Nanoporous Gold Catalysts for Selective Gas-Phase Oxidative Coupling of Methanol at Low Temperature

Methanol Coupling Catalyzed with Gold Gold surfaces can be effective catalysts for partial oxidation reactions, in part because lower interaction strengths of molecules absorbed on gold allow products to desorb before further unwanted oxidations occur. One challenge in these reactions is the low rate of formation of reactive atomic surface oxygen. Wittstock et al. (p. 319; see the Perspective by Christensen and Nørskov) created high–surface area gold catalysts by leaching silver from gold-silver alloys. This material proved to be an effective catalyst for partial oxidative coupling of methanol, yielding methyl formate. Residual silver appears to play a key role in activating the dissociation of molecular oxygen. Leaching of gold-silver alloys creates a highly active catalyst for partial oxidation reactions. Gold (Au) is an interesting catalytic material because of its ability to catalyze reactions, such as partial oxidations, with high selectivities at low temperatures; but limitations arise from the low O2 dissociation probability on Au. This problem can be overcome by using Au nanoparticles supported on suitable oxides which, however, are prone to sintering. Nanoporous Au, prepared by the dealloying of AuAg alloys, is a new catalyst with a stable structure that is active without any support. It catalyzes the selective oxidative coupling of methanol to methyl formate with selectivities above 97% and high turnover frequencies at temperatures below 80°C. Because the overall catalytic characteristics of nanoporous Au are in agreement with studies on Au single crystals, we deduced that the selective surface chemistry of Au is unaltered but that O2 can be readily activated with this material. Residual silver is shown to regulate the availability of reactive oxygen.
Effects of alginate coating incorporated with Bunium persicum essential oil and Lactoperoxidase system on inoculated Listeria monocytogenes in chicken breast fillets

Background: The present study aimed to evaluate the effect of alginate coating incorporated with Bunium persicum essential oil (BPEO) and Lactoperoxidase system (LPOS) individually and in combination to control the growth of inoculated Listeria monocytogenes in fresh chicken breast stored at 4±1°C. Materials and Methods: In vitro antibacterial activity of L. monocytogenes was evaluated using the microdilution method. Chicken breast fillets were inoculated with a cocktail of L. monocytogenes culture, treated with BPEO (0.5 and 1% w/v) and LPOS (5% v/v) as natural antimicrobials, and counted during 20 days of storage at 4±1°C. The data were analyzed in SPSS software (Version 21) through repeated measure ANOVA followed by Bonferroni posthoc tests. P-value less than 0.05 was considered statistically significant. Results: Both individual and combinational use of BPEO and LPOS could significantly inhibit the growth of inoculated L. monocytogenes. However, the combinational use of them had higher effects, compared to control. The results also indicated that the application of alginate coating with no antimicrobial agent significantly supported the growth of inoculated L. monocytogenes on chicken breast samples at 4±1°C. Conclusions: The combinational use of BPEO and LPOS can be practically applied to food systems, especially in the meat industry to ensure the safety of the product.
Functional connectivity predicts changes in attention observed across minutes, days, and months

Significance Sustained attention varies across people and fluctuates over time. Patterns of functional brain connectivity predict a person’s overall sustained attention ability, but do they predict changes in attentional state? Here, across five studies, we show that the same functional connections that predict overall sustained attention ability predict attention changes observed over minutes, days, weeks, and months. Furthermore, these functional connections are sensitive to cognitive and attentional state changes induced by anesthesia. Thus, fluctuations in the same functional connections that predict attention in part reflect fluctuations in attentional state. The ability to sustain attention differs across people and changes within a single person over time. Although recent work has demonstrated that patterns of functional brain connectivity predict individual differences in sustained attention, whether these same patterns capture fluctuations in attention within individuals remains unclear. Here, across five independent studies, we demonstrate that the sustained attention connectome-based predictive model (CPM), a validated model of sustained attention function, generalizes to predict attentional state from data collected across minutes, days, weeks, and months. Furthermore, the sustained attention CPM is sensitive to within-subject state changes induced by propofol as well as sevoflurane, such that individuals show functional connectivity signatures of stronger attentional states when awake than when under deep sedation and light anesthesia. Together, these results demonstrate that fluctuations in attentional state reflect variability in the same functional connectivity patterns that predict individual differences in sustained attention.
Knowledge about HIV/AIDS among B. Sc Nursing Students in Northern Hilly City

Background: A number of studies conducted in different parts of India on HIV/AIDS awareness revealed widespread ignorance and misconceptions about this deadly disease among young people. Methods: This cross sectional was conducted among BSc Nursing students in Shimla city. A purposive sampling technique was used to select the BSc nursing college and 25 nursing students from each study year (1 st to 4 th ) were included. Information regarding their knowledge, regarding HIV/AIDS was obtained using a self-administered, pre-tested, semi-structured questionnaire. Data was analyzed using Epi info v7 software using appropriate statistical tests. Results: Mean age of the participated 100 BSc. Nursing students was 20.26 ± 2.360 years. 13% BSc. Nursing students having very good knowledge, 67% having good knowledge, 19 % had fair knowledge and 1% have poor knowledge about cause, mode of spread, prevention, control and treatment of HIV/AIDS. A statistically significant difference was found among the mean knowledge score between different study years of nursing students. Conclusions: These findings indicate that there is need to further increase the knowledge regarding HIV/AIDS which can be increased by structured teaching programmes and awareness workshops for the nursing students.
Trend of Suicide in Iran During 2009 to 2012: Epidemiological Evidences from National Suicide Registration

