Abstract: En | Text: En | PDF: En

Classic depictions of human evolutionary ecology cast Homo as predator and other hominins, including Paranthropus robustus, as prey. Such hypotheses rest on a small number of fossils that exhibit evidence of carnivore predation, including the iconic SK 54 cranium from Swartkrans in South Africa. Here we demonstrate that the SK 54 cranium shares its closest affinities with H. erectus sensu lato rather than P. robustus. Demonstrating that Homo was prey for leopards at Swartkrans weakens the historically significant hypothesis that Homo was better able to avoid predation because of being behaviourally and technologically advanced compared to Paranthropus. Subsequent ideas about hominin palaeobiology derived from this hypothesis warrant reconsideration. SIGNIFICANCE: • The small sample of early Homo from southern Africa is increased by the allocation of the SK 54 cranium to that genus. • Evidence from Swartkrans suggests that Homo was prey for leopards. • Hypotheses concerning the biology, behaviour, and technological capabilities of Homo and P. robustus stemming from Brain's seminal work, The Hunters or the Hunted?, should be reassessed.

Abstract We present the case of a patient with venous throm boembolic disease and contraindication to anticoagu lation, where the incidental finding of a duplication of the inferior vena cava was made. This observation determined the need to implant two embolic protection filters. Although this vascular anomaly is rarely present, it is important to keep this possibility in mind to ensure that proper protection is provided when inferior vena cava filters are implanted.

Resumen Se presenta el caso de un paciente con enferme dad tromboembólica venosa y contraindicación de anticoagulación en el cual se halló incidentalmente una duplicación de vena cava inferior, situación que determinó la necesidad del implante de dos filtros de protección embólica. Si bien esta anomalía vascular es de escasa presentación, es importante tener presente esta posibilidad para asegurarse de brindar una co rrecta protección a la hora del implante de filtros de vena cava inferior.

SIGNIFICANCE: We write this Commentary as a reply to Singh et al.(S Afr J Sci. 118(3/4), Art. #13420). We found that Singh et al.'s article did not adequately cover a rounded viewpoint on the topic, and we highlight a different perspective, calling for a balanced review in this regard. We base our argument on two premises. First, the literature study is incomplete, which creates a misleading perception that nothing is currently being done in South Africa to transition to a low carbon economy. Second, we comment on the statements made on seismic surveys. Herewith, we request that the authors consider a corrigendum that better reflects this research space, and call for more discussion on this topic.

Abstract: En | Text: En | PDF: En

BACKGROUND: The current coronavirus disease 2019 (COVID-19) pandemic has stressed why a change towards resilient, robust and sustainable supply chains is more imperative than ever. This is especially true for supply chains of perishable foods, where issues such as the bullwhip effect cause not only economic but also environmental damage. OBJECTIVES: The key objectives of this study are to gain a deeper insight into correlations regarding the causes of the bullwhip effect and to see how a sinusoidal stimulus is affecting the generation of food waste. METHOD: A simplified beef food chain was modelled in Tecnomatix Plant Simulation®. As the bullwhip effect consists of a simplified parameterisation of an excitation duration (period length) and its height (amplitude), these two variables were used to generate a sinusoidal stimulus. The simulation results were statistically verified and checked for commonalities and differences with the already established scientific knowledge. RESULTS: While the expected higher sensitivity of the front links of the supply chain to waste generation can be confirmed, the results of a long stimulation period suggest that the negative effects of the bullwhip effect do not increase indefinitely. CONCLUSION: The analysis of the results has shown that previous theories can be transferred, but that the variation of the variables entails new insights for the interdependencies of the amplitude and period length and their influence on the output variable waste. CONTRIBUTION: The study contributes to a more holistic understanding of the bullwhip effect and, in particular, its implications within a perishable food supply chain.

Abstract: En | Text: En | PDF: En

ABSTRACT Background: The productivity of the coastal Zululand region, which was known as the South African breadbasket for fibre is declining. Climate-related changes are a significant factor contributing to this decline. The 3PG (Physiological Processes Predicting Growth) model was calibrated for E. grandis x E. urophylla hybrids planted in this region to quantify the effect of climate variation x site on their growth and survival. Monthly weather data for the ungauged plantations were estimated using the Random Forest (RF) supervised learning algorithm. A dataset consisting of 17 permanent sample plots (PSPs) and published parameter values for this hybrid in various regions of Brazil were utilized for parameter estimation. Using a parsimonious optimization approach, we developed a novel method called extended Root Mean Square Error (eRMSE) to select the optimal parameter set. Result: The new parameter set yielded accurate predictions for three key variables; quadratic stem diameter (R2 = 0.85, E = 0.73), mean height (R2 = 0.84, E = 0.78), and basal area (R2 = 0.87, E = 0.78). Model performance at 15 independent sites allowed the comparison with three other Brazilian parameter sets for stand volume prediction at a specific age. The optimized parameter set provided a satisfactory, albeit slightly overestimated stand volume (V (m3ha-1), R2 = 0.65, E = -0.32) at the validation sites. Conclusion: The 3PG model can be adapted with parameter set from another region to characterize the growth of E.grandis x E.urophylla stands in South Africa.

