Background: According to a national survey in 2014, the prevalence of overweight and obesity among Saudi women is reaching 33.5%. Instead of adopting healthy lifestyle, this population may adopt some weight management practices (WMP) which might be unhealthy and some could lead to serious health issues. Aim: To compare lifestyle patterns and WMP adopted by obese and normal weight Saudi females by assessing the difference in energy and macronutrients intake, dietary habits, level of physical activity and WMP. Methods: Through a cross-sectional study among female students at Princess Nourah Bint Abdulrahman University (PNU) (Riyadh – KSA.), 200 participants were conveniently selected, assigned in two groups: in obese and normal weight (each group have 100 students), based on their BMI, according to the WHO cut-off values. Data collected, through questionnaire and analysis, were analyzed using SPSS program. Chi-square and t-test were used to assess the difference between the two groups. Results: Unhealthy WMP were high among obese students. Total calorie intake was not different; however, fat intake was higher in obese group (p < 0.01). Level of moderate active was higher in normal group than obese group (33 % versus 19 %, respectively). Food frequency consumption showed that fruit, date, and dressing were higher in obese group compared to normal weight group (p = 0.02, 0.01 and 0.03). Conclusions: Obese PNU female students adopt unhealthy WMP besides their inadequate nutritional intake and unhealthy dietary habits. Increasing awareness about the healthy lifestyle to manage weight is urgently needed.

Published: May 2021

Erythema multiforme is an immune-mediated mucocutaneous disorder. Mucosal involvement usually affects the oral region, the genitals or the eyes. We report a case of esophagitis caused by erythema multiforme in a patient diagnosed with lung cancer. Esophageal manifestation in erythema multiforme is rarely seen. Besides esophagitis it can lead to esophageal strictures. Erythema multiforme is mostly triggered by infection or drugs but the association with malignancy has been described.

Published: May 2021

Background and study aims : The international consensus Fukuoka guideline (Fukuoka ICG), The European evidence-based guideline on pancreatic cystic neoplasms (European EBG) and the American Gastroenterological Association institute guideline on the diagnosis and management of asymptomatic neoplastic pancreatic cysts (AGA IG) are 3 frequently cited guidelines for the risk stratification of neoplastic pancreatic cysts. The aim of this study was to assess the accuracy of detecting malignant cysts by strictly applying these guidelines retrospectively to a cohort of surgically resected pancreatic cysts.

Patient and methods : 72 resected cysts were included in the analysis. Invasive carcinoma, high grade dysplasia and neuroendocrine tumour were considered as “malignant cysts” for the purpose of the study.

Results : 32% of the resected cysts were malignant. The analysis showed that the Fukuoka ICG, European EBG and AGA IG had a sensitivity of 66,8%, 95,5%, 80%; a specificity of 26,8%, 11,3%, 43,8%; a positive predictive value of 31,8%, 35%, 47,1% and a negative predicted value of 61,1%, 83,3%, 77,8% respectively. The missed malignancy rate was respectively 11,3%, 1,5%, 7,7% and surgical overtreatment was respectively 48,4%, 59,1%, 34,6%.

Conclusion : In this retrospective analysis, the European EBG had the lowest rate of missed malignancy at the expense of a high number of “unnecessary” resections. The Fukuoka ICG had the highest number of missed malignancy. The AGA IG showed the lowest rate of unnecessary surgery at the cost of a high number of missed malignancy. There is need to develop better biomarkers to predict the risk of malignancy.

Background and study aims : Inadequate bowel preparation inpatients scheduled for colonoscopy is an important problem. Inour study, we aimed to investigate the effect of physician-providedbowel preparation education on the quality of bowel preparationand process.

