Energia e meio ambiente no Brasil

Energy production and use present environmental impacts, but the present consumption patterns can be improved through a more efficient use of energy and a shift from fossil fuels to renewable sources of energy. Due to hydroelectricity and bioethanol, Brazil still has a comfortable position compared to the rest of the world. Self-sufficient in oil, the country today discusses how to supply natural gas and electricity in the medium and long terms, with different positions about the path to follow. The present article proposes recommendations, with special focus on the electricity sector.
Implementing Change in Public Organisations: The Effects of Motivation to Transfer as a Mediating Factor in the Relationship between Supervisory Leadership and Knowledge Transfer

Supervisory leadership is essential in the management performance and human resource development chain. Besides supervisory leadership, motivation to transfer is emphasised as another crucial factor affecting knowledge transfer. This study aims to investigate a significant relationship between the independent variable (supervisory leadership), mediating variable (motivation to transfer) and dependent variable (knowledge transfer). A cross-sectional research design is used to gather 540 surveys from workforces in Malaysian public departments. The structural equation modelling using SmartPLS findings confirmed that the relationship between supervisory leadership and knowledge transfer is mediated by a motivation to transfer. Future research should include both public and private enterprises to increase the effectiveness of the study’s conceptual framework in the organisational context.

Dietary Patterns Are Associated with the Gut Microbiome and Metabolic Syndrome in Mexican Postmenopausal Women

Postmenopausal women are at an increased risk of developing metabolic syndrome (MetS) due to hormonal changes and lifestyle factors. Gut microbiota (GM) have been linked to the development of MetS, and they are influenced by dietary habits. However, the interactions between dietary patterns (DP) and the GM of postmenopausal women, as well as their influence on MetS, still need to be understood. The present study evaluated the DP and microbiota composition of postmenopausal Mexican women with MetS and those in a control group. Diet was assessed using a food frequency questionnaire, and the GM were profiled using 16S rRNA gene sequencing. Greater adherence to a “healthy” DP was significantly associated with lower values of MetS risk factors. GM diversity was diminished in women with MetS, and it was negatively influenced by an “unhealthy” DP. Moreover, a higher intake of fats and proteins, as well as lower amounts of carbohydrates, showed a reduction in some of the short-chain fatty acid-producing genera in women with MetS, as well as increases in some harmful bacteria. Furthermore, Roseburia abundance was positively associated with dietary fat and waist circumference, which may explain 7.5% of the relationship between this macronutrient and MetS risk factors. These findings suggest that GM and diet interactions are important in the development of MetS in postmenopausal Mexican women.
The Problems of Panoptic Invigilation Programs as Evidence of Cheating

Abstract The demand for online invigilation programs had dramatically increased due to the expansion of online learning; however, demand was further galvanized by the COVID-19 pandemic. Unfortunately, there are many technical and ethical problems with these programs that cannot be easily mitigated. Notably, they are beset by several inherent racial, gender, neuro-normative, and socio-economic biases, which means that people of color, women, neuro-divergent, and less affluent students will be more likely to be accused of cheating. While these issues have received increasing attention, a minimal amount of focus has been given to the legitimacy of these programs’ key indicator of academic malfeasance: ocular motility. The reliance upon eye movements to identify potential academic dishonesty is problematic because ocular motility is fundamental to cognitive processes such as information recall and creative thought. Given that the consequences of finding a student in violation of honor code strictures can have devastating impacts on a student’s career and given that these impacts do not affect all students equally, institutions and instructors that have adopted these panoptic surveillance programs should heavily consider the limitations of these programs, the dangerous biases that are built into them and their deployment, and the cascade of inequitable outcomes they may help propagate.
Modeling and energy recovery from a system with two pseudo-levitating magnets

