AbstractObjectiveThe purpose of this meta analysis was to assess the correlation between CDKAL1 rs10946398C>A single nucleotide polymorphism (SNP) and type 2 diabetes mellitus (T2DM) susceptibility by pooling the open published studies.MethodElectronic searching of PubMed, EMBASE, Medline, Cochrane, China Biology Medicine disc (CBM) and China National Knowledge Infrastructure (CNKI) databases were performed by two reviewers independently to collect the open published studies related to CDKAL1 rs10946398C>A single nucleotide polymorphism and T2DM susceptibility. The association between CDKAL1 rs10946398C>A single nucleotide polymorphism and T2DM susceptibility was expressed by odds ratio (OR) and the corresponding 95% confidence interval (95%CI).ResultsThirteen studies with a total of 13,966 T2DM and 14,274 controls were finally included for analysis in this meta-analysis. Of the included 13 publications, 2 studies were carried out in Europe, 8 in Asia, 2 in Africa and 1 in Latin America. Being significant statistical heterogeneity, the data was pooled through random effect model. In a dominant genetic model, there was significant correlation between CDKAL1 rs10946398C>A SNP and T2DM risk (OR=1.22, P<0.05). In a dominant genetic model people with CC or CA genotype had increased risk of developing T2DM; Because of statistical heterogeneity for the included studies in a recessive genetic model (AA+CA vs CC), the data was calculated by random effect method. The combined data showed people with AA or CA genotype had decreased risk of developing T2DM compared to CC genotype (OR=0.83, P<0.05); For a homozygous genetic model (CC vs AA), the OR was calculated through random effect model for statistical heterogeneity among the included 13 studies. The combined OR was 1.33 which indicated people with CC genotype had increased risk of developing T2DM.ConclusionAccording to the present results, CDKAL1 rs10946398C>A single nucleotide polymorphism had correlation with the susceptibility of type 2 diabetes mellitus.

SUMMARYGenetic diversity was assessed in 46 non-oilseed sunflower genotypes for 14 characters by adopting D2 analysis. Oil content and plant height exhibited maximum contributions towards genetic divergence. The genotypes were grouped into 11 clusters. The inter-cluster D2 values ranged from 288.17 to 3972.34. The contribution of oil content towards genetic divergence in the 46 genotypes was confirmed when D2 analysis was performed for seed characteristics such as test weight, volume weight, hull content, kernel recovery, oil and protein content.

SUMMARYIn arid and semi arid areas, water is the most limiting factor of crop production. Germination is susceptible to water shortage. Experimentation was undertaken to study the effect of water stress on germination of seeds of three sunflower genotypes (Oro 9, Mirasol and Albena). Six PEG 6000 osmotic constraints were tested (0, -0.4, -0.6, -1, -1.2 and -1.6 MPa). Results showed no significant difference between germination percent of the control and -0.4 MPa treatment and between -0.8, -1 and -1.2 MPa treatments. Germination percent was most reduced at -1.6 MPa (-65%). Mean germination duration was also affected and the highest value was obtained for -1.6 MPa (4.95 days, related to an increase of 185%). Differences between genotypes were significant in the treatment at -1 MPa.

SUMMARYSix cytoplasmic male sterile lines used as females were crossed with four fertile lines used as males in a factorial design. The 24 F1 hybrids obtained were evaluated in vitro for their organogenesis ability from cotyledonary explants. The regeneration medium was MS supplemented with 200 mg/l of glutamine, 1 mg/l of indol-3-acetic acid and 2 mg/l of kinetin. The experimental design was a complete randomized block in 2 replications. General combining ability variances were significant for some of the in vitro traits, while the variance due to specific combining ability was nonsignificant in all cases. Some of these positive and negative values of general combining ability were significant for the studied traits. These results suggest the importance of the additive component in the genetic control of the studied in vitro traits.