Background: Suicide behaviors cause a large portion of Disability adjusted life years worldwide. Objectives: The aim of this research was to study the trend, correlations and discrepancy of registered suicide incidents in Iran from 2009 to 2012 using data from the Iranian suicide registry. Materials and Methods: Suicide registry entries throughout the country between 2009 and 2012, including suicidal attempts and suicides, were collected. Data on age, gender, occupational, marital and residential status along with suicide method, history of previous attempt and history of medical or mental disorders were registered by health service provision staff at the service centers. Geographic mapping and statistical analysis were performed. Results: Amongst the 252911 attempted suicides during the period, we found suicide attempt and suicide rate of 30.5 44.8 and 1.76 2.23 per 100000 individuals, respectively, denoting overall suicide fatality rate of 2.63%. The rate of suicide attempt in different provinces ranged between 0.7 and 271.1 and the rate of suicide between 0.17 and 17.7 per 100000 individuals. Attempted suicides showed more fatality in males, elderly, widow/widowers, divorced and unemployed subjects as well as in residents of rural areas. The most common attempt methods were medication overdose (84%), and the most common suicide methods were hanging (30.3%), medications overdose (28.1%) and self-burning (17.9%); these methods are found at different rates in various parts of the world. Conclusions: While the registry could provide us the most valid data on suicide, the wide range of suicide and suicide attempt rates in different provinces not only could question this statement but also could highlight the importance of studying the ethnic/geographic variations in suicide epidemiology with improved suicide registry and surveillance systems.

Clinical research in HIV-1 infected children

textabstractAcquired immune deficiency syndrome (AIDS) was described for the first time in 1981. Two years later the previously unknown human immunodeficiency virus (HIV) was identified as the causative agent. HIV has been included in the genus Lent/viruses of the Retroviridae family. Two types are recognized: HIV-1 and HIV-2. Of these, HIV-1 is the primary etiologic agent of the current pandemic. HIV probably originates from simian immunodeficiency virus (SIV) which is endemic in African monkey species. Cross species transition may have occurred trough preparation and eating of monkey meat Even today more than one-filth of the monkey meat sold in the markets of Cameroon is infected with SIV. The available evidence suggests that SIV entered the human population from multiple zoonotic infections_ The last common ancestor of the main group of HIV-1 is dated in the first quarter of the twentieth century. Since the eighties of last century a devastating pandemic has developed. At the end of 2003, 40 million people were infected by HIV/AIDS of which 5 million people had been newly infected in that year alone. Ninety-five percent of the new infections occur in the developing countries and 50% in women with child-baring potential. Since mother to child transmission (MTCT) is the main route for transmission of HIV-1 in children, the high number of HIV infected mothers imposes a global health thread to children. Indeed in 2003, 500,000 children died from HIV/AIDS and another 700,000 were newly infected. Besides imposing a direct health risk to children HIV also causes major social and economic dilemmas. HIV mostly affects young adults, killing one or both parents of the children of AIDS victims. Between 10 and 15 million children have become orphans. Hence by destroying human capital and the mechanisms that generate human capital fonmation HIV/AIDS undermines the basis of economic grow1h. If nothing is done to fight the current epidemic HIV-affected countries face economic collapse. In addition, children and families affected by AIDS often face rejection and social isolation.
An evaluation of common risk factors for prolonged grief disorder using the international classification of diseases-11 criteria

Abstract Objectives: Inclusion of Prolonged Grief Disorder (PGD) in the ICD-11 warrants examination of risk factors using diagnostic criteria as there is a paucity of research that has examined risk factors of PGD using the diagnostic criteria. This study examines if the identified risk factors for prolonged grief predict PGD using the diagnostic criteria across three samples. Methods: A cross-sectional survey design was used to assess risk factors and PG-13 in three distinct samples of bereaved adults. The PG-13 was either parsed dichotomously using the ICD-11 diagnostic criteria to indicate presence of PGD or summed to index general grief severity. Results: When using ICD-11 diagnostic criteria, only female gender and high levels of pre-loss contact were identified in separate samples as increasing risk of diagnosis. The most replicable results across samples were found when using the summed PG-13 symptom scores. When using the PG-13 total score, younger age and more pre-loss contact with the deceased were associated with higher symptom levels, which replicated in all three studies. Conclusions : This study provided evidence that the extant literature using summed scores to explore risk factors might not generalize to the ICD-11 diagnostic criteria.
Morphometric study for determining the anteroposterior position of the mental foramen in dentate human subjects

