New Technique for Reducing and Modeling Nasolabial Fat and Jowls: Lipoestructuración
Authors: FELICIDADE  , Iensen Sidnei , LOPEZ  , Mendoza Coreli Coromoto
Published: April 2023

The aging process is characterized by ptosis of the fatty compartments of the face, loss of subcutaneous volume, weakening of the supporting structures of the face. In this process movement may occur, atrophy of the deep pads and hypertrophy of different superficial fat pads, for unknown causes, leaving the nasolabial fat prominent [3,4]. Currently, facial fat reduction can be performed by liposuction only in the submental and cervical regions [7]. Other minimally invasive treatments such as subcutaneous mesotherapy with deoxycholic acid or sodium deoxycholate associated with other active ingredients are being studied in aesthetic medicine to allow treatment of other areas of the face [2,4,6]. The development of new techniques is promising, such as the subcision of adipose tissue, already used in cellulite, is believed to allow the migration of fat cells in facial compartments to other compartments with lower volume, inducing an increase in adipose tissue in deficient compartments, and increases the stimulation of collagen evidenced in the treatment of acne scars [1,5]. As well as, the lack of standardization of mesotherapy techniques “chemical lipolysis” to reduce fat compartments. This prospective experimental clinical study was performed with 5 female patients. Clinical evidence was sought for the reduction of nasolabial fat compartments with modeling of facial fat and increase of self-esteem of patients with standardization of a new technique called lipostructure. Anthropometric measurements of the treated compartments and satisfaction research questionnaires of these patients will be used, as well as post-procedure follow-up to demonstrate the main adverse effects of this technique. The results found point to a mean reduction of 2.03% in the nasolabial fat of the patients studied (p ≤ 0.05), demonstrating its efficacy. The patient evaluation form 30 days after the procedure showed that 80% of the patients were satisfied (40% well satisfied and 40% very satisfied), demonstrating its efficiency

Introduction: The Richards equation or a simplification, such as the Green and Ampt equation, is mainly used to describe the flow of water in the soil. The Richards equation produces accurate results, but lacks general analytical solutions, so the Green and Ampt equation is used as an intermediate way of modeling the phenomenon by maintaining physical-mathematical bases in the representation.Objective: To optimize the parameters of saturated hydraulic conductivity and wetting front suction of the Green and Ampt equation by means of a nonlinear optimization algorithm, and to validate the solution to optimize the parameters as a function of soil textures.Methodology: The Levenberg-Marquardt algorithm was used to estimate the infiltration parameters of the Green and Ampt equation, and the initial pair of values was taken according to soil texture.Results: This model was used to calculate the hydraulic conductivity parameters at saturation and wetting front suction.Study limitations: A homogeneous soil column and a constant initial moisture content were considered for the whole column.Originality: The optimization algorithm was oriented to keep the parameter values within the range established in the textural classes.Conclusions: An optimization algorithm was implemented to estimate the parameters Ksand hfby solving the Green and Ampt equation, which included code performance review and experimental validation with infiltration tests.

Introduction: The Sonoran desert shows degradation, risk of desertification and loss of biodiversity. A typical plant of the area is the Mexican ironwood (Olneya tesota), with ecological, economic and social importance.Objectives: To evaluate germination, survival and growth of Mexican ironwood seeds sown in degraded soil, conserved soil, agricultural soil and nursery in Hermosillo, Sonora, Mexico.Methodology: Annual experiments were carried out from 2017 to 2019, with 1 450 Mexican ironwood seeds sown directly in degraded and conserved arid soils, and in soil patches (bare, with grasses, undertree, in accumulation zones and with herbivory protections). The experiment was conducted under controlled conditions of humidity, nursery and irrigated agricultural soil.Results: Seed germination was 0 to 20 % in degraded soils, with zero annual survival. The application of irrigation and herbivory protection led higher germination (16 to 78 %) and annual survival (0 to 50 %). Annual survival in patches of conserved soil ranged from 0 to 30. The highest germination (84 %), annual survival (74 %) and annual growth (84.7 cm) were observed in agricultural soil and drip irrigation.Limitations of the study: The results correspond to three years of evaluations.Originality: There are no detailed studies on the limitations of establishing ironwood plants.Conclusions: Netting protection increases germination, survival and height of ironwood plants in degraded soils. It is possible to initiate ironwood forest plantations on agricultural land with drip irrigation.
Ukraine at War: Resilience and Normative Agency
Authors: Kurnyshova Yulia
Published: April 2023

