In Japan, many food poisoning cases occur every year form the rainy season to summer. After all, restaurants account for about 50% of all food poisoning cases. Still they also occur at school meals (6.4%) and hospitals (0.6%), where hygiene management should strictly controlled in the Ministry of Health, Labor, and Welfare announced (2019). Therefore, from the viewpoint of food poisoning prevention, this study focused on the stove knob and water faucet, which are often touched by the cook’s fingers in the kitchen and may cause secondary contamination. The effect of hygiene education investigated by measuring invisible microbial load as visible ATP value using ATP wiping test. The 12 stove knob and 11 water faucet inspected before and after hygiene education by using the ATP wiping test. Before hygiene education, the average value of the ATP values measured after washing before and after washing. To the surprise, after washing, the ATP value did not drop below 1000 for Stove knob and Water faucet. Almost the same ATP value as before cleaning.

Since bacteria grow in high temperature and high humidity, bacterial food poisoning frequently occurs from the rainy season to summer. In Japan, the number of food poisoning cases is high from June to October. Maintaining a hygienic environment in the kitchen is very important for preventing food poisoning. In particular, cutting boards on which various foods are places may cause secondary pollution. Therefore, to avoid food poisoning, this study compared the ATP value of the cutting board before and after the hygiene education using the ATP wiping test and investigated the educational effect. Before hygiene education, the inspector conducted an ATP wiping test on the cutting boards for vegetables and meat that washed before and after cooking and notified the cooks of the values. The inspector conducted hygiene education while showing the cook how to clean the cutting board. The cutting board washed with detergent and sponge, rinsed with running water for 30 seconds or more, then this process was repeated twice.

In Japan, the number of food poisoning cases and the number of patients have been gradually decreasing in the last ten years. However, from the Japanese Ministry of Health, Labor and Welfare, the number of bacterial food poisoning cases has been approximately 41% of the total number in the past five years, which is still high. Therefore, in this study, to prevent food poisoning, we conducted hygiene education using the ATP test and confirmed the educational effect by comparing before and after education. ATP luminescence kit (Lumitester PD-10, LuciPac Pen) manufactured by Kikkoman Corporation used for the microbiological test. Before the hygiene education, the ATP of the knife handle, and the ATP of the knife blade measured before and after cooking. Twelve knives for vegetables and 12 knives for meat targeted. Before the hygiene education, the handle and the blade of the meat knife measured of ATP, that before cooking and washed after cooking. Further, the handle and blade of the kitchen knife for vegetables were also measured for ATP in the same manner as the knife for meat.

ABSTRACT By means of chromatographic and spectrophotometric methods progesterone and a substance closely similar to 20β-hydroxy-pregn-4-ene-3-one has been detected in luteal tissue from non-pregnant and pregnant cows. In 21 animals quantitative measurements based on a method giving an average net recovery of 56 per cent showed that in pregnancy the average progesterone content in the corpus luteum reached a maximum in the third to fifth month, with low values before and after this period. For 6 nonpregnant cows, the average value was 20.2 μg/g tissue, which is considerably higher than previous values reported in the literature. The relation between these findings and the bovine dependence on a functional corpus luteum in pregnancy is discussed, and it is pointed out that more information about the metabolism of progesterone in cattle is highly desirable.

Abstract Background The government investments in quality primary healthcare are the basis to strengthening the health systems and monitoring the public expenditure in this area is a way to assess the effectiveness and efficiency of the public health policies. The Brazil Ministry of Health changed, in 2017, the method of onlending federal resources to states and cities seeking to make the public funds management more flexible. This change, however, suppressed mandatory investments in primary healthcare. This research aims to determine the difference of expenditures on primary healthcare in Salvador, Bahia, Brazil metropolitan area before and after this funding reform, seeking to verify how it can impact the quality of primary healthcare services and programs. Methods This is an ecological time-series study that used data obtained in the Brazil Ministry of Health budget reports. The median and interquartile range of expenditures on primary healthcare (set as the percentage of total public health budget applied in primary care services and programs) of the 13 cities in the Salvador metropolitan area were compared two years before and after the reform. Results The median of expenditures on primary healthcare in Salvador metropolitan area was 25.5% (13,9% - 32,2%) of total public health budget before and 24.8% (20.8% - 30.0%) of total public health budget after the reform (-0.7% difference). Seven cities decreased the expenditures on primary healthcare after the reform, ranging from 1.2% to 10.8% reduction in the primary healthcare budget in five years. Conclusions Expenditures on primary healthcare in Salvador metropolitan area decreased after the 2017 funding reform. Seven of 13 cities reduced the government investments on primary healthcare services and programs in this scenario. Although the overall difference was -0.7%, the budget cuts ranged from 1.2% to 10.8% in the analyzed period and sample. More studies should assess these events in wide areas and with long time ranges. Key messages Public health funding models can impact the primary healthcare settings regardless of the health policy. Reforms in the funding models should consider the possible benefits before implementation. Funding models and methods that require mandatory investments in primary healthcare may be considered over more flexible ones.

