Study on Rock-Breaking Depth and Damage Area under Particle Jet Impact

Particle jet impact drilling technology is an efficient method which mainly uses high-velocity particles to break rock. As the important criterion for evaluating rock-breaking effect, rock-breaking depth and damage area were studied in this paper. Firstly, a particle jet impact rock-breaking test device was developed, and laboratory experiments have been carried out. Then, based on the spherical cavity expansion theory, the mathematical model of rock-breaking depth and damage area under particle jet impact was established. Afterward, the effect of water-jet impact velocity, impact angle, and particle diameter on rock-breaking depth and damage area was analyzed by comparing experimental results and mathematical calculation. The results show that rock-breaking depth and damage area would increase with increase of water-jet impact velocity and decrease slightly with increase of particle diameter. And the combination of 8° and 20° is recommended for nozzle layout. The experimental results and mathematical calculation are basically consistent, which could verify the correctness of the mathematical model. The study has significance for development and application of particle jet impact rock-breaking technology and perfection of theoretical research.
On the External Characters of the Blackfish or Pilot Whales (Genus Globicephala)

The coloration and morphometry of the north Atlantic pilot whale Globicephala melaena melaena are described and comparisons made with the subspecies G. m. edwardi , occurring in the southern oceans, the tropical Atlantic G. macrorhyncha and the north Pacific G. scammoni . The north Atlantic pilot whale may show small differences in color pattern from the southern subspecies but no differences have been detected in morphometry. The other two species have dark ventral markings of approximately the same form as G. melaena . The flipper of G. melaena grows more rapidly in length than the body throughout all but earliest postnatal life, while the flipper of G. macrorhyncha is isometric. The latter species thus has a shorter flipper at all except young ages. G. scammoni appears to be intermediate in this feature. G. melaena shows positive allometry of the flipper and dorsal fin in foetal and most of postnatal life but negative allometry between birth and weaning. The functional significance of this feature, found also in the fin whale, is not yet clear.
Evolution of the Design of CH 4

In this review, the evolution of paradigm shifts in CH4 adsorbent design are discussed. The criteria used as characteristic of paradigms are first reports, systematic findings, and reports of record CH4 storage or deliverable capacity. Various paradigms were used such as the systematic design of micropore affinity and pore size, functionalization, structure optimization, high throughput in silico screening, advanced material property design which includes flexibility, intrinsic heat management, mesoporosity and ultraporosity, and process condition optimization. Here, the literature is reviewed to elucidate how the approach to CH4 adsorbent design has progressed and provide strategies that could be implemented in the future.
Effects of winter mowing on vegetation succession

To assess whether winter mowing in wetlands fulfils the aim of preventing succession towards drier communities, 34 permanent quadrats (15 m2) were surveyed annually from 1984-1985 to 2000 within large mown and unmown (control) areas (several ha) in a calcareous lake shore fen (W Switzerland). Three trends were noticed: decrease of aquatic species, spread of Gladioln mariscus and establishment of woody species (especiallyAfints glutinosa and Fran gula abuts). None of these trends was prevented by mowing, but mowing did prevent the accumulation of C. mariscus litter and kept woody saplings small. Succession was generally slow and often occurred in the form of sudden, discrete changes. Plant species richness increased with mowing and remained constant without mowing. Soil disturbance by the mowing machine contributed more to the effects of management on species composition than the periodic removal of biomass. It is concluded that mowing every three years in winter is insufficient to preserve semi-aquatic communities against succession but sufficient to maintain the plant species richness of a low productive, regularly flooded fen.
Prevalence of Celiac Disease in Children and Adolescents With Inflammatory Bowel Disease

Introduction The association between inflammatory bowel disease (IBD) - particularly its two main subtypes, ulcerative colitis (UC) and Crohn’s disease (CD) - and celiac disease (CeD) has been attributed to an overlap in the mechanism of immune dysregulation that characterizes these conditions. Owing to the paucity of studies that have explored this condition in pediatric patients, we examined the prevalence of CeD in children with IBD. Materials and methods This is a cross-sectional study of children aged two to 18 years with IBD that were diagnosed between 2016 and 2018. Clinical, demographic, laboratory, and endoscopic data were analysed. Serology for CeD measured the immunoglobulin A tissue transglutaminase (IgA-tTG) antibodies, and the diagnosis was confirmed histologically through small bowel biopsies. Results The study included 101 patients with IBD (83.2% with UC and 16.8% with CD). The mean age was 8.7±4.0 years. Males constituted 59.4% of the cohort, and only 3% had perianal disease. Ileocolonic involvement was reported in 64.7% and non-stricturing and non-penetrating behaviour in 76.7% of CD patients. Pancolitis constituted 45.2% of UC patients. Ten patients (9.9%) had positive serology based on IgA-tTG antibodies, three (approximately 3%) had CeD based on biopsy findings, two patients (2%) had CD, and one patient (1%) had UC. Patients with confirmed CeD had a significantly higher frequency of symptoms of gaseous sensation and bloating (P=0.003) and abdominal distension (P=0.04). Conclusions The prevalence of CeD in Egyptian children with IBD is higher than previously reported in a number of similar studies. Abdominal bloating and gaseous sensation were identified as associated symptoms.
Advances on Relation between Seed Vigor and Proteins

