Identification of snowfall microphysical processes from Eulerian vertical gradients of polarimetric radar variables

Abstract. Polarimetric radar systems are commonly used to study the microphysics of precipitation. While they offer continuous measurements with a large spatial coverage, retrieving information about the microphysical processes that govern the evolution of snowfall from the polarimetric signal is challenging. The present study develops a new method, called process identification based on vertical gradient signs (PIVSs), to spatially identify the occurrence of the main microphysical processes (aggregation and riming, crystal growth by vapor deposition and sublimation) in snowfall from dual-polarization Doppler radar scans. We first derive an analytical framework to assess in which meteorological conditions the local vertical gradients of radar variables reliably inform about microphysical processes. In such conditions, we then identify regions dominated by (i) vapor deposition, (ii) aggregation and riming and (iii) snowflake sublimation and possibly snowflake breakup, based on the sign of the local vertical gradients of the reflectivity ZH and the differential reflectivity ZDR. The method is then applied to data from two frontal snowfall events, namely one in coastal Adélie Land, Antarctica, and one in the Taebaek Mountains in South Korea. The validity of the method is assessed by comparing its outcome with snowflake observations, using a multi-angle snowflake camera, and with the output of a hydrometeor classification, based on polarimetric radar signal. The application of the method further makes it possible to better characterize and understand how snowfall forms, grows and decays in two different geographical and meteorological contexts. In particular, we are able to automatically derive and discuss the altitude and thickness of the layers where each process prevails for both case studies. We infer some microphysical characteristics in terms of radar variables from statistical analysis of the method output (e.g., ZH and ZDR distribution for each process). We, finally, highlight the potential for extensive application to cold precipitation events in different meteorological contexts.
Partitioning soil organic carbon into its centennially stable and active fractions with machine-learning models based on Rock-Eval® thermal analysis (PARTYSOCv2.0 and PARTYSOCv2.0EU)

Abstract. Partitioning soil organic carbon (SOC) into two kinetically different fractions that are stable or active on a century scale is key for an improved monitoring of soil health and for more accurate models of the carbon cycle. However, all existing SOC fractionation methods isolate SOC fractions that are mixtures of centennially stable and active SOC. If the stable SOC fraction cannot be isolated, it has specific chemical and thermal characteristics that are quickly (ca. 1 h per sample) measurable using Rock-Eval® thermal analysis. An alternative would thus be to (1) train a machine-learning model on the Rock-Eval® thermal analysis data for soil samples from long-term experiments for which the size of the centennially stable and active SOC fractions can be estimated and (2) apply this model to the Rock-Eval® data for unknown soils to partition SOC into its centennially stable and active fractions. Here, we significantly extend the validity range of a previously published machine-learning model (Cécillon et al., 2018) that is built upon this strategy. The second version of this model, which we propose to name PARTYSOC, uses six European long-term agricultural sites including a bare fallow treatment and one South American vegetation change (C4 to C3 plants) site as reference sites. The European version of the model (PARTYSOCv2.0EU) predicts the proportion of the centennially stable SOC fraction with a root mean square error of 0.15 (relative root mean square error of 0.27) at six independent validation sites. More specifically, our results show that PARTYSOCv2.0EU reliably partitions SOC kinetic fractions at its northwestern European validation sites on Cambisols and Luvisols, which are the two dominant soil groups in this region. We plan future developments of the PARTYSOC global model using additional reference soils developed under diverse pedoclimates and ecosystems to further expand its domain of application while reducing its prediction error.
Clinical profile of Female Urinary Incontinence: A Hospital Based Study

Aim: To determine the prevalence of urinary incontinence of women attending gynaecology outdoor patient department. Method: It is a prospective cross sectional study conducted at Paropakar Maternity and Women’s Hospital for three months. Types of incontinence, their presentation, associated factors, age and parity were the variables studied. Data were analyzed by descriptive statistics. Results: Out of 950 gynaecological out-patients, 97 had urinary incontinence (10.2%); 34.1% were in 50-59 years and 37.2% were multipara. Stress urinary incontinence (SUI) was the most common incontinence (56.7%) followed by mixed urinary incontinence (22.7%) and urge urinary incontinence (20.6%). Common complaints were leakage during coughing (63.6%) and sneezing (18.2%) in SUI; urgency and frequency were main problem in mixed and urge urinary incontinence. Three-fourth cases had associated medical conditions and rest had gynecological factors. Conclusions: Urinary incontinence is common in the fifth decade of life of women and more than half had stress incontinence.
Learning Spanish as a foreign language through Music

