The Relative Performance of a Benchtop Scanning Monochromator and Handheld Fourier Transform Near-Infrared Reflectance Spectrometer in Predicting Forage Nutritive Value

Advanced manufacturing techniques have enabled low-cost, on-chip spectrometers. Little research exists, however, on their performance relative to the state of technology systems. The present study compares the utility of a benchtop FOSS NIRSystems 6500 (FOSS) to a handheld NeoSpectra-Scanner (NEO) to develop models that predict the composition of dried and ground grass, and alfalfa forages. Mixed-species prediction models were developed for several forage constituents, and performance was assessed using an independent dataset. Prediction models developed with spectra from the FOSS instrument had a standard error of prediction (SEP, % DM) of 1.4, 1.8, 3.3, 1.0, 0.42, and 1.3, for neutral detergent fiber (NDF), true in vitro digestibility (IVTD), neutral detergent fiber digestibility (NDFD), acid detergent fiber (ADF), acid detergent lignin (ADL), and crude protein (CP), respectively. The R2P for these models ranged from 0.90 to 0.97. Models developed with the NEO resulted in an average increase in SEP of 0.14 and an average decrease in R2P of 0.002.

Development of Psi Factors for Thermal Bypass Due to Insulation Gaps in Low-Slope Roofing Assemblies

In commercial roofs, the presence or formation of gaps could be due to improper installation, thermal expansion, and dimensional changes in the insulation boards. The heat loss from these gaps could lead to higher thermal transmittance in the roof assembly. The current research study conducted around 70 experiments to investigate the effect of gap height, gap width and gap offset on the thermal transmittance of the roofing assembly. The measured data showed that in a staggered insulation layout with a joint offset of 610 mm (24 in), formation of 6.4 mm (1/4 in) to 12.7 mm (1/2 in) gaps at the insulation joints could contribute to an average decrease of 2% to 9% in the effective R-value of the roof assembly. As the insulation thermal resistance increases or becomes thicker, the thermal losses in the roof assembly increase. Generalized gap impact curves were developed to provide the relation between gap parameters (i.e., gap widths and height) and the thermal performance of the roof assembly. The experimental data were further analyzed using the psi factor approach of linear thermal bridging generating thermal transmittance data to support the calculation of thermal bypass from gaps in the thermal roof design.

DIRECTIONS OF STATE SUPPORT DIGITALIZATION OF AGRICULTURE OF RUSSIA

State support for the development of agriculture, like other subsidized industries, has a significant impact on the development of crop and livestock products, acting as a strategic bulwark of the country's food security. An increase in the volume of state support for agriculture is possible with the dynamic activity of all sectors of agriculture, the main task of which is to increase economic efficiency through the transition to innovative production principles. State support for the technical re-equipment of agribusiness is the basis of agricultural production, which has a decisive impact on the transition to digital solutions for the entire agrarian industry in the future. In this regard, the goal was set to analyze the effectiveness of the implementation of digital technologies using the example of typical agricultural enterprises of the Republic of Tatarstan located in different climatic zones of the Volga region, confirming an average decrease in the production cost of 1 centner of grain crops by 13%, payment labor on average by 14.5%, which makes it necessary to allocate financial support to agrarians as an effective mechanism for increasing the efficiency of agribusiness based on funds from the federal and regional budgets of the constituent entities of the Russian Federation and from extra-budgetary sources. Revealing the mechanism of state regulation in the form of tax, control and inspection, as well as the mechanism of state support and legal regulation, a mechanism of state support for the digitalization process is proposed in the form of subsidizing the costs of purchasing digital products, as one of the effective mechanisms, contributing to the acceleration of the transition of agribusiness to the digital economy. This mechanism will allow agrarians, at the first stage of the digitalization process of agricultural production, to acquire primary digital equipment in the form of trackers and sensors capable of receiving, sending, generating and processing data, which will subsequently lead to the need for the acquisition of interfaces capable of providing unhindered exchange of data between machines and business partners, and later portals in the form of ecosystems

Trauma Surgeon-Led and Funded Injury Prevention Program Decreases Number of All-Terrain Vehicle-Related Admissions

Background All-terrain vehicle (ATV) laws regarding helmet use, alcohol involvement, and roadway riding are poorly enforced or largely ignored. We hypothesized that direct surgeon funding and leadership in injury prevention would decrease ATV crashes. To focus prevention efforts, we reviewed a rural level 1 trauma center 11-year experience with ATV crashes comparing helmeted and unhelmeted rider outcomes. Methods For the latter 6 years of the study period, a trauma surgeon sponsored an injury prevention fund promoting ATV safety using simulators and discussions for area high school students. Helmet use, alcohol avoidance, and safe ATV operating were emphasized. A trauma registry review of ATV admissions from 2009 through 2020 examined demographics, helmet use, and clinical outcomes using chi-square, t-test, and regression analysis. Results Unhelmeted ATV riders suffered more severe head and neck injuries (OR 19, CI 1.5-1.8, P < .001), worse overall Injury Severity Score (ISS), (OR 25, CI 12.1-14.2, P < .001), and higher mortality rates (OR 4.0, CI .02-.05, P < .001). Helmet use corresponded with an average decrease in AIS and increase in GCS status. Although only 15% of riders were helmeted, ATV crash admissions have decreased in the last 5 years ( P < .001). Discussion All-terrain vehicle trauma and mortality is still frequent, especially in unhelmeted riders. The recent decrease in area ATV crashes is encouraging. Trauma surgeons have an opportunity to make a difference in public awareness and education through comprehensive physician-funded and directed injury prevention and research efforts.

