Combined Effect of Ignition Energy and Initial Turbulence on the Explosion Behavior of Lean Gas/Dust-Air Mixtures †

Explosions of hybrid mixtures of methane and nicotinic acid are investigated near the lower-flammability-limit conditions. The effect on the maximum pressure and deflagration index of the ignition energy and, then, of the ignition source in combination with the turbulence is analyzed. In correspondence of limit conditions for pure methane and pure nicotinic acid, the variation of both the ignition energy and the turbulence was found to affect the behavior of the explosion. It was observed that the deflagration index is determined to be independent from the ignition energy, even though the dependence on the turbulence still remains.

Electric vehicles business models: an integrative framework for adoption of electric mobility

The study presents four business models currently being operational in different parts of the world in order to support the commercialisation drive of electric vehicles (EVs). With the help of extant literature, the author develops systematic and multidimensional frameworks on value creation and customers' adoptions barriers related to EVs. These multidimensional frameworks are then used to analyse the selected business models for their strengths and weaknesses. Findings of the study underscore differences in the business models adopted by the selected players with Tesla and e2o emphasising on product innovation while the other two, i.e., Carma and Wanxiang, focusing on the service dimension. The study recommends that adoption of a holistic approach combining product and service orientation in business models is necessary for wide-spread adoption of EVs. Besides, the role of forging partnerships across the value-chain partners and having policy support are also highlighted as key success factors for EVs.

Mid-West Summer Weather and the Way of Least Friction

A typical summer weather event in the mid-west starts with a cool dry wind moving south near the Rocky Mountains and an equal mass of warm moist air moving north to the east of it in a side by side arrangement. Arguments supporting this proposition include observations, theory and one assumption. Observations are an awareness of the predominately north/south wind directions at one point in northwest Iowa for more than 30 consecutive summers as well as knowledge of the eastward flourishing vegetation distribution throughout the mid-west starting at the Rockies. The theory is the expectation that in geophysical flows the configuration most likely to persist and be observed has the least amount of friction among all possibilities. One assumption is that only a single southward cold wind takes place at one time to initiate the weather “cycle”.
Relationship between physical and biochemical parameters in apple softening

Postharvest softening of apple is one of the most important problems resulting in quality losses for growers and distributors all over the world. Factors affecting apple softening must be well known to provide a good quality apple to the market all year round. Therefore, our research focuses on the physical and biochemical parameters causing and related to apple softening. Rapid postharvest softening of apple is the result of an undesired, fast ripening process. The two main reasons for apple softening are water loss due to transpiration and cell wall breakdown due to enzymatic activities. The former has a considerable influence on the turgidity of the cells (thus on the stiffness of apple), while the latter affects mainly the firmness of the apple due to reducing the mechanical strength of cell walls. The apple cultivar 'Delbard Estival' was studied during 2 months storage at 18°C, 80-90% relative humidity (shelf life conditions). The acoustic stiffness coefficient, water potential, Brix value, penetrometer firmness, bruise susceptibility and activity of polygalacturonase were investigated. Both the acoustic stiffness coefficient and penetrometer firmness decreased considerably during storage following the characteristic three phase softening curve. Water potential and bruise susceptibility also decreased during storage due to the decrease in turgidity of the apple tissue. The activity of polygalacturonase showed an exponential increase in the first 30 days. The acoustic stiffness coefficient during storage was largely determined by the initial stiffness. The acoustic stiffness coefficient related to penetrometer firmness and water potential. There were also correlations found between water potential and soluble solids content. Bruise susceptibility was affected by both stiffness and the weight of the fruit.
Efficacy of Savory Essential Oil Utilization in Conventional and Encapsulated Forms on Performance of Broiler Chickens

This survey aimed to evaluate the effects of dietary supplementation of different forms of savory essential oil (SEO) on growth performance, intestinal morphology and microbial population in broiler chickens. A total of 360 one-day-old male broilers were randomly allocated to 6 dietary treatment groups with 5 replicates per treatment and 12 birds per pen. The experiment consisted of a 2×3 factorial arrangement including two different forms [encapsulated SEO (ESEO) and nonencapsulated SEO (NSEO)] in three levels (0, 150, and 300 mg/kg diet) of SEO. Growth performance, jejunal morphology and intestine microbial population were examined. Our results revealed that feed intake was not influenced by the dietary treatments in different experimental periods. As well as, the experimental diets did not influence body weight gain (BWG) and feed conversion ratio (FCR) during the starter period. However, at the grower, finisher, and also whole rearing periods, broilers which received 150 mg/kg SEO had significantly higher BWG and lower FCR compared to the birds fed the control diet. The final body weight (FBW) was also higher in chickens fed with diet supplemented with 150 mg/kg SEO in comparison to the others. The results also revealed that 150 mg/ kg SEO, significantly increased the concentration of Lactobacillus and decreased the intensity of coliforms in the ileal digesta in comparison to the control diet. Furthermore, villus height was significantly lower in birds fed the control diet than in the birds that consumed different levels of SEO. Eventually, the findings of this experiment revealed that dietary supplementation of SEO, especially at 150 mg/kg level, was effective in raising the populations of beneficial microorganisms in the gastrointestinal tract as well as improving intestinal morphology and growth performance of broilers.
Comparison of Tp-e interval, QTc interval and Tp-e/QTc ratios between non-diabetic and prediabetic population

