Spatially Explicit Inventory of Sources of Nitrogen Inputs to the Yellow Sea, East China Sea, and South China Sea for the Period 1970–2010

Symptoms of eutrophication (including biodiversity loss, harmful algal blooms, and hypoxia) are an increasing problem in Chinese seas. Nutrient enrichment is primarily caused by accelerated human activities that cause nutrient pollution of the aquatic environment. In this study, the Integrated Model to Assess the Global Environment–Global Nutrient Model (IMAGE‐GNM) was used to estimate nitrogen inputs from river discharge, submarine fresh groundwater discharge, and mariculture, and TM5‐FAst Scenario Screening Tool (TM5‐FASST) for atmospheric nitrogen deposition to the three Large Marine Ecosystems (LMEs, i.e., Yellow Sea/Bohai Sea, YS/BS; East China Sea, ECS; South China Sea, SCS) bordered by China and several other countries for the period 1970–2010. China's river nitrogen export was the largest nitrogen source in YS/BS and ECS. In SCS, however, China and other countries contributed equally and although decreasing, the proportion of natural sources remain considerable. The total nitrogen inputs to YS/BS (1.0 to 4.1 Tg year−1), ECS (1.3 to 5.5 Tg year−1), and SCS (2.1 to 5.8 Tg year−1) increased rapidly during 1970–2010. River export is dominated by agriculture; nitrogen inputs from atmospheric deposition and mariculture have been increasing rapidly in recent years. Considering only the coastal zone of the three LMEs, our results show that the total nitrogen inputs are strongly concentrated spatially in areas close to river mouths and those confined regions with mariculture production. To sustain the food production and economic growth in the coming decades, nitrogen inputs may increase further, depending on future eutrophication mitigation policies.
Phenethyl Esters and Amide of Ferulic Acid, Hydroferulic Acid, Homovanillic Acid, and Vanillic Acid: Synthesis, Free Radicals Scavenging Activity, and Molecular Modeling as Potential Cholinesterases Inhibitors

As ferulic acid was reported to be involved in novel potential mechanisms associated with Alzheimer’s disease (AD) therapy, five closely related phenethyl esters and amide of this natural product were synthesized and screened for their free radicals scavenging activity. Ferulic acid and its analogue′s absorption, distribution, metabolism, and excretion (ADME) properties were predicted. All compounds obey Lipinski′s rules. Moreover, all evaluated compounds seem to present a high oral bioavailability and blood–brain barrier (BBB) permeation which is crucial for Alzheimer′s disease drug candidates. Molecular docking of analogues 4 and 8 with acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) showed interactions with the residues of the catalytic triad of AChE and BChE. In addition to their interactions with the anionic subsite, hydroferulic acid phenethyl ester 4 and homovanillic acid phenethyl ester 8 may have potential as inhibitors of AChE and BChE, respectively.
Towards an increased understanding of reminiscence therapy for people with dementia: A narrative analysis

Aim Reminiscence therapy is a popular therapeutic intervention for people with dementia. This review set out to provide a better understanding of reminiscence therapy through a deeper analysis of its contents and delivery. Method This review examined 22 studies from the most recent Cochrane review (Woods, B., O’Philbin, L., Farrell, E. M., Spector, A. E., & Orrell, M. (2018). Reminiscence therapy for dementia. Cochrane Database of Systematic Reviews, 3, Article 001120) and addressed the following research questions: (1) What are the components of reminiscence therapy? (2) Who delivers reminiscence therapy? (3) How is reminiscence therapy delivered? (4) Is reminiscence therapy underpinned by a theoretical framework? (5) Is reminiscence therapy delivered according to a programme/model? (6) Are there commonalities in the reminiscence therapy components utilised? Multiple and layered narrative analyses were completed. Findings Thirteen reminiscence therapy components were identified. ‘Memory triggers’ and ‘themes’ were identified as the most common but were found not to be consistently beneficial. Reminiscence therapy was typically delivered in a care setting using a group approach; however, there was no consistency in session composition, intervention duration, as well as the training and supervision provided to facilitators. Operationalisation of theory within reminiscence therapy was not identified. Reminiscence therapy was not consistently delivered according to a programme/model. Lastly, as a result of a small number of studies, the components ‘life stages’, ‘activities’ and ‘family-only sessions’, showed beneficial promise. In summary, this review highlights that reminiscence therapy needs more consistency in content and delivery, in addition to a clear theoretical framework.
ASSESSING THE STRATIGRAPHIC INTEGRITY OF PLANKTIC AND BENTHIC 14C RECORDS IN THE WESTERN PACIFIC FOR Δ14C RECONSTRUCTIONS AT THE LAST GLACIAL TERMINATION

