The path towards delamination-free drilling of composite materials

The fiber-reinforced composite materials possess advantage for structural purpose in various industries. Delamination is considered the major concern in manufacturing the parts and assembly. Drilling is frequently applied in production cycle while the anisotropy and nonhomogeneity of composite materials affect the chip deformation and machining behavior during drilling. Traditional and non-traditional drilling processes are feasible for making fine holes for composite materials by carefully selected tool, method and operating conditions. In this article, the path towards the delamination-free drilling of composite material is reviewed. The major scenes are illustrated including the aspects of the analytical approach, the practical use of special drill bits, pilot hole and back-up plate, and the employment of non-traditional machining method. © 2005 Published by Elsevier B.V.

ON BIOLOGICAL HYDROGEN PRODUCTION USING DIFFERENT BIOMASS

Hydrogen is a clean and efficient fuel, considered as a potential and more sustainable energy substitute for fossil fuels. Biological hydrogen production stands out as an eco friendly process carried out under mild operating conditions with renewable resources. In the current work laboratory scale production of hydrogen using phototrophic purple non-sulphur bacteria Rhodobacter sphaeroides, anaerobic dark fermentative bacteria’s Clostridium pasteurinum, Bacillus licheniformis and Enterobacter clocae with different substrates were investigated. The study investigated the potential of biological conversion of different substrates to produce hydrogen by studying various experimental parameters like temperature, pH and optical density (OD) of cells. It was found that the Rhodobacter sphaeroides took relatively longer duration (48 hrs) for hydrogen production. The optimum temperature and pH for maximum production of hydrogen in case of Rhodobacter sphaeroides were found to be 32°C and 7.5 respectively, 32°C and 7 for Clostridium pasteurinum respectively, 30°C and 6.8 respectively for Bacillus licheniformis and Enterobacter clocae. Results of the batch tests showed that Rhodobacter sphaeroides produced maximum amount of hydrogen (35%) as compared to 21% by Clostridium pasteurinum, 16% by Bacillus licheniformis and 8% by Enterobacter clocae. However the quantity of hydrogen production in case of Rhodobacter sphaeroides was relatively lower compared to Clostridium pasteurinum.
Fingerprint based biometric authentication for ATM system

In this modern world, technologies are rapidly transforming. The technology provides simplicity and comfort yet in addition brings a major worry for security. So to increase the security to the present ATM framework, biometric and GSM technology can be used. In this paper, we proposed a system in which banker will collect customer’s fingerprint and mobile number while opening accounts and at that point just client will have the capacity to get to ATM machine. The essential advance of this framework is to check as of now filtered unique mark with enrolled fingerprints. If these fingerprints are matched, then an OTP will send to the customer’s mobile using GSM technology. This system needs fingerprint scanner, card reader and raspberry pi is used to interface all components. Keywords— Biometric, fingerprint, authentication, raspberry pi, card reader,OTP.
THE EFFECT OF GROWTH BIOSTIMULATORS AND HERBICIDE ON THE CONTENT OF SUGARS IN TUBERS OF EDIBLE POTATO ( SOLANUM TUBEROSUM L . )

Currently, new solutions are searched for in crop production that will provide plants with favourable conditions for growth and development, ensuring high consumer quality of harvested products further to being friendly for the environment. One of the most important features negatively affecting the quality of consumer quality of edible potato tubers is the increased content of total sugars and especially reducing sugars. Therefore, the aim of the experiment was to determine the impact of five methods of care using the growth biostimulators and herbicide on the content of total sugars and reducing sugars in tubers of three edible potato varieties. A series of three-year field experiments was carried out in the years 2015-2017 in the region of Eastern Poland (52°02'N; 23°07'E). The experiments were assumed with random sub-blocks method in three repetitions, on light acidic soil. The examined factors were: I factor – three early edible potato varieties (Owacja, Bellarosa, Vineta), II factor – five methods of care using growth biostimulators: GreenOk – Universal Pro and Asahi SL and their combination with Avatar 293 ZC herbicide. As a result of the studies, it was concluded that genetic features of the cultivated varieties, as well as methods of care applied in the experiment did not have a significant impact on the content of total sugars and reducing sugars in tubers of potato. The value of these characteristics substantially depended only on the course of thermal-precipitation conditions in the given years of research. Significantly higher content of total sugars (an average 0.74%) was shown by the tubers harvested in a warm and dry growing season of the year 2015, whilst the highest content of reducing sugars in tubers was recorded in a cool, wet growing season of 2017 (an average of 0.39%).
Channel bed adjustment of a large sand-gravel bed river to an intermitted sediment sink

