Detection of upwelling events in the Caspian Sea using thermal satellite image processing

In this article, we studied the upwelling phenomena observed in the surface waters of the Caspian Sea. Studying upwelling is crucial for understanding and managing the complex interactions between the ocean, climate, and marine life, with implications for both environmental conservation and human well-being. To accomplish this, we utilized data from MODIS-Aqua satellite observations in the infrared range of 11 microns. These observations had a spatial resolution of 4 km and covered the period from 2003 to 2021. The data was accessed through the NASA Giovanni online data system databases. Our findings indicate that upwelling phenomena are primarily observed in the eastern part of the Middle and South Caspian from May to September. The most intense upwelling occurs along the eastern coast of the Middle Caspian in July and August. Based on long-term averaged data, the upwelling phenomenon is typically observed between 40-44º latitude during this period. The width of the upwelling zone increases gradually from north to south, extending approximately 60-70 km towards the Kazakh Gulf before decreasing towards the south. In the upwelling zone, the temperature gradient can at times reach 4.0ºC per 100 km. In certain years, the upwelling zone that initially forms along the eastern coasts can extend over long distances and even reach the western coasts. Generally, the upwelling phenomenon occurs alongside the advection of warm waters from the South Caspian towards the Middle Caspian.

Introducing Elinor for monitoring the governance and management of area-based conservation.

Monitoring the governance and management effectiveness of area-based conservation has long been recognized as an important foundation for achieving national and global biodiversity goals and enabling adaptive management. However, there are still many barriers that prevent conservation actors, including those affected by governance and management systems from implementing conservation activities and programs and from gathering and using data on governance and management to inform decision-making across spatial scales and through time. We explored current and past efforts to assess governance and management effectiveness and barriers actors face in using the resulting data and insights to inform conservation decision-making. To help overcome these barriers, we developed Elinor, a free and open-source monitoring tool that builds on the work of Nobel Prize winner Elinor Ostrom to facilitate the gathering, storing, sharing, analyzing, and use of data on environmental governance and management across spatial scales and for areas under different governance and management types. We consider the process of codesigning and piloting Elinor with conservation scientists and practitioners and the main components of the assessment and online data system. We also consider how Elinor complements existing approaches by addressing governance and management in a single assessment at a high level for different types of area-based conservation, providing flexible options for data collection, and integrating a data system with an assessment that can support data use and sharing across different spatial scales, including global monitoring of the Global Biodiversity Framework. Although challenges will continue, the process of developing Elinor and the tool itself offer tangible solutions to barriers that prevent the systematic collection and use of governance and management data. With broader uptake, Elinor can play a valuable role in enabling more effective, inclusive, and durable area-based conservation.

Disparities in Rates of Death From HIV or Tuberculosis Before Age 65 Years, by Race, Ethnicity, and Sex, United States, 2011-2020.

Death from tuberculosis or HIV among people from racial and ethnic minority groups who are aged <65 years is a public health concern. We describe age-adjusted, absolute, and relative death rates from HIV or tuberculosis from 2011 through 2020 by sex, race, and ethnicity among US residents. We used mortality data from the Centers for Disease Control and Prevention online data system on deaths from multiple causes from 2011 through 2020 to calculate age-adjusted death rates and absolute and relative disparities in rates of death by sex, race, and ethnicity. We calculated corresponding 95% CIs for all rates and determined significance at P < .05 by using z tests. For tuberculosis, when compared with non-Hispanic White residents, non-Hispanic American Indian or Alaska Native residents had the highest level of disparity in rate of death (666.7%). Similarly, as compared with non-Hispanic White female residents, American Indian or Alaska Native female residents had a high relative disparity in death from tuberculosis (620.0%). For HIV, the age-adjusted death rate was more than 8 times higher among non-Hispanic Black residents than among non-Hispanic White residents, and the relative disparity was 735.1%. When compared with non-Hispanic White female residents, Black female residents had a high relative disparity in death from HIV (1529.2%). Large disparities in rates of death from tuberculosis or HIV among US residents aged <65 years based on sex, race, and ethnicity indicate an ongoing unmet need for effective interventions. Intervention strategies are needed to address disparities in rates of death and infection among racial and ethnic minority populations.