ABSTRACT There is a growing database of radiocarbon (14C) reconstructions from biogenic carbonate taken from marine sediment cores being used to investigate changing ocean circulation and carbon cycling at the end of the last great ice age. Reported here are 14C results from a marine core taken in the Makassar Straits of the western equatorial Pacific that was intended to test whether there was evidence of geologic carbon release to the ocean during the glacial termination. A thorough investigation of planktic and benthic 14C ages with stable isotopes and CT-scans revealed extensive burrowing in the upper 2 m of the core that displaced younger sediments downward by more than half a meter into the glacial section of the core. The vertical displacement is evident in both planktic and benthic fossils. However, the extent of displacement and the stratigraphic disturbance became evident only after multiple measurements of different species and genera. A CT-scan prior to sampling would be an effective screening tool to avoid sampling problem cores such as this.
Advancements in Real-Time Simulation for the Validation of Grid Modernization Technologies

Real-time simulation and hardware-in-the-loop testing have increased in popularity as grid modernization has become more widespread. As the power system has undergone an evolution in the types of generator and load deployed on the system, the penetration and capabilities of automation and monitoring systems, and the structure of the energy market, a corresponding evolution has taken place in the way we model and test power system behavior and equipment. Consequently, emerging requirements for real-time simulators are very high when it comes to simulation fidelity, interfacing options, and ease of use. Ongoing advancements from a processing hardware, graphical user interface, and power system modelling perspective have enabled utilities, manufacturers, educational and research institutions, and consultants to apply real-time simulation to grid modernization projects. This paper summarizes various recent advancements from a particular simulator manufacturer, RTDS Technologies Inc. Many of these advancements have been enabled by growth in the high-performance processing space and the emerging availability of high-end processors for embedded designs. Others have been initiated or supported by developer participation in power industry working groups and study committees.
Effect of bamboo and neem charcoal micro particles application on the anti bacterial and UV protection properties of woven fabrics

Abstract Textiles are considered to be an integral part of human life, since they are associated with the human body round the clock. Because of the various application of textiles in several fields, it is obvious that, people will expect functional characteristics such as comfort, healthcare, hygiene properties in clothing. The healthcare characteristics were also much expected in clothing to protect the human being from the adverse effects of outside environment resulting in infections and various diseases. The bacterial and viral infection is a common phenomenon in human’s life causing much number of diseases from fever to major malfunctioning of important body parts. Hence this research work is focused specifically on identifying new approaches with the aid of technological advancements. This work aims at investigating the above-mentioned characteristics through developing natural based treatments such as charcoal applications with a specific focus on hygiene properties as their effects. The charcoal treated fabrics were also subjected to hygiene tests such as antibacterial and UV protection (UV Protection Factor, UPF) and have been found that the treated fabrics have developed antibacterial and UV protection properties.
Cross-modal Center Loss

Cross-modal retrieval aims to learn discriminative and modal-invariant features for data from different modalities. Unlike the existing methods which usually learn from the features extracted by offline networks, in this paper, we propose an approach to jointly train the components of cross-modal retrieval framework with metadata, and enable the network to find optimal features. The proposed end-to-end framework is updated with three loss functions: 1) a novel cross-modal center loss to eliminate cross-modal discrepancy, 2) cross-entropy loss to maximize inter-class variations, and 3) mean-square-error loss to reduce modality variations. In particular, our proposed cross-modal center loss minimizes the distances of features from objects belonging to the same class across all modalities. Extensive experiments have been conducted on the retrieval tasks across multi-modalities, including 2D image, 3D point cloud, and mesh data. The proposed framework significantly outperforms the state-of-the-art methods on the ModelNet40 dataset.
Facemask detection using Deep Learning

COVID-19 was raised in the year 2020 which became more dangerous to society. According to the medical results, 100 million confirmed cases and 6 million deaths. This virus became an obstacle to gathering people in public places. This virus has spread all over the world. So, the Government has implemented a facemask policy to prevent the hazardous virus. It is a very difficult task to observe manually in crowded places. Most people are not wearing facemasks properly in public a place which causes the increase of the virus. So, the proposed model will detect the face mask whether the people are wearing it or not. By using, the HAAR-CASCADE technique we can able to detect whether the people are wearing the mask or not. By using this algorithm, we can able to prevent affecting of the virus to the person. This algorithm works effectively for detecting facemasks. The system compares faces with masks and faces without the mask. If people are not wearing a mask, the system detects through the camera and alerts by the alarm sound. The experiment results show the proposed technique achieves a 95% accuracy rate.
Detecting Looting Activity through Earth Observation Multi-Temporal Analysis over the Archaeological Site of Apamea (Syria) during 2011–2012