Music has multiple characteristics that make it an ideal tool for teaching and learning languages. Although some research has been done on this subject, there are still many areas to explore. This quantitative research presents survey data from 178 students of Spanish as a Foreign Language to better understand how adult learners use music and other media in their practice of Spanish. Non-parametric statistical tests were carried out. Data showed participants used music more frequently than other media as a means to practice Spanish outside of the classroom, despite having difficulties understanding the lyrics. Also, musical training was found to be an indicator of a higher level of lyrical comprehension. It was concluded that the growing popularity of Spanish language music, changes in music consumption, and the democratization of listening platforms –along with the ability that songs have to generate well-being and to create links, as well as to represent the target culture– were decisive factors in the use of songs in the learning of Spanish as a foreign language.
THE QUALITY OF TUBERCULOSIS SERVICES IN PATIENTS’ PERSPECTIVES: A LITERATURE REVIEW

Background: The assessment from the patient's perspective is the assurance of TB service’ quality to achieve the "End TB" target. The information regarding TB services’ quality assessment in the dimensions of QUOTE TB Light is not widely found. Aims: The study aims to review TB services' quality from the patients’ perspective in the 7 dimensions of QUOTE TB Light. Methods: This literature review study searched from 3 databases, namely PubMed, Science-Direct, and Google Scholar since July October 2020. The inclusion criteria were research on TB services quality, patients’ perspective, and patient assessment of 7 dimenssion. Articles assessed the other health services’ quality and published before January 2015 was excluded. Results: A total of 7 from 89 articles found were selected for review. The patients’ assessments are based on their experiences or satisfactions. Most of the studies are satisfied with service availability, communication, patient-provider interactions, competence, and affordability. The patients’ dissatisfactions about infrastructure and stigma acquired during treatment. Conclusion: Infrastructure and stigma are assessed negatively. The continously evaluation and training for health workers need to be improved so they can serve patients well. The patients’ perspectives can be the major consideration for providers to enhance the TB services’ quality.
Effect of Simultaneous Integrated Boost Intensity Modulated Radiation Therapy (SIB-IMRT) and Non-Operative Strategy on Outcomes of Distal Rectal Cancer Patients with Clinically Positive Lateral Pelvic Lymph Node

Background: We aimed to analyze the effect of simultaneous integrated boost intensity modulated radiation therapy (SIB-IMRT) and non-operative treatment on the clinical outcomes of distal rectal cancer patients exhibiting clinically positive lateral pelvic lymph nodes (LPLNs). Methods: We reviewed the medical records of patients diagnosed as having distal rectal adenocarcinoma with clinically positive LPLNs (≥7 mm, with irregular borders or mixed signal intensity) using primary pelvic magnetic resonance imaging (MRI). These patients had received SIB-IMRT-based neoadjuvant chemoradiotherapy (NCRT) and non-operative treatment according to the heterogeneity of the disease or personal preference. Chi-square tests were used to compare data between the two groups. Progression-free survival (PFS) and local regrowth were evaluated using the Kaplan-Meier method. Results: Between 2016 and 2019, we analyzed 75 patients diagnosed as having clinically positive LPLNs using primary MRI. SIB-IMRT was delivered to the planning positive LPLNs (PGTVn) at a total dose of 56–60 Gy. After NCRT, 23 patients underwent non-operative treatment. Among these patients, the median short axis of LPLNs was 8 mm (range: 7–21 mm). Fifteen patients were categorized into the mesorectal fascia (MRF)-positive group. The median follow-up duration for these patients was 19.8 months, and no patient exhibited LPLN regrowth. The 2-year PFS rate was 85.6% for non-operative patients, 74.6% for operative patients, and 90.0% for the pathological complete response (pCR) subgroup. Eighteen patients who underwent non-operative treatment were included in the clinical complete response (cCR) subgroup. The 2-year PFS and local regrowth rates in this group were similar to those in patients with clinically negative LPLN who achieved cCR. During NCRT, 21 (28.0%) patients experienced grade 2–3 acute reversible toxicity. Conclusions: SIB-IMRT could eliminate metastases in LPLNs in a safe and effective manner, and non-operative strategies may be promising for cCR patients.
The Effect of Internal Control Entities to Determining the High of Audit fee

