Developing concept on sponge city arrangement for flood hazard mitigation: A case study of Wuhan, China

As a frequently flooded city, Wuhan is one of the key cities that need to improve the abilities against flooding hazards. The recent rainstorms happened in Wuhan led to floods and threatened people’s lives as well as made huge economic losses so that it is urgent to develop an overall Sponge City System in Wuhan. This paper investigates the reasons that Wuhan frequently suffered from severe flooding hazards, including (1) flat topography, (2) heavy precipitation, (3) reduction of lake area, (4) decreased capacity of drainage system. By consideration of these conditions in Wuhan, specific methods based on Sponge City are recommended. According to overall consideration of waterlogging risk, flooding impacts and Sponge City effects, key regions that need to be given priority to develop Sponge City are proposed. Then, this paper proposes following Sponge City arrangement: (1) recovery of water ecosystem and water quality status in Wuhan is recommended. (2) Based on the existing gardens in urban area, adjustments of bio-retention or rain gardens including increasing the proportion of rain gardens in residential regions and along lakes are proposed. (3) GIS is used to analyze the topography, build rain flood model based on DEM and monitor the waterlogging in order to reduce flooding hazards and improve the ecological environment in Wuhan. By analysis and constructions of Sponge City in Wuhan, the harmful effects of flooding will be reduced and the ecological environment will be improved.
Radioactivity Measurements and Radiation Dose Assessments in Ground Water of Al-Baha Region, Saudi Arabia

Twenty samples of ground water were collected from different wells in Al-Baha region which is located at south-east of Saudi Arabia. Gamma spectrometer based on HPGe crystal was applied to determine activity concentrations in Bq·L-1 of the natural radio nuclides: Radium-226 and Thorium-232 series also Potassium-40. The measured results indicate that the average concentrations of 226Ra, 232Th and 40K in the studied samples were 0.85, 0.43, and 2.84 Bq·L-1, respectively. The average annual estimated effective dose was found to be 0.058 mSv/y which is lower than the annual limit of the dose allowed by WHO Thus, it has no harmful effects on health.
Non-adjuvant Single Low Dose Bevacizumab Intravitreal Injection Causes Resolution of Choroidal Metastases from Breast Carcinoma

INTRODUCTION Choroidal metastasis occurs in 7–11% of patients with breast carcinomas (1). Treatment includes external beam radiation therapy, tamoxifen, aromatase inhibitors (letrozole) and chemotherapy, including systemic bevacizumab (1–3). Bevacizumab, a monoclonal antibody, is anti-angiogenetic, thereby limiting tumour vascularization and growth. It has been approved for systemic use in colon carcinomas (4). Its “off label” use in ophthalmology has evolved from the treatment of age-related macular degeneration (ARMD) to proliferative diabetic retinopathy (PDR) and macula oedema (5–8). Bevacizumab is also an anti-vascular endothelial growth factor (VEGF) agent which reduces permeability and allows resorption of subretinal fluid.
Prevalence of Intestinal Parasitic Infections and Transmission Risk Factors in Primary School Children in Mbeere North Sub-County, Embu County, Kenya

Intestinal parasitic infections (IPI) such as soil transmitted helminths (STH) and protozoa can cause diverse negative effects on human health. The prevalence of IPI in primary school children in Mbeere North sub-county in Embu County is not documented, though there are many cases reported in health centers in the area. The aim of this study was to establish the current prevalence of IPIs in primary school children in Mbeere North sub-county and the factors that perpetuate Original Research Article Kamonge et al.; IJPR, 4(3): 1-7, 2020; Article no.IJPR. 57916 2 transmission which is necessary for implementation of suitable control programs in the study area. The study was done among primary school children from nine public schools. Three schools per administrative ward were randomly selected to represent each of the three administrative wards. A total of 414 pupils whose parents/guardians gave informed consent participated in the study, 46 pupils per school. Each participant provided a thumb size of early morning stool. The stool samples were processed by Formol-ether concentration technique and direct wet preparation methods for microscopic identification of intestinal parasites. A structured questionnaire was used to collect data on age, sex, sanitation and hygiene practices. The overall point prevalence of intestinal parasitic infections amongst the pupils was 43%. Chi-square (χ2) test was done to determine the relationship between prevalence and the pupils’ age and sex. There was no significant association between prevalence and sex (χ2 = 0.184, P = 0.668, df = 1) but a significant association was found between prevalence and age where children 11 years and below were more pre-disposed than those above 11 years old (χ2 =4.770, P=0.043, df =1). Similarly, a significant association was found between water source and prevalence of IPI; the parasites infection prevalence decreased when tap water was used and increased when open surface water was used (F = 6.15, P = 0.006). From this study, it is clear that IPIs particularly E. histolytica are a problem in primary school children in Mbeere North Sub-County. There is an urgent need for provision of safe domestic water in the county. Additionally, community education on sanitation and IPI transmission risk factors is urgently required. The information generated in this study is beneficial to the public health service in designing control strategies for areas of high transmission.
BoVSG: bag of visual SubGraphs for remote sensing scene classification

