Nitrogen removal from ammonium-contaminated groundwater using dropping nitrification–cotton-based denitrification reactor
Authors: Maharjan A. K. , Mori K. , Nishida K. , Toyama T. 
Published: August 2021

Abstract
A novel dropping nitrification–cotton-based denitrification reactor was developed for total nitrogen (N) removal from ammonium (NH4+)-contaminated groundwater. The nitrogen removal ability of the reactor was evaluated for 91 days. A 1 m-long dropping nitrification unit was fed with synthetic groundwater containing 30 mg-NH4+-N/L at a flow rate of 2.16 L/d. The outlet of the dropping nitrification unit was connected to the cotton-based denitrification unit. The NH4+ present in the groundwater was completely oxidized (&gt;90% nitrification efficiency) by nitrifying bacteria to nitrite (NO2–) and nitrate (NO3–) in the dropping nitrification unit. Subsequently, the generated NO2– and NO3– were denitrified (96%–98% denitrification efficiency) by denitrifying bacteria in the cotton-based denitrification unit under anoxic conditions. Organic carbons released from the cotton presumably acted as electron donors for heterotrophic denitrification. Nitrifying and denitrifying bacteria were colonized in higher abundance in the dropping nitrification and cotton-based denitrification units, respectively. The total N removal rate and efficiency of the dropping nitrification–cotton-based denitrification reactor for 91 days were 58.1–66.9 mg-N/d and 96%–98%, respectively. Therefore, the dropping nitrification–cotton-based denitrification reactor will be an efficient, sustainable, and promising option for total N removal from NH4+-contaminated groundwater.

Abstract
Gravel mulching is an ancient mulching system with a history of more than 300 years in China. To explore the changes of soil-water content (SWC) and heat transport in watermelon gravel-mulched fields under drip irrigation, we simulated three irrigation quotas (W1, 180 m3/hm2; W2, 270 m3/hm2; and W3, 360 m3/hm2) and three irrigation frequencies (F1, three times; F2, six times; and F3, nine times) based on HYDRUS-2D. The results indicated that peak SWC increased with irrigation quota. The range of fluctuation of SWC decreased as irrigation frequency increased. The temperature of the 0–40 cm soil layer varied with air temperature, but the range of fluctuation decreased with depth. Irrigation affected the distribution of soil water, increased soil heat capacity, and reduced the impact of air temperature on soil temperature, thus delaying the impact of air temperature on soil temperature. High-frequency drip irrigation could therefore effectively improve SWC, reduce water stress during the period of watermelon growth, and effectively delay the effect of air temperature on soil temperature, providing a theoretical basis for developing reasonable irrigation strategies and regulating soil water and heat in gravel-mulched fields.
Spatial distribution characteristics and health risk assessment of heavy metals in surface sediment of the Hai River and its tributaries in Tianjin, China

Published: August 2021

Abstract
To assess the spatial distribution characteristics and health risk of heavy metals (Cu, Zn, Ni, Cd, Pb, and Cr) in surface sediment of the Hai River and its tributaries in Tianjin, China, 32 surface sediment samples were collected. All the heavy metals mainly occurred in residue, except Cd. Cd primarily existed in the exchangeable fraction and posed a high risk to the aquatic environment. The mean values of pollution index followed a decreasing trend of Cu &gt; Cd &gt; Ni &gt; Pb &gt; Cr &gt; Zn. The results of health risk assessment showed that the heavy metals were not a threat to local residents and Cr and Pb were the main contributors to the health risk. The carcinogenic risk posed by Cr was two orders of magnitude higher than that posed by Cd. A self-organizing map divided the 32 sites into three clusters and more attention should be paid to cluster 3. The results will be conducive to understanding the heavy metal pollution patterns and implementing effective and accurate management programs.

Authors: Mannée Denise , de Jongh Frans , van Helvoort Hanneke 
Published: August 2021

Background
The Hexoskin is a smart shirt that can take continuous and objective measurements and could be part of a potential telemonitoring system.

Objective
The aim of this study was to determine the accuracy of the calibrated Hexoskin in measuring tidal volumes (TVs) in comparison to spirometry during various tasks.

Methods
In a cross-sectional study, the TV of 15 healthy subjects was measured while performing seven tasks using spirometry and the Hexoskin. These tasks were performed during two sessions; between sessions, all equipment was removed. A one-time spirometer-based calibration per task was determined in session 1 and applied to the corresponding task in both sessions. Bland-Altman analysis was used to determine the agreement between TV that was measured with the Hexoskin and that measured with spirometry. A priori, we determined that the bias had to be less than ±5%, with limits of agreement (LOA) of less than ±15%. Lung volumes were measured and had to have LOA of less than ±0.150 L.

Results
In the first session, all tasks had a median bias within the criteria (±0.6%). In the second session, biases were ±8.9%; only two tasks met the criteria. In both sessions, LOA were within the criteria in six out of seven tasks (±14.7%). LOA of lung volumes were greater than 0.150 L.