Aim: Increased blood glucose concentration and cardiac autonomic nerve dysfunction are associated with an increased risk of malignant ventricular arrhythmia. Tp-e interval, Tp-e/QT, and Tp-e/QTc are novel parameters used to assess ventricular arrhythmogenicity. This study aimed to compare these parameters with the healthy control group in prediabetics. Materials and Methods: The ECGs of 58 prediabetic patients (29 male, 59.74 ±13.25 years) were examined and matched with the ECGs of 59 healthy controls (28 male, 61.75 ± 12.66 years) that were matched with gender, age and body mass index. From the 12-lead ECG Tp-e and QT intervals were measured and by Bazett's formula QTc was calculated. Tp-e/QT and Tp-e/QTc proportions were also determined. Results: In prediabetic patients, the mean Tp-e interval was significantly longer than the control group (79.07 ± 8.17 vs 72.03 ± 9.77 ms, respectively; p
Enhancing Attainment of Graduate Attributes through Data Mining

Graduate Attributes (GAs) in outcome-based education (OBE) are a major concern of the stakeholders, especially students, which are to be assessed during their academics. ​ National Board of Accreditation, India has suggested graduate attributes which in turn help students in the attainment of educational objectives. The graduate attributes are salient and important for all the graduating students. Graduate attributes are acquired through curricular, co-curricular and extra-curricular activities. Analyzing a student’s performance during their academics is crucial for increasing the chances of employability. Currently, no system measures students' performance based on graduate attributes. This system supports collection, management, analysis and visualization of graduate attributes. We propose a model that produces graduate attribute scores based on the credentials entered by the student and provides recommendations for activities required to attain all graduate attributes as output. This model also provides improved visualization of reports in graph and tabular form. This paper is an attempt to help in enhancing the standards of the higher education system by evaluating students’ data through the foremost attributes that reflect student performance.
Creating a more immersive and "vR-like-360-degree video experience- development of an immersive and interactive alcohol resistance training tool

The presented design case gives an example of how to create more engaging 360-degree video applications. In contrast to VR, users of 360-video are often passive observers; they cannot move around in the virtual environment nor affect it. This limits the user's chance of feeling immersed and present in the environment, resulting in less engaging experiences and poorer conditions for experience-based learning. This article examines immersion in 360-video through the design case VR FestLab (ed. In English PartyLab), which is a party simulation for alcohol prevention, consisting of 125 360-degree movie sequences. The application is used in a virtual reality headset, where users create their own uniqueexperience through a choose your own adventure experience. The application is an example of a new approach towardsmore engaging 360-degree video content. In the light of this, we suggest six elements that should be considered, whendesigning an engaging, motivating and immersive experience with 360-degree video. The six elements are 1) user influence, 2) noticed user existence, 3) 3D environment, 4) spatial sound, 5)" movement" in scene and 6) technical aspects.Further tests are needed to fully determine the extent to which these six factors enhance immersion and presence.

This investigation dealt with the investigation of the effects of GLP-1 analogue, liraglutide on the expression of mouse pre-osteoblast MC3T3-E1, MC3T3-E1 cells were cultured, passaged and frozen. Cell lines were cultured under different conditions and were separated into control group exposed to saline and groups 2, 3 and 4, which were exposed to 10-9 M, 10-8 M and 10-7 M liraglutide, respectively. Group 2 cells after 2 d of intervention were subjected to CCK-8 assay for cell proliferation, flow cytometry for cell apoptosis and Western blot for protein expression. The expression of osteoblast differentiation marker genes, GLP-1R, Runx2, OCN and ALP were detected using real-time fluorescence quantitative PCR 3, 6, 12 and 20 days after intervention. The results showed that liraglutide promoted proliferation of osteoblasts and the reduced early apoptotic rate of osteoblasts, which indicated that liraglutide could promote the proliferation and differentiation of mouse osteoblasts MC3T3-E1 and inhibited the apoptosis of cells.
RSA ALGORITHM ELEMENTS IN TERNARY AFFINE TRANSFORMATIONS IN ENCRYPTION-DECRYPTION OF IMAGES