First Report on the Reproductive Biology of the Redtail Scad Decapterus kurroides Bleeker, 1855 in Iligan Bay, Southern Philippines

This study provided the first report on the reproductive biology of the redtail scad, Decapterus kurroides. The reproductive activity of the redtail scad was assessed to characterize its sex ratio, spawning period, length at maturity, and fecundity. Meanwhile, remote sensing data on environmental variables were accessed from Giovanni online data system. Fish samples were collected monthly from October 2017 to September 2018 from both commercial and municipal landed catches. Male D. kurroides was found to have a larger size than the female in terms of mean total length and mean body weight, but it did not differ significantly from the female (t = 1.31, df = 1,348, p = 0.19). Collected male and female samples were mostly in the 15.1 – 18.0 cm size class. Overall sex ratio exhibited female dominance (1.2:1), which significantly deviated from the 1:1 ratio (x2 = 8.17, p = &lt;0.05). As expected for tropical fish, spawning of D. kurroides occurred year-round, with peak spawning in December and minor spawning events in March and August, as reflected in the monthly percent occurrence of different gonad maturity stages and gonadosomatic index evolution. Among the environmental variables evaluated, sea surface temperature appeared to have more influence on the spawning of D. kurroides followed by chlorophyll-a concentration. Females matured at a length of 17.2 cm, while males matured at a length of 17.6 cm. Absolute fecundity ranged from 6,416 to 197,672 eggs per female with a mean of 61,733 ± 3,955 and increased proportionally with gonad weight. Information from this study may be used to formulate effective management strategies for the resource.

Comparison of the gastric biopsy results of Afghan refugees and Turkish people

Helicobacter pylori- (H. pylori) infection is one of the effective factors in the development of gastric premalignant lesions, and it is known that socioeconomic conditions are closely related to H. pylori infection. Our aim was to show whether there were differences regarding H. pylori infection and gastric histopathological findings between humans who had to manage an exhausting escape out of their own country and residents of a coastal town in the black sea region of Turkey. Endoscopic findings of Turkish and Afghan patients who underwent gastroscopy for various reasons, gastric biopsies, and their histopathological results (H. pylori, intestinal metaplasia, and gastric atrophy) and some biochemical parameters were retrospectively screened from the hospital online data system. A total of 222 patients, 41 Afghan and 181 Turkish, were included in the study. There were no significant differences regarding age and gender of the patients between the groups. The percentage of the patients with intestinal metaplasia and H. pylori infection was higher in the group of the Afghan patients than in Turkish patients. Afghan refugees had similar rates of atrophic gastritis (23.1% versus 21.5%; p=0.834), when compared to resident controls. Risk factors of gastric cancer include the presence of H. pylori infection, atrophic gastritis, and intestinal metaplasia. This study supports the knowledge that socioeconomic factors such as low economic conditions and poor health infrastructure are one of the major causes of widespread global H. pylori infection status.

Comparison of bypass versus primary angioplasty for lower extremity chronic limb-threatening peripheral arterial diseases

Aim: Peripheral arterial Diseases (PAD) is seen frequently with increasing age, and have a prevalence of about 20% over 70 years of age. We aimed the results of two different treatment approaches as open surgical procedures and radiological interventions. &#x0D; Methods: We reviewed the data of PAD from the online data system of the hospital. The patients treated by endovascular femoropopliteal revascularization versus open surgical femoropopliteal graft bypass between January 2016 and December 2019 were enrolled in to study. Eighty limbs of 67 patients with the symptomatic severe occlusive disease and results were evaluated in the aspect of reducing ischemia and prevention of amputation in this retrospective study.&#x0D; Results: 67 patients were divided into two groups. Group 1(n=29) was the interventional PTA/S group, group 2 (n=38) was the open surgical bypass group. 8 of the patients in Group 2 and 5 of patients in Group 1 had bilateral lesions. Patients were at a mean age of 63.44±8.98 years. The mean time of hospitalization time was significantly longer following a first-time bypass (10 vs. 8 days). The success of results was ending of claudication and ischemia and prevention of amputation of an extremity. In these aspects, there was no difference between procedure types. &#x0D; Conclusion: In the aspect of the length of hospital stay and infection, interventional procedures seem more benefit however in long-term evaluation, freedom from reintervention or redo bypass was significantly higher in the bypass group (92% vs 79 % p

