Published: December 2017

В работе представлены результаты конечно-элементного моделирования остаточного напряженно-деформированного состояния (НДС) в полосе размерами 600×60×4 мм из стали 08пс после тепловой правки прогиба её оси, обусловленного нагревом одной из ее продольных кромок движущейся вольфрамовой сварочной дугой в аргоне (TIG-процесс сварки). Тепловая правка осуществлялась двумя последовательными нагревами второй кромки полосы по той же технологии, что и нагрев первой кромки. Оба нагрева второй кромки с целью тепловой правки прогиба проводились после формирования в ней остаточного НДС от предшествующей технологической операции. Анализ расчетного остаточного НДС в полосе осуществлялся по истечении 20 минут от начала предшествующего нагрева полосы. Режим нагрева обеих кромок полосы одинаковый с погонной энергией нагрева 120 Дж/мм. После нагрева первой кромки прогиб оси полосы в среднем поперечном сечении составляет 1,393 мм, продольное укорочение по осевой линии ~0,216 мм. После первого нагрева второй кромки с целью правки указанного выше прогиба его величина в остаточном состоянии уменьшилась до 0,761 мм (на 45,37%), укорочение увеличилось до 0,300 мм (на 38,89%). После второго нагрева второй кромки с целью дальнейшего уменьшения прогиба его величина стала равной 0,219 мм (общее уменьшение на 84,28%), укорочение полосы по оси увеличилось до 0,357 мм (увеличение от минимального на 65,28%).

Authors: Gauli Sirisa , Shrestha Gauri
Published: December 2017

Background: There has been considerable increase in elderly population all over the world and this population is thought to be at a greater risk of depression which is a major health problem. Comparatively, depression is found to be at a higher rate among women compared to men.Objective: This study aims to identify the factors influencing the level of depression among elderly women residing in old age home of Devghat, Tanahu.Materials and Methods: This study is entirely based on primary data taking a total population (116) of elderly women from face to face interview using the short version of Geriatric Depression Scale (GDS), Instrumental Activities of Daily Living Scale (IADL) and socio-demographic interview schedule. To gather information, mobile data collection tool i.e. GIS Cloud was used. Data was analyzed using descriptive and inferential statistical methods. To determine the significant factors influencing depression among the respondents, multinomial logistic regression model was used.Results: The mean score obtained from GDS was 7.52 ranging from 2 to 14. About 24% of the respondents had mild depression and 47% of them had severe depression. More than 66% of them were from rural area. About 50% of respondents had no financial support; about 53% of them were found with feeling of loneliness. Regression analysis showed that the factors like age at marriage, type of place of previous residence, financial support, satisfaction of living condition, feeling of loneliness, and IADL score were found to be significantly associated with level of depression.Conclusion: The result of the study indicates that most of the elderly women living in the old age home were suffering from depression. Some actions like raising fund through charity approach, counseling, promoting social volunteers or family members to visit old age home and supporting them, etc. should be addressed from the concerned authorities so that depression can be reduced which will support to the well-being and superior life of elderly women.Nepalese Journal of Statistics, 2017, Vol. 1, 29-40
Dexamethasone effect on heart rate variability in preterm infants on mechanical ventilation
Authors: Alonzo Corrie J. , Fairchild Karen D.
Published: December 2017

BACKGROUND:

Dexamethasone is administered to some preterm infants with chronic lung disease to facilitate weaning from mechanical ventilation. Heart rate characteristics (HRC), including heart rate variability (HRV), may be impacted by glucocorticoids and may predict extubation readiness. A commercially available monitor developed for sepsis detection continuously calculates HRV and an HRC index, which are inversely related.

OBJECTIVES:

Determine the impact of dexamethasone on HRV and the HRC index, in relation to extubation success.

METHODS:

We identified 109 preterm infants who received dexamethasone while on mechanical ventilation and had HRC index monitoring data available. Average hourly HRV and HRC index were compared the day before and the day after initiation of dexamethasone in three groups: infants who remained on mechanical ventilation, those who were successfully extubated, and those who were extubated and required reintubation in < 3 days.

