To understand the amplification of the cDNA sequence for MyoG gene from Guangxi Bama mini-pig by RT-PCR,and explore the clustering relationships with other species,and the PCR-SSCP technique was used analyze the polymorphism of exon 3 among Guangxi Bama mini-pig,Landrace,Duroc and Yorkshire.The PCR primers were designed according to the sequence of pig MyoG gene published in GenBank,and the total RNA from muscle tissues of Guangxi Bama mini-pig was used as the template for RT-PCR,and then the obtained target fragments were purified,cloned,indentified,and sequenced.The genomic DNA of the 30 individuals was extracted from the ear tissues of four breeds of pigs,and then the exon 3 was amplified by the PCR method for SSCP analysis.The results showed that the length of the coding region for the cloned MyoG gene in Guangxi Bama mini-pig was 675 bp,and the sequence homologies of MyoG gene compared with the sequence of sichuan wild boar,human,cow and mouse were 99.7%,93.8%,91.7%,90.5%,respectively.The MyoG genes were conservative among different species in the evolution.Compared with the Sichuan wild boar,the cDNA sequence of the cloned MyoG gene from Guangxi Bama mini-pig occurred two gene mutations at 233 and 642 sites.The genotype of MyoG gene of Guangxi Bama mini-pig was only type AA,but the genotype of Landrace,the Duroc,the Yorkshire was only type AB.There was no polymorphism within the four groups.


Strike‐slip faults have long been known for characteristic near‐fault landforms such as offset rivers and strike‐parallel valleys. In this study, we use a landscape evolution model to investigate the longer‐term, catchment‐wide landscape response to horizontal fault motion. Our results show that strike‐slip faulting induces a persistent state of disequilibrium in the modeled landscapes brought about by river lengthening along the fault alternating with abrupt shortening due to stream capture. The models also predict that, in some cases, ridges oriented perpendicular to the fault migrate laterally in conjunction with fault motion. We find that ridge migration happens when slip rate is slow enough and/or soil creep and river incision are efficient enough that the landscape can respond to the disequilibrium brought about by strike‐slip motion. Regional rock uplift relative to baselevel also plays a role, as topographic relief is required for ridge migration. In models with faster horizontal slip rates, stronger rocks, or less efficient hillslope transport, ridge mobility is limited or arrested despite the continuance of river lengthening and capture. In these cases, prominent steep, fault‐facing facets form along well‐developed fault valleys. Comparison of landscapes adjacent to fast‐slipping (>30 mm/yr) and slower‐slipping (≤1 mm/yr or less) strike‐slip faults in California, USA, reveals features that are consistent with model predictions. Our results highlight a potential suite of geomorphic signatures that can be used as indicators of horizontal crustal motion and geomorphic processes in strike‐slip settings even after river capture has diminished or erased apparent offset along the fault.


Understanding the various eating habits of different population groups, according to the geographical area, is critical to develop evidence-based policies for nutrition and food safety. The FAO/WHO Global Individual Food consumption data Tool (FAO/WHO GIFT) is a novel open-access online platform, hosted by FAO and supported by WHO, providing access to harmonized individual quantitative food consumption (IQFC) data, especially in low- and middle-income countries (LMICs).

 FAO/WHO GIFT disseminates IQFC data as ready-to-use food-based indicators in the form of infographics, and as microdata. The infographics intend to facilitate the use of these data by policy makers, providing an overview of key data according to population segments and food groups. The microdata is publicly available for download, and is intended for users that would like to do further analysis of the data.

 FAO/WHO GIFT is a growing repository. By June 2020, 14 datasets were available for dissemination and download, and an additional 44 datasets will be made available by 2022. FAO/WHO GIFT also provides an inventory of existing IQFC data worldwide, which currently contains detailed information on 268 surveys conducted in 105 countries.

 FAO/WHO GIFT collates, harmonizes and disseminates IQFC data collected in different countries. This harmonization is aimed at enhancing the consistency and reliability of nutrient intake and dietary exposure assessments globally. FAO/WHO GIFT is developed in synergy with other global initiatives aimed at increasing the quality, availability and use of IQFC data in LMICs to enable evidence-based policy-making for better nutrition and food safety.


Kern U, Martin C, Scheicher S, Müller H: Effects of botulinum toxin type B on stump pain and involuntary movements of the stump. Am J Phys Med Rehabil 2004;83:396–399. Patients who had previously undergone amputation of the arm (n = 2) or leg (n = 2) were treated with botulinum toxin type B injections at several trigger points of their stump musculature. We administered a total dose of 2500 IU of botulinum toxin type B (Neurobloc, Elan Pharma, Munich, Germany) to the arm amputation stumps, 5000 IU for one amputation of the lower leg, and 2500 IU to the other lower leg amputation of a patient with a very low baseline body weight. Two patients reported that the injection was very painful. All patients experienced a reduction in stump pain, which lasted for many weeks. Other reports included a reduction in the frequency of pain attacks, cessation of "balloon feelings," improvement in stump allodynia, and decreased occurrence of involuntary stump movements. In addition, quality of sleep at night significantly improved in one patient. Botulinum toxin type B can therefore be regarded as a new treatment option for possible improvements in the rehabilitation of amputees.

The synthesis and acidic properties of polymers of 5-vinyltetrazole and 5-isopropenyltetrazole are described. The results show that the behaviour of these polymers in solution is determined by both hydrogen bonds with participation of tetrazolic cycles and by hydrophobic interactions between monomer residues


A great number of micro electro mechanical (MEM) devices have been developed during the last decade. The fabrication of such devices is usually based in some kuid of surface micromachining technology, in which supporting sacrificial layers are removed to free the niicromechanical structures. Due to its technological compatibility with standard IC processing, polycrystalline silicon has been used as the device material for MEM devices such as beams [ 11, pin joints, cranks and sliders (21, gears [3], electrostatic micromotors [4] and electrostatic combdriven structures [SI. The standard chemical vapor deposition method for polysilicon limits the thickness of the microstructures to a few microns. However, for many kinds of microstructures a greater thickness is beneficial. These would include devices with its motion constrained to the plane parallel to the substrate. In that case the increased thickness increases the stiffness of the device in the direction perpendicular to the plane of motion. Also, for devices that use electrostatic attraction between sidewalls as the driving force, such as comb actuators aid micromotors, the increased thickness allows a greater driving power for a given voltage.


The equipment for measuring electron beam (EB) focus in electron beam produced by the effect of extremum temperature of powder molten pool caused by the interactive effect of electron beam with metal powder is described. The principle of operation of apparatus and examples of EB characteristics are presented. During electron beam processing, the mechanical analysis of metal powder molten pool temperature following focusing current are studied. As a result, the transferring point of critical energy density described by the peak of metal powder pool temperature can be obtained. Based on the temperature characteristics of critical energy density, the measuring concept of dynamic focal spot of electron beam is put forward in the paper. The method of measuring dynamic focal spot of electron beam will provide a new possibility for 3D scanning prototyping through changing focus position of EB.


This study aims to investigate the predictability of a friction-induced nonlinear dynamic behavior on a simplified yet controlled laboratory experiment through the fuzzy logic approach. First, a mass-sliding belt experiment is built to observe the effects of several operating parameters on the occurrence of nonlinear dynamic behavior. Second, experiments are performed at various levels of these operating parameter, and the data are recorded. Third, fuzzy logic model architectures with different membership functions are built, where these operating parameters are assumed as the input parameters. The output of the fuzzy logic model architecture is defined as a new parameter called squeal index. Finally, a fuzzy logic model with a 96.97% prediction accuracy is obtained. Hence, it is shown that the proposed model can provide insight about the dynamic behavior of the system of interest without solving the nonlinear governing equations. Furthermore, the proposed model allows the prediction of the system state at operating conditions where experimentation is not possible, and it can be used for the determination of the critical operating parameters at which the system behavior switches from one state to another.

Abstract:
 The habitat of Osmoderma eremita, a European endangered beetle species restricted to tree cavities, was examined in central Italy, at the southernmost limit of its distributional range. The occurrence of adults, larvae, and fragments was investigated in 170 and 151 living hollow trees by pitfall trapping and sampling of wood mould (i.e., loose material) in the hollow, respectively. Overall, O. eremita was present in 22% of the trees, which belonged to 4 different tree species (Ostrya carpinifolia, Quercus suber, Acer obtusatum, and Quercus pubescens). The frequency of presence was higher in cavities with more than 4 L of wood mould, in cavities with dry or half-moist wood mould rather than wet wood mould, and with wood mould with low soil contamination. A comparison with northern regions indicated that the warmer macro-climatic conditions in the south make the species independent of a warm microclimate. As most of the hollow trees contain only a small amount of wood mould (<4 L), the habitat quality is generally poorer than in oak pastures studied in northern Europe.


