“Love” Phenomenon and Neurobiology of Love Relations
Ali Evren Tufan,rem Yalu
Psikiyatride Guncel Yaklasimlar , 2010,
Abstract: The biology; especially the neurobiological features of the “love” phenomenon has recently started to attract attention. Love relations and attachment, which is closely related with them, are known to be important in health and disease. Love and love relations are found to be complex neurobiological phenomena based on activation of the limbic system of the brain. Those processes involve oxytocin, vasopressin, dopamine and serotonergic functions. Additionally, endorphine and endogenous opiate systems as well as nitrous oxide play role in those processes. The stages of love and love relations may demonstrate different neurochemical and neurophysiological features and may partially overlap with m aternal, romantic and sexual love and attachments. The aim of this article is to evaluate the common neurobiological pathways underlying the “love” phenomenon as well as their importance in medicine and health.

Abstract: Objective: Migraine is a recurrent primary headache disorder characterized by different clinical presentations. Migraneurs report excessive sensitivity to light, sound, motion, odours, and other sensory stimuli in and between acute migraine attacks. This study was undertaken to document different trigger factors and to evaluate the differences in episodic and chronic migraine forms. Headache trigger factors were questioned in 190 patients.Methods: Headache triggering factors were questioned in 190 patients. A set of questions concerning the trigger factors were prepared and the information about the triggering factors was collected by a structured interview. All the patients were administered Beck Depression Inventory (BDI). All analyses in this study were performed by NCSS 2007 packet programme.Results: The trigger factors reported in this study were stressor factors, noise, sleep disturbances, fatigue, hunger, physical effort, light, sun, cold, factors affecting scalp, traveling by motor vehicle, eye strain, crowd , odours, crying, weather, high blood pressure, cigarette smoke and menstruation respectively. Conclusion: The prophylactic treatment of migraine decreases the frequency of headaches by affecting various factors. Understanding the link between the trigger factors and headache may yield novel preventative and therapeutic approaches in the management of headache. (Archives of Neuropsychiatry 2010; 47: 58-63)
MicrobMatcher: a microbial comparison software based on matrix-assisted laser desorption/ionization with time-of-flight mass spectrometry  [PDF]
Feng Liu, Yizhen Fu, Yalu Ye
Journal of Biomedical Science and Engineering (JBiSE) , 2011, DOI: 10.4236/jbise.2011.45051
Abstract: Matrix-assisted Laser Desorption/Ionization with Time-of-flight Mass Spectrometry (MALDI-TOFMS) was investigated as a method for the rapid identifica-tion of species. Current demand in microbial identi-fication is how to compare unknown strains to the known one quickly, semi-automatically and accurately. In this paper, we present a software tool that allows flexibly microbial matching in a user-friendly way, by letting the users to customize comparison parameters including: in vitro transcription enzyme, mass tolerance,minimum fragment length, intensity threshold and corresponding weights. We provide three spectral scoring functions to compute the affin-ity between the species. Therefore, the precision of microbial comparison increases. To test and verify this tool, we employed experimental spectral data based on MALDI-TOFMS and the gene sequences of E.coli and Salmonella. This software is written in Java for cross-platform intention.
Recycling of End of Life Concrete Fines into Hardened Cement and Clean Sand  [PDF]
Somayeh Lotfi, Peter Rem
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76083
Abstract:

One of the massive by-products of concrete to concrete recycling is the crushed concrete fines, that is often 0 - 4mm. Although the construction sector is to some extent familiar with the utilization of the recycled coarse fraction (>4 mm), at present there is no high-quality application for fines due to its moisturized and contaminated nature. Here we present an effective recycling process on lab scale to separate the cementitious powder from the sandy part in the crushed concrete fines and deliver attractive products with the minimum amount of contaminants. For this study, a lab scale Heating-Air classification system was designed and constructed. A combination of heat and air classification, resulted in a proper separation of finer fraction (0 - 0.250 mm), from coarser fractions. Heating of the materials was followed by ball milling to enhance the liberation of the cementitious fraction. Experiments were carried out at different heating temperatures and milling durations. Experimental results show that by heating the materials to 500 for 30 seconds, the required time of ball milling is diminished by a factor of three and the quality of the recycling products satisfies well the market demand. In addition, the removal of contaminants is complete at 500. The amount of CaO in the recovered finer fraction from the recycling process is comparable with the amount of CaO in low-quality limestone. By using this fraction in the cement kiln as the replacement of limestone, the release of the chemically bound CO2 could be reduced by a factor of three.

A Robust Indicator for Promoting Circular Economy through Recycling  [PDF]
Francesco Di Maio, Peter Carlo Rem
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.610096
Abstract: In order to move towards a more sustainable development, it is necessary not only to minimize the use of materials in the design stage and to find new materials as alternatives to nonrenewable ones (e.g. optical fiber instead of copper, biopolymers instead of polymers from oil) but also to reclaim as much as possible material value through effective recycling. To this extent, recycling can play a key role in multiple dimensions, while providing new business opportunities for innovative companies, having positive impacts on the society and the environment and fostering an effective circular economy as well. Because of the advanced waste management infrastructures available in developed countries, it is possible to achieve an almost complete collection of solid wastes into a variety of controlled bulk material flows. However, the picture for the follow-up step, the recycling of raw materials such as steel, non-ferrous metals, polymers and glass from these flows, is less positive. Materials value recovered from waste represents a very small fraction of European GDP. The fundamental issue is that policymakers still lack an effective key performance indicator for stimulating the recycling industry. Therefore although recycling plays an important role in the circular economy perspective, it is necessary to radically change the metric used so far to compute the recycling rate. Nowadays, the recycling rate is computed measuring the amount of material entering the recycling facilities. This approach has brought about an inaccurate and somehow misleading indicator (the recycling rate) which contributed to wrong decision making and to poor innovation in the industry. The new approach proposed in this paper considers the use of a Circular Economy Index (CEI) as the ratio of the material value produced by the recycler (market value) by the intrinsic material value1 entering the recycling facility. It is argued that this index is related to strategic, economic and environmental aspects of recycling and it has very important implications as decision making tool. To compute the CEI it is necessary to know detailed information of the components and materials contained in each end of life (EOL) product entering the recycling facilities and how they end up in the recycled raw materials. Therefore an accurate accounting of materials (with standards if available), mass, chemical composition and smallest dimension (e.g. a screw, a plastic foil) is proposed.
An Imputation Approach for Oligonucleotide Microarrays

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0058677
Abstract: Oligonucleotide microarrays are commonly adopted for detecting and qualifying the abundance of molecules in biological samples. Analysis of microarray data starts with recording and interpreting hybridization signals from CEL images. However, many CEL images may be blemished by noises from various sources, observed as “bright spots”, “dark clouds”, and “shadowy circles”, etc. It is crucial that these image defects are correctly identified and properly processed. Existing approaches mainly focus on detecting defect areas and removing affected intensities. In this article, we propose to use a mixed effect model for imputing the affected intensities. The proposed imputation procedure is a single-array-based approach which does not require any biological replicate or between-array normalization. We further examine its performance by using Affymetrix high-density SNP arrays. The results show that this imputation procedure significantly reduces genotyping error rates. We also discuss the necessary adjustments for its potential extension to other oligonucleotide microarrays, such as gene expression profiling. The R source code for the implementation of approach is freely available upon request.