RESULTS:

There was a significant increase in HRV and decrease in the HRC index the day after dexamethasone was started (HRV 16.2±0.5 vs 27.6±1.1 ms; HRC index 1.51±0.11 vs. 0.79±0.06 mean SE, p < 0.001). The 63 infants who were extubated within a day of starting dexamethasone had significantly higher HRV compared to those who remained on mechanical ventilation. There was no difference in HRV or its change with dexamethasone in the 45 infants who remained successfully extubated compared to the 18 infants who required reintubation within 3 days.

CONCLUSION:

Dexamethasone improves HRV and lowers the HRC index in preterm infants with chronic lung disease on mechanical ventilation.

Published: December 2017

INTRODUCTION:

Methicillin-resistant Staphylococcus aureus (MRSA) is a common etiological agent of a life-threatening infection in neonatal intensive care units (NICUs). Neonates with very low birth weight and patients with serious diseases are more likely to be exposed to invasive procedures which make them at a high risk of MRSA colonization and infection. Since MRSA colonization is a risk factor for MRSA infection, prevention of MRSA transmission is an important issue in NICUs. NICUs in Japan practice standard contact precautions and active surveillance cultures (ASC) to prevent MRSA transmission. In this report, we analyzed the clinical characteristics of MRSA colonization and infection between January 2010 and December 2015 in our perinatal care center.

METHODS:

We conducted retrospective analysis of 1716 neonates hospitalized in our perinatal care center.

RESULTS:

120 cases had MRSA colonization (6.99%) and among them 33 neonates were infected. The duration of stay ( P≤0.001) and the birth weight ( P≤0.001) showed statistically significant differences between MRSA-colonized neonates and non-MRSA-colonized neonates. The number of central venous catheterization showed statistically significant differences ( P = 0.001) and the number of digestive system diseases showed marginally significant differences ( P = 0.072) between MRSA-colonized non-infected neonates and MRSA-infected neonates.

CONCLUSIONS:

As previous reports have shown, we present that the neonates with central venous catheterization were more likely to be infected with MRSA. We also need to pay attention to neonates with digestive system diseases, showing signs of infection, because they may be potentially infected with MRSA.
Clinical profile and pattern of congenital heart disease in infants of diabetic mother and infants of non-diabetic mother at a tertiary care hospital
Authors: Begum Suraiya , Dey Sanjoy Kumar
Published: December 2017

OBJECTIVES:

To assess the clinical manifestations and pattern of congenital heart diseases (CHD) in infants of diabetic mothers (IDMs) and infants of non-diabetic mothers.

METHODS:

A prospective cross sectional study was carried out at tertiary care center over a period of thirty months. All neonates were included in this study if CHD were identified by echocardiography within this study period. Chi-square test and Fisher’s exact test were used to compare between groups.

RESULT:

Out of 62 neonates, IDMs and non-IDMs were equal in number, male and female ratio was 3 : 2, and majority were delivered by cesarean section (85.5%). Mean gestational age was 35 weeks, 62.3% were preterm, and 37.7% were term. Common clinical presentations were cardiac murmur (61%), and respiratory distress (43.5%). Less common presentations were low SaO2 (27.4%), tachycardia (24.2%), and cyanosis (24.2%). Common combination of presentations were murmur and tachypnea (38.7%); cyanosis and low SaO2 (24.19%); and low SaO2 and tachypnea 15(24.19). The common echocardiographic findings were atrial septal defect (ASD; 72.6%), patent ductus arteriosus (PDA; 45.2%), and ventricular septal defect (VSD; 25.8%). ASD (77.4% vs 67.7%) and VSD (35.5% vs 16.1%) were more in IDMs, and PDA (48.4% vs 41.9%) was more in non-IDMs. These differences were not significant between groups.

CONCLUSION:

Clinical presentation and echocardiographic findings of CHD were similar in IDMs and non-IDMs.

