The use of visible and near infrared reflectance spectroscopy to predict beef M. longissimus thoracis et lumborum quality attributes

Visible and near infrared reflectance spectroscopy was used to predict pH at 24 h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner–Bratzler Shear Force (WBSF) and colour parameters (L*, a*, b*) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4 C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS calibrations for pH24, luminosity at 0 (L*t0) and 60 min (L*t60) showed good predictability (R2 = 0.97, 0.85 and 0.82; SECV = 0.10, 1.16, 1.36, respectively), whereas those related to the rest of the parameters were poore

Seedless watermelon, a cultural alternative to the portuguese horticulture

A melancia sem semente pode vir a ser um fruto popular para os consumidores portugueses se a produção for de elevada qualidade e rentável para os produtores. A Campina de Idanha-a-Nova apresenta excelentes características para a produção de culturas regadas em particular a melancia com semente, sendo já conhecida como uma região de excelência pela qualidade da sua produção neste fruto. Este trabalho resulta de um ensaio de produção de melancia sem semente ao ar livre, em camalhões, cobertura de solo e rega gota a gota, utilizando a cultivar (cv) Romalinda (cv. sem semente, triplóide) consociada em dois distintos compassos de plantação com a cv. Augusta (cultivar polinizadora, diploide). As modalidades consistiram de 2 repetições para camalhões de 4 linhas em que na Mod. I . a cv Romalinda e a cv Augusta se encontravam na proporção de 2:1 na linha( 50 plantas da cv. Romalinda e 25 plantas da cv. Augusta) e na Mod II. cada camalhão era constituído por uma linha da cv. Augusta intercalada com 2 linhas da cv. Romalinda (50 plantas da cv. Romalinda e 50 plantas da cv. Augusta) por camalhão. A análise da produção foi realizada escalonadamente, em três datas de colheita de julho a agosto, com 15 dias de intervalo. O ensaio foi realizado desde a sementeira à colheita e foram analisados os seguintes parâmetros produtivos: número de frutos; produtividade; peso dos frutos; espessura da casca; perímetro do fruto; altura e largura do fruto; grau brix; teores em matéria seca (MS), proteína (P), gordura (G) e matéria orgânica (MO). A adaptação da cv. sem semente foi excelente. Não se registaram diferenças significativas entre os parâmetros analisados e os compassos de plantação das modalidades ensaiadas. As plantas tiveram uma produção média de 3-4 frutos por planta; pesos médios entre 3,70kg e 4,20kg. O teor em açúcar foi aumentando da primeira para a última colheita atingindo valores médios de 11,53. Relativamente à composição química, a cultivar sem sementes apresentou valores mais elevados quanto à MS 6,23% (±1,34) (P>0,05), à G 0,29 % (±0,16) (P>0,05) e à MO de 92,47 % (±4,52) (P>0,05) e valor mais baixo de P (6,24 %MS ±1,28) (P<0,05). Conclui-se que a cv. Romalinda exibiu melhores características de produção quantitativa e qualitativamente do que a cv. Augusta sendo promissora como uma alternativa de produção tardia na região.SEEDLESS WATERMELON, A CULTURAL ALTERNATIVE TO THE PORTUGUESE HORTICULTURE ABSTRACT The seedless watermelon could be a popular fruit within Portuguese consumers if the quality of the crop is high and if it is profitable for growers. The agricultural area of Idanha-a-Nova has excellent characteristics for the production of irrigated crops, in particular common watermelon, being already renowned for the excellent quality of these fruits. One field experiment has been carried out to test the yield of seedless watermelon in open field conditions, with black polyethylene mulch and drip irrigation, using the cultivar Romalinda (seedless, triploid) with two planting spacings and the seeded watermelon cultivar Augusta (pollinating cultivar, diploid). The experiments were laid out in a randomized block design, with two replications, each with four rows. In block I the cv. Romalinda and cv. Augusta were in the ratio of 2:1, respectively, in each line (50 plants of cv. Romalinda and 25 plants of cv. Augusta) and in block II the trial area was planted on four beds with two rows of Augusta on either side of the trial (50 plants of cv. Romalinda and 50 plants of cv. Augusta). The fruit products were evaluated in three harvesting dates, every two weeks, from July to August. The following parameters were evaluated: number of fruits; total yield; fruit fresh weight; skin thickness; fruit perimeter; fruit height and width; sugar contents; dry matter (DM), protein (P), fat (G) and organic matter (OM). The adaptation of the seedless cultivar was excellent. There were no significant differences between the evaluated parameters and the blocks. The plants produced 3-4 fruits per plant with a weight between 3.7 and 4.2 Kg. The sugar contents increased from the first to the last harvest date, reaching an average value of 11.53. Dry matter was higher than on the seeded watermelon, reaching 6.23% (±1,34) (P>0,05), on average for a median value of 6.24% (±1,28) (P0,05) G and 92.47% (±4,52) (P>0,05) OM in dry matter. It can be concluded that the cv. Romalinda showed better quantitative and qualitative characteristics than the cv. Augusta, being promising as an alternative late crop for the region.