Resumen La región de Tacna, Perú, caracterizada por su hiperaridez, se encuentra ubicada en la cabecera del desierto de Atacama, donde la agricultura es uno de los principales sectores económicos y el cambio climático causa grandes impactos, especialmente sobre la sostenibilidad del cultivo de olivo reflejada en la baja producción de aceituna. En este trabajo buscamos identificar la sostenibilidad del cultivo de olivo en la región de Tacna, basada en un enfoque climatológico, correlacionando la producción del cultivo con el fenómeno El Niño-Oscilación del Sur (ENOS). La sostenibilidad del cultivo está directamente relacionada con el clima, siendo la temperatura el factor principal, con amplitud de tolerancia térmica de -7 °C a 40 °C, amplitud óptima entre 15 °C y 25 °C y amplitud en la región de estudio entre 7 °C y 32 °C, lo que consideramos adecuado según los rangos establecidos, donde se obtienen rendimientos relativamente altos respecto a otras regiones del mundo. Por su lado, el fenómeno ENOS, identificado en los años de baja producción: 1980, 1983, 1992, 1998, 2009, 2015 y 2016, reportó volúmenes de producción que se reducen drásticamente. Un caso muy marcado ocurrió en el año 1998, en el cual la producción nacional (Perú) y regional (Tacna) se redujeron a 1,5 y 1,0 miles de toneladas (t), respectivamente, mientras que los valores máximos corresponden a 190,0 y 148,0 miles de t, respetivamente, para el periodo 1979-2020. Hacia el año 2025, convergen las producciones local y nacional, representando que la local sería el 100% de la nacional.

Abstract The Tacna region, Peru, characterized by its hyper-aridity, is located at the head of the Atacama Desert, where agriculture is one of the main economic sectors and climate change causes great impacts, especially on the sustainability of olive cultivation reflected in low olive production. In this work we seek to identify the sustainability of olive cultivation in the Tacna region, based on a climatological approach, correlating the production of the crop with the El Niño Southern Oscillation (ENSO) phenomenon. The sustainability of the crop is directly related to the climate, with temperature being the main factor, with thermal tolerance amplitude from -7 to 40 °C, optimal amplitude between 15 and 25 °C and amplitude in the study region between 7 and 32 °C, which we consider adequate according to the established ranges, obtaining relatively high yields, compared to other regions of the world. For its part, the ENSO phenomenon, identified in the years of low production 1980, 1983, 1992, 1998, 2009, 2015 and 2016, reported production volumes that are drastically reduced. A very marked case occurred in 1998, in which national (Peru) and regional (Tacna) production fell to 1.5 and 1.0 thousand tons (t), while the maximum values correspond to 190, 0 and 148.0 thousand tons, respectively, for the period 1979 – 2020, respectively. Towards the year 2025, local and national production converge, representing that the local would be 100 % of the national.

RESUMO As mudanças climáticas podem causar alterações drásticas nos ecossistemas lacustres especialmente em razão da elevação da temperatura e das alterações na precipitação, provocando, entre outros fatores, aumento no aporte de nutrientes e, consequentemente, eutrofização. Este trabalho apresenta a estimativa de projeções de vazão e carga de nutrientes (NO3−, PO4–3) afluentes à lagoa Mangueira — grande lagoa rasa subtropical localizada no extremo sul do Brasil. As projeções foram baseadas nos produtos do Quinto Relatório de Avaliação das Mudanças Climáticas (AR5), no Representative Concentration Pathway — RCP 2.6, RCP 4.5 e RCP 8.5. Em cada cenário, foram utilizados produtos de até 39 modelos climáticos globais para a estimativa das projeções das variáveis em dois períodos futuros de 30 anos, centrados em 2030 (próximo) e 2070 (longo). Os resultados mostram como situação mais provável o aumento das vazões, com maior concordância entre os produtos do AR5, quando comparados aos do Quarto Relatório de Avaliação das Mudanças Climáticas (AR4) estimados em trabalho anterior. Nas projeções de cargas de nutrientes também prevalece o padrão de aumento. Os nutrientes analisados apresentam elevação de carga média anual de 9,34% no futuro próximo e no RCP 2.6, enquanto no futuro longo e no RCP 8.5 esse valor se eleva para 22,48%. Medidas mitigadoras deverão ser previstas com o objetivo de reduzir a carga de nutrientes afluentes e manter o bom estado ecológico da lagoa.

