Abstract Background. Acute transfusion reactions (ATR) have been attributed to antibodies directed against HLA antigens in platelet components (PLT). Cytokines and chemokines, released from PLT during storage are postulated to mediate ATR, clinical refractoriness, and graft vs. host disease. Reduced plasma levels and leuko-depletion of PLT lower the frequency of some, but not all, ATR and allo-immunization. Among platelet factors, soluble CD40L (sCD40L) plays a key role in immunology. CD40/CD40L are strongly expressed by activated platelets and CD40L is cleaved to sCD40L. More than 95% of sCD40L in blood is derived from platelets. CD40 is a major regulator of cellular immune interactions and CD40L stimulates monocytes and T cells, suggesting a pleiotropic role for CD40L. Prior studies suggest sCD40L with other mediators are responsible for ATR, especially fever. Aims. As part of a safety study to monitor ATR for PLT prepared with pathogen inactivation, we identified transfusions associated with ATR. Implicated PLT were sampled to characterize cytokine/chemokine profiles in comparison to PLT not associated with ATR(control). Methods. PLT were collected by apheresis at the Mont Godinne Blood Transfusion Center (BTCMG) with process leuko-reduction, suspended in 35% donor plasma and 65% additive solution (Intersol, Baxter, France) and treated with 150uM amotosalen and 3 J/cm2 UVA for pathogen inactivation (INTERCEPT, Cerus, Concord, CA). Treated PLT were stored up to 7 days until issued for transfusion. Transfusion of PLT required completion of a case report form to monitor the response to transfusion. PLT implicated in ATR were sampled to determine cytokine profiles. Frozen samples (−20 °C) of PLT were sent to EFS Auvergne Loire to assay CD62p(ng/mL), PDGF-AB(ng/mL), IL8(pg/mL), and sCD40L(pg/mL) by specific enzyme linked immunosorbent assays in platelets (plt) and supernatant (s) fractions isolated from the implicated PLT. Cytokine levels in PLT without ATR (Control) were measured in 10 PLT after 5 and 7 days of storage (5d CTL; 7d CTL). Results. In the 18-months after adoption of INTERCEPT PLT compared to the 18-months prior, ATR decreased from 1.3% to 0.9% of transfusions (n = 7,580: Blood2005;106(11):29a). After initiation of the current study, 4 transfusions with ATR had samples available: one with 4-day old PLT (0451) and 3 with 7-day old PLT (0715, 0561, 0536). Supernatants of PLT implicated in ATR contained higher sCD40L levels compared to Control PLT (Table). Increased sCD40L levels in supernatants of PLT implicated in ATR correlated with decreased levels in plt lysates. Levels of IL8, CD62p and PDGFAB, were similar to Control values. Conclusions. In this pilot study, sCD40L was elevated in supernatants and decreased in the platelets of PLT associated with ATR. Other cytokines (CD62p, PDGF, and IL8) were not consistently altered in PLT implicated in ATR.

Abstract. Direct-reading gas monitors warn workers of the risk of potentially fatal hydrogen sulfide (H2S) exposures that may arise during manure handling. Low-cost, low-maintenance H2S monitors are available from many manufacturers, but differences in their features and performance make selection challenging for farmers. Moreover, little information is available on the practical maintenance and performance of these devices in agricultural environments. The objective of this study was to provide information to agricultural workers to aid in the selection, maintenance, and use of low-cost H2S monitors. This laboratory study evaluated the performance of several low-cost monitors over a simulated period of use of one year in a swine barn. Four models were exposed to H2S concentrations of 1 to 10 ppm over 18 weeks to examine the drift in reported concentration and changes in the alarm reaction time. Over the simulated barn year, the performance of alarm-only monitors declined faster than that of monitors displaying the H2S concentration. Of concern was the high-level (20 ppm) alarm failures after an equivalent of 139 days (Altair) and 289 days (BW Clip) in a swine barn, well within the monitor’s reported shelf-life. Models displaying concentration exhibited fewer failures but were inaccurate in the displayed concentration when challenged with 20 ppm of H2S. The T40 Rattler provided consistently higher readings (+2.3 ppm), and the Pac 3500 showed consistently lower readings (-3.4 ppm) when challenged with 20 ppm. This study confirms the need for routine bump tests for these low-cost monitors to ensure that the monitor reacts to the presence of H2S, even if the manufacturer does not recommend this procedure. Most importantly, agricultural workers should inspect and bump test these monitors prior to any potentially high-risk activity, such as manure agitation, pumping, or pressure washing, to ensure that the monitor appropriately detects and warns users.

