A new landslide classification method based on electrical differences and relevant examples

A new landslide classification method based on electrical differences is proposed in this paper. The electrical parameters are obtained by the high-density electrical method, which is commonly used in landslide exploration. In this paper, landslides are divided into four categories based on the electrical difference between overburden and bedrock, and on this basis, the landslides are further divided into four categories according to the local electrical difference of landslides, totally eight kinds of landslides. The high-density resistivity method works well for exploration of both type I and type II slides. However, for type III and type IV, other geophysical methods should be supplemented. For type V-VIII landslides, they are simplified into type I-IV landslides in sections according to their electrical characteristics. As for complex landslides caused by multiple factors, more survey lines need to be laid systematically, combined with various methods, as well as information of drilling and trenching for comprehensive prospecting. The landslide classification method proposed in this paper provides some basis and reference for landslide exploration.
Performance and welfare of dairy cattle in an alternative compost bedded pack housing in a pasture-based system

The objective of this study was to assess the performance and welfare (lameness, hock lesions, mastitis) of loose-housed dairy cattle managed under grazing or semi-grazing system. Data of thirty-two cows before and after changing to semi-grazing system during the rainy season (week 1 to 4; grazing, week 6 to 9; semi-grazing) and before and after changing to semi-grazing (week 11 to 16; grazing, week 18 to 23, semi-grazing) during the dry season were examined. Cows were evaluated weekly for 24 weeks for somatic cell count (SCC), lameness, hock lesions, and hygiene. Milk yield was collected daily. Bacteria cultures were prepared to identify pathogens. Isolates were subjected to sensitivity tests. No difference was observed between grazing and semi-grazing, regarding milk yield, lameness, hock lesions, SCC, and sub-clinical mastitis prevalence. Mean SCC under grazing was >600,000 cells/ml, indicating infection with major pathogens (Streptococcus agalatiae, Streptococcus dysgalatiae). Klebsiella species increased with season and were less sensitive to common antibiotics. Contagious pathogens in milk were lower (14%) compared with environmental pathogens (82%). Because Klebsiella species were less sensitive to many antibiotics, keeping cows healthy is critical. Focus on reducing somatic cell count will be important in preventing mastitis infection in dairy cows. Key words: Grazing, semi-grazing system, performance, cattle welfare.

Insufficiency of Oral Communication Performance of Kurd EFL Undergraduate Learners at the Universities of Kurdistan: Reasons and Suggested Solutions

Insufficiency of oral communication performance is noticed among Kurdish EFL learners at the universities of Kurdistan region of Iraq. Thus, the current study investigates the reasons behind this issue and attempts to suggest solutions for it. The data has been gathered among 120 Kurdish EFL university students and 20 instructors at the universities of Charmo and Sulaimani. The results and discussion of the data gathered identify the main reasons behind the issue as students’ shyness, fear of losing face, reliance on L1 use, lack of self-confidence and de-motivation; that is in addition to the lecturers’ focusing mainly on grammar and writing skill and ignoring listening skill. In addition, the paper suggests solutions for the issue which are mainly overcoming students’ shyness, focusing on listening and speaking skills and avoiding L1 use in the class.
Martensitic Transformation and Metamagnetic Transition in Co-V-(Si, Al) Heusler Alloys

This study investigates the crystal structure, martensitic transformation behavior, magnetic properties, and magnetic-field-induced reverse martensitic transformation of Co64V15(Si21–xAlx) alloys. It was found that by increasing the Al composition, the microstructure changes from the martensite phase to the parent phase. The crystal structures of the martensite and parent phases were determined as D022 and L21, respectively. Thermoanalysis and thermomagnetization measurements were used to determine the martensitic transformation and Curie temperatures. Both the ferromagnetic state of the parent phase and that of the martensite phase were observed. With the increasing Al contents, the martensitic transformation temperatures decrease, whereas the Curie temperatures of both the martensite and parent phases increase. The spontaneous magnetization and its composition dependence were also determined. The magnetic-field-induced reverse martensitic transformation of a Co64V15Si7Al14 alloy under pulsed high magnetic fields was observed. Moreover, using the results of the DSC measurements and the pulsed high magnetization measurements, the temperature dependence of the transformation entropy change of the Co-V-Si-Al alloys was estimated.
Ionic liquid modified PEEK-MWCNTs nanocomposites with enhanced thermomechanical properties