A previous study has used the stable and peculiar echoes backscattered by a single “bright scatterer” (BS) during five winter days to characterize the hardware of C-band, the dual-polarization radar located at Monte Lema (1625 m altitude) in Southern Switzerland. The BS is the 90 m tall metallic tower on Cimetta (1633 m altitude, 18 km range). In this note, the statistics of the echoes from the BS were derived from other ten dry days with normal propagation conditions in winter 2015 and January 2019. The study confirms that spectral signatures, such as spectrum width, wideband noise and Doppler velocity, were persistently stable. Regarding the polarimetric signatures, the large values (with small dispersion) of the copolar correlation coefficient between horizontal and vertical polarization were also confirmed: the average value was 0.9961 (0.9982) in winter 2015 (January 2019); the daily standard deviations were very small, ranging from 0.0007 to 0.0030. The dispersion of the differential phase shift was also confirmed to be quite small: the daily standard deviation ranged from a minimum of 2.5° to a maximum of 5.3°. Radar reflectivities in both polarizations were typically around 80 dBz and were confirmed to be among the largest values observed in the surveillance volume of the Monte Lema radar. Finally, another recent 5-day data set from January 2020 was analyzed after the replacement of the radar calibration unit that includes low noise amplifiers: these five days show poorer characteristics of the polarimetric signatures and a few outliers affecting the spectral signatures. It was shown that the “historical” polarimetric and spectral signatures of a bright scatterer could represent a benchmark for an in-depth comparison after hardware replacements.

Исследована кинетика сушки сырой пивной дробины – вторичного продукта ООО «Белореченский пивоваренный завод» (Россия, Краснодарский край). Сушка проведена в двух температурных режимах – 60 и 55°С. Скорость сушильного агента при вынужденной конвекции составляла 4,5 м/с. Содержание сухого вещества определено по ГОСТ 31640–2012 в лабораторных условиях и составило 12,9%. Измерение убыли массы при сушке проведено с интервалом 5 мин. Общее время сушки навески пивной дробины в количестве 50 г – 420 мин при режиме 50°С, 360 мин – при 60°С. Среднее значение конечной влажности пивной дробины составило 11,85%. Построены кривые сушки и скорости сушки. Скорость сушки при удалении свободной влаги в первом периоде сушки, мин–1: при 60°С – 3,5, при 55°С – 3,0. Установлено, что содержание связанной влаги составляет в среднем 57% от массы влаги в навеске пивной дробины, свободной влаги – 43%. Анализ структуры навески пивной дробины под микроскопом до сушки и после нее подтвердил факт, что в исследованном материале количество связанной влаги больше, чем свободной. Наличие частиц размером 5–7 мм свидетельствует о значительном количестве клеточной влаги в неразрушенных капиллярах. Дальнейшее совершенствование технологии переработки пивной дробины должно быть направлено на разрушение клеточной структуры материала после его механического обезвоживания. The kinetics of drying of the crude brewer’s spent grain – a secondary product of LLC «Belorechensky brewery» (Russian Federation, Krasnodarregion) has been studied. Drying is carried out in two temperature modes – 60 and 55°C. The speed of the drying agent under forced convection was 4,5 m/s. The dry matter content was determined according to GOST 31640–2012 in laboratory conditions and was 12,9%. Measurement of mass loss during drying was performed at an interval of 5 min. The total drying time of the brewer’s spent grain sample in the amount of 50 gis 420 min at 50°C, 360 min – at 60°C. The average value of the final moisture content of brewer’s spent grain made up 11,85%. Curves of drying and drying speed are constructed. Drying speed when removing free moisture in the first drying period, min–1: at 60°C – 3,5, at 55°C – 3,0. It was found that the content on average of bound moisture is 57% of the mass of moisture in brewer’s spent grain, free moisture – 43%. Analysis of the structure sample of brewer’s spent grain a microscope before and after drying confirmed the fact that the amount of bound moisture in the studied material is greater than the amount of free moisture. The presence of particles of 5–7 mm in size indicates a significant amount of cellular moisture in undisturbed capillaries. Further improvement of the technology for processing brewer’s spent grain should be aimed at destroying the cellular structure of the material after its mechanical dehydration.

It is shown that the replacement of a part of sulfur atoms with selenium atoms in a TlInS2 single crystal stimulates the formation of a single-phase state with a monoclinic structure (space group [Formula: see text]/[Formula: see text] in TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]). Irradiation with 2 MeV electrons and a fluence of [Formula: see text] electron/cm2 of powder TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]) leads to an increase in the crystallite size from 56.5 nm to 65 nm, which is most likely associated with a decrease in the interface. The difference between the surface morphology of the synthesized TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]) single crystal and the surface morphology of the TlInS2 single crystal is established, which consists in a decrease in the height and width of the roughness in TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]). Irradiation of a TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]) single crystal with electrons with a fluence of [Formula: see text] electron/cm2 does not lead to a change in the height of the tubercle on its surface, and the average value of its width increases more than ten-fold. The identity of the peaks in the Raman spectra of the TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]) single crystal before and after its irradiation with electrons with an energy of 2 MeV and upto a fluence of [Formula: see text] electron/cm2, along with the absence of a shift of the peaks, indicates the radiation resistance of the TlInS[Formula: see text]Se[Formula: see text] ([Formula: see text]) single crystal.