Full textAbstract:
An innovative approach currently is underway in Kansas to estimate and monitor constituent concentrations in streams. Continuous in-stream water-quality monitors are installed at selected U.S. Geological Survey stream-gaging stations to provide real-time measurement of specific conductance, pH, water temperature, dissolved oxygen, turbidity, and total chlorophyll. In addition, periodic water samples are collected manually and analyzed for nutrients, bacteria, and other constituents of concern. Regression equations then are developed from measurements made by the water-quality monitors and analytical results of manually collected samples. These regression equations are used to estimate nutrient, bacteria, and other constituent concentrations. Concentrations then are available to calculate loads and yields to further assess water quality in watersheds. The continuous and real-time nature of the data may be important when considering recreational use of a water body; developing and monitoring total maximum daily loads; adjusting water-treatment strategies; and determining high constituent concentrations in time to prevent adverse effects on fish or other aquatic life.

Full textAbstract:
Real-time electronic adherence monitoring involves “smart” pill boxes that record and monitor openings as a proxy for pill taking and may be useful in understanding and supporting PrEP use; however, acceptability and/or feasibility for PrEP users is uncertain. We sought to understand the experiences of using a real-time electronic adherence monitor for PrEP delivery among young women in Kisumu and Thika, Kenya. We used the Wisepill device to monitor PrEP use among 18-24-year-old women for two years. Half of the participants were randomized to also receive SMS adherence reminders (daily or as needed for missed doses). We assessed acceptability quantitatively and qualitatively according to the four constructs of Unified Theory of Acceptance and Use of Technology (UTAUT): performance expectancy, effort expectancy, social influence, and facilitating conditions. We assessed feasibility by monitor functionality during periods of PrEP use. We analyzed quantitative data descriptively and compared by site and over time; qualitative data were analyzed inductively and deductively. The median age was 21 years (IQR 19–22), median education was 12 years (IQR 10–13), 182 (53%) had disclosed PrEP use, and 55 (16%) reported recent intimate partner violence. Most participants reported high levels of usefulness and high interest in using the monitor with few problems or worries reported throughout follow-up. Feasibility was high overall with some differences by site (96% functional monitor days in Kisumu vs 88% in Thika). Few monitors were reported lost (N = 29; 8%) or dysfunctional (N = 11; 3%). In qualitative interviews, electronic monitoring was perceived as useful because it supported privacy, confidentiality, easy storage, and PrEP adherence. Effort was generally considered low. Participants expressed some concern for stigma from monitor and/or PrEP use. Facilitating conditions involved the monitor size, color, and battery life. Overall, real-time electronic adherence monitoring was a highly acceptable and feasible approach to understand PrEP adherence among young women in a sub-Saharan African setting.

Full textAbstract:
In the past few years, technical progress has determined traditional electric power system conversion to Smart Grids, and consequently empowered a worldwide renaissance in the forgotten PQ field. Since the installation of PQ monitors is currently associated with high investments and operational costs, it is inappropriate to install a monitor on each grid busbar. Hence, grid operators must establish the best cost–benefit scenario for monitors installation and achieve maximal observability with a limited number of analyzers. Firstly, this paper presents a review of the state-of-the-art of displacement strategies, and discusses them regarding the tendencies of node selection criteria, the test schemes used, and the grid size. Secondly, the relevant fundamental issues which must be solved in the future in order to eliminate restrictions in PQ monitors’ allocation planning are presented and discussed. These issues concern the treatment, interpretation, and assessment of PQ events, measurement chain technical features, PQ’s role in the grid planning stage, communication technologies, and other remote monitoring aspects, and integration with other Smart Grid applications. The provided insights are based on experience which has been obtained during the PQ measurement campaign in the Lithuanian DSO grid. Finally, a PQ system development strategy—both short-term and long-term perspectives—in the Lithuanian distribution grid is presented, including monitors allocation criteria.

Full textAbstract:
Background. Seizures are frequent in ICU and their diagnosis is challenging, often delayed or missed. Their diagnosis requires a conventional EEG recording. When cEEG is not available, there is no consensus on how patients should be monitored when there is high risk of seizure. This case illustrates how a bispectral index monitor allowed an early diagnosis of an NCSE recurrence. Case Presentation. A NCSE was diagnosed at the admission. cEEG was not available and then a bispectral index (BIS) monitor was placed and processed parameters were monitored as usual. During the first and second day, both conventional and BIS’s EEG showed patterns of burst suppression and the BIS value varied between 25 and 35 while the suppression ratio (SR) varied between 20 and 35. On the third day, while hypnotic drugs were withdrawn progressively, raw EEG of the BIS monitor showed spikes, spikes waves, and polyspikes without significant variation of BIS and SR values. Even if processed parameters stayed between their usual ranges, the typical aspect of the real time EEG raised concern for NCSE recurrence. An unplanned conventional EEG recording was urgently requested, and the diagnosis was confirmed and treated. Conclusion. Primitive and secondary brain injuries can lead to seizures which are often purely electrical. Even though BIS monitors cannot substitute the conventional EEG, processed parameters and raw EEG should be always analysed jointly. In the present case, seizure was suspected only on the aspect of real time EEG which showed spikes, spikes waves, and polyspikes.