Authors: Huda M , Begum M , Rahman MM , Akter F
Published: December 2017

A weed survey was conducted in Agronomy Field Laboratory, BAUFarm and farmers’ fields of Sutiakhali Natunchar village in Mymensingh district during the period from December 2015 to March 2016 to study the weed vegetation in wheat and  boro rice. Ten fields were selected for each crop from each location. A quadrat of 0.25 m2 was placed randomly at four places in each plot and the weeds within the quadrat were identified and counted species-wise. The results revealed that the composition of weed species in two different crops was different and the composition of weed flora in each crop under different locations was also different. In wheat, a total number of 29 weed species belonging to 16 families were found from all three locations. The infesting weed species were 18 in Agronomy Field Laboratory, 16 species in BAU Farm and 19 species in farmers’ fields. From the five most dominant species, Polygonum hydropiper had the highest relative abundance value in both Agronomy Field Laboratory and BAU Farm and on the other hand, in farmers’ field, a new weed species, Eleusine indica was in the top most of the dominant list. The other weed species which were present in the dominant list of three locations were Cynodon dactylon, Cyperus rotundus, Paspalum distichum, Chenopodium album, Marsilea quadrifolia  and Leucas aspera. In boro rice fields, among the three locations, 25 weed species were observed in total belonging to 13 families. Of which, 20 weed species were found in both Agronomy Field Laboratory and BAU Farm whereas in farmers’ fields, 21 weed species were identified. In both Agronomy Field Laboratory and BAU Farm, Eleocharis atropurpurea had the highest abundance value but in farmers’ field, Cyperus difformis occupied the highest value. The other dominant weed species were Leersia hexandra, Monochoria vaginalis, Echinochloa crusgalli, Paspalum distichum and Alternanthera philoxeroides found in three locations. Many common weeds were present in three locations in a crop but their frequency, uniformity, density and relative abundance value were different. The similarity index of weed species between wheat and boro rice indicated that the infesting weed species between the two crops was less associated. Thus the weed divergence in boro rice with wheat was high. From this study it was clear that the weed infestation was changed by crop and locations. In this study a little bit divergence and ranking of five most abundant weed species and low similarity index value of weed species in different crops under a specific area or among the area indicated that weed control measure should be adopted on crop basis in a specific area considering the dominant weed species.J.

Effect of cow dung as organic manure on the growth, leaf biomass yield of Stevia rebaudiana and post harvest soil fertility
Authors: Zaman MM , Chowdhury T , Nahar K , Chowdhury MAH
Published: December 2017

Organic manures as a source of plant nutrients for the cultivation of field crops has received worldwide attention due to rising costs, rapid nutrient loss and adverse environmental impacts from inorganic fertilizers. A pot experiment was conducted in the net house of the Department of Agricultural Chemistry, BangladeshAgriculturalUniversity, Mymensingh to observe the effects of cow dung on growth, yield of stevia along with post-harvest fertility status of soil. Four treatments of CD viz. 0, 5, 7.5 and 10 t ha–1 in two contrasting soils (acid and non-calcareous) were examined following Completely Randomized Design (CRD) with three replications. Growth and yield attributes increased significantly with the advancement of growth period (60 DAP) and increased rate of CD up to 10 t ha–1. An overall performance of non-calcareous soil was better than acid soil. In non-calcareous soil, the leaf biomass yield was increased by 275% whereas in acid soil it was 268% over control. The acidity of both soils significantly decreased with the increased rate of CD. All essential plant nutrients viz. total N, available P exchangeable K, Ca, Mg, available S, Zn, B and organic matter content of soil were significantly increased with the increased levels of CD up to its highest dose (CD @ 10 t ha–1) in both soils. Thus from the findings of the present research work it can be concluded that for getting optimum leaf biomass yield of stevia along with fertility of both soils CD should be applied @ 10 t ha–1J.

Published: December 2017

This study was conducted to assess the microbial load of Black Bengal goat meat during handling and selling in different markets of Mymensingh, Bangladesh. Total 27 samples were collected from three different places of the city, including KR market, Seshmore and Mesua Bazar. These samples were subjected to determine Total Viable Count (TVC), Total Coliform Count (TCC) and Yeast Mold Count (YMC) by using standard protocols. In raw meat, mean value of TVC were highest in Seshmore market (5.24±0.42 log cfu/g) at 0 hour but having no significant differences with other two places. In case of TCC and YMC highest count were in meat of Mesua Bazar. In case of TCC, difference were observed (P<0.05) among the markets. At 5 hours all the bacterial counts were increased having significant differences with the initial count and in most of the cases the bacterial count crossed the acceptable limit. This was may be due to the unhygienic practices of butchers. Consumers were not conscious. Suggestion has been given to improve the knowledge on hygiene among the meat producers to reduce microbial load.

