Annual air temperature change characteristics in the Hamedan region of Iran

In this research air temperature characteristics of five meteorological stations located in theHamedan region of Iran were analyzed. The main objective was to identify and assess thepossible climate change of the region during the period 1980 to 2010. To this end, timeseries of the mean annual temperature were investigated using Mann-Kendall andNormalized Residual Mass Curve methods. The climatological stations were Hamedan,Ekbatan Dam, Dargazin, Nojeh and Varayaneh. The results showed that the Mann-Kendalland Normalized Residual Mass Curve tests were similar on detection of the trends. Themean annual temperatures of stations with the exception of Varayaneh and Darghazinshowed significant rapid increasing trends. This study illustrates the identical results of thetwo different tests on climate change identification and more importantly a significantwarming at the majority of stations in the region. These results provide useful informationfor long term planning in water management of the region.
Digital Media Authentication Method for Acoustic Environment Detection

There are many t artifact and different distortions present in the recording. The reflections of sound depend on the geometry of the room and it causes the smearing of the recording called as reverberation. The background noise depends on the unwanted audio source activities present in the evidential recording. For digital media to be considered as proof in a court its authenticity must be verified. A technique proposed is based on spectral subtraction to estimate the amount of reverberation. Also nonlinear filtering based on particle filtering is used to estimate the background noise. Feature extraction is by using MFCC approach. The feature vector is the addition of features from acoustic reverberation and background noise. SVM classifier is used for classification of the environments. Overall system performance is better than previous.
Dust-trapping Rossby vortices in protoplanetary disks

Context. One of the most challenging steps in planet formation theory is the one leading to the formation of planetesimals of kilometre size. A promising scenario involves the existence of vortices able to concentrate a large amount of dust and grains in their centres. Up to now this scenario has mostly been studied in 2D razor thin disks. A 3D study including, simultaneously, the formation and resulting dust concentration of the vortices with vertical settling, is still missing. Aims: The Rossby wave instability self-consistently forms 3D vortices, which have the unique quality of presenting a large-scale vertical velocity in their centre. Here we aim to study how this newly discovered effect can alter the dynamic evolution of the dust. Methods: We performed global 3D simulations of the RWI in a radially and vertically stratified disk using the code MPI-AMRVAC. After the growth phase of the instability, the gas and solid phases are modelled by a bi-fluid approach, where the dust is considered as a fluid without pressure. Both the drag force of the gas on the dust and the back reaction of the dust on the gas are included. Multiple grain sizes from 1 mm to 5 cm are used with a constant density distribution. Results: We obtain in a short timescale a high concentration of the largest grains in the vortices. Indeed, in 3 rotations the dust-to-gas density ratio grows from 10-2 to unity leading to a concentration of mass up to that of Mars in one vortex. The presence of the radial drift is also at the origin of a dust pile-up at the radius of the vortices. Lastly, the vertical velocity of the gas in the vortex causes the sedimentation process to be reversed, the mm size dust is lifted and higher concentrations are obtained in the upper layer than in the midplane. Conclusions: The Rossby wave instability is a promising mechanism for planetesimal formation, and the results presented here can be of particular interest in the context of future observations of protoplanetary disks.
Rectangular ZnO porous nano-plate assembly with excellent acetone sensing performance and catalytic activity

The controlled synthesis of a hierarchically assembled porous rectangular ZnO plate (2.5–3.5 μm length, 1.5–2.5 μm width and 100–150 nm thickness) from bulk ZnO without using any organic substrates, such as solvents/surfactants/structure-directing agents, is presented. The synthesized ZnO plates are single crystalline with exposed (100) facets on the flat surface, porous and formed through the calcination of a hydrozincite [Zn5(CO3)2(OH)6] intermediate. A gas sensor based on the synthesized porous ZnO architecture exhibited high sensitivity towards acetone even in low concentration (S = 3.4 in 1 ppm acetone) with good selectivity. The ZnO nanostructured material as a heterogeneous catalyst also showed excellent catalytic activity for the synthesis of 5-substituted-1H-tetrazoles (yield = 94%). Both the activities are superior than those of other reported ZnO based acetone sensors and heterogeneous catalysts. We believe that the improved properties of the synthesized ZnO nanostructure is due to the exposed (100) facets, and its porous and assembled structure, which provides a reasonably large accessible surface area, and facilitates diffusion and mass transport of gas or substrate molecules.

