Objective: Food insecurity in college students is associated with poor eating habits. The purpose of this project was to increase consumption of fruits and vegetables in college students using a campus food pantry. Participants: Twenty-nine college students completed the study. Methods: Participants viewed weekly food preparation videos demonstrating cost-effective recipes containing fruits and vegetables and a key take-away message. Participants were provided a recipe and food to cook at home based on the Cooking Matters Food Pantry Toolkit. A 24-h dietary recall was collected pre- and postintervention using the Automated Self-Administered 24-H Dietary Assessment. This descriptive comparative study used repeated measure ANOVA. Results: Females (n = 19) increased their fruit and vegetable consumption by 1.3 cups daily (p <.05) while males (n = 10) decreased fruit and vegetable consumption at the postintervention measurement. Conclusion: Increased consumption of fruits and vegetables in female college students using the food pantry was a modifiable behavior in this study. [ABSTRACT FROM AUTHOR]

In this study, we used three processes to synthesize magnesium sulfate from seawater. First, alkaline industrial wastes, cement kiln dust and paper sludge ash, were injected to the seawater to precipitate magnesium in the form of magnesium hydroxide (Mg(OH)2). Then, magnesium was eluted with a small amount of H2SO4 to make a high concentration magnesium solution. Finally, an organic solvent was added to precipitate magnesium sulfate (MgSO4). Over 90% of magnesium was recovered through the three processes. It is expected that 11.3 kg of magnesium sulfate (based on MgSO4 · 6H2O) can be synthesized from 1 ton of seawater.

Background:Poor sleep among college students is a major, growing problem associated with lower academic performance, higher rates of health and emotional problems, and development of chronic sleep disorders.Purpose:Though previous studies have focused on individual colleges, our study purpose was to reveal the association of behaviors and function to sleep quality in a large sample of students from across the United States.Methods:We analyzed data from the Fall 2009 American College Health Association's National College Health Assessment–II survey using descriptive statistics, independent samplettests, chi-square tests, and logistic regression to find a representative, matched sample of 14 870 college students, both with and without a sleep problem, measured by daytime sleepiness.Results:Our correlational analysis revealed that sleep quality decreased with increasing levels of stress or alcohol/cigarette use and with decreasing levels of general health (allPs < .001).Discussion:College interventions should include efforts to address sleep quality to improve students' academic performance and long-term quality of life, especially for students experiencing substantial stress or poor general health.Translation to Health Education Practice:Educators, advisors, and leaders should incorporate sleep quality improvements into their services and programs for all students, especially students in at-risk groups.

AMP-activated protein kinase (AMPK) is a key regulator of fatty acid biosynthesis and fatty acid oxidation throughout the body. Piperlongumine (PL) isolated fromPiper longum(L.) was shown to potently upregulate activation of AMPK via phosphorylation and inactivation of acetyl-CoA carboxylases in cultured HepG2 cells, presumably enhancing the transfer of fatty acids into mitochondrial cells by inhibiting malonyl-CoA production. PL showed cytotoxicity on HepG2 cell growth at the concentration of 5 μM of PL, while more than 80% of HepG2 cells were survived at the concentration of 2 μM of PL. Overall, the results of this study indicate that PL activates AMPK phosphorylation and possesses cytotoxicity in HepG2 cells. [ABSTRACT FROM PUBLISHER]

In this study, the soil washing technique has been used to treat mine tailings contaminated heavily with arsenic and heavy metals at Jingok mine, which is one of the abandoned mines in Korea. The results showed that phosphoric acid, citric acid, oxalic acid, and sodium metabisulfite were highly effective in extracting arsenic and heavy metals. Among them, oxalic acid was the most effective (especially for Pb, Cu, and Zn), as even a residual fraction of arsenic was partly extracted. The optimum concentration of washing reagent and the ratio between the mine tailings and washing reagent were found to be 0.5 M and 1:20, respectively. In addition, the extraction kinetics of arsenic and heavy metals was fast, in which the reaction time of 30 minutes was deemed to be a sufficient contact time. From the results, it may be concluded that the low pH of washing solution and the amount of dissolved Fe may be considered as the most important factors in the extraction of arsenic and heavy metals.

Monte Carlo simulations have been used extensively in studying the performance of control charts. Researchers have used various numbers of replications in their studies, but almost none of them provided justifications for the number of replications used. Currently, there are no empirically based recommendations regarding the required number of replications to ensure accurate results. This research examined six recently published studies to develop recommendations for the minimum number of replications necessary to reproduce the reported results within a specified degree of accuracy. The results of this study indicated that using 10,000 replications was unnecessarily large and a smaller number of replications could be used to reproduce the target ARLs within the 2% error bands satisfying the modified Mundfrom's criteria. In many cases, only 5,000 replications or fewer were required. In general, the number of replications required to reproduce the target ARL decreased as the shift size increased. In addition, the results of this study provide general recommendations for the required number of replications to use in future SPC simulation studies. [ABSTRACT FROM AUTHOR]