Russia’s full-scale invasion of Ukraine in February 2022 has transformed all aspects of life in the country, including societal attitudes, national politics and Ukraine’s agency on the international arena. The article seeks to discuss and conceptualise how practices of resilience create discursive spaces for producing and shaping Ukraine’s agency. In other words, how do experiences of resilience in four different spheres (societal, institutional, communicative and subregional) affect Ukraine’s capacity not only to cope with the intervention and survive as a nation, but also to contribute to the future of international security order. The author argues that by containing the Russian army, Ukraine can be viewed as a co-producer of European security, which is particularly acknowledged by European countries bordering on Russia. Ukraine’s agency, as unfolded in 2022, addresses Western countries with an insistent demand to perceive Ukraine as a part of the European normative order.

Apresenta-se um estudo de risco de incêndio e de explosão proveniente de poeira de açúcar em armazéns. Pelos dados analisados, é possível determinar que o açúcar é um sólido combustível que, quando ignizado, pode promover explosão em locais confinados ou entrar em combustão. Os resultados demonstram que é possível observar que os resultados obtidos das amostras analisadas variam de acordo com o tamanho da sua partícula misturada com o ar, mas seu comportamento é uniforme em relação a determinação de sua ignitabilidade. A existência de pós ou poeiras é inerente ao processo destes locais de armazenamento, sendo esses passíveis de explosão. Portanto afastar os armazéns das áreas limítrofes do terreno, ou instalar barreiras físicas para proteção dos moradores da vizinhança, é necessário e emergencial, inclusive deveria ser uma política pública. Por fim, constata-se que são necessárias medidas que proporcionem detalhamentos para a implementação de proteção contra incêndios de sólidos combustíveis particulados e de seus perímetros de segurança para diferentes pressões envolvidas, a fim de garantir segurança à população lindeira a armazéns.

Abstract. Accurate quantification of long-term trends in stratospheric ozone can be challenging due to their sensitivity to natural variability, the quality of the observational datasets, non-linear changes in forcing processes as well as the statistical methodologies. Multivariate linear regression (MLR) is the most commonly used tool for ozone trend analysis, however, the complex coupling in most atmospheric processes can make it prone to the over-fitting or multi-collinearity-related issues when using the conventional Ordinary Least Squares (OLS) setting. To overcome this issue, we adopt a regularised (Ridge) regression method to estimate ozone trends and quantify the influence of individual processes. Here, we use the Stratospheric Water and OzOne Satellite Homogenized (SWOOSH) merged data set (v2.7) to derive stratospheric ozone profile trends for the period 1984–2020. Beside SWOOSH, we also analyse a machine-learning-based satellite-corrected gap-free global stratospheric ozone profile dataset from a chemical transport model (ML-TOMCAT), and output from two chemical transport model (TOMCAT) simulations forced with ECMWF reanalyses ERA-Interim and ERA5. With Ridge regression, the stratospheric ozone profile trends from SWOOSH data show smaller declines during 1984–1997 compared to OLS with the largest differences in the lowermost stratosphere (> 4 % per decade at 100 hPa). Upper stratospheric ozone has increased since 1998 with maximum (~2 % per decade near 2 hPa) in local winter for mid-latitudes. Negative trends with large uncertainties are observed in the lower stratosphere with the most pronounced in the tropics. The largest differences in post-1998 trend estimates between OLS and Ridge regression methods appear in the tropical lower stratosphere (with ~7 % per decade difference at 100 hPa). Ozone variations associated with natural processes such as the quasi-biennial oscillation (QBO), the solar variability, the El Niño–Southern Oscillation (ENSO), the Arctic oscillation (AO) and the Antarctic oscillation (AAO) also indicate that Ridge regression coefficients are somewhat smaller and less variable compared to the OLS-based estimates. Additionally, ML-TOMCAT based trend estimates are consistent with SWOOSH data set. Finally, we argue that the large differences between the satellite-based data and model simulations confirm that there are still large uncertainties in ozone trend estimates especially in the lower stratosphere, and caution is needed when discussing results if explanatory variables used are correlated.