ABSTRACT Remote sensing scene classification is gaining much more interest in the recent few years for many strategic fields such as security, land cover and land use monitoring. Several methods have been proposed in the literature and they can be divided into three main classes based on the features used: handcrafted features, features obtained by unsupervised learning and those obtained from deep learning. Handcrafted features are generally time consuming and suboptimal. Unsupervised learning based features which have been proposed later gave better results but their performances are still limited because they mainly rely on shallow networks and are not able to extract powerful features. Deep learning based features are recently investigated and gave interesting results. But, they cannot be usually used because of the scarcity of labelled remote sensing images and are also computationally expensive. Most importantly, whatever kind of feature is used, the neighbourhood information of them is ignored. In this paper, we propose a novel remote sensing scene representation and classification approach called Bag of Visual SubGraphs (BoVSG). First, each image is segmented into superpixels in order to summarize the image content while retaining relevant information. Then, the superpixels from all images are clustered according to their colour and texture features and a random label is assigned to each cluster that probably corresponds to some material or land cover type. Thus superpixels belonging to the same cluster have the same label. Afterwards, each image is modelled with a graph where nodes correspond to labelled superpixels and edges model spatial neighbourhoods. Finally, each image is represented by a histogram of the most frequent subgraphs corresponding to land cover adjacency patterns. This way, local spatial relations between the nodes are also taken into account. Resultant feature vectors are classified using standard classification algorithms. The proposed approach is tested on three popular datasets and its performance outperforms state-of-the-art methods, including deep learning methods. Besides its accuracy, the proposed approach is computationally much less expensive than deep learning methods.
Effects of Model Resolution, Physics, and Coupling on Southern Hemisphere Storm Tracks in CESM1.3

Two high‐resolution versions of a Coupled Earth System Model (CESM1.3: 0.25° atmosphere, 1° ocean; CESM1.1: 0.25° atmosphere, 0.1° ocean) are compared to the standard resolution CESM1.1 and CESM1.3 (1° atmosphere, 1° ocean). The CESM1.3 versions are documented, and the consequences of model resolution, air‐sea coupling, and physics in the atmospheric models are studied with regard to storm tracks in the Southern Hemisphere as represented by 850‐hPa eddy kinetic energy. Increasing the resolution from 1° to 0.25° in the atmosphere (same physics) coupled to the 1° ocean intensifies the strength of the storm tracks closer to observations. The 0.25° atmosphere with the older CESM1.1 physics coupled to the 0.1° ocean has fewer low clouds, warmer Southern Ocean sea surface temperatures, a weaker meridional temperature gradient, and a degraded storm track simulation compared to the 0.25° atmosphere with CESM1.3 physics coupled to the 1° ocean. Therefore, deficient physics in the atmospheric model can negate the gains attained by higher resolution in atmosphere and ocean.
Effect of solute concentration on the spectral induced polarization response of calcite precipitation

Induced calcite precipitation is used in geotechnics to modify the mechanical and hydrological properties of the underground. Laboratory experiments have shown that spectral induced polarization (SIP) measurements can detect calcite precipitation. However, the results of previous studies investigating the SIP response of calcite precipitation were not fully consistent. This study aims to investigate how the SIP response of calcite depends on solute concentration to explain the differences in SIP response observed in previous studies. A four-phase experiment with SIP measurements on a column filled with sand was performed. In phase I, calcite precipitation was generated for a period of 12 d by co-injecting Na2CO3 and CaCl2 solutions through two different ports. This resulted in a well-defined calcite precipitation front, which was associated with an increase in the imaginary part of the conductivity ($\sigma ^{\prime\prime}$). In phase II, diluted solutions were injected into the column. This resulted in a clear decrease in $\sigma ^{\prime\prime}$. In phase III, the injection of the two solutions was stopped while calcite precipitation continued and solute concentrations in the mixing zone decreased. Again, this decreased $\sigma ^{\prime\prime}$. Finally, the injection rate of the Na2CO3 solution was reduced relative to that of the CaCl2 solution in phase IV. This resulted in a shift of the mixing zone away from the calcite precipitation front established in phase I and an associated decrease of $\sigma ^{\prime\prime}$. These results imply that the SIP response of calcite is highly sensitive to the solute concentration near the precipitates, which may explain previously reported conflicting results.
Incorporation of bevacizumab in the primary treatment of ovarian cancer.