Background and Objectives  An international collaborative study was undertaken to identify a replacement for the World Health Organization (WHO) 1st International Standard for human immunodeficiency virus 1 (HIV‐1) RNA for use in nucleic acid‐based techniques (NAT) (code 97/656). In the original study to establish the 1st International Standard, a second candidate material (code 97/650) had been shown to perform well and this was re‐evaluated to establish whether it would be a suitable replacement.


A series of new waterborne polyurethane (WPU)/cellulose nanocrystal (CN) composites have been successfully synthesized viain situpolymerization. The conditions were optimized to induce the grafting of part of the pre-synthesized WPU chains on the surface of cellulose nanocrystals (CNs) and the corresponding nanocomposites were processed by casting and evaporation. The morphology, structural, thermal, and mechanical properties of the resulting nanocomposite films were evaluated by scanning electron microscopy, wide-angle X-ray diffraction, differential scanning calorimetry, dynamic mechanical analysis, and tensile tests. The success of the grafting was substantiated by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and differential scanning calorimetry. Thus, it was demonstrated that the grafted WPU chains formed crystalline domains on the surface of CNs which expedited the crystallization of the polycaprolactone (PCL) soft segment domains in the WPU/CN nanocomposites. This co-crystallization phenomenon induced the formation of a co-continuous phase between the matrix and filler which significantly enhanced the interfacial adhesion and consequently contributed to an improvement in the thermal stability and mechanical strength of the nanocomposites. Although the ductility of the final nanocomposites was slightly reduced, in the CN content range from 0 to 10 wt-%, the Young's modulus and strength were significantly improved as shown by the change from 1.7 to 107.4 MPa and 4.4 to 9.7 MPa, respectively.


Object detection is a basic task in the field of computer vision and is widely used in various fields. However, there is also low detection performance caused by object scale changes and low feature extraction capabilities of the network, which makes the utilization of multi-scale features low. Therefore, this paper proposes a method based on dense connection and feature fusion. In this method, a dense connection module is designed to improve the ability of the network to extract features and improve the utilization of multi-scale features; a feature fusion module is designed to integrate feature information. In addition, The loss function uses Focal loss as classification loss and GIoU as positioning loss. The Tensorflow deep learning framework is used to deploy the network, and experiments are conducted on the VOC2007 and 2012 data sets to verify the effectiveness of the proposed method and compare it with the current method.


Cloud detection is an important task in meteorological application. Cloud information is especially important for now-casting purposes (1) and as an input for different satellite based estimation of atmospheric and surface parameters (2-4). The solar energy is the principal source of energy in the solar system. Clouds have high reflectance and absorption property which is used to distinguish them with land, water or sea area. There is critical demand to develop application, which can calculate the presence of cloud by using the available satellite image processing data, so that prediction of radiated solar energy can be optimised and energy budget can be predicted more easily.


". . .Modernity is a double-edged phenomenon. While its core values have a liberating potential, its concrete practices may cause arrogance and violence. It is like being excessively proud of oneself, and looking at others with a sense of contempt. I am rational, modern, and enlightened; you are ignorant, superstitious and barbaric. It is like dividing and hierarchising the world. If we look at history, we notice this arrogance of modernity particularly, the hyper-modernity of the West" (p.26).


Radial Basis Functions are a modern way of creating a regression model of a multivariate function when sampled data points are not uniformly distributed in a perfect grid. Radial Basis Functions are well suited to atmospheric characterization when unmanned aerial vehicles (UAVs) are used to sample the given space. Multiple UAVs reduce the time for the Radial Basis Functions to yield a suitable solution to the measured data while data from all aircraft are aggregated and sent to Radial Basis Functions to fit the data. The research presented here focuses on the requirements for a high correlation value between the sampled data and the actual data. It is found that the number of centers is a large driver of the goodness of fit in the Radial Basis Function routine, much like aliasing is an issue in sampling a sinusoidal function. These centers act like a sampling rate for the spatially varying wind field. If the centers are dense enough to fully capture the spatial frequency of the wind field, the Radial Basis Functions will produce a suitable fit. This also requires the number of data points to be larger than the number of centers. The ratio between the number of centers and number of sampled data points declines as the number of centers increases. The results presented here are revealed using a two-dimensional Fourier series analysis coupled to a spatially varying atmospheric wind model and a Radial Basis Function regression model.


Yellow and blue Pantone colors were printed on a substrate with high Optical Brightening Agent (OBA) levels and then measured under different measurement condjtions as outlined in ISO 13655. Both colors exhibited large DEOO shifts with lighter screen tints, as more paper influenced the measurement. The Paotooe colors were further analysed after being printed on two different substrates with varying OBAs. While the solids were color-matched to a DEOO of less than 1.0, the tints resulted in DEOO values above 7.0 due to more paper influence in the lighter screen tints.

To solve the online real-time diagnosis problem of the nuclear power plant in operating condition,a method based on a combined artificial neural network is put forward in the paper.Its main principle is: using the BP neural network for the fast group diagnosis,and then using the RBF neural network for distinguishing and verifying the diagnostic result.The accuracy of the method is verified using the simulation values of the key parameters in normal status and malfunction status of a nuclear power plant.The results show that the method combining the advantages of the two neural networks can not only diagnose the learned faults in similar power level of the nuclear power plant quickly and accurately,but also can identify the faults in different power status,as well as the unlearned faults.The outputs of the diagnosis system are in form of the reliability of the faults,and are changing with the lasting of the operation time of the plant.This makes the diagnosis results be more acceptable to operators.


With current technology, the resist lithography can be implemented to fabricate microstructures with high-aspect-ratio geometries. In this work, arrays of SU-8 photoresist pillars (10×10×50 microns) on a copper substrate were patterned by X-ray (wavelength 1.24 nm) from a synchrotron source. Pattern defined silver dots on a graphite mask partially covered the substrate exposed to the X-ray. After the resist developing, the chemically stable and mechanically hardened SU-8 pillars can be used for subsequent magnetic depositions in spite of incomplete pattern in some areas of the substrate.


Abstract : Software tools are now available to assist the Air and Space Operations Center (AOC) with effects based Course of Action (COA) development, analysis, comparison and selection. In 2001, the Information Directorate of the Air Force Research Laboratory (AFRL) initiated an advanced technology demonstration program in the area of effects based operations. The program set out to develop new concepts and a software toolset to meet the AOC requirement for effects based targeting and campaign assessment. At the core of the toolset are the Strategy Development Tool (SDT) and Causal Analysis Tool (CAT). The Strategy Development Tool guides the user through the development of effects based COAs. During the initial planning phase, the Causal Analysis Tool predicts the probability of achieving commander's intent for the effects based COAs. During execution, the Causal Analysis Tool acts as a campaign assessment tool by incorporating accrued evidence provided by a multi-intelligence fusion component. An attrition-based campaign level wargaming tool was also developed to supplement COA analysis The goal is to transition the software tools to AOC strategists to help them achieve an effects based approach to the COA development process described in Joint Publication 3-30, Command and Control for Joint Air Operations. Though focused on air operations, the tools can be used at the Joint Force Command level as well.

Over the last few years, there has been an exponential rise in the trend to use mobile devices within enterprises. Organizations and employees are using their smart phones and tablets to aid in work. Several organizations has introduced the concept of "bring your own device" (BYOD), in order to achieve more efficiency and improved productivity. This increase in use of mobile devices, although providing benefits to the organizations, is also resulting in more effort for the information technology (IT) staff to provide support and manage these devices within the enterprise. Several organizations around the globe are implementing mobile device management (MDM) / enterprise mobility management (EMM) solutions to manage mobile devices within the organization. This study identifies the prospects and challenges in implementing EMM using a case of a large telecom service provider in United Arab Emirates (UAE).


