Characteristics of Stormwater Quality in Singapore Catchments in 9 Different Types of Land Use

Stormwater quality is well known for its highly stochastic nature and not necessarily well explained by mechanistic urban build up and wash off models. Therefore, local empirical data (based on land use) are an essential compliment to statistical analyses of global data. This paper reports on a large-scale monitoring of the 12 key water quality parameters of suspended solids, nutrients, and heavy metals for stormwater runoff in urban discharges from nine urban land uses with varying sizes in Singapore. It was found that, in general, the average of the event mean concentrations for total nitrogen, total phosphorus, total organic carbon, total suspended solids (TSS), and phosphate in parkland land use were higher than the other eight studied land uses. Based on Pearson’s correlation analysis, significant correlation between pairs of water quality parameters was observed. Particularly, there was significant correlation between TSS and most of the other tested water quality parameters in all land uses. A pollutant data set from this study will assist in developing appropriate stormwater quality models, guide the establishment of stormwater treatment objectives and preliminary designs for Singapore catchments, as well as provide an essential complement to statistical analyses of global data for stormwater characteristics.
Comportamiento de descargadores de sobretensión ante tensiones inducidas por rayos sobre líneas de distribución ubicadas en zona montañosa

Este artículo analiza cómo la ubicación de descargadores de sobretensión, en líneas de distribución sobre zonas montañosas, afecta las tensiones inducidas que se presentan en estas líneas a causa de rayos. Se consideraron cuatro configuraciones de terreno no plano, que son representativas de la topografía colombiana. La inclusión del terreno, el canal de la descarga, la línea de distribución y el cálculo de las tensiones inducidas, se realizó por medio del método de diferencias finitas en el dominio del tiempo en coordenadas cartesianas en tres dimensiones. Se encontró que las tensiones inducidas en terrenos no planos están entre 2 a 5 veces las que se obtienen para líneas sobre terrenos planos. En el caso de los terrenos A, C y D simulados, las tensiones inducidas superaron los umbrales de operación normales de los descargadores de sobretensión, lo que supone que aquellos ubicados en líneas de distribución en zonas de montaña tienen esfuerzos adicionales a los que se presentan en terreno plano. Sin embargo, hay una configuración (la B), donde no se superan dichos umbrales.
Low-Power Communication for an Implanted Intracortical Visual Prosthesis

Assisting visually impaired people to see again using technology is quite challenging, especially for cases where most of the visual pathway is damaged. The only viable option is to stimulate the visual cortex directly. Sending the stimulation data to electrodes on the visual cortex is preferably done wirelessly to avoid infections and to ease mobility. The receiver on the implant poses a challenge in design, as the power supply is limited. In this paper, vital system requirements for this communication link are discussed. A low power system-level approach is presented which seeks to avoid power hungry components. This leads to the consideration of a bandpass sampled phase shift keying scheme via an inductive link. We propose a non-coherent digital demodulator, which relaxes the need for low phase noise oscillators which consume more power and, also avoids the use of phase locks loops. The overall communication system has a potential to deliver stimulation data to the implant side in the presence of simultaneous power transfer and reception of recorded data from the brain.
Does prey elemental stoichiometry influence copepod movement over ontogeny?

Many planktonic consumers alter their behavior depending on the concentration of food in the environment, but responses to changes in food quality, as characterized by its elemental stoichiometry, are less well understood. Because of different nutritional demands across life history stages, consumer's responses to prey quality may vary across ontogeny. We build on previous observations of consumer selectivity and responses to prey presence by examining responses of displacement and movement patterns to prey stoichiometry. We used high‐speed videography to quantify displacement and movement patterns of the marine copepod, Acartia tonsa, as they varied with elemental content of microalgal food offered during preconditioning and during imaging trials. Life stages were sensitive to different nutrient elements in prey, with movement in copepodites generally varying with nitrogen content, and in adults with both nitrogen and phosphorus content. Net displacement was lower when adults and copepodites were offered fully replete and nitrogen‐replete food, respectively. Displacement of adults was more sensitive to the quality of food offered during preconditioning, and displacement of copepodites was affected by food quality during both preconditioning and trials. Naupliar displacement and movement patterns were generally insensitive to food quality. Only adults significantly altered movement patterns associated with feeding in response to food quality; adult helical swimming significantly increased in the treatments in which stoichiometrically replete food was offered in both preconditioning and behavioral trials. Older stages of A. tonsa alter movement in response to food quality in ways that may allow the selective use of patches of high‐quality prey.
Antenna array design with rectangular ring slot for 5G technology

A patch antenna with rectangular-shaped ring slot that fed by a coaxial probe is proposed in this article as the single element for planar patch array antenna design to meet the requirement of multiple input multiple output (MIMO) in fifth generation (5G) technology. Initially, the single antenna element is designed at three different center frequencies of 0.85, 1.9 and 2.6 GHz to cover the mobile operating frequency of 0.8, 0.85, 0.9, 1.8, 2.1 and 2.6 GHz, which considering the proposed 5G spectrum below than 6 GHz. The rectangular-shaped ring slot is introduced to the patch antenna with the partial ground plane to widen the bandwidth performance. The designed single element is then arranged to design planar arrays of 2 x 2. Each of elements in the planar array is fed by a coaxial probe. The designs are utilizing a high-performance substrate, Rogers 6010LM.

