QUICK REFERENCE GUIDE Latitude, Longitude and Associated Metadata
QUICK REFERENCE GUIDE Latitude, Longitude and Associated Metadata The Property Profile Form (PPF) requests the property name, address, city, state and zip. From these address fields, ACRES interfaces with Google Maps and extracts the latitude and longitude (lat/long) for the property location. ACRES sets the remaining property geographic information to default values. The data (known collectively as “metadata”) are required by EPA Data Standards. Should an ACRES user need to be update the metadata, the Edit Fields link on the PPF provides the ability to change the information. Before the metadata were populated by ACRES, the data were entered manually. There may still be the need to do so, for example some properties do not have a specific street address (e.g. a rural property located on a state highway) or an ACRES user may have an exact lat/long that is to be used. This Quick Reference Guide covers how to find latitude and longitude, define the metadata, fill out the associated fields in a Property Work Package, and convert latitude and longitude to decimal degree format. This explains how the metadata were determined prior to September 2011 (when the Google Maps interface was added to ACRES). Definitions Below are definitions of the six data elements for latitude and longitude data that are collected in a Property Work Package. The definitions below are based on text from the EPA Data Standard. Latitude: Is the measure of the angular distance on a meridian north or south of the equator. Latitudinal lines run horizontal around the earth in parallel concentric lines from the equator to each of the poles. -

Published online: 2019-09-02 Original Article Association between Indoor Air Pollution and Cognitive Impairment among Adults in Rural Puducherry, South India Yuvaraj Krishnamoorthy, Gokul Sarveswaran, K. Sivaranjini, Manikandanesan Sakthivel, Marie Gilbert Majella, S. Ganesh Kumar Department of Preventive and Background: Recent evidences showed that outdoor air pollution had significant Social Medicine, Jawaharlal influence on cognitive functioning of adults. However, little is known regarding the Institute of Postgraduate Medical Education and association of indoor air pollution with cognitive dysfunction. Hence, the current study was done to assess the association between indoor air pollution and cognitive Research, Puducherry, India Abstract impairment among adults in rural Puducherry. Methodology: A community‑based cross‑sectional study was done among 295 adults residing in rural field practice area of tertiary care institute in Puducherry during February and March 2018. Information regarding sociodemographic profile and household was collected using pretested semi‑structured questionnaire. Mini‑Mental State Examination was done to assess cognitive function. We calculated adjusted prevalence ratios (aPR) to identify the factors associated with cognitive impairment. Results: Among 295 participants, 173 (58.6) were in 30–59 years; 154 (52.2%) were female; and 59 (20.0%) were exposed to indoor air pollution. Prevalence of cognitive impairment in the general population was 11.9% (95% confidence interval [CI]: 8.7–16.1). Prevalence of cognitive impairment among those who were exposed to indoor air pollution was 27.1% (95% CI: 17.4–39.6). Individuals exposed to indoor air pollution (aPR = 2.18, P = 0.003) were found to have two times more chance of having cognitive impairment. -
A Stability Analysis of Divergence Damping on a Latitude–Longitude Grid
2976 MONTHLY WEATHER REVIEW VOLUME 139 A Stability Analysis of Divergence Damping on a Latitude–Longitude Grid JARED P. WHITEHEAD Department of Mathematics, University of Michigan, Ann Arbor, Ann Arbor, Michigan CHRISTIANE JABLONOWSKI AND RICHARD B. ROOD Department of Atmospheric, Oceanic and Space Sciences, University of Michigan, Ann Arbor, Ann Arbor, Michigan PETER H. LAURITZEN Climate and Global Dynamics Division, National Center for Atmospheric Research,* Boulder, Colorado (Manuscript received 24 August 2010, in final form 25 March 2011) ABSTRACT The dynamical core of an atmospheric general circulation model is engineered to satisfy a delicate balance between numerical stability, computational cost, and an accurate representation of the equations of motion. It generally contains either explicitly added or inherent numerical diffusion mechanisms to control the buildup of energy or enstrophy at the smallest scales. The diffusion fosters computational stability and is sometimes also viewed as a substitute for unresolved subgrid-scale processes. A particular form of explicitly added diffusion is horizontal divergence damping. In this paper a von Neumann stability analysis of horizontal divergence damping on a latitude–longitude grid is performed. Stability restrictions are derived for the damping coefficients of both second- and fourth- order divergence damping. The accuracy of the theoretical analysis is verified through the use of idealized dynamical core test cases that include the simulation of gravity waves and a baroclinic wave. The tests are applied to the finite-volume dynamical core of NCAR’s Community Atmosphere Model version 5 (CAM5). Investigation of the amplification factor for the divergence damping mechanisms explains how small-scale meridional waves found in a baroclinic wave test case are not eliminated by the damping. -