In Congress last spring, several Democratic senators and representatives introduced the Seniors Safety Act of 1999, which proposed, in part, measures making it easier for the federal government to prosecute healthcare fraud cases. About the same time, Vice President Gore announced the administration's creation of a new national healthcare fraud and abuse task force and vowed to increase the government's efforts to prosecute healthcare fraud cases. President Clinton recently used his weekly radio address to the nation to trumpet his administration's successes in combating healthcare fraud, telling the American people that "when it comes to prosecuting fraud and abuse, we're doing more than filing cases; we're also winning convictions."

The role of the carotid body (CB) as a primary chemosensor is well established in large mammals. Due to our ability to better modify the genome the mouse has been used for hypoxic chemosensing research. The only method by which one can study the global and unified CB response to hypoxia is via recording the carotid sinus nerve (CSN) activity. Our laboratory has been using the two inbred strains of mice, DBA/2J and A/J. In general, the DBA/2J is more sensitive, with an elevated cardiorespiratory response to hypoxia compared to the A/J strain. Thus, the purpose of this study is to establish a stable in vivo model for recording CSN activity in these two strains of mice. CSN activity was recorded from the central end just prior to its junction to the glossopharyngeal nerve using a glass suction pipette in six DBA/2J and A/J mice. Baroreceptor activity was mechanically disrupted. Following a baseline recording, the inspired gases were changed from hyperoxia to FIO2=0.21, 0.15 and 0.10. CSN activity was then analyzed using Fast Fourier Transform (FFT) based time‐frequency spectral analysis. The data showed a hyperbolic relationship between PO2 and CSN activity in the DBA/2J mice. The A/J mice showed a significant attenuation in their carotid body neural output when compared to the DBA/2J mouse at all comparable levels of normoxia and hypoxia. Thus, the model established methods to examine carotid body responses to hypoxia in mice and showed a clear difference in the carotid body generated neural output in the DBA/2J mouse when compared to the A/J. This model can now be used to study how the different genetic make‐up, by using other strains and knockouts, can alter the overall in‐vivo response to hypoxia.

Jiaxing's agriculture will be faced with great influence and impact after China's entering WTO. Meanwhile, the entry to WTO also brings some opportunities for Jiaxing to adjust the agricultural structures and accelerate the agricultural development. So we must take the opportunities and meet the challenges to increase the competitive power of the agricultural produce in the world market.


ABSTRACT A study was conducted in Bahia Kino, Sonora, northwestern Mexico, to evaluate the feasibility of alternate culture of white shrimp, Litopenaeus vannamei, and yellowleg shrimp, Farafantepenaeus californiensis, during the summer-fall and fall-winter seasons, respectively. Two stocking densities (20 and 30 shrimp/m2) were evaluated for both species. Results demonstrated that the alternate culture of these two species is feasible and that the culture of yellowleg shrimp did not seem negatively affected by the previous culture of white shrimp, in aspects such as transmission of pathogens or deterioration of water quality. Growth rate (0.88-1.02 g/week), survival (66.7%-77.8%), and yield (2208-2462 kg/ha) of white shrimp were comparable to those reported for most commercial semi-intensive farms. For yellowleg shrimp, during the fall-winter season, the three parameters were lower (0.52-0.44 g/week; 50.2%-52.1%; and 1,260-1,536 kg/ha, respectively). Growth and survival rates of both species were higher a...


Permanent magnet compounds are basically ferromagnets with uniaxial anisotropy. In different cases, the magnets are elaborated by sintering of powders previously oriented and compressed under field. The value of the remanent induction Br is directly dependent on the degree of crystallites alignment, and we present in this paper two different quantitative methods to determine it. X-ray analysis involves the comparison of the intensities of Bragg reflections, for different values of the angle of a direction [hkl] with respect to the unique crystallographic axis of the compound. Magnetic analysis involves the comparison between experimental magnetization curves and calculated ones for different statistical distributions of crystallites orientations. Both methods were applied to NdFeB and SmCo5 magnets. They reveal that the misorientation of particles in these systems leads to a reduction of the remanent induction by about 10 %.


The effect of washing on electrochemical properties of Ni-rich layered cathode LiNi0.8Co0.15Al0.05O2 powder is widely known, but few literatures have reported thoroughly. Primitive LiNi0.8Co0.15Al0.05O2 powders processed by deionized water and heat-treatment at different temperatures in a paralleling time was explored for the first time. Sig- nificant changes of structure, morphology and electrochemical charge/discharge property of the LiNi0.8Co0.15Al0.05O2 cathode were detected comprehensively. Mechanism of washing and heat-treatment on the structure and electrochemi- cal charge/discharge property and the rate performance were studied. XRD patterns show the I(003)/I(104) value of LiNi0.8Co0.15Al0.05O2 powders decreases and the volume turns smaller after being washed and heat-treated. FT-IR spec- tra confirm the existence of lithium carbonate, and nickel compounds and their relative changes in the LiNi0.8Co0.15Al0.05O2 powders. The specific capacity and rate performance of the LiNi0.8Co0.15Al0.05O2 powders were carried out before and after washing and heat-treatment. The capacities of primitive sample and treated samples remain 88.87%, 87.21%, 85.43% and 87.80% after 30 cycles, respectively.


This study investigated the variation in density of macular pigment across the central retina in normal and albino subjects.

Self‐regulatory companies have the most successful record, and the five major characteristics of these are examined in detail. Examples of corporate disasters are provided to illustrate the risks of ignoring the message of this article.


The primary goal of this ultra low-power transceiver IC project is to realize an innovative integrated transceiver front-end. It is designed and developed for low bit rate data transfer for general consumer applications and consumes very little power. Introduction Many applications and Wireless Personal Area Network (WPAN) nodes in the ambient intelligent home of the future would require only low bit-rates (only a few bps up to 1 kbps). LP/LBR (Low power/low bit-rate) RF transceivers require a new architectural approach, compared to moderate and high-speed multi-media wireless link, in order to prolong the battery lifetime and thus minimize battery replacement for the consumers [1]. In the future, it is envisaged that ultra low-power RF transceivers may not need any battery pack, as it can extract all needed energy from the environment, to power up an IC chip for low bit-rate applications. Therefore, this project aims to develop a system-on-chip (SoC) comprising a low-power RF front-end architecture, a FSK/GFSK modem, and an 32-bit microcontroller from Infineon. In order to achieve ultra low-power consumption, the subthreshold design concept will be employed in the RF front-end. In addition, a high level of integration is necessary to reduce the cost of the


To control the rutting resistance of a semi-rigid-base asphalt pavement under different traffic volumes, a rutting test is conducted to simulate the actual pavement internal temperature field on full-depth asphalt surface course samples excavated from different sections (different corresponding traffic volumes) and rutting depths in an expressway reconstruction and extension project. The relationship between dynamic stability and rutting depth on the main lane is analyzed. The dynamic stability control criteria, which are dynamic stabilities corresponding to 15 mm rut depth, to fit the traffic volumes of different sections are determined. The accumulative equivalent axles of different sections are collected and calculated. The relationship between the dynamic stability control criterion of each section and its accumulative equivalent axle is analyzed to obtain a fitting equation. A dynamic stability control criterion for the asphalt pavement structure at heavy traffic level is suggested based on this fitting equation. Afterward, a method of determining the dynamic stability control criterion for the entire asphalt surface course under different traffic volumes is recommended.


Abstract. Due to the influence of typhoon "fireworks" on July 20, 2021, there was a rare heavy rainfall in Zhengzhou, Henan Province, China, which caused severe urban waterlogged disasters and casualties. Take it as an example, using Web Crawler technology to obtain Weibo's (Chinese Twitter) time and space data involved in the rare heavy rainfall in Zhengzhou. Through statistical analysis and spatiotemporal analysis to filter, classify, analyse and manipulate the crawled Weibo's data, and then study the influence of the extreme rainstorm weather on the traffic areas from two aspects of address points and road networks. At the same time, to verify the effectiveness of the social media-based method for mining the traffic impact areas of the Zhengzhou extreme rainstorm, this experiment compares Weibo data with official data in various aspects according to four categories of waterlogging severity.

In this paper, we examine several algorithms suitable for the hardware implementation of the discrete Fourier transform (DFT) with non-power-of two problem size. We incorporate these algorithms into Spiral, a tool capable of automatically generating corresponding hardware implementations. We discuss how each algorithm can be used to generate different types of hardware structures, and we demonstrate that our tool is able to produce hardware implementations of non-power-of-two sized DFTs over a wide range of cost/performance tradeoff points.