The Use of Cohesion in Students' Argumentative Writings

This research study aims at discovering the use of cohesion in students’ argumentative writings in terms of its frequency and function. Moreover, it also investigates whether or not there is a correlation between students’ knowledge on cohesion and their writing performances. The participants of the study are seventeen students of English Language and Literature study program at Universitas Pendidikan Indonesia (UPI) who have learned how to compose argumentative writing as well as cohesion. To answer all research questions, this study employs a mixed method research design embracing the characteristics of a case study approach. The data are obtained from students’ argumentative writings, their writing score, and a cohesion test. This research study is grounded by the framework of Cohesion Taxonomy proposed by Halliday and Hasan (1976), which is also a tool for analyzing students’ texts. Results reveal that grammatical cohesive devices—by the use of reference and conjunction as the dominant devices—are slightly more preferable to be used as cohesive resources than the lexical ones. Moreover, it is also found that cohesive devices generally have two major functions which are to remind the readers of the points under discussion and to clarify and affirm semantic relationship between clauses so that the position of the author is clear. In addition, based on the analysis, it is also found that there is no significant correlation between students’ knowledge on cohesion and their writing performances. However, it does not conclusively justify that cohesion is unimportant in writing. Instead, it suggests that writing is a process and cohesion per se is not the determining factor, yet it is one of them. Furthermore, this study recommends that students should expand their repertoire both in vocabulary and sentence structure since the analyzed writings point to their heavy reliance on repetition device.
Optimal Perturbations of an Oceanic Vortex Lens

The stability properties of a vortex lens are studied in the quasi geostrophic (QG) framework using the generalized stability theory. Optimal perturbations are obtained using a tangent linear QG model and its adjoint. Their fine-scale spatial structures are studied in details. Growth rates of optimal perturbations are shown to be extremely sensitive to the time interval of optimization: The most unstable perturbations are found for time intervals of about 3 days, while the growth rates continuously decrease towards the most unstable normal mode, which is reached after about 170 days. The horizontal structure of the optimal perturbations consists of an intense counter-shear spiralling. It is also extremely sensitive to time interval: for short time intervals, the optimal perturbations are made of a broad spectrum of high azimuthal wave numbers. As the time interval increases, only low azimuthal wave numbers are found. The vertical structures of optimal perturbations exhibit strong layering associated with high vertical wave numbers whatever the time interval. However, the latter parameter plays an important role in the width of the vertical spectrum of the perturbation: short time interval perturbations have a narrow vertical spectrum while long time interval perturbations show a broad range of vertical scales. Optimal perturbations were set as initial perturbations of the vortex lens in a fully non linear QG model. It appears that for short time intervals, the perturbations decay after an initial transient growth, while for longer time intervals, the optimal perturbation keeps on growing, quickly leading to a non-linear regime or exciting lower azimuthal modes, consistent with normal mode instability. Very long time intervals simply behave like the most unstable normal mode. The possible impact of optimal perturbations on layering is also discussed.
Using Opinion Mining Techniques for Early Crisis Detection

The goal of our research is to investigate the use of internet monitoring in crisis management using linguistic processing and text mining techniques. We present a system that detects and classifies events on topics and, using an altered opinion mining workflow, detects geographical entities related to these events and the sentiments expressed towards them. The results are displayed in customized GoogleMaps views, indicating areas with a potential risk, such as natural disasters, unfavorable weather or threatening protests. All the processing is done in real time and, depending on the monitored sources, our work could be of used as a population warning system, but it could also be useful for regional or local authorities in managing intervention time and resources by prioritizing the situations for which they have to act.
Facilities Audit in Training Health Care Built Environment