Patients and methods : A total of 150 outpatients who were referredto Kocaeli University Medical Faculty Hospital GastroenterologyUnit for colonoscopy between May 2019 and October 2019 wereenrolled in our prospective, endoscopist-blinded study. Patientswere divided into two groups. Group 1 (education group) included73 patients who received 10 minutes of verbal information froma physician in addition to a written information form. Group 2(control group) included 75 patients who received informationfrom a medical secretary in addition to a written information form.During colonoscopy, the quality of bowel preparation was assessedusing the Boston bowel preparation scale (BBPS). A BBPS score≥ 5 was considered adequate bowel preparation. The mean BBPSscore, polyp detection rate, cecal intubation rate and time, andprocedure time were also evaluated.

Results : The rate of adequate bowel preparation (BBPS score≥ 5) was 90.4% and 74.7% in groups 1 and 2, respectively (p =0.021). The odds ratio for having a BBPS score ≥ 5 in the educationgroup was 3.199 compared with the control group (95% confidenceinterval = 1.254-8.164; p = 0.015). The cecal intubation rates were91.8% and 88% in groups 1 and 2, respectively (p > 0.05). The cecalintubation time, procedure time, and adenoma detection rates weresimilar between the groups. The relationships of age, educationlevel, sex, diabetes mellitus, medicine use, procedure time, andintraabdominal surgery with inadequate bowel preparationwere analysed using a logistic regression model. Univariate andmultivariate analyses revealed no significant factors associatedwith inadequate bowel preparation.

Conclusions : Patient education on the bowel preparationprocess via a physician improved the quality of bowel preparation.
Regression of multiple hepatocellular adenomas after cessation of oral contraceptive pills : a case report and review of the current literature
Authors: Moors G , Poels H , Vandecaveye V , Roskams T , Verslype C
Published: May 2021

Hepatocellular adenoma (HCA) is an uncommon benign liver neoplasm usually solitary and identified incidentally on imaging. We report a case of a 50-year old female who was diagnosed with multiple hepatic adenomas of the inflammatory subtype. After discontinuation of oral contraception a decrease of both the number and size of the liver lesions was seen on magnetic resonance imaging (MRI) without the need of further intervention. The major challenge in the clinical management of patients with multiple HCAs resides in the risk assessment for future complications. In the case of multiple HCAs subtype seemed to be more relevant than the actual number of lesions. Because little is known about the natural evolution in patients with multiple HCAs, we performed a review of the current literature with focus on the different subtypes and their clinical relevance.
Measurement Report: Variability in the composition of biogenic volatile organic compounds in a southeastern US forest and their role in atmospheric reactivity

Published: May 2021

Abstract. Despite the significant contribution of biogenic volatile organic compounds (BVOCs) to organic aerosol formation and ozone production and loss, there are few long-term, year-round, ongoing measurements of their concentrations and their impacts on atmospheric reactivity. To address this gap, we present one year of hourly measurements of chemically resolved BVOCs between September 15, 2019, and September 15, 2020, collected at a research tower in Central Virginia in a mixed forest representative of ecosystems in the Southeastern U.S. Concentrations of isoprene, isoprene reaction products, monoterpenes, and sesquiterpenes are described and examined for their impact on hydroxy radical (OH), ozone, and nitrate reactivity. Concentrations of isoprene range from negligible in the winter to typical summertime 24-hour averages of 4–6 ppb, while monoterpenes have more stable concentrations in the range of tenths of a ppb up to ~ 1 ppb year-round. Sesquiterpenes are typically observed at concentrations of < 10 ppt, but this represents a lower bound in their abundance. In the growing season, isoprene dominates OH reactivity but is less important for ozone and nitrate reactivity. Monoterpenes are the most important BVOCs for ozone and nitrate reactivity throughout the year and for OH reactivity outside of the growing season. To better understand the impact of this compound class on OH, ozone, and nitrate reactivity, the role of individual monoterpenes is examined. Despite the dominant contribution of α-pinene to total monoterpene mass, the average rate constants for reaction of the monoterpene mixture with atmospheric oxidants is between 20% and 30% faster than α-pinene due to the contribution of more-reactive but less abundant compounds. A majority of reactivity comes from α-pinene and limonene (the most significant low-concentration, high-reactivity isomer), highlighting the importance of both concentration and structure in assessing atmospheric impacts of emissions.
Was there a volcanic induced long lasting cooling over the Northern Hemisphere in the mid 6th–7th century?
Authors: van Dijk Evelien , Jungclaus Johann , Lorenz Stephan , Timmreck Claudia , Krüger Kirstin
Published: May 2021