Published: December 2017

A survey was conducted to assess the socio-economic status of the fishers of the old Brahmaputra River in Mymensingh Sadar Upazila from April 2011 to March 2012. Data were collected from randomly selected 30 traditional fishermen of Kagdahor, Shambhuganj, Kawatkhali, BAU Campus, Shesmor, Sutiakhali, Char Kalibari, Char Ishwardia and Char Nilakshmia using a well-structured questionnaire. The research revealed that besides fishing, the fishers occasionally undertook a variety of non-fishery related activities. The average annual income ranged from 25,000-84,000 BDT which significantly depends on fishing effort, season of the year and market price of fish. Majority of them belonged to age range 15-30 years (59.25%). Almost 63% of the fishermen were illiterate and cannot write their names, while only 14.81% had received education up to primary level. It was also revealed that family size of 60% of the fishermen were medium consisting of 5-7 members while only 10% had small family size of 2-4 members. Despite their low income and large family sizes, 80% of the fishermen were living in semi-constructed houses. Sometimes for coping with adverse situation many of them took loans from different national and local NGOs like BRAC, ASSA. A declining trend of fish resources in the river and lack of working capital were identified as the major constrains for the fishers of the Old Brahmaputra River.Res. Agric. Livest.

Published: December 2017

Following the declining stocks of Sardinella aurita within the coastal waters of Ghana, this study aimed at examining some population parameters of Sardinella aurita as a guide for managing this important stock sustainably. Length-frequency data of 717 samples were obtained from June, 2014 to January 2015 and measured for total length with the resultant data analyzed using FiSAT II. The asymptotic length (L∞) and growth rate (K) were 21.53 cm SL and 0.25yr-1 respectively. The theoretical age at birth (t0), longevity (tmax) and growth performance index (ϕ) were -0.74yr-1, 12 years and 1.849 respectively. Total mortality rate (Z), natural mortality rate (M) and fishing mortality rate (F) were 3.17, 0.76 and 2.41yr-1 respectively. The ages at first recruitment and first capture signaled future collapse of the stock, in the absence of proper management interventions. VPA outcome showed that mid- lengths of 11 cm and 12 cm SL experienced the highest harvesting rate with MSY estimated at 7733 tons. The recruitment pattern was continuous with two major recruitment pulses. Exploitation rate (Ecurr=0.76) was higher than the maximum exploitation rate (Emax=0.56), indicating unsustainable exploitation. Further, the fishing regime fell within the overfished stage based on the Quadrant Rule. For sustainable exploitation of this commercial fish species, implementation of relevant biological reference points through reduction in fishing efforts, creation of marine protected areas and mesh size regulation are urgently advocated.Res.

Stability, Deactivation, and Regeneration of Chloroaluminate Ionic Liquid as Catalyst for Industrial C4 Alkylation
Authors: Li Xiang , Zhang Jie , Huang Chongpin , Chen Biaohua , Li Jianwei , Lei Zhigang
Published: December 2017

Alkylation of isobutane and 2-butene was carried out in a continuous unit using triethylamine hydrochloride (Et3NHCl)-aluminum chloride (AlCl3) ionic liquid (IL) as catalyst. The effects of impurities such as water, methanol, and diethyl ether on the stability of the catalytic properties and deactivation of the ionic liquid were studied in the continuous alkylation. In the Et3NHCl-2AlCl3 ionic liquid, only one half of the aluminum chloride could act as the active site. With a molar ratio of 1:1, the active aluminum chloride in the ionic liquid was deactivated by water by reaction or by diethyl ether through complexation while the complexation of aluminum chloride with two molecular proportions of methanol inactivated the active aluminum chloride in the ionic liquid. The deactivation of chloroaluminate ionic liquid was observed when the active aluminum chloride, i.e., one half of the total aluminum chloride in the ionic liquid, was consumed completely. The regeneration of the deactivated ionic liquid was also investigated and the catalytic activity could be recovered by means of replenishment with fresh aluminum chloride.

