    Objectives: Dietary antioxidant intake decreases the risk of many diseases. Hyperemesis gravidarum (HG) is the most common eating disorder during pregnancy. Therefore, the authors conducted this prospective and case control study to evaluate dietary antioxidant levels of women with HG and compare with healthy pregnant women. Material and Methods: This prospective case control study was conducted at a government hospital in the southeastern region of Turkey, from February 2010 to May 2010. A total of 100 pregnant women were included into the study. Dietary antioxidant levels (DAL) were measured according to the new 92-item antioxidant nutrient questionnaire developed by Satia et al (1). 50 women with HG and 50 healthy pregnant women were evaluated. Statistical analyses were carried out with statistical packages for SPSS 15.0 for Windows (SPSS Inc., Chicago, IL, USA). Results: There were no statistically significant differences between the groups regarding the age of the patients, gestational age, educational status, body height and weight (p>.05). Vitamin E, E equivalent, vitamin C, carotene and vitamin A levels were significantly lower in women with HG (pCel: Spożywanie antyoksydantów obniża ryzyko wielu chorób. Wymioty ciężarnych (HG) są najczęstszym zaburzeniem odżywiania w ciąży. Z tego powodu autorzy przeprowadzili badanie porównawcze przypadków celem oceny poziomu antyoksydantów u kobiet z wymiotami ciężarnych w porównaniu ze zdrowymi kobietami. Materiał i metody: Badanie przeprowadzono w szpitalu w południowowschodniej Turcji, w okresie od lutego 2010 do maja 2010 na 100 ciężarnych kobietach. Poziom antyoksydantów (DAL) mierzono według nowego 92-pytaniowego kwestionariusza dotyczącego spożycia antyoksydantów opracowanego przez Satia [1].

    With Singapore currently the world’s most natural capital (biocapacity) deficit alongside four other Association of Southeast Asian Nations (ASEAN) countries having varying degree of ecological deficit, i.e. Indonesia, Malaysia, the Philippines, and Thailand, it then offers a clear justification for a more scrutiny of the ASEAN states’ ecological footprint dynamics. To provide more insight on the drivers of ecological footprint in the overall panel and for each of the above-mentioned countries, the roles of economic complexity, average working hours, labour productivity, labour income share, and globalization were examined by employing the Dynamic Ordinary Least Squares Mean Group (DOLSMG) alongside the recently developed (non)time-variant Granger causality approaches. For the overall panel, the DOLSMGapproach established that labour productivity, labour income share, and globalization reduce the biocapacity deficit by improving ecological quality while economic complexity worsen the region’s environmental quality. Additionally, in the overall panel, there is Granger causality evidence from the average working hour, labour income share, labour productivity, globalization, and economic complexity to ecological footprint. Moreover, the results of the two Granger causality approaches are unanimous in evidence. For instance, average working hours per year is a significant causal of ecological footprint in all the sampled countries at varying periods. Specifically, there are Granger causalities: from labour productivity to ecological footprint in Malaysia, the Philippines, Singapore and Thailand; from globalization to ecological footprint in Malaysia, the Philippines, Singapore, and Thailand; from economic complexity to ecological footprint in Indonesia, Malaysia, the Philippines, Singapore, and Thailand, all at varying times.publishedVersio

    By looking at the technological advancement and climate change mitigation plan of the advanced economies, the current study examines the role of sustainable development aspects such as innovations, high technology export, labor productivity, capital stock, research and development (R&D), information and communication technology (ICT), capital stock, and energy use in mitigating environmental degradation for the selected panel of countries with the most investment in technology (China, Denmark, Finland, France, Israel, Korea, Hong Kong, Germany, Japan, Netherlands, Singapore, Sweden, United Kingdom, and United States) over the period 2000–2018. Foremost, the pooled ordinary least square (POLS) and random-effects (RE) generalized least squares (GLS) approaches provided additional interesting inferences. As such, the POLS result revealed that only capital stock in the panel countries shows a desirable environmental effect. At the same time, labor productivity, innovation, R&D, ICT, and energy further hamper ecological quality in the examined panel countries. Similarly, the GLS result largely affirms the POLS results, with only the capital stock among the explanatory variables showing evidence of emission mitigation effect in the panel. Additionally, the panel Granger causality result illustrates evidence of unidirectional causality only innovation, ICT, and capital stock to environmental degradation.publishedVersio

