Effect of agricultural pesticide on precocious puberty in urban children: an exploratory study
Authors: Suh Junghwan , Choi Han Saem , Kwon Ahreum , Chae Hyun Wook , Kim Ho-Seong
Published: January 2020

Background: The incidence of precocious puberty has increased throughout the 20th century. The association between precocious puberty and endocrine disrupting chemicals including agricultural pesticides has been a subject of global study, but human data are lacking. Purpose: We investigated the relationship between agricultural pesticides and the development of precocious puberty.Methods: We enrolled 60 female subjects at Severance Children’s Hospital from December 2015 to January 2017. Of them, 30 were diagnosed with precocious puberty, while the other 30 prepubertal girls were enrolled as normal controls. We investigated their clinical characteristics and analyzed the urinary levels of 320 different agricultural pesticides.Results: Agricultural pesticide was detected in one of 30 patients with precocious puberty (3.3%) versus 2 of 30 girls in the normal control group (3.3% vs. 6.7%, P=0.554). Dinotefuran, a neonicotinoid-class insecticide, was detected in the samples of all 3 positive subjects.Conclusion: Our results showed no relationship between agricultural pesticides and the development of precocious puberty. Larger sample sizes and robustly controlled variables are necessary to further investigate this topic.
Demography of the largest and most endangered Brazilian parrotfish, Scarus trispinosus, reveals overfishing
Authors: Roos NC , Taylor BM , Carvalho AR , Longo GO
Published: January 2020

Many parrotfishes (Labridae: Scarinae) have life history traits, including late maturation and long lifespans, that make them vulnerable to overfishing. The greenbeak parrotfish Scarus trispinosus is the largest Brazilian endemic parrotfish and has been harvested in reef-associated fisheries along the coast. After a sharp population decline, S. trispinosus is now considered by the IUCN to be an Endangered species. We provide an assessment of age-based and reproductive biology for this species and discuss applications for fisheries management. We sampled 95 individuals from inshore and offshore reefs from Rio Grande do Norte state, northeast Brazil, both obtained from artisanal fishing landings and fishery-independent collections. All sampled specimens were females with fork lengths (FL) ranging from 8.1 to 55.9 cm and ages ranging from 0.3 to 7 yr, with estimated median maturity (L50) of 39.2 cm FL and median age (A50) of 4.2 yr. Size class distributions indicate that the inshore reefs are mostly inhabited by juveniles under L50, whereas the offshore reefs are inhabited by mature individuals, suggesting an ontogenetic habitat shift from inshore to offshore reefs around the timing of maturation. The fishing pressure on this species is concentrated in inshore reefs, therefore mostly on immature individuals, which may be severely affecting the reproductive capacity of this species. This information is useful to guide size-based fisheries management, such as regulating minimum capture size and fishing gears that capture individuals smaller than L50. Managing fisheries of endangered species with late maturity and complex reproductive cycles such as S. trispinosus is imperative to aid recovery.

A unified model for the governing dynamics of agricultural frontier zones
Authors: Troskosky Christopher Barber , White Jonathan Mark , Gaižauskas Lukas
Published: January 2020

We present a unified model for the movement of agricultural frontiers based on the construction of the parallax shift and its relation to normalizable science. The model is based on data from the Baltic Basin, where for thousands of years, complex and semi-complex hunter/gatherer/fishers and agriculturalists remained in an equilibrium state. When agriculturalization occurred, it occurred in a punctuated
equilibrium manner, which defies current models of agricultural frontier movement, and by extension, current understandings of the underlying dynamics of social change. This new model is a modification of Structuration (Giddens 1984), with the emerging field of selforganized criticality within Physics (Bak et. al 1988; Brunk 2002b). These modifications require two additional governing dynamics not included in Giddens’s original formulation. When joined to an agricultural frontiers model with selective information permeability, these governing dynamics allow for societies to undergo punctuated equilibrium change under stress affect conditions. This results in critical behavior without the need for chaotic state change (Bak et. al 1988). This results in the creation of new material culture assemblages, reflecting new societal structures which are in equilibrium with the social and environmental landscape. The model is scale independent in both space and time, presenting some interesting conclusions.
Laidojimas pilkapiuose krikščioniškojoje Lietuvoje