Polyetheretherketone (PEEK) is a stable semi-crystalline thermoplastic polymer with excellent thermal and chemical properties and is used in many applications, especially as a biomaterial. However, poor mechanical properties: mismatching of elastic modulus to human bone retards the use of PEEK as a biomaterial for bone implant material. In the present study, ionic liquid (IL) modified multiwalled carbon nanotubes were used to prepare PEEK nanocomposites via internal mixer and compression molding processes. The morphologies, thermal and mechanical properties of the prepared nanocomposites were evaluated. Uniform and excellent distribution of MWCNTs into PEEK was achieved by optical microscopy. The thermogravimetric study showed that the decomposition temperature of the composites was boosted 7 % ± 0.9 as compared to those of PEEK composites prepared without IL. Moreover, the elastic modulus of the PEEK nanocomposites was improved by ionic liquid modified MWCNTs into the PEEK. Thus, the prepared PEEK nanocomposites have the potential to be used for fabricating bone implants.
Nanoscale lanthanum oxide catalysts for self-condensation of acetone: preparation via self-assembly on anodic aluminum oxide, structure, and properties

A novel structured La2O3/AAO solid base catalyst was prepared by supporting lanthanum oxide (La2O3) on the surface of anodic aluminum oxide (AAO) under hydrothermal conditions. Catalytic activity of the catalyst was tested using self-condensation of acetone to diacetone alcohol as a probe reaction. The conversion of acetone reached 4.14% with the diacetone alcohol selectivity of 98%. The catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), thermogravimetric analysis (TGA), N2 adsorption-desorption (BET), and temperature programmed desorption (CO2-TPD). XRD patterns and SEM images indicated that La2O3 nanoscale particles with high crystallinity were uniformly distributed over the AAO surface. The results of CO2-TPD showed that the calcination temperature led to the formation of medium-strength basic sites, strong basic sites, and to an increase of the basic strength. The strong basic sites and large basic strength are an important factor that influences the catalytic activity in the self-condensation of acetone to diacetone alcohol.
Comparison of Different Obesity Indices associated with Type 2 Diabetes Mellitus Among Different Sex and Age Groups in China

Background: Obesity is associated with type 2 diabetes mellitus (T2DM), but the obesity index most closely related to type 2 diabetes is still controversial. Therefore, the aim of this study was to compare the associations of five anthropometric indices (body mass index (BMI), body adiposity index (BAI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR)) with Type 2 diabetes mellitus (T2DM) among Chinese adults divided into four groups according to sex and age.Methods: A total of 4,007 adult participants (1,669 males and 2,338 females) were included. Odds ratios (OR) and 95% confidence intervals were used with binary logistic regression models to estimate the risk of T2DM for each obesity index. Furthermore, we compared the area under the ROC curve (AUC) of each obesity index for the criterion of hypertension under the influence of risk factors. Results: For the males, WC had the highest value of OR (3.211 and 1.452) and AUC (0.783 and 0.614) in both age groups. However, WHtR (OR=2.366, AUC=0.771) and BMI (OR=1.596, AUC=0.647) tended to be the best criteria for T2DM among females in the 18-59 and ≥60 years age groups, respectively.Conclusions: This study suggests that there is a positive association of obesity-related anthropometric indices with T2DM in different sex and age groups. For males, WC appears to be the best anthropometric index for predicting T2DM. For 18-59 and ≥60 age women, the best obesity indices related with T2DM are WHtR and BMI, respectively.
A Non-Standard Finite Difference Scheme for Magneto-Hydro Dynamics Boundary Layer Flows of an Incompressible Fluid Past a Flat Plate

This paper deals with a non-standard implicit finite difference scheme that is defined on a quasi-uniform mesh for approximate solutions of the Magneto-Hydro Dynamics (MHD) boundary layer flow of an incompressible fluid past a flat plate for a wide range of the magnetic parameter. The proposed approach allows imposing the given boundary conditions at infinity exactly. We show how to improve the obtained numerical results via a mesh refinement and a Richardson extrapolation. The obtained numerical results are favourably compared with those available in the literature.
Recognition of earthquake-prone areas in the Altai-Sayan-Baikal region based on the morphostructural zoning

