Authors: Shahpari Abdolrasoul , Aminsharei Farham , Ghashang Majid 
Published: April 2019

Introduction: Today, due to the discussion of carbon management as well as the reduction of greenhouse gases and national and international commit-ments involved in this regard such as the Six Development Plan (2016-2020) and climate change convention it, is necessary to calculate and manage all industrial processes that lead to the greenhouse gases emission. Methane is the main ingredient of natural gas, which its potential for global warming is 25 times more than carbon dioxide. Approximately a third of these emissions are in the different sections of oil production and processing, transferring and storing of natural gas.

Materials and methods: The present study has been done to calculate the amount of methane emission to the atmosphere by startup of Siemens gas compressors in Iran gas transmission operation district 2. In this study, op-erational information of 25 Siemens gas Turbo compressors related to six gas transmission stations collected and with modeling conditions in PHAST, the amount of methane emission has been determined.

Results: According to the obtained data, in 2018 this district has released 140/870 tons of methane gas to the atmosphere due to the above-mentioned process. The methane emission factor for Type C compressor is 241/15 kg, for type D compressor is 341/35 kg and this factor for type E compressor is 375/48 kg.

Conclusion: The release rate obtained for each type of the C, D and E com-pressors can be used to calculate the emissions of all SIEMENS 10MV2A gas compressors of the same model in Iran.

Authors: Hassan Elham Mobarak , Fatahi Ebrahim , Khan Mahnaz Karim , Noori Faezeh 
Published: April 2019

Introduction: Dust is a natural process in desert areas, which is caused by the effect of strong winds on the surface of the soil. The aim of this study is to investigate the conditions of the formation and expanding the dust storm formed in Iraq to the Khuzestan province in February, 2017.

Materials and methods: The synoptic analysis was conducted using meteo-rological parameters from ERA-interim and observation data from the Ahwaz station. In addition, the EUMETSAT image, the DREAM and the HYSPLIT model output were used.

Results: As the results show, regarding to the storm, dust in low- pressure area located over Iran is expanded toward the west associated with the tough 500 hPa . With the formation of the high-pressure area in Syria, a pressure gradient is formed in Iraq resulting the northwest wind with the wind speed of 28 knots s (14 m/s) in 925 hPa. These conditions have led to transport the dust from Iraq toward southwest of Iran. A jet stream is formed 12 h before entering the dust from Iraq to Iran, at 900 hPa. The HYSPLIT model predicts the particle’s motion along the northwest winds, and is matched with the wind field in synoptic structure.

Conclusion: According to this study, the most important factors in dust trans-port to the Persian Gulf are geographic location of the low- and high-pressure area and the formed northwest winds in Iraq.
A Procedure for Liquid-Assisted Gas Lift Unloading Using a Transient Flow Simulator
Authors: Coutinho Renato P. , Waltrich Paulo J. 
Published: April 2019

Summary
In this paper we describe using a commercial transient multiphase-flow simulator to develop a new operational procedure for liquid-assisted gas lift (LAGL) unloading. The simulation model is used in our study to perform sensitivity analysis on the controlling parameters for the LAGL unloading operation.
This simulation model is validated with experimental data from field-scale test data presented by Coutinho et al. (2018). From the simulation results and experimental data, it is possible to demonstrate how the injection of a gas/liquid mixture can significantly decrease the injection pressure for unloading operations. Different combinations of injection gas/liquid ratio are numerically tested to evaluate the effect of gas/liquid ratio on the injection pressure during the complete unloading operation.
The validated model was used with a newly developed procedure for the complete unloading operation. The modeling results show that using the LAGL technique enabled us to reduce the injection pressure from 1,200 psig, when using single-phase gas in a single-point injection system, to approximately 700 psig, when injecting gas/liquid mixtures in a single-point injection system. Analyses on the effect of gas lift valve-orifice size, also presented here, show that using large orifice sizes might reduce the effect of flow friction through the gas lift valve, which directly affects the efficiency of the LAGL unloading operations.
Hydrological alteration of the upper Yangtze River and its possible links with large-scale climate indices
Authors: Dong Qianjin , Fang Debin , Zuo Jian , Wang Yongqiang 
Published: April 2019