Abstract. Atmospheric Gravity Waves and Traveling Ionospheric Disturbances can be observed in the neutral atmosphere and the ionosphere at a wide range of spatial and temporal scales. Especially at medium scales, these oscillations are often not resolved in general circulation models and are parameterized. We show that ionospheric disturbances forced by upward propagating atmospheric gravity waves can be simultaneously observed with the EISCAT Very High Frequency incoherent scatter radar and the Nordic Meteor Radar Cluster. From combined multi-static measurements, both vertical and horizontal wave parameters can be determined by applying a specially developed Fourier filter analysis method. This method is demonstrated using the example of a strongly pronounced wave mode that occurred during the EISCAT experiment on 7 July 2020. Leveraging the developed technique, we show that the wave characteristics of Traveling Ionospheric Disturbances are notably impacted by the fall transition of the mesosphere/lower thermosphere. We also demonstrate the application of using the determined wave parameters to infer the thermospheric neutral wind velocities. Applying the dissipative anelastic gravity wave dispersion relation, we obtain vertical wind profiles in the lower thermosphere.
Modeling atmosphere-land interactions at a rainforest site – a case study using Amazon Tall Tower Observatory (ATTO) measurements and reanalyis data

Published: April 2023

Abstract. Modeling the interactions between atmosphere and soil at a forest site remains a challenging task. Using tower measurements from the Amazon Tall Tower Observatory (ATTO) in the rainforest, we evaluated the performance of the land model JSBACH focusing especially on processes influenced by the forest canopy. As a first step, we analyzed whether ERA5 and MERRA-2 reanalysis data are suitable to be used as land model forcing. Comparing five years of ATTO measurements to near-surface reanalysis data, we found a substantial underestimation of wind speeds by about 1 m s−1. ERA5 captures monthly mean temperatures quite well but overestimates annual mean precipitation by 30 %. Contrarily, MERRA-2 overestimates monthly mean temperatures in the dry season (August–October) by more than 1 K, while mean precipitation biases are small. To test how much the choice of reanalysis data set and the reanalysis biases affect the results of the land model we performed spin-up and model runs using either ERA5 or MERRA-2 and with and without a bias correction for precipitation and wind speed and compared the results. The choice of reanalysis data set results in large differences of up to 1.3 K for soil temperatures and 20 % for soil water content, which are non-negligible especially in the first weeks after spin-up. Correcting wind speed and precipitation biases also notably changes the land model results – especially in the dry season. Based on these results, we constructed an optimized forcing data set using bias-corrected ERA5 data for the spin-up period and ATTO measurements for a model run of two years and comparing the results to observations to identify model shortcomings. Generally, the shape of the soil water profile is not reproduced correctly, which might be related to a lack of vertical variability of soil properties or of the root density. The model also shows a positive soil temperature bias and overestimates the penetration depth of the diurnal cycle. This problem could possibly be addressed by including a separate canopy layer into the model to improve the processes related to storage and vertical transport of energy within the model.
A quantitative assessment of air-sea heat flux trends from ERA5 since 1950 in the North Atlantic basin
Authors: Mayer Johannes , Haimberger Leopold , Mayer Michael
Published: April 2023