The goal of the study is to identify the possible locations of strong M6+ earthquakes in the Altai-Sayan-Baikal region. The first stage of the study is compiling the morphostructural map of the region by means of the morphostructural zoning method (MSZ). The map presents the hierarchical block structure of the region, the network of morphostructural lineaments bounding the blocks, and loci of the nodes forming around lineament intersections. Epicenters of M6+ earthquakes reported by earthquake catalogues nucleate at nodes. We apply the pattern recognition approach to identify among all nodes seismogenic nodes D capable of generating M6+ earthquakes. This is done based on the description of the nodes by a set of geological and geophysical characteristics measured uniformly for all nodes. The result of the pattern recognition is twofold: (i) the rule of recognition that allows to recognize D nodes among the whole set of nodes; (ii) the actual division of nodes according to this rule into separate two classes: seismogenic D nodes and N nodes where the target events are unlikely. In the region under consideration, the whole set of 97 nodes has been divided into 33 D nodes and 64 N nodes. The target earthquakes have not yet been recorded at 17 D nodes indentified in this work. These susceptible nodes are located on the high rank lineaments separating major morphostructures of the region. High seismic potential of some of such nodes is confirmed by paleoseismic features defined in the region by other researchers.
Mechanisms of power inscription into IT governance: Lessons from two national digital identity systems

Establishing IT governance arrangements is a deeply political process, where relationships of power play a crucial role. While the importance of power relationships is widely acknowledged in IS literature, specific mechanisms whereby the consequences of power relationships affect IT governance arrangements are still under‐researched. This study investigates the way power relationships are inscribed in the governance of digital identity systems in Denmark and the United Kingdom, where public and private actors are involved. Drawing on the theoretical lens of circuits of power, we contribute to research on the role of power in IT governance by identifying two distinct mechanisms of power inscription into IT governance: power cultivation and power limitation.
A comprehensive review on time‐delay compensation techniques for grid‐connected inverters

The control of grid-connected inverters is recently executed with digital microprocessors due to the advances in digital signal processing technology. However, the digital realisation has a drawback of the phase lag induced by the time-delay. This phase lag challenges the stability and robustness of the controller of the inverters. In view of the challenge, this paper presents a comprehensive review of time-delay compensation techniques employed in both model-free (MF), and model-based (MB) controls of an inverter in grid connection. MF techniques mainly use proportional-integral, and proportional resonance controllers with some techniques to reduce time-delay. Meanwhile, for MB, this paper discusses the commonly used control techniques, which are the Smith predictor, modiﬁed Smith predictor, deadbeat controller and model predictive controller. Several related techniques from the literature that have been adopted to mitigate the delays are tabulated comprehensively, and critical issues regarding the MF and MB techniques are also discussed. Finally, this paper presents a on which suggests a hybrid technique from the and to give a for

Structural modeling for usability attributes on technology acceptance model for smart parking mobile application

Smart parking is a mobile application that is created to overcome parking problems, although there are many smart parking applications developed in the world, only a few have a good interface design. One of the methods to assess the quality of the interface design is by measuring the usability of the application. Also, several studies have explored the relationship between usability and TAM (Technology Acceptance Model). However, is still lacking, especially about smart parking as an object. Due to that, this study focuses on determining usability attributes in smart parking applications and also modelling that usability attributes to TAM. This study using SEM (Structural Equation Model) method for modelling the relationship between Usability and TAM. The goal is the model could be used as a guide by application developers to see what factors must be considered when designing a smart parking mobile application, and for future research, it is expected that the developed model can be used as a guide when measuring the usability of a smart parking application. This research proposed ten hypotheses and findings two hypotheses have no significant effect that would be explained furthermore in the result and discussion section.
Induction of Artesunate Resistance in Plasmodium falciparum 3D7 Strain Using Intermittent Exposure Method and Comparing P.fk13 Sequence between Susceptible and Resistant Strains

Background: Resistance to artemisinin has threatened major achievements in malaria control, more investigations is needed about resistant strains and related genes. We aimed to induce resistance to artesunate in the Plasmodium falciparum 3D7 strain using intermittent exposure method and comparing P.fk13 gene sequence between susceptible and resistance strains. Methods: P. falciparum 3D7 strain was cultured according to Trager & Jensen method with some modifications. Serial concentrations between 10−2 mol/l, to 10−7mol/l were prepared, then P. falciparum 3D7 was exposed to each of the dilution to determine IC50 and lethal dose. Sensitivity reduction process was started from the concentration of 10−7mol/l and ended at 10−2mol/l. Exposed parasites were collected after at least 27 days after cultivation in each drug concentration. DNA extraction, PCR and sequencing process were performed to investigate any possible mutations in the P.fk13 gene sequence. Results: Effectiveness of 10−2mol/l concentration of artemisinin was found as a lethal dose. IC50 value was equal to 5×10−4 mol/l. The resistant strain was provided in the lab, sequenced and registered in the gene bank as P.f Art −2, (accession number MH796123. 1). Alignment of this registered sample showed no mutation in P.f kelch13 gene in comparison with standard strain submitted in the GenBank. Conclusion: Resistance to artesunate in malaria parasite may occur but with no mutation in the P.f kelch13 gene. Therefore, whole genome sequencing should be applied to determine mutations in resistant strains.
Quantitative assessment of the oxygen isotope composition of fish otoliths from Lake Mungo, Australia