A large mixed-bed alluvial stream (Vereinigte Mulde near Bitterfeld, Sachsen-Anhalt, Germany) with a riffle-pool bed was investigated for bed form morphodynamics. The study focused on flood-associated processes. It is based on bathymetric monitoring of selected channel reaches and systematic bed material sampling. Evaluation increased the understanding of undulating channel beds, their maintaining processes and channel bed adaptation to a sediment deficit. A sediment sink divides the stream into an undisturbed upstream and a disturbed downstream reach. Channel changes downstream of the sink were for the first time systematically surveyed and analysed. Amplitudes of longitudinal channel profiles proved to be a significant morphometric parameter of the surveyed type of stream. High bed amplitudes indicate pronounced scour of pools and fill of riffles during floods. Maximum aggradation of riffles and degradation of pools lagged behind peak discharges. During these periods the channel bed is mobile. With flows falling under a threshold value, bed amplitudes decrease and bed mobility is restricted to downsloping stretches of the channel bed. These changes are closely related to flood events. Higher values of bed amplitudes were permanently observed at the downstream reach and are interpreted as an indicator for the sediment deficit there. The results of detailed morphometric analysis show that permanent degradation of the disturbed, downstream channel bed affects the downstream pools selectively. Riffles appear to be unaffected. An approach to estimate bed stability based on the comparison of the two reaches is introduced. It corroborates the survey analysis and explains that an apparent general channel incision downstream is pretended by a larger wetted cross section due to a smaller river gradient. The findings give rise to the hypothesis that form roughness is increased by greater bed amplitudes, be it periodically, flood-associated or permanently induced by a sediment deficit.
THE DETERMINANTS OF PURCHASE INTENTION ON COUNTERFEIT SPORTSWEAR

This study looks into the determinants of purchase intention on counterfeit sportswear based on Theory of Reasoned Action. This is a cross-sectional study and purposive sampling was applied. Survey data was collected from 200 respondents aged below 30. Using Partial Least Square Structural Equation Modeling (PLS-SEM), result indicated that attitude influences purchase intention on counterfeit sportswear, where attitude is predetermined by materialism and subjective norms but not integrity. Creating an environment which disfavor the attitude towards counterfeits is important in curbing counterfeits consumption issue.
Coherent turbulence structure generated by wind-induced water waves

It is very important for global environment problems to reveal turbulence characteristics and coherent structure generated by wind-induced water waves. Some previous studies pointed out that the turbulence generation depended on phases of water waves, in which single-point measurements of a laser Doppler anemometer (LDA) were conducted intensively. However, there remain uncertainties about the effects of wave phases on coherent turbulence motion, e.g., ejections & sweeps, and streaky structure. Simultaneous measurements of velocities and free-surface elevation allow us to conduct reasonably the phase analysis of the coherent structure in interfacial shear layer. Particularly, multi-point measurements such as PIV are very powerful to detect the space-time structure of coherent motions. Therefore, in the present study, we developed a specially designed PIV system which can measure the velocity components and surface-elevation fluctuations simultaneously by using two sets of high-speed cameras to reveal the coherent structure in the interfacial shear layer between water and wind.
MATRIX METALLOPROTEINASE-8-A SALIVARY DIAGNOSTIC BIOMARKER RELATED TO SOFT TISSUE DESTRUCTION IN CHRONIC PERIODONTITIS

Periodontitis is a bacteria-induced chronic inflamm ation affecting the tooth-supporting structures. A major challenge in clinical periodont itis is to find a novel diagnostic tool for an objective evaluation of the periodontal status. The aim of this study is to assess the value of salivary Matrix metalloproteinase (MMP)-8, a neu trophil-derived proteolytic enzyme, as an indicator of the severity of periodontal tissues destructions. The study included 11 chronic periodontitis patients and 10 healthy contr ols. Clinical parameters including periodontal index (PI), bleeding on probing index ( BPI), probing depth (PD) and clinical attachment level (CAL) were recorded, and saliva sa mples were collected. MMP-8 salivary levels were measured using an ELISA quantitative co lorimetric assay. The chronic periodontitis patients underwent initial therapy (s caling and root planning) followed by periodontal surgery. The soft tissue wall of the pa thologic periodontal pocket was excised and examined microscopically. Statistical analysis (the independent samples test and Pearson correlation coefficient) was employed to co mpare the clinical parameters with MMP-8 salivary levels. We also compared these data with the histopathological findings. Our results indicated that there was a correlation between the periodontal status evaluated using clinical parameters, MMP-8 salivary levels an d the histopathological changes. Salivary MMP-8 can be taken into consideration as a biomarker of periodontitis and could be used as a valuable indicator of health and patho logic process.
SHADING AND VEGETABLE-BREAD-FISH WASTE COMPOST EFFECTS ON GROWTH AND YIELD OF FIELD GROWN