Abstract. The climate in the Northern Hemisphere (NH) of the mid-6th century was one of the coldest during the last two millennia. The onset of this cold period is attributed to the volcanic double eruption event in 536 and 540 Common Era (CE) based on multiple paleo-proxies. Recently, there has been a debate about how long lasting and cold this volcanic induced cold period actually was. To better understand this, we analyze new transient simulations over the Common Era and enhance the representation of mid 6th to 7th century climate by additional ensemble simulations covering 520–680 CE. We use the Max Planck Institute Earth System Model and apply external forcing as recommended in the Paleo Model Intercomparison Project, Phase 4. After the four large eruptions in 536, 540, 574, and 626 CE, a significant surface climate response up to 20 years is simulated. The Northern Hemisphere 2 m air temperature, and precipitation decreases up to 2 K, and 0.2 mm day−1, respectively, and sea ice area increases up to 1.5 x 1012 m2. The global ocean heat content decreases drastically by 1.5 x 1023 Jm−1, which is significant for 30–40 years, and does not totally recover during the entire study period. The surface maps reveal atmospheric circulation changes with a hemispheric dipole pattern and land see contrast in the first two years after the eruptions. Poleward of ∼ 45° N higher sea level pressure and a decrease in hydrological variables occur, accompanied by a land see contrast, with decreased values over land and an increase in values over the ocean, which is especially pronounced for evaporation during boreal summer. During boreal winter, a positive North Atlantic Oscillation develops in the first year after (three out of the four) large eruptions. Analysing underlying mechanisms in the North Atlantic reveals that complex interaction between sea-ice expansion, changes in barotropic streamfunction and meridional overturning circulation leads to a reduction in the ocean heat transport, which then further enhances sea ice expansion impacting NH surface climate up to 20 years. Temperature records reconstructed from tree-rings in the NH agree well with the model simulations and show a similar ∼20 year cooling after the eruptions. A century of surface cooling starting in the mid-6th century, as shown from local tree-ring records from the Alps and Altai, does not occur in our volcanic climate model simulations, nor in the NH tree-ring compilation.
A composite 10Be, IR-50 and 14C chronology of the pre-Last Glacial Maximum (LGM) full ice extent of the western Patagonian Ice Sheet on the Isla de Chiloé, south Chile (42° S)

Published: May 2021

Abstract. Unanswered questions about the glacier and climate history preceding the
global Last Glacial Maximum (LGM) in the southern temperate latitudes
remain. The Marine Isotope Stage (MIS) 3 is normally understood as a global
interstadial period; nonetheless its climate was punctuated by conspicuous
variability, and its signature has not been resolved beyond the polar realms. In this paper, we compile a 10Be depth profile, single grain infrared (IR) stimulated luminescence dating and 14C samples to derive a new glacier record for the principal outwash plain complex, deposited by the western Patagonian Ice Sheet (PIS) during the last glacial period (Llanquihue Glaciation) on the Isla de Chiloé, southern Chile (42∘ S). In this region, the Golfo de Corcovado Ice Lobe
left a distinct geomorphic and stratigraphic imprint, suitable for
reconstructing former ice dynamics and timing of past climate change. Our data
indicate that maximum glaciation occurred by 57.8±4.7 ka without
reaching the Pacific Ocean coast. Ice readavanced and buttressed against the
eastern side of the Cordillera de la Costa again by 26.0±2.9 ka. Our
data further support the notion of a large ice extent during parts of the MIS 3 in Patagonia and New Zealand but appear to contradict near contemporaneous
interstadial evidence in the southern midlatitudes, including
Chiloé. We propose that the PIS expanded to its full-glacial Llanquihue
moraines, recording a rapid response of southern mountain glaciers to the
millennial-scale climate stadials that punctuated the MIS 3 at the poles and elsewhere.
Saline groundwater evolution in Luanhe River Delta, China since Holocene: hydrochemical, isotopic and sedimentary evidence