The enchantment with Mapungubwe gold has marginalised mundane artefacts such as crucibles, which basically are domestic pottery used in metallurgical operations. The only distinction is that crucibles contain occluded slag in the interior, with occasional cuprous prills. In the ethnography, metallurgy and pottery making are characterised by gender exclusivity – men are metalworkers while women are potters. Taboos prohibit men from potting while a set of cultural restrictions also prevented women from metalworking. The presence of typical female material culture pottery in a male domain (metalworking) at Mapungubwe therefore requires further investigation to shed new light on gender relations in southern African pre-colonial metallurgy. For example, were the crucibles and pottery made of the same clay? Furthermore, is the technology of production similar or different? Who made crucibles and who made pottery? Also, what metals were worked and processed in the crucibles? Answers to these questions require a dedicated inter-disciplinary study crucible and domestic pottery fabric to explore technological and decision making choices invested by the manufacturers of these macroscopically identical material culture items. This proposal seeks to study ten samples of crucible fragments and ten samples of domestic pottery from Mapungubwe that are currently in the UCT collection. After study, the materials will be returned to the Mapungubwe Museum in Pretoria. It is hoped that a paper will be produced for a top journal such as the Journal of Anthropological Archaeology.


Most State ground-water programs can be grouped under three headings: basic data collection, answering requests, and research and report writing. In Ohio the staff consists of four geologists, two hydrologists, and one field inspector. Most time is spent collecting basic data and answering requests for assistance.

(1) Basic data collection: It is the responsibility of one hydrologist to maintain and coordinate the 150 State observation wells. The field inspector is responsible for seeing that well logs are submitted by well drillers in accordance with State law. The inspector is a geologist who works closely with the drillers; he is also active in the Ohio Well -Drillers Association, and prepares a quarterly newsletter. A highly organized well-log file system is maintained, and there is a field location program whereby well locations are plotted on large-scale maps. A ground-water quality sampling program is in operation. A network of 20 existing production wells in strategic areas was established for observing seasonal and annual changes in ground-water quality. A monthly summary of water-supply conditions across the Scace is published.

(2) Answering requests: Of the 2,000 requests answered each year, approximately 80 percent involve domestic wells. The remaining inquiries are from industries, municipalities, schools, developers, State agencies, and various commercial or recreational interests. In answering requests a report summarizing hydrogeology and ground-water availability is prepared. For large ground-water developments that are not State-financed the services of a consultant are recommended.

(3) Research: Much research in the public interest is concerned with problems and potential problems in ground-water pollution.


The driving range of electric vehicle can be significantly reduced if using CO2 as a refrigerant in hot climates. This paper aims to improve the performance of CO2 electric vehicle air conditioning system by using a dedicated propane mechanical subcooling, the interference between internal heat exchanger (IHX) and mechanical subcooling (MS) was discussed, since both improvements compete towards reducing the throttling losses, optimization possibilities were theoretically analyzed on several integrated system for various subcooling degrees from 3°C to 15°C and ambient temperatures from 25°C to 40°C, results show that the presence of mechanical subcooling after IHX reduces its efficiency, the use of mechanical subcooling simultaneously before IHX rather yields a more efficient air conditioning system. It has been shown that compared with CO2 prototype system, the new best integrated system can improve the COP (coefficient of performance) up to a maximum of 25.72% despite the extra compression work in mechanical subcooling cycle, and the cooling capacity up to a maximum of 46.24% during the research range, thus, the driving range of EVs can be significantly extended. Furthermore, the suitable cooling capacity and propane compressor displacement required in the MS cycle are predicted. Finally, experiments were carried out to see the actual improvements achieved by MS and IHX cycle based on the theoretical results.

The ordinary semiconductor diode displays unusual properties at high frequencies. It is observed that at high frequencies the rectification changes polarity. The phenomenon is explainable by short-duration carrier multiplication; the result being that more charge is reclaimable than is stored. This is seen as a negative resistance; i.e. when the diode is driven by high frequencies, it becomes active and can amplify, oscillate or switch.

Hate speech detection has emerged as a critical research area in recent years due to the rise of online social platforms and the proliferation of harmful content targeting individuals or specific groups.This task highlights the importance of detecting hate speech in text-embedded images.By leveraging deep learning models,this research aims to uncover the connection between hate speech and the entities it targets.


Conventional parameter designs of two-stage grid-connected photovoltaic (PV) system relied on its mathematical model of the cascade structure (CS), but the procedure is excessively cumbersome to implement. Besides, for a two-stage converter system, the coupling interaction between the power converters can directly lead to a poor parameter design. To overcome this drawback, this paper uses a simplified structure (SS) of single-phase two-stage grid-connected PV system to better design the parameters of the front-stage dc-dc converter. After establishing the small-signal model for SS and CS in the PV system, the relative eigenvalue sensitivity is used as the criterion for judging the influence of some parameters on the stability of the two structures. The stable boundary of MPPT control parameters is compared and discussed in SS and CS, respectively. In addition, the relationship between the front-stage dc-dc converter and the rear-stage dc-ac inverter is analyzed by the modal participation factor calculated in CS. An experiment is also performed at the end of this paper to further verify the feasibility of using SS to design the parameters of the dc-dc converter in the PV system.


Strapák P., Strapáková E., Rušinová M., Szencziová I. (2017): The influence of milking on the teat canal of dairy cows determined by ultrasonographic measurements. Czech J. Anim. Sci., 62, 75–81. The effect of milking on the length and diameter of the teat canal during teat regeneration immediately after milking was evaluated. The practical measurements of the teat canal were performed on 70 Holstein cows using ultrasound Aloka Prosound device 2. A special "bath method" of the teat ultrasonographic scanning was used at set time intervals – before milking, immediately after milking, and 30, 60, 90, and 120 min after milking. Before milking, the average length of the teat canal was 10.67 mm and 9.3 mm and the teat canal diameter was 1.11 mm and 1.09 mm for front and rear teats, respectively. The average length of the front and rear teat canal significantly increased by about 20.5 and 32.9% and the front and rear teat canal diameter increased by 9.0 and 9.1% on average immediately after milking compared to values detected before milking. After 120 min of regeneration the teat canal was by 3.56 and 14.95% longer than before milking for front and rear teats, respectively. Prolongation of the teat canal was significantly affected by teat position. Based on the present results, the time period of 120 min is not sufficient for the complete regeneration of the teat canal length to the pre-milking values. On the other hand, we recorded total regeneration of the teat diameter within 120 min after milking. The initial values of the front and rear teat diameter were equal to those measurd 120 min after milking.

Nowadays, simulation is essential when researching manufacturing process or designing production system. Line performance and equipment utilization are two major points of interest for every manufacturing company in order to increase competitiveness in the global market. The job shop scheduling is the allocation of a number of machines to perform a set of jobs. Job shop scheduling problem exists in most of the manufacturing systems in various form. Due to its high mix and low volume manufacturing environment, priority selecting among the jobs is challenging. This project is a real case study which involving a job shop with five similar CNC milling machines. A total of six jobs were performed and each of them consists of a different set of operation. The sequence of the six jobs to enter the system was determined by the sequencing rules including shortest setup time (SST), shortest processing time (SPT), shortest processing time + setup time (SPST), lowest volume (LV), least process (LP) and earliest due date (EDD). The setup time was taken into consideration to make the results more realistic. Due to the complexity of the model, WITNESS was used to simulate all the sequencing rules and the results are obtained. The best rules approach for the company in this study can be determined by comparing the results for each rule. By doing this, the company will be able to make faster and better decision about which job should be processed first instead of pick it randomly among the jobs. The results indicate that no single rule is excellent in all criteria. SPST rule was recommended to the company as it performed the best in terms of total completion time.


As a support component between spacecraft and antenna, the accuracy of cable-strut tensegrity mast is crucial to the task. In order to analyze the influence of manufacturing tolerance on its end accuracy, a static model of the mast is established by the force density method. The effects of strut tolerance and cable preload error on end position and pointing accuracy are analyzed based on the Monte Carlo method. Furthermore, the accuracy difference when the input error obeys uniform and normal distribution is further compared. The numerical results show that compared with the preload error, the strut length error has a more pronounced influence on the end accuracy.


Purpose

The authors investigate the 2008-2009 short-sales ban in Korea, one of the most comprehensive and restrictive short-selling bans worldwide. The purpose of this paper is to examine: whether the ban stopped a destabilizing effect, if there was any, of short-selling activities; whether the ban improved or deteriorated the informational efficiency or the price discovery process of the stock market; and whether the ban had any impact on market liquidity.