Rethinking teacher evaluation using human, social, and material capital

Teacher evaluation’s relationship with instructional improvement is under-theorized in the literature. To address this gap, this paper uses a conceptual framework rooted in human, social, and material capital to analyze and synthesize findings from research conducted since 2009 on whether and under what conditions teacher evaluation stimulates change in teachers’ instruction. We find that teacher evaluation can facilitate instructional improvement if evaluators understand teaching and the teacher evaluation system and teachers and evaluators trust each other and have opportunities to develop social capital regarding instruction. In addition, adequate time and a userfriendly online data system appear to facilitate the use of teacher evaluation to stimulate changes in teachers’ practice. This paper thus presents a theoretical framework, rooted in theory and empirical research, that may prove useful to scholars and practitioners.

ONSTAGE, the Online Data System of Theatre in Amsterdam from the Golden Age to Today

Abstract ONSTAGE is the data repository for Amsterdam’s first and most prominent public theatre venue: the Schouwburg. In theatre history, the Amsterdam Schouwburg has a fairly unique place due to its rich body of extant account books, programs and administrative records of annual play lists, and registers of expenses and revenues. These sources, as a most sensitive finger on the theatre’s pulse, can be used as analytical tools that provide access to the theatre’s artistic business, from its foundation in 1638 until today. This data paper is an assessment of the new ONSTAGE data system, in terms of its structure, the nature of the data and enrichment, and the research potential. The paper also explores future growth in linked data systems.

Data integration through brain atlasing: Human Brain Project tools and strategies

The Human Brain Project (HBP), an EU Flagship Initiative, is currently building an infrastructure that will allow integration of large amounts of heterogeneous neuroscience data. The ultimate goal of the project is to develop a unified multi-level understanding of the brain and its diseases, and beyond this to emulate the computational capabilities of the brain. Reference atlases of the brain are one of the key components in this infrastructure. Based on a new generation of three-dimensional (3D) reference atlases, new solutions for analyzing and integrating brain data are being developed. HBP will build services for spatial query and analysis of brain data comparable to current online services for geospatial data. The services will provide interactive access to a wide range of data types that have information about anatomical location tied to them. The 3D volumetric nature of the brain, however, introduces a new level of complexity that requires a range of tools for making use of and interacting with the atlases. With such new tools, neuroscience research groups will be able to connect their data to atlas space, share their data through online data systems, and search and find other relevant data through the same systems. This new approach partly replaces earlier attempts to organize research data based only on a set of semantic terminologies describing the brain and its subdivisions.

Predicting water allocation trade prices using a hybrid Artificial Neural Network-Bayesian modelling approach

This paper proposes an integrated (hybrid) Artificial Neural Network-Bayesian (ANN-B) modelling approach to improve the accuracy of predicting seasonal water allocation prices in Australia’s Murry Irrigation Area, which is part of one of the world’s largest interconnected water markets. Three models (basic, intermediate and full), accommodating different levels of data availability, were considered. Data were analyzed using both ANN and hybrid ANN-B approaches. Using the ANN-B modelling approach, which can simulate complex and non-linear processes, water allocation prices were predicted with a high degree of accuracy (RBASIC = 0.93, RINTER. = 0.96 and RFULL = 0.99); this was a higher level of accuracy than realized using ANN. This approach can potentially be integrated with online data systems to predict water allocation prices, enable better water allocation trade decisions, and improve the productivity and profitability of irrigated agriculture.

International burden of chronic kidney disease and secondary hyperparathyroidism: a systematic review of the literature and available data.

The international burden of secondary hyperparathyroidism (SHPT) is unknown, but it may be estimable through the available chronic kidney disease and SHPT literature. Structured reviews of biomedical literature and online data systems were performed for selected countries to ascertain recent estimates of the incidence, prevalence, and survival of individuals with CKD and SHPT. International societies of nephrology were contacted to seek additional information regarding available data. Estimates were abstracted from 35 sources reporting estimates of CKD in 25 countries. Population prevalence estimates of CKD stages 3–5 in adults ranged from approximately 1 to 9% (China, Mexico, resp.). Estimates of the population prevalence of maintenance dialysis therapy ranged from 79 per million population (pmp; China) to 2385 pmp (Japan); incidence rates ranged from 91 pmp (United Kingdom) to 349 pmp (United States). Prevalence of SHPT among stage 5D populations was highly variable and dependent upon the disease definition used. Among the few nations reporting, approximately 30–50% of stage 5D patients had serum parathyroid hormone levels >300 pg/mL. Reported incidence and prevalence estimates across the individual nations were variable, likely reflecting differing population demographics, risk factors, etiologies, and availability of treatment through all stages of CKD.