Medicinal herb production has become more challenging nowadays as it is demanded, as far as possible, to avoid chemical fertilizers and other agrochemicals for higher quality of the produce. The present study was a split plot experiment conducted to examine the effect of shading and application of compost derived from dumped brassica vegetable-dumped or expired bread-fish gill and internal organ (3:2:1) wastes towards growth and yield of Andrographis paniculata grown in open field as alternative to conventional organic fertilizers in current market. Main plots were plots of full sunlight and 50% relative light intensity (RLI) as achieved by commercial 50% shade netting. Within each main plot, sub plots of treatments at 0 g compost + 5 g nitrophoska (NPK) green/plant, 0, 25, 50, 75 and 100 g compost/plant, respectively, were laid out at random. Fertilization was carried out only once throughout the production period of eight weeks. Each sub plot treatment was replicated four times, each with three plants per replicate. Results indicated that plant grown under full sunlight combined with application of 100 g compost/plant, or 3 tonnes compost/hectare at 30,000 plants/hectare, was the best, especially in production of leaves as its main economic plant part for the herbal industries. Such inorganic fertilizer free plants were better than the recommended inorganic 5 g NPK green /plant or at a rate of 150 kg/hectare fertilization in production of this medicinal plant.
Academic engagement with industry: implications for scientific productivity and research agenda composition

We investigate the relation between industry engagement of academic researchers and the production of scientific research. We specifically contribute to the question whether academic engagement affects the nature of the research produced. Based on survey data of German professors from all sciences and engineering, we show that industry funding relates with a stronger orientation of the research agenda towards industry. Concretely, they are more likely to consider industry a main user of their research, to develop their research agenda along potential for knowledge transfer activities, and to indicate that they would have new research topics funded by industry. Our data further shows that this orientation to some extent runs counter to scientific interests. Our findings indicate that the current trend towards more intense industry funding of research might influence the long-term development of scientific knowledge.
Do Immigrants Have Lower Participation Rates in U.S. Financial Markets?

This paper uses data from the National Longitudinal Survey to examine the differences in individual financial market participation among native-born and immigrant Americans. The results indicate that when compared with natives, immigrants are less likely to own financial assets. A decomposition analysis of financial asset ownership reveals that income gap along with differences in educational attainment as well as the wealth and risk tolerance are the biggest contributors to this disparity. Additionally, income, wealth, inheritance, and educational attainment are positive predictors of financial market participation. Age, income, net worth and number of years of stay in the United States are positively associated with increase in financial wealth of immigrants across time.
Key comparison BIPM.RI(I)-K2 of the air-kerma standards of the VSL, Netherlands and the BIPM in low-energy x-rays

A key comparison has been made between the air-kerma standards of the VSL, Netherlands and the BIPM in the low-energy x-ray range. The results for the direct comparison show the standards to be in general agreement for the 10 kV, 30 kV and 25 kV radiation qualities at the level of the expanded uncertainty for the comparison of 6.6 parts in 103. For the 50 kV qualities, differences approaching twice the expanded uncertainty are observed. The results for an indirect comparison made at the same time are not consistent with the direct results, in the worst case (10 kV) differing by 4 parts in 102. The results are analysed and presented in terms of degrees of equivalence, suitable for entry in the BIPM key comparison database. Main text.

Have the Tropical Pacific Ocean-Atmosphere Interactions Behaved as a Driver of Centennial-to Orbital-Scale Climate Changes ?

We review recent studies of the long-term El Niño-Southern Oscillation (ENSO)-like variability and its relationship to global climate changes on centennial to orbital time scales. A synthesis of the published studies and data for the long-term ENSO-like variability demonstrated that an El Niño-like pattern of the Pacific has been linked to global warming and pCO2 increase on millennial to orbital time scales, which suggests that the tropical Pacific plays a major role in global climate changes.
WHAT EXPLAINS IPO UNDERPRICING ACROSS COUNTRIES ? The Influence of Country Characteristics on the IPO Underpricing Anomaly

This paper examines why the average first-day returns on initial public offerings vary across countries. The average first-day returns for countries vary from around -2% to around 76% in this study. I examine 2028 IPOs from 36 countries of different continents over the period 2009-2018. I provide support for the country-risk, the legal environment, and the culture hypothesis. Countries that have more technology firms and higher litigation risk experience more IPO underpricing. These results are robust to time effects and changes in the sample. Sub samples show that internet firms increased the level of underpricing in an earlier period.
Store Choice Behaviour in Food and Grocery Retailing in India-An Empirical Analysis