Published: May 2021

Abstract. Since the Quaternary Period, palaeo-seawater intrusions have been suggested to explain the observed saline groundwater that extends far inland in coastal zones. The Luanhe River Delta (northwest coast of Bohai Sea, China) is characterized by the distribution of saline, brine, brackish and fresh groundwater, from coastline to inland, with a wide range of total dissolved solids (TDS) between 0.38–125.9 g L−1. Meanwhile, previous studies have revealed that this area was significantly affected by Holocene marine transgression. In this study, we used hydrochemical, isotopic, and sedimentological methods to investigate groundwater salinization processes in the Luanhe River Delta and its links to the palaeo-environmental settings. The isotopic results (2H, 18O, 14C) show that deep confined groundwater was recharged during the Late Pleistocene cold period, shallow saline and brine groundwater was recharged during the warm Holocene period, and shallow brackish and fresh groundwater was mainly recharged by surface water. The results of hydro-geochemical modeling (PHREEQC) suggest that the salty sources of salinization are seawater and concentrated saline water (formed after evaporation of seawater). The 18O–Cl relationship diagram shows that saline and brine groundwater are formed by three end-member mixings (seawater, concentrated saline water and, fresh groundwater). In contrast, brackish groundwater is formed after the wash-out of saline groundwater by surface water. Using palaeo-environmental data from sediments, we found that palaeo-seawater intrusion during the Holocene marine transgression was the primary cause of groundwater salinization in the study region. Seawater was found to evaporate in the lagoon area during the progradation of the Luanhe River Delta; the resulting concentrated saline water infiltrated into the aquifer, eventually forming brine groundwater due to salinity accumulation. Surface water recharge and irrigation, on the other side, would gradually flush the delta plain's saline groundwater. This study provides a better understanding of saline groundwater evolution in other similar coastal zones.
Vibroacoustic characteristics analysis of a planetary gear reducer considering the exterior housing structure

Published: May 2021

Abstract. Previous studies have attempted to identify weak links in the dynamic characteristics of the planetary gear reducer (PGR) exterior body structure (EBS). Through numerical simulation, these studies analyzed the mode and natural frequencies and the vibration types of each order of the EBS. However, these scholars have never focused on the main factors affecting the dynamic characteristics of the EBS of this subject. This study in the topic has analyzed the vibroacoustic characteristics of an EBS and optimized its design using numerical simulation. Herein, the contribution of the vibration transfer path from the excitation points on the exterior body to the machine foot is emphatically revealed, and the influences of the main structural parameters on the transfer characteristics are discussed. An optimal EBS for a PGR with lower acoustic vibrations is designed in detail, and a composite EBS with damping vibration attenuation and acoustic absorption is proposed. The radiation acoustic characteristics without acoustic protection and damping materials are analyzed. These research results are implemented in order to realize the dynamic characteristics, transmission, and radiation acoustic characteristics as objects of optimization, and the structural design parameters of the PGR exterior body are deeply optimized using dynamic modification and sensitivity analysis. This topic focuses on the vibroacoustic coupling of EBS in stationary fluid and average flow field. Based on the analysis method of theoretical modeling and numerical calculation, the EBS dynamic response and vibroacoustic characteristics under the action of frontal excitation external acoustic flow field are studied, which will be beneficial to explore the comprehensive optimization design of PGR dynamic and vibroacoustic properties.
Programming piston displacements for constant flow rate piston pumps with trigonometric transition functions
Authors: Tian Zhongxu , Lin Xingxing
Published: May 2021