Prediction and Control Model of Musculoskeletal Disorders in the Instant Noodle Company in Makassar 2020–2050

BACKGROUND: There are many risk factors that result in musculoskeletal disorders because of work. This also occurs in the instant food industry, where apart from manual load handling and repetitive work, the production process can also results in risks. AIM: The aims of this study are to predict the musculoskeletal disorders in the next 50 years and the effectiveness of scenarios for controlling musculoskeletal disorders. METHODS: This study employed Research and Development method through a dynamics system approach. This research was conducted in one of the industries that produce instant food in South Sulawesi, Indonesia. The data obtained was based on interviews, which were further analyzed using Interpretative Structural Modeling. RESULTS: Based on the simulation results for 30 years, it was found that there was an increase in the average musculoskeletal disorder incidence by 20.63% per year. At the end of the simulation in 2050, the number of musculoskeletal disorder incidents became 48481.69. In this case, the simulation for 30 years (2020–2050) was conducted on a model of controlling occupational diseases at an instant noodle company in Makassar by providing treatment in the form of reducing risk factors that cause musculoskeletal disorders. Based on the simulation results for 30 years (2020–2050), musculoskeletal disorders have the most significant contribution to the increase of occupational diseases incidents as a whole. The increase in musculoskeletal disorders is an accumulation of several risk factors that exist in the instant noodle production process. CONCLUSIONS: Prediction of the musculoskeletal disorder incidence using a dynamic system approach for 30 years (2020–2050) has increased by an average of 20.63% per year. The behavior of the model after receiving treatment on the occurrence of musculoskeletal disorders has an average decrease in the average incidence of 51.11% per year. In this case, to control the musculoskeletal disorder incidence, the elements or variables controlled simultaneously are work posture, lifting load, and length of work.

Trends in the content of acidifying and eutrophying compounds in atmospheric precipitation in an urbanized area

The trends in changing the content of sulfur and nitrogen in atmospheric precipitation in the territory of Minsk over an 18-year period are characterized on the basis of the analysis of the monitoring results of the chemical composition of atmospheric precipitation at the experimental site. A downtrend in the sulfur and nitrogen content combined with an uptrend in the precipitation acidity was identified. An average decrease (trend) in the content of sulfur in atmospheric precipitation for 2002–2019 was 0.019 mg S/dm3/year, of oxidized nitrogen – 0.008 mg/dm3, of reduced nitrogen – 0.019 mg/dm3. Over an 18-year period, the changes in the content of sulfur and nitrogen in atmospheric precipitation decreased the deposition of sulfur on average by 31.3 kg/km2/year, of oxidized nitrogen – by 15.4 kg/km2/year, of reduced nitrogen – by 25.6 kg/km2/year. It is shown that for the period from 2005 to 2012, the acidification potential of the natural environment decreased parallel to the reduction of the sulfur and nitrogen deposition; in the subsequent period, the trend of the acidification potential basically follows the trend of the precipitation of the main cations. It is revealed that the rates of average reduction in the content of oxidized sulfur and oxidized nitrogen in atmospheric precipitation in Minsk for the period from 2002 to 2017 are comparable to the rates of reduction of these compounds at the stations of the EMEP Program in Europe, and exceed those for reduced nitrogen.

POTENSI BIJI JARAK PAGAR SEBAGAI RODENTISIDA ALAMI

[JATROPHA SEED POTENTIAL AS A NATURAL RODENTICIDE]. The controlling of rat's pest attacks often use chemical control that adversely affects non-target animals and leaves a residue for the environment. One of the recommended controls is to use natural rodenticides derived from jatropha seeds and do not harm non-target animals that are environmentally friendly. This research aims to determine the interaction and the best combination of bait mixed with jatropha seeds on the death of Mus musculus, as well as the type of bait and the best dose of jatropha seeds on the death of Mus musculus. The design in this study used a completely randomized design consisting of two factors, the first factor was the bait and the second factor was the dose of jatropha seeds. The results showed that there was an interaction between the type of bait and the dose of jatropha seeds on the amount of feed consumed by Mus musculus. The combination of bait type and dose of jatropha seeds that was best for the mortality of Mus musculus was found in the treatment of rice flour with 3.0 g of jatropha seeds, cornflour with 3.0 g of jatropha seeds, and fish meal with 3.0 g of jatropha seeds. The best dose of jatropha seeds in reducing the bodyweight of Mus musculus, accelerating the time of death, and increasing the percentage of death was 3.0 g of jatropha seeds with an average decrease in body weight of Mus musculus reaching 75%, and the fastest death for five days, and able to kill 100% of Mus musculus.

A statistical technique for determination of withdrawal of northeast monsoon over coastal Tamilnadu

The withdrawal dates of northeast monsoon over coastal Tamil Nadu for the 90-year period (1901-90) have been objectively derived. The methodology of determination was generally based on an index based on the spatial distribution of daily rainfall over stations of coastal Tamil Nadu, over a 5-day pentad for the six month period, September- February. The normal withdrawal date thus obtained was 27 December with a standard deviation of 13.6 days and range 23 November-28 January. The duration of northeast monsoon was distributed with mean 67.5 days, standard deviation 14.9 days and range 26-102 days. During 36.7 % of years the withdrawal spilled over to January of next year. The daily normal rainfall and its difference filter have been discussed with reference to the normal date of withdrawal. The average decrease of rainfall at the time of withdrawal has been derived by application of superposed epoch analysis. It has further been shown that during years when the withdrawal took place in January the intensity of northeast monsoon prior to withdrawal was as intense as in years when withdrawal occurred in December. A few cases of northeast monsoon withdrawal have been illustrated with diagrams. As no definite dynamic or thermodynamic features could be uniquely identified which are associated with the withdrawal, this technique is basically statistical, considering the behaviour of the daily normal rainfall as the sole criterion. Unique thermodynamic and dynamic features are not identifiable which are associated with the withdrawal of northeast monsoon over coastal Tamilnadu.
