Authors: La Monica Michael , Ziegenfuss Tim , Lopez Hector 
Published: January 2022

Introduction: Many consumers use dietary supplements in the hopes of increasing energy and burning more calories, which if sustained over time may help accelerate weight loss. The purpose of this clinical trial was to investigate the effects of an over-the-counter thermogenic supplement called Burn-XT™ (BXT) on metabolic rate, substrate oxidation, and various psychometric indices of affect that impact weight management.
Methods: Using a double-blind, placebo-controlled, cross-over design, 16 women and 10 men (29.3 ± 7.3 yr, 169.4 ± 8.6 cm, 75.5 ± 14.3 kg) underwent two testing sessions: placebo (PL) and BXT. Seated metabolic rate and substrate oxidation, vital signs, and anchored visual analogue scale (VAS) assessments of energy, mood, motivation, focus, fatigue, concentration, and appetite were made before supplementation and hourly for three hours post-ingestion. Two-factor (2x4) factorial ANOVAs and paired sample t-tests (corrected for multiple comparisons) were used for analyses.
Results: Significant increases in metabolic rate (oxygen consumption) were noted at 60 minutes in BXT (+11.9 mL O2/min) vs. PL (-2.5 mL O2/min), p = 0.004, d = -0.74. Only BXT increased metabolic rate compared to baseline at 60 minutes (+11.9 mL O2/min, p = 0.021, d = -0.53) and 120 minutes (+12.1 mL O2/min, p = 0.019, d = -0.54). The AUC for resting energy expenditure increased more in BXT vs. PL (p = 0.007, d = -0.57). VAS detected significant improvements in energy, mood, focus, and concentration for BXT vs. PL at 120 and 180 minutes (all p < 0.05, d = -0.58 to -0.68). In all cases, within-group changes from baseline for these VAS parameters were significant (all p < 0.05, d = -0.76 to -1.38) in BXT but not in PL. No within or between group differences in appetite, substrate oxidation, or heart rate were noted. Small (~3-4 mm Hg), but statistically significant (p < 0.05, d = -0.51 to -0.69) increases in diastolic blood pressure were noted in BXT at 60, 120, and 180 min vs. PL; and in systolic blood pressure at 60 min vs. PL. In all cases, values remained within normal clinical hemodynamic ranges.
Conclusions: A single dose of BXT safely increased metabolic rate, energy, mood, focus, and concentration. Given that these factors are known to favorably impact weight management, future studies should determine whether daily supplementation with BXT reduces body weight and improves body composition.

Prevalence of Back and Neck Pain in Orthopaedic Surgeons in Western New York
Authors: Lucasti Christopher , Maraschiello Mark , Slowinski Josh , Kowalski Joseph 
Published: January 2022

Introduction:
The physical requirement of orthopaedic surgeons makes them highly vulnerable to musculoskeletal (MSK) injury. Previous studies have shown the prevalence of back and neck pain in orthopaedic surgeons to be approximately 50%. We hypothesize the prevalence of back and neck pain in orthopaedic surgeons in the Western New York region to be similar to what has been previously reported.

Methods:
A survey was sent through e-mail to all actively practicing orthopaedic surgeons in Western New York. A total of 94 surgeons were asked to participate, and 53 responded. Data for demographics, back pain, neck pain, and the impact of MSK pain on lifestyle and career practices were collected and compared with previous research.

Results:
Seventy-seven percent of respondents reported back pain, whereas 74% reported neck pain, both of which are greater than those seen previously. Sixteen surgeons reported receiving medical treatment currently or in the past for their MSK pain. Fourteen surgeons said that their pain has caused them to adapt their practice and/or operating room setup.

Conclusion:
We found the prevalence of back and neck pain in this population to be higher than that previously reported. Additional investigation into the possible causes of the higher prevalence should include the number of arthroscopic procedures done, the amount of time spent wearing lead vests, and the number of hours spent in the operating room by residents.

The experiment was conducted to find out the effect of ginger extract on the sensory, physicochemical and biochemical properties of spent hen sausages. For this purpose, sausages were prepared into four different groups. They were as follows: broiler breast meat sausage without ginger extract, spent hen breast meat sausage without ginger extract, spent hen breast meat sausage with 2% ginger extract and spent hen breast meat sausage with 4% ginger extract. All parameters were analyzed at 0, 15th and 30th days of storage time. The proximate compositions of different sausage batters are analyzed and highly significant differences were found in pH, dry matter (DM)%, crude protein (CP)% and ether extract (EE)%, while no significant differences were found in cooking loss (%) and Ash (%) of sausage batter. While analyzing the different types of sausages, DM, CP and EE content of all treatments differ significantly (p<0.01). In contrast, DM and CP content increased significantly (p<0.01) with the advancement of different days of intervals. The FFA, POV and TBARS values were increased significantly (p<0.01) with prolonging the storage time. Significant differences were found among the sausages for its surface color. Flavor and overall acceptability were found significantly higher in broiler breast meat sausage and spent hen breast meat sausage with 2% ginger extract. Juiciness and tenderness were higher in broiler breast meat sausage without ginger extract. Worst results in all sensory parameters were found in spent hen breast meat sausage without ginger extract and spent hen breast meat sausages incorporated with 4% ginger extract. It might be concluded that addition of ginger extract at 2% level increased the overall acceptability of spent hen breast meat sausages to that of broiler breast meat sausages.