Evidence from the Italian say-on-pay." Corporate Ownership and Control 14, no. 4 (2017): 41–57. http://dx.doi.org/10.22495/cocv14i4art4.
Full textAbstract:
Where corporate ownership is concentrated, the incentives for institutional shareholders to engage with firms in their portfolio are not clear a priori. Making use of a unique dataset of Say-on-Pay (SOP) votes in Italian listed firms, we provide evidence that specific classes of institutional investors do actively monitor investee firms under concentrated ownership, and that Proxy Advisors (PAs) perform an informational role: i) while general shareholder dissent on SOP is low, dissent by mutual and pension funds holding small equity positions (nonblockholders) is high; ii) nonblockholders’ dissent is negatively correlated with ownership concentration, suggesting that they tend to trust control shareholders to act as delegated monitors on managerial remuneration; iii) voting by institutional investors is strongly correlated with PA recommendations; iv) institutional investors do not follow PA recommendations blindly but look at specific reasons of concern expressed in PA reports. Our results may have relevant policy implications.

It was predicted that high self-monitors experience self-presentational conflicts whereas low self-monitors experience self-congruence conflicts. It was also predicted that low self-monitors who were Machiavellian would experience self-presentational conflicts like their high self-monitoring counterparts. Participants read eight scenarios involving social conflicts in four different contexts and indicated which of two conflicts in each scenario they themselves would experience. Participants were then classified as high or low in self-monitoring and in Machiavellianism. Although there was an unexpected prevalence of self-congruence conflicts, the results were consistent with our hypotheses. Alternative explanations and future research directions are discussed.

Citizen science mosquito surveillance has been growing in recent years due to both increasing concern about mosquito-borne disease and the increasing popularity of citizen science projects globally. Health authorities are recognising the potential importance of citizen science to expanding or enhancing traditional surveillance programs. Different programs have shown success in engaging communities to monitor species of medical importance through low-cost methods. The Mozzie Monitors project was established on iNaturalist—an open citizen science platform that allows participants to upload photos (i.e., observers) and assist identification (i.e., identifiers). This article describes the likelihood of citizen scientists submitting photos of mosquitoes, assesses user submission behaviour, and evaluates public health utility from these citizen science-derived data. From October 2018 to July 2021, the Mozzie Monitors project on iNaturalist received 2118 observations of 57 different species of mosquitoes across Australia. The number of observers in the system increased over time with more than 500 observers and 180 identifiers being active in the project since its establishment. Data showed species bias with large-bodied and colourful mosquitoes being over-represented. Analyses also indicate regional differentiation of mosquito fauna per state, seasonality of activity, and ecological information about mosquitoes. The iNaturalist citizen science platform also allows connectedness, facilitated communication and collaboration between overall users and expert entomologists, of value to medical entomology and mosquito management.

Full textAbstract:
Purpose – The purpose of this paper is to raise awareness of the importance for library and information services (LIS) to take the responsibility to find a manageable way to regularly monitor internet censorship in their countries, and to suggest a framework for such monitoring and to encourage manageable on-going small scale research projects. Design/methodology/approach – The paper follows on contract research for the IFLA Committee on Freedom of Access to Information and Freedom of Expression on country specific trends in internet censorship. Based on an extensive literature survey (not fully reflected here) and data mining, a framework is suggested for regular monitoring of country specific negative and positive trends in internet censorship. The framework addresses search strategies and information resources; setting up alerting services; noting resources for data mining; a detailed break-down and systematic monitoring of negative and positive trends; the need for reflection on implications, assessment of need(s) for concern (or not) and generation of suggestions for actions; sharing findings with the LIS community and wider society; and raising sensitivity for internet censorship as well as advocacy and lobbying against internet censorship. Apart from monitoring internet censorship, the framework is intended to encourage manageable on-going small scale research. Findings – A framework of internet censorship monitoring can support the regular, systematic and comprehensive monitoring of known as well as emerging negative and positive trends in a country, and can promote timely expressions of concerns and appropriate actions by LIS. It can support sensitivity to the dangers of internet censorship and raise LIS’ levels of self-efficacy in dealing with internet censorship and doing manageable, small scale research in this regard. Originality/value – Although a number of publications have appeared on internet censorship these do not offer a framework for monitoring internet censorship and encouraging manageable on-going small scale research in this regard.

Full textAbstract:
With the impending release of Edition 2 of the International Electrotechnical Commission (IEC) Standard 61511 in Australia, it is timely to revisit the topic of safety instrumented system (SIS) performance monitoring. Operators need to monitor the performance of their SISs to ensure that design assumptions are correct. Any incorrect assumption or error introduced during operation can result in an unsafe plant situation. Questions to consider include: how do operators know their plants are adequately protected; are protection systems performing as required, and do operators need to re-assess the safety of their plant’s process vis-à-vis the implemented safety instrumented systems; what are end-user obligations; how and is it possible to meet these obligations; and what additional requirements are there, and how much more prescriptive is Edition 2? If any of the above questions are of concern, or if plant personnel are aware of their obligation to maintain and monitor the SIS during operations but are still not 100% sure if they are on the right track or need to do more, then this paper will prove useful. In addition to knowing all the requirements to comply, actual implementation and maintenance of a program to monitor the performance of SIS can prove overwhelming. Not only do you need to be adept in maintaining a database, but you also need to understand how to consolidate various critical information sources in order to make sense of all the data collected. Fortunately, there are solutions in the market to help end-users overcome these hurdles to effectively monitor SIS performance. This paper looks at some key areas that a complete solution should cover and what some of the features of such a solution are.