SUMMARYThe objective of this paper was to estimate the genetic and ecological variation as well as the stability of tuber yield per plant, tuber number per plant and tuber size of Jerusalem artichoke based on the results of a variety trial carried out with 20 different Jerusalem artichoke varieties during the period of 1994-2000. Significant genetic as well as ecologycal variation was observed for all of the traits studied. The most promissing varieties showing high tuber yield combined with high yield stability were “BT-4”, “Violet Rennes” and “UKR 4/ 82”. It is encouraging that the highest yielding varieties exibited a rather stable performance over environments.

SUMMARYIn this study, mitotic effects of gamma rays on Ekiz 1 variety belonging to Helianthus annuus L. (2n= 34) in the M0 (first irradiated seeds), M1 and M2 generations have been investigated. Seeds (M0) were irradiated with gamma rays at 10, 20, 30, 40 and 50 kR doses. Percentage of total abnormalities in the M0, M1 and M2 generations increased parallel to the increasing dose of radiation. These abnormalites have been observed as C-metaphase, chromosome stickiness, laggards and bridges with or without fragment. Mitotic index (M.I.) in the M0, M1 and M2 generations has decreased parallel to the dose increase. When the generations are compared, both the amounts of decrease in mitotic index and in the percentage of mitotic abnormalities were mostly observed in M0.

SUMMARYFive fungicides, namely Tecto, Benlate, Bayton, Topsin and Derosal, were evaluated for their effect on seed germination and control of major seed-borne pathogens of sunflower. Two sunflower cultivars, HO-1 and NK-212, naturally infected with important seed-borne fungi were treated with these fungicides at 1.5, 2.0, 2.5, 3.0 g/kg. All the fungicides under study controlled the seed-borne fungi and increased the germination of sunflower seed to various levels. Tecto and Benlate in both cultivars gave better performance in reducing the fungal population and increasing seed germination. Topsin and Derosal also reduced the fungal population at higher dosage but there was no considerable improvement in germination. The use of fungicides at 2.5 g/kg provided almost complete elimination of fungi and 8-10 percent increase in seed germination as compared to the use of fungicides at 2 g/kg.

Abstract

Background
Sexually transmitted infections continue to be a major health concern in sub-Saharan Africa where antimicrobial drugs are becoming ineffective due to increasing resistance. Many healthcare seekers in lower socio-economic settings depend on invasive alien plants administered by traditional health practitioners to treat sexually transmitted infections.

Methods
Roots of selected plants were analysed for phytoconstituents using standard methods. Both the disc diffusion model and microdilution technique were used to determine the inhibition zone and minimum inhibitory concentration (MIC) of plant extracts against six clinical fungal strains and standard strain of Neisseria gonorrhoea. One-way ANOVA was used to find significant differences.

Results
Different phytoconstituents such as alkaloids, steroids, cardiac glycosides, terpenes, flavonoids, tannins and saponins were qualitatively detected, depending on plant species. Acetone extracted the highest number of phytoconstituents in Senna didymobotrya, while methanol revealed most from Ricinus communis. Senna didymobotrya showed significant inhibition against Candida glabrata, C. krusei, C. parapsilosis and C. tropicalis. Dichloromethane extract of Catharanthus roseus and methanol extract of S. didymobotrya demonstrated excellent MIC values of 0.03 and 0.08 mg/mL, respectively, against C. glabrata. Catharanthus roseus, Opuntia ficus-indica and Ricinus communis demonstrated moderate to good antigonococcal activity, with all exhibiting more than 63% inhibition. Catharanthus roseus had the best antigonococcal activity with a moderate MIC value of 0.63 mg/mL.

