Effect of clipping treatments on four winter grain

Tennessee farmers who regularly grow small grains as a part of their cropping system have long realized that these crops may provide extremely valuable winter and early spring grazing. Little data are available, however, to aid these farmers in choosing the most desirable pasturing practices to use in grazing such crops. Specifically, information is lacking on how intensively the small grains can be grazed without severe injury to the grain yield, the period in the growing season that each provides maximum pasturage, and the crop, or crops, furnishing the greatest amount of pasturage with the least reduction in grain yield. Until data are available on these problems, definite grazing practices cannot be recommended. This investigation was conducted to obtain information that could be applied toward the solution of the problems mentioned above. Briefly, the plan of the experiment was to simulate four intensities of grazing on adapted winter varieties of wheat, oats, rye, and barley. Since facilities were not available for conducting actual grazing trials, a lawn mower was used to remove the herbage

Manganese tricarbonyl complexes with asymmetric 2 2‑iminopyridine ligands: toward decoupling steric and electronic 3 factors in electrocatalytic CO2 reduction

Manganese tricarbonyl bromide complexes incorporating IP (2-(phenylimino)pyridine) derivatives, [MnBr(CO)3(IP)], are demonstrated as a new group of catalysts for CO2 reduction, which represent the first example of utilization of (phenylimino)pyridine ligands on manganese centers for this purpose. The key feature is the asymmetric structure of the redox-noninnocent ligand that permits independent tuning of its steric and electronic properties. The α-diimine ligands and five new Mn(I) compounds have been synthesized, isolated in high yields, and fully characterized, including X-ray crystallography. Their electrochemical and electrocatalytic behavior was investigated using cyclic voltammetry and UV−vis−IR spectroelectrochemistry within an OTTLE cell. Mechanistic investigations under an inert atmosphere have revealed differences in the nature of the reduction products as a function of steric bulk of the ligand. The direct ECE (electrochemical−chemical−electrochemical) formation of a five-coordinate anion [Mn(CO)3(IP)]−, a product of two-electron reduction of the parent complex, is observed in the case of the bulky DIPIMP (2-[((2,6-diisopropylphenyl)imino)methyl]pyridine), TBIMP (2-[((2-tert-butylphenyl)imino)methyl]-pyridine), and TBIEP (2-[((2-tert-butylphenyl)imino)ethyl]pyridine) derivatives. This process is replaced for the least sterically demanding IP ligand in [MnBr(CO)3(IMP)] (2-[(phenylimino)methyl]pyridine) by the stepwise formation of such a monoanion via an ECEC(E) mechanism involving also the intermediate Mn−Mn dimer [Mn(CO)3(IMP)]2. The complex [MnBr(CO)3(IPIMP)] (2-[((2-diisopropylphenyl)imino)methyl]pyridine), which carries a moderately electron donating, moderately bulky IP ligand, shows an intermediate behavior where both the five-coordinate anion and its dimeric precursor are jointly detected on the time scale of the spectroelectrochemical experiments. Under an atmosphere of CO2 the studied complexes, except for the DIPIMP derivative, rapidly coordinate CO2, forming stable bicarbonate intermediates, with no dimer being observed. Such behavior indicates that the CO2 binding is outcompeting another pathway: viz., the dimerization reaction between the five-coordinate anion and the neutral parent complex. The bicarbonate intermediate species undergo reduction at more negative potentials (ca. −2.2 V vs Fc/Fc+ ), recovering [Mn(CO)3(IP)]− and triggering the catalytic production of CO

Optimization of Energy Consumption in 5G Networks Using Learning Algorithms in Reinforcement Learning

The 5G network is an evolution of the 4G LTE (Long Term Evolution) fast internet network that is widely adopted in smart phones or gadgets. 5G networks offer faster wireless internet for various purposes. This research is a literature review of several articles related to machine learning, specifically regarding energy consumption optimization with 5G networks and reinforcement learning algorithms.The results show that various techniques have evolved to overcome the complexity of large energy intake including integration with 5G networks and algorithms have been completed by many researchers. Related to electricity consumption, it was found that during 5G use cases, in a low site visitor load scenario and while reducing power intake takes precedence over QoS, power savings can be made by 80% with 50 ms latency, 75% with 20 ms and 10 ms latency, and 20% with 1 ms latency. If QoS is prioritized, then power savings reach a maximum of five percent with minimum impact in terms of latency. Moreover, with regards to power performance, it has been observed that DQN-assisted motion can offer improvements