Design/methodology/approach

Multiple regression; vector autoregression analysis; and generalized autoregressive conditional heteroskedasticity analysis.

Findings

The authors find no evidence that short-sales have a market-destabilizing effect and thus, restricting short-selling has a market-stabilizing effect. On the contrary, the short-selling ban is associated with an increase in return volatility and a deterioration of the price discovery process, particularly for the stocks without derivatives traded on them. The authors also find evidence of a liquidity decrease for short-sale intensive stocks. However, the evidence is inconclusive as to whether the market efficiency and liquidity changes are solely the result of the short-sales ban or the compound effects of both the ban and the concurrent progress of the financial crisis.

Originality/value

The literature does not provide a conclusive view on the effects of short-sales or restrictions thereof on the stock market. Also, the existing research on recent worldwide shorting bans often lack empirical scope (e.g. 32 stocks for UK; three weeks for USA). In contrast, the short-sales ban in the Korean stock market, one of the most comprehensive and restrictive short-selling bans worldwide, lasted for eight months for all the listed stocks and is still in effect for financial stocks. The authors find no evidence that short-sales have a market-destabilizing effect and thus, restricting short-selling has a market-stabilizing effect.


This review addresses issues of various drift–diffusion and inhomogeneous advection problems with and without resetting on comblike structures. Both a Brownian diffusion search with drift and an inhomogeneous advection search on the comb structures are analyzed. The analytical results are verified by numerical simulations in terms of coupled Langevin equations for the comb structure. The subordination approach is one of the main technical methods used here, and we demonstrated how it can be effective in the study of various random search problems with and without resetting.


This article discusses the variant of Islam that lives in a multicultural society in the Sungai Ambawang area in the suburbs of Pontianak City, West Kalimantan. In the Javanese, Bugis, Malay and Madurese communities, Islam has served as an important element in the formation of their cultural identity, thus causing them to be synonymous with the Islamic community. Islamic elements that are used and have become part of the culture of society include the choice of Islamic dates such as the Hijri month in determining the time of cultural activities, the use of Al-fitihah and several other verses from the Qur'an as well as shalawat and prayer, the use of mosques as a center of cultural activities and the involvement of Islamic religious leaders in traditional ceremonies. The use of these elements has become a hallmark of the community culture and its form has been preserved until today.


Objective The purpose of this study was to evaluate the outcome following complete repair of tetralogy of Fallot(TOF) under one year of age. Methods 58 infants with TOF undergoing were completely repaired between January 1999 and August 2005 were reviewed. The concomitant lesion included atrial septal defect in 8 patients, patent ductus arteriosus in 3 patients and abnormal coronary arteries in 3 patients, Down's syndrome in 2 patients. 2 patients had a previous modified B-T shunt. The site of ventricular septal defect (VSD) was perimembranous in 56 patients and subarterial in 2. 2 patients had VSD repair with fenestration. Correction was accomplished through ventriculotomy (48 patients), atriotomy (4 patients) or transatrial-transventricular approach (6 patients). A transannular patch was inserted in 39 patients. Results The mean bypass and aortic cross-clamp time were 95. 5 and 53. 5 minutes respectively. The mean ventilation time, ICU stay and postoperative hospital stay were 30 hours, 4 days and 14 days respectively. Delayed sternum closure was performed in 3 patients. There were 2 early deaths (mortality 3. 4%) and no late death. Early postoperative complication included low cardiac output (5 patients), renal failure (4 patients), supraventricular, junctional ectopic tachycardia (2 patients), complete heart block (1 patient), etc. Follow-up was available from 3 months to 5 years postoperatively. All the patients alive were doing well with NYHA functional class I to I . Conclusions Early complete repair of TOF in infancy is associated with acceptable mortality and morbidity, as well as excellent heart function during early and mid-term follow-up. Elective complete repair of TOF under one year of age is recommended.


For a class of variational inequalities (quasilinear parabolic problems with a one-sided 'obstacle') arising from the Hamilton-Jacobi-Bellman formulation of certain periodic stochastic optimal control problems, it is shown that there are unique periodic solutions. AMS Subject Classification: 35B10, 49A29, 49C99.


The frequent items problem is to process a stream of items and find all items occurring more than a given fraction of the time. It is one of the most heavily studied problems in data stream algorithms, dating back to the 1980s. Many applications rely directly or indirectly on finding the frequent items, and implementations are in use in large scale industrial systems. Informally, given a sequence of items, the problem is simply to find those items which occur most frequently. Typically, this is formalized as finding all items whose frequency exceeds a specified fraction of the total number of items. Variations arise when the items are given weights, and further when these weights can also be negative.


Background and purpose: As one of the major types of programmed cell death (PCD), necrosis has been observed and demonstrated to be responsible for cell death and the mechanisms responsible for necrosis are still not very clear. This study reviews that programmed cell death (PCD), including apoptosis and necrosis for C6 glioma cells is related to p53-reactive oxygen species (ROS). Methods: The C6 glioma cells were treated with N-acetylcysteine (NAC) and assayed for cell survival, cellular ROS levels by flow cytometry assays, and western blot assay for p53 expression. C6 glioma cells were compared to downregulation of ROS levels and p53 expression, respectively pretreated with p-fifty three inhibitor-alpha (PFT-a) and N-acetylcysteine (NAC). Results: C6 glioma cells showed a significant decrease (~2-fold) in DHE-fluorescence after NAC treatment. Interestingly, the accumulation of ROS was elevated with p53 expression in C6 glioma cells. The increase in ROS levels was followed by a decrease in cell growth and viability, and increase in the percentage of cells with necrosis. Conclusions: p53 overexpression enhanced p53-induced ROS-accumulation, which was accompanied by an increase in cell death with necrosis. These results support the hypothesis that there is a close relationship between regulating p53-induced ROS-accumulation and apoptosis and necrosis in C6 glioma cells.


A novel resistance element welding technology was applied to join 6061 Al alloy and uncoated 22MnMoB boron steel. To conduct the resistance element welding process, a technological hole was drilled in the Al sheet into which a Q235 steel rivet was inserted. Resistance spot welding was carried out at the rivet. The mechanical properties, fracture morphology, nugget formation process, dynamic resistance, microstructure, and hardness distribution of the resistance element welding were investigated. Traditional resistance spot weld joints were also prepared for comparison. Resistance spot welding could barely join Al 6061 and boron steel, and had a maximum tensile shear force of less than 1000 N. Novel resistance element welding could join the metals reliably with a maximum tensile shear force of over 7000 N and a relatively high toughness. Nugget formed at the interface of rivet and steel acted as loading position, and IMC interlayer connected rivet and aluminum.


We study the magnetic domain pattern in a ferrimagnetic CoTb thin film using Lorentz transmission electron microscopy. The evolution of domain patterns is captured at different temperatures and external fields. Magnetic dipole skyrmions and bubbles can be created simultaneously by increasing the temperature of the sample and applying appropriate out-of-plane magnetic fields. By tuning the external magnetic fields, it is found that the skyrmions are annihilated at a higher magnetic field compared to bubbles. Moreover, we also find that the in-plane magnetic field influences the formation and the shape of skyrmions and bubbles. Further, micromagnetic simulations are also consistent with the experimental observations. Our findings provide insights into the magnetic field stability of skyrmions.