Design, synthesis, antitubercular and antibacterial activities of pyrrolo[3,2-b]pyridine-3-carboxamide linked 2-methoxypyridine derivatives and in silico docking studies

Abstract A novel series pyrrolo[3,2-b]pyridine-3-carboxamide linked 2-methoxypyridine derivatives have been designed, synthesized and confirmed by FT-IR, 1H NMR, 13C NMR, 19F NMR, MS, and elemental analysis. The synthesized compounds were screened for their antitubercular activity using microplate alamar blue assay method and antibacterial activity. Among the tested compounds, 4- fluorophenyl (8m), 4- chlorophenyl (8n) and 4-methoxyphenyl (8i) showed potent anti-TB activity (3.12 µg/mL) in comparison with reference drug, Pyrazinamide ((3.12 µg/mL). In addition, all compounds were docked into DprE1 (PDB code: 4KW5) to explore their binding interactions at the active site. The compounds exhibited essential key interactions as that of reported DprE1 inhibitors and hence, the synthesized compounds may be considered as molecular scaffolds for antitubercular activity. Compounds, 4-chlorophenyl (8n) and 4-flurophenyl (8m) showed significant antibacterial activity against Escherichia coli and Staphylococcus aureus strains. In silico prediction of toxicities, druglikeness and drug score profiles of the tested compounds are promising. Graphical Abstract
VLT Spectroscopy of Blue Supergiants in IC 1613

We present multiobject spectroscopy of young, massive stars in the Local Group galaxy IC 1613. We provide the spectral classification and a detailed spectral catalog for 54 OBA stars in this galaxy. The majority of the photometrically selected sample is composed of B- and A-type supergiants. The remaining stars include early O-type dwarfs and the only Wolf-Rayet star known in this galaxy. Among the early B stars we have serendipitously uncovered six Be stars, the largest spectroscopically confirmed sample of this class of objects beyond the Magellanic Clouds. We measure chemical abundances for nine early B supergiants, and find a mean oxygen abundance of 12 + log (O/H) = 7.90 ± 0.08. This value is consistent with the result we obtain for two H II regions in which we detect the temperature-sensitive [O III] λ4363 auroral line.
Determining of correlation relationship between roll, pitch, and yaw for UAVs

Abstract Currently, UAVs are intensively being introduced into topographic-photogrammetric production for topographic digital aerial photography and laser scanning. These technologies have a number of advantages: they don’t require specially prepared platforms and launchers, they are relatively inexpensive unlike large aircrafts, and they are safe. However, there are still many unsolved problems for ultralight UAVs, especially when the aerial photography is made. As you know, the requirements for the implementation of the aerial survey process are quite stringent, first of all, for horizontal flight: the angles of inclination must be within 3–5 degrees, since exceeding these tolerances significantly affects the accuracy for determining the spatial coordinates of objects. Therefore, there was an idea to conduct researches of dependences between the pitch α, roll ω and yaw κ. For this purpose, 100 images obtained from aircraft-type UAV ‘Arrow’ developed and created by specialists from Lviv Polytechnic National University and ‘Abris’ were used. As a result of the study, the multiple correlation coefficient and the parameters of the linear regression equation for the angular elements of the exterior orientation of digital images were calculated. In addition, statistical quality evaluations for the obtained regression model were carried out. Analysis of the received data allows to assert that angular elements of exterior orientation are correlated with each other. Therefore, in the further imaging materials, processing it becomes possible to make compensation of this fact and to improve calculation accuracy of spatial coordinates of points.
Correlation between serum butyrylcholinesterase activity and serum lipid concentrations in rats treated with different antagonists of the adrenergic system

Background and Purpose: Based on the facts that the blockade of adrenergic receptors can alter lipid profile in the serum and that it has been suggested that butyrylcholinesterase (BuChE) is involved in lipid metabolism, different adrenergic blocking agents were administered to rats to modify lipid concentrations in serum. The activity of BuChE was examined under such conditions and correlations with serum lipids were investigated. The purpose of this study was to evaluate the effects of different adrenergic antagonists on BuChE activity and to investigate the correlation between BuChE activity and serum lipids.
Dural puncture epidural versus conventional epidural block for labor analgesia: a systematic review of randomized controlled trials.