Seed vigor is currently the highlight of seed research. Great progress in the mechanism of seed vigor has been made in recent year. In this article, we reviewed relation between seed vigor and proteins ——storage proteins, stress shock proteins such as heat shock proteins and other special proteins such as ubiquitin. The homology of stress shock proteins in relative with seed vigor was discussed too.
Mathematical Modeling of COVID-19 Transmission with Mass Testing and Contact Tracing

Corona virus disease or COVID-19 is an infectious disease whose etiological agent has been identified as a novel corona virus known as Severe Acute Respiratory Syndrome Corona virus 2 (SARS CoV 2). Symptoms of the disease include fever, fatigue, loss of smell and taste, dry cough and breathing difficulties in severe cases. The disease is mainly transmitted through discharge from the nose or mouth when an infectious person coughs or sneezes. In this paper, we used a 5-compartmental model incorporating isolation of positive cases to investigate the effect of mass testing and contact tracing on the transmission of COVID-19. The stability analysis of the model showed that the disease-free equilibrium was asymptotically stable when the basic reproduction number is less than unity. Further we performed the sensitivity analysis of the model. The purpose of the sensitivity analysis was to compare the impact of the mass testing to that of contact tracing with the aim of advising the disease control practitioners on the best strategy to stop community transmission in time of limited resources. The results of this analysis showed that mass testing with case isolation had greater impact on community transmission as compared to contact tracing. These results were validated by the use of the numerical simulation of the model. As the number of cases continue to surge and the health facilities get overwhelmed therefore, the health control practitioners need to adopt a control strategy that has the greatest impact on community transmission. The results obtained in this manuscript showed that mass testing followed by case isolation reduced the value of the basic reproduction number much more than contact tracing and is therefore a better strategy in combating community transmission of the disease.

Estimating Poisson pseudo- maximum-likelihood rather than log-linear model of a log- transformed dependent variable

Purpose – The purpose of this study is to account for a recent non-mainstream econometric approach using microdata and how it can inform research in business administration. More specifically, the paper draws from the applied microeconometric literature stances in favor of fitting Poisson regression with robust standard errors rather than the OLS linear regression of a log-transformed dependent variable. In addition, the authors point to the appropriate Stata coding and take into account the possibility of failing to check for the existence of the estimates – convergency issues – as well as being sensitive to numerical problems. Design/methodology/approach – The author details the main issues with the log-linear model, drawing from the applied econometric literature in favor of estimating multiplicative models for non-count data. Then, he provides the Stata commands and illustrates the differences in the coefficient and standard errors between both OLS and Poisson models using the health expenditure dataset from the RAND Health Insurance Experiment (RHIE). Findings – The results indicate that the use of Poisson pseudo maximum likelihood estimators yield better results that the log-linear model, as well as other alternative models, such as Tobit and two-part models. Originality/value – The originality of this study lies in demonstrating an alternative microeconometric technique to deal with positive skewness of dependent variables.
DIABETES AND PERIODONTAL DISEASES : THE BIDIRECTIONAL ASSOCIATION AND ITS IMPLICATIONS

DIABETES MELLITUS (DM) and periodontitis are common, complex, chronic diseases with an established bidirectional relationship. Poorly controlled DM is associated with an increased prevalence and severity of periodontitis, being acknowledged as a true risk factor for periodontitis onset and progression. On the other hand, there is growing evidence that chronic infectious diseases, such as periodontitis, could increase the risk for DM development and compromise glycaemic control in people with DM. In addition, non-surgical periodontal treatment can improve glycaemic control in patients with DM. Therefore, this bidirectional association may have relevant implications for health professionals, for DM and periodontitis patients, as well as for the general population. Due to these implications, dental professionals may play an important role in the management of DM patients, not only by rendering periodontal care in people with DM, but also helping identify patients with undiagnosed DM or at high risk of developing it, by the use of appropriate screening tools. The aim of this narrative review was (1) to address the mechanistic links that have been proposed as basis of the periodontitisDM relationship; (2) to report the epidemiological evidence from cross-sectional and longitudinal studies; and (3) to describe the impact of periodontal care on DM control. Recommendations for medical and dental professionals, as well as recommendations for patients/public are proposed.