The history of the human race is closely interwoven with the history of disease. Paleopathological examination of fossil bones has clearly demonstrated the immense antiquity of disease, which reaches back into remote periods of the earth's history. For the peoples of antiquity it was a phenomenon of great personal and social significance, being uniformly associated with the operation of malignant spirits and demons. That this belief was common alike to savage and civilised man is clear from the vast amount of anthropological research of the last seventy-five years, as well as from the ancient texts which have been unearthed by the archaeologists. In the ancient world the office of the physician was generally the prerogative of the priesthood, and the numerous incantations which have survived on clay tablets and in manuscript form testify to the place which they held in medical function because of their supposed ability to meet disease at the spiritual level at which it was thought to originate. Particular service has been rendered by the archaeologist in uncovering for our benefit some of the treasures of Egypt and Mesopotamia, which present a picture of disease in a startlingly modern aspect. From 1867 in Egypt, numerous papyri were discovered which contained material of a medical nature, these documents being of particular importance because they drew upon sources which originated in the remote past. Of these the Edwin Smith papyrus, published by J. H. Breasted in 1930, is probably the most important because it shows that the priest-physicians paid attention to the diagnosis and treatment of ailments in a more rational and scientific manner than the common


Objectives Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide. We sought to identify the current definitions, prevalence, risk factors and preventive interventions for PPH. Methods We searched the National Guideline Clearinghouse, the Cochrane Library, PubMed and Ichushi Web beginning through November 2011. We performed a systematic literature review. After title and abstract screening, study quality was assessed. Results Blood loss from genital tract of 500mL or more in the first 24 hours after the delivery is defined as PPH. Recently in Japan, 800mL or more was diagnostic criteria for abnormal bleeding after vaginal delivery. Severe PPH was defined as 1000 mL or more and was more important in terms of maternal health. The prevalence of PPH, (blood loss over 1000 mL after vaginal delivery), in Japan was 2-5 %. Risk factors identified during pregnancy were: macrosomia, recurrence of PPH, multiple gestation, grandmultiparous (4 and more), maternal age over 35 years, low-lying placenta, polyhydramnios, antepartum hemorrhage, obesity (BMI is 25 and over), severe anemia, uterine myoma, and history of cesarean-section, PIH (Pregnancy Induced Hypertension), post-term delivery. Prolonged first and second stage labor, prolonged third stage labor, chorioamninitis, induction of labor, assisted delivery retained placenta, anomaly of the rotation, vaginal laceration and Kristeller maneuver were risk factors identified during delivery. Effective preventive interventions were active management strategies to promote uterine contractions in the third stage of labor; especially prophylactic uterotonics, nipple stimulation for induction of labor, breast feeding after the delivery of baby. Conclusions PPH is no longer unusual in Japan. It appears that some PPH cases are preventable by risk screening and preventive interventions. Based on the results of this literature review we should develop PPH prevention guidelines for midwives.


Diabetic neuropathy (DN) is one of the common complications of diabetes mellitus (DM), its incidence can be as high as over 90%. The lesion can involve the sensory, motor and vegetative nerves. As a whole, the lesion can be divided into symmetric multiple neuropathy and asymmetric single neuropathy. Because the pathogenesis of the disease is not clear, no specific therapy is available so far. Besides control of blood sugar level, vitamin B, vasodilators and analgesics are often used in Western medicine for expectant treatment. Basic studies on chronic complications of DM show that aldose reductase and non-enzymatic glycosylation of protein are factors initiating the pathological changes, inhibitors against them have been tested in experimental studies and proved effective. Unfortunately, they are not used clinically due to severe side effects. Screening for herbal drugs to treat DN is still a popular trend in the TCM circle.


There are several limitations in the application of the logistic financial rating theory, for example, it requires the continuous financial data to follow a logistic distribution, and the model has a problem of multicollinearity. In order to solve these problems, this paper used a new method by preprocessing the financial data with discretization before fitting the logistic model. 780 Chinese corporate bonds and 72 financial indices were used in the empirical study. Results show that a reasonable logistic model with not only less explanatory variables but also high prediction accuracy could be established in this way. Conclusively, this algorithm can provide an effective way to solve the restrictions and produce a more concise and reliable financial rating model by introducing discretization.


Bicycle sharing scheduling is a complex mathematical optimization problem, and it is challenging to design a general algorithm to solve it well due to the uncertainty of its influencing factors. This paper creatively establishes a new mathematical model to determine the appropriate number of vehicles to be placed at each placement point by calculating the traffic weights of the placement points and optimizes the hyperparameters in the algorithm by adaptive quantum genetic algorithm, and at the same time combines the network flow algorithm in graph theory to calculate the most suitable scheduling scheme for shared bicycles by establishing the minimum cost maximum flow network. Through experimental validation, the network flow-based algorithm proposed in this paper allows for a more convenient calculation of the daily bike-sharing scheduling scheme compared to previous algorithms. An adaptive quantum genetic algorithm optimizes the hyperparameters appearing in the algorithm. The experimental results show that the algorithm achieves good results as the transportation cost is only 1/15th of the GA algorithm and 1/9th of the QGA algorithm.

Objective To gain an insight into the mechanisms for endothelial monocyte-activating polypeptide-Ⅱ(EMAP-Ⅱ)-induced enhancement in the blood-tumor barrier(BTB) permeability.Methods Relatively pure cerebral microvessel fragments were obtained from the cortex of 3-5 days old wistar rats through carefully dissection,enzyme digestion,and dextran centrifugation.The fragments were then seeded on dishes and cultured primarily.In vitro BTB models were constructed by co-culture rat brain microvascular endothelial cells(BMEC) with C6 glioma cells.Confluent monolayers of co-cultured BMEC were randomly divided into 4 groups(each n = 6):control,EMAP-II,oligomycin and oligomycin + EMAP-Ⅱ groups.Transendothelial electric resistance values and horseradish peroxidase flux were measured to evaluate changes in the BTB permeability.The expression level of tight junction(TJ)-related protein ZO-1 in BMEC was measured by western blot assay.Double immunofluorescence was used to identify the expression and distribution of EMAP-Ⅱ and α-ATP synthase in BMEC.Results Compared with control and oligomycin groups,the BTB permeability of EMAP-II group was increased significantly(P 0.01),while the expression level of TJ-related protein ZO-1 was significantly decreased(P 0.01).These effects of EMAP-Ⅱ were significantly inhibited by pretreatment with oligomycin,the inhibitor of ATP synthase(P 0.01).Moreover,our data showed that both EMAP-Ⅱ and α-ATP synthase were expressed on the surface of BMEC.In addition,EMAP-II was found co-localized with α-ATP synthase.Conclusion EMAP-Ⅱ could increase the BTB permeability by opening TJ,and α-ATP synthase on the surface of BMEC might serve as the functional target.


A pelton turbine bucket is the individual component which makes up the turbine section of a pelton turbine. The blades are responsible for extracting energy from the high pressure water produced by the nozzle jet. The pelton buckets are often the limiting component of pelton turbines. To survive in this difficult environment, blades often use exotic materials In this project, pelton turbine bucket is designed and modelled in 3D modelling software CATIA V5. We know that the efficiency is directly related to material performance making the material selection of primary importance. In this project, materials considered for turbine blade are steel, cast iron and fiber glass reinforced plastic. Optimization is done by varying these materials by performing coupled field analysis on the turbine blade for both the designs. The objective of this project is to perform coupled field analysis of pelton wheel bucket for various materials and varying the number of buckets on the pelton wheel for finding out the efficiency, high stress handling factors.


Introduction: The great majority of clinical data that have been reported are related to the effect of low-intensity pulsed ultrasound (LIPUS) on the healing of fresh fractures. Objective: The aim of this study was to investigate compliance with LIPUS treatment for fresh fractures. Methods: The subjects were 94 patients (average age at the time of surgery was 56.4 years) who were given the LIPUS after the surgical operation for fresh fractures conducted between 2008 and 2013. We have defined LIPUS compliance rate (Number of days during which LIPUS was actually used / Number of days during which LIPUS was rented × 100). We have evaluated that LIPUS execution rate after dividing into good group (LIPUS execution rate ≥ 80%) and poor group (<80%). Age, Number of days during which LIPUS was rented, and fracture site were compared in the 2 groups. To determine differences between the 2 groups, we performed Student t test for age and Number of days during which LIPUS was rented. Chi-square tests were used to determine associations with fracture site between the 2 groups. Results: Average LIPUS compliance rate was 79% (6.6–100%). Average number of days during which LIPUS was rented was 145.2 days (22–370 days). The bone union rate was 97.8%. The average age was significantly higher in the poor group (60.8 years) than in the good group (50.6 years) (P < 0.05). There was a statistically significant difference on the Number of days during which LIPUS was rented (P < 0.01) between the good group (119.2 days) and poor group (164.5 days). There was a significant correlation between the LIPUS compliance rate and fracture site (P < 0.01). And, there were more radius and tibia for the good group and more femur and humerus for the poor group. Conclusions: The present study suggests that compliance of LIPUS for fresh fractures was influenced by age, number of days rented the LIPUS, fracture site.