Published: December 2017

A quantifiable, quick, inexpensive and reproducible predictor is needed to decide if caustic substance ingestion results in burn regardless of the symptoms. A multicenter cohort study was conducted to investigate the predictive value of red cell distribution width (RDW) in detecting the esophageal burns. The data of 174 patients were retrospectively analyzed. Eleven patients were excluded due to inability to define the substance ingested. Complete blood count (CBC) was taken at admission, and an esophagogastroduodenoscopy was performed within the first 12–24 h in all patients, regardless of their symptoms. The age and gender of the patients, the types of substances ingested, the parameters in the CBC and the severity of the esophageal injury were correlated. Esophageal burns were diagnosed in 38 of 163 patients (23.3%). The risk of esophageal burn with RDW values below 12.20 was significantly lower. Multivariate analysis showed that RDW was the most significant predictor of esophageal burn (p = 0.000, odds ratio (OR) 7.74 (95% confidence interval (CI), 3.02–19.9)). Receiver operating characteristic (ROC) curve analysis demonstrated 84.2% sensitivity at a cut-off value of 12.20 for RDW. The results showed that CBC parameters could avoid unnecessary esophagogastroduodenoscopy. The RDW values regardless of the symptomatology is a good predictor of esophageal burns, and an RDW value over 12.20 shows the increased risk of esophageal burn.

Authors: Cheng Lijun , Hao Liang , Lu Yun
Published: December 2017

To overcome the recovery disadvantages of Bi2O3 photocatalyst in the form of powder, Bi2O3 photocatalyst coatings were developed via a ball milling, followed by the calcination method. The composition and structure evolution rules of the as-synthesized samples were analyzed based on XRD (X-ray powder diffraction) patterns and SEM (scanning electron microscope) observations. XPS (X-ray photoelectron spectroscopy) and UV-Vis (Ultraviolet-visible) spectra were also employed to characterize the samples. The results showed that monoclinic Bi2O3 coatings were obtained after sintering Bi coatings at 673 or 773 K for 2 h, while calcination at a higher temperature and for a longer time resulted in monoclinic and triclinic mixed-phase Bi2O3 coatings. Bi2O3 coatings with a radial growth structure assembled by nanosheets could be realized at a lower temperature lasting for a longer time, while sintering at a higher temperature with relatively short oxidation time led to tangential growth structure. Photodegradation of malachite green solution under simulated solar irradiation for 180 min showed that the largest degradation efficiency of 91.49% was achieved over the photocatalyst coatings calcined at 873 K for 5 h. Additionally, the degradation efficiency was maintained above 80% even after three cycles.
Urban Land Allocation Model of Territorial Expansion by Urban Planners and Housing Developers

Published: December 2017

Agent-based models have recently been proposed as potential tools to support urban planning due to their capacity to simulate complex behaviors. The complexity of the urban development process arises from strong interactions between various components driven by different agents. AMEBA (agent-based model for the evolution of urban areas) is a prototype of an exploratory, spatial, agent-based model that considers the main agents involved in the urban development process (urban planners, developers, and the population). The prototype consists of three submodels (one for each agent) that have been developed independently and present the same structure. However, the first two are based on a land use allocation technique, and the last one, as well as their integration, on an agent-based model approach. This paper describes the conceptualization and performance of the submodels that represent urban planners and developers, who are the agents responsible for officially launching expansion and defining the spatial allocation of urban land. The prototype was tested in the Corredor del Henares (an urban–industrial area in the Region of Madrid, Spain), but is sufficiently flexible to be adapted to other study areas and generate different future urban growth contexts. The results demonstrate that this combination of agents can be used to explore various policy-relevant research questions, including urban system interactions in adverse political and socioeconomic scenarios.

Published: December 2017

Soil erosion, as a significant contributor to nonpoint-source pollution, is ranked top of sediment sources, pollutants attached to sediment, and pollutants in the solution in surface water. This paper is focused on the design of mathematical model intended to predict the total content of nitrogen (N), phosphorus (P), and potassium (K) in bottom sediments in small water reservoirs depending on water erosion processes, together with its application and validation in small agricultural watershed of the Tisovec River, Slovakia. The designed model takes into account the calculation of total N, P, and K content adsorbed on detached and transported soil particles, which consists of supplementing the soil loss calculation with a determination of the average nutrient content in topsoils. The dissolved forms of these elements are neglected in this model. Validation of the model was carried out by statistical assessment of calculated concentrations and measured concentrations in Kľušov, a small water reservoir (Slovakia), using the t-test and F-test, at a 0.05 significance level. Calculated concentrations of total N, P, and K in reservoir sediments were in the range from 0.188 to 0.236 for total N, from 0.065 to 0.078 for total P, and from 1.94 to 2.47 for total K. Measured nutrient concentrations in composite sediment samples ranged from 0.16 to 0.26% for total N, from 0.049 to 0.113% for total P, and from 1.71 to 2.42% for total K. The statistical assessment indicates the applicability of the model in predicting the reservoir’s sediment quality detached through erosion processes in the catchment.