In this paper, a model of an electromagnetic system with two levitating magnets is presented. Modeling was performed using the results of experiments. The data obtained make it possible to ﬁt the magnetic forces between two magnets using a 5 th order polynomial. The time series show that dry friction constitutes an important part of damping forces. The differential equations of motion consider strong nonlinearities of magnetic and damping forces. These terms cause the nonlinear hardening effect. The energy recovered by magnetic induction is dissipated in the resistors. Numerical simulations show that resistance has an impact on magnet dynamics and energy recovery. From the resonance characteristics obtained, optimal resistance is determined when energy recovery is the highest.
Controlled‐source electromagnetic monitoring of reservoir oil saturation using a novel borehole‐to‐surface configuration

To advance and optimize secondary and tertiary oil recovery techniques, it is essential to know the areal propagation and distribution of the injected fluids in the subsurface. We investigate the applicability of controlled‐source electromagnetic methods to monitor fluid movements in a German oilfield (Bockstedt, onshore Northwest Germany) as injected brines (highly saline formation water) have much lower electrical resistivity than the oil within the reservoir. The main focus of this study is on controlled‐source electromagnetic simulations to test the sensitivity of various source–receiver configurations. The background model for the simulations is based on two‐dimensional inversion of magnetotelluric data gathered across the oil field and calibrated with resistivity logs. Three‐dimensional modelling results suggest that controlled‐source electromagnetic methods are sensitive to resistivity changes at reservoir depths, but the effect is difficult to resolve with surface measurements only. Resolution increases significantly if sensors or transmitters can be placed in observation wells closer to the reservoir. In particular, observation of the vertical electric field component in shallow boreholes and/or use of source configurations consisting of combinations of vertical and horizontal dipoles are promising. Preliminary results from a borehole‐to‐surface controlled‐source electromagnetic field survey carried out in spring 2014 are in good agreement with the modelling studies.
Preconception Immunoglobulins and Complements as Potential Biomarkers in Unexplained Female Infertility in Saudi Arabia

Background: Immunological abnormalities are currently under investigation to potentially unravel the etiology of frustrating cases of unexplained female infertility (UFI). Objectives: To explore the prevalence of immunological abnormalities in the levels of total immunoglobulins and complements in the cases of UFI. Methods: Females with a history of UFI were included in this cross-sectional study. They were consulted at the clinical immunology clinic at the King Abdulaziz University Hospital (KAUH). Their demographics, clinical features, total immunoglobulins, and complement test results were collected and analyzed for any relationship with UFI. Results: One hundred and twenty-one cases of UFI with an average age of 34 ± 5.6 (range from 23 to 49 years old) were studied. Secondary infertility was predominant in 99 cases (81.8%). An overall prevalence of at least one abnormal level of total immunoglobulins or complements was found in 65 cases (55.1%). The predominant immunological abnormalities were elevated levels of immunoglobulins (hypergammaglobulinemia) in 51 cases (43.2%), high IgG in 26 cases (22%), high IgA in 14 cases (11.9%), and high IgM in 11 cases (9.3%). This was followed by elevated levels of complements (hypercomplementemia) in C4 in nine cases (8.5%). A significant association was found between the high C4 group and some parameters of infertility, including primary infertility (p = 0.005), no pregnancy (p = 0.001), and no abortion (p = 0.047), in comparison to that of the normal C4 group. Moreover, a statistically significant association was found between the high IgA group and abortion in comparison to the normal IgA group (p = 0.054). Conclusion: At least one abnormal level of total immunoglobulins or complements was detected in more than half of the UFI cases. The commonest abnormalities were hypergammaglobulinemia (IgG, IgM, IgA) and hypocomplementenemia (C4), which showed a potential association with some infertility parameters. These findings may encourage the screening of general immunological tests to explore promising new immunopathology in UFI.
Classification of seismic patterns in a hierarchical model of rupture: a new phase diagram for seismicity