Congenital diaphragmatic hernia occurs when a portion of the fetal diaphragm is absent, allowing abdominal contents to enter the thorax, and is associated with impaired pulmonary development. Although overall mortality is near 30%, a mortality rate less than 15% may be possible by following a standardized multidisciplinary care plan. Fetal diagnosis and evaluation can improve coordination of care, but there is no clear role for fetal intervention. After birth, gentle ventilation with permissive hypercapnia supports the infant while minimizing lung injury. Appropriate cardiovascular support, treatment of pulmonary hypertension, and extracorporeal membrane oxygenation may benefit some patients. Timing of surgical repair depends on disease severity. All patients should have close follow-up after discharge.


The researchers seek to provide a Gamification model that will help children of Sri Lanka improve their oral hygiene habits, thereby acting as a change agent to influencing adults' behaviors to have good oral hygiene habits. The nature of the study was a multi-method due to its complexity. The study took place within 13 weeks, where data was longitudinally collected from 50 families in a natural environment. Both descriptive statistics and quantitative methods were used to analyze the data. Our findings suggest that expedient designs need to consider all four clusters, namely System Design, Challenges, Rewards, and Social Influences, as interdependencies among these clusters enable and amplify the effectiveness of Gamification. Our findings should be of particular interest since they generally show vast potential to motivate children through Gamification. Organizations should not see Gamification as a 'magic bullet' for end-user motivation but as a means that must be carefully and deliberately integrated into the model to support a motivational culture that would prompt sustainable behavior.


To become successful communicators, children must be sensitive to the clarity/ambiguity of language. Significant gains in children's ability to detect communicative ambiguity occur during the early school-age years. However, little is known about the cognitive abilities that support this development. Relations between cognitive flexibility and ambiguity detection were assessed in preschool- (4- to 5-years-old, n = 40) and school-age (6- to 7-years-old, n = 36) children. Children rated the quality of clues (unambiguous/ambiguous) to the location of hidden stimuli provided by a videotaped speaker. Cognitive flexibility was assessed through a task requiring children to sequentially sort toys. Both age groups rated ambiguous clues as less helpful than unambiguous clues; however, school-age children were better able to detect ambiguity. Cognitive flexibility was related to preschool (but not school-age) children's communicative ambiguity detection, when controlling for age and receptive language. Results suggest that cognitive flexibility may be particularly important for the initial development of ambiguity detection.


This paper proposes an elegant way of estimating retail productivity through a mathematical model inspired by FGLS multivariate linear regression, using the error equation obtained as a hidden variable estimator to be used as inferred efficiency. This methodology was applied to a dataset obtained from a leading ready-to-eat cereal (RTEC) manufacturer and demonstrated substantial results. Unlike conventional ordinary least squares (OLS) regressions, the proposed approach offers benchmarking information relative to the best-performing retailers, as opposed to the typical relative-to-average outcomes of regressions. Furthermore, in contrast to traditional data envelopment analysis (DEA), this methodology relies on the entire dataset to establish the efficiency index, thereby addressing limitations imposed by DEA and allowing for executive discretion and flexibility in the analysis.

Through wall tracking can be very helpful in the situations where the entering of a room or a building is considered hazardous and it is desired to inspect its interior from outside through the walls. In majority of such cases, the tracking of multiple moving targets is needed. The radar signal processing for this application has to deal with several supplementary tasks in comparison with a single target tracking. Their solution is included in the complex signal processing procedure introduced in this paper. The experimental results obtained by the real radar signal processing confirm good performance properties of the proposed procedure.


A detailed theory is presented of the second‐order nonlinear optical interaction in a sequence of crystal lamellae oriented to give quasi‐phase‐matching. The efficiency of second‐harmonic and sum‐frequency generation is analyzed with respect to the orientation of the crystal axes, plate thickness, input intensities, transmission coefficients, dispersion in the intervening medium, and number of lamellae. An energy conserving modification of the small‐signal approximation is introduced. To overcome the Fresnel reflection losses the use of antireflection coatings, optical contacting, and Brewster‐angle incidence is considered with the latter approach emerging as the most promising. A series of experiments are described where 10.6‐μ laser radiation is frequency doubled in a sequence of GaAs plates using Brewster‐angle incidence. The conversion efficiency is investigated as a function of crystal orientation, intensity, and number of plates, and good agreement is found between theory and experiment.


First‐ and second‐ generation new treatments are being evaluated to provide a cure for hepatitis B. The life cycle of HBV includes several well‐ categorized steps that are targets for new treatments. A cure remains a major challenge even if it is measured by HBsAg seroclearance alone. The notion of a functional cure of hepatitis B has been accepted, while a partial functional cure has been more tentatively defined as a decline in HBsAg concentrations to lower levels after finite treatment.


Purpose
Job crafting is recently argued to have five dimensions (Nielsen et al., 2017): increasing challenging demands, decreasing social demands, increasing social job resources, increasing quantitative demands and decreasing hindrance demands. The purpose of this study aimed to investigate the psychometric properties and construct validity of the five-factor model of job crafting, introduced by using a sample of Jordanian university employees.

Design/methodology/approach
A pre-determined survey on was used. Accordingly, 513 professional workers in several universities completed the survey. Cronbach's alpha was used to assess the internal consistency of the scale, whereas series of confirmatory factor (CFA) analysis and exploratory factor analysis (EFA) were conducted to assess the scale's factorial and discriminant validity. Other tests were also conducted.

Findings
As predicted, the proposed model best fit the data. Statistical analysis yielded several findings. First, the results of the reliability test revealed that the five sub-scales of job crafting had significant and sufficiently strong internal consistencies. Second, the results showed that the 15 items loaded significantly with a factor loadings more than 0.50. Third, the CFA results confirmed that the five-factor model best fitted the data in comparison to the one-factor model. Finally, the construct validity of JCRQ-15 was confirmed through its correlation with several validating variables.

Research limitations/implications
Some limitations need to be addressed. First, the sample came from participants working in specific Jordanian universities which may limit the generalization that could be made from the results to other occupations. Second, due to the cross-sectional design of the present study, the question remains whether the JCRQ-15 are stable overtime. Third, the common methods bias might be a problem because it is one of the main sources of measurement error in validation studies using self-reported scales.

Originality/value
The present study provided an early supportive evidence for the use of the JCRQ-15 as a valid measure of job crafting in the Jordanian context.

ABSTRACT This paper presents an innovative approach in line commutated converter-based high-voltage direct-current (LCC-HVDC) transmission line for recognizing the section of the faults. In this work, three adaptive neuro-fuzzy inference system (ANFIS) modules have been suggested to investigate the safety responsibilities in the LCC-HVDC line. The ANFIS-1 aims to ascertain the faults in both sections; ANFIS-2 is to distinguish the section of the fault; and ANFIS-3 is to recognize the characteristics of the fault. To ascertain the effectiveness of the ANFIS approach, it has been compared with the differential protection (DP), wavelet transform (WT), fuzzy and artificial neural network (ANN). Furthermore, the proposed methods have been tested by varying the fault resistance (up to 500 Ω), power angle (from 5 to 15 degrees), near and end faults, and changing the transmission line parameters (±15 %). The simulation outcomes are disclosed that the proposed ANFIS technique yields better performance than other studied methods in terms of percentage of accuracy, time of fault section recognition, and reach setting.


The tinting phenomena of iron oxide containing glass have been specially and substantially investigated from aspects of electronic shell of the ions,the coordination field and the glass structure in this paper. The results reveal the innate character of iron ion tinting in glass, which is in contrast to ordinary standpoint. Tinting mechanism of several iron ions at different redox conditions and their influent factors have been investigated and some reasonable explanations have been proposed. The results show that the Fe~(3+)-O-Fe~(2+ )structure is the real tinting reason of iron containing glass.


The estimation of continuous soil moisture is critical for hydrological and agricultural study. The Land Data Assimilation System developed at the University of Tokyo (LDAS-UT) can estimate high temporal and spatial resolution. LDAS-UT was applied to the Pursat station which located near the Tonle Sap lake in Cambodia. The result showed that the low frequency of brightness temperature at the Pursat station was affected by the Tonle Sap lake area. To overcome this issue, we focused on the heterogeneity in the footprint, especially the existence of water bodies. We developed a water surface detection method to estimate water coverage within the low frequency data, and applied brightness temperature correction to remove effect of water body. Then, the corrected data was used with LDAS-UT to estimate soil moisture. The estimated soil moisture was in good agreement in dry season, and it can estimate low soil moisture value and increase accompany with precipitation during wet season.