Abstract. An analytical method for programming piston displacements for constant flow rate piston pumps is presented. A total of two trigonometric transition functions are introduced to express the piston velocities during the transition processes, which can guarantee both constant flow rates and the continuity of piston accelerations. A kind of displacement function of pistons, for two-piston pumps, and two other kinds, for three-piston pumps, are presented, and the physical meaning of their parameters is also discussed. The results show that, with the given transition functions, cam profiles can be designed analytically with parameterized forms, and the maximum accelerations of the pistons are determined by the width of the transition domain and the rotational velocities of the cams, which will affect contact forces between cams and followers.
Defining Southern Ocean fronts using unsupervised classification
Authors: Thomas Simon D. A. , Jones Daniel C. , Faul Anita , Mackie Erik , Pauthenet Etienne
Published: May 2021

Abstract. Oceanographic fronts are transitions between thermohaline structures with different characteristics. Such transitions are ubiquitous, and their locations and properties affect how the ocean operates as part of the global climate system. In the Southern Ocean, fronts have classically been defined using a small number of continuous, circumpolar features in sea surface height or dynamic height. Modern observational and theoretical developments are challenging and expanding this traditional framework to accommodate a more complex view of fronts. Here we present a complementary new approach for calculating fronts using an unsupervised classification method called Gaussian mixture modelling and a novel inter-class parameter called the I-metric. The I-metric approach produces a probabilistic view of front location, emphasising the fact that the boundaries between water masses are not uniformly sharp across the entire Southern Ocean. The I-metric approach uses thermohaline information from a range of depth levels, making it more general than approaches that only use near-surface properties. We train the statistical model on data from an observationally-constrained state estimate for more uniform spatial and temporal coverage. The probabilistic boundaries appear to be relatively sharp in the open ocean and somewhat diffuse near large topographic features, possibly highlighting the importance of topographically-induced mixing. For comparison with a more localised method, we use edge detection in principal component space and correlate the edges with surface velocities. The I-metric approach may prove to be a useful method for inter-model comparison, as it uses the thermohaline structure of those models instead of tracking somewhat ad-hoc values of sea surface height and/or dynamic height, which can vary considerably between models. In addition, the general I-metric approach allows front definitions to shift with changing temperature and salinity structures, which may be useful for characterising fronts in a changing climate.
Uncertainties in projected surface mass balance over the polar ice sheets from downscaled EC-Earth models
Authors: Boberg Fredrik , Mottram Ruth , Hansen Nicolaj , Yang Shuting , Langen Peter L.
Published: May 2021

Abstract. The future rates of ice sheet melt in Greenland and Antarctica are an important factor when making estimates of the likely rate of sea level rise. Global climate models that took part in the fifth Coupled Model Intercomparison Project (CMIP5) have generally been unable to replicate observed rates of ice sheet melt. With the advent of the sixth Coupled Model Intercomparison Project (CMIP6), with a general increase in the equilibrium climate sensitivity, we here compare two versions of the global climate model EC-Earth using the regional climate model HIRHAM5 downscaling EC-Earth for Greenland and Antarctica. One version (v2) of EC-Earth is taken from CMIP5 for the high-emissions Representative Concentration Pathways (RCP8.5) scenario and the other (v3) from CMIP6 for the comparable high-emissions Shared Socioeconomic Pathways (SSP5-8.5) scenario). For Greenland, we downscale the two versions of EC-Earth for the historical period 1991–2010 and for the scenario period 2081–2100. For Antarctica, the periods are 1971–2000 and 2071–2100, respectively. For the Greenland Ice Sheet, we find that the mean change in temperature is 5.9 °C when downscaling EC-Earth v2 and 6.8 °C when downscaling EC-Earth v3. Corresponding values for Antarctica are 4.1 °C for v2 and 4.8 °C for v3. The mean change in surface mass balance at the end of the century under these high emissions scenarios is found to be −210 Gt yr−1 (v2) and −1150 Gt yr−1 (v3) for Greenland and 420 Gt yr−1 (v2) and 80 Gt yr−1 (v3) for Antarctica. These distinct differences in temperature change and particularly surface mass balance change are a result of the higher equilibrium climate sensitivity in EC-Earth v3 (4.3 K) compared with 3.3 K in EC-Earth v2 and the differences in greenhouse gas concentrations between the RCP8.5 and the SSP5-8.5 scenarios.

