Assessing yield stability in African yam bean (Sphenostylis stenocarpa) performance using year effect

Abstract Maintaining yield stability in the African yam bean (AYB) (Sphenostylis stenocarpa) under year-to-year variability is crucial to its sustained productivity. Exploring yield stability in crops is vital in identifying how stable and consistent the yield of such crops is. Cultivation of AYB, an underutilized traditional legume in a specific environment, will further popularize the crop and enhance the acceptance as a cheap protein source thereby reducing hunger and malnutrition especially in regions where climate change has negatively affected legume crop production. Field trials were carried out to study the performance of 23 AYB genotypes in four-year environments. Two seeds of each genotype were sown in a single 5 m row plot spaced at 1 m between and within rows; the trial was conducted during the cropping season of 2011, 2012, 2013, and 2014 and was laid out in a randomized complete block design (RCBD) with three replications. At harvesting, five plants from each row were separately harvested; seeds of all the sampled plants in each plot were bulked and weighed, and the seed yield per plant was then determined. A combined analysis of variance (ANOVA) was performed to test for the significance of genotypes, year, and genotype by year interaction. Before combined ANOVA, a test for homogeneity of residual variances was performed using Bartlet’s test; stability of the genotypes over the years was ascertained numerically and graphically using additive main effects and multiplicative interaction and Genotype X Genotype X Environment interaction (GGE) biplot analyses. Rainfall distribution between 680 and 1,700 mm with an average temperature of 28.50°C under sandy-clay soil type supported high and stable seed yield production in AYB. This environment was found adequate during the 2014 (E1) growing season. Genotypes TSs118, TSs12, TSs109, TSs148, TSs5, TSs61, and TSs69 produced an above-average mean yield across the years and were found to be productive and stable in all the year environments. TSs82 and TSs6 with above-average mean seed and tuber yield can be considered for cultivation where seed and tuber dual-purpose production is to be maximized, while TSs111, TSs49, and TSs96 with high tuber yield ranking above average total tuber yield can be further enhanced for tuber production.

Comparing scale parameters in several gamma distributions with known shapes

In this paper, we present eleven approaches for testing the equality of scale parameters in gamma distributions when shape parameters are known. These approaches are applicable to other problems such as testing homogeneity of variances in normal distributions, verifying equality of scale-like parameters in inverse Gaussian distributions, and comparing scale parameters in two-parameter exponential distributions with censored data or K-record values. The performance of the proposed tests is compared in terms of empirical size and power using Monte Carlo simulation. Finally, the proposed methods are illustrated using two real data examples.

Specific influence of knowledge intensive and capital intensive organizations on collaborative climate and knowledge sharing in SMEs

In this paper, the authors discuss knowledge management, with a focus on knowledge sharing. Knowledge sharing is dependent on trust and cooperation, which are elements of organizational culture. One specific aspect of organizational culture is of particular interest for knowledge sharing. This aspect consists of values, beliefs and atmosphere that characterize common mental space accepted by knowledge workers which affect behavior and readiness to share knowledge. This aspect of organizational culture is called collaborative climate and can be described as the 'permeability' of the human infrastructure for knowledge sharing. Collaborative climate in an organization can be considered as an environment that provides support to knowledge workers to create new knowledge that will be translated into a value, which will become competitive advantage of an organization. A questionnaire for assessing two dimensions of the collaborative climate: Organizational Culture and Employee Attitude was used as an instrument in this research. The main research questions in this paper are: 1) Is there a statistically significant difference between attitudes towards collaborative climate of managers and employees? 2) Is there a statistically significant difference between attitudes towards collaborative climate in capital intensive and knowledge intensive organizations? Research hypotheses emerged from the main research questions. The survey was conducted in order to answer research questions. Data collection was carried out in 2016 throughout the territory of the Republic of Serbia. The sample in this research consisted of 114 managers from 78 randomly selected SMEs from the database of the National Agency for Regional Development. Afterwards, 647 employees were surveyed from those same companies, and in total 761 valid responses were collected. Principal component analysis was applied to the data. In order to check for statistically significant differences, factor scores were tested using Leven’s homogeneity test of variance and t-test. Data analysis indicated the existence of statistically significant differences between employee and managers attitudes in their assessment of collaborative climate in capital intensive and knowledge intensive organizations.