    Augmenting conversations through context-aware multimedia retrieval based on speech recognition

    Future’s environments will be sensitive and responsive to the presence of people to support them carrying out their everyday life activities, tasks and rituals, in an easy and natural way. Such interactive spaces will use the information and communication technologies to bring the computation into the physical world, in order to enhance ordinary activities of their users. This paper describes a speech-based spoken multimedia retrieval system that can be used to present relevant video-podcast (vodcast) footage, in response to spontaneous speech and conversations during daily life activities. The proposed system allows users to search the spoken content of multimedia files rather than their associated meta-information and let them navigate to the right portion where queried words are spoken by facilitating within-medium searches of multimedia content through a bag-of-words approach. Finally, we have studied the proposed system on different scenarios by using vodcasts in English from various categories, as the targeted multimedia, and discussed how it would enhance people’s everyday life activities by different scenarios including education, entertainment, marketing, news and workplace

    Objectives: To evaluate clinical outcomes of pregnancies in adolescent, advanced and reproductive women maternal age. Materials and methods: A total of 187 pregnant women were included into the study, 51 (27.27 %) were adolescent pregnancies, mean age 17.7±3.3 years (range, 14-18 years), 40 (21.29 %) advanced maternal age pregnancies, mean age 41.4±2.6 years (range, 39-50 years) and 96 (51.33 %), healthy controls, mean age 28.8±4.3 years (range, 19-37 years). The majority of the adolescent pregnant women were nulliparous, while all of the advanced age pregnant women were multiparous (mean gravidity 4.5±2.4; range, 6-12). Mean gravidity of the control group was 3.6± 1.7 (range, 1-12). Results: There was statistically significant difference among the groups regarding demographic characteristics. According to the Bonferroni method, there was statistically significant difference among the three groups. Adverse fetal features were statistically different among the groups and the odd ratios were higher in the advanced maternal age group. The odds ratios (95% CI) for lower Apgar scores (Apgar score 1 and 5) and low birth weight in adolescent maternal age and advanced maternal age group were as follows: 1.88 (1.27 - 2.78) vs. 2.46 (1.55 - 3.85), 2.17 (1.18 - 4.00) vs. 4.79 (3.02-6.69) and 1.39 (1.14 - 1.68) vs. 3.06 (1.59 - 5.88), respectively. Gestational age at birth showed minimal risk for adolescent age group but no risk was noted in the advanced age group. Conclusions: The present study showed that pregnancies in adolescent maternal age, advanced maternal age and reproductive maternal age are different from each other in terms of clinical characteristics. According to this study advanced maternal age pregnancies are more risky and more likely to have adverse fetal outcome.Cel: Ocena wyników położniczych u ciężarnych młodocianych oraz w wieku zaawansowanym i reprodukcyjnym. Materiał i metody: Do badania włączono 187 ciężarnych, 51 (27,27%) młodocianych, średnia wieku 17,7±3,3 lat (zakres 14-18 lat), 40 (21,29%) w zaawansowanym wieku, średnia wieku 41,4±2,6 lat (zakres 39-50 lat) i 96 (51,33%) zdrowych ciężarnych stanowiących grupę kontrolną, średnia wieku 28,8±4,3 lat (zakres 19-37 lat). Większość młodocianych ciężarnych była nieródkami, podczas gdy wszystkie starsze ciężarne były wieloródkami (średnia ilość ciąż 4,5±2,4; zakres 6-12). Średnia rodność w grupie kontrolnej wynosiła 3,6±1,7 (zakres 1-12). Wyniki: Znaleziono istotną statystycznie różnicę pomiędzy grupami dotyczącą cech demograficznych. Według metody Bonferroni różnica pomiędzy trzema badanymi grupami była istotna statystycznie. Niekorzystne wyniki położnicze oraz iloraz szans były wyższe u kobiet ciężarnych w zaawansowanym wieku. Ilorazy szans (95%CI) dla niższego wyniku w skali Agar (Agar 1 i 5) oraz niższej masy urodzeniowej w grupie młodocianych i grupie starszych ciężarnych wynosiły odpowiednio: 1,88 (1,27-2,78) vs. 2,46(1,55-3,85), 2,17(1,18-4,00) vs. 4,79 (3,02-6,69) i 1,39 ((1,14-1,68) vs. 3,06 (1,59-5,88). Wiek ciążowy w momencie porodu okazał się minimalnie istotnym czynnikiem ryzyka w grupie młodocianych a w grupie starszych ciężarnych nie obserwowano żadnego ryzyka. Wnioski: Badanie wykazało, że ciąże u młodocianych, u kobiet w starszym wieku oraz w wieku rozrodczym różnią się między sobą pod względem klinicznym. Według naszego badania ciąża u kobiety w starszym wieku jest obarczona większym ryzykiem niekorzystnych wyników położniczych