Conclusion
Some of the plant extracts demonstrated potency towards clinically isolated fungal strains and against N. gonorrhoea, which validate the notion that some of the species need further pharmacological studies for isolation and characterisation of active compounds.
An energy residual-based approach to gradient effects within the mechanics of generalized continua
Authors: Polizzotto Castrenze , Pisano Aurora A. 
Published: April 2020

AbstractGeneralized continua exhibiting gradient effects are addressed through a method grounded on the energy residual (ER)-based gradient theory by the first author and coworkers. A main tool of this theory is the Clausius-Duhem inequality cast in a form differing from the classical one only by a nonstandard extra term, the (nonlocality) ER, required to satisfy the insulation condition (its global value has to vanish or to take a known value). The ER carries in the nonlocality features of the mechanical problem through a strain-like rate field, being the specific nonlocality source, and a concomitant higher-order long-range stress (or microstress) field. The thermodynamic restrictions on the constitutive equations are determined by the latter inequality with no need for microstress equilibrium equations, whereas the principle of virtual power (PVP) is left in a standard format. The derived state equations include a set of partial differential equations involving the nonlocality-source strain-like quantity and the related long-range stress, as well as the associated higher-order boundary conditions determined by the insulation condition. Second-grade materials within gradient elasticity, gradient plasticity and crystal plasticity, as well as materials with microstructure (micromorphic and Cosserat materials) are considered to derive the pertinent constitutive equations. The proposed ER-based approach to gradient effects is shown to constitute a more straightforward and “economic” way to formulate the relevant constitutive equations than the PVP-based one.

Published: April 2020

AbstractThe purpose of this short communication is to report on some micro/nanoscale aspects of the mechanical behavior of dental porcelain. Specimens were characterized by micro-Raman spectroscopy and scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS). Massive nanoindentation experiments on the surface of the specimens were performed, and typical load-displacement or load-depth (P-h) curves were obtained, which in turn were used to determine the Young modulus (E) and nanoindentation hardness (n-H), based on the Oliver-Pharr method [1]. Statistical analyses were carried out to determine the Spearman’s rank correlation coefficient (Spearman’s ρ), along with non-parametric linear regression analysis by employing Kolmogorov-Smirnov and Two-Step Cluster tests. Densification due to grain boundary diffusion and open-pore elimination was revealed by SEM. EDS analysis indicated a leucite-dispersed silicate glass matrix, as well as its contamination by traces of other minerals. Raman spectroscopy supported the EDS assignments. The P-h curves suggested that inelastic deformation and material flow increases at larger depths. Spearman’s ρ value showed strong dependence of E and n-H on h, indicating the occurrence of a size effect. The logarithmic data of E and n-H as functions of h were fitted by using linear regression analysis. The data did not obey a normal distribution (as the Kolmogorov-Smirnov test showed) due to the chemical heterogeneity involved. The Two-Step Cluster analysis indicated clustering in four groups associated with the chemical heterogeneity of the surface. Similar works using nanoindentation to determine the mechanical properties of dental materials can be found, for example, in [2, 3]. Corresponding methods for extracting the values of E and n-H from P-h experimental curves can be found, for example, in [4–6].
Analysis of damped vibrations of thin bodies embedded into a fractional derivative viscoelastic medium
Authors: Rossikhin Yury A. , Shitikova Marina V. 
Published: April 2020

AbstractDamped vibrations of elastic thin bodies, such as plates and circular cylindrical shells, embedded into a viscoelastic medium, the rheological features of which are described by fractional derivatives, are considered in the present article. Besides the forces of viscous friction, a thin body is subjected to the action of external forces dependent on the coordinates of the middle surface and time. The boundary conditions are proposed in such a way that the governing equations allow the Navier-type solution. The Laplace integral transform method and the method of expansion of all functions entering into the set of governing equations in terms of the eigenfunctions of the given problem are used as the methods of solution. It is shown that as a result of such a procedure, the systems of equations in the generalized coordinates could be reduced to infinite sets of uncoupled equations, each of which describes damped vibrations of a mechanical oscillator based on the fractional derivative Kelvin-Voigt model.
Temporal scaling in fatigue life of materials and incorporation of temporal events in Paris’s law
Authors: Frantziskonis George N. 
Published: April 2020

