Augmented Reality in Automotive Workshops: A Design Science Case Study

Augmented Reality (AR) is an evolving technology researched and applied in many areas to help support and guide work. One field in which the application of AR in practical usage is not common is automotive industry. To help minimize this gap, the presented research aimed to evaluate the need for AR in automotive industry and present an artefact applicable in simple workshop environments. Three semi-structured interviews with automotive technicians were performed to identify the issues encountered when working with connectors in a tight space and to design a prototype which could help mitigate them. The interviews highlight the need of a mobile AR tool within an industrial setting and the evaluation of the tool displays the benefits brought by introducing such technology in a workshop. An AR application has been developed and evaluated by mechanics and industry experts working with connectors in a case study, where the application was put to use to observe its effect on mechanics’ ability to solve workshop tasks. The findings showed that the usage of a mobile tool simplifies the task and decreases the time spent on assembly tasks by providing information on-spot. The study concluded that AR technology simplifies tasks such as identfiying markings on cable connectors and suggests that further research in this direction is needed to help further develop this area on a larger scale.
Pulmonary complications following cardiac surgery

Coronary heart disease is a common diseases of atherosclerosis. Despite the development of noninvasive therapies and the advancement of pharmacological methods and extensive drug regimens, coronary artery bypass grafting surgery is still the ultimate treatment option in many patients. Among the various complications following open heart surgery, one of the common difficulties is pulmonary complications associated with subsequent morbidity and mortality, which should be studied according to preoperative, perioperative, and postoperative factors. Preoperative factors include genetics, age, family history of pulmonary disease, smoking, coexisting disease, etc. Perioperative factors include surgical procedures like sternotomy incision, cardioplegia, and internal mammary artery harvesting; anaesthesia procedure effects like pulmonary collapse, maintenance drugs and morphine administration; and cardiopulmonary bypass pump by systemic inflammatory response syndromes. And finally, postoperative factors, especially mediastinitis and the role of nursing in the intensive care unit. Pulmonary complications after cardiac surgery include atelectasis, pleural effusions, pneumonia, pulmonary oedema, cardiogenic pulmonary oedema, acute respiratory distress syndrome, pulmonary embolism, phrenic nerve injury, pneumothorax, sternal wound infection, and mediastinitis, with different outbreaks in patients reported. Although the preoperative, perioperative, and postoperative factors play an important role in the occurrence of these complications, the preoperative factors, as factors that can be adjusted, should be considered more than the others and explained to the patient, and the preoperative patient’s assessment should be noted. Also, postoperative care with the goal of reducing infections and pulmonary complications should be addressed by the nursing team.
The Total Flavonoid Extract from Glycyrrhiza inflat Bat. Suppresses Atrophic Gastritis in Rats through the Akt/MAPK Pathway

Ethnopharmacological Relevance. Glycyrrhiza inflat Bat. is widely used to treat gastric ulcer and gastritis in clinic in China. Aim of the Study. To investigate the protective effects and possible mechanisms of the total flavonoid extract (TFE) from G. inflat Bat. on atrophic gastritis (AG) rats. Materials and Methods. The rat AG model was established by providing sodium deoxycholate and alcohol, and then, AG rats were treated with TFE for 30 days. Pathologic changes in gastric specimens were observed using hematoxylin and eosin staining, and the capability of gastric mucosa to secrete mucus was examined by alcian blue-periodic acid Schiff staining. Apoptosis induction in gastric tissues was measured by the TUNEL assay. The expressions of Bcl-2, Bax, and proteins in the Akt/MAPK pathway in gastric tissues were examined by immunohistochemistry and/or Western blotting. Results. Compared with the AG group, TFE attenuated the damage of gastric mucosa as reflected by the thickening of the lamina propria and the thinning of the muscularis mucosae. Moreover, TFE induced apoptosis in gastric mucosa with increasing Bax/Bcl-2 expression ratio. Concomitantly, the degrees of p-ErkThr202/Tyr204 and p-AktThr308 were decreased, whereas those of p-p38Thr180/Tyr182 and p-JNKThr183/Tyr185 were increased. Conclusion. We demonstrated the anti-AG effect of G. inflat Bat. in vivo and elucidated the underlying mechanisms that involve gastric mucosa protection through the Akt/MAPK pathway. The study provides a rationale for the application of G. inflat Bat. in the treatment of AG.
Effect of Wax Burn-Out Heating Temperature on The Compressive Strength of Casting Dental Alloy Investment

ABSTACT Aims: To evaluate the effect of the burn-out heating on the compressive strength of investment materials. Materials and Methods: Three commercial investment materials were used in this study. Seventy two cylindrical shape specimens were prepared to evaluate the compressive strength of the investment materials at room temperature (cold strength) and at two different burn-out heating temperatures : 700 C and 1000 C (hot strength).