BACKGROUND Vascular endothelial growth factor is a key promoter of angiogenesis and disease progression in epithelial ovarian cancer. Bevacizumab, a humanized anti-vascular endothelial growth factor monoclonal antibody, has shown single-agent activity in women with recurrent tumors. Thus, we aimed to evaluate the addition of bevacizumab to standard front-line therapy. METHODS In our double-blind, placebo-controlled, phase 3 trial, we randomly assigned eligible patients with newly diagnosed stage III (incompletely resectable) or stage IV epithelial ovarian cancer who had undergone debulking surgery to receive one of three treatments. All three included chemotherapy consisting of intravenous paclitaxel at a dose of 175 mg per square meter of body-surface area, plus carboplatin at an area under the curve of 6, for cycles 1 through 6, plus a study treatment for cycles 2 through 22, each cycle of 3 weeks' duration. The control treatment was chemotherapy with placebo added in cycles 2 through 22; bevacizumab-initiation treatment was chemotherapy with bevacizumab (15 mg per kilogram of body weight) added in cycles 2 through 6 and placebo added in cycles 7 through 22. Bevacizumab-throughout treatment was chemotherapy with bevacizumab added in cycles 2 through 22. The primary end point was progression-free survival. RESULTS Overall, 1873 women were enrolled. The median progression-free survival was 10.3 months in the control group, 11.2 in the bevacizumab-initiation group, and 14.1 in the bevacizumab-throughout group. Relative to control treatment, the hazard ratio for progression or death was 0.908 (95% confidence interval [CI], 0.795 to 1.040; P=0.16) with bevacizumab initiation and 0.717 (95% CI, 0.625 to 0.824; P<0.001) with bevacizumab throughout. At the time of analysis, 76.3% of patients were alive, with no significant differences in overall survival among the three groups. The rate of hypertension requiring medical therapy was higher in the bevacizumab-initiation group (16.5%) and the bevacizumab-throughout group (22.9%) than in the control group (7.2%). Gastrointestinal-wall disruption requiring medical intervention occurred in 1.2%, 2.8%, and 2.6% of patients in the control group, the bevacizumab-initiation group, and the bevacizumab-throughout group, respectively. CONCLUSIONS The use of bevacizumab during and up to 10 months after carboplatin and paclitaxel chemotherapy prolongs the median progression-free survival by about 4 months in patients with advanced epithelial ovarian cancer.

Probiotics for humans: hoax, hype, hope, or help

ABSTRACT Probiotics for preventing illness or improving health have become increasingly popular with consumers, researchers, and producers, both dairy companies and alternative medicine providers. They are widely available in foods such as yoghurt and as freeze dried capsules. They are used both for their general health effects on the gut including reducing travellers and antibiotic related diarrhoea. Their most important and best researched use is in the treatment of necrotising enterocolitis in premature babies where they reduce incidence, severity and mortality. The ultimate ‘probiotic’ mixture might be healthy human faeces which have been used for transplantation in patients with antibiotic resistant Clostridioides difficile infections with some success. Studies of allergy prevention using probiotics have shown mixed results. In New Zealand however, a specific strain of Lactobacillus rhamnosus (HN001) given from birth for two years has been shown to reduce the prevalence of allergic disease in infants throughout childhood. Further studies have shown a reduction in gestational diabetes amongst mothers who consume the probiotic during pregnancy. An important feature of the clinical use of probiotics is that different strains within the same species may have very different effects.
Does the Trunk Stability Push-Up Provide an Effective Measure of Upper-Body Function Specific to Male Team Sport Athletes?

Does the Trunk Stability Push-Up Provide an Effective Measure of Upper-Body Function Specific to Male Team Sport Athletes? Study background: The trunk stability push-up (TSPU) is a closed-chain test that can measure upper-body functional strength, but may not relate to sport-specific performance. The bilateral medicine ball chest pass (MBCP) is a more sport-specific openchain assessment. This research investigated whether the TSPU related to bilateral MBCP to determine whether it was a valid test of team sport upper-body function. The bilateral MBCP is a more effective test of upperbody function than the TSPU, and can discriminate between athletes with different upper-body function. This assessment related to the unilateral MBCP and TSPU, indicating its applicability for team sports.