INTRODUCTION Dural puncture epidural analgesia (DPE) is a modification of conventional epidural analgesia that involves the intentional puncture of the dura with a spinal needle through the needle placed in the epidural space, without a medication being injected intrathecally. There have been contradictory findings regarding better analgesia and better block quality. METHODS A systematic literature search was done to identify randomized controlled trials (RCT) comparing DPE with epidural analgesia. The risk of bias was assessed with the Cochrane tool. Risk ratio and 95% confidence intervals were calculated. RESULTS Five RCTs including 581 patients were identified, five reporting on labor analgesia and one on caesarean section. Single studies suggested slightly better analgesia by finding a median time to achieve sufficient analgesia of two minutes less in the DPE group, a higher number of women having a pain score <10/100 at 20 min, a reduction in the number of epidural top-ups and better sacral spread. The studies did not show a difference between DPE and epidural analgesia for catheter replacement or manipulation rates, the incidence of intravascular placement or unilateral block. CONCLUSION There is a lack of clear evidence on either the benefits or therisks of the DPE technique, such that a recommendation for or against its routine use is premature. Two of the three studies showing a beneficial effect of DPE came from the same institution and replication of the findings by other groups is warranted.

Four main therapeutic keys for Parkinson’s disease: A mini review

Objective(s): Parkinson’s disease (PD) is characterized by motor and cognitive dysfunctions. The progressive degeneration of dopamine-producing neurons that are present in the substantia nigra pars compacta (SNpc) has been the main focus of study and PD therapies since ages. Materials and Methods: In this manuscript, a systematic revision of experimental and clinical evidence of PD-associated cell process was conducted. Results: Classically, the damage in the dopaminergic neuronal circuits of SNpc is favored by reactive oxidative/nitrosative stress, leading to cell death. Interestingly, the therapy for PD has only focused on avoiding the symptom progression but not in finding a complete reversion of the disease. Recent evidence suggests that the renin-angiotensin system imbalance and neuroinflammation are the main keys in the progression of experimental PD. Conclusion: The progression of neurodegeneration in SNpc is due to the complex interaction of multiple processes. In this review, we analyzed the main contribution of four cellular processes and discussed in the perspective of novel experimental approaches.
A Review of Field Experiments on the Effect of Forest Bathing on Anxiety and Heart Rate Variability

Many studies have explored the physiological and psychological benefits of the Japanese nature therapy practice of “shinrin-yoku,” known in the West as forest bathing. This review article has narrowed its focus to include the most recent literature about the beneficial effects of forest bathing on heart rate variability, expressed as an increase in InHF, indicating activation of the parasympathetic nervous system and also its effect on reducing anxiety.
Umbilical Cord Mesenchymal Stem Cell Transplantation Prevents Chemotherapy-Induced Ovarian Failure via the NGF/TrkA Pathway in Rats

Chemotherapy leads to a loss of fertility and reproductive endocrine function, thereby increasing the risk of premature ovarian failure (POF). Studies have suggested that the transplantation of mesenchymal stem cells could inhibit apoptosis in ovarian granulosa cells and improve follicular development. In the present study, the effects of human umbilical cord mesenchymal stem cell (UCMSC) transplantation on ovarian function after ovarian damage caused by chemotherapy and the mechanism underlying these effects were investigated. POF model rats were obtained by the intraperitoneal injection of cyclophosphamide, and cultured UCMSCs were transplanted by tail vein injection. Serum estrogen, follicle-stimulating hormone, gonadotropin releasing hormone, and anti-Mullerian hormone levels were detected by ELISA. Folliculogenesis was evaluated by histopathological examination. The expression levels of nerve growth factor (NGF), high affinity nerve growth factor receptor (TrkA), follicle-stimulating hormone receptor (FSHR), and caspase-3 were evaluated by western blotting and RT-qPCR. The natural reproductive capacity was assessed by pregnant rate and numbers of embryos. The results indicated that UCMSC transplantation recovered disturbed hormone secretion and folliculogenesis in POF rats. NGF and TrkA levels increased, while FSHR and caspase-3 decreased. The pregnancy rate of POF rats was improved. Therefore, UCMSCs could reduce ovarian failure due to premature senescence caused by chemotherapy, and the NGF/TrkA signaling pathway was involved in the amelioration of POF.
Genotypes of Helicobacter pylori isolates in Gambian children and adults