Published: January 2022

A descoberta da bacia de Santos, em 2007, mostrou oportunidades do uso do gás natural obtido da exploração do petróleo do Pré-sal. Em 2011, a Petrobras iniciou estudos para expansão do gasoduto de transporte para aproveitar esta riqueza. A expansão da rede visava abastecer termelétricas, indústrias e demais consumidores. Promovendo a substituição pelo gás de fontes energéticas mais caras e poluentes, lenha, carvão e óleo combustível. Favorecendo assim a competitividade empresarial, o ambiente, a segurança de fornecimento e a redução dos custos de produção. Uma parte da expansão foi operacionalizada com resultados considerados satisfatórios conforme o plano energético nacional. Em 2019, a quebra do monopólio do gás da Petrobras, desinteressando-a a continuidade do negócio, abrindo espaço para entrantes. A pesquisa que propiciou este artigo de caráter exploratório, tem forte apoio em documentos públicos e privados produzidos por instituições especializadas do setor. Consultas foram feitas a artigos e especialistas no assunto.
Stochastic Inversion Framework to Monitor Evolving Mass Properties of a Ship at Sea during Arctic Operations
Authors: Lin Yolanda C. , Earls Christopher J. 
Published: January 2022

This work investigates the indirect monitoring of Arctic ice accretion on ship surfaces using a stochastic inversion framework. An accurate assessment of a ship’s mass properties during operation is an important concern for ships traveling in adverse conditions. Specifically, in the Arctic, the risk of ice accumulation on the topside of the ship is heightened. Within such contexts, the actual, or current, first and second moment properties of the vessel, including accumulated topside icing, become critical in the associated equations of motion for a given ship. By leveraging an existing on-board inertial measurement unit in conjunction with existing seakeeping software, the framework here recovers a posterior distribution of a single mass property. The inverse problem is demonstrated with two mass properties: the vertical center of gravity (a first moment mass property), and the roll gyradius (a second moment mass property).
The inversion scheme requires two main inputs: an observed ground truth for the roll period, and an associated signal-to-noise ratio for the roll period measurement. The framework applies a Markov chain Monte Carlo (MCMC) inversion scheme, implemented in Python, that leverages Standard Ship Motion Program (SMP95) software in order to build a posterior distribution. Experimental model results from Research Vessel (R/V) Melville – Model 5748 provide the necessary inputs to the inversion scheme. Six different configurations, including one case of no icing and five cases of topside icing, are investigated within the context of this framework at full-scale from model-scale in order to invert for the six respective roll gyradii and vertical center of gravities. Icing configurations include both asymmetric and symmetric ice accumulation under moderate to heavy icing conditions.
Uvariopsis dicaprio (Annonaceae) a new tree species with notes on its pollination biology, and the Critically Endangered narrowly endemic plant species of the Ebo Forest, Cameroon
Authors: Gosline George , Cheek Martin , Onana Jean Michel , Ngansop Tchatchouang Eric , van der Burgt Xander M. , MacKinnon Lorna , Dagallier Léo-Paul M. J. 
Published: January 2022

Background
The Ebo Forest area is a highly threatened centre of diversity in the Littoral Region of Cameroon, globally important for conservation with many threatened species including 68 threatened species of plant, yet not formally protected. The tropical African evergreen forest tree genus Uvariopsis Engl. & Diels (Annonaceae) is characterised by unisexual, usually cauliflorous flowers with a uniseriate corolla of four petals, and two sepals. Cameroon is the centre of diversity of the genus with 14 of the 19 known species.

Methods
The herbarium collection MacKinnon 51 from Ebo is hypothesized to represent a new species to science of Uvariopsis. This hypothesis is tested by the study of herbarium specimens from a number of herbaria known to hold important collections from Cameroon and surrounding countries.