This study aims to examine the effect of the audit committee, the board of commissioners and the board of directors on the company's financial performance. This study aims to prove this influence on the company's success rate in carrying out its operational activities. The population in this study are manufacturing companies in the consumer goods sector listed on the IDX in 2017-2019. The sampling method uses purposive sampling, which is a sampling technique with certain considerations. The research sample was 23 in 3 years with a total of 69 samples. The data analysis method used classical assumption test and multiple linear regression.

The results of this study indicate that the board of commissioners has a significant effect on the company's financial performance, meaning that a large size of the board of commissioners causes better management monitoring and can minimize fraud in the company so that the company's financial performance is getting better. The audit committee and the board of directors have no significant effect on the company's financial performance. This shows that the size or size of the audit committee does not guarantee the effectiveness of the audit committee's performance in supervising the company's financial performance, and the size of the board of directors does not guarantee the effectiveness of carrying out its responsibilities in managing the company.

Penelitian ini dilakukan untuk mengkaji pengaruh kurs Rp/USD dan tingkat diskonto terhadap penanaman modal asing di Indonesia.  Untuk mencapai tujuan tersebut  maka dilakukan pengumpulan data sekunder, dilanjutkan dengan  mengolah data untuk memformulasi model  regresi linier berganda. Uji hipotesis  dilakukan dengan uji t  untuk menguji secara parsial  pengaruh kurs Rp/USD dan tingkat diskonto  terhadap penanaman modal asing di Indonesia, dan uji F untuk menguji pengaruh secara simultan  kurs Rp/USD dan tingkat diskonto terhadap penanaman modal asing di Indonesia, dengan tingkat kepercayaan 95 persen.  Hasil uji hipotesis ditemukan bahwa secara parsial hanya kurs Rp/USD berpengaruh signifikan terhadap penanaman modal asing di Indonesia dengan koefisien regresi sebasar 3,89 artinya  apabila harga USD mengalami apresiasi sebesar 1 persen terhadap Rupiah, maka  penanaman modal asing untuk investasi riil meningkat sebesar 3,89 persen;  sedangkan tingkat diskonto tidak berpengaruh signifikan terhadap penanaman modal asing.  Temuan selanjutnya adalah secara bersama-sama  kurs Rp/USD dan tingkat diskonto  berpengaruh signifikan terhadap  penanaman modal asing di Indonesia, sehingga model regresi berganda penanaman modal asing  adalah  Y = 8,82 + 3,89x1 – 0,44x2; Y  adalah penanaman  modal asing, X 1 adalah kurs Rp/USD dan X2 adalah tingkat diskonto.

Besides the university departments of education and their affiliated colleges, government and government aided institutions; private and self-financing colleges and open universities are also engaged in teacher education. Though most teacher education programmes are nearly identical yet their standards vary across institutions and universities. However, teacher education curriculum across the country has been blamed for ineptitude and needs urgent reforms. Teacher educators are a pivotal point of this programme and their opinion regarding the curriculum is very important. Keeping the above in mind, the present study aimed to find out the attitude of teacher educators towards existing teacher education curriculum and the needed renewal in teacher education curriculum. Data was collected from randomly selected 107 teacher educators working in colleges of education affiliated to GGSIPU and M.D.U. A five point attitude scale was developed by the researchers for the purpose of ascertaining their attitude. The findings revealed that teacher educators are largely in disagreement with the current curriculum and hold that a new vision needs to be made for the education of teachers as per the present needs of globalisation, RTE norms, and adoption of inclusive education.
