Marine Heatwaves

Ocean temperature variability is a fundamental component of the Earth's climate system, and extremes in this variability affect the health of marine ecosystems around the world. The study of marine heatwaves has emerged as a rapidly growing field of research, given notable extreme warm-water events that have occurred against a background trend of global ocean warming. This review summarizes the latest physical and statistical understanding of marine heatwaves based on how they are identified, defined, characterized, and monitored through remotely sensed and in situ data sets. We describe the physical mechanisms that cause marine heatwaves, along with their global distribution, variability, and trends. Finally, we discuss current issues in this developing research area, including considerations related to thechoice of climatological baseline periods in defining extremes and how to communicate findings in the context of societal needs.

A Five-Year Trend Analysis of Malaria Surveillance Data in Selected Zones of Amhara Region, Northwest Ethiopia

Background : Trend analysis of malaria surveillance data is essential to inform stakeholders on progress towards malaria control. From the total 387,096 cases of malaria reported in Amhara region in 2017, 167,079 (43.2%) cases were in Central, North and West Gondar zones. From this total figure of zones, 15,445 (9.2%) were ≤5 years which contributes 4 % of cases in the region. So, the purpose of this study was to analyze trends of malaria parasite in Selected Zones of Amhara Region, Northwest Ethiopia Methods : A Retrospective study was conducted in Central, North and West Gondar zones from July 1- 30/ 2018. Data were collected, entered, cleaned, analyzed and interpreted using Microsoft Excel-2010. Different tables, figures and maps were used to present results. Result : A total of 2,827,722 cases have been received a diagnostic test of; Microscopy 1,712,193(60.56%) and Rapid Diagnostic Test (RDT) 1,115,529(39.44%). Trends of total patients treated as confirmed and clinical malaria cases in July 2017- June 2018 were decreased to 139297 (14%) as compared from July 2015- June 2016, 249571(25%). From total cases received diagnostic tests only 1,003,391 (36%) were confirmed and clinical cases treated with antimalaria. Of these Plasmodium falciparum and vivax malaria cases were confirmed to be 1,002,946 (99.96%) and clinical malaria cases were 445(0.04%), respectively. Conclusion : Risk of infection and diagnostic effort were high in West Gondar Zone. The Amhara public health institute including health Bureau, stakeholders and all responsible bodies should give special standing to highest malaria districts of West Gondar zone.

Target-oriented data conditioning for prestack inversion in an unconventional reservoir: A Canadian case study

Target-oriented data conditioning is a key part of any reservoir characterization workflow. Data conditioning is used to optimize the match between the synthetic data, used in the prestack inversion, and the real data. When this is done correctly, the accuracy and confidence of inversion results may be greatly improved. This is proved on prestack seismic inversion results from a resource play in Canada. The flow is broken down into prestack gather conditioning, which improves the signal-to-noise and gather flatness, and poststack conditioning, which further improves the coherency prior to applying spectral balancing. As a final key step, spatially variant amplitude balancing is used to calibrate the angle stacks to the expected background trend from the well synthetics. The combination of all steps is demonstrated via [Formula: see text] and mu-rho versus lambda-rho crossplots, between the inverted results and the well measurements, to provide a significant improvement on the resolution and accuracy of the final prestack inversion.

Pola makan, obesitas, dan frekuensi serangan pada pasien artritis gout

Background: Trend of gout arthritis prevalence is increasing every year. Obesity, high purine diet, especially from an animal source, are some risk factors for recurrent gout attacks.Objective: To evaluate the relationship between diet, obesity, and frequency of gout flares in gout arthritis patients.Method: This study was a cross-sectional study with patients from RSUP Dr. Sardjito, RSUD Wirosaban, RSUD Panembahan Senopati that ever diagnosed as gout arthritis within February 2010 - February 2012 which can be seen in the medical record and live in Special District of Yogyakarta with the full address provided, as the respondents of this study. The home visit was done for dietary assessment, waist circumference measurement, and interviewing the respondent about gout flares frequency during the last year.Results: Vitamin C consumption in the 1st and 2nd tertiles increase the odds to have any gout flare (OR=5.5; 95% CI: 1.08-27.77 and OR=1.5; 95% CI: 0.29-7.35, respectively). Obesity tends to increase the odds of having any gout flares up to 1.4 times (95% CI: 0,38-5,25).Conclusion: Low consumption of vitamin C significantly increases the odds of having any gout flares. The odds is also higher in patients with obesity, though this relationship is statistically insignificant.

AVO polarization and hodograms: AVO strength and polarization product

An alternative approach to identifying amplitude‐variation‐with offset (AVO) anomalies is to consider the AVO polarization in the AVO intercept–AVO gradient (A‐B) plane. This method does not require deviations or separations from a background trend exhibited in traditional crossplots such as intercept‐gradient (A‐B) or near trace–far trace (N‐F). A benefit of the hodogram or polarization method is that the wavelet is taken into consideration. Crossplotted intercept and gradient are polarized along a “background trend” for nonanomalous events and at angles different from the “background trend” for anomalous events. This allows recognition of anomalous behavior otherwise buried in a background. Attributes resulting from this methodology include (1) the polarization angle, (2) the polarization angle difference, (3) the AVO strength, (4) the polarization product, and (5) the linear‐correlation coefficient. These different attributes can then be used to enhance AVO interpretation. Synthetic modeling for a succession of gas and brine layers encased in shale units indicates that the method can potentially be an effective hydrocarbon indicator. Application of the method to a real seismic dataset shows polarization anomalies associated with hydrocarbons.