Results
We test the hypothesis that MacKinnon 51 represents a new species to science, using the most recent dichotomous identification key, and comparing it morphologically with reference material of all known species of the genus. We make a detailed comparative morphological study focussing on three other Cameroonian species, Uvariopsis solheidii, U. korupensis and the sympatric U. submontana. In the context of a review of the pollination biology of Uvariopsis, we speculate that in a genus otherwise with species with dull, flesh-coloured (pink, red to brown) flowers pollinated (where known) by diptera, orthoptera and blattodea (flies, crickets and cockroaches), the glossy, pale yellow-green flowers of Uvariopsis dicaprio, with additional traits unique in the genus, may be pollinated by nocturnal moths. Based on MacKinnon 51, we formally name Uvariopsis dicaprio Cheek & Gosline (Annonaceae) as new to science, and we describe, and illustrate, and map it. Restricted so far to a single site in evergreen forest in the Ebo Forest, Littoral Region, Cameroon, Uvariopsis dicaprio is provisionally assessed as Critically Endangered using the IUCN, 2012 standard because the forest habitat of this species remains unprotected, and there exist imminent threats of logging and conversion to plantations.

Discussion
We show that the highest density of species of the genus (12), and of narrow endemics (5), is found in the Cross-Sanaga Interval of SE Nigeria and Western Cameroon. A revised key to the 14 Cameroonian species of Uvariopsis is presented. We review the other seven narrowly endemic and threatened species unique to the Ebo forest of Cameroon and discuss the phytogeographic affinities of the area.

Conclusions
Uvariopsis dicaprio adds to the growing list of species threatened with extinction at Ebo Forest due to current anthropogenic pressures.
Psychometric properties of the Valuing Questionnaire in a Spaniard sample and factorial equivalence with a Colombian sample
Authors: Ruiz Francisco J. , Odriozola-González Paula , Suárez-Falcón Juan C. , Segura-Vargas Miguel A. 
Published: January 2022

BackgroundThe Valuing Questionnaire (VQ) is considered as one of the most psychometrically robust instruments to measure valued living according to the acceptance and commitment therapy model. It consists of 10 items that are responded to on a 7-point Likert-type scale and has two factors: Progression and Obstruction. The Spanish version of the VQ showed good psychometric properties in Colombian samples. However, there is no evidence of the psychometric properties of the VQ in Spaniard samples. This study aims to analyze the validity of the VQ in a large Spaniard sample and analyze the measurement invariance with a similar Colombian sample.MethodThe VQ was administered to a Spaniard sample of 846 adult participants from general online population. Cronbach’s alpha and McDonald’s omega were computed to analyze the internal consistency of the VQ. The fit of the VQ’s two-factor model was tested through a confirmatory factor analysis with a robust maximum likelihood (MLR) estimation method. Afterward, we analyzed the measurement invariance across countries and gender. Convergent construct validity was analyzed with a package of questionnaires that evaluated experiential avoidance (Acceptance and Action Questionnaire-II, AAQ-II), emotional symptoms (Depression Anxiety and Stress Scale-21, DASS-21), life satisfaction (Satisfaction with Life Scale, SWLS), and cognitive fusion (Cognitive Fusion Questionnaire, CFQ).ResultsThe internal consistency across samples was adequate (alphas and omegas were .85 for VQ-Progress and .84 for VQ-Obstruction). The two-factor model obtained a good fit to the data (RMSEA = 0.073, 90% CI [0.063, 0.083], CFI = 0.98, NNFI = 0.97, and SRMR = 0.053). The VQ showed strict invariance across countries and gender and showed theoretically coherent correlations with emotional symptoms, life satisfaction, experiential avoidance, and cognitive fusion. In conclusion, the Spanish version of the VQ demonstrated good psychometric properties in a large Spaniard sample.
Estimation of Sediments in Rengali Reservoir, Odisha (India) Using Remote Sensing
Authors: Mishra Siba Prasad , Kumar Chandan , Mishra Abhisek , Mishra Saswat , Patel Ashish 
Published: January 2022

Reservoir sedimentation is a regular process and sequential path of sedimentation in reservoirs comprising of erosion, entrainment, transference, deposition and compaction of dregs carried into artificial lakes formed behind the dams. India houses 5334 large dams in function (2329 numbers before 1980) and 411 dams are in pipeline. The Rengali dam, functioned from 1984, that traps 50% of the total sediment load of the Brahmani River continues to thwart the growth and buffering of the Brahmani delta.
Remote sensing (RS) and Geographical Information System (GIS) have emerged as powerful tools to create spatial inventory on Hydro-Bio-geo resources and the state of the environment. The RS/GIS and process-based modelling employed in spatial and dynamic assessment of loss in live storage of the reservoir by developing contour, aspect and slope map by using data received from LANDSAT sources.
The sedimentation of the Rengali reservoir (functional from 1984) studied for three decades 1990-2000; 2000-2010 and 2010- 2020 by constructing contour, aspect and water spread area maps by using web based data (satellite downloads). The web based water spread area data analysed by GIS tool for integration, spatial analysis, and visual presentations.
The results revealed that the decadal rate of sedimentation of Rengali reservoir is reducing with age. An appropriate reservoir operation and management system as per defined protocols considering sediment related problems is essential for controlling the ageing processes that may diminish the safety and shorten the reservoir life.