SUMMARY I present a detailed description of the temporal properties of seismicity in a hierarchical model of rupture incorporating healing and faulting. At the microscopic scale, a stochastic process controls transitions between a solid and a broken state with respect to the local stress. From the distribution of broken elements, geometric rules of interaction determine the state of fracturing of domains of larger dimensions and the shape of the stress redistribution. Then, any point in space evolves with respect to its state of stress and its state of fracturing measured at different length scales. Applied to a single fault zone under a constant loading rate, this model of seismicity reproduces the main characteristics of the seismic catalogues: Gutenberg‐ Richter law for the magnitude‐frequency relationship, Omori law for the aftershock decay rate, clustering of major events, swarms of earthquakes, seismicity of creeping segment and seismic noise. I infer that the control parameter is the dimensionless parameter A, the ratio between a characteristic time of healing and a characteristic time of loading. Following the magnitude of A, different seismic scenarios emerge: if A ≈ 1, the system is in a critical state and largest events can occur over a wide range of timescales (e.g. clustering of major events); if A 1, the system is in subcritical states controlled by healing and the fault zone may be creeping. One particular feature is that the amplitude of the stress stored in the fault zone decreases and the frequency of large events increases as the critical state is approached. This can be interpreted as a weakening process. I propose a new phase diagram of seismicity to illustrate an alternative to the classical seismic cycle picture.
Survival Outcomes After Double-Lung Transplantation for Refractory Lung-Limited Cancers and Incidence of Post-Transplant Lung Cancer

Background To evaluate the role of double-lung transplantation (DLT) for lung cancer, the survival outcomes of patients who underwent DLT for lung cancer and the incidence of de novo lung cancer after DLT were assessed. Material/Methods Data from all cases reported in the literature were pooled for analysis and additional data were collected from the Organ Procurement Transplantation Network (OPTN) registry. Recurrence-free survival (RFS), overall survival (OS), and cancer-specific survival (CSS) of patients who underwent DLT for lung cancer were determined. Moreover, the incidence of de novo lung cancer and associated OS in lung transplant recipients were examined. Results Of the 20 cases series and 15 cases from the OPTN registry, the 5-year RFS was 55.0% and 66.7% and the 5-year OS was 55.0% and 26.7%, respectively, and the median CSS was 48.0 (range, 2.0–144.0) and 27.7 (range, 0.2–66.6) months, respectively. In the OPTN data, the incidence of post-transplant lung cancer in patients who underwent DLT for the non-cancerous disease was 0.8% and the 5-year OS was 47.3%. Conclusions In conclusion, our integrated analysis of the case series and the OPTN registry demonstrated promising survival outcomes for patients with refractory bilateral lung cancer who underwent DLT. Although there are limitations to consider, the results of this study underscore the potential benefits of DLT in managing refractory lung-limited lung cancer.
Properties of natural saline soils at Resko Przymorskie Lake

A b stra c t: The natural saline soils in the vicinity o f Resko Przymorskie Lake were formed from silted up peat o f lowm oor. The peat land was periodically flooded by sea waters. The total content o f the salt amounted to 3.78 g/dm 3 in ground waters and to 4.58 g/dm 3 in surface waters. The salinity o f waters caused an increased salinity o f soils. The total salt content in the soils was up to 3.11%. In this amount dominated NaCl. In spite o f very high quantity o f salt, the electrical conductivity o f soils never exceeded 12.92 dS/m. It should be connected with the organic character o f these soils. The very high SAR coefficient o f ground and surface waters influenced very intensive penetration o f the Na cations into the sorption com plex o f the soils. The saturation degree o f the sorption com plex with the sodium cations reached 30% CEC. T hese saline soils were classified as sem isolonchak sodium soils.
A nomogram for predicting recurrence in endometrial cancer patients: a population-based analysis

Objective Endometrial cancer recurrence is one of the main factors leading to increased mortality, and there is a lack of predictive models. Our study aimed to establish a nomogram predictive model to predict recurrence in endometrial cancer patients. Method Screen 517 endometrial cancer patients who came to Nanjing Drum Tower Hospital from 2008 to 2018. All these data are listed as the training group, and then 70% and 60% are randomly divided into verification groups 1 and 2. Univariate, Multivariate logistic regression, stepwise regression were used to select variables for nomogram. Nomogram identification and calibration were evaluated by concordance index (c-index), area under receiver operating characteristic curve (AUC) over time and calibration plot Function. By decision curve analysis (DCA), net reclassification index (NRI), integrated discrimination improvement (IDI), we compared and quantified the net benefit of nomogram and ESMO-ESGO-ESTRO model-based prediction of tumor recurrence. Results A nomogram predictive model of endometrial cancer recurrence was established with the eight variables screened. The c-index (for the training cohort and for the validation cohort) and the time-dependent AUC showed good discriminative power of the nomogram. Calibration plots showed good agreement between nomogram predictions and actual observations in both the training and validation sets. Conclusions We developed and validated a predictive model of endometrial cancer recurrence to assist clinicians in assessing recurrence in endometrial cancer patients.
Air bubbles and Clathrate hydrates in the transition zone of the NGRIP Deep Ice Core