Abstract The Willandra Lakes region is a series of once interconnected and now-dry lake basins in the arid zone of southeastern Australia. It is a UNESCO World Heritage Site of cultural, archaeological, and geological significance, preserving records of Aboriginal occupation and environmental change stretching back to at least 50 ka. Linking the archaeology with the commensurate palaeoenvironmental information is complicated by the millennial time spans represented by the past hydrological record preserved in the sediment vs. the subdecadal evidence of each archaeological site. Oxygen isotope records across annual growth rings of fish otoliths (ear stones) can elucidate flooding and drying regimes on subannual scales. Otoliths from hearth sites (fireplaces) link lake hydrology with people eating fish on the lakeshore. Oxygen isotopic trends in hearth otoliths from the last glacial maximum (LGM) were previously interpreted in terms of high evaporation under dry conditions. However, this ignored hydrology-driven changes in water δ18O. Here, a mass balance model is constructed to test the effect lake desiccation has on water δ18O and how this compares with the LGM otolith records. Based on this modelling, we suggest that Lake Mungo otolith signatures are better explained by evaporation acting on full lakes rather than by lake drying.
Improvement of cardiomyopathy after ketogenic diet in a patient with Leigh syndrome caused by MTND5 mutation

BackgroundMitochondrial diseases (MDs) are heterogeneous group of disorders caused by inborn defects in the mitochondrial respiratory chain (MRC) and malfunctions of cellular oxidative phosphorylation (OXPHOS). MDs are caused by mutations both in mitochondrial and nuclear DNA. Leigh syndrome (LS) is a neurodegenerative MD with specific clinical and neuroradiological features. There is a broad clinical spectrum of MDs, including organ-specific and multiorgan presentations with symptoms occurring at any age. High energy requiring organs are most frequently involved and cardiac involvement is common. At present there is no specific treatment for MD. Ketogenic diet (KD) has been proposed as a treatment option for patients with MD with seizures or myopathy. It is suggested that KD itself may trigger cardiological complications after long-term therapy, but according to an animal model study, KD could be considered as a therapeutic option for some mitochondrial cardiomyopathies.MethodHere we present a retrospective case report on a male infant diagnosed with LS (m.12706T > C in MTND5) with severe progressive hypertrophic cardiomyopathy, with significant cardiological improvement after KD implementation . ResultsThe ketogenic diet was introduced in a male infant with clinical, biochemical and radiological features of Leigh syndrome, confirmed by next-generation sequencing (NGS) (known pathogenic variant in mtDNA), suffering from severe progressive hypertrophic cardiomyopathy and heart failure with no significant improvement on cardiological treatment, mitochondrial cocktail therapy and mechanical ventilation. The follow-up after KD initiation have shown significant clinical improvement in cardiovascular efficiency and echocardiographic parameters with no adverse effect observed so far.ConclusionScreening for cardiomyopathy is a standard of care (SoC) in the management of patients with mitochondrial disease. Although there are reports suggesting the efficacy and safety of KD in patients with mitochondrial disease, more studies are needed to understand the pathophysiology of mitochondrial diseases and to determine which patients are likely to benefit from this therapy.
Immoral and irrational cyclists? Exploring the practice of cycling on the pavement

ABSTRACT Cycling on the pavement is commonly seen in urban environments despite often being prohibited. This study explores this practice by analysing cycling on pavements in the wider socio-technical context in which it occurs. Using data from two field studies and one questionnaire study, as well as applying a Social Practice Theory (SPT) based analytical approach, the study explores the frequency of cycling on the pavement. The results show that riding on the pavement is common among cyclists. Three main configurations of meaning, material and competence constitutes this practice which is summarised as follows: avoiding the space of the car, increasing smoothness of the ride and unclear infrastructure design. Cycling on the pavement can be regarded as a way of managing safety and risk, seeking more efficient and comfortable paths of travel, as well as the outcome of perceiving the infrastructure as ambiguous. Overall, the study argues that cycling on the pavement is a consequence of skewed power relations between different modes of transport, as well as policies, urban planning and infrastructure not harmonising with demands for safe and smooth travel by cyclists.