Shopping for food and grocery products has witnessed a paradigm shift in Indian retail market with the changes in consumer buying behaviour driven by strong income growth, changing lifestyles and favourable demographic patterns. But the very fast changing trends in consumption patterns, food and eating habits of consumers have contributed immensely to the growth and development of 'Western' format typologies such as convenience stores, discount stores, super markets, and hyper markets. The present study is exploratory in nature to identify and examine the determinant attributes influencing consumer behaviour towards super market store format choice decisions in the fast growing food and grocery retailing in India. The population of the study is confined to the retail customers (7.5 crore) ofAndhra Pradesh state and sampling sources are twin cities of Secunderabad and Hyderabad (58 Lakh population). The 'mall intercept' survey method is adopted to study the attitudes and opinions of retail customers through questionnaires. The descriptive statistical tools (like mean, standard deviation and median) and inferential statistical tools like Factor Analysis, Chi-Square, ANOVA, Correlation, and Multiple regressions are used to test the formulated hypotheses and validate the model. The study has found significant association between shopper attributes and store format choice decisions. The findings revealed that merchandise, customer service, location and atmospheric related store attributes are affecting the store format choice behaviour. The study has discussed various academic and managerial implications for retail industry in general and food & grocery in particular.
FOODBALT 2019 EVALUATION OF MICROBIOLOGICAL QUALITY OF COLOSTRUM

Bovine colostrum is an important source of different biologically active compounds: immunoglobulins, lactoferrin, lysozyme, lactoperoxidase etc., therefore vital for a dairy calf’s ability to survive. There is the lack of information about microbiological quality of colostrum. Still it is very important parameter, which can be significant for calf mortality and antibodies absorption rate, the aim of the study was to evaluate microbiological quality of colostrum obtained from Latvian cows. Colostrum samples (n=20, 50 mL) were collected in conventional farm with 500 cows (Zemgale, Latvia) during December 2018 to January 2019 one hour after calving. Samples were immediately frozen (-19±1 °C, within 30 min) and delivered to the laboratory. The colony forming units (LVS EN ISO 4833-1:2013) and presence of β-glucuronidase positive Escherichia col (LVS EN ISO 16649-2:2007) were detected in colostrum samples. Descriptive statistics were used for data analysis. The average total plate count of analysed colostrum samples was 5.62 log CFU mL, colony forming units ranged from 4.97 to 5.90 log CFU mL. In the current research β-glucuronidase positive Escherichia coli CFU ranged from >1 to 8300 mL in colostrum sample. Research results associated with low antibodies absorption rate by calf and high risk of diarrhoea in the farm.
New Insulin / GLP-1 RA Agents : Overview for the Pharmacist

Diabetes is a rapidly growing disease that is progressive in nature. Many medications are approved for the treatment of diabetes however, several novel agents show improved efficacy and safety over current therapies. In late 2016, two novel diabetic agents became available, insulin glargine and lixisenatide and insulin degludec and liraglutide. These medications combine basal insulin and a glucagon-like peptide-1 receptor agonist and were approved by the FDA to improve glycemic control in patients with Type 2 Diabetes Mellitus. Both products have shown benefits to patients during clinical trials. This review will discuss characteristics of each agent and where the use of these drugs may be implemented into current treatment guidelines.
Sensitivity of multiresistant bacteria and methicillin-resistant Staphylococcus aureus to ethanolic root extract of Raphanus sativus

Raphanus sativus L. (Brassicaceae) is an edible plant, whose root is consumed all over the world. The objective of this study was to test antibacterial potential of R. sativus ethanolic extract on 12 pathogenic bacteria including multiresistant bacterial strains and MRSA. All of the tested bacteria showed sensitivity to the antibacterial effect of R. sativus ethanolic extract with minimum inhibitory (MIC) and minimum bactericidal concentrations (MBC) in range of 15 μg/mL – 500 μg/mL. It is interesting to note that Raphanus extract showed the highest activity against multiresistant strain of Pseudomonas aeruginosa with equal inhibitory and bactericidal concentrations of 15 μg/mL, while the most resistant strain to the effect of the extract was Proteus mirabilis (MIC and MBC of the extract were 300 μg/mL and 500 μg/mL, respectively). In disk diffusion assay, zones of inhibitions were measured ranging from 8 mm to 22 mm.
Next-generation airport check-in process development from a market requirement perspective

Over the past two decades the check-in process went through a number of major changes, driven by the introduction of self-service technology that enabled to separate the various elements of the complete check-in and optimise each of these individual processes. However for airports to develop their check-in product, it is important to have a clear understanding of the market requirements, which is seen as a key driver for airport process development. Both passengers and airlines are increasingly in favour of self-service processes, however this largely depends on a number of factors including personal technological readiness, and the (perceived) ease of use and usefulness.
