Progress in Variety Tests of Barley
The object of this bulletin is to report the progress of work which has been done in testing different varieties of barley. The variety trials of barley have been made in co-operation with Bureau of Plant Industry United States Department of Agriculture. During this time the work has been very extensive and man varieties have been tested. In the season of 1908, eighty-seven (87) varieties were grown at this Station. Before taking up the study of the different varieties, it may be of interest to note that the center of distribution has been westward. We cannot say definitely whether the distribution of barley in this country is due to soil conditions or not. We know that the general direction has been westward for the last fifty years but this can be attributed to the opening and settlement of heretofore unbroken country rather than to an acceptable environment. About the year 1850 the center of barley production was in the state of New York and it may be of interest to the people of South Dakota to know that now it has moved to a point near Sioux Falls

Alkali Soils
The continued demand for information concerning the distribution of alkali soils and proper methods of handling them have led this department to make these preliminary investigations. In coming in contact with farmers in the eastern portion of South Dakota, where there is an abundant supply of rain-fall, the question was asked many times, What shall we do with small areas where alkali is making its presence known by killing crops? It seems that the system of cultivation of the soil has induced such excessive evaporation that the salts have been left on the surface. It has also been observed that in places where these spots are small in size that they are growing larger. The popular term designates alkali soils, with reference to poorly drained areas where there is usually an accumulation of white or brownish white salt on the surface. These salts usually make their appearance during the latter part of the growing season, being, of course, influenced by the distribution of rain-fall. For convenience we may classify alkali salts under two groups, (1), soluble, (2), less soluble salts. The more common soluble salts consist of three chief ingredients, sodium chloride, (common salt); sulphate of soda, (Glauber\u27ssalt), and Sodium carbonate. They are all detrimental to plant growth, the latter being known as black alkali . The name, black alkali is very appropriate in that it produces black spots or puddles. This is because of the soluble effect of the sodium carbonate on humus. It hardly ever happens that only one of these salts is present but the three always seem to be associated. Commonly magnesium sulphate, potassium sulphate, sodium phosphate, and sodium nitrate are also present

Optical Spectroscopy of the Dusty K5 V Star HD 98800
High-resolution CCD spectra of the red region of the dusty K5 V star HD 98800, which may contain a protoplanetary disk, have been obtained at Kitt Peak National Observatory. The spectra verify the dwarf spectral type and show rotationally broadened photospheric lines, Hα emission, and a very strong Li Ι λ6707 absorption line, all of which confirm the star as a very young object. The overall spectrum of HD 98800 closely resembles that of the young, chromospherically active, single BY Dra star HD 82558 (=LQ Hya). The measured Li Ι equivalent width of 0.39 Å implies an abundance log N(Li) = 2.2 and suggests an age \u3c10 Myr. HD 98800 should be photometrically variable with a probable rotation period of 5-10 days. The high level of chromospheric activity suggests HD 98800 may be detectable as an X-ray and radio source
Comparison of College Student Hypertension Prevalence between the JNC7 and ACC/AHA Diagnostic Criteria
International Journal of Exercise Science 12(3): 898-903, 2019. Hypertension is highly prevalent and associated with non-communicable diseases and increased premature mortality risk. However, the impact of the new hypertension diagnostic criteria on the prevalence of hypertension diagnoses has yet to be examined among college students. The purpose of this study was to compare the prevalence of hypertension between the JNC7 and the ACC/AHA hypertension diagnostic criteria among college students. The blood pressure of 5,945 college students was assessed, and chi-square tests for independence examined differences between JNC7 and ACC/AHA criteria. The mean age of participants was 21.30 ± 1.05 years, and the majority identified as men (60.5%). Men were found to have significantly higher systolic (p \u3c .001, η2 = .10) and diastolic (p \u3c .001, η2 = .04) blood pressure, so all analyses were separated by sex. Hypertension guideline changes resulted in significant changes in hypertension categorization of both men, χ2 = 7,178, p \u3c .001, Фc = .816 and women, χ2 = 4,670, p \u3c .001, Фc = .816. Under the JNC7 guidelines, 292 (8.2%) men and 67 (2.8%) women were hypertensive. Using the ACC/AHA guidelines, 1455 (40.5%) men and 521 (22.3%) women were hypertensive. Hypertension guideline changes resulted in a significant increase in the prevalence of hypertension among college students, highlighting the potential demand for targeted prevention programs focused on fostering healthy lifestyle behaviors, i.e. physical activity and healthy eating, among students

Culture, risk factors and mortality: can Switzerland add missing pieces to the European puzzle?
BACKGROUND: The aim was to compare cause-specific mortality, self-rated health (SRH) and risk factors in the French and German part of Switzerland and to discuss to what extent variations between these regions reflect differences between France and Germany. METHODS: Data were used from the general population of German and French Switzerland with 2.8 million individuals aged 45-74 years, contributing 176 782 deaths between 1990 and 2000. Adjusted mortality risks were calculated from the Swiss National Cohort, a longitudinal census-based record linkage study. Results were contrasted with cross-sectional analyses of SRH and risk factors (Swiss Health Survey 1992/3) and with cross-sectional national and international mortality rates for 1980, 1990 and 2000. RESULTS: Despite similar all-cause mortality, there were substantial differences in cause-specific mortality between Swiss regions. Deaths from circulatory disease were more common in German Switzerland, while causes related to alcohol consumption were more prevalent in French Switzerland. Many but not all of the mortality differences between the two regions could be explained by variations in risk factors. Similar patterns were found between Germany and France. CONCLUSION: Characteristic mortality and behavioural differentials between the German- and the French-speaking parts of Switzerland could also be found between Germany and France. However, some of the international variations in mortality were not in line with the Swiss regional comparison nor with differences in risk factors. These could relate to peculiarities in assignment of cause of death. With its cultural diversity, Switzerland offers the opportunity to examine cultural determinants of mortality without bias due to different statistical systems or national health policies