Abstract
The relationship between hydrological alteration and climate variability in the upper Yangtze River is not fully understood. In this paper, the periodicity features and the intercorrelation of annual and seasonal eco-flow metrics at the Yichang gauge station are analyzed for the period 1882 to 2013. Analysis is carried out to explore the formation of the eco-flow metrics and the possible linkages between eco-flow metrics and selected climate indices, using the cross-wavelet and wavelet coherence methods on data from 1948 to 2013. The results show that the variation of eco-flow metrics correlates well with some selected climate indices, but changes in different eco-flow metrics are complex. Most annual and seasonal eco-flow metrics correlate well with the Northern Hemisphere (N.H) and Indian Ocean Dipole (IOD) and have a significant common power in the two to four years band. In addition, most annual eco-flow metrics have an obvious phase relationship with the selected climate indices. However, the seasonal eco-flow metrics have no significant phase relationship with the selected climate indices. These findings provide a better understanding of how hydrological alterations of the streamflow and better water resource management can ensure ecosystem sustainability for the Yangtze River.
Biodegradation of ametryn and dicamba in a sequential anaerobic-aerobic batch reactor: A case study
Authors: Mahesh Gajanuru Basappa , Manu Basavaraju 
Published: April 2019

AbstractAgricultural runoff often contains persistent halogenated herbicide compounds like 2-(ethylamino)-4-(isopropylamino)-6-(methylthio)-s-triazine (ametryn) and 3,6-dichloro-2-methoxybenzoic acid (dicamba). These can enter the food chain through drinking water, causing serious effects for people and the environment. A sequential anaerobic reactor followed by an aerobic reactor was operated and investigated for herbicide removal efficiency at constant, three-day, hydraulic retention time (HRT) and organic loading rate (OLR) of 0.2025 kg-COD/m3/d. The effect of the herbicides on anaerobic bacteria was evaluated based on total biogas production and bacterial activity, which indicated that there was no inhibition on the acclimated biomass. The sequential reactor pair removed 72% of ametryn and 78% dicamba, with COD removal efficiencies of 86% and 85% respectively. The different high-performance liquid chromatography (HPLC) peaks indicate that the compounds are biotransformed and this was confirmed by gas chromatograph high resolution mass spectrometry (GC-HRMS).
Enhanced visible light photocatalytic activity of AgI/TiO2 composite fabricated by a grinding method
Authors: Xu Jin , Gao Dasheng , Cui Shuang , Wang Xiaohua , Liu Ningning 
Published: April 2019

Abstract
Through a simple grinding method, AgI/TiO2 composites were successfully synthesized. The as-prepared AgI/TiO2 composites were used as photocatalysts for Rhodamine B (RhB) degradation under visible light irradiation and exhibited excellent photocatalytic performance. In the presence of composites, almost 100% RhB was decomposed after 60 min. The photocatalytic activity of AgI/TiO2-0.5 composite was optimal, which was 9.5 times higher than that of pristine TiO2, and 15.6 times higher than that of AgI. Moreover, experimental results revealed that the improved photocatalytic activity was not only ascribed to the loading AgI but also resulted from the method that enabled the exposure of more active sites in the composites. In addition, the intimate interfacial contact obtained by this method could also promote the efficient separation of photogenerated electron-hole pairs. Moreover, the possible photocatalytic active species and the stability of the photocatalyst were investigated in detail.

Published: April 2019

Este trabajo tiene por objetivo analizar las opiniones de los habitantes de las comunidades de estudio acerca del posible desarrollo de la minería en su región y las percepciones sobre este tema. Para ello se elaboró un estudio descriptivo de corte transversal, bajo una metodología de variables cualitativas y cuantitativas; adicionalmente se emplearon fuentes primarias, con instrumentos como encuestas y entrevistas, para obtener datos socioeconómicos de las familias, las opiniones de estas y la perspectiva de la población frente a los proyectos de explotación minera de oro y sus posibles impactos, las estrategias de lucha de las comunidades y las estrategias diseñadas por las empresas mineras. Se encontró que la mayoría de la población en as comunidades de Santa María de Zotoltepec, Tuligtic, La Cañada y Tetela de Ocampo Centro rechaza la minería a cielo abierto y su percepción es negativa acerca de los impactos que tendría la explotación minera; además, se siente vulnerable frente a los proyectos mineros y al gobierno.
Turismo cultural y peregrino. Producciones de pasado en Real de Catorce
Authors: Álvarez Irene 
Published: April 2019

El artículo se propone contrastar las nociones de patrimonio movilizadas por agencias federales dedicadas a la protección y promoción de centros históricos con las concepciones en torno al valor generadas por actores locales en el marco de una peregrinación religiosa. Comprender el patrimonio como producción del valor, y no como una cualidad intrínseca de los objetos, permite analizar una peregrinación religiosa como una práctica patrimonial, en tanto que vincula a los habitantes y visitantes del santuario con sus ancestros. Del análisis de los resultados del trabajo etnográfico se concluye que la peregrinación católica al santuario de Real de Catorce, en San Luis Potosí, México, es una forma de preservar el vínculo con un territorio que tiene una fuerte tradición migratoria. La investigación ofrece una aproximación analítica novedosa al estudio del turismo peregrino y el turismo cultural a través de fuentes primarias.