ABSTRACT Climate change can cause drastic changes in lake ecosystems, especially due to the increase in temperature and changes in precipitation, promoting, among other factors, an increase in the nutrients input and, therefore, eutrophication. This paper estimated the projected flow and nutrients load (NO3−, PO4–3) at the Mangueira lake — a large subtropical shallow lake, located in southern Brazil. The projections were based on the AR5 products for RCP 2.6, RCP 4.5, and RCP 8.5 scenarios. In each scenario, data from as many as 39 global climate models were used to estimate the projected values of flow and nutrients in two 30-year time intervals centered at 2,030 (near future) and 2,070 (long future). Results show the increase in flow is more likely, with a greater agreement between AR5 products when compared to AR4 products estimated in previous work. The pattern of increase also prevails in the projections of nutrient loads. The nutrients analyzed show an average annual load increase of 9.34% in the near future and RCP 2.6 scenario, while in the long future and RCP 8.5 scenario, this value rises to 22.48%. Mitigation measures should be studied to reduce the nutrient inputs and to preserve a good ecological status of the lake.

RESUMEN Spilogale angustifrons cuenta con una amplia distribución en el sureste de México, sin embargo, para la región de Calakmul el conocimiento es escaso. Se reportan nuevos registros de S. angustifrons en la región de Calakmul, Campeche, México. Con un esfuerzo acumulado de 9000 noches-trampa, se obtuvieron 18 fotografías de S. angustifrons que corresponden a 15 eventos independientes, en cuatro estaciones de fototrampeo colocadas en la región de Calakmul. En las estaciones de fototrampeo se registraron cuatro eventos fotográficos en los que se observan a individuos machos, solitarios, pero no fue posible identificar si los registros corresponden a uno o más individuos. Los pocos registros de S. angustifrons en la Península de Yucatán puede deberse a la falta de prospecciones mastozoológicas en la región. Los registros reportados en esta nota, aportan conocimiento sobre la distribución, hábitat, uso de bebederos artificiales y relaciones interespecíficas de S. angustifrons. Al ser un carnívoro es probable que el papel ecológico de S. angustifrons en la región de Calakmul sea relevante, sin embargo los aspectos poblacionales y ecológicos de la especie se desconocen, por lo que es necesario realizar estudios enfocados a conocer el estado de las poblaciones de S. angustifron.

ABSTRACT Spilogale angustifrons has a wide distribution in southeastern Mexico, however, knowledge is scarce for the Calakmul region. New spotted records are reported S. angustifrons in the Calakmul region, Campeche, Mexico. With a cumulative effort of 9000 trap-nights, 18 photographs of southern spotted skunks corresponding to 15 independent events were obtained at four photo-trapping stations in the Calakmul region. At the photo-trapping stations, four photographic events were recorded in which solitary male individuals were observed, but it was not possible to identify whether the records correspond to one or more individuals. The few records of S. angustifrons in the Yucatan Peninsula may be due to the lack of mastozoological surveys in the region. The records reported in this note provide knowledge on the distribution, habitat, use of artificial watering places and interspecific relationships of S. angustifrons. Being a carnivore, it is likely that the ecological role of S. angustifrons in the Calakmul region is relevant, however the population and ecological aspects of the species are unknown, so it is necessary to conduct studies focused on the status of the populations of S. angustifrons.

RESUMO Os padrões de variabilidade espacial e temporal da qualidade da água foram avaliados através de coletas mensais de amostras de água (superfície, subsuperfície e fundo) de 2005 a 2012. A Análise de Componentes Principais foi utilizada para definir a importância relativa de cada variável e Anova (bidirecional) para analisar a significância das diferenças na qualidade da água no eixo longitudinal do reservatório. As variáveis: turbidez, transparência de Secchi, tempo de residência e temperatura têm maior importância na qualidade da água. Foram observados gradientes espaciais e temporais, relacionados aos processos de circulação, sedimentação e ressuspensão, e a influência da baixa vazão, alto tempo de residência e mistura invernal da coluna d'água na ciclagem de sólidos e nutrientes pode explicar a variação desses processos. A utilização de métodos de análise estatística multivariada forneceu informações importantes para a compreensão desses processos, auxilia na interpretação de dados complexos para melhorar o monitoramento e uso das informações para os tomadores de decisão.

