Effects of Increasing Dietary Levels of Carinata Meal on Feeding Behavior, Performance and Carcass Characteristics of Beef Growing Steers
The objectives of the present study are to evaluate feeding behavior, animal performance and carcass characteristics of beef growing steers fed increasing amounts of carinata meal (CM). Due to the high protein content of the CM after the oil extraction for biofuel there is an opportunity to use it as a protein supplementation in beef cattle. Twenty-four steers blocked by weight were assigned to four corn-based diets (n = 6 animals per treatment). In the three treatment diets, carinata meal replaced high-moisture corn at 5, 10, or 15%. The diets were fed using the Insentec RIC system for 138 days. During the feeding period, individual feed disappearance, feeding behaviors, and growth performance were recorded. At the conclusion of the feeding period, the steers were harvested at a commercial abattoir where carcass characteristics were measured. Data were analyzed as randomized complete block with diet as the fixed effect and block as the random effect using the PROC MIXED procedure of SAS. Linear and quadratic contrast were used to evaluate the effect of incremental levels of CM in the diets. Steer was the experimental unit for all analyses and α-value of 0.05 was used to declare significance. Trends were identified when 0.05 ≤ P ≤ 0.10. A quadratic effect (P \u3c 0.01) was observed in DMI where DMI increased with incremental levels of CM up to 10% in the diets then decreased. Carinata meal had a quadratic effect on body weight on d 84 and 138 (P = 0.05 and 0.003, respectively). Body weights were lower in calves fed the control diet (CONT) and those fed the highest level of carinata meal (CM15). Carinata meal inclusion had a quadratic effect (P = 0.008) on overall average daily gain (ADG) in the finishing period. Calves fed lower levels of CM meal gained faster than those fed either 0 or 15%. Gain:feed was not affected by treatment (P = 0.11). There was a quadratic (P = 0.002) effect of CM inclusion on hot carcass weight (HCW). Weights increased from CONT to 5% CM meal (CM5) treatment, was consistent to 10% CM inclusion (CM10), and then decreased when CM was fed at 15% of the diet (CM15). There were no effects (P \u3e 0.05) of treatment on REA or MARB. There was a quadratic effect (P = 0.005) of CM inclusion on backfat (BF) in which BF increased from CONT to CM10, then decreased with incremental levels of CM. There was a quadratic change observed on % KPH (P = 0.02) and YG (P = 0.009). These variables increased from CONT to CM10, then decreased with CM15 in the diets. Dry matter meal size (DMMS) tended to increase from CONT to CM5 and CM10 and decreased at CM15 (Quadratic, P = 0.09). Inter meal interval (IMI) increased linearly (P \u3c 0.01) with incremental levels of CM in the diet. A linear decrease (P \u3c 0.001) in meal duration (MD) was observed as the level of CM increased in the diet. A quadratic effect of treatment on as-fed meal size (MS; P = 0.04) was observed with increasing levels of CM in the diet. As-fed meal size increased from CONT to CM5, then decreased as the level of CM inclusion increased in the diet. This research suggests that CM may be able to serve as a functional source of crude protein in beef cattle finishing diets, but there may be an upper inclusion limit without reducing performance. Further research needs to be completed to determine the value of CM as a protein supplement
Necrotizing Fasciitis Post- Acute Appendicitis
A Fasceíte Necrotizante (FN) é um processo infeccioso da fascia profunda, de evolução rápida e progressiva com necrose secundária do tecido celular subcutâneo. Os autores apresentam um caso de FN da parede abdominal, como complicação extremamente rara de apendicite aguda.
Trata-se de uma criança, apendicectomizada por apendicite aguda gangrenada, que evolui para quadro infeccioso grave, com dor e processo inflamatório da parede abdominal. Após diagnóstico, foi submetido a desbridamento cirúrgico da parede abdominal e drenagem de abcesso intraperitoneal. Realizada terapêutica antibiótica, desbridamentos cirúrgicos e pensos sucessivos da lesão e ao 22º dia efectuou-se enxerto dermo-epidérmico de área cruenta residual da parede abdominal. Porque o prognóstico está intimamente relacionado com o tempo decorrido até ao diagnóstico correcto e início de terapêutica adequada, é de extrema importância que este diagnóstico seja considerado
The precipitation field over Calabria: Large-scale correlations
In this paper we analyze the variability of the precipitation field over Calabria for the period 1948-1990 and its correlation with large-scale flow. Precipitation data are from “Istituto Mareografico ed Idrografico” database, have a monthly basis and cover the period
1921-1990. It is shown that precipitation is concentrated in the cold semester, from October to April, and that there is a large annual-to-annual variability. After studying correlation between precipitation and North Atlantic Oscillation (NAO), rainfall variability is further discussed by relating the precipitation standardized anomaly index to surface pressure, 500 hPa geopotential height and sea surface temperature. These dataset are derived from NCAR reanalysis project, and cover the
1948-2002 period. Due to temporal coverage of our databases the analysis is limited to 1948-1990. While a weaker correlation with NAO emerges, compared to other areas of the Mediterranean basin, precipitation over Calabria shows an interesting correlation with another dipolar structure located further East. This correlation is mainly related to the strength of Azores anticyclone over the Mediterranean area in the cold season and to the oscillation of Siberian high
Hurricane Matthew in 2100: effects of extreme sea level rise scenarios on a highly valued coastal area (Palm Beach, FL, USA)
Sea-level rise represents a severe hazard for populations living within low-elevation coastal zones and is already largely affecting coastal communities worldwide. As sea level continues to rise following unabated greenhouse gas emissions, the exposure of coastal communities to inundation and erosion will increase exponentially. These impacts will be further magnified under extreme storm conditions. In this paper, we focus on one of the most valuable coastal real estate markets globally (Palm Beach, FL). We use XBeach, an open-source hydro and morphodynamic model, to assess the impact of a major tropical cyclone (Hurricane Matthew, 2016) under three different sea-level scenarios. The first scenario (modern sea level) serves as a baseline against which other model runs are evaluated. The other two runs use different 2100 sea-level projections, localized to the study site: (i) IPCC RCP 8.5 (0.83 m by 2100) and (ii) same as (i), but including enhanced Antarctic ice loss (1.62 m by 2100). Our results show that the effective doubling of future sea level under heightened Antarctic ice loss amplifies flow velocity and wave height, leading to a 46% increase in eroded beach volume and the overtopping of coastal protection structures. This further exacerbates the vulnerability of coastal properties on the island, leading to significant increases in parcel inundation

Discovery of coherent millisecond X-ray pulsations in Aql X-1
We report the discovery of an episode of coherent millisecond X-ray pulsation
in the neutron star low-mass X-ray binary Aql X-1. The episode lasts for
slightly more than 150 seconds, during which the pulse frequency is consistent
with being constant. No X-ray burst or other evidence of thermonuclear burning
activity is seen in correspondence with the pulsation, which can thus be
identified as occurring in the persistent emission. The pulsation frequency is
550.27 Hz, very close (0.5 Hz higher) to the maximum reported frequency from
burst oscillations in this source. Hence we identify this frequency with the
neutron star spin frequency. The pulsed fraction is strongly energy dependent,
ranging from 10% (16-30 keV). We discuss possible physical
interpretations and their consequences for our understanding of the lack of
pulsation in most neutron star low-mass X-ray binaries. If interpreted as
accretion-powered pulsation, Aql X-1 might play a key role in understanding the
differences between pulsating and non-pulsating sources.Comment: 5 pages, 3 figures, accepted by ApJ Letters after minor revisions.