Published: April 2019

:The identification of Drug-Target Interactions (DTIs) is an important process in drug discovery and medical research. However, the tradition experimental methods for DTIs identification are still time consuming, extremely expensive and challenging. In the past ten years, various computational methods have been developed to identify potential DTIs. In this paper, the identification methods of DTIs are summarized. What's more, several state-of-the-art computational methods are mainly introduced, containing network-based method and machine learning-based method. In particular, for machine learning-based methods, including the supervised and semisupervised models, have essential differences in the approach of negative samples. Although these effective computational models in identification of DTIs have achieved significant improvements, network-based and machine learning-based methods have their disadvantages, respectively. These computational methods are evaluated on four benchmark data sets via values of Area Under the Precision Recall curve (AUPR).

Background:Immunity is the ultimate barrier between foreign stimuli and a host cell. Unwanted immune responses can threaten the host cells and may eventually damage a vital organ. Overproduction of inflammatory cytokines may also lead to autoimmune diseases. Inflammatory cells and pro-inflammatory cytokines can eventually progress to renal, cardiac, brain, hepatic, pancreatic and ocular inflammation that can result in severe damage in the long run. Evidence also suggests that inflammation may lead to atherosclerosis, Alzheimer’s, hypertension, stroke, cysts and cancers.Methods:This study was designed to correlate the possible molecular mechanisms for inflammatory diseases and prevent biochemical changes owing to inflammatory cytokines by using Resveratrol. Therefore, we searched and accumulated very recent literature on inflammatory disorders and Resveratrol. We scoured PubMed, Scopus, Science Direct, PLoS One and Google Scholar to gather papers and related information.Results:Reports show that inflammatory diseases are very complex, as multiple cascade systems are involved; therefore, they are quite difficult to cure. However, our literature search also correlates some possible molecular interactions by which inflammation can be prevented. We noticed that Resveratrol is a potent lead component and has multiple activities against harmful inflammatory cytokines and related microRNA. Our study also suggests that the anti-inflammatory properties of Resveratrol have been highly studied on animal models, cell lines and human subjects and proven to be very effective in reducing inflammatory cell production and pro-inflammatory cytokine accumulation. Our tables and figures also demonstrate recent findings and possible preventive activities to minimize inflammatory diseases.Conclusion:This study would outline the role of harmful inflammatory cytokines as well as how they accelerate pathophysiology and progress to an inflammatory disorder. Therefore, this study might show a potential therapeutic value of using Resveratrol by health professionals in preventing inflammatory disorders.
Therapeutic Effect of Novel Antidepressant Drugs Acting at Specific Receptors of Neurotransmitters and Neuropeptides
Authors: Werner Felix-Martin , Coveñas Rafael 
Published: April 2019

Background:
Major depression is a frequent psychiatric disease. One- third of the depressive patients
remain treatment-resistant; thus, it is urgent to find novel antidepressant drugs.

Objective:
In major depression, in several brain areas the neural networks involved and the alterations of neurotransmitters
and neuropeptides are updated. According to these networks, new pharmacological agents and effective
combinations of antidepressant drugs achieving a more efficacious antidepressant treatment are suggested.

Results:
In the neural networks, the prefrontal cortex has been included. In this brain area, glutamatergic neurons,
which receive an activating potential from D2 dopaminergic neurons, presynaptically inhibit M1 muscarinic cholinergic
neurons via NMDA receptors. Medium spiny GABAergic/somatostatin neurons, which receive projections
from M1 muscarinic cholinergic neurons, presynaptically inhibit D2 dopaminergic neurons via
GABAA/somatostatin1 receptors. The combination of an NMDA receptor antagonist with an M1 muscarinic cholinergic
receptor antagonist can achive a rapid, long-lasting antidepressant effect.

Conclusion:
In preclinical studies, the antidepressant effect of orvepitant, an NK1 receptor antagonist, has been
demonstrated: this antagonist reaches a complete blockade of NK1 receptors. In clinical studies, the combination
of an NMDA receptor antagonist with an M1 muscarinic cholinergic receptor antagonist should be investigated indepth
as well as the therapeutic effect of orvepitant. In clinical studies, the antidepressant effect of a triple reuptake
inhibitor should be examined and compared to current antidepressant drugs.