Abstract Background Preventing the transmission of multidrug-resistant organisms requires strict adherence to isolation precautions. Candida auris (CA), an emerging multidrug-resistant fungal pathogen, can cause widespread and persistent contamination of environmental surfaces within healthcare facilities and lead to outbreaks. While direct observation (DO) with “secret shoppers” is traditionally used to monitor adherence to isolation precautions and personal protective equipment (PPE) use by healthcare personnel (HCP), this method is limited by logistic and cost issues. We studied the use of remote video auditing (RVA) to monitor adherence to isolation precautions in a patient with CA fungemia. Methods This is a cross-sectional study of HCP who were in contact with a single patient with CA fungemia. This patient was placed on standard and contact precautions and held in isolation in a single room in an acute care setting. Adherence to isolation precautions by HCP was observed by DO and RVA. RVA consisted of recording videos of HCP entering and exiting the room and auditing adherence using a standardized protocol by remotely-placed observers. Hand hygiene (HH) on entry and exit, the use of gloves and gowns upon entry, correct gown donning and the proper doffing sequence upon exit were observed by both methods. In the DO method, data were recorded per visit and not by entry/exit. Results RVA captured data for 120 visits by HCP (entry data [n = 62]; exit data [n = 58]) and DO captured data for 173 visits by HCP during 23 days. Table 1 shows the compliance rates determined by both methods. RVA yielded lower compliance rates on most measures than the DO method. Also, there were a higher number of missing observations in the DO group Conclusion RVA, when used to monitor adherence to isolation precautions in a high-concern CA patient, demonstrated lower compliance rates compared with DO and had fewer missing data elements. These results suggest that RVA is a novel monitoring method that may be a more precise alternative to DO for ensuring adherence to isolation precautions and the prevention of nosocomial transmission of high-concern pathogens such as CA.

Full textAbstract:
Chiropterans are important mammals of conservation concern across Neotropical regions, facing a number of threats, including increasing levels of urbanization, leading to habitat loss. Despite this, many species of bats regularly utilize a variety of roosting sites, including both natural and man-made structures. Methods for monitoring bat populations include citizen science applications. The roosting habits of tropical bats has seldom been assessed on the most widespread citizen science app, iNaturalist. To this end, I characterized images of observations of bats in Panama. I report on 344 observations, with 59.9% roosting in natural habitats versus 29.6 % roosting in man-made environments, respectively. The most commonly observed species include Rhynchonycteris naso, Uroderma bilobatum, and Artibeus jamaicensis. Total observations increased annually, indicating the potential for future conservation monitoring. I recommend bat researchers utilize iNaturalist as a tool to study roosting selection and habitat use by bats, as this application is likely to increase in use.

Full textAbstract:
Cyanobacterial harmful algal blooms (CHABs) have been a concern for aquatic systems, especially those used for water supply and recreation. Thus, the monitoring of CHABs is essential for the establishment of water governance policies. Recently, remote sensing has been used as a tool to monitor CHABs worldwide. Remote monitoring of CHABs relies on the optical properties of pigments, especially the phycocyanin (PC) and chlorophyll-a (chl-a). The goal of this study is to evaluate the potential of recent launch the Ocean and Land Color Instrument (OLCI) on-board the Sentinel-3 satellite to identify PC and chl-a. To do this, OLCI images were collected over the Western part of Lake Erie (U.S.A.) during the summer of 2016, 2017, and 2018. When comparing the use of traditional remote sensing algorithms to estimate PC and chl-a, none was able to accurately estimate both pigments. However, when single and band ratios were used to estimate these pigments, stronger correlations were found. These results indicate that spectral band selection should be re-evaluated for the development of new algorithms for OLCI images. Overall, Sentinel 3/OLCI has the potential to be used to identify PC and chl-a. However, algorithm development is needed.

Full textAbstract:
Nearly two years since the start of the SARS-CoV-2 pandemic, which has caused over 5 million deaths, the world continues to be on high COVID-19 alert. The World Health Organization (WHO), in collaboration with national authorities, public health institutions and scientists have been closely monitoring and assessing the evolution of SARS-CoV-2 since January 2020. The emergences of specific SARS-CoV-2 variants were characterized as Variant of Interest (VOI) and Variant of Concern (VOC), to prioritize global monitoring and research, and to inform the ongoing global response to the COVID-19 pandemic. The WHO and its international sequencing networks continuously monitor SARS-CoV-2 mutations and inform countries about any changes that may be needed to respond to the variant, and prevent its spread where feasible. Multiple variants of the virus have emerged and become dominant in many countries since January 2021, with the Alpha, Beta, Gamma, Delta and Omicron variants being the most prominent to date. The paper was aimed to review the SARS-CoV-2 variants of concern (VOC).