Regarding image encryption, a crucial task is to implement the application of such an RSA algorithm which will provide an opportunity: – not to decay the cryptographic stability of the RSA algorithm; – to ensure complete noisiness of an image to prevent the application of methods of visual image processing. An algorithm for encryption-decryption of monochrome images using elements of the RSA algorithm as the most resistant to unauthorized signal decryption in ternary affine transformations is proposed. The developed algorithm is applied to images in which there are strictly delineated contours. Elements of the RSA algorithm are proposed to be used to construct the coefficients of ternary affine transformations. The proposed algorithm has higher cryptographic stability compared to the RSA algorithm. The ways of applying the elements of the RSA algorithm in affine transformations in encryption-decryption of images are described in this article. The results of modeling the affine modified cipher for cryptographic transformations of black and white monochrome images of a given dimension are presented. Modified models and algorithmic procedures of key generation processes, direct and inverse cryptographic transformations, which are reduced to matrix element-by-element operations by module, are developed.
AI Strict Liability Vis-à-Vis AI Monopolization

Some argue that applying a strict liability regime on AI-inflicted damages may allow well-financed big AI companies to monopolize the industry. They hypothesize that a strict liability regime would expose AI companies to significant legal liability. Since small AI companies lack the necessary resources to pay for damages inflicted by their AI technology, a strict liability regime could erect barriers to entry for these small companies. Ultimately, the argument continues, such a regime would give a small group of companies a virtual monopoly on the AI industry. Thus, some conclude that strict liability inherently stifles innovation and should not be applied to emerging technologies, such as AI. This Article maintains that legislators should adopt a strict liability regime, and it rejects the above argument for two reasons. First, there is no substantial connection between a strict liability regime and the AI monopolization that is already underway. Second, insurance policies could mitigate the effects a strict liability regime may have on the capabilities of small AI companies to enter and compete in this important market. Therefore, the ongoing process of monopolization of the AI market should not by itself render strict liability a non-viable regime when AI-inflicted damages occur.

Electrochemical Determination of Nitrite Using a Reduced Graphene Oxide–Multiwalled Carbon Nanotube-Modified Glassy Carbon Electrode

ABSTRACT Graphene oxide nanosheets were encapsulated with multiwalled carbon nanotubes by direct reduction on glassy carbon to obtain a reduced graphene oxide/multiwalled carbon nanotube-modified electrode. The encapsulated multiwalled carbon nanotubes facilitated the reduction of graphene oxide with characterization by atomic force microscopy, scanning electron microscopy, and Raman spectroscopy. The reduced graphene oxide–multiwalled carbon nanotube-modified electrode exhibited high catalytic activity for the oxidation of nitrite. Under the optimized conditions, the modified electrode had a linear dynamic range from 0.2 to 640 µM with a detection limit of 0.07 µM. This device was used to determine nitrite in water samples and satisfactory results were obtained.
lncRNA RBM5‐AS1 promotes cell proliferation and invasion by epigenetically silencing miR‐132/212 in hepatocellular carcinoma cells

Hepatocellular carcinoma (HCC) is regarded as one of the most common malignancies worldwide leading to cancer‐related death. Long noncoding RNAs (lncRNAs) are a critical modulator affecting HCC progression. Whereas, the pathogenesis of lncRNA RBM5‐AS1 in the development of HCC remains unclear. Quantitative RT‐PCR or western blot assays were applied to detect the expression of genes and proteins, respectively. The proliferation and metastasis abilities were assessed using Cell counting kit‐8 (CCK‐8), EdU and transwell assays. RNA immunoprecipitation (RIP) experiment was employed to validate the molecular interactions. RBM5‐AS1 is highly expressed in HCC tissues and cell lines, especially in Hep3B and HepG2 cells. RBM5‐AS1 knockdown dramatically restrains cell proliferation, invasion and migration of HCC cells. Importantly, RBM5‐AS1 acts as an epigenetic regulator to elevate the H3K27me3 level of miR‐132/212 promoter regions via recruiting PRC2 (EZH2, SUZ12, EED), and eventually reducing miR‐132/212 expressions. The recovery experiments demonstrated that downregulation of miR‐132/212 markedly eliminate the antitumor effects mediated by RBM5‐AS1 silencing in HCC cells. The data of this work illustrate that RBM5‐AS1 acts as an epigenetic regulator to promote the HCC progression by repressing miR‐132/212 expressions, which would provide a new insight for understanding the action mechanism of RBM5‐AS1 in HCC development.