Practical Issues of Integrating Advertising Data from the World Wide Web

The internet provides us with a large amount of information but the necessary information is often scattered among several sites even for the same type of data, which complicates search and analysis. This problem can be solved by creating information systems which acquire and aggregate data from the Web. The process of acquiring data can be difficult due to differences between various internet sites and the way they structure data, as well as the fact that these structures keep changing. The paper analyses the most important practical issues that have to be dealt with when creating information systems for acquiring data from the Web. The paper presents a system that aggregates UK commercial real estate advertisements from various internet sites and has been in use for several years. A demonstration of the methods used to resolve the issues is included.
Perceptual Modeling of Tinnitus Pitch and Loudness

Tinnitus is the phantom perception of sound, experienced by 10%–15% of the global population. Computational models have been used to investigate the mechanisms underlying the generation of tinnitus-related activity. However, existing computational models have rarely benchmarked the modeled perception of a phantom sound against recorded data relating to a person’s perception of tinnitus characteristics, such as pitch or loudness. This article details the development of two perceptual models of tinnitus. The models are validated using empirical data from people with tinnitus and the models’ performance is compared with the existing perceptual models of tinnitus pitch. The first model extends existing perceptual models of tinnitus, while the second model utilizes an entirely novel approach to modeling tinnitus perception using a linear mixed effects (LMEs) model. The LME model is also used to model the perceived loudness of the phantom sound which has not been considered in previous models. The LME model creates an accurate model of tinnitus pitch and loudness and shows that both tinnitus-related activity and individual perception of sound are factors in the perception of the phantom sound that characterizes tinnitus.
Determinants of Industrial Parks Performance in Ethiopia Emphasis on Bole Lemi Industrial Park

A recent phenomenon in Ethiopia, Industrial Parks (IPs) have been one of the pillars of industrialization in many East Asian and Latin American countries. This study aims at examining the determinants of Industrial parks short term operational performance in the Ethiopian context by taking the example of the first state run Bole Lemi Industrial Park. Although the determinants of short (static) and long (dynamic) term performance of Industrial Parks have already been identified world-wide, the same cannot be said in the context of Ethiopia. Hence, this study aims to fill in the literature gap by trying to identify the determinants of the operational performance of the first Public Industrial Park of Bole Lemi and study their effects on the overall short term operational performance of the Industrial Park. In order to do so, a cross-sectional study was conducted using both quantitative and qualitative methods where all eleven industrial units and all three government institutions found inside the IP have participated. Through a nonprobabilistic purposive sampling thirty six participants with a 70% response rate have participated in this study. The triangulation of descriptive statistics, binary regression results and interviews have shown that in the case of Bole Lemi IP, the determinants of short term operational performance in Bole Lemi are related to Industrial Park and national business environment and more specifically the high level of labour turnover and the absence of adequately skilled labor force.
Is the export-led growth hypothesis valid for Sri Lanka? a time series analysis

The export-led growth (ELG) hypothesis suggests that there is a strong positive linear relationship between a country’s exports and economic growth. For many years, theoretical and empirical studies have examined the causal relationship between exports and economic growth and found that this relationship is one of interdependence rather than of unilateral causation. This paper intends to investigate the casual effects of short and long run relationship between Export and Economic Growth and determine the recent trends, developments and obstacles Exports in Sri Lanka. The paper builds its analysis on the available literature on theoretical and empirical forecasting and applies on Sri Lanka Export Market. Annual time series data on Gross Domestic Production, Export, Gross fixed capital formation, employment and inflation, which cover the 1977– 2018 period, have been used in this study for the analysis. The data are taken from sources such as economic surveys of Sri Lanka, World Bank Reports, Central Bank Reports of Sri Lanka, UNCTAD (United Nations Conference on Trade and Development) Reports, and IMF reports. All data figures are expressed in rupees millions, unless otherwise percentage. The main purpose of this study employed empirical econometrics time series analysis Export –led growth hypothesis for Sri Lankan by testing using ADF unit root test, Johansen Cointegration test, Vector Error Correction (VEC) modelling and Granger casualty test. Ordinary Least Square method (OLS) is used to estimate and explain the regression model of the study. The findings of this article reveal that export which promotes economic growth, capital investment and employment in the shortand long-run for Sri Lanka. We find that the reported results confirm the validity of export-led growth hypothesis for Sri Lanka. That is, openness indeed leads to higher economic growth.
Estimating the Unofficial Income of Officials: The Case of China