Field studies of air bubble and clathrate inclusions in the NGRIP ice core reveal two stages of clathrate formation. In the transition zone translucent primary clathrates with rough surfaces and irregular shapes, formed from individual bubbles, split up and form smaller specimens. Deeper down in the transition zone (∼1100m), clathrate metamorphosis sets in, giving rise to the formation of transparent secondary clathrates, with smooth and regular, often polyhedral or faceted shapes. Rod‐like crystals of great length (∼2mm) often show signs of separation into smaller units that fragment into smaller specimens. These findings imply that the simplified picture of one bubble forming one clathrate has to be modified.
Fitness and fatness in children and adolescents: investigating their role in the association between physical activity and cardiometabolic health

To verify the role of the combination of fitness and fatness in the relationship between physical activity (PA) and cardiometabolic risk in children and adolescents. This is a cross-sectional study performed with 2786 children and adolescents (6 to 17 years). Fitness was determined by the cardiorespiratory fitness (CRF) six-minute walking and running test. Waist circumference (WC) was considered a fatness indicator. A selfreported questionnaire was used to determine PA practice, whereas the clustered cardiometabolic risk score (cMetS) was calculated by summing z-scores of triglycerides, total cholesterol/HDL-C ratio, systolic blood pressure, glucose, and WC. Considering the combination of CRF (fitness) and WC (fatness), the following phenotypes were created: Fit/Unfat, Fit/Fat, Unfit/Unfat and Unfit/Fat. Moderation analyses were tested using linear regression models. Significant interactions were found between PA and Unfit/Fat category (β = -0.001; p = 0.001) only for adolescents. The interaction observed in the Unfit/Fat phenotype indicated that adolescents who practise PA for 330 minutes per week presented lower cMetS compared to those who do not practise or practise for 60 minutes respectively. The combination of fitness and fatness moderates the relationship between PA and cardiometabolic risk, suggesting that adolescents, particularly those who are less fit and present high adiposity, should be encouraged to engage in regular PA to improve their metabolic health.
Newly-recognised Continental Fragments Rifted from the West Australian Margin

The southwest Australian margin formed at the nexus of rifting and breakup between India, Australia and Antarctica in the Early Cretaceous. Studying the basin evolution along this margin has been hampered by a lack of data from the offshore Perth Abyssal Plain (PAP), and from the conjugate Greater Indian margin, which was highly deformed during collision with Eurasia. Here, we present new data (magnetic anomaly profile data, swath bathymetry, and dredge samples) constraining the evolution of the PAP, collected during voyage ss2011/v06 of the RV Southern Surveyor in late 2011. The Batavia Knoll (BK) and Gulden Draak Knoll (GDK) are two prominent, previously unsampled bathymetric features located >1600 km offshore Australia that have been assumed to be igneous features. Successful dredges on the western flanks of both knolls recovered continental basement rocks, revealing that both knolls are microcontinents. We use quantitative analysis of shiptrack magnetic profiles combined with satellite gravity anomalies to estimate the extent and spatial variation in thickness of the continental crust. Sediment thickness estimates are made using depths to magnetic sources for shiptrack profiles. The geophysical data provide evidence for basin structures within the knolls of a similar scale to those imaged within other fragments of stretched continental crust such as the Naturaliste Plateau. Interpretation of previously unidentified M-series anomalies in the Perth Abyssal Plain, combined with dredge data, support a reconstruction model where the BK and GDKs are microcontinents that initially rifted with Greater India during breakup with Australia at ~130 Ma. As seafloor spreading ceased in the PAP at about 105–100 Ma, a westward ridge jump led to the rifting of the BK and GDK from Greater India.
Comparative Study of Endoscopic and Conventional Septoturbinoplasty in Patients with Nasal Airway Obstruction