This study aims to investigate the potentials of open-access, freely distributed Earth Observation images for detecting large-scale looted areas. The analysis was conducted using medium-resolution Landsat 7 ETM+ images over the archaeological site of Apamea, at Syria. The site has been systematically and extensively looted in the recent past, attracting the interest of scholars. We propose a multi-temporal analysis of cloud-free multispectral Landsat 7 ETM+ images throughout the period between January 2011 to April 2012, just at the beginning of the Syrian war. The analysis was completed through the interpretation of pseudo-color temporal composites, investigation of the multi-temporal spectral profiles, correlations between the spectral bands, and the application of principal component analysis (PCA). The overall analysis was limited within the spectral range of 450–1750 nm. This wavelength range corresponds to the first five spectral bands of the Landsat images. Furthermore, we explored the big data cloud platform Google Earth Engine to detected looted areas. A supervised classification strategy was designed and performed on this cloud platform employing the Random Forest classifier. Finally, a time-stamp change detection approach was implemented. The overall findings were compared with available images from Google Earth Digital Globe and published articles and reports related to the Apamea archaeological site. It was found that the high revisit temporal resolution of the Landsat sensor was able to detect and map the looting activity in the area as a result of the spectral change in the archaeological landscape, despite its 30 m spatial resolution. At the same time, however, the analysis has provided other false-true detections in other areas in the landscape.
Bringing Jobs To People: Improving Local Economic Development Policies

Many local labor markets in the United States suffer from low employment rates, but getting people to move out of these distressed areas is difficult. Moreover, moving people to jobrich regions does not help those left behind, as out-migration destroys jobs in distressed areas. A better way to help the residents of distressed areas is through local economic development policies that boost job growth and employment rates in a sustained fashion. Such policies can successfully encourage local business and job growth through business tax incentives, cash grants, or customized public services, such as advice to small businesses, job training, infrastructure development, or development-ready land. However, there is scope for improvement in how local economic development policies are carried out. I highlight the need for approaches that increase the benefits per job created by better targeting job creation to distressed areas and using workforce programs to link unemployed workers with jobs. There are also ways that local development policies could have a lower cost per job created. For instance, tax incentives and cash grants to a few large projects are less cost-effective in creating jobs than providing a broader array of businesses with public services. Needed reforms to local economic development policies are within the power and resources of state and local governments to accomplish on their own. However, federal intervention could potentially help by capping some of the largest incentives, and by providing distressed areas with funding to carry out their development plans.
Martín and the pink crayon: peer language socialization in a kindergarten bilingual classroom

ABSTRACT This paper addresses the interactional dynamics of one bilingual, two-way immersion classroom where children came from diverse linguistic, cultural, racial, and socioeconomic backgrounds. Based on an ethnographic discourse analytic study of one kindergarten TWI classroom, I analyze interactional data using participant frameworks as the unit of analysis and develop a linguistic analysis from a language socialization lens. Findings illustrate the ways that children’s talk and communicative behaviors act as peer socializing processes as children move in and out of various participatory roles in conversation. By virtue of their intentional spatial positioning around communal tables, students are socializing each other as participants into a bilingual learning community, even when they are silent participants or overhearers. I argue that this framework is a productive lens through which to analyze bilingual multiparty conversations in a way that does not privilege linguistic codes as a basis for analysis.
A Comprehensive Method of Ion Exchange Resins Regeneration and Its Optimization for Water Treatment

Ion exchange membranes, specifically resin technology, lie at the heart of electrolytically conductive systems used in the treatment of wastewater. This chapter deals with ion exchange deionization and the effect of resin amount as well as the concentration of acid and base on the product conductivity. The strong acidic cation polymeric exchanger resin is commercially called MERCK 104765 cation exchanger IV with capacity greater than 3.2 mmol/ml, while the strong basic anion polymeric exchanger resin is commercially called MERCK 104767 anion exchanger III with capacities greater than 1.0 mmol/ml. Water conductivity, as an indicator of regeneration efficiency, was monitored over time at the different conditions and scenario. In general, it was observed that the conductivity decreases with time until one point is reached and then starts to increase as a result of resin saturation. It was also noticed that the lowest conductivity is achieved when using 1-vol% NaOH and 5-vol% HCl in the cathodic and anodic resin tubes, respectively, and that water conductivity increases with the increase in the amount of water being used. The amount of resin significantly impacts the deionization efficiency; more ions are removed as the amount of resin increases.
Silver speciation in seawater: the importance of sulfide and organic complexes