Ultrasound-Guided Percutaneous Release Procedures in the Lumbar Ligamentum Flavum by Acupotomy: A Cadaveric study.

Objective This study aims to determine the methods of percutaneous release procedures in the lumbar ligamentum flavum (LF) under ultrasound guidance by acupotomy and provide an anatomical basis for intrusive treatment of lumbar disc herniation and lumbar spinal canal stenosis. Methods Twelve cadavers including 4 females and 8 males aged 60 to 90 years (73.42 ± 14.57 years), without formalin fixation, were selected. Guided by an ultrasound transducer, we punctured acupotomy to release lumbar LF in L3/L4, L4/L5, and L5/S1 segments. In the transverse-axis approach, the probe was placed transversely, while in the longitudinal-axis approach, the probe was placed longitudinally. The depth of needle penetration (A), the distance between the puncture point and spinous process (B), and the distance between the puncture point and sacral cornu (C) were measured on cadavers, and the depth of needle penetration (U-A), the distance between the puncture point and spinous process (U-B), and the angle for acupotomy (D) on ultrasound images were also measured. Statistical analyses were carried out using SPSS. Paired sample t-tests and homogeneity of variance tests and one-way analysis of variance (ANOVA) were performed. The Pearson correlation coefficients and linear correlation coefficients were calculated for the data obtained from ultrasound and cadaver measurements. Results No obvious blood vessels and nerves were observed in the puncture path, and the spinal dura was intact. There was no statistical difference between the left and right side measurements obtained from the ultrasound images and the cadavers. The penetration depth in the transverse-axis approach was less than that in the longitudinal-axis approach, and the angle of the needle in the transverse-axis approach was greater than that in the longitudinal-axis approach. The measured data for the transverse-axis approach for L3/L4, L4/L5, and L5/S1 segments showed that there were no differences in the needle angle, the depth of needle penetration, and the distance from the spinous process to the puncture point among the three segments. There was a strong correlation between the depth of needle penetration and the distance from the spinous process to the puncture point on the ultrasonic images and the cadavers on the path of acupotomy. Linear equation A = 2.02 + 0.83 ∗ U-A, R2 = 0.352; B = 1.37 + 0.71 ∗ U-B, R2 = 0.252, where A/B refers to the data measured on the cadavers and U-A/U-B refers to the data measured on the ultrasound images. Conclusion In this study, ultrasound guidance was applied, which better guaranteed the safety and feasibility of acupotomy therapy. Before performing the treatment, the depth of needle penetration in the human body can be determined by measuring the distance between the needle point and the target position on the ultrasound image. Under ultrasound guidance, the transverse-axis approach has a smaller puncture depth and greater puncture angle than the longitudinal-axis approach. Hence, this study believes that the transverse-axis approach is safer for the clinical application of ultrasound-guided LF acupotomy lysis.

Computing the exact distribution of the Bartlett's test statistic by numerical inversion of its characteristic function

Application of the exact statistical inference frequently leads to non-standard probability distributions of the considered estimators or test statistics. The exact distributions of many estimators and test statistics can be specified by their characteristic functions, as is the case for the null distribution of the Bartlett's test statistic. However, analytical inversion of the characteristic function, if possible, frequently leads to complicated expressions for computing the distribution function and the corresponding quantiles. An efficient alternative is the well-known method based on numerical inversion of the characteristic functions, which is, however, ignored in popular statistical software packages. In this paper, we present the explicit characteristic function of the corrected Bartlett's test statistic together with the computationally fast and efficient implementation of the approach based on numerical inversion of this characteristic function, suggested for evaluating the exact null distribution used for testing homogeneity of variances in several normal populations, with possibly unequal sample sizes.