Conclusions
The Hexoskin was able to correctly measure TV in healthy subjects during various tasks. However, after reapplication of the equipment, calibration factors were not able to be reused to obtain results within the determined boundaries.

Authors: Ritchie Natalie D. , Sauder Katherine A. , Kaufmann Peter G. , Perreault Leigh 
Published: August 2021

OBJECTIVE
Difficulty achieving preset goals (e.g., ≥5% weight loss, ≥150 min of weekly physical activity) in the yearlong National Diabetes Prevention Program (NDPP) can prompt dropout and diminish benefits. We piloted a more patient-centered NDPP adaptation (NDPP-Flex) that promotes a variety of attainable and individually tailored goals to reduce diabetes risks, along with flexibility to adjust goals each week as needed.

RESEARCH DESIGN AND METHODS
Retention, physical activity, weight, and glycated hemoglobin (HbA1c) were evaluated among diverse participants with diabetes risks who received our pilot of NDPP-Flex beginning in January and July 2018 (n = 95), with a planned comparison with standard NDPP delivery in preceding cohorts that launched between September 2016 and October 2017 (n = 245). Both the standard NDPP and NDPP-Flex interventions were 1 year in duration and implemented in phases (i.e., nonrandomized).

RESULTS
Average adjusted retention (e.g., 158.90 ± 15.20 vs. 166.71 ± 9.38 days; P = 0.674), physical activity (157.97 ± 11.91 vs. 175.64 ± 7.54 weekly min; P = 0.231), and weight loss (1.46 ± 0.38% vs. 1.90 ± 0.24%; P = 0.396) were similar between NDPP-Flex versus standard NDPP. However, NDPP-Flex participants had greater HbA1c reduction on average (0.22 ± 0.05% vs. 0.06 ± 0.03%; P = 0.018) and were more likely to have normoglycemia at follow-up (odds ratio 4.62; P = 0.013 [95% CI 1.38–15.50]) than participants in the standard NDPP.

CONCLUSIONS
An adapted, more patient-centered NDPP that focuses on flexible, self-selected goals may be a promising strategy to improve glycemia even in the absence of substantial weight loss.

Islamic education on convergence theory is based on the concept of Hablummiallah (relationship with Allah), in the sense that it is Allah who gives the initial potential so that in Islamic education that personality must be formed and developed for ma'rifatullah (knowing Allah) and fearing Allah even apart from believing in that internal (innate) and external (environmental) factors are very influential in education, and form a quality Muslim personality. So the most important thing is to acknowledge guidance from Allah as a determinant of success in education and Hablumminannas (relations with humans) as a form of change in human personality in social or environmental life, with the formation of human beings who are sure to make state apparatus aware of the law and able to become pioneers upholding the law in Indonesia.
Abstrak
Pendidikan Islam terhadap teori konvergansi, berpatokan pada konsep Hablummiallah (hubungan dengan Allah), dalam artian bahwa Allah lah yang memberikan potensi awal sehingga dalam pendidikan Islam kepribadian itu harus dibentuk dan dikembangkan untuk ma’rifatullah (mengenal Allah) dan bertakwa kepada Allah bahkan Selain meyakini bahwa faktor internal (bawaan) dan eksternal (lingkungan) sangat berpengaruh dalam pendidikan, dan membentuk kepribadian muslim yang berkualitas. Maka yang terpenting adalah harus mengakui hidayah dari Allah sebagai penentu keberhasilan dalam pendidikan dan Hablumminannas (hubungan dengan manusia) sebagai wujud perubahan kepribadian manusia dalam kehidupan sosial atau lingkungan, dengan terbentuknya Manusia yang taan tentunya akan menjadikan insan aparatur negara yang sadar hukum serta mampu menjadi pelopor tegaknya hukum di Indonesia.

Published: August 2021

Stroke is one of the foremost common disorders among the elderly. Early detection of stroke from Magnetic Resonance Imaging (MRI) is typically based on the representation method of these images. Representing MRI slices in two dimensional structures (matrices) implies ignoring the dependencies between these slices. Additionally, to combine all features exist in these slices requires more computations and time. However, this results in inexact diagnosis. In this paper, we propose a new tensor-based approach for stroke detection from MRI. The proposed methodology has two phases. In first phase, each patient’s MRI are represented as a tensor. Tensor representations are powerful because they capture the dependencies in high-dimensional data, MRI of patient, which gives more reliable and accurate results. Also, tensor factorization is used as a method for feature extraction and reduction, which improves the performance and accuracy of classifiers. In second phase, these extracted features are used to train support vector machine (SVM) and XGBoost classifiers to classify MRI images into normal and abnormal. The proposed method is assessed with MRI dataset, and the conducted experiments illustrate the efficiency of this approach. It achieves classification accuracy of 98%.