Abstract. This work aims to investigate the temporal stability and reliability of trends in air-sea heat fluxes from ERA5 forecasts over the North Atlantic basin for the period 1950–2019. Driving forces of the trends are investigated using analyzed state quantities from ERA5. Estimating trends from reanalysis data can be challenging as changes in the observing system may introduce temporal inconsistencies. To this end, the impact of analysis increments is discussed. For individual sub-regions in the North Atlantic basin, parametrization formulas for latent and sensible heat fluxes are linearized to quantitatively attribute trends to long-term changes in wind speed, moisture, and temperature. Our results suggest good temporal stability and reliability of air-sea heat fluxes from ERA5 forecasts on sub-basin scale and below. Regional averages show that trends are largely driven by changes in the skin temperature and atmospheric advection (e.g., of warmer or drier air masses). The influence of climate variability modes, such as the North Atlantic Oscillation (NAO) and Atlantic Multidecadal Oscillation on the found patterns is discussed as well. Results indicate a significant impact on trends in the Irminger and Labrador Sea associated with more positive NAO phases during the past 4 decades. Finally, we use basin-wide trends of air-sea heat fluxes in combination with an observational ocean heat content estimate to provide an energy-budget-based trend estimate of the Atlantic meridional overturning circulation (AMOC). A decrease of area-averaged air-sea heat fluxes in the North Atlantic basin suggests a decline of the AMOC over the study period. However, basin-wide flux trends are deemed partially artificial, as indicated by temporally varying moisture increments. Thus, the exact magnitude of change is uncertain, but its sign appears robust and adds complementary evidence that the AMOC has weakened over the past 70 years.

Abstract. Rainfall is the main driver of runoff generation and soil erosion. The impacts of natural rainfall on water erosion have been extensively studied at an inter-event scale; however, very few studies have explored the intra-event influences and associated responses to different surface cover types. In this study, long-term in situ field observations of surface runoff, subsurface flow, and soil loss characteristics in three surface cover plots (bare land, litter and grass cover) under natural rainfall events were conducted from 2002 to 2012 in the red soil hilly region of southern China. According to the period of most concentrated rainfall, 262 rainfall events were classified into four types of intra-event variation: advanced, intermediate, delayed, and uniform patterns. For bare land, the advanced pattern with the shortest duration and the highest intensity was main rainfall type for surface runoff and soil loss; the contribution rates were 57.24 % and 75.17 % for surface runoff and soil loss, respectively. Sediment yields were more sensitive to intra-event rainfall variation than surface runoff. The highest subsurface flow was found in the delayed pattern with the longest duration and high depth, followed by the uniform, intermediate, and advanced patterns. For all rainfall patterns, compared to the bare land, surface cover significantly reduced surface runoff and soil erosion by 88.01 to 91.69 % and by 97.80 to 97.95 %, respectively, while subsurface flow was increased from 3.55 to 5.92 times. The reduction benefits of litter cover were comparable to those of grass cover. However, the increasing benefit of subsurface flow for litter cover for each rainfall pattern ranged from 1.38 to 2.67 times those of grass cover. Moreover, surface cover weakened the influences of intra-event rainfall variation on surface-subsurface flow and soil loss. The results demonstrated that intra-event rainfall variation had important effects on surface-subsurface flow and soil loss, and provided a basis for optimizing surface cover measures to effectively respond to extreme water erosion and drought caused by global climate change.

