trust in biological/medical journals. In particular, we have observed questionable “special issues” in reputable indexed journals, as an example of these predatory practices [6]. It seems that some reputable indexed journals create special issues and publish many papers outside of the journal’s scope apparently only to make money. Some open access journals which do not have a publication fee and have been supported by Universities or Institutes create these questionable “special issues” and publish many papers only to generate revenue. Figure 1 shows the number of published papers in questionable special issues by some reputable, indexed journals in the first half of 2015.

Condition monitoring systems of machining processes are essential technology for improving productivity and automation. Tool wear monitoring of cutting tools is one of the important applications in this area. In this paper, the effect of collet fixturing quality on the design of condition monitoring systems to detect tool wear is discussed. The paper investigates the difference in the system's behaviour and the changes in the condition monitoring system when the cutting tool is not rigidly fastened to the collet. A group of sensors, namely acoustic emission, force, strain, vibration and sound, are used to design the condition monitoring system. Automated Sensor and Signal Processing Selection (ASPS) approach1 is implemented to address the effect of the tool holding device (collet) on the monitoring system and the most sensitive sensors and signal processing method to detect tool wear. The results prove that the change in the fixturing quality could have significant effect on the design of the condition monitoring system and the behaviour of the system.

Türker, Dilek (Balikesir Author), Anilocra physodes (Linnaeus, 1758) (Isopoda, Cymothoidae) is reported for the first time on Phycis blennoides (Brünnich, 1768) (Pisces; Phycidae) from the North Aegean Sea Coasts of Turkey. The present paper aims to present the morphological characters of Anilocra physodes from Turkey. Some morphological characters of this parasitic isopod are illustrated. A new host species for Anilocra physod

Propolis is a gum-like product gathered by bees from various plants. It is known that the propolis has anti-bacterial, anticarcinogenic, and immune-stimulating biological activities. In the present study, we have investigated the anti-microbial activity of propolis against certain important human microbes. The paper disc diffusion method was used to investigate the propolis activity and the inhibition zones were measured. Results revealed that the ethanolic and water extracts of propolis have a strong inhibitory potential against Aspergillus brasiliensis Varga and Escherichia coli Migula strain (ATCC 0157:H7) regardless of the time of propolis harvesting. The propolis ethanolic and water extracts were ineffective against Escherichia coli strain (ATCC 29522) and Proteus mirabilis Hauser. Jordan propolis was the most effective in inhibiting the Enterobacter aerogenes 35029 Hormaeche and Edwards than the Chinese, Turkish and Tablet propolis samples. Furthermore, the Jordan propolis and the Chinese crude 2 propolis were the most effective against the Candida albicans mold. The Chinese propolis was the most effective against A. brasiliensis mold.