ABSTRACT Spatial and temporal variability patterns of water quality were evaluated through monthly collection of water samples (surface, sub-surface and bottom) from 2005 to 2012. Principal Component Analysis was used to define the relative importance of each variable and Anova (two way) to analyze the significance of differences in water quality in the longitudinal axis of the reservoir. The variables: turbidity, Secchi transparency, residence time and temperature have greater importance on water quality. It was observed spatial and temporal gradients, related to the circulation, sedimentation and resuspension processes, and the influence of low flow, high residence time and winter mixing of water column on the cycling of solids and nutrients may explain the variation in these processes. The use of multivariate statistical analysis methods provided important information to understand these processes, it helps the interpretation of complex data to improve monitoring, and use of information to decision makers.

Abstract The aims of the present study were to examine the effects of D-galactose (DG) supplementation on plasma aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatinine, albumin, urea, bilirubin, cholesterol, and triglyceride. We also investigated the effects of Rosehip (Rosa canina L) fruit extraction and endurance exercise training on DG-induced changes in the aforementioned variables in male rats. Eighty-six male rats were randomly assigned to 8 groups 1) Control Saline 2) Training Saline 3) Control D-galactose 4) Training D-galactose 5) Control Rosehip 6) Training Rosehip 7) Control combined group and 8) Training combined group. Animals received experiments on the base of groups’ names (eight weeks and five times per week). Seventy-two hours after the last training or control session plasma was collected. The results showed that endurance training significantly increased plasma albumin while reducing ALT and creatinine. Rosehip significantly reduced plasma AST, creatinine, urea, cholesterol, and triglyceride, and increased bilirubin. A combination of training and Rosehip causes an additive effect compared to each intervention alone on AST. The use of DG increased ALT, AST, ALP, creatinine, urea, bilirubin, cholesterol, and triglyceride, while decreasing albumin. The use of Rosehip in combination with DG was able to minimize DG-induced abnormal elevation on some variables. In conclusion, using a high dose of D-galactose solution or high galactose content foods could make a precondition background for the non-alcoholic fatty liver which could be attenuated by crud Rosehip extraction. Thus, it seems that the Rosehip can be considered a hepatoprotective herb.

Abstract Introduction: This article summarizes the clinical practice guideline (CPG) for the initial pharmacological treatment of lupus nephritis in the Social Security of Peru (EsSalud). Objective: To provide evidence-based clinical recommendations for initial pharmacological treatment of non-refractory adults with class I to V lupus nephritis in EsSalud. Methods: A guideline development group (GDG) was formed, which included specialist physicians and methodologists, who formulated clinical questions. Systematic searches were conducted for systematic reviews and - when deemed relevant - primary studies in PubMed during 2021. Evidence was selected to answer each of the clinical questions posed. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic working meetings, the GEG used the GRADE methodology to review the evidence and formulate recommendations. The CPG was reviewed by external experts before its approval. Results: The CPG addressed 6 clinical questions, divided into 2 topics: initial treatment of the induction and maintenance phase. Based on these questions, 11 recommendations were formulated (all conditional), 22 points of good clinical practice, and 2 flow charts.

Resumen El presente artículo de revisión, tiene como objetivo caracterizar la aplicación de los inhibidores verdes para controlar la corrosión en metales, con el fin de mantener la seguridad y rentabilidad del proceso productivo, ya que, el fenómeno corrosivo no tiene solución, pero si puede mitigarse en el tiempo. Para el desarrollo del artículo, se adjuntan algunos casos de estudio relacionados con problemas por corrosión en metales, tales como: el accidente en Aloha y la explosión en Guadalajara. Posteriormente, se nombran las generalidades de los inhibidores para el control de la corrosión, en donde se comparan los procesos de fisisorción y quimisorción. Luego, se analizan los inhibidores inorgánicos, orgánicos, sintéticos y los verdes. Estos últimos buscan reemplazar a los sintéticos, mediante investigaciones de los inhibidores verdes obtenidos, por ejemplo, a partir de aloe vera y otro material vegetal.

Abstract This review article characterizes the green inhibitors applied to control corrosion in metals and maintain the safety and profitability of the production process, since the corrosive phenomenon is insoluble, but can be mitigated with time. For this article, some case studies related to corrosion problems in metals are included, such as the accident in Aloha and the explosion in Guadalajara. Subsequently, the generalities of inhibitors for corrosion control are named, and the physisorption and chemisorption processes are compared. Then, inorganic, organic, synthetic, and green inhibitors are analyzed. The latter seek to replace the synthetic ones, for example, through aloe vera and other plant materials.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.