The effect of variations in pH, salinity, sulfide and dissolved organic carbon (DOC) concentrations on the speciation of dissolved Ag were calculated using the MINTEQ geochemical model. Molecular-weight-averaged conditional equilibrium constants for natural Ag-organic complexes were estimated from the equilibrium constants for specific metal-organic complexes and the concentration of the organic compounds, reported to be present in seawater, summed by principal functional group. These calculations show that the major Ag complexes in seawater are AgHS/sup 0/, for S(-II) concentrations above 0.01 . mu.g L/sup -1/, AgCl/sup 0/, AgCl/sub 2//sup -/, AgCl/sub 3//sup -/ and AgCl/sub 4//sup 0/. If the AgCl/sup 0/ complex is the primary bioavailable or toxic chemical species as has been reported, the toxicity of silver will decrease significantly with increased S(-II) concentration, pH, and with decreased salinity. Organically complexed silver was calculated to represent <1% of the total dissolved Ag, which suggests that changes in Ag speciation previously attributed to DOC complexation may actually be due to formation of S(-II) or sulfhydral complexes. 42 references, 6 figures, 5 tables.
Smart campus system using internet of things: simulation and assessment of vertical scalability

Background/Objectives: Scalability in the Internet of Things is meant for future extension in Internet connected devices. The scalability can be classified into two broad sense in terms of future flexibility i.e., vertical and horizontal scalability and in terms of infrastructure of the Internet of things i.e., device, communication, gateway, and server levels. Novelty: In this article, a novel taxonomy of scalability is proposed and presented according to infrastructure and it is categorized into four levels i.e., device, gateway, communication,and server levels. Moreover, a performance analysis of vertical scalability is conducted at the server level for a smart campus transportation system on a custom-based emulator developed in Visual Studio. Findings: From the results,it is observed that by increasing the load the response time of the server increases. And by scaling up, response time decreases. By scaling up at a certain limit and increasing the load, response time again increases. It is strongly believed that this research will help in assessing the capacity of present and future smart systems. Keywords: Internet of things; vertical scalability; horizontal scalability; smart campus; smart transport system
Synthèse et caractérisation de nanocomposites à base de ZnO pour des applications thermoélectriques

Ce travail de these a pour objectif l’obtention de nanocomposites denses ZnO/SiO2 afin d’ameliorer les proprietes thermoelectriques de l’oxyde de zinc. Ce manuscrit decrit differents aspects de l’elaboration tant en terme de synthese que de densification de nanocomposites ZnO/SiO2 ainsi que leur caracterisation. Afin d’obtenir des nanoparticules en grande quantite, de bonne cristallinite et de taille inferieure a 10 nm, l’optimisation d’une synthese par voie polyol en jouant sur differents parametres (pH, temperature, taux d’hydrolyse, solvant, surfactant) a ete realisee. Nous avons pu mettre en evidence l’interet d’utiliser l’acide benzoique comme surfactant pour eviter l’agglomeration de ces nanoparticules. La modification de surface des nanoparticules par de la silice a ensuite ete exploree. Cette modification a ete realisee par une methode classique, le procede Stober, ainsi que par une technique moins conventionnelle, l’ALD. Une etude approfondie de la densification par SPS a la fois de l’oxyde de zinc et des nanoparticules recouvertes a ete decrite. L’influence de la couche amorphe deposee sur la croissance cristalline des nanoparticules a ete demontree. Nous avons par ailleurs pu mettre en exergue une pollution importante par du carbone lors de la densification des composes entrainant des modifications importantes des proprietes de transport. Le resultat majeur de cette these est la mise en evidence de clusters d’oxyde de zinc fortement dopes dans ces composes qui remet en question les mecanismes de transport dans le ZnO.
Hysteroscopic removal of retained products of conception withenhanced vascularity: a study of reliability

Purpose of Investigation: Retained products of conception (RPOC) is the leading cause of postpartum or post-abortion hemorrhage. RPOC showing high vascularity at ultrasound assessment (HV-RPOC) showed an enhanced hemorrhagic risk following blind surgical uterine emptying. The authors describe the clinical outcome of patients suffering from HV-RPOC undergoing hysteroscopic removal. Material and Methods: Cohort of symptomatic patients suffering from HV-RPOC following miscarriages, pregnancy terminations, and term deliveries. After ultrasound selection based on color-Doppler showing HV-RPOC, all patients underwent hysteroscopic resection. Results: Twenty-seven patients met the selection criteria. HV-RPOC were found in 14 and six women after first and second trimester pregnancy termination, respectively. In seven women RPOC were found after term delivery. In 18 women (66.6%) RPOC were found firmly adherent to myometrium. Neither intranor postoperative complications were recorded. Hysteroscopy follow-up was carried-out in 16 patients. Normal findings were found in 15 women, in one case a mild adhesion was observed. Conclusion: HV-RPOC are often characterized by abnormally adherent placenta, suggesting that an accreta can be an underlying etiology. A reliable management can be accomplished by hysteroscopic resection.