Learned rotationally symmetric diffractive achromat for full-spectrum computational imaging

Diffractive achromats (DAs) promise ultra-thin and light-weight form factors for full-color computational imaging systems. However, designing DAs with the optimal optical transfer function (OTF) distribution suitable for image reconstruction algorithms has been a difficult challenge. Emerging end-to-end optimization paradigms of diffractive optics and processing algorithms have achieved impressive results, but these approaches require immense computational resources and solve non-convex inverse problems with millions of parameters. Here, we propose a learned rotational symmetric DA design using a concentric ring decomposition that reduces the computational complexity and memory requirements by one order of magnitude compared with conventional end-to-end optimization procedures, which simplifies the optimization significantly. With this approach, we realize the joint learning of a DA with an aperture size of 8 mm and an image recovery neural network, i.e., Res-Unet, in an end-to-end manner across the full visible spectrum (429–699 nm). The peak signal-to-noise ratio of the recovered images of our learned DA is 1.3 dB higher than that of DAs designed by conventional sequential approaches. This is because the learned DA exhibits higher amplitudes of the OTF at high frequencies over the full spectrum. We fabricate the learned DA using imprinting lithography. Experiments show that it resolves both fine details and color fidelity of diverse real-world scenes under natural illumination. The proposed design paradigm paves the way for incorporating DAs for thinner, lighter, and more compact full-spectrum imaging systems.
Shrinking Capitalism

A defining feature of capitalism is that work using privately owned capital goods is performed under the control of an owner or manager in return for wages, producing goods to be sold for profit. Does this describe the work done in the high-income economies of today— much of it knowledge and care based, and more than half of it in the public sector or unpaid? And where the description does fit, is this a good way of organizing production? We think the answer in both cases is “not really. ” The double entendre in our title is thus intentional: because the sectors of the economy in which this system of production works tolerably well are already small and shrinking, it is imperative on not only moral but also economic grounds to develop a paradigm for policies and institutional design that will shrink capitalism while sustaining innovation and economic dynamism. Rethinking current policy and institutional options is essential to preserving and enhancing freedom in a world in which the destruction of communities and social alienation of many citizens are fueling authoritarian movements. Tools for doing this have been provided by the incomplete contracts and behavioral economics revolutions, which overthrew the vision of the firm and social interactions in the conventional Marshall–Walras tradition. Here we deploy these recent developments in economics to outline a framework for a well-functioning economy under contemporary conditions that is consonant with values summarized by a broad concept of freedom and that goes considerably beyond a fair distribution of rising material living standards and is better able to support a more just, democratic, and sustainable society.
Mexican heritage Spanish speakers’ vowel production in cognate and non-cognate words

Previous research describes the Spanish vowel system as a stable five-vowel system (Delattre, 1969; Hualde, 2005; Navarro Tomás, 1918). Recent findings have challenged this claim (Delforge, 2008; Willis, 2005) with reduction of unstressed vowels reported in monolingual Mexican Spanish (Butragueño, 2014). Variation of the vowel system has also been reported in studies of heritage Spanish (Boomershine, 2012; Ronquest, 2012). The current study examines Mexican heritage Spanish (i.e. early bilingual) vowel production in cognate and non-cognate words in comparison to a late bilingual group. Both early bilinguals and late bilinguals show a constricted back vowel space and a wider front vowel space in cognate and non-cognate words. Vowels in cognate words showed significantly more centralization than those in non-cognate words.
Response of vetch varieties to Sitona lineatus L. in organic farming

