The therapeutic properties of Lactobacillus rhamnosus GR-1 and ginseng extracts have been well documented. The objective of this study was to measure growth and survival of L. rhamnosus GR-1 in milk fortified with ginseng extracts during storage period of 28 days. Five formulations of milk (1% fat) were prepared. Two samples were fortified with alcoholic ginseng extract (AGE: 150 μg/mL, AGE: 500 μg/mL) and the other two samples were fortified with aqueous ginseng extract (QGE: 150 μg/mL, QGE: 500 μg/ml) and one with no ginseng extract (C). The mixtures were autoclaved for 15 min, cooled to 37?C and inoculated with 1% starter culture. The samples were then incubated anaerobically at 37℃ overnight. Selective MRS agar containing 0.015 g/L fusidic acid was used to enumerate L. rhamnosus GR-1 after 1, 14, and 28 d storage at 4℃. All ginseng-fortified samples supported the growth and survival of L. rhamnosus GR-1, as viable counts were detected at each measurement point throughout the 28 d storage period. After 1 d of storage, total colony counts for L. rhamnosus GR-1 in AGE: 150 μg/mL and AGE: 500 μg/mL were 1.3 × 109 and 1.4 × 109 CFU/mL, respectively;probiotic counts in QGE 150 μg/mL and QGE: 500 μg/mL were 1.5 × 109 and 1.4 × 109 CFU/mL, respectively. Additionally, L. rhamnosus GR-1 viability remained stable throughout the 28 days storage period, as no significant decrease (p L. rhamnosus GR-1 can remain viable in presence of ginseng extracts during storage period and there is potential for incorporating ginseng extracts in other probiotic dairy products.

We fabricate a free-standing few-layer molybdenum disulfide （MoS2）-polymer composite by liquid phase exfoliation of chemically pristine MoS2 crystals and use this to demonstrate a wideband tunable, ultrafast mode-locked fiber laser. Stable, picosecond pulses, tunable from 1,535 nm to 1,565 nm, are generated, corresponding to photon energies below the MoS2 material bandgap. These results contribute to the growing body of work studying the nonlinear optical properties of transition metal dichalcogenides that present new opportunities for ultrafast photonic applications.

Zika virus disease is a disease of public health importance and was declared a “Public Health Emergency of International Concern”, by the World Health Organization on February 1, 2016. It is mostly transmitted through the bite of Aedes aegypti and Aedes albopictus mosquitos. Transmission can also occur through blood transfusion and sexual intercourse. It could cause microcephaly and other neurological problems in newborns and adults, such as Guillain-Barre syndrome. It could also lead to abortion and stillbirth in pregnant women. Prevention methods are essentially targeted at transmission routes, which are mosquito bite, sexual intercourse, and blood transfusion. The study was of observational, descriptive, cross-sectional design, and conducted in a tertiary health institution in the Southeast geopolitical zone of Nigeria. Two hundred and fifty-six female caregivers participated in the study, with most of them being within the childbearing age group, and educated up to tertiary level. The objective was to assess the knowledge of Zika virus infection prevention methods, among female caregivers that bring babies for immunization in a Teaching Hospital, Southeast Nigeria. Out of the eight questions that sought to assess the knowledge level of the respondents, they scored 50% and above only in three, which were on prevention through protection against mosquito bite (60.5%), avoiding unnecessary blood transfusion in endemic areas (53.9%), and avoidance of oily meals not being a preventive measure (51.2%). Respondents in the childbearing age group, and those with higher educational qualifications, generally exhibited higher knowledge level than the other respondents. Scores on questions that sought to assess their knowledge on prevention aspects related to sexual behavior, and vaccination were poor. Sensitization, or awareness creation activities for persons in this study area, ought to be designed to address the observed gaps.

The long-term climate datasets are widely used in a variety of climate analyses. These datasets, however, have been adversely impacted by inhomogeneities caused by, for example relocations of meteorological station, change of land use cover surrounding the weather stations, substitution of meteorological station, changes of shelters, changes of instrumentation due to its failure or damage, and change of observation hours. If these inhomogeneities are not detected and adjusted properly, the results of climate analyses using these data can be erroneous. In this paper for the first time, monthly mean air temperatures of the United Republic of Tanzania are homogenized by using HOMER software package. This software is one of the most recent homogenization software and exhibited the best results in the comparative analysis performed within the COST Action ES0601 (HOME). Monthly mean minimum (TN) and maximum (TX) air temperatures from 1974 to 2012 were used in the analysis. These datasets were obtained from Tanzania Meteorological Agency (TMA). The analysis reveals a larger number of artificial break points in TX (12 breaks) than TN (5 breaks) time series. The homogenization process was assessed by comparing results obtained with Correlation analysis and Principal Component analysis (PCA) of homogenized and non-homogenized datasets. Mann-Kendal non-parametric test was used to estimate the existence, magnitude and statistical significance of potential trends in the homogenized and non-homogenized time series. Correlation analysis reveals stronger correlation in homogenized TX than TN in relation to non-homogenized time series. Results from PCA suggest that the explained variances of the principal components are higher in homogenized TX than TN in relation to non-homogenized time series. Mann-Kendal non-parametric test reveals that the number of statistical significant trend increases higher with homogenized TX (96%) than TN (67%) in relation to non-homogenized datasets.

The generalized constitutive model relating the resilient modulus (MR) of flexible pavement layer materials to stress state, adopted by the Mechanistic-Empirical Pavement Design Guide (MEPDG), contains a set of constants known as k-values (k1, k2, and k3) which are associated with the physical state of the layer materials. In Ghana, natural gravels constitute the predominant and sometimes the sole layer materials for most flexible pavements yet representative k-values of gravel materials, have not been determined to permit full application and implementation of the mechanistic-empirical design concept to pavements involving such materials. In this study, k-values characterising typical natural quartzitic gravels used for road construction in the country were derived by regression techniques from MR values determined using laboratory repeated load triaxial test. Using multiple linear regression technique, correlation relationships were then developed between the k-values and the physical properties of the gravels, namely, percentages of materials passing the 9.5 mm (P9.5) and 2.0 mm (P2.0) sieves, liquid limit (LL), maximum dry density (ρdmax), and optimum moisture content (wopt). The regression analysis returned k1 values which ranged between 441 and 958 with a mean of 516;k2 which varied between 0.0636 and 0.2168 with a mean value of 0.1216;and, k3 values which ranged between 0.1257 and 3.1590 with a mean value of 1.723. Contrary to what is mostly reported in literature, the analysis returned positive k3 values for all but one gravel material, suggesting stress hardening under octahedral shear stress for those materials. While an expanded sample base is required to fully characterize the whole gamut of natural gravels used in pavement construction in the country, this study on limited quartzitic gravel samples has given a good indication of strong linear correlations between the k-values and the index properties of the gravels, to permit estimates of the constants