Healthcare organisations have recognised the powerful impact of supply breakdowns and have exploited supply chain management for their quality program, especially regarding lean operations. There are many contributors to poor working environments in the healthcare sector. Some studies relate to inadequate equipment, such as patient lifts and facilities for safe disposal of syringes, needles, and medical waste. However, one area that has so far largely been overlooked relates to the built environment. This study aims to investigate strategic Facilities Management (FM) as a function to support the objectives of providing efficient services to healthcare sector through measuring user satisfaction focusing on public training hospital building. This research involved correlation analysis. The findings show that there is a strong significant relationship among the building performance criteria and the importance of post occupancy evaluation (POE) guidelines in functional and technical performance criteria. Based on the findings, this study proposed the establishment of facilities management and the implementation of systematic annual operation program to ensure that management and services are useful. Secondly, it is intended to establish certain policy instruments such as information tools and economic instruments for hospital management to meet the needs of patients in future hospital development.
Evaluation of a new sampling method for assessing Cladocera richness (Crustacea, Branchiopoda) in macrophyte-rich wetlands

The wetlands found in the Brazilian Cerrado are poorly studied environments regarding ecologi- cal aspects. Assessing the diversity of aquatic invertebrates in wetlands is a challenging task, since there are no standard sampling methods that minimize the spatial effects caused by macrophytes. The aim of this study was to evaluate the efficiency of a new sampling method for assessing Cladocera richness in macrophyte-rich wetlands of Brazilian Cerrado. In six wetlands, one transect was established which corresponded to a gradient of depth or change in aquatic vegetation. Samples containing cladocerans were collected using plankton net dragged among aquatic vegetation in the dry and rainy seasons. The species accumulation curves using non-parametric estimators and the overestimation of richness were used to determine the sampling efficiency. The species accumulation curves showed different asymptotic trends regarding the season and wetland stu- died. Especially in the rainy season, an asymptotic trend was not observed in two of the wetlands studied, which may reflect the influence of seasonality on Cladocera assemblage. Nevertheless, the overestimation of species richness showed that the method of sampling was able to find more than 60% of the estimated species richness, regardless of season or wetland studied. These results indicate that the method employed for sampling Cladocera in the Cerrado wetlands can be considered adequate.

Patterns of stuttering comparing two languages: a case report.

En las personas bilingues, los patrones especificos de la tartamudez en cada una de las lenguas pueden ser diferentes. Este estudio informa sobre el caso de un adulto bilingue espanol/ingles cuyo idioma dominante es el espanol. Pruebas de habla y lenguaje se llevaron a cabo en los dos idiomas. Las muestras seleccionadas para el analisis de corpus de habla fueron: habla espontanea, descripcion de la imagen y lectura. Se encontraron algunas diferencias en la distribucion de la tar­tamudez. De los instantes disfluentes, 61,39 % del total fue presentado en ingles y el otro restante, 38,61 %, en espanol. En ambas lenguas, la tartamudez por tipo de palabra fue mas frecuente en las palabras de funcion (preposiciones, pronombres y conjunciones) que en palabras de contenido (verbos, sustantivos y adjetivos). Para los tipos de disfluencia se observo que fueron similares en espanol e ingles, con el mayor porcentaje en el tipo repeticion de palabras, seguido de prolongacio­nes de fonemas. Estos errores fueron mas frecuentes en ingles que en espanol. Aunque es posible encontrar similitudes en el patron de tartamudeo, es posible sugerir, frente a las leyes generales para la disfluencia en bilingues, que las diferencias pueden asociarse, no solo con la idiosincrasia especifica del idioma, sino tambien con las caracteristicas del bilinguismo propio de la persona.
PENTAGAMAVUNON-0 TERHADAP PENGHAMBATAN EKSPRESI SIKLOOKSIGENASE-2 PADA MODEL KANKER KOLON TIKUS WISTAR Effectiveness of Pentagamavunon-0 on The Inhibition of Cyclooxygenase-2 Expression in Wistar Rats Colon Cancer Model