Abstract Sitona lineatus L. (Coleoptera: Curculionidae) is an important pest of field vetch in Bulgaria. The response of vetch varieties to S. lineatus was determined on the basis of seedling vigour, plant phenological development and chemical analysis of the feed. The susceptibility to attack by S. lineatus of the vetch, Vicia sativa L. , varieties, Liya, Loryna, Villena, Moldavskaya 82 and Vicia villosa Roth varieties, Violeta and Viola, was tested. Vetch varieties with high vitality and rapidly growing seedlings such as Liya and Loryna were considerably less preferred by S. lineatus. They were distinguished with low damage degree and leaf damage intensity. Weather conditions during the years affected population density and food activity of Sitona weevils as the harm was particularly great in the dry spring in 2013, when the plants had suppressed growth and did not develop normally. The least preferred variety with a low S. lineatus density was Liya followed by Loryna, which were characterized with the shortest vegetative season (67 days), high seedling vigour and high fibre content. The most preferred varieties with the highest density of weevils were winter varieties Violeta and Viola, which had high crude protein content.
Influence of Quality of Work-Life on Organizational Citizenship Behaviour: A Case Study of Selected Ministries in State Secretariat, Abere, Osogbo, Osun State, Nigeria

The study investigated the influence of quality of work-life on organizational citizenship behaviour (OCB) among civil-servants in selected ministries in State Secretariat, Osogbo, Osun State. A total of 200 civil-servants took part in the study as respondents. Questionnaire was used for data collection in the study. Collected data were analyzed using both Descriptive and Inferential statistics. The findings revealed that quality of work-life have significant influence on organizational citizenship behavior among civil servants, Quality of work-life significantly influenced courtesy among civil servants, Quality of work-life significantly influenced civic virtue among civil servants, Quality of work life significantly influenced conscientiousness among civil servants, Quality of work life significantly influenced sportsmanship among civil servants. Gowever, Quality of work life did not significantly influence altruism among civil. It is therefore concluded that quality of work-life significantly influenced organizational citizenship behavior among civil-servants. It was recommended that ministries should give priority to quality of work-life which willenhance altruism, conscientiousness, civic virtue, sportsmanship and courtesy that will encourage the employees to perform better and show willingness to achieve the organizational goals.
Effect of Cu on Pigmentation and Survival of Pseudomonas stutzeri

Pseudomonas stutzeri is an aerobic, green fluorescent bacterium which secretes green pigment in aerobic condition. In this article the release of bluish-green, luminous, water -soluble stain by P. stutzeri was discussed in presence of Cu metal in relation with the survival of P.stutzeri in nutrient medium. The activity of Pseudomonas stutzeri was monitored in provisions of colors of pigment with varying concentrations of Cu metal in petri dish. Results showed a variation in colors of pigment with different concentration of Cu metal. It was light green with water while colourless at high concentration of metal and blue with the moderate concentration of Cu. It was observed that high concentration of Cu results in the death of all microorganisms may be due to the reaction of Cu with oxygen or Cu responsible to decrease the BOD which ultimately affects the biosynthesis of pigment. No color of Cu with any life of Pseudomonas stutzeri at high dose also indicates that the Cu adsorbed on dead mass of bacterial strain. Less microbial life at low and moderate concentration of Cu with blue color reflects that Cu may be bonded with the pigment. It was concluded that Cu2+ was bactericidal to the phytopathogenic bacterium Pseudomonas stutzeri in the micromolar range which inhibits the biosynthesis of pigment at high concentration and bacteria experience death. It was suggested that pigmentation property of Pseudomonas stutzeri can be used as a monitoring tool of contaminated soil by heavy metals.
EFFECT OF ACC DEAMINASE BACTERIA ON TOMATO PLANTS CONTAINING AZO DYE WASTEWATER

The effect of plant growth promoting rhizobacteria (PGPR) on seedling germination, plant growth and biomass yield of tomato plant in presence of dye wastewater irrigation was evaluated in 2 experiments (lab scale and green house). Previously isolated strain Pseudomonas fluorescens (Q14) with ACC deaminase activity was used to check its effect to remedify dye contaminated water impact on plants. The maximum biomass production was obtained on application of 600 mg/L dye with selected PGPR as compared to control water. The dye concentration beyond 600 mg/L showed significantly repressed growth of plants. In plant biomass analysis root and shoot biomass were measured while in plant growth root, shoot length in both experiments was compared. It was also observed that the inoculation with plant growth promoting bacteria carrying ACC deaminase activity promote root and shoot growth as compared to un-inoculated plants at different Reactive Black B concentrations. Maximum shoot (46 cm) and root length (35cm) was observed at 600 mg/L of Reactive Black B with inoculation, which clearly implies the importance of industrial wastewater for crop and vegetable grown under water stress conditions. These findings suggest that PGPR with ACC deaminase activity could be implied for increasing biomass production of wheat and maize irrigated with dye containing wastewater released from textile industries.