Accessing an Assisted Death from the UK: Navigating the Legal ‘Grey’ Area

Britons seeking an assisted death must travel to Switzerland. This article explores the experiences of UK-based individuals considering an assisted death and family members of those who have completed an assisted death. We recruited 11 participants across two qualitative studies, analyzing data using Interpretative Phenomenological Analysis. These results indicated four themes: the "burden" of illness; the value of autonomy and control over death; the difficulties of talking about assisted dying; and the barriers associated with pursuing an assisted death. The findings suggest there are individuals in the UK who will seek an assisted death, despite its illegality. Those involved in these journeys are not currently able to access support and more needs to be done to ensure their needs are met.Peer reviewe

Calorimetric Measurement of Latent Heats of Vaporization of Propane and Normal Pentane and Some Thermodynamic Properties of Normal Pentane

Measurements of the latent heat of vaporization of propane and normal pentane were made with an adiabatic bomb calorimeter. The temperature range for propane was from 103.4° F. to 163.2° F. Normal pentane measurements were from 103.7 to 200° Fahrenheit. A description of the apparatus and the method of calculation will be found in part 1 of this paper. In the second section of this paper some of the thermodynamic properties of n-pentane in the superheated gas region were calculated. Included in this section are tabulated values of entropy, enthalpy, residual volume, and heat capacity.</p

NWT-02, a fixed combination of lutein, zeaxanthin and docosahexaenoic acid in egg yolk and reduction of the loss of vision:evaluation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006

Following an application from Newtricious R&amp;D B.V., submitted for authorisation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 via the Competent Authority of the Netherlands, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to NWT-02 and a reduction of the loss of vision. The food proposed by the applicant as the subject of the health claim is NWT-02. NWT-02 is standardised by its content in lutein (≥ 1.10 mg), zeaxanthin (≥ 0.20 mg) and docosahexaenoic acid (DHA) (≥ 170 mg). The Panel considers that the food/constituent that is the subject of the health claim, NWT-02, a fixed combination of lutein, zeaxanthin and docosahexaenoic acid in egg yolk, is sufficiently characterised. The claimed effect proposed by the applicant is ‘reduces loss of vision’. The target population proposed by the applicant is ‘healthy adults over 50 years of age’. The Panel considers that a reduction of the loss of vision is a beneficial physiological effect. The applicant provided two human intervention studies for the scientific substantiation of the claim. The Panel considers that the only study from which conclusions can be drawn for the scientific substantiation of the claim did not show an effect of NWT-02 on vision. The Panel concludes that a cause and effect relationship has not been established between the consumption of NWT-02, a fixed combination of lutein, zeaxanthin and docosahexaenoic acid in egg yolk, and a reduction of the loss of vision.</p

Symbiosal^®and lowering of blood pressure and reduced risk of hypertension:evaluation of a health claim pursuant to Article 14 of Regulation (EC) No 1924/2006

Following an application from Han-Biotech GmbH, submitted for authorisation of a health claim pursuant to Article 14 of Regulation (EC) No 1924/2006 via the Competent Authority of Germany, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA) was asked to deliver an opinion on the scientific substantiation of a health claim related to Symbiosal® , lowering of blood pressure and reduced risk of hypertension. The Panel considers that the food, Symbiosal® , which is the subject of the health claim, and the food, table salt, which Symbiosal® should replace, are sufficiently characterised. Lowering of blood pressure is a beneficial physiological effect. Increased blood pressure is a risk factor for hypertension. In weighing the evidence, the Panel took into account that one human study with some methodological limitations showed an effect of Symbiosal® on blood pressure in the context of a self-selected diet with a maximum of 3 g/day added salt. The Panel also took into account that no other human studies in which these results have been replicated were provided, that the animal studies did not support the results of the human study, that no evidence was provided in support of a mechanism by which Symbiosal® could induce a decrease in blood pressure upon oral consumption as compared to table salt in vivo in humans, and the low biological plausibility of the effect observed in the human intervention study. The Panel concludes that a cause and effect relationship has not been established between the consumption of Symbiosal® and lowering of blood pressure. </p