The aim of the study is to determine the effectiveness of pentagamavunon-0 (PGV-0) on the inhibition of cyclooxygenase-2 (COX-2) expression in Wistar rats with colon cancer. Twenty male Wistar rats were randomly divided into 4 groups of five. Group I was negative control and group II was positive control. Groups III and IV were given PGV-0 40 mg/kg BW for 15 and 25 week’s respectively. Oral administration of PGV-0 was given twice a week. 1,2-dimethylhydrazine.2HCl (DMH) was subcutaneously injected, once a week for 15 weeks. All animals were sacrificed at week 26, colon was fixed in 10% buffer formalin for gross and microscopic examination. Scoring of COX-2 expression was carried out using Duke’s stage method and immunoreactivity score (IRS). The results showed that PGV-0 given for 25 weeks was reduced the number of nodules from 5 to 2 nodules (60%); the area of colon cancer (length x width) from 0.712 to 0.0043 mm (99.31%). PGV-0 given for 15 weeks was only 10% reduced the number of nodules and the area of colon cancer from 0.712 to 0.0062 mm (99.07%). Immunoreactivity score of COX-2 that was expressed in group III was 4, and in group IV was 5. Histological features of colonic cancer support the results mentioned above. To conclude, the administration of PGV-0 40 mg/kg BW reduced the number and area of tumor nodules, possibly through the inhibition of COX-2 expression. ____________________________________________________________________________________________________________________
Racialized Space and the Culture of Segregation: Hewing a Stone of Hope from a Mountain of Despair

I intend this writing to be consistent with Iris Young's admonition that social description and explanation should be critical-that is, "aim to evaluate the given in normative terms. Without such a critical stance, many questions about what occurs in society and why, who benefits and who is harmed, will not be asked, and social theory is liable to reaffirm and reify the given social reality.

High efficiency n-type Si solar cells on Al2O3-passivated boron emitters

In order to utilize the full potential of solar cells fabricated on n-type silicon, it is necessary to achieve an excellent passivation on B-doped emitters. Experimental studies on test structures and theoretical considerations have shown that a negatively charged dielectric layer would be ideally suited for this purpose. Thus, in this work the negative-charge dielectric Al2O3 was applied as surface passivation layer on high-efficiency n-type silicon solar cells. With this front surface passivation layer, a confirmed conversion efficiency of 23.2% was achieved. For the open-circuit voltage Voc of 703.6mV, the upper limit for the emitter saturation current density J0e, including the metalized area, has been evaluated to be 29fA∕cm2. This clearly shows that an excellent passivation of highly doped p-type c-Si can be obtained at the device level by applying Al2O3.
High Voltage Multilevel DC-DC Converter in Auto Balancing Mode

In this paper balancing theory of a three level DC-DC converter is presented. It is proposed to make dc link voltages balanced across the capacitor stack. This voltage distribution gets equally distributed by selecting the appropriate switching frequency. This work is to investigate the new control scheme to incorporate the current adaptive switching in DC-DC converters. The major advantage of this novel scheme is to develop the bi-directional high voltage multilevel converters required in many high power industrial applications. A systematic approach and mathematical study is presented. Simulation results validates this proposed scheme.
THE EFFECT OF TRANSCRANIAL DIRECT CURRENT STIMULATION ON ANXIETY DURING TREATMENT OF OPIATE ADDICTION VIA ULTRA RAPID OPIOID DETOXIFICATION UNDER ANESTHESIA

Aims and background: Opiate addiction, is one of the most prominent health problem in diverse communities which may lead to anxiety during treatment and relapse. This study investigates the efficacy of transcranial direct current stimulation (TDCS) on anxiety during treatment of opiate addiction via the ultra rapid opioid detoxification approach (UROD). Methods and materials: It is a randomized, double blind controlled survey which was conducted on forty scheduled subjects for UROD. TDCS was applied at 24 hour intervals for two sessions by the researcher. The anxiety scores were recorded before the intervention, immediately before UROD, and 24 hours afterwards using Beck questionnaire. Data were analyzed via repeated measure ANOVA using SPSS software. Findings: All the participants were male with mean drug abuse duration of 8.37 ±2.4 and 7.37 ± 2.4 years in intervention and control groups, respectively. According to statistical analysis, anxiety was less in the intervention group and the difference was significant at all time intervals (P-value≤0.008). We observed about 90% decline for anxiety in intervention group one hour after UROD (p-value≤ 0.01) while it was about 25%for control group (P-value=0.163) and it increased in the control group within 24 hours. conclusions: Generally speaking, TDCS is an effective approach to alleviate anxiety due to pre-anesthesia and withdrawal syndromes during UROD.