Published: April 2023

El sistema educativo español se encuentra inmerso en período de cambio que se inició hace años y que está orientado hacia una educación que garantice la equidad y la inclusión. Ofrecer a cada alumno y alumna lo que demandan sus características propias e individuales se ha instaurado como el principio rector de la educación del siglo 21 tras la reciente implantación de la ley LOMLOE. Sin embargo, la atención educativa al alumnado con necesidades educativas específicas es diversa y algunas modalidades de escolarización se alejan de este principio. En lo concerniente al alumnado con Trastorno del Espectro Autista (TEA) en la Comunidad Autónoma de Aragón coexisten diversas modalidades escolares: centros ordinarios, centros de educación especial y centros de atención preferente. Con el objetivo de conocer el estado actual de la inclusión del alumnado TEA en el sistema educativo aragonés se ha realizado este estudio fundamentado en una metodología cualitativa que analiza y compara, a partir de un total de 26 entrevistas, las percepciones y experiencias de 19 docentes con diferentes perfiles profesionales en las distintas modalidades escolares y las experiencias de 7 profesionales de la educación dedicados a la gestión, formación del profesorado y jefatura de programas. Los resultados más relevantes dejan entrever actitudes, experiencias y percepciones manifiestamente distintas por parte del profesorado ante la inclusión del alumnado con TEA en función del entorno escolar en el que desempeñan su labor profesional. El hallazgo más relevante alude a la necesidad de una restructuración general del sistema educativo a nivel organizativo y metodológico, así como la ampliación y actualización de la formación en inclusión para todo el profesorado independientemente de su especialidad.

Published: April 2023

The fact cannot be denied that how a single reality that is the supremacy of America, still continues its pace over the world.  Also, American ideals are vastly universal and vaguely used in the political discourses to legitimize its political mission. Qualitative mode of inquiry has been employed to assess the speech and for this, Speech Act theory of Austin (1962) and Searle (1969) has been used as a framework. The tabular presentation of the speech analysis has shown the relative percentages and frequencies of the speech acts employed by the U.S Ambassadress. The result is quite interesting to note that only three speech acts namely expressive, assertive and commissive have been employed by the U.S Ambassadress in her political discourse in order to manipulate the audience. Further, this study exhibits that as always American ideals that is American Dream and American Exceptionalism are propagated through the political discourse and implanted covertly in people’s mind to win their consensus so they accept Jerusalem as Israel’s capital city.

Assessing Programme Strategies in Managing Child Stunting at the Health Facility Level in Matelile Community Council
Authors: Fosa Mpati Evelyn
Published: April 2023

Stunting is an important indicator for child growth and health facilities have played a pivotal role in contributing to the overall reduction in stunting rates. This qualitative study aimed at understanding interventions employed by health facilities to reduce under 5s stunting. Health facilities have reported an increase in stunting in Matelile Community Council. Although the study revealed available health strategies including nutrition education, health promotion and breastfeeding programs to curb the disproportionate rates of stunting, the challenges facing the implementation of such programmes included lack of funding and failure for caretakers to cooperate. The study recommended therefore that, increasing funding into nutrition related programs and training appropriate health personnel on stuntedness could go a long way to reduce stunting in under 5s.

Objective: To determine the diagnostic accuracy of elevated C reactive protein (CRP) and ferritin in predicting severe Covid-19 infection using the World Health Organization’s (WHO) Covid-19 severity classification as gold standard. Study Design: Descriptive study. Place and Duration of Study: This study was conducted at the Pak Emirates Military Hospital, Rawalpindi, from January 1st 2021 till April 30th 2021. Ethical review committee’s (ERC) approval was taken and good clinical practice guidelines were followed. Material and Methods: Baseline blood samples were sent to the hospital laboratory for the measurement of C reactive protein and ferritin levels. PCR was taken as gold standard for the diagnosis of Corona virus disease. Patients were classified into severe and non-severe categories using WHO classification of severity. Sensitivity, specificity, diagnostic accuracy, negative predictive value and positive predictive value were calculated for elevated CRP and ferritin. Results: There were 65 (57.5%) patients who had severe Covid-19 disease and 48 (42.5%) patients who had non-severe Covid-19 disease. Among the patients with severe Covid-19, 57 (87.7%) had elevated CRP levels, and 50 (76.9%) patients had elevated ferritin levels. Testing ferritin levels, against the severity of Covid-19 patients, there was a sensitivity of 76.9%, specificity of 79.2%, positive predictive value (PPV) of 83.3%, negative predictive value (NPV) of 71.7% and diagnostic accuracy of 77.8%. Testing CRP levels, there was a sensitivity of 87.7%, specificity of 85.4%, PPV of 89.1%, NPV of 83.6% and diagnostic accuracy of 86.7%. Conclusion: The results from our study show that CRP has a slightly improved diagnostic accuracy as compared to ferritin. However, both these markers have value in the prediction of severity of Covid-19 infection. Keywords: Covid-19, elevated C reactive protein and ferritin.