Published: August 2021

According to current concepts, ruminal and metabolic acidosis occur due to feeding cattle mainly with preserved acidic feeds such as silage and haylage. However, errors in feeding are not the only etiological factor leading to acidosis. In some cases, metabolic acidosis in cattle can develop along with respiratory infection caused by viral and bacterial agents. The main pathological processes resulting from acute respiratory diseases of cattle are bronchitises, tracheites and pneumonias. When the respiratory tract is affected in cattle, hypoxia occurs, causing intoxication and, thus, leading to ruminal acidosis. As a result, vasoactive substances (bacterial endotoxins, histamine, lactate) enter the bloodstream, the vascular endothelium is damaged due to the simultaneous expansion of arterioles and compression of venules, blood fluid is perfused from the vessels into the surrounding tissues, the blood flow in the microcirculatory bed is disrupted. An important role in the disturbance of blood circulation in small blood vessels is played by circulating immune complexes representing the «antigen-antibody» complex. Low molecular weight circulating immune complexes settle in various organs and tissues of the body, lead to inflammation and damage the normal tissue structure. Most frequently, immune complexes affect the endothelium of blood vessels, renal glomeruli and joints. Distal limb vessels are primarily affected in cattle, leading to disturbance of skin trophism of the limbs and hooves, development of laminitis, while the hoof horn is weakly keratinized and cannot resist aggressive mechanical and chemical environmental factors. Damaged hooves are the gateway of infection for the agents of necrobacteriosis (Fusobacterium necrophorum), staphylococcosis (Staphylococcus spp.), streptococcosis (Streptococcus spp.) and other pathogens. In addition, favorable conditions evolve for the development of mixed infection due to reduction in the overall organism resistance, which is observed for both respiratory and distal limb infections.

Specific prevention is one of the most effective methods for the control of infectious diseases causing considerable economic damage to commercial pig farms, among which is porcine pleuropneumonia. In order to improve the effectiveness of preventive vaccination, various immunomodulators that differ in their origin and mechanism of action are used. The paper presents the results of the study of the effect of such products as biferon-S and prostimul containing species-specific recombinant interferons on the immune status of piglets during specific prevention of porcine pleuropneumonia. Tests were carried out in clinically healthy 30–35-day-old piglets immunized with Ingelvac® APPX vaccine (Boehringer Ingelheim Vetmedica GmbH, Germany). It was found that the use of biferon-S and prostimul together with the vaccine administration is accompanied by immune status improvement in the animals, which is manifested as an increase, in comparison with vaccinated animals that received no interferon-containing products (base case), in serum levels of γ-globulins – by 34.6 and 53.7% (in case of prostimul and β-globulins – by 10.1%), total immunoglobulins – by 32.8 and 37.8%, large circulating immune complexes – by 37.5 and 52.6%, a less significant increase in the levels of small complexes and, as a result, pathogenicity coefficient reduction by 5.4 and 12.4%, respectively. Tests for post-vaccination immunity levels in piglets showed a 3.8-fold increase in the levels of specific antibodies against the antigen of porcine pleuropneumonia agent, and in case of the vaccine administration in combination with biferon-S and prostimul – a 4.0-fold and 4.9-fold increase, respectively. The use of prostimul was accompanied by a more considerable improvement of immune status in the piglets, and this is attributable to the fact that vitamins А, Е and С, which have antioxidant properties and improve the effectiveness of interferons, natural resistance and specific immunity, are included in its composition in addition to recombinant type 1 cytokine.

The Veterinary Service of the Russian Federation takes measures to ensure regular control of livestock health status, to prevent infectious diseases and their introduction into the country; and if such diseases are diagnosed, it takes measures to prevent their spread and contain outbreaks as soon as possible. Success of the taken measures depends on the use of various diagnostic, preventive and therapeutic drugs. In order to produce such medicinal products, biofactories use production and reference strains with stable biological properties, which are stored in national collections of microorganisms. The only keeper of glanders strains is the Laboratory for Collection of Strains of Microorganisms in the FSBSI «FCTRBS-ARRVI», subordinated to the Ministry of Agriculture of the Russian Federation. The following steps were taken due to the official request from FKP Kursk Biofactory – BIOK Company for the transfer of Burkholderia mallei production strain 5584 from the collection of the institution: the strain was passaged in golden hamsters, its viability was determined and biological properties of the culture were studied. The strain was transferred in accordance with the established procedure and in compliance with the biosafety requirements. As the work progressed, Burkholderia mallei strain 5584 culture was isolated and freeze-dried. Before the transfer, biological properties of the freeze-dried Burkholderia mallei strain 5584 were studied for their compliance with the passport data. The obtained results showed that the Laboratory for Collection of Strains of Microorganisms in the FSBSI «FCTRBS-ARRVI» provides optimal conditions to preserve the strain viability and initial biological properties after 5 years of storage. Analysis of the data obtained during the transfer of Burkholderia mallei strain 5584 allowed us to assess the actions taken at all stages of the procedure. It was established that the transfer procedure for the requested glanders production strain complied with the biosafety requirements and regulatory framework regulating the process.