Lietuvos vėlyvųjų viduramžių – ankstyvųjų naujųjų laikų (XIV a. pabaigos – XVIII a.) senkapių kontekste išsiskiria kapai, įkasti į geležies amžiaus pilkapius. Iki šiol Lietuvoje rasta mažiausiai 400 vėlyvų kapų 26-iuose pilkapynuose, dar bent apie 25-is pilkapynus turima fragmentiškos informacijos. Ankstyviausi kapai senuose pilkapiuose datuotini XIV a. pabaiga – XV a., tačiau masine tokia laidosena tapo XVI–XVII a. Pagrindinis šio papročio sklaidos arealas yra Žemaitija ir Šiaurės Lietuva. Įranga, orientacija, įkapių komplektais šie kapai niekuo neišsiskiria iš istorinių laikų senkapių. Kapinynų sugrįžimą į senuosius pilkapynus reikia sieti su Lietuvos christianizacija. Viena vertus, iki XVI a. Lietuvos provincijos gyventojų evangelizacija nebuvo intensyvi, todėl neįsitvirtino laidojimas bažnyčių šventoriuose ir krikščioniškos apeigos. Kita vertus, Reformacijos ir ypač Kontrreformacijos laikotarpyje sutankintas bažnyčių tinklas, išaugęs Bažnyčios spaudimas laikytis krikščioniškų laidojimo apeigų bei lupikiški mokesčiai už jas, krikščionybės autoriteto stoka galėjo skatinti gyventojų priešiškumą. Jiems teko ieškoti nuošalesnių vietų kapinynams, ir jas kai kurios bendruomenės rado senuose pagoniškuose pilkapynuose.

Published: January 2020

Recently, the flipped classroom instructional approach has received much attention from teachers of different subjects around the world. This new pedagogical model has been reported to be a potential method in the area of EFL teaching. In Vietnam, teaching English grammar has mainly focused on students’ acquisition of grammar rules without much practical application in real communicative situations. This case study aims at investigating the affordances perceived by students in a flipped English grammar class in order to help language teachers to harness the approach to enhance their students’ learning. The qualitative research design was adopted in the study. Thirty-four students majoring in the English language at a university in Vietnam attended a 10-week flipped grammar class. The instruments include semi-structured interviews with ten students randomly selected from the participants. Thematic analysis was performed to address the qualitative data drawing on the Activity Theory framework. Twelve affordances of the flipped classroom approach in English grammar instruction such as being self-paced in learning, offering opportunities to voice opinions, saving time for in-class communicative activities and facilitating learning English grammar communicatively were identified. The results of the study offer valuable implications for the application of this model in teaching English as a foreign language, especially in the context of Vietnam.

Locating a new industrial area involves a strategic decision that covers several criteria with consideration for socio-economic benefits and environmental sustainability alongwith technical, and political issues. These different criteria are described using a number of indicators in terms of quantity and quality with some possible uncertainty. Decision making thus requires appropriate tools for data collection, analysis and knowledge management to address this multidisciplinary situation. This paper tries to find out the comprehensive method for industrial site location, a sustainable approach for finding the most suitable solution. Identifying the location determinants and site suitability models used for allocating an industrial site is observed to be an essential aspect of siting of industry, as such; level of decision making is dependent on predefined constraints. Multicriteria decision making method (M.C.D.M) seems to be a consistent and efficient solution which forms the basis for locating multiple sites for industrial activity in any delineated area.

Indian Railways operates both long distance and suburban passenger trains and freight services daily in the country. Trains get delayed frequently due to several reasons such as, severe weather conditions such as fog, traffic, signal failure, derailing of trains, accidents, etc, and this delay is propagated from station to station. If we can predict this in advance - it would be of great help for the commuters to plan their journey either for an earlier departure or postpone, and also lets railways to take measures to avoid delays further. In this paper, we used decision tree, a machine learning method used for predicting train delays, and Recurrent Neural Networks distinguished with various fixtures. For predicting train delays, Recurrent Neural networks with 2 layers and 22 neurons per each layer gave best results with an average error of 122 seconds.

Making adobes with the best mechanical properties for the construction of earthen housings is the overall goal of this work. Specifically, we study the influence of rice straw on the physical and mechanical properties of these adobes. The physical and mechanical properties (compressive and flexural strength) of adobes (mixture of sandy clay and rice straw) have been studied with different proportions of straw in the mixture. It is a question of determining the quantity of stalks of rice straw making it possible to optimize the mechanical performances of the composite. Various compositions have been considered with mass concentrations of rice straw ranging from 0 to 40% relative to the volume of clay sand to make 4×4×16cm prismatic specimens. The results obtained during physical and mechanical tests were presented in the form of a graph. The analysis of these data shows that the optimal addition of rice straw in the clay matrix is 25% for a better compromise between the compressive and tensile strengths. The improvement of the physical and mechanical properties of adobes is related to the good adhesion between the rice straw and the clay matrix, to the high tensile strength of the rice straw and finally to a good distribution of cracks in the composites.