METHODS Patients reporting to the kidney stone clinic were interviewed to collect information on stone history (procedures, stone passage, pain, dietary and medical treatments) and demographic information (age, gender, whether primary income earner or caregiver, and presence of other chronic illnesses), and were asked to complete the PROMIS-43 questionnaire. The PROMIS-43 is an NIH-sponsored online data system that utilizes validated questionnaires for each domain. Results were analyzed using gender and age matched groups for the general US population. Scores are reported as a percent. The general population mean is set at 50% with a standard deviation of 10%. RESULTS 100 patients completed the survey. 36% of respondents were male, the average age of the group was 52 ± 13.2 years old, with 58% primary income earners, and 35% primary caregivers for children. 38% had never passed a stone while 17% passed 10 or more stones in their lifetime. 67% of patients had at least one ureteral stent, and 87% had at least one stone removal procedure. Overall, 45% had shockwave lithotripsy, 51% ureteroscopy, and 30% percutaneous nephrolithotomy, with an average of 2.4 procedures per subject. Urolithiasis patients had greater pain interference (53%, p<0.001), lower physical function (47%, P<0.005), and lower depression (47.5%, p<0.005) than matched controls. No differences existed in anxiety, fatigue, or sleep disturbance. Patients who had passed 10 or more stones in a lifetime had significantly worse pain interference and depression (Figure 1). CONCLUSIONS Urolithiasis patients subjectively have worse pain and physical function than the general population, however they have less depression. The impact of pain on quality of life was greatest in those patients who had passed more than 10 stones in their lifetime; underscoring the importance of preventive measures. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e210-e211 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Robert Brown More articles by this author Carl Sarkissian More articles by this author Manoj Monga More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...

Totale extraperitoneale Hernioplastik

Minimally invasive repair with alloplastic material for inguinal hernia has become a method with few complications and a low recurrence rate. Persistent pain and dysesthesia years after the procedure are however of growing clinical interest. It is still unknown to what degree initial pain or dysesthesia change in the long term. Therefore this study was done to evaluate patient complaints following total extraperitoneal repair (TER) over a long observation period.Included in the study were patients from January 2000 to December 2006 who were treated electively for uni- or bilateral inguinal hernia using TER. Exclusion criteria were emergency procedures, incarcerated hernia, and scrotal hernia. The patient data were collected using a prospective online data system and evaluation of long-term results via standardized questionnaires determining persisting pain, dysesthesia, physical limitations from the surgery, satisfaction with the operation, and recurrences. The patients were grouped according to length of follow-up after surgery: 12-36 months (group 1), 37-60 months (group 2), and 61-96 months (group 3).Since January 2000, 484 patients 18 to 97 years old with 620 inguinal hernias were operated. Of those, 349 were evaluated for this study (proportion of returned questionnaires: 72.1%). No significant differences were noted in patient characteristics or early postoperative complications. The percentage of patients suffering from relevant pain (moderate to severe) dropped significantly: 10.3% (group 1) vs 1.0% (group 2) (P<0.05) and 3.4% (group 3) (P<0.05). No significant differences were found concerning dysesthesia (19.6% in group 1 vs 19.2% in group 3). There were no significant differences in satisfaction with the operation, as 73.8% in group 1, 67.7% in group 2, and 73.3% in group 3 were very satisfied with the results. The number of recurrences increased during the observation period: 1.9% in group 1, 3.1% in group 2, and 5.5% in group 3 (P>0.05).Total extraperitoneal repair is a reliable method with low recurrence rate and high patient satisfaction. A relevant proportion of patients complain however of pain and dysesthesia persisting over years. The data from this study show that in the long term, pain incidence drops significantly while the rate of dysesthesia remains constant. Long follow-up is needed to evaluate the long-term course of persistent pain. For more precise understanding of the long-term results of herniotomy, prospective randomized studies are needed with accordingly long follow-up.