AbstractTemporal scaling in mechanical strength of materials is vital for long-term effects such as fatigue. The fatigue crack length α is related to the change in the stress intensity factor ΔK by the omnipresent Paris’s law, which works well for cyclic fatigue of specific frequency and amplitude. The paper considers time scaling in fatigue and through it incorporates the effects of temporal events such as unexpected or accidental loads, impact loads, and rare events such as earthquake loads. This is achieved by theoretically incorporating the effects of delta-function type loads into fatigue. Since the time-scale decomposition of such a load contains information at all scales, the theoretical framework is easily extended to include general types of loads.
Complexity theory, time series analysis and Tsallis q-entropy principle part one: theoretical aspects
Authors: Pavlos George P. 
Published: April 2020

AbstractIn this study, we present the highlights of complexity theory (Part I) and significant experimental verifications (Part II) and we try to give a synoptic description of complexity theory both at the microscopic and at the macroscopic level of the physical reality. Also, we propose that the self-organization observed macroscopically is a phenomenon that reveals the strong unifying character of the complex dynamics which includes thermodynamical and dynamical characteristics in all levels of the physical reality. From this point of view, macroscopical deterministic and stochastic processes are closely related to the microscopical chaos and self-organization. The scientific work of scientists such as Wilson, Nicolis, Prigogine, Hooft, Nottale, El Naschie, Castro, Tsallis, Chang and others is used for the development of a unified physical comprehension of complex dynamics from the microscopic to the macroscopic level. Finally, we provide a comprehensive description of the novel concepts included in the complexity theory from microscopic to macroscopic level. Some of the modern concepts that can be used for a unified description of complex systems and for the understanding of modern complexity theory, as it is manifested at the macroscopic and the microscopic level, are the fractal geometry and fractal space-time, scale invariance and scale relativity, phase transition and self-organization, path integral amplitudes, renormalization group theory, stochastic and chaotic quantization and E-infinite theory, etc.

Published: April 2020

Abstract
The objective of this work lies in the three-dimensional study of the thermo mechanical behavior of a blade of a centrifugal compressor. Numerical modeling is performed on the computational code "ABAQUS" based on the finite element method. The aim is to study the impact of the change of types of blades, which are defined as a function of wheel output angle β
2, on the stress fields and displacements coupled with the variation of the temperature.
This coupling defines in a realistic way the thermo mechanical behavior of the blade where one can note the important concentrations of stresses and displacements in the different zones of its complex form as well as the effects at the edges. It will then be possible to prevent damage and cracks in the blades of the centrifugal compressor leading to its failure which can be caused by the thermal or mechanical fatigue of the material with which the wheel is manufactured.
Propagation of longitudinal waves in non-homogeneous four-parameter viscoelastic rods
Authors: Sethi Munish , Gupta Kishan Chand 
Published: April 2020

AbstractThe purpose of this paper was to study the propagation of longitudinal waves in non-homogeneous four-parameter viscoelastic rods of arbitrary thickness. The rods were initially supposed to be unstressed and at rest. Apart from a sudden rising traction uniformly applied over the boundary of the opening and parallel to the faces of the plates, which is steadily maintained thereafter, the rods are otherwise free from loading. Methods for treating reflection at the free end of the finite rod and reflection and transmission at an interface between two media in the semi-infinite bi-viscoelastic rod are also presented. Asymptotic techniques are used throughout, and formal asymptotic wave-front expansions of the solution functions are obtained.

Published: April 2020

Abstract
This study explores entrepreneurship research in Vietnam, a lower-middle-income country in Southeast Asia that has witnessed rapid economic growth since the 1990s but has nonetheless been absent in the relevant Western-centric literature. Using an exclusively developed software, the study presents a structured dataset on entrepreneurship research in Vietnam from 2008 to 2018, highlighting: low research output, low creativity level, inattention to entrepreneurship theories, and instead, a focus on practical business matters. The scholarship remains limited due to the detachment between the academic and entrepreneur communities. More important are the findings that Vietnamese research on entrepreneurship, still in its infancy, diverges significantly from those in developed and emerging economies in terms of their content and methods. These studies are contextualized to a large extent to reflect the concerns of a developing economy still burdened by the high financial and nonfinancial costs.