Do the strength levels predict the motor coordination in young basketball players?

The aim of this study was to analyse the relation between the strength levels and motor coordination in young basketball players. The sample of this study was composed by 12 basketball players with 15.83 (± 0.55) years old from the U-18 category. The players participate in the inter-regional, national championship round and national cup in 2015/2016 season. The upper limbs strength was evaluated with the push-up exercise, counting the number of repetitions in 30 seconds. The lower limbs strength was evaluated in centimetres with the horizontal jump without preparatory sprint. The motor coordination was evaluated with 6 cones separated by 1,5m in the diagonal. The athletes with ball, skirted the cones and ended with layup finalization, this exercise was measured in seconds. Spearman correlation test was accessed with a significance level of 5%. No significant correlation was observed between upper limbs strength and motor coordination (F =-0,259; p =0.208). However, a negative significant correlation was observed between lower limbs strength and coordination was observed (F =-0,539; p =0,035). Thus, basketball coaches should perform specific strength training seasons intending to improve the motor coordination. Improving strength levels may contribute for motor coordination improvement.info:eu-repo/semantics/publishedVersio

Growth inhibition of bacterial isolates recovered from two types of Portuguese dry smoked sausages (chouriço)

Potassium sorbate (PS), sodium benzoate (SB) and methyl p-hydroxybenzoate (MHB) were investigated as surface treatments for their ability to inhibit the growth of 18 isolates of spoilage and pathogenic bacteria from two types of Portuguese dry smoked sausages (Chouric o). MHB significantly inhibited the growth rate of 12 of the isolates (p < 0.05) whereas no effect was observed for four isolates of lactic acid bacteria, identified as Enterococcus faecium, Pediococcus acidilactici and Lactobacillus curvatus, and two isolates identified as Clostridium aminovalericum and Staphylococcus epidermidis. PS and SB had less influence on the bacterial growth rates. It was concluded that MHB can be applied as surface treatment to improve the stability and safety of the product along shelf life period in modified atmosphere packag

A Ranking Method to Prioritize VFR Airports to Be Provided With Instrument Approach Procedures

The primary purpose of this work is to investigate the necessity of a more comprehensive and systematic method to prioritize airports to be provided with instrument approach and landing procedures in the Brazilian air transportation landscape. An overview of the main contributors to risks associated with the approach and landing phases is provided, covering the most important aspects of unstable approaches and CFIT events. Considering the emergence of Terrain Awareness and Alerting Systems (TAWS), the role of its contribution to safety is discussed, as well as the certification context related to the design, installation, and operation of those systems. A ranking method is developed based on the analysis of TAWS alert events in several Brazilian airports. The method results in a ranking list of airports eligible for instrument procedures and points to objective means to improve safety, accessibility, and efficiency on the flight operations to those locations

Galerkin Method in the Gravitational Collapse: a Dynamical System Approach

We study the general dynamics of the spherically symmetric gravitational collapse of a massless scalar field. We apply the Galerkin projection method to transform a system of partial differential equations into a set of ordinary differential equations for modal coefficients, after a convenient truncation procedure, largely applied to problems of turbulence. In the present case, we have generated a finite dynamical system that reproduces the essential features of the dynamics of the gravitational collapse, even for a lower order of truncation. Each initial condition in the space of modal coefficients corresponds to a well definite spatial distribution of scalar field. Numerical experiments with the dynamical system show that depending on the strength of the scalar field packet, the formation of black-holes or the dispersion of the scalar field leaving behind flat spacetime are the two main outcomes. We also found numerical evidence that between both asymptotic states, there is a critical solution represented by a limit cycle in the modal space with period $\Delta u \approx 3.55$.Comment: 9 pages, revtex4, 10 ps figures; Phys.

Livro de comunicações: Jornada Técnica e Científica de Peixes de Rio – JTCPR’2023