Full textAbstract:
Background New consumer health devices are being developed to easily monitor multiple physiological parameters on a regular basis. Many of these vital sign measurement devices have yet to be formally studied in a clinical setting but have already spread widely throughout the consumer market. Objective The aim of this study was to investigate the accuracy and precision of heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and oxygen saturation (SpO2) measurements of 2 novel all-in-one monitoring devices, the BodiMetrics Performance Monitor and the Everlast smartwatch. Methods We enrolled 127 patients (>18 years) from the Thomas Jefferson University Hospital Preadmission Testing Center. SBP and HR were measured by both investigational devices. In addition, the Everlast watch was utilized to measure DBP, and the BodiMetrics Performance Monitor was utilized to measure SpO2. After 5 min of quiet sitting, four hospital-grade standard and three investigational vital sign measurements were taken, with 60 seconds in between each measurement. The reference vital sign measurements were calculated by determining the average of the two standard measurements that bounded each investigational measurement. Using this method, we determined three comparison pairs for each investigational device in each subject. After excluding data from 42 individuals because of excessive variation in sequential standard measurements per prespecified dropping rules, data from 85 subjects were used for final analysis. Results Of 85 participants, 36 (42%) were women, and the mean age was 53 (SD 21) years. The accuracy guidelines were only met for the HR measurements in both devices. SBP measurements deviated 16.9 (SD 13.5) mm Hg and 5.3 (SD 4.7) mm Hg from the reference values for the Everlast and BodiMetrics devices, respectively. The mean absolute difference in DBP measurements for the Everlast smartwatch was 8.3 (SD 6.1) mm Hg. The mean absolute difference between BodiMetrics and reference SpO2 measurements was 3.02%. Conclusions Both devices we investigated met accuracy guidelines for HR measurements, but they failed to meet the predefined accuracy guidelines for other vital sign measurements. Continued sale of consumer physiological monitors without prior validation and approval procedures is a public health concern.

The Bengal monitor lizard or Common Indian monitor lizard (Varanus bengalensis Daudin, 1802) is classified as Least Concern under the IUCN and listed under the Schedule-I of the Indian Wildlife Protection Act 1972. Further, the trade of the species is prohibited as the species is listed in Appendix I of CITES. It is widely distributed over Western Asia, the Indian Subcontinent, and Southeast Asia (Koch et al. 2013). It is reported to occupy both terrestrial as well as freshwater habitats from desert areas to floodplains, scrubland to forests, in different types of terrains at elevations below 1500m (Auffenberg 1994; Papenfuss et al. 2010). Body size of individuals varies from 61 to 175 cm from the tip of the snout to the end of the tail (Auffenberg 1994; Losos and Greene, 1998). Adults are generally grey or greenish-grey in color, with a ventral pattern of grey to black crossbars from the chin to the tail. Adult individuals are less contrasting and have a less distinct pattern than younger individuals. The species shows a sexual dimorphism, with males being heavier (around 7.18 to 10 kg) than females which are about 40% smaller in size (Papenfuss et al. 2010).

IntroductionNew glucose-monitoring technologies have different cost–benefit profiles compared with traditional finger-prick tests, resulting in a preference-sensitive situation for patients. This study aimed to assess the relative value adults with diabetes assign to device attributes in two countries.Research design and methodsAdults with type 1 or 2 diabetes from the Netherlands (n=226) and Poland (n=261) completed an online discrete choice experiment. Respondents choose between hypothetical glucose monitors described using seven attributes: precision, effort to check, number of finger pricks required, risk of skin irritation, information provided, alarm function and out-of-pocket costs. Panel mixed logit models were used to determine attribute relative importance and to calculate expected uptake rates and willingness to pay (WTP).ResultsThe most important attribute for both countries was monthly out-of-pocket costs. Polish respondents were more likely than Dutch respondents to choose a glucose-monitoring device over a standard finger prick and had higher WTP for a device. Dutch respondents had higher WTP for device improvements in an effort to check and reduce the number of finger pricks a device requires.ConclusionCosts are the primary concern of patients in both countries when choosing a glucose monitor and would likely hamper real-world uptake. The costs-benefit profiles of such devices should be critically reviewed.