The common practice of Municipal solid waste disposal method in developing countries is an unlined landfill dumping site. Due to this the natural resources land, water and air get polluted and also severely affected by the public living around the dumping yard. In this study, Srinivasapuram dumpsite in Thanjavur City Municipal Corporation area, India has been selected to investigate the quality of groundwater. Groundwater samples collected from 25 locations were tested as per standards for physical, chemical characteristics. The classical contour mapping method has been used to detect information from the recorded ground water quality data. Surfer 6.0 software has been used to convert the spatial data into equivalent contour map. Graphical method has been used to decide the area enclosed by each contour line. The water quality standards recommended by BIS and WHO were used to classify the critical regions based on the ground water contamination level. The water quality parameters such as pH value, Electrical conductivity, Total dissolved solids (TDS), Total Hardness (TH), Iron and Fluoride were considered for this analysis and other parameters were not included. All the collected groundwater samples the pH values are within the permissible limit of 6.5-8.5. The Electrical Conductivity vales range between 0.5mho/cm and 5.7mho/cm. The TDS values ranges between 200 and 3024 mg/l. The concentration of TDS is higher than the permissible level of the samples which are nearby the dumping yard as the contour lines are assembling around the dumpsite. The concentration of chlorides in all the samples under investigation is 12.4 to 1316 mg/l. It has been observed that concentration of total hardness (TH) of water samples varies from 118 mg/l to 2070mg/l. The presence of high concentration of iron and fluoride in the water samples adjacent to dumping yard indicate that it would have contaminated by leachate movement from MSW. The contour plots also reveal that the groundwater was contaminated as per the tests conducted for physical and chemical parameters.

Power deficiency is one of the major problems that the whole world is facing now. This is happening because of the immense increase in the world’s population and the global increase of industrialization. So in order to minimize the consumption of power, an energy efficient current source is designed with the help of Field Programmable Gate Array (FPGA). This work gives light on how the power variation takes place in a current source with an increase in frequency value. In this research work, the current source is implemented on 28 nanometers (nm) Airtx-7 FPGA. The work is demonstrated on Xilinx 14.1 ISE simulator. VHSIC Hardware Description Language (VHDL) is used for writing the code of current source. The frequency of current source with Airtx-7 FPGA is increased from 100MHz to 5GHz. It is analyzed that the total power consumption is less as the value of frequency is low. So it is always advisable to operate the device at a lower frequency range in order to save more energy.

Over the past few decades, stroke has become one of the most common cause deaths. The heart muscle, like every other organ or tissue in our body, needs oxygen-rich blood to survive. Coronary artery disease means narrowing of the coronary arteries. This narrowing is due to a buildup of plaque in the walls of the arteries. Computational simulations provide invaluable information that is extremely difficult to obtain experimentally and is one of the many CFD sample applications in the biomedical area in which blood flow through an abnormal artery can be predicted. CFD analysis is increasingly performed to study fluid phenomena inside the human vascular system.

There are many parts in an electrical appliance, each performing various operations. In particular, if a part fails, then the appliance will not be able to carry out its operations in a better way. Thus, to determine the significant part, fuzzy cognitive map can be used. However, it is noticed that in the washing machine, the outcome of the experiment lists all the parts to play an equal role. Therefore, in order to reduce the cost, the circuit must be minimized which can be done using a Java script software. Using the above circuit in the washing machine, it is easy to identify the fault in the part even before it gets damaged.