The First Line in the Above Code Defines a New Variable Called “Anemic”; the Second Line Assigns Everyone a Value of (-) Or No Meaning They Are Not Anemic
The first line in the above code Defines a new variable called “anemic”; the second line assigns everyone a value of (-) or No meaning they are not anemic. The first and second If commands recodes the “anemic” variable to (+) or Yes if they meet the specified criteria for hemoglobin level and sex. A Note to Epi Info DOS users: Using the DOS version of Epi you had to be very careful about using the Recode and If/Then commands to avoid recoding a missing value in the original variable to a code in the new variable. In the Windows version, if the original value is missing, then the new variable will also usually be missing, but always verify this. Always Verify Coding It is recommended that you List the original variable(s) and newly defined variables to make sure the coding worked as you expected. You can also use the Tables and Means command for double-checking the accuracy of the new coding. Use of Else … The Else part of the If command is usually used for categorizing into two groups. An example of the code is below which separates the individuals in the viewEvansCounty data into “younger” and “older” age categories: DEFINE agegroup3 IF AGE<50 THEN agegroup3="Younger" ELSE agegroup3="Older" END Use of Parentheses ( ) For the Assign and If/Then/Else commands, for multiple mathematical signs, you may need to use parentheses. In a command, the order of mathematical operations performed is as follows: Exponentiation (“^”), multiplication (“*”), division (“/”), addition (“+”), and subtraction (“-“). For example, the following command ASSIGNs a value to a new variable called calc_age based on an original variable AGE (in years): ASSIGN calc_age = AGE * 10 / 2 + 20 For example, a 14 year old would have the following calculation: 14 * 10 / 2 + 20 = 90 First, the multiplication is performed (14 * 10 = 140), followed by the division (140 / 2 = 70), and then the addition (70 + 20 = 90). -

Diagnostic Value of Alpha-Fetoprotein Combined with Neutrophil-To
Hu et al. BMC Gastroenterology (2018) 18:186 https://doi.org/10.1186/s12876-018-0908-6 RESEARCH ARTICLE Open Access Diagnostic value of alpha-fetoprotein combined with neutrophil-to-lymphocyte ratio for hepatocellular carcinoma Jian Hu1†, Nianyue Wang2†, Yongfeng Yang2,LiMa2, Ruilin Han3, Wei Zhang4, Cunling Yan3*, Yijie Zheng5* and Xiaoqin Wang1* Abstract Background: To investigate the diagnostic performance of alpha-fetoprotein (AFP) and neutrophil-to-lymphocyte ratio (NLR) as well as their combinations with other markers. Methods: Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), AFP and levels as well as the numbers of neutrophils and lymphocytes of all enrolled patients were collected. The NLR was calculated by dividing the number of neutrophils by the number of lymphocytes. Receiver operating characteristic (ROC) curve analysis was conducted to determine the ability of each marker and combination of markers to distinguish HCC and liver disease patients. Results: In total, 545 patients were included in this study. The area under the ROC curve (AUC) values for AFP, ALT, AST, and NLR were 0.775 (0.738–0.810), 0.504 (0.461–0.547), 0.660 (0.618–0.699), and 0.738 (0.699–0.774) with optimal cut-off values of 24.6 ng/mL, 111 IU/mL, 27 IU/mL, and 2.979, respectively. Of the four biomarkers, AFP and NLR showed comparable specificity (0.881 and 0.858) and sensitivity (0.561 and 0.539). The combination of AFP and NLR showed the highest AUC (0.769) with a significantly higher sensitivity (0.767) and a lower specificity (0.773) compared to AFP or NLR alone, and it had the highest sum of sensitivity and specificity (1.54) among all combinations. -
Time Signal Stations 1By Michael A
122 Time Signal Stations 1By Michael A. Lombardi I occasionally talk to people who can’t believe that some radio stations exist solely to transmit accurate time. While they wouldn’t poke fun at the Weather Channel or even a radio station that plays nothing but Garth Brooks records (imagine that), people often make jokes about time signal stations. They’ll ask “Doesn’t the programming get a little boring?” or “How does the announcer stay awake?” There have even been parodies of time signal stations. A recent Internet spoof of WWV contained zingers like “we’ll be back with the time on WWV in just a minute, but first, here’s another minute”. An episode of the animated Power Puff Girls joined in the fun with a skit featuring a TV announcer named Sonny Dial who does promos for upcoming time announcements -- “Welcome to the Time Channel where we give you up-to- the-minute time, twenty-four hours a day. Up next, the current time!” Of course, after the laughter dies down, we all realize the importance of keeping accurate time. We live in the era of Internet FAQs [frequently asked questions], but the most frequently asked question in the real world is still “What time is it?” You might be surprised to learn that time signal stations have been answering this question for more than 100 years, making the transmission of time one of radio’s first applications, and still one of the most important. Today, you can buy inexpensive radio controlled clocks that never need to be set, and some of us wear them on our wrists. -
Latitude and Longitude
Latitude and Longitude Finding your location throughout the world! What is Latitude? • Latitude is defined as a measurement of distance in degrees north and south of the equator • The word latitude is derived from the Latin word, “latus”, meaning “wide.” What is Latitude • There are 90 degrees of latitude from the equator to each of the poles, north and south. • Latitude lines are parallel, that is they are the same distance apart • These lines are sometimes refered to as parallels. The Equator • The equator is the longest of all lines of latitude • It divides the earth in half and is measured as 0° (Zero degrees). North and South Latitudes • Positions on latitude lines above the equator are called “north” and are in the northern hemisphere. • Positions on latitude lines below the equator are called “south” and are in the southern hemisphere. Let’s take a quiz Pull out your white boards Lines of latitude are ______________Parallel to the equator There are __________90 degrees of latitude north and south of the equator. The equator is ___________0 degrees. Another name for latitude lines is ______________.Parallels The equator divides the earth into ___________2 equal parts. Great Job!!! Lets Continue! What is Longitude? • Longitude is defined as measurement of distance in degrees east or west of the prime meridian. • The word longitude is derived from the Latin word, “longus”, meaning “length.” What is Longitude? • The Prime Meridian, as do all other lines of longitude, pass through the north and south pole. • They make the earth look like a peeled orange. The Prime Meridian • The Prime meridian divides the earth in half too. -