Published: December 2017

Lunar impact craters are important for studying lunar surface morphology because they are the most typical morphological units of the Moon. Impact crater descriptive indices can be used to describe morphological features and thus provide direct evidence for both the current state and evolution history of the Moon. Current description methods for lunar impact craters are predominantly qualitative, and mostly focus on their morphological profiles. Less attention is paid to the detailed morphological features inside and outside of the craters. A well-established and descriptive index system is required to describe the real morphological features of lunar impact craters, which are complex in a systematic way, and further improve study, such as heterogeneity analyses of lunar impact craters. This study employs a detailed lunar surface morphological analysis to propose a descriptive index system for lunar impact craters, including indices for the description of individual craters based on their morphological characteristics, spatial structures and basic composition (i.e., crater rim, crater wall, crater floor, central uplift, and ejecta), and indices for crater groups, including spatial distribution and statistical characteristics. Based on the proposed descriptive index system, a description standard for lunar impact craters is designed for categorising and describing these indices in a structured manner. To test their usability and effectiveness, lunar impact craters from different locations are manually detected, and corresponding values for different indices are extracted and organised for a heterogeneity analysis. The results demonstrate that the proposed index system can effectively depict the basic morphological features and spatial characteristics of lunar impact craters.

Published: December 2017

The material lithium indium diselenide, a single crystal neutron sensitive semiconductor, has demonstrated its capabilities as a high resolution imaging device. The sensor was prepared with a 55 μ m pitch array of gold contacts, designed to couple with the Timepix imaging ASIC. The resulting device was tested at the High Flux Isotope Reactor, demonstrating a response to cold neutrons when enriched in 95% 6 Li. The imaging system performed a series of experiments resulting in a <200 μ m resolution limit with the Paul Scherrer Institute (PSI) Siemens star mask and a feature resolution of 34 μ m with a knife-edge test. Furthermore, the system was able to resolve the University of Tennessee logo inscribed into a 3D printed 1 cm 3 plastic block. This technology marks the application of high resolution neutron imaging using a direct readout semiconductor.
Diversity of Cell Wall Related Proteins in Human Pathogenic Fungi

Published: December 2017

The cell wall is one of the major keys to fungal identity. Fungi use their cell wall to sense the environment, and localize nutrients and competing microorganism. Pathogenic species additionally modify their cell walls to hide from a host’s immune system. With the growing number of fungal infections and alarming shortage of available drugs, we are in need of new approaches to fight pathogens. The cell wall seems to be a natural target, since animal host cells are devoid of it. The current knowledge about fungal cell wall components is often limited, and there is huge diversity both in structure and composition between species. In order to compare the distribution of diverse proteins involved in cell wall biosynthesis and maintenance, we performed sequence homology searches against 24 fungal proteomes from distinct taxonomic groups, all reported as human pathogens. This approach led to identification of 4014 cell wall proteins (CWPs), and enabled us to speculate about cell wall composition in recently sequenced pathogenic fungi with limited experimental information. We found large expansions of several CWP families, in particular taxa, and a number of new CWPs possibly involved in evading host immune recognition. Here, we present a comprehensive evolutionary history of fungal CWP families in the context of the fungal tree of life.
Nondestructive Evaluation of Strain-Induced Phase Transformation and Damage Accumulation in Austenitic Stainless Steel Subjected to Cyclic Loading
Authors: Kim Chungseok
Published: December 2017

Strain-induced phase transformation and damage accumulation in austenitic stainless steel subjected to cyclic loading were investigated by nondestructive evaluation. The cyclic loading test was performed at various strain amplitudes at the same strain rate. The volume fraction of the strain-induced phase transformation (α′-martensite) was determined by ferrite scope and magnetic coercivity measurement. The damage accumulation and microstructure of cyclic loading specimens were characterized by microstructural observation. The cyclic hardening and cyclic softening behavior are discussed in terms of the generation of strain-induced martensite phases and a dislocation substructure at each strain amplitude. The volume fraction of the strain-induced phase increased with the strain amplitude. The increase in α′-martensite was evaluated by measuring the ultrasonic nonlinearity parameter. The presence of α′-martensite is sufficient to distort the austenitic matrix due to an interface misfit between the austenite matrix and α′-martensite, resulting in wave distortion of the longitudinal wave. From this wave distortion, super-harmonics may be generated with nucleation of the strain-induced martensite, a process that strongly depends on the strain amplitude.
Geological Modelling and Validation of Geological Interpretations via Simulation and Classification of Quantitative Covariates
Authors: Adeli Amir , Emery Xavier , Dowd Peter
Published: December 2017