Solid oxide fuel cell (SOFC) component has always under development to enhance catalytic activity. Components such as anode, cathode and electrolyte must have better structure and behavior for good SOFC performance. Traditional Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) cathode in solid oxide fuel cell application has been deterred several inappropriate circumstances such as high thermal expansion coefficient (TEC) and chemical instability. Sm0.2Ce0.8O1.9 (SDC) electrolyte and Silver (Ag) are added into BSCF to overcome the problem and has better material characterization and thermal stability, The composite cathode powder BSCF-SDC was prepared by high speed ball milling technique with mixture of 50wt% BSCF and 50wt% SDC commercial powder. The powders were then dried and calcined at 950oC for 2 hour. Silver (Ag) with 1wt%, 3wt% and 5wt% were milled respectively with BSCF-SDC by low speed ball milling technique. The developed composite cathode was then examined by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), dilatometer and Thermogravimetric Analysis (TGA). The vivid distinct phase of BSCF, SDC and Ag and absence of additional secondary phase was confirmed by XRD analysis indicating good phase structure compatibility. This also assured that less chemical reaction was happened during low speed milling process for BSCF-SDC-Ag as minor secondary phases are detected. However, milling process at high speed and high calcination temperature did destruct single phase of BSCF in BSCF-SDC composite cathode. However, Ag obtains its role to retain back the BSCF crystalline phase. The higher the percent of Ag added, the higher the BSCF peak retain. The absence of addition bonding in FTIR analysis demonstrating excellent structure compatibility of BSCF, SDC and Ag during milling process. There was no significant additional bonding appeared in BSCF-SDC-Ag after milling process. The thermal expansion coefficient (TEC) were determined using dilatometer, manifesting closer TEC mismatch between BSCF-SDC-Ag cathode composite and SDC electrolyte compared to BSCF-SDC. TEC is essential to be matched as it could prevent spallation during elevated operation temperature of SOFC. TGA analysis indicated cathode composite experiencing very less changes of weight when it was heated up 1000oC. BSCF is revealed of decomposition occurring after 800oC. Result revealed that Ag exhibited desirable thermal and structure compatibility with BSCF-SDC as promising SOFC cathode which beneficial from medium scale automobile to high scale power plant application.

In this paper, 1 group of plain concrete square columns 150×150×600 mm and 11 groups of concrete columns reinforced with glass fiber reinforced polymer (GFRP) were cast and tested, each group contains of 3 specimens. These experiments investigated effect of the main reinforcement ratio, stirrup spacing and contribution of longitudinal GFRP bars on the load carrying capacity of GFRP reinforced concrete (RC) columns. Based on the experiment results, the relationship between load-capacity and reinforcement ratio and the plot of contribution of longitudinal GFRP bars to load-capacity versus the reinforcement ratio were built and analyzed. By increasing the reinforcement ratio from 0.36% to 3.24%, the average ultimate strain in columns at maximum load increases from 2.64% to 75.6% and the load-carrying capacity of GFRP RC columns increases from 3.4% to 25.7% in comparison with the average values of plain concrete columns. Within the investigated range of reinforcement ratio, the longitudinal GFRP bars contributed about 0.72%-6.71% of the ultimate load-carrying capacity of the GFRP RC columns. Meanwhile, with the same configuration of reinforcement, contribution of GFRP bars to load-carrying capacity of GFRP RC columns decreases when increasing the concrete strength. The influence of tie spacing on load-carrying capacity of reinforced columns was also taken into consideration. Additionally, experimental results allow us to propose some modifications on the existing formulas to determine the bearing capacity of the GFRP RC column according to the compressive strength of concrete and GFRP bars.

Liveliness detection aims to determine whether the iris presented to the sensor belongs to a live subject or it is a fake one. Liveliness detection is to classify input sample into one of the category between fake and real. This work proposes an improved biometric system which recognizes the liveliness of the iris samples in order to increase the security. In this work, the dataset of UBIRIS.v2 is used where input samples are segmented into pupil, sclera and iris and these individual segments are filtered to enhance the quality of the samples. Further, the segmentation using Fuzzy C-Mean and K-Mean clustering methods is done. Different features are extracted and fused thereafter. Fused features are then used as a training data. For testing purpose, a combined dataset of original and fake samples is used and accuracy of the system is calculated with a novel hybrid classifier AHyBrK which is a combination of ANN and KNN. Results achieve 97% accuracy in differentiating between fake and live which is 8.2% better than KNN and 5.1% better than ANN

Air pollution has a very adverse impact on human beings and our ecosystem. With the rampant industrialization and exponential growth in automobile industry, the air gets highly contaminated by harmful toxins & gases released from their emissions which results into many hazardous diseases like asthma, bronchitis, mental illness, lung cancer etc. Hence the air pollution should be carefully monitored and efficiently controlled. Using internet of things (IoT) we can simultaneously gather pollutants level in highly explicit areas and transmit the data to centralized controlling and monitoring unit where suitable steps can be taken to warn people so as to reduce the level of pollutants in the air significantly.