Full textAbstract:
The tiger mosquito was introduced to the Eastern region of the Mediterranean basin more than twenty years ago. In Lebanon, it was first observed in 2002 in a limited number of locations mainly from the coastal area of the country. In the absence of national entomological control program, this invasive mosquito became an established species and is now considered in many localities, a source of nuisance because of its human biting behavior. Several entomological surveys were conducted to monitor the geographic spread and the seasonal dynamics of Aedes albopictus by collecting adult stages and by monitoring oviposition activity. Moreover, its susceptibility to the common groups of insecticides was assessed using WHO standard bioassays. Previous vector competence studies revealed that local strains were able to transmit Chikungunya and Dengue viruses. Due to the increased risk of Zika virus introduction in the country, we determined the competence of local populations to transmit this virus. Mapping results showed that Ae. albopictus is mainly spread in the relatively humid western versant of the Mount Lebanon chain reaching 1000m altitude, while it is absent from arid and semi-arid inland areas. Besides, this mosquito is active during 32 weeks from spring till the end of autumn. Local strains of the tiger mosquito are susceptible to pyrethroids and carbamates but resistant to organophosphates and organochlorines. They showed ability to transmit Zika virus; however, only 9% of females were capable to excrete the virus in their saliva at day 28 post infection. Current and previous observations highlight the need to establish a surveillance system in order to control this mosquito and monitor the potential introduction of related diseases.

Fish has been regarded as a source of nutritious and highly desirable food. This is due to its high quality meat which is rich in essential amino acids, beneficial fatty acids, calcium, phosphorus and vitamins. However, the pollution of the aquatic environment with heavy metals has become a serious health concern for fish and human populations. Industrial and agricultural discharges are considered as the primary source of metal poisoning of fish (Pandey, 2003). The aim of this study was to assess the bioaccumulation of trace metals in samples of skin, scales, gills and fins of fish to monitor freshwater pollutions. This information may help adopt practices to avoid the impacts of these pollutants on the aquatic and human populations.

Controlling information and keeping an eye on enemies were two fun-damental activities for the different revolutionary factions in the revolu-tionary decade (1910-1920) and in the early years of the post-revolutionary stage. The armed struggle has aspects that have been little explored and that reflected the concern to watch over and censure its en-emies. Francisco I. Madero failed in his attempts to neutralize the op-position forces; Venustiano Carranza, on his part, managed to monopo-lize information and build the foundations of intelligence networks that would make it possible for the Carrancistas to stop possible uprisings. The assassination of Carranza in May 1920, far from ending these prac-tices, led the new group in power ― headed by Generals Álvaro Obregón and Plutarco Elías Calles, as well as Adolfo de la Huerta ― to improve their confidential intelligence services and closely monitor the opposition press.

Abstract Since tragedies caused by nuclear disasters are always a concern, it is essential that nuclear power plants be monitored on a regular basis for any irregularities in ionising radiation levels. Irrespective of leakage proof measures being deployed in the plant, ensuring the safety of these measures is necessary. Given this scenario, the present study proposes the usage of unmanned aerial vehicles (UAVs) to ensure that radiation levels in nuclear plants remain within safe limits. The UAV deployed will map the entire environment following a unique path planning algorithm and monitor the environment with an onboard radiation sensor. If any irregularities are detected, the positional coordinates are flagged, and the A* algorithm is implemented to generate the shortest path between the starting point, and the flagged coordinates, which are considered as the destination coordinates. The UAV is made to traverse the shortest path together with maintaining stability of the system while traversing.

Nowadays, automation in the baby cradle system proved reliable and supports in effective baby monitoring. This system monitors the baby's mattresses condition, cry detection, body temperature etc., and thus provides better care for the babies. Also it makes the parents very easy to take care of the baby and experience those worry-free feelings. Especially for the professional women who are busy in their work schedules, always find scarcity of time to take care of the baby. As a concern of money, they are unable to afford a maid or nursery to look after their baby. In this paper, a local market is studied to decide the degree of automation and best suit mobile application required for the smart baby cradle. Three sensors are used such as a sound sensor for detecting the crying sound of a baby, a wet sensor for detecting the condition of mattresses, and a temperature sensor for detecting the body temperature. To make this automated cradle internet of things (IoT) based, a Blynk platform is used and this entire feature is monitored and controlled via mobile phone. An automatic swing motion of the cradle is provided using a link mechanism. Automation in the cradle allows the remote parent to take care of their baby, monitor its actions, and maintain the balance in their professional and personal lives.

The low level of trust in online exam results from students is a major problem because it is difficult to monitor whether test takers are taking the exam honestly according to their own abilities. Even though it has been assisted by the presence of video conferencing applications such as Zoom, Google Meet, Cisco Webex and similar applications, online exam proctoring is still unable to run effectively. Cheating in online exams, such as using dual monitors, is very possible for exam participants. Therefore, as a future preventive measure in the online exam process, a system is needed that can accommodate this concern. This research will create an online exam supervision system with WebRTC technology which has features to accommodate real-time supervision. The System Development Life Cycle method will be used in software development with 5 main stages, namely Requirement Analysis, Design, Development, Testing, and Maintenance. Implementation of the system was carried out during the online examination process for a class at one of the universities in Surabaya. Finally, the test results show that features such as: Live Proctoring get a score of 4.5; Attention Alert gets a score of 5; Exam Lock scored 4.5; Live Alert scored 4.5; and Tab & Window Detection got a score of 4; shows that this system has succeeded in providing a solution in online exam proctoring needs.