This research aimed to find out the direct effect of the internal control entities to determining the high of audit fee, and the indirect effect of the internal control entities to determining the high of audit fee through the extension of the auditor’s occupation. Data collection in this research used a questionnaire distributed to auditors who work in public accounting in Makassar. Analysis of the data used path analysis. The results of this research provided evidence that the internal control entities had a direct effect on determining the high of audit fee, and the internal control entities had a significant indirect effect through the extension of auditors’ occupation to determining the high of audit fee. The implication is if internal control entities are ineffective, it will affect the larger the extent of auditor’s, so it will be also affected to the highest of the amount in determining audit fee.
Phenolic compound profiles and antioxidant activity of Ruta chalepensis L. leaves, a spontaneous medicinal herb: influence of harvest zone (Western Algeria)

Natural plant extracts contain a variety of phenolic compounds, to which various biological activities are attributed. Ruta chalepensis, known as “Fidjel”, is widespread in the Algerian territory, which was selected in order to estimate its content of secondary metabolites (phenolic compounds, flavonoids, tannins), and its antioxidant activity (DPPH, FRAP). For this purpose, two methanolic extracts were prepared from the leaves of this plant, harvested from two different areas: Tessala mountains (Sidi-Bel-Abbes town) and Taougrite mountains (Chlef town), which crude extract yields are around of 12.4% and 20.1% respectively. The quantitative estimation of the different secondary metabolites showed that the methanolic extract of Tessala mountains (MER TES) is the richest in polyphenols (10.65±0.67 mg GAE/g), flavonoids (31.16 ± 0.55 mg CE/g), hydrolyzable tannins (0.78 ± 0.02 mg CE / g), and in condensed tannins (2.75 ± 0.10 mg CE/g). However, an antioxidant activity evaluation of the two extracts showed that, both fractions are active with a maximum IC50 of 68.41±9.98 μg/ml in (MER TES). On the other hand, the extract from that of the Taougrite Mountains (MER TAO) shows a stronger reducing activity than (MER TES); the difference remains not significant. In conclusion, the plant harvesting area, and the bioclimatic conditions might influence the Rutaceae leaf extracts content and quality of the same family.
Clinical Profiles and Complete Blood Count Could Not Identify Children Aged 3 to 36 Months Who Had Fever Without Source at High Risk for Bacteremia

Objectives: To evaluate the incidence and causes of occult bacteremia and whether clinical profiles and complete blood count could reliably identify high-risk-for-bacteremia children aged 3 to 36 months who had fever without source (FWS). Material and Methods: The medical data of children aged 3 to 36 months who presented with FWS for 1 to 7 days but with no clinical signs of sepsis and were subsequently hospitalized between January 2007 and December 2017 with one or more of the following high risk features, body temperature >39 degrees Celsius, inactive behavior, white blood cell (WBC) count >15,000 cells per cubic millimeter (cells/mm), absolute neutrophil count >10,000 cells/mm, or absolute band count >1,500 cells/mm, were recorded. Results: Bacteremia was found in 12 of 160 (7.5%) children with one or more of the high-risk features. The pathogens were non-typhoidal Salmonella (5 patients), Streptococcus pneumoniae (4 patients), and Salmonella Typhi (3 patients). None of the high-risk features could differentiate between children with and without bacteremia. Five of the 8 patients with Salmonella septicemia had normal WBC counts leading to delays in prescribing empirical antibiotics and none of them had complications. None of the 117 patients in the non-bacteremia group who did not receive antibiotics or discontinued them after negative hemoculture had complications during hospitalization. Conclusion: High-risk features could not help to identify occult bacteremia in children aged 3-36 months who had FWS.
Students’ Mathematics Self-Concept, Mathematics Anxiety and Mathematics Self-Regulated Learning during the Covid-19 Pandemic