Objective: To determine the frequency of elevated serum ferritin levels in gestational diabetes mellitus (GDM) at a tertiary care hospital. Material and methods: This cross sectional study was carried out from 10th July 2017 to 10th January 2018 at “Department of Obstetrics & Gynaecology, Shaikh Zayed Hospital, Rahim Yar Khan”. The sample included 114pregnant women with gestational diabetes mellitus both primi- and multi-gravida . Patients with known diabetics and hypertensives, patients with history of heart diseases and malignancies like breast cancer and brain tumor, severely anemic ladies were excluded.Routine investigations like FBS and serum ferritin levels were done. age, FBS, serum ferritin levels, gestational age, obesity, residential status and family history of GDM was recorded. Results: In present study, age range was 20-40 years and mean age of 30.535±4.29 years, mean gestational age 29.228±2.95 weeks, mean BMI 26.359±1.93 kg/m2, mean Baseline FBS 124.780±6.14 mg/dl and mean Serum ferritin level was 18.122±4.57 ng/ml.

Helicobacter pylori is a widespread pathogen that significantly contributes to dyspeptic disease and gastric cancer. There are conflicting prevalence patterns of H. pylori in HIV-1-infected patients. Although the interaction between HIV and H. pylori infection is not well investigated, previous studies have suggested a decreased prevalence of H. pylori and the limited effectiveness of eradication treatment in HIV-positive individuals. Therefore, this study aimed to describe the serological prevalence of HIV/HSV, HIV/Syphilis, and HIV/H. pylori co-infection among HIV-infected individuals receiving care in a secondary healthcare facility in Port Harcourt, Nigeria. In the study, 100 HIV-infected individuals were screened for HSV, syphilis and H. pylori co-infections. Co-infections were 0.0% for HIV/HSV, 0.0% for HIV/Syphilis and 58.0% for HIV/Helicobacter pylori. Higher prevalence of HIV/H. pylori co-infection occurred among the age group <20-40 (59.5%), males (59.5%), unemployed (100.0%), Ahaoda, Eleme and Etche LGAs, and high CD4 counts of 200-349 and >350 cells/µl (58.3%) compared to other categories. This study confirmed the absence of HSV and syphilis among these participants. It further indicated that co-infection of HIV/H. pylori were high (58.0%), although the underlying mechanisms remained unknown. However, the H. pylori co-infection in HIV-infected individuals was associated (P>0.05) with CD4+ cell counts and any socio-demographic variables evaluated. However, more studies are needed on these patients in Rivers State, Nigeria, to evaluate the infection rate further.

The majority of clinical geneticists in Chile work in the Metropolitan Region (78%). To expand the area of Telemedicine and support the management of the Ministry of Health, we present this Telegenetics development project that includes innovation of assistance and educational nature directed to regions. The implementation of the National Registry of Congenital Anomalies in Chile (RENACH) in the public and private systems, in December 2015, and the obligation to record and describe the anomalies in all newborns, constitutes a favorable scenario that would benefit from the support of clinical geneticists. This proposal brings together a team of 18 specialists and 6 fellows, professionals from different Universities and / or Hospitals of Health Services, in a collaborative project in the area of clinical genetics, which, supported by the HCUCH + CIMT Telemedicine project, will contribute to two regions of Chile better tools for the diagnosis and comprehensive management of newborn patients with congenital anomalies. It can serve as a pilot for a new way to support the registration of malformations throughout Chile and teach clinical genetics concepts. The expected benefits are to improve the quality of care and health management in patients with little-known diseases.