While government officials in many countries take bribes and corruption hurts economic growth, estimating the size and prevalence of the unofficial income are difficult since bribes are largely unobserved. We propose a way to systematically estimate the unofficial income based on observed purchases of large-ticket items under the assumption of a stable relationship between large ticket purchases and total wealth. We apply this idea to China by using a detailed data set on house purchases in a city and the characteristics of the purchasers including legal income recorded in the social security fund. In our baseline specification, the amount of unofficial income for an average government official is estimated to be 67% of his or her official permanent income, and the unofficial income (as % of government salary) tends to increase steeply with the rank of the officials and the relative importance of government agencies. We also estimate that 23% officials may acquire unofficial income.
Chemical Compounds Isolated from Aerial Part of Primula auriculata L.

Arial parts of Primula genus (Primulaceae) are well known to treat various ailments in Iranian Traditional Medicine. Our preliminary studies showed that the medium polar to polar extracts of Primula auriculata had a significant cytotoxic activity and Induction of apoptosis effects on some cancerous cell lines. The current study focused on phytochemical investigation and characterization the compounds from P. auriculata active extracts. Dried and powdered aerial part of plant was macerated with petroleum ether, dichloromethane and methanol successively, for 24 hours, three times. Dichloromethane and methanolic extracts were separately examined by different chromatographic techniques such as VLC, CC and TLC to Fractionation and isolation compounds present in the plant extracts. The structures of purified compounds were elucidated on the basis of spectral data, particularly H-NMR and C-NMR experiments. 2-phenylchromone and 3,4,5-trihydroxy benzoic acid was identified for the first time from P. auriculata. In this research we have isolated compounds from pharmacological active extracts which is most likely responsible for cytotoxic action of P. auriculata. Further studies are required to determine activity and mechanism of action of isolated compounds.
Biochemical Changes in Renal Function and Plasma Protein Profile of Petrol Station Attendants in Basrah

The current study is aimed to evaluate the possible biochemical variation in renal functions and proteins of plasma due to exposure of petrol vapor. Thirty-six station attendant assessed in Basrah, Iraq. A corresponding (20), healthy persons were used as controls group. The results of our study have been shown a significant increase in the level of blood urea, blood creatinine and in the level of plasma protein for those workers from (6-10) years, when compared the results with the control group. The results refer to that exposure to petroleum products is cause imbalance in renal function. These results, from our study, may be directly related to the time of exposure.
Photosynthesis, growth, and yield of Paeonia ostii in tree-based agroforestry systems

Paeonia ostii T. Hong & J.X. Zhang, an emerging oil crop, was intercropped with 3-year-old plantations of pawpaw [Chaenomeles sinensis (Thouin.) Koehne], Chinese toon (Toona sinensis Roem.), and walnut (Juglans regia L.). In order to achieve a better production system, we studied the effects of intercropping on the photosynthesis, growth, and yield of P. ostii. The results showed that different pattern of agroforestry systems changed microclimatic and growing site conditions in comparison to the control treatment. The correlation analysis demonstrated that both similarities and differences were found in relationship between net photosynthetic rate (PN) and main ecophysiological factors at different treatments. Agroforestry systems significantly reduced transpiration rate and increased water-use efficiency (WUE), maximal quantum yield of PSII photochemistry, chlorophyll (Chl) a and total Chl contents, whereas there were no differences between PN, intercellular CO2 concentration, photochemical efficiency of PSII in the light, and plant height in these systems. The obviously exponential relationship between PN and PAR during a day were observed in Chinese toon and walnut treatments. The highest effective quantum yield of PSII photochemistry, electron transport rate, and photochemical quenching coefficient were observed in walnut treatment. The higher WUE and SPAD value, the thinnest stem, the biggest crown, the lowest stomatal conductance, and Chl a/b ratio as well as the fewest pods and harvest seed yield were observed in pawpaw treatment. In addition, there was a significant correlation between SPAD value and Chl (a+b) of P. ostii in agroforestry system. This study could be an important contribution for the science of land management in oil peony and other understory crops.
Buyer-Supplier Partnership Implementation: An Empirical Study of Small- and Medium-Sized Manufacturers