As the world grapples with the pressing challenge of environmental sustainability, the need for innovative solutions to combat air pollution has become paramount. Air pollution is a complex issue that necessitates real-time monitoring of pollution sources for effective mitigation. This paper explores the potential of swarm algorithms applied as a novel and efficient approach to address this critical environmental concern. Swarm algorithms offer a promising framework for coordinating fleets of drones to collaboratively monitor and analyze air pollution sources. The unique capabilities of drones, including their agility, accessibility, and versatility, make them ideal candidates for aerial data collection. When harnessed in a swarm, these drones can create a dynamic and adaptable network that provides a more comprehensive and fine-grained understanding of air pollution dynamics. This paper delves into the conceptual foundations of using swarm algorithms in drone-based air pollution monitoring.

Concorde was decommissioned in 2003, ending civil supersonic aircraft operations in the world. However, today there is continued interest by proponents/developers of supersonic aircraft that believe by utilizing advanced technologies, new supersonic aircraft can be economically viable, safe, reliable, and significantly quieter than the Concorde. In 2004, the International Civil Aviation Organization (ICAO)’s formed a Supersonic (noise) Task Group to monitor whether supersonic research and developments could revive lost high-speed capabilities and support commercially viable, environmentally responsible global aviation operations. Since then, the United States has been focused on progressing work related to the need for a landing and takeoff noise standard for supersonic aircraft, and an en-route sonic boom standard. This presentation briefly highlights achievements to date that intend on opening the new era of supersonic flight ahead.

During the COVID-19 pandemic, people around the world have been affected by strict restrictions on movement and social isolation, thus limiting access to physical activity. The objective of this study was to analyze the variations in the level of physical activity related to the time of physical exercise, number of steps and time standing in Apple Watch users. Regardless of gender, a significant reduction in the number of steps during the period of social isolation was observed in eutrophic and overweight subjects. An increase in the percentage of Exercise Days (%/mo) was observed only in the obese in June. In overweight subjects of both genders, they were the ones who presented a greater physical exercise levels per day and per week. The main reduction in Stand (hr/day) occurred in eutrophic men, and the greatest increase in obese women. Based on the results, we conclude that in the same way that the implementation of restrictive measures of social isolation initially provided an increase in sedentary behavior and a reduction in the practice of exercises, with the extension of these measures, new opportunities and alternatives emerged for changing behavior related to physical activity due to the increase in free time and greater concern with health care.

AbstractThis article explores the events surrounding the Monitor controversy, which stemmed from radical criticism of the crown's conservative approach to the war between Spain and Great Britain in 1762. While some observers wished to quickly bring the war to an end, others expressed more radical plans for the destruction of the Spanish Empire. When the crown retaliated against prominent agitators with a round of arrests designed to silence their dissent, the result was a succession of legal cases that culminated with Entick v. Carrington in 1765. In their arguments, the plaintiffs expressed concern that the British Empire was seemingly in danger of evolving into an oppressive, allegedly “Spanish” style of polity. These legal processes and the precedents they set were critical to the development of protected space for political dissent in the British Empire, and affirmed a more broadly participatory model for the future development of imperial policy.

Those with no history of elevated readings had limited concern over their BP: self-screening filled the time waiting for their appointment or was done to help their doctor. Patients with hypertension self-screened to avoid the feelings they associated with ‘white coat syndrome’ and to introduce more control into the measurement process. Barriers to self-screening included a lack of awareness, uncertainty about technique, and worries over measuring BP in a public place. An unanticipated finding was that several interviewees preferred monitoring their BP in the waiting room than at home.ConclusionBP self-screening appeared acceptable to service users. Further promotion and education could increase awareness among non-users of the need for BP screening, the existence of self-screening facilities, and its ease of use. Waiting room monitors could provide an alternative for patients with hypertension who are unwilling or unable to monitor at home.

Background: Adverse drug reactions (ADRs) are an important concern in modern therapeutics. Due to limitations in identifying ADRs during research phase, organized post marketing studies are essential. However, there are only few recent studies on this subject available in India. Hence this study was done in a tertiary care hospital in South Kerala to evaluate the profile and causality of ADRs.Methods: The details of patients who developed ADRs during the period from October 2016 to November 2017 were collected. Data collection was done using the suspected drug reactions monitoring form by CDSCO used under PvPI and a retrospective observational cross-sectional analysis was done. The profile and causality of ADRs were evaluated.Results: The total number of ADR events reported was 300. 179 ADRs were hypersensitivity reactions (Aronson Type B) and the remaining 121 reactions were Type A reactions. The individual drug class causing majority of the ADRs was antibiotics (36%). Commonest significant dose related ADR was bleeding (7%) caused by combined use of antiplatelets and anticoagulants. The organ system most affected as per SOC classification was skin and appendages (56%). Causality assessment revealed that majority (76%) belonged to “probable” category, whereas 23.6% were of “possible” type.Conclusions: The development of ADRs can significantly affect treatment course – interruption of drug therapy, use of additional drugs and prolonged hospital stay. Employing monitors dedicated to ADR detection and education of prescribers to closely monitor patients can help manage ADRs effectively.