This paper proposes a geostatistical approach for geological modelling and for validating an interpreted geological model, by identifying the areas of an ore deposit with a high probability of being misinterpreted, based on quantitative coregionalised covariates correlated with the geological categories. This proposal is presented through a case study of an iron ore deposit at a stage where the only available data are from exploration drill holes. This study consists of jointly simulating the quantitative covariates with no previous geological domaining. A change of variables is used to account for stoichiometric closure, followed by projection pursuit multivariate transformation, multivariate Gaussian simulation, and conditioning to the drill hole data. Subsequently, a decision tree classification algorithm is used to convert the simulated values into a geological category for each target block and realisation. The determination of the prior (ignoring drill hole data) and posterior (conditioned to drill hole data) probabilities of categories provides a means of identifying the blocks for which the interpreted category disagrees with the simulated quantitative covariates.
Phytoestrogenic Activity of Blackcurrant Anthocyanins Is Partially Mediated through Estrogen Receptor Beta

Published: December 2017

Phytoestrogens are plant compounds with estrogenic effects found in many foods. We have previously reported phytoestrogen activity of blackcurrant anthocyanins (cyanidin-3-glucoside, cyanidin-3-rutinoside, delphinidin-3-glucoside, and delphinidin-3-rutinoside) via the estrogen receptor (ER)α. In this study, we investigated the participation of ERβ in the phytoestrogen activity of these anthocyanins. Blackcurrant anthocyanin induced ERβ-mediated transcriptional activity, and the IC50 of ERβ was lower than that of ERα, indicating that blackcurrant anthocyanins have a higher binding affinity to ERβ. In silico docking analysis of cyanidin and delphinidin, the core portions of the compound that fits within the ligand-binding pocket of ERβ, showed that similarly to 17β-estradiol, hydrogen bonds formed with the ERβ residues Glu305, Arg346, and His475. No fitting placement of glucoside or rutinoside sugar chains within the ligand-binding pocket of ERβ-estradiol complex was detected. However, as the conformation of helices 3 and 12 in ERβ varies depending on the ligand, we suggest that the surrounding structure, including these helices, adopts a conformation capable of accommodating glucoside or rutinoside. Comparison of ERα and ERβ docking structures revealed that the selectivity for ERβ is higher than that for ERα, similar to genistein. These results show that blackcurrant anthocyanins exert phytoestrogen activity via ERβ.

Epilepsy is a common chronic neurological disorder disease, and there is an urgent need for the development of novel anticonvulsant drugs. In this study, the anticonvulsant activities and neurotoxicity of 12 cinnamic acid derivatives substituted by fluorine, chlorine, bromine, and trifluoromethyl groups were screened by the maximal electroshock seizure (MES) and rotarod tests (Tox). Three of the tested compounds (compounds 3, 6 and 12) showed better anticonvulsant effects and lower neurotoxicity. They showed respective median effective dose (ED50) of 47.36, 75.72 and 70.65 mg/kg, and median toxic dose (TD50) of them was greater than 500 mg/kg, providing better protective indices. Meanwhile, they showed a pentylenetetrazol (PTZ) ED50 value of 245.2, >300 and 285.2 mg/kg in mice, respectively. Especially, the most active compound 3 displayed a prominent anticonvulsant profile and had lower toxicity. Therefore, the antiepileptic mechanism of 3 on glycosylation changes in chronic epilepsy in mice was further investigated by using glycomics techniques. Lectin microarrays results showed that epilepsy was closely related to abnormal glycosylation, and 3 could reverse the abnormal glycosylation in scPTZ-induced epilepsy in mice. This work can provide new ideas for future discovery of potential biomarkers for evaluation of antiepileptic drugs based on the precise alterations of glycopatterns in epilepsy.