We describe the activities smalland medium-sized manufacturers (SME) undertake to improve the relationships with their suppliers. As a result SMEs fall into three distinct groups: 'strategic', 'non-strategic' and 'close, but adversarial'. Utilising significant differentiators we summarise characteristics within these groups and discuss implications for supplier partnership implementation in SMEs.
An Investigation on Vitamin B12 Serum Levels among Type 2 Diabetic Patients Treated with Metformin Compared to Normal Levels

Background: Given the increasing prevalence of type 2 diabetes in the community and the use of metformin as one of its most common therapies as well as presence of some evidences on a link between the use of this medicine and vitamin B12 levels, we decided to measure and compare serum level of vitamin B12 among the diabetic patients under treatment by metformin and compare with its natural content. Decreased Vitamin B12 levels leads to some clinical problems including anemia, gastrointestinal disorders (diarrhea, constipation, decreased appetite, etc.,), neurological disorders (tingle, numbness, muscle weakness, etc.,) and mental disorders (memory impairment, Original Research Article Samadanifard et al.; JPRI, 31(6): 1-9, 2019; Article no.JPRI. 53717 2 depression, behavioral problems, etc.,). Therefore, we would determine if the duration of metformin use and dosage may be effective on serum levels of vitamin B12 among metformin-treated diabetic patients. Methods: Serum vitamin B12 level in metformin-treated type 2 diabetic patients referred to Rasoule-Akram Hospital and Specialist Clinic of Taban in Tehran in 2016 (306 subjects selected by convenience sampling) was determined and then compared to its normal level. Results: Of the 306 participants in the study, 120 ones were females (39.2%) and 186 ones were males (60.8%). Also, 150 ones (49%) were healthy and 156 ones (51%) were suffering from diabetes Miletus. There was a significant difference between the type 2 diabetes mellitus and healthy individuals with quantitative variables such as age, height, weight, BMI, serum cholesterol (Chol) level, LDL serum level, HDL serum level, triglyceride (TG) level. The mean blood level of Vitamin B12 level was 448.92±156.75pg/mL among all participants. A Vitamin B12 deficiency frequency of above 6% was seen among diabetic patients. In regression analysis, a model was defined based on which age, gender, diabetes and Metformin used had a significant effect on serum levels of vitamin B-12. Also, none of the variables gender, age, duration of treatment, metformin quantity, weight and BMI was associated with a deficiency of vitamin B12. Conclusion: In the diabetic group, the prevalence of Vitamin B12 deficiency was more than6%. It was also seen that age, gender, diabetes mellitus, metformin intake and metformin content had a significant effect on serum B12 levels. Therefore, measurement of serum levels of vitamin B12 in metformin-treated subjects is recommended.
Organizing posted workers in the construction sector

In this chapter we look at trade union strategies for organizing posted workers in high-income European Union countries from the perspective of both unions and workers. We focus on construction as a sector characterized by highly fragmented labour relations, resulting from long and complex subcontracting chains and the use of agency workers, selfemployment and transient employment. The nature of the industry also presumes high rates of non-indigenous workers and makes it one of the most likely ones for fi nding posted workers (for more on posted work see Lillie and Wagner’s chapter in this book).
DISTRIBUTION OF IN-SITU AND SATELLITE DERIVED CHLOROPHLL-a AND TOTAL SUSPENDED MATTER IN THE SHALLOW MARINE ENVIRONMENT OFF BETUL-KARWAR

Remote sensing of ocean colour yields information on the constituents of sea water such as the concentration of phytoplankton pigments and suspended sediments (Chauhan et al., 2001). Satellite ocean-color data provide information about the spatial and temporal variability of near-surface chlorophyll-a concentration essential to study oceanic primary production, global carbon and other biogeochemical cycles (IOCCG, 2000). Measurements of ocean color and the fate of light in the ocean are extremely useful for describing biological dynamics in surface waters (Smith and Baker, 1989; Lorenzen, 1972; Yentsch, 1960). Thus, the oceanographic community has made its commitment to remote sensing of ocean color from space (Aiken et al., 1992; Mitchell, 1994). Chlorophylla (Chl-a) is often used for determining inland water trophic state and productivity (Gons, 1999; Gitelson et al., 2008).