Contamination of waterways is of increasing concern, with recent studies demonstrating elevated levels of antibiotics, antidepressants, household, agricultural and industrial chemicals in freshwater systems. Thus, there is a growing demand for methods to rapidly and conveniently monitor contaminants in waterways. Here we demonstrate how a combination of paper microfluidic devices and handheld mobile technology can be used by citizen scientists to carry out a sustained water monitoring campaign. We have developed a paper-based analytical device and a 3 minute sampling workflow that requires no more than a container, a test device and a smartphone app. The contaminant measured in these pilots are phosphates, detectable down to 3 mg L-1. Together these allow volunteers to successfully carry out cost-effective, high frequency, phosphate monitoring over an extended geographies and periods.

Abstract: Animal-induced crop damage in India is a major concern, causing reduced agricultural output. Conventional farming methods are insufficient, and guards are impractical. To address this, a machine learning project is proposed, utilizing deep neural networks to detect animals entering farms. The project uses cameras to monitor the farm, identifying instances of animal intrusion and using sound cues to deter them.

Air pollution is one of the biggest problems affecting large urban areas. Better monitoring of regions suffering from this type of pollution is in the interest of public health. Although many cities employ sensors to monitor air pollution, a current concern is how to establish the ideal number of sensors to monitor a given geographical region. To address this concern, this research proposes a method to optimize the number of sensors in an air pollution monitoring network to cover a given region efficiently and precisely and uses the metropolitan region of São Paulo, Brazil, and CO sensors as an example. The model of Fragmentation into Groups via Routes is proposed to distribute sensors within micro-regions that display similar air pollution characteristics. A network of virtual sensors is created, and the output of each sensor is established using a method of spatial interpolation called IDW. To identify the optimum sensor configuration, a genetic algorithm is used to assess the topology with the lowest variance of data spread. A lesser number of sensor stations to be treated leads to faster responses to sudden changes in urban conditions. Therefore, municipality authorities can take quick measures to improve the population’s wellness.

AbstractBackgroundPsychiatric prescribers typically assess adherence by patient or caregiver self-report. A new digital medicine (DM) technology provides objective data on adherence by using an ingestible event monitoring (IEM) sensor embedded within oral medication to track ingestion. Despite likely clinical benefit, adoption by prescribers will in part depend on attitudes toward and experience with digital health technology, learning style preference (LSP), and how the technology s utility and value are described.Objectiveis to identify attitudes, experiences, and proclivities toward DM platforms that may affect adoption of the IEM platform and provide direction on tailoring educational materials to maximize adoption. Methods A survey of prescribers treating seriously mentally ill patients was conducted to assess drivers/barriers to IEM adoption. Factor analysis was performed on 13 items representing prior experience with and attitudes toward DM. Factor scores were correlated with prescriber characteristics including attitude and experience with digital technologies, LSP, and level of focus on healthcare cost.ResultsA total of 127 prescribers (56% female, 76% physicians, mean age 48.1yrs.) completed the survey. Over 90% agreed medication adherence is important, visits allow enough time to monitor adherence (84.1%), and tailoring treatment to level of adherence would be beneficial (92.9%). The majority (65.9%) preferred relying upon outcomes data as their learning style while 15.9% preferred opinion leader recommendations and 18.3% information about how the technology would affect practice efficiency. Factor analysis revealed four dimensions: Level of comfort with EHR; Concern over current ability to monitor medication adherence; Attitudes about value of DM applications; and Benefits vs cost of DM for payers. Women scored higher on attitudes about the value of digital applications (p<0.01). Providers who perceive non-adherence as costly, and those who believe DM could benefit providers and patients scored higher on the value of DM (p<.05). Those whose LSP focuses on improving efficiency and prescribers with a higher proportion of Medicaid/ uninsured patients displayed concern about their ability to monitor adherence (p<0.05). Willingness to be a Beta Test site for DM applications was positively correlated with concern about their ability to monitor adherence and attitudes about the value of DM (p <0.01).ConclusionsPrescriber characteristics including LSP, focus on healthcare costs, and attitudes toward DM may be related to adoption of the IEM platform. Those with more Medicaid/ uninsured patients were more concerned about ability to monitor adherence while those focused-on cost and benefit to providers and patients viewed DM as part of a solution for managing outcomes and cost. Overall, LSP, patient panel size by payer type, and focus on healthcare cost containment should be considered when developing IEM provider training materials.FundingOtsuka Pharmaceutical Development & Commercialization, Inc.