Data Acquisition for a 16 CCD Drift‐Scan Survey

ABSTRACTThe QUEST (QUasar Equatorial Survey Team) collaboration is using an innovative 16 CCD mosaic camera at the prime focus of the 1 m Venezuelan Schmidt telescope to conduct a drift‐scan survey of the equatorial sky (≈4000 deg2 with |b|>25). The data products, which consist of UBV photometry to mB ≈ 21 and objective prism spectroscopy to mB ≈ 19, will have various applications in addition to producing a homogenous sample of ∼104 quasars. In this paper we describe the online data system, which is responsible for controlling the camera, and acquiring and managing ≈30 GB of raw image data per night. The data system, designed to be highly scalable and cost effective (under $10,000), distributes the data I/O and processing in parallel across a cluster of commodity PC components. We currently use seven Pentium‐class processors (75–133 MHz), interconnected with parallel Ethernet networks, running the QNX real‐time, network‐wide operating system. To ease the data handling, fast algorithms provide various levels of online analysis and data compression, including a new lossless compression scheme based on adaptive linear prediction.

Online access to weather satellite imagery through the World Wide Web

Both global area coverage (GAC) and high-resolution picture transmission (HRPT) data from the Advanced Very High Resolution Radiometer (AVHRR) are made available to Internet users through an online data access system. Older GOES-7 data are also available. Created as a data system for NASA's future Earth Observing System Data and Information System (EOSDIS), this testbed provides an opportunity to test both the technical requirements of an online data system and the different ways in which the general user community would employ such a system. Initiated in December 1991, the basic data system experienced five major evolutionary changes in response to user requests and requirements. Features added with these changes were the addition of online browse, user subsetting, dynamic image processing/navigation, a stand-alone data storage system, and movement from an X-windows graphical user interface (GUI) to a World Wide Web (WWW) interface. Over its lifetime, the system has had as many as 2500 registered users. The system on the WWW has had over 2500 hits since October 1995. Many of these hits are by casual users that only take the GIF images directly from the interface screens and do not specifically order digital data. Still, there is a consistent stream of users ordering the navigated image data and related products (maps and so forth). The authors have recently added a real-time, seven-day, northwestern United States normalized difference vegetation index (NDVI) composite that has generated considerable interest.

Supervisory adaptive control for the structural vibration of a coordinate-measuring machine

A supervisory adaptive control approach has been developed for a structural vibration control of a coordinate measuring machine, which is a dynamic system with time varying system model order and parameters. An on-line dynamic data system modelling algorithm is used to identify the system model order and parameters simultaneously. Based on the identified model, a predictive control algorithm is applied to generate control commands. A supervisory strategy with several monitoring indices and decision-making rules is proposed to supervise the modelling and control processes. The developed supervisory adaptive control approach has been implemented in a digital signal processor board for structural vibration control. Experimental results indicate a 75% reduction in the peak-to-peak vibration and an 80% reduction in the settling time.

Real-time monitoring of atmospheric aerosols using a computer-controlled lidar

Regular monitoring of aerosol parameters during nighttime in the tropical urban lower atmosphere using a tunable, continuous wave, bistatic argon ion laser radar (lidar) system was initiated at the Indian Institute of Tropical Meteorology, Pune (18°32′N, 73°N51′E), India in 1986. So far, the measurements have been made from manual operation of the lidar which consumes a lot of time and inhibits interpretation of results immediately after completion of the experiment. In order to improve and expedite the data acquisition-processing and to avoid extra manual work to a considerable extent, the lidar has recently been made fully automatic. This paper discusses the on-line control and digital data system that provides real-time acquisition, analysis and display of lidar data. The improvements in the data quality and application of the system to the real-time observation of various features connected with atmospheric aerosol variations in both space and time are presented. The previously used lidar data acquisition and handling techniques and those of the present auto-mode operation are compared. Such real-time aerosol observations on a long-term basis are expected to lead to a better understanding of the optical properties of aerosols and their interaction with clouds and climate and will hopefully add to the global monitoring efforts and attempts at incorporating aerosols into climate models.