Background: The mental foramen (MnF) is the place where the mental nerve and mental artery exit the body of the mandible, being an important landmark for dentoalveolar surgery. Materials and Methods: For the assessment of MnF topography, we performed a direct morphometric study and two morphometric imaging studies through cone-beam computed tomography (CBCT) scans and orthopantomography (OPG). The following locations of the MnF were investigated: anterior to the first premolar, at the first premolar level, between the two premolars, at the second premolar level, between the second premolar and the 6-year molar, and at the level of the mesial root of the 6-year molar. The data obtained were statistically analyzed by chi-squared test. Results: Through direct morphometry on dentate dry human mandibles, no statistically significant differences were found for the number of MnF located between the two premolars, at the level of the second premolar and between the second premolar and the 6-year molar, depending on age and analyzed side. The number of MnF located between the second premolar and the first molar varies statistically significantly in relation to the subject’s gender but does not vary statistically significantly depending on age and side. By means of imaging morphometry through OPG, we found that the number of MnF located at the first premolar level, between the two premolars, at the second premolar level and between the second premolar and the 6-year molar varies statistically significantly in relation to the age of the patients. Using imaging morphometry trough CBCT scans, we found that the number of MnF located between the two premolars, at the second premolar level and between the second premolar and the 6-year molar varies statistically significantly according to the age of the patients. Comparing the results obtained from the three studies, we found that only according to age the number of MnF located between premolars and at the level of the second premolar varies statistically significantly. Conclusions: Wide and accurate knowledge of both the MnF topography and the key anatomical landmarks used in locating it proves to be essential and clinically relevant in dentoalveolar and endodontic surgery, and for improving anesthesia techniques.
Statistical Study on Cloud Top Heights of Cumulonimbi Thermodynamically Estimated from Objective Analysis Data during the Baiu Season

The level of neutral buoyancy (LNB) around the Japan Islands during the Baiu season in 2001-2005, estimated by lifting a low-level air with the maximum equivalent potential temperature in a vertical direction, is statistically examined from objective analysis data with the horizontal resolution of 20 km, in order to clarify the surrounding atmospheric conditions under which cumulonimbi can form and develop. Three and two peaks are found in the vertical profiles of the appearance rate of the LNB over the sea and on the land, respectively. The high-level (∼ 150 hPa) peak is very weak in June, and the low-level (∼ 900 hPa) peak does not appear on the land. The other peak is found at the middle level (N 700 hPa). The theoretical study shows that the LNB during the Baiu season strongly depends on the lapse rate between the low and middle levels, when the variation of the low-level temperature is within a few degrees. This is because the LNB during the Baiu season rapidly becomes higher as the lapse rate increases. The statistical results show that the lapse rate around the Japan Islands strongly depends on convective activities over upstream regions, especially the southern part of China. Therefore, strong convective activities over the Baiu frontal zone in June produce the middle-level LNB around the Japan Islands to suppress the development of cumulonimbi. In July, the northward shift of the area with strong convective activities considerably releases such suppression, associated with that of the Baiu frontal zone.The middle-level LNB also frequently appears over the other areas around the Baiu frontal zone, although it scarcely appears over the western part of the North Pacific Ocean. Therefore, the middle-level LNB that suggests the existence of cumulonimbi with a cloud top lower than several kilometers is one of the characteristic features around the Baiu frontal zone.

Mental Health Status of Iranian Migrants in Sydney

Objective: The aim of this study was to determine the levels and predictors of psychological distress within the Iranian community in Sydney, Australia. Method: Participants (n = 161) were identified using snowball sampling, and a questionnaire incorporating the General Health Questionnaire (GHQ-20) and other migration-related factors was mailed to their preferred address. Results: A relatively high proportion of respondents (37%) had GHQ-20 scores above the recommended threshold (4+). Students were significantly more likely to report psychological distress compared with respondents who worked full-time. A feeling that migration had contributed to their distress was also found to be significantly associated with above-threshold GHQ-20 scores. Conclusions: Iranian migrants in Sydney may need mental health programs to address migration-related distress.

AIS Electronic Library (AISeL) PERSONALIZED ITEM RANKING FROM IMPLICIT USER FEEDBACK USING HETEROGENEOUS INFORMATION NETWORK FEEDBACK

In this age of information overload, providing useful recommendations to the users of E-commerce websites is an important and challenging problem. Personalized item ranking to recommend top-N items of interest to a user is more challenging in the case of implicit feedback data. Due to the lack of explicit user preferences, a model-based approach like matrix factorization is not effective for implicit user feedback. However, a neighborhood-based technique like Item-based collaborative filtering (IBCF) has shown better performance for implicit user feedback data and is a popular technique due to its scalability property. Although better than matrix factorization based technique for implicit feedback data, IBCF generates low-quality recommendations when data is sparse. In this work, we propose a method to address the problem of IBCF due to the sparseness of data by incorporating the meta-information related to items, and hybridization is done by forming a heterogeneous item information network. The proposed method uses a meta-path based framework for generating personalized item ranking and generates good quality recommendations in real time. The interest of users and popularity of items are leveraged simultaneously to improve the quality of recommendations. To find the intrinsic interest of users from the implicit feedback data, we perform the personalized weight learning to integrate the semantics of various meta-paths in the network. Experimental evaluation of the proposed method using the real-world data shows that the proposed method performs better than IBCF.