Objective To study the velocity variation of four cardiac valves during natural respiration to research the mechanism and clinical importance of natural respiration on cardiac function in the patients with chronic obstructive pulmonary disease(COPD). Methods Pulsed-wave Doppler spectra of all four cardiac valves were recorded by Acuson Sequoia 512 in 20 COPD patients and 30 normal control subjects. Electrocardiogram and respiratory tracing by a nasal thermistor were recorded simultaneously. And then the respiratory variation indices (RVI) of the four cardiac valves were calculated. Results During natural inspiration, the peak E velocity of mitral valve and the velocity of aortic valve significantly decreased( P 0.001 ). On the contrary,the peak flow velocity across the pulmonary valve and E flow velocity across the tricuspid valve increased during inspiration( P 0.001 ).The RVI of the four cardiac valves in COPD group were significantly higher than that in normal subjects [mitral valve: ( 16.26 ± 8.71 )% vs ( 10.53 ± 3.15 )%, P 0.03 ; aortic valve: ( 11.61 ± 4.96 )% vs ( 4.67 ± 1.79 )%, P 0.001 ; tricuspid valve:( 27.74 ± 8.39 )% vs ( 14.89 ± 6.32 )%, P 0.001 ; pulmonary valve: ( 13.78 ± 4.98 )% vs ( 8.55 ± 2.32 )%, P 0.001 ]. Conclusions The rules in velocity variation of the four cardiac valves during natural respiration in COPD group and normal subjects were identical, but the RVI of four cardiac valves in COPD group was significantly higher than that in normal group. This further proved that the respiratory intrathoracic pressure change is one of the reasons that induce the respiratory changes of velocity across cardiac valve. These results have favorable reference values in differentiating of the severity of pulmonary parenchyma trauma and the follow up of the curative effects.


Autonomous measurement with NDT system like thermography on a large aircraft component (e.g. fuselage sections) is
a major challenge for standard industry robot. Many factors may affect the absolute positioning accuracy of created robot
TCP positions. 0.1° absolute robot inaccuracy (TCP) can cause for 1 meter working distance up to 3mm position error.
Another major drawback of thermography system is that certified examiners evaluate every 2D thermography image per
measuring field one by one. This unhandy and less intuitive method for large number of numerical data is inappropriate
for industrial applications. There are plenty of existing methods and technologies like Stereo vision method, using 3D
feature or multi-view method for 3D texture mapping. These methods require either a second camera or time consuming
additional processes or several images from every single measuring field.
This paper introduces development of a prototype robot based thermography measuring system and a new
method for 3D evaluation along with visualization of thermography results, which minimizes drawbacks described above.
Evaluation in 3D components coordinate, gives complex but complete 3D defect propagation knowledge. DLR-AQP
department is working on two different methods to calculate 2D-3D camera projection parameters. Method one projects
predefined 3D points per measuring field by using laser projector and applies 2D-3D point correspondence algorithm.
The second Method uses robot position and applies kinematic-coordinate-relationships algorithm. For both methods
single thermal image is captured by using thermography camera, which is also used for NDT. The first method is
applicable in laboratories as well as in production with and without any manipulator. This method enables also
contactless localization of detected defects. The second method requires robot. About accuracy, reproducibility and
flexibility of both methods have been compared and discussed in this paper. The 3D results are to be imported directly
into the CAD environment for further structure analysis.


Threats towards information systems have continued to increase and become more sophisticated, making security approaches a necessity for all types of organizations to ensure their protection. To implement an appropriate computer security policy, it is necessary to efficiently exploit the data that has become a valuable asset for these security systems, provided it is well used, controlled and monitored.In this paper, we focus on developing a decentralized solution based on Blockchain technology and IPFS (InterPlanetary File System) that can maintain and ensure the integrity of log files and sensitive information. The obtained results are promising, we obtained a distributed ledger of all log file transactions in a chronological sequence, which was shared among all Ethereum participants, allowing us to verify the log files' integrity, validity, and auditability throughout their life cycle.


The paper presents the new stability analysis for the collocation Trefftz method (CTM) for biharmonic equations, based on the new effective condition number Cond_eff. The Trefftz method is a special spectral method with the particular solutions as admissible functions, and it has been widely used in engineering. Three crack models in Li et al. (Eng. Anal. Boundary Elements 2004; 28:79–96; Trefftz and Collocation Methods. WIT Publishers: Southampton, Boston, 2008) are considered, and the bounds of Cond_eff and the traditional condition number Cond are derived, to give the polynomial and the exponential growth rates, respectively. The stability analysis explains well the numerical experiments. Hence, the new Cond_eff is more advantageous than Cond. Besides since the bounds of Cond_eff and Cond involve the estimation of the minimal singular value σmin of the discrete matrix F, and since the estimation of σmin is challenging and difficult, the proof for lower bounds of σmin in this paper is important and intriguing.

The big data technology has been widely used in power consumption behavior analysis and power user portrait. In this paper, the electricity data is constructed as two-dimensional time-series. Based on the designed data structure, a special kind of Artificial Neural Networks (ANNs) named as text convolutional neural networks (TCNN) is proposed for electricity theft detection. Moreover, considering the imbalance of electricity theft data in realistic datasets, a data augmentation method is proposed. Numerical results obtained on realistic datasets validate the proposed model.


The hydatic cyst cyts is a rare infectious parasitic pathology during pregnancy, which may affect all organs. The patient was a thirty six years old woman who underwent surgery for a hydatic cyst of the liver 14 years age. She had elective cesarean delivery due to maternal request. During the bleeding control, we palpated semi-cystic white mass with smooth border within omentum. Cystectomy was performed. Histopathologic examination was consistent with hydatic cyst. The recurrence rate and/or rapid progression of the disease increase with decreased celluler immunity during pregnancy. Hydatic disease is rarely observed during pregnancy therefore there is not any consensus regarding the recurrence rate and treatment modalities. Surgical removal of the cyst is the recommended and preferable management option in cases whom disease is diagnosed in perinatal period.


This work presents an investigation into the potential next generation of infrared detectors for radiation thermometry. Motivations for this work include increased detector sensitivity, development of minimally cooled mid-wave infrared (MWIR) arrays and longer wavelength multi-colour ratio radiation thermometers.

The high sensitivity of the Si avalanche photodiode (APD) is highly attractive for radiation thermometry. A Si APD is shown to offer increased sensitivity by measuring a lower temperature than a Si photodiode in order to satisfy specific threshold voltages. The Si APD is also shown to offer improvement in the signal-to-noise ratio (SNR) and temperature error. By combining the Si APD with a phase sensitive detection (PSD) method, further improvement is achieved.

The MWIR InAs/GaSb type-II superlattice (T2SL) offers the potential development of minimally cooled MWIR arrays for radiation thermometry, as well as longer wavelength multi-colour detectors for ratio radiation thermometry. An uncooled T2SL detector on a GaSb substrate is demonstrated for measurement of a target temperature of 25 oC with SNR > 1. Cooling improves the detector's performance, allowing operation at the thermo-electric cooler compatible temperature of 200 K. Further characterisation of a T2SL detector on a GaAs substrate demonstrates similar temperature dependence, suggesting challenges to the material growth for improved detector performance. Other potential challenges with T2SL development are identified and discussed.

The quantum dot infrared photodetector (QDIP) also offers the potential for longer wavelength multi-colour detection. Combination with an infrared algorithmic spectrometer (IRAS) offers flexibility for development of a versatile ratio radiation thermometer. The QDIP-IRAS combination is demonstrated to successfully reproduce arbitrary filter shapes from blackbody photocurrent measurements. Ratios computed using the IRAS correspond well with ratios computed from the arbitrary target filters.

An ultrasonic inspection system was proposed to observe a subsurface crack growth behavior continually in two-roller rolling fatigue test. A 50 MHz delay line contact probe was used in the system to detect clearly small cracks near the contact surface and to conduct the ultrasonic inspection while the test rollers were kept attached to the rolling fatigue testing machine. The ultrasonic wave pattern was analyzed by digital image processing to predict the position and shape of cracks . The proposed system was adequate to the inspection of a crack which had about 1 .5 mm circumferential extent parallel to the contact surface in the subsurface region and inadequate to the continual observation of cracks which originated at the contact surface. This result suggests that cracks originating at the contact surface hardly have a large enough extent to reflect the ultrasonic wave in the crack growth process but grow to failure very rapidly only in the final stage of the process .