Online learning during the Covid-19 pandemic requires lecturers to provide a stimulus that can increase student learning independence. However, not all lecturers and students are ready to carry out online learning, as a result, the anxiety factor for students is getting higher. In some studies, it is said that anxiety has a negative correlation with student self-concept. This study aims to find out how the mathematics self-concept (MSC), mathematics anxiety (MA), and mathematics learning independence (MSRL) of students are during the Covid19 pandemic. This research is quantitative descriptive. The population of this study was active students in the Mathematics and Mathematics Education study program. Data were collected using a cross-sectional survey technique with cluster sampling. The data analysis technique used descriptive statistical analysis, Spearman correlation analysis, and ordinal regression analysis. The results showed that the average student had a positive MSC, MA, and moderate MSRL. Students with negative MSC had a significant tendency to have a high MSRL than students with positive MSC. The increasing probability of students with negative MSC having a high MSRL is 0.5110 times better than students with positive MSC. MSC and MA have an effect of 7.9% on changes in the student's MSRL variable. Thus, during the Covid-19 pandemic mathematics self-concept directly affects changes in student learning independence, but not with math anxiety.
Effect of high pressure on mass transfer kinetics of granny smith apple

ABSTRACT The mass transfer kinetics during osmotic dehydration of granny smith apple slices in 60 Brix fructose and sucrose solution was studied at atmospheric pressure and at elevated pressure of 200–600 MPa at 40°C. The moisture and solute fractions in apple slices during osmotic dehydration under high pressure were predicted by Weibull frequency distribution model. The calculated effective moisture diffusivity values of apple slices suspended in fructose and sucrose solution during high-pressure treatment (0.1–600 MPa) were in the range of 6.35 × 10−10 to 3.60 × 10−9 m2/s and 7.96 × 10−10 to 4.32 × 10−9 m2/s, respectively.
Effects of dissolved oxygen concentrations on growth, survival and gonadal development of freshwater pearl mussel Lamellidens marginalis

The present study was conducted to evaluate the effects of dissolved oxygen concentrations on growth, survival and gonadal development of freshwater pearl mussel (Lamellidens marginalis). Twenty adult L. marginalis were exposed to each of the five different concentrations of dissolved oxygen (DO) i.e (T0, no aeration), and T1, T2, T3 and T4 with one, two, three and four air stone aerators, respectively in fifteen glass aquaria each containing 10L of pond water. DO concentrations were significantly higher in all the treatments compared to the control but there were no significant differences among the treatments. There were significant differences in the growth and survival rates between control and treatments. The relative growth rates (%) were significantly higher in the highest oxygen concentration (T4) compared to other treatments. The survival rate was zero in control (T0), whereas it was 66.67%, 70.00%, 71.67% and 73.33%, respectively for T1, T2, T3 and T4. On day-30, oocytes in T0 were found to be smaller in size, with developing acini and no previtellogenic oocytes; whereas in T1, T2, T3 and T4, previtellogenic oocytes and larger acini were evident. On day-60, vitellogenic oocytes along with few under-developed oocytes started to detach from the acini walls, as well as some already started migration to germinal duct on day-90. This indicates that ovaries of all the treatments were ripe and were ready to spawn between day-60 and -90. On day-30, secondary spermatocytes were observed in testicular acini in case of T0, whereas more developed and dense spermatids were evident in T1, T2, T3 and T4. These results indicate that testes were in late development stages in T0, whereas they were ripe in all the treatments. The current findings indicate that hypoxia slows down growth, reduces survival rate and retards development of reproductive organs in L. marginalis.
Concentration of Thiourea is effective in breaking the dormancy of potato (Solanum tuberosum L.) varieties