Design of High-Selectivity Asymmetric Three-Way Equal Wideband Filtering Power Divider

An asymmetric three-way equal wideband filtering power divider with high selectivity is presented in this paper. The proposed three-way filtering power divider is an asymmetric structure which is composed of two different $\lambda $ /4 transformers, a pair of short-ended parallel coupled lines, an open-ended parallel coupled line, and a three-line parallel coupled line. Based on 2:1 unequal Wilkinson power divider, an equal three-way power divider is obtained with energy subdivided by three-line parallel coupled line. Subsequently, a Wilkinson power divider with the wideband filtering response is realized by adding a pair of short-ended parallel coupled lines that can provide multiple transmission zeros and poles. Presented with an equivalent circuit, the design procedure for asymmetric three-way equal filtering power divider is developed. Moreover, the reasons for and associated measures of large magnitude imbalance are also analytically developed. The measured results show that the proposed filtering power divider has more than 57.3% 1-dB fractional bandwidth, less than 0.4 dB insertion losses, better than 19.5 dB return loss, and more than 14.9 dB isolation from direct current to 3.3 GHz.

The study determined the nutritional challenges of persons with disability in special needs centers in mainland, Lagos State. Three research questions guided the study. Survey research design was adopted. The population of the study was 57. No sampling was done since the population was a manageable size. Validated questionnaire was used for data collection. Data collected were analyzed using mean and standard deviation. Findings showed that the types of disabilities among children in special need centers in Lagos State included among others: physical disability, learning disability, cerebral palsy, Down syndrome, attention deficit disorder/attention deficit hyperactivity disorder (ADHD), autism and speech and language disorder. Findings also revealed that the nutritional needs of children with disability included feeding on different foods, drinking water regularly, taking fruits daily, and ensuring that their nutrient requirements are met daily. Findings indicated that the nutritional challenges of children with disability included among others: excessive salivation, frequent constipation, inability to feed oneself, depending on care givers for feeding, food dropping from the mouth while being fed and difficulty in chewing and swallowing foods. Conclusion was made. Among recommendations made was that children with disabilities should be provided with variety of foods daily to meet their nutritional needs and parents/caregivers should devote more feeding time to the disabled child.
FUTURE CLIMATE UNCERTAINTY AND SPATIAL VARIABILITY OVER TAMILNADU STATE, INDIA

The present study analyses future climate uncertainty for the 21st century over Tamilnadu state for six weather parameters: solar radiation, maximum temperature, minimum temperature, relative humidity, wind speed and rainfall. The climate projection data was dynamically downscaled using high resolution regional climate models, PRECIS and RegCM4 at 0.22°x0.22° resolution. PRECIS RCM was driven by HadCM3Q ensembles (HQ0, HQ1, HQ3, HQ16) lateral boundary conditions (LBCs) and RegCM4 driven by ECHAM5 LBCs for 130 years (1971-2100). The deviations in weather variables between the end century (2071-2100) and the base years (1971-2000) were calculated for all grids of Tamilnadu for ascertaining the uncertainty. These deviations indicated that all model members projected no appreciable difference in relative humidity, wind speed and solar radiation. The temperature (maximum and minimum) however showed a definite increasing trend with 1.7 to 3.7°C and 1.9 to 4.3°C, respectively. The model members for rainfall exhibited a high uncertainty as they projected high negative and positive deviations (-325 to 784 mm). The spatial representation of maximum and minimum temperature indicated a definite rhythm of increment from coastal area to inland. However, variability in projected rainfall was noticed.
Position control of a series elastic actuator based on global sliding mode controller design

A series elastic actuator ( SEA ) is a powerful device in the area of human-machine integration, but it still suffers from difficult position control issues. Therefore, in this paper, an efficient approach is proposed to solve this problem. The approach design is divided into two steps: feedback linearization ( FL ) and global sliding mode ( GSM ) controller design. The bounded analysis is presented and global asymptotic convergence is analytically proven. Simulation and experiment results illustrate the effectiveness of the proposed scheme.
Word Sense Representation based-method for Arabic Text Categorization

Word embedding and document embedding representations have proved good performance in several natural language tasks such as information retrieval, text categorization, etc. Since, these representations capture both the synthetic and semantic information contained in the text. However, the ambiguity of Arabic language is a ubiquitous problem that can be handled by using sense embedding approaches. Learning a distinct representation for each sense of an ambiguous word could lead to train a more powerful and fine-grained models of vector-space representations. In this paper, we propose a method that combined document embedding representation and sense disambiguation to enhance Arabic text representation. Firstly, we benefit from sense embedding. Secondly, we enrich the document embedding model by learning representations for words and their senses and increasing the number of the document to train the model. The proposed method will be explored in the context of Arabic text categorization. Our system is composed of four stages which are: (1) preprocessing, (2) word sense disambiguation, (3) document embedding, (4) document categorization. We have conducted several experiments on OSAC corpus, the obtained results show that our method outperforms the state of art methods.