The Effect of Vitamin E Supplementation on Muscular Fatigue in Professional Men's Athletics

High-intensity exercise (3000-meter runner) contributes to muscle fatigue. Fatigue can be determined by measuring blood lactate levels. Blood lactate levels are a product of anaerobic metabolism. Lactate accumulation due to anaerobic physical activity can inhibit the glycolytic enzyme that affects decreased ATP production, damage of the calcium and sodium pumps in the muscles and causes fatigue. This study aimed to analyze the effect of vitamin E on the level of fatigue through the response of blood lactate levels in the runner 3000 meters. This research was a quasi-experimental research with a pretest-posttest design. Research subjects were 9 volunteer athletes (3000 meters runners) Aceh province, male, and aged 15-20 years. The treatments were vitamin E at a dose of 1x400 IU per day and administered for 14 days. Blood lactate levels were examined using the method of calorimetry. The statistical analysis was using the homogeneity test of variance (Levene's test), the normality test (Kolmogorov-Smirnov test) and paired t-test with a significant level of 5% (p-value<0.05). The results showed that blood lactate levels decreased approximately 13.93% after vitamin E supplementation. There was no significant difference (p=0.27) between blood lactate levels before and after vitamin E supplementation in athletes. In conclusion, vitamin E supplementation did not significantly lower blood lactate levels therefore vitamin E did not significantly reduce muscle fatigue in men's athletics.

Study on the correlation between small intestinal dendritic cells and non-alcoholic fatty liver disease in mice

Objective: To preliminary, explore the effect of small intestinal epithelial dendritic cells on the occurrence and development of nonalcoholic fatty liver disease in mice. Methods: Thirty-two (half male and half female) 4-week-old C57BL/6 mice were randomly divided into two groups. The mice were fed with normal diet (SD group) and high-fat diet (HFD group). Eight mice (half male and half female) were randomly killed from each group over the 14 and 20-weeks feeding period to observe their body weight, liver and small-intestine wet weight. Alanine aminotransferase, aspartate aminotransferase, blood glucose, high-density lipoprotein, low-density lipoprotein, total cholesterol and triglyceride were determined by eyeball blood samples. Pathological diagnosis and alcoholic fatty liver disease activity score were collected. The number of mice small intestinal dendritic cells was observed under a microscope. Statistical analysis was performed to compare two groups of independent samples with homogeneity test of variance, t test, and covariance analysis. Results: The body weight, liver wet weight, serum alanine aminotransferase and aspartate aminotransferase of mice in HFD group were significantly higher than those of control group at 20 weeks (P < 0.05), and the serum high density lipoprotein of mice in HFD group was significantly higher than that of SD group at 14 weeks (P < 0.05). At 14th weeks, the liver tissue of mice in HFD group had early pathological manifestations of hepatitis (fatty degeneration, punctate necrosis and balloon-like degeneration). Of which 87.5% (7/8) of them were diagnosed as non-alcoholic steatohepatitis or non-alcoholic fatty liver disease, while only a few mice in SD group had early pathological manifestations of hepatitis. At 20th weeks, all mice in HFD group were diagnosed with non-alcoholic steatohepatitis or non-alcoholic fatty liver disease, while none of the mice in SD group was diagnosed with non-alcoholic fatty liver disease. At both time points, the percentage of small intestinal dendritic cells in HFD group was significantly higher than that in SD group (14 weeks: 4.181 ± 4.314 vs. 15.099 ± 10.349; 20 weeks: 9.615 ± 8.267 vs. 32.839 ± 24.475, both P < 0.05). Statistical analysis combined with the alcoholic fatty liver disease activity score showed that there was no linear correlation between the two groups (regression coefficient was 20.196%). Conclusion: The number and different staging of small intestinal dendritic cells in mice is associated with the occurrence and development of NAFLD.