Objectives: The goal of our study was to perform endoscopic septoplasty with or without turbinate reduction and also to determine its postoperative subjective and objective improvements. Methods: This was a hospital-based pre and post clinical trial study of 63 patients with nasal septal deviation treated with endoscopic and conventional septoplasty with or without turbinoplasty from 2013 to 2016. Nasal airway patency was recorded before and 2.7 months after surgical treatment using a visual analogue scale (VAS), Glatzel mirror test and bilateral peak nasal inspiratory flow (PNIF) measure. Results: Endoscopic (27 patients) and conventional septoturbinoplasty (36 patients) was performed on 63 patients (40 males; 23 females) with a mean age of 35 years. The results showed a significant improvement of nasal passage condition in scales of VAS, Glatzel mirror test, and bilateral PNIF values after surgery in both groups. In both surgical techniques septoplasty with turbinate reduction showed better improvement in VAS and bilateral PNIF scores than septoplasty alone. Conclusion: The application of endoscopic technology has an advantage of precise visualization and is a valuable tool especially when it is used for educational reasons. Subjective and objective improvements were confirmed equally in both endoscopic and conventional groups.
Belemnites from the Upper Pliensbachian and the Toarcian (Lower Jurassic) of Tournadous (Causses, France)

Jurassic belemnites represent promising proxies especially for palaeoecological and also palaeobiogeographical reconstructions. However, basic knowledge on taxonomic composition, biostratigraphy and diversity of Early Jurassic belemnites is still dramatically low, especially for France. The present study provides new data on belemnites from the southern part of the Northwest European Province. More than 700 specimens have been collected along the Tournadous section in the Causses Basin (Southern France); they represent ten genera and 30 species belonging to Hastitidae, Megateuthididae, Passaloteuthididae, and Salpingoteuthididae. Furthermore, numerous ammonites have been collected, allowing to establish a standard chronostratigraphical scheme of the studied section and thus to assign, for the first time, a precise chronostratigraphical distribution to the Early Jurassic belemnites of Southern France. The analysis of belemnite diversity and its variations along the section compared to the well-known fauna of the northern part of the Northwest European province (Germany and England) open interesting prospective for belemnites palaeobiogeography.
Global Mapping of Potential and Climatic Plant‐Available Soil Water

The estimation of plant‐available soil water (PASW) is essential to quantify transpiration fluxes, the onset of heatwaves, irrigation water management, land‐use decisions, vegetation ecology, and land surface memory in climate models. PASW is the amount of stored water available for plant use. It is broadly defined as the difference between soil water content at field capacity (FC) and wilting point (WP) in the root zone. The limiting states of FC and WP are linked to gravitational drainage and plant physiology and are often deduced from soil water characteristics at prescribed matric potentials (−3.3 and −150 m for FC and WP, respectively). Evidence suggests that static definition of FC at a constant matric potential ignores dynamic effects on FC attainment affected by soil and climate. Here, we revise the definition of PASW by considering (a) soil‐specific dynamic effects and (b) local climate effects of evaporation and rainfall frequency on PASW. The new global PASW maps benefit from state‐of‐the‐art soil maps, water characteristic parameterization, and incorporation of dynamic definition of FC. For completeness we provide static and dynamic PASW estimates. Globally, ice‐free soils store up to 19,941 km3 of water in the top 1 m (representing 18% of annual terrestrial precipitation). Adjusted for local climatic conditions, global PASW storage rarely exceeds 14,853 km3 per year highlighting the need for multiple refilling of soil profiles. Differences between potential and climatic PASW are manifested primarily in arid regions (where soil profiles are rarely filled to capacity) whereas in humid regions differences in PASW storage are minor.