    Measurement of the Standard Model Processes for Supersymmetry Search in Low Momentum Single-Electron Events in the Vector Boson Fusion Topology at the LHC

    The yield of events with two jets, a single low-momentum electron, and large missing transverse momentum in the vector boson fusion (VBF) topology is measured in proton-proton collisions at center-of-mass energy of 13 TeV. The data corresponds to a total integrated luminosity of 35.86 fb⁻¹ collected in 2016 by the CMS detector at CERN’s Large Hadron Collider. The event selection requirements with electron’s transverse momentum of 10 GeV to 40 GeV are optimized for the production of charginos (χ⁻±₁) and next-to-lightest neutralinos (χ⁻⁰₂) in supersymmetry (SUSY) compressed mass-spectra scenarios where the mass difference (∆M) between χ⁻±₁ and lightest neutralino (χ⁻⁰₁) is small. The masses of sleptons (Ī) are assumed to be between χ⁻±₁ and χ⁻⁰₁. The measurements in the VBF topology in various control regions are performed for the first time at hadron collider experiments, and the observed events are consistent with expectations by the Standard Model (SM) processes. The results are used to predict the SM event yields in the signal region in a blind analysis, and to set limits on the SUSY production in the VBF topology. Expected lower limits at 95% CL on the χ⁻±₁ /χ⁻⁰₂ mass are reported for various ∆M values in a scenario, where the branching fraction of Ī → l + χ⁻⁰₁ is 1/3 for each lepton flavour. The expected limits will be compared with observed limits in the next phase of the blind analysis

    Colon Cancer

    Colorectal cancers (CRCs) are commonly diagnosed malignancy in both men and women. Although it is a common disease, mortality rates decrease with widespread use of screening methods and novel developments in surgery. Physical examination, abdomen and pelvic computerized tomography, and chest imaging are necessary for preoperative staging and surgical planning of a newly diagnosed colon cancer. CRCs usually develop from adenomatous polyps. Although curative treatment of localized colon cancer is surgery, endoscopic polypectomy is sufficient when severe dysplasia or carcinoma in situ is detected on a polyp surface. Total mesorectal excision and neoadjuvant chemoradiotherapy in rectum cancers resulted in significant reductions in morbidity, mortality, and recurrence rates. Recently, complete mesocolic excision and central vascular ligation method has been described in the surgical treatment of colon cancer to achieve similar results. Unfortunately, metastatic colon cancer rate at presentation is approximately 20%. Surgery is a potentially curative option in selected patients with liver and lung metastasis. Pathologic stage of the tumor at presentation is the most important prognostic factor after resection. Therefore, early diagnosis of colon cancer by screening methods and new surgical techniques will lead to better results in survival rates

    Heat convection from the uniformly heated walls of a straight channel in presence of a rotationally oscillating cylinder (ROC) is simulated at Re = 100. Heat transfer enhancement due to vortex shedding from the ROC is investigated. Systematic studies are performed to explore the rotation angle and frequency influences on heat transfer by varying the latter in range of the lock-in regime and the former from 0 to 2 π/3. All simulation results are based on the numerical solutions of two-dimensional, unsteady, incompressible Navier-Stokes and energy equations using an h/p type finite element algorithm. Considering time periodicity of the resulting flow and temperature fields, time averaged wall Nusselt number is reported to quantify the heat transfer enhancement for Pr = 0.1, 1.0, 5.0 and 10.0 fluids. Performance analyses of the ROC device based on its total power consumption and heat transfer enhancement are also presented