A imensa Zona Económica Exclusiva faz com que, em Portugal, o conhecimento científico e técnico tenha sido orientado predominantemente para espécies piscícolas de água salgada. No entanto, no interior do continente português é tradicional o consumo de peixes de água doce, traduzida na organização de muitos festivais gastronómicos e na existência de muitos restaurantes que trabalham com peixe de rio, principalmente nas regiões do Ribatejo, Alentejo e Beira Baixa. Na Beira Baixa existe mesmo uma empresa, a Conserveira do Interior Lda., (https://www.conserveira-do-interior.pt/) que produz e comercializa iguarias de peixe de rio. O grande objetivo da JTCPR’2023 é debater questões relacionadas com investigação, conservação e valorização económica de espécies de peixes de água doce. Pretende reunir, no mesmo local, peritos portugueses e espanhóis, instituições de ensino superior, centros de investigação, organizações ligadas à conservação de espécies piscícolas e empresas vocacionadas para a transformação e valorização dos peixes de rio. Pretende destacar oportunidades para melhorar a proteção, a gestão e a valorização económica das espécies piscícolas de água doce existentes na Península Ibérica, numa lógica de conservação e preservação das bacias hidrográficas na sua globalidade, partilhando o conhecimento, estimulando a discussão construtiva e criando um ambiente de aprendizagem e colaboração.info:eu-repo/semantics/publishedVersio

Article Outline Patients and methods Results Discussion References Renal allograft rupture (RAR) is a rare but very serious complication of renal transplantation, requiring emergency surgery. The most common cause is acute allograft rejection, but other causes such as renal vein thrombosis (RVT), acute tubular necrosis (ATN), renal biopsy, and lymphatic obstruction have been reported.[1] and [2] We reviewed our experience with the aim of identifying RAR predisposing conditions. Patients and methods In a consecutive series of 934 renal transplants performed between July 1983 and September 1999, 11 patients (1.2%) had RAR. In these cases we studied donor and recipient characteristics, preservation conditions, clinical signs and symptoms, treatment, and pathology findings. This group of patients was then compared with their paired cohort. Data analysis was computer-based. In the statistical analysis t test and Fisher’s exact test were used. Results All 11 kidneys that suffered RAR were from cadaver donors, nine male and two female. The mean age was 29.5 years with good terminal serum creatinine (mean 1.1 mg/dL). All organs were stored in Eurocollins solution and the mean cold ischemia time was 21 hours and 25 minutes (range, 10 hours to 29 hours and 20 minutes). Excluding one black patient, all recipients were Caucasian. Eight were female and 3 were male, with a mean age of 33.8 years. The mean HLA match was 1.7, and the mean peak panel reactive antibody (PRA) was 22% (range 0 to 93%) and current was 15% (range 0 to 67%). All patients had cyclosporine treatment, eight had delayed graft function requiring dialysis, and three underwent renal allograft biopsy. In two patients rupture occurred in the second allograft; the others were first transplants. The day of RAR was a mean of 5.3 (range 2 to 13). All patients had new onset of severe allograft pain, eight had a drop in daily hematocrit, and six had hypotension. The four patients with more precocious ruptures had sudden onset of bleeding through the drainage tube. Transplant nephrectomy was performed in 10 patients, and surgical conservative treatment with fibrin glue and collagen foam was performed in one. All patients survived RAR. Three had a second transplant and currently have functioning allografts. Pathology examination revealed RVT in three patients and some degree of rejection in the remaining eight. One patient had a rupture on the second day because of hyperacute rejection, and three had severe acute cellular rejection, but in four patients the dominant figure was ATN with minimal rejection. Excluding the patient with hyperacute rejection, the day of rupture was later for those with severe acute rejection, a mean of 9.6 days (range 6 to 13). In those with ATN, the day of RAR was a mean of 4.5 (range 3 to 6) and the patients with RVT had ruptures even sooner, on mean third day (range 2 to 4). Variables associated with RAR were: sex mismatch (P = .004), current PRA (P = .012), and a need for dialysis (P = .042). Age of the recipient, transplant number, cold ischemia time, total HLA match, and peak PRA were not associated with RAR. Discussion Higher current PRA and a need for dialysis are variables associated with rejection and ATN. Therefore they are expected to be related to rupture. The well-documented conditions that are associated with ATN and rejection3 must be the same, which in extreme conditions predispose to RAR. We find no explanation for the statistically significant association of sex mismatch and RAR, other than random error. Acute allograft rejection is the most frequent cause of graft rupture in the literature (60 to 80%),3 but ATN has received little note. In our series, ATN was responsible for 36% of the ruptures, as much as severe acute rejection. ATN alone can cause RAR,4 because of interstitial edema and rise in intrarenal pressure. But when associated with rejection, it seems that these two conditions can act synergistically to cause allograft rupture. Our data suggests that rupture occurs later when caused by rejection, rather than when RVT is responsible. To our knowledge this finding had never been reported in world literature. Perhaps the timing of RVT is related to technical problems, such as twisting and kinking of the vein or intima tear, although the thrombogenic effect of cyclosporine can also have a role in this process.5 All these patients were on cyclosporine therapy, which may explain the small number of RAR caused by rejection alone and the significant number of patients that had RVT (27%). It appears that cyclosporine therapy is changing the etiology of the graft rupture.6 References 1 T. Grochowiecki, J. Szmidt and K. Madej et al., Transplantation Proc 28 (1996), p. 3461.
