Tracking the influence of service improvements on passengers particularly is an important component of transport management. This study examined the characteristics of intercity travellers in the Economy Class Units (ECU) and recently introduced Diesel Multiple Unit (DMU) service within the Lagos District Nigeria Railway Corporation in southwestern Nigeria. A structured questionnaire was randomly administered to 1206 passengers traveling on these trains over two months with analysis in-volving the use of the regression model. The findings of the study indicate the socio-economic characteristics of passengers accounted for about 90.3% and 88.2% of the variation in volume trips made by passengers using DMU and ECU service respectively. Significant socio-economic predictors of trip volume on DMU train are Occupation (0.137), Vehicle Ownership (0.218), and Type of vehicle (0.218). On the other hand, significant socio-economic attributes of ECU passengers that affect trip volume are Age (0.274), Education (0.970), Occupation (-0.918), Income (0.435), Vehicle Ownership (0.249), and type of Vehicle (-0.165). The result further indicates Trip Purpose explained 83.5% and 86.7% of the variation in the trip volume of both services. The trip purpose that significantly influences the volume of trips on the ECU trains are Business (0.210), Shopping (0.447) Leisure (-0.463), and other trip purposes (0.775). For the DMU train, only Other-trip forms of purpose (0.753) is significant in explaining the volume of passengers using that service. The study shows similarities in the use of the two services while several useful recommendations on ways to improve both services of the corporation were proffered.

This study aimed to inventory, identify, characterize and valorize the various edible non wood forest products (NWFPs) sold in Uíge Province. Data for this study were collected between October 2016 and February 2020. A total of 156 edible NWFPs sellers were individually interviewed using semi-structured questionnaire at the 30 sales sites. 93.5% of edible NWFP sellers were female and 6.5% male. The main edible NWFPs sold in Uíge Province are animal products with 47 species, of which 48.9% are Mammals, 21.3% Insects, 12.8% Actinopterygii, 6.4% Birds, 8.5% Reptiles, and 2.1% Sarcopterygii. Plants represent 38.5% (35 species) of the edible NWFPs sold in the study area, of which 78.8% are Dicotyledones, 21.2% Monocotyledones, 2.9% Gnetophytes and 2.9% Pteridophytes. Besides, Mushrooms account for barely 9.9% of the edible NWFPs sold in this region. On the other hand, edible NWFPs are sold on formal and informal markets, in the bus parking lots, taxi runk, roadsides, restaurants and at the seller’ homes. For the sale of edible forest products, the vendors use non-standardized measuring units. The income generated by the sale of NWFPs is used to solve socio-economic problems in the household, including the purchase of basic necessities, health care, clothing, cosmetics, school materials, well-being, etc.

This paper summarizes the results of a study that explains the impact of minimarkets existence on the sales turnover of traditional shops in Ciledug Subdistrict, Cirebon Regency in 2017, West Java, Indonesia. Through a statistical method - called the difference test - the existence of minimarkets in Ciledug Subdistrict has significantly reduced the sales turnover and reduced the number of buyers of the traditional shops, on the other hand the number of working hours of traditional shops has increased. This study also uses the regression model to explain the effect of the number of buyers, traditional shops’ working hours, and the distance between traditional shops to the nearest minimarkets on the sales turnover of traditional shops. This study shows that all independent variables simultaneously significant affected on the sales turnover of traditional shops. Partially, the number of buyers and the distances between traditional shops to the nearest minimarkets significantly influence the sales turnover of traditional shops, but the working hours of the traditional shops does not has a significant effect.

Background and objective: Hypertension is a multifactorial disease where numerous constitutive, genetic and environmental factors interplay. Among the constitutive factors, age is a major determent continuously reported to be associated with a significant increase in the prevalence of hypertension. In addition to age, Helicobacter pylori (H. pylori) infection was also shown to be associated. On the other hand, Vitamin D (Vit D) plays an important role against the development of hypertension. In the current study, we investigated whether H. pylori interacts with Vit D levels to influence hypertension. Methods: This cross-sectional study was conducted on seven hundred eighty-two “a priori” healthy individuals equally divided according to hypertension status. To study the association between Vit D, H. pylori and hypertension, a multivariate logistic regression model was used while correcting for different confounding factors. Power analysis was also performed. Results: Approximately half of the participants were hypertensive and had Vit D insufficiency, they were also matched for age. Using a multiple logistic regression model, our results showed an inversely proportionate association between H. pylori infection and the risk of hypertension (OR=0.37, P<0.001). On the other hand, a proportionate association between Vit D deficiency and hypertension was observed (OR=2.76, P=0.004). Furthermore, Vit D and H. pylori status interacted to affect the risk of hypertension (OR=0.973, P=0.004). Stratification according to Vit D status showed that 59.1% of Vit D deficient participants were infected with H. pylori organisms (P<0.001). When taking hypertension, Vit D, and H. pylori statuses into account, we found that the prevalence of hypertension was doubled when the participants were negative for H. pylori infection but had Vit D deficiency (P<0.001). Conclusion: H. pylori infection and Vit D deficiency could predict hypertension. The odds of hypertension development were double when the participants were negative for H. pylori infection and had vitamin D deficiency.

In cricket, irrespective of the format of the game, batting always happens in pairs. The two batsmen who bat together are called as batting partners. The pair of batsmen who come to bat at the beginning of any innings are called opening batsmen or opening partners. In Twenty20 cricket, the opening partners must start their innings with a definite strategy. In one hand, they have the advantage of only two fielders outside the 30-yard circle for the first six overs (technically called as the powerplay overs), and so both openers are expected to play high scoring shots and attempt to score runs quickly. On the other hand, the odds against them are the ball is new, so is the pitch and the bowlers are fresh and energetic. When any one of the opening batsmen loses his wicket, the partnership comes to an end. This study tries to figure out the influence of the opening partnership of the second innings on the outcome of Twenty20 matches. Pressure Index (developed by earlier researchers), effects of venue or ground and target score are used as explanatory variables in the logistic regression model to check if the performance of opening partnership influences the outcome of Twenty20 matches along with other variables. The data used for the exercise is from Twenty20 international cricket matches played within the period January 2012 to June 2018. The study finds that opening partnership while chasing is a significant factor in deciding the match outcome during the run chase for the said dataset. Also, the best opening batting partners have been identified.

AbstractThe study reviews the evidence presented in a recent study linking vitamin D levels and Covid-19 infection and mortality. It was argued that correlation alone may not be useful in establishing a relationship between vitamin D levels and Covid-19 infections and mortality. Appropriate controls need to be included for improved understanding of the relationship. We proposed life expectancy as a potential control. Including this control in a regression model, we find that vitamin D levels are not a statistically significant predictor of Covid-19 infections or mortality. Life expectancy, on the other hand, was found to be statistically significant predictor of infections and mortality at country level.

AbstractWe have developed a model for theH2OandOHevolution in a comet outburst, assuming that together with the gas, a distribution of icy grains is ejected. With an initial mass of icy grains of 108kg released, theH2OandOHproductions are increased up to a factor two, and the growth curves change drastically in the first two days. The model is applied to eruptions detected in theOHradio monitorings and fits well with the slow variations in the flux. On the other hand, several events of short duration appear, consisting of a sudden rise ofOHflux, followed by a sudden decay on the second day. These apparent short bursts are frequently found as precursors of a more durable eruption. We suggest that both of them are part of a unique eruption, and that the sudden decay is due to collisions that de-excite theOHmaser, when it reaches the Cometopause region located at 1.35 × 105kmfrom the nucleus.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.