Received: 20 March 2021 Revised received: 21 May 2021 Accepted: 15 June 2021 Potato germination is highly sensitive to ecological conditions. High altitude and low annual average temperature result in tuber dormancy and poor sprouting. Dormancy has become a significant constraint for lowering potato production, which hinders the possibility of growing two crop cycles per year. An experiment was conducted from February to April 2020. Two major potato varieties (Desiree and Cardinal) were treated with four Thiourea concentrations (0, 1, 2, and 3%) in a two factorial, completely randomized block design with three replications. Tubers were soaked for 2 hours in different Thiourea solution as per treatments, air dried until excess solution was removed and kept in a dark room on plastic trays. With the progress of experiment dormancy breaking and sprouting parameters like early sprouting, dormancy breaking, sprout length and sprout density were recorded. It was found that Thiourea has a significant effect on all observed attributes as per varieties of potato. For Desiree variety, Thiourea (1%) decreased dormancy period by 22 days compared to control (Desiree*Thiourea 0%) and produced the longest average sprout of 7.36cm at 49 days after treatment (DAT). On the other hand, for the Cardinal variety, Thiourea (3%) decreased tuber dormancy by 27 days compared to control (Cardinal*Thiourea 0%) and produced sprout of 7.75 cm at 49 DAT. In case of sprouts/tuber 1% and 3% Thiourea produced 4.13 and 1.91 sprouts/tubers in Desiree and Cardinal, respectively. The overall mean finding indicate that, 1% and 3% Thiourea concentration was significantly superior for breaking dormancy and enhancing sprouting of potato varieties of Desiree and Cardinal respectively.
EVALUATING THE IMPACT OF LASRC AND SEN2COR ATMOSPHERIC CORRECTION ALGORITHMS ON LANDSAT-8/OLI AND SENTINEL-2/MSI DATA OVER AERONET STATIONS IN BRAZILIAN TERRITORY

Accurate and consistent Surface Reflectance estimation from optical remote sensor observations is directly dependant on the used atmospheric correction processor and the differences caused by it may have implications on further processes, e.g. classification. Brazil is a continental scale country with different biomes. Recently, new initiatives, as the Brazil Data Cube Project, are emerging and using free and open data policy data, more specifically medium spatial resolution sensor images, to create image data cubes and classify the Brazilian territory crops. For this reason, the purpose of this study is to verify, on Landsat-8 and Sentinel-2 images for the Brazilian territory, the suitability of the atmospheric correction processors maintained by their image providers, LaSRC from USGS and Sen2cor from ESA, respectively. To achieve this, we tested the surface reflectance products from Landsat-8 processed through LaSRC and Sentinel-2 processed through LaSRC and Sen2cor comparing to a reference dataset computed by ARCSI and AERONET. The obtained results point that Landsat-8/OLI images atmospherically corrected using the LaSRC corrector are consistent to the surface reflectance reference and other atmospheric correction processors studies, while for Sentinel-2/MSI images, Sen2cor performed best. Although corrections over Sentinel-2/MSI data weren’t as consistent as in Landsat-8/OLI corrections, in comparison to the surface reflectance references, most of the spectral bands achieved acceptable APU results.
Relation between Different Types of Treatment and Glycemic Control in Diabetic Pregnant Women

DOI: https://doi.org/10.53523/ijoirVol8I1ID47 Abstract Gestational diabetes mellitus (GDM) is a common medical condition associated with pregnancy. GDM is defined as hyperglycemia that is diagnosed during pregnancy and is not clearly overt diabetes that existed prior to pregnancy. The sample of the study was sixty diabetic pregnant women who came for follow up at obstetrics and gynecology department in TMC in Tripoli medical center during the year 2016. The patients divided according to the type of treatments they received into three groups; A: Patients who took Oral hypoglycemic agents (OHA), B: Patients who took insulin, C: Patents who took both drugs (OHA and insulin), Glycemic control was assessed using HBA1c level, FBS and RBS. This study shows that about 70% of the patients who took OHA had type 1 diabetes and 30% had type 2 diabetes. About 77.8% of patients who took insulin had type 2 diabetes and 22.2% had type 1 diabetes. And 73.2% of the patients who were treated with the combination of drugs had type 2 diabetes and 26.8% had type 1 diabetes. The current study demonstrates that 80% of patients who took OHA had good control, 33.3% of patients who took insulin had good control and 53.7% of patients who took both drugs had good control. Regarding the fasting blood sugar of the patients, the result illustrates the following; High level was reported in 20% of OHA group, 33.3% of insulin group and 31.7% of both drugs group. On the birth weight, the macrosomia (>4kg) was more in insulin group (33.3%) than other groups (10% of OHA and 31.7% of both drugs group). GDM is a condition that should be treated and prevented, as uncontrolled GDM can affect the mother and the fetal growth.
