We consider a three-point boundary value problem for operators such as the one-dimensional p-Laplacian, and show when they have solutions or not, and how many. The inverse operators are given by various formulas involving zeros of a real-valued function. They are shown to be orderpreserving, for some parameter values, and non-singleton valued for others. The operators are shown to be m-dissipative in the space of continuous functions.

In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, NE, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for 17, 32, and 28 d in 2005, 2006, and 2007, respectively. In 2005, average daily gain (AdG) for steers grazing triticale exceeded the AdG for wheat by 0.31 kghd-1d-1. In 2006, wheat AdG exceeded that for triticale by 0.12 kghd-1d-1. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained 0.20 kghd-1d-1. Based on the 3-year average animal gains valued at $1.32 kg-1, mean net return ($ ha-1 yr-1) was $62.15 for triticale and $22.55 for wheat. Since these grazed cover crops provide ecosystem services in addition to forage, grazing could be viewed as a mechanism for recovering costs and adds additional value to the system. Based on this 3-year grazing trial, triticale was superior to wheat and likely will provide the most stable beef yearling performance across years with variable weather for the western Cornbelt USA.

Objective: The prevalence of sport-related concussion(SRC) is high and results in a number of serious health consequences. One area that has received minimal research is the relationship between SRC and sleep. The literature shows that sleep deficiency is a frequent negative consequence of SRC. At the same time, sleep deficiency delays recovery from SRC and contributes added risk of symptom recurrence.A 2014 study of chronic pain patients who learned to apply the complementary and alternative medicine intervention hand self-shiatsu(HSS) had promising, sleep-promoting results that warrant further investigation with other populations. This proof-of-concept study explored the feasibility of HSS as an intervention to promote sleep onset and continuity for young adults with ***: This study employed a prospective case-series design, where participants act as their own controls. Baseline and follow-up data included standardized self-reported assessment tools and sleep ***: Seven athletes, aged between 18 and 25 years, participated in the study. Although statistically significant improvement in actigraphy sleep scores between baseline and follow-up was not achieved,metrics for sleep quality and daytime fatigue showed significant ***: These findings support the hypothesis that HSS has the potential to improve sleep and reduce daytime fatigue in young postconcussion athletes. This pilot study provides guidance to refine research protocols and lays a foundation for further, large-sample, controlled studies.