Helicobacter pylori is a globally important and genetically diverse gastric pathogen that infects most people in developing countries. Earlier reports indicated high prevalence of H. pylori colonization, but a low frequency of H. pylori-associated diseases in Africa but recent reviews have shown that gastroduodenal disease is actually common in Africa. Most detailed analyses of H. pylori have used strains from non-African countries, despite the high importance of Africa in the emergence and evolution of humans and their pathogens. There have been far fewer critical studies such as genotypes in association with gastric disease, population genetics and antimicrobial resistance and susceptibility of H. pylori strains from Africa. It is with this background that the genotypes of H. pylori in association with gastroduodenal diseases, antibiotic susceptibility to commonly used drugs and population genetics from ethnic African adults and children in The Gambia were investigated. In this study, it was found that the prevalence of H. pylori is high in dyspeptic patients in The Gambia and that many strains were of the putatively more virulent cagA + , vacAs1 and vacAm1 genotypes. There was a high prevalence of cagA positive strains in patients with overt gastric diseases than those with non-ulcerative dyspepsia; conversely, the co-existence of both cagA + and cagA - was found to be protective against the development of gastroduodenal disease. Analyses of the sequenced data with the STRUCTURE software indicated that Gambian H. pylori strains were closely related to hspWAfrica than to strains from more distant African regions (hspSAfrica and hpNEAfrica) indicating common ancestral origin. Essentially no traces of European or North African ancestry were found despite Gambia's history of invasion and colonisation by peoples from these regions during the last millennium. Antibiotic susceptibility tests have shown that Gambian strains were found to be highly sensitive to clarithromycin, erythromycin, tetracycline and amoxicillin but found that more than two-thirds of Gambian H. pylori strains were metronidazole resistant. These data indicate caution in use of metronidazole-based therapies in The Gambia. This thesis provides a detailed initial description of a set of H. pylori isolates directly related to a geographically defined West African population. The data presented has answered some relevant questions on H. pylori virulent genes in association with gastro-duodenal diseases and antibiotic susceptibility providing a comprehensive basis for future studies.
Effect of nucleotides supplementation to low‐fish meal feed on long‐chain polyunsaturated fatty acid composition of juvenile rainbow trout
 Oncorhynchus mykiss

A feeding trial was conducted to evaluate the effect of nucleotides supplementation to low‐fish meal feed on growth and fatty acid composition of rainbow trout. Six isonitrogenous (42% crude protein) and isolipidic (18% crude lipid) diets were formulated containing fish meal and plant ingredients as main protein sources. The control diet was a basal diet without supplementation of nucleotides, and five experimental diets were prepared by supplementing one of the five different nucleotides in the form of 5′‐monophosphate (0.15%), that is inosine (IMP), adenosine (AMP), guanosine (GMP), uridine (UMP) and cytidine (CMP) onto basal diet. Two hundred forty juvenile rainbow trout with an initial average body weight 9.8 g were randomly distributed into twelve aquaria. After 15 weeks of feeding period, growth performance and feed utilization of rainbow trout were not significantly different among dietary treatments. Dietary GMP, UMP and CMP tended to accumulate crude lipid in the muscle and whole fish body. Moreover, dietary GMP, UMP and CMP significantly increased hepatic 18:3n‐3 and long‐chain homologue 18:4n‐3 and 20:4n‐3 contents. Hepatic 18:2n‐6 content showed also increase in fish fed GMP, UMP and CMP diets, but decreased in long‐chain homologue 20:3n‐6 and 20:4n‐6 contents. Decrease in 20:4n‐6, 20:5n‐3 and 22:6n‐3 contents was also found in the muscle of fish fed IMP, GMP and CMP diets. The present study clearly showed that there was no positive effect of dietary nucleotides on growth of fish, but dietary nucleotides particularly GMP, UMP and CMP altered polyunsaturated fatty acid composition of rainbow trout.
Functional genetic characterization by CRISPR-Cas9 of two enhancers of FOXP2 in a child with speech and language impairment

Mutations in the coding region of FOXP2 are known to cause speech and language impairment. Microdeletions involving the region downstream the gene have been also associated to speech and cognitive deficits. We recently described a girl harbouring a complex chromosomal rearrangement with one breakpoint downstream the gene that might affect her speech and cognitive abilities via physical separation of distant regulatory DNA elements. In this study, we have used highly efficient targeted chromosomal deletions induced by the CRISPR/Cas9 genome editing tool to demonstrate the functionality of two enhancers, FOXP2-Eproximal and FOXP2-Edistal, located in the intergenic region between FOXP2 and its adjacent MDFIC gene. Deletion of any of these two functional enhancers in the neuroblastomic cell line SK-N-MC downregulates FOXP2 and decreases FOXP2 protein levels, conversely it upregulates MDFIC and increases MDFIC protein levels. This suggests that both regulatory elements may be shared between FOXP2 and MDFIC. We expect these findings contribute to a deeper understanding of how FOXP2 and MDFIC are regulated to pace neuronal development supporting speech and language.
