The results of an agricultural analysis of the ERTS-1 MSS data at the Johnson Space Center

The initial analysis of the ERTS-1 multispectral scanner (MSS) data at the Johnson Space Center (JSC), Houston, Texas is discussed. The primary data set utilized was the scene over Monterey Bay, California, on July 25, 1972, NASA ERTS ID No. 1002-18134. It was submitted to both computerized and image interpretative processing. An area in the San Joaquin Valley was submitted to an intensive evaluation of the ability of the data to (1) discriminate between crop types and (2) to provide a reasonably accurate area measurement of agricultural features of interest. The results indicate that the ERTS-1 MSS data is capable of providing the identifications and area extent of agricultural lands and field crop types

Incidence of Salmonellae In Some Meat Products

Fresh pork sausage, biltong, beef mince and chicken carcasses available to the consumer in Pretoria, were examined for salmonellae using standard enrichment, plating and biochemical techniques. The incidence of salmonellae in pork sausage was 40% and in beef mince 64%. The frequent occurrence of salmonellae in biltong (16% of the samples) makes consumption a serious health hazard, since it is eaten raw. Salmonellae were found in 20% of the chicken carcasses, but contamination seemed to be associated mainly with one processor. Where data could be compared with previous local surveys (beef mince and biltong), it appears that the incidence of salmonellae is increasing. The most frequently isolated serotypes of salmonellae in this study were Salmonella typhimurium and Salmonella thompson. The results indicate the need for greater 'microbiological control in the meat industry

The 1980 US/Canada wheat and barley exploratory experiment. Volume 2: Addenda

Three study areas supporting the U.S./Canada Wheat and Barley Exploratory Experiment are discussed including an evaluation of the experiment shakedown test analyst labeling results, an evaluation of the crop proportion estimate procedure 1A component, and the evaluation of spring wheat and barley crop calendar models for the 1979 crop year

Introducing the Gender Dimension of Plastic Pollution in the Arctic

This short communication seeks to introduce a new perspective – a gender dimension – into ongoing conversations on the governance of plastic pollution in the Arctic. Specifically, it seeks to understand (1) the degree to which gender and plastic pollution intersect in Arctic research and policy-making to date; and (2) the degree to which negotiations of the UN Treaty on Plastic Pollution integrate diverse gender perspectives from the North. We first consider the extent of the plastics problem in the Arctic and the degree to which existing research addresses its gender-dimension. Then, we introduce existing regional and global responses to the plastics problem, including ongoing negotiations for a United Nations treaty on plastic pollution. Finally, we examine the degree to which gender has been mainstreamed into these governance mechanisms

Lipid Synthesis in the Beef Animal

Rates of in vitro fat synthesis from acetate and lactate were compared to the activities of enzymes thought to be involved in the process of lipid synthesis from lactate. Results of these studies indicate that lactate can be incorporated into fats by a pathway heretofore thought to be nonfunctional in ruminants, the citrate cleavage:malic enzyme pathway. Studies of the effects of age and diet on the enzymes of the citrate cleavage:malic enzyme pathway support the concept of a physiological role for this pathway in lipid synthesis in beef cattle

Crossover from diffusive to strongly localized regime in two-dimensional systems

We have studied the conductance distribution function of two-dimensional disordered noninteracting systems in the crossover regime between the diffusive and the localized phases. The distribution is entirely determined by the mean conductance, g, in agreement with the strong version of the single-parameter scaling hypothesis. The distribution seems to change drastically at a critical value very close to one. For conductances larger than this critical value, the distribution is roughly Gaussian while for smaller values it resembles a log-normal distribution. The two distributions match at the critical point with an often appreciable change in behavior. This matching implies a jump in the first derivative of the distribution which does not seem to disappear as system size increases. We have also studied 1/g corrections to the skewness to quantify the deviation of the distribution from a Gaussian function in the diffusive regime.Comment: 4 pages, 4 figure

Running-Related Injury Incidence: Does It Correlate with Kinematic Sub-groups of Runners? A Scoping Review.

BACKGROUND: Historically, kinematic measures have been compared across injured and non-injured groups of runners, failing to take into account variability in kinematic patterns that exist independent of injury, and resulting in false positives. Research led by gait patterns and not pre-defined injury status is called for, to better understand running-related injury (RRI) aetiology and within- and between-group variability. OBJECTIVES: Synthesise evidence for the existence of distinct kinematic sub-groups across a population of injured and healthy runners and assess between-group variability in kinematics, demographics and injury incidence. DATA SOURCES: Electronic database search: PubMed, Web of Science, Cochrane Central Register of Controlled Trials (Wiley), Embase, OVID, Scopus. ELIGIBILITY CRITERIA: Original, peer-reviewed, research articles, published from database start to August 2022 and limited to English language were searched for quantitative and mixed-methods full-text studies that clustered injured runners according to kinematic variables. RESULTS: Five studies (n = 690) were included in the review. All studies detected the presence of distinct kinematic sub-groups of runners through cluster analysis. Sub-groups were defined by multiple differences in hip, knee and foot kinematics. Sex, step rate and running speed also varied significantly between groups. Random injury dispersal across sub-groups suggests no strong evidence for an association between kinematic sub-groups and injury type or location. CONCLUSION: Sub-groups containing homogeneous gait patterns exist across healthy and injured populations of runners. It is likely that a single injury may be represented by multiple movement patterns, and therefore kinematics may not predict injury risk. Research to better understand the underlying causes of kinematic variability, and their associations with RRI, is warranted

Elfazepam and Synovex-S Influences on Growth and Carcass Characteristics of Steers Fed Two Dietary Energy Levels

Synovex-S improves the average daily gain and carcass traits of steers and reduces losses under high feed price levels when compared to nonimplanted steers. High energy diets also influence average daily gain (ADG) favorably, but they increase the amount of fat and decrease the protein in carcass soft tissue in comparison to low energy diets
