Seismic Analysis of Double Deck Floating Roofs of Siraf Storage Tanks with Condensate, Light and Heavy Crude Oils

Seismic vibration of double deck floating roof of Siraf storage tanks located in southern Iran has been studied. Condensate of Nar and Kagan gas field in south of Iran as a very light hydrocarbon, Lavan as light and Soroosh as heavy crude oil content have been chosen. In addition to fluid-structure interaction, intermediate stiffeners, foam seal with nonlinear radial compression behavior and contact friction between the seal and the inner side of the wall are also considered. Under the above conditions, modal and time history analysis has been performed. For time history analysis, Sarpol-e Zahab and Shonbeh earthquakes in Zagros seismotectonic province of Iran and Sakaria as an earthquake near Iran were selected. Dominant natural frequencies, mode shapes of the roof parts and damping ratios of the first and second natural frequencies in addition to overall and spectral behavior of the roof in each liquid cases were obtained and discussed. Changing condensate to Soroosh oil made about 17% hydroelastic natural frequency decrement and about 10% damping ratio decrease for the first natural frequency. The results showed that dominant natural frequencies and the relevant damping ratios decrease with moving from light to heavy liquid. Vibration of the roof fundamentally depends on the frequency content of earthquake in relation to such natural frequencies. Also, floating roof in heavier liquid is more vulnerable to vibration according to the scaling method and steady state amplitude.
Evaluation of Lettuce (Lactuca sativa L.) Production under Hydroponic System: Nutrient Solution Derived from Fish Waste vs. Inorganic Nutrient Solution

Organic fresh products are appreciated and are gaining a good reputation regarding human health and environmental concerns. Despite the fact that hydroponics are commonly used in vegetable production, growers are looking for sustainable cultivation systems. Therefore, the objective of this study was to investigate the effect of using an organic-based nutrient solution (NS) derived from fish waste in a hydroponic system on the vegetative growth and production of lettuce compared to a conventional inorganic NS. Plant growth, yield, physiological and nutrient content parameters were determined. The results revealed that the overall growth and fresh biomass of the organic NS grown lettuce were relatively lower than those of the inorganic NS. Stomata density was significantly higher in inorganic grown lettuce compared to the organic one. However, the total chlorophyll, carotene, phenolic compounds, and flavonoid contents, as well as antioxidant activity were significantly higher in lettuce grown in organic NS compared to the inorganic one. Leaf nutrient content at harvest was significantly impacted by the type of used fertilizer. Based on these findings, in hydroponic system, organic liquid fertilizer derived from fish waste (as an alternative NS source) requires further improvements to achieve optimal growth and yield comparable to that of conventional inorganic NS.
Equity home bias and consumption-real exchange rate puzzles: A joint solution

In a standard dynamic stochastic general equilibrium model with a complete asset market, home agents should hold a foreign equity biased portfolio to hedge the non-traded labor income risk, which contradicts home equity biased portfolios observed worldwide. As the labor income share increases, the degree of home bias should decrease because there is more incentive to hold foreign equity. In the data, there is not any evidence that the labor income share and the degree of home bias are negatively correlated. The standard model also predicts that the consumption diﬀerential-real exchange rate correlation is positive, while it is negative in the data. I show that a combination of market incompleteness, non-tradable goods, and labor supply can explain the three features above. My model can generate a large equity home bias, despite the strong positive correlation of non-traded human capital return with domestic equity return. The home bias is not sensitive to the labor income share. The consumption diﬀerential-real exchange rate unconditional correlation generated by my model simulation is zero.
Perceived Ease of Use on Purchase Intention of Mobile Commerce Application

The use of mobile commerce applications by consumers in the process of online buying and selling activities in Indonesia is still low, which happens because of a lack of interest in using mobile commerce applications. Therefore, this study was conducted to obtain an overview of the effect of perceived ease of use simultaneously or partially on the interest in using mobile commerce in Indonesia. The method used in this study was an explanatory survey with the object of e-commerce consumer research in Indonesia with a sample size (n) of 400. The sampling technique used was the simple random sampling and the result showed that perceived ease of use had an effect on interest in the using the mobile commerce applications. The results of the study showed that Indonesian e-commerce consumers considered the importance of perceived ease of use before using mobile commerce applications because it is related to consumer behavior about how individuals wish to use a system that provides convenience.
Risk Factors for Cryptococcal Meningitis Recurrence in Human Immunodeficiency Virus (HIV)-Infected Patients in a Large Chinese Acquired Immune Deficiency Syndrome (AIDS) Treatment Center

Background Cryptococcal meningitis (CM) is one of the most common opportunistic neuroinfections in patients with HIV. Most studies have focused on non-HIV CM and there are only a few studies on HIV CM in China. The purpose of the present study was to evaluate the characteristics and risk factors for CM recurrence in patients infected with HIV in the Chongqing Public Health Treatment Center in China. Material/Methods From January 2014 to December 2017, all patients with CM aged 18 years or older were enrolled and a case-control study was performed to determine the risk factors associated with recurrence of CM. Antimicrobial susceptibility was determined with a fungal drug sensitivity kit and the sequence types (STs) were analyzed with multilocus sequence typing. Results The incidence of CM in the 5185 HIV-infected patients was 3.5% (179). Follow-up data were available for 82 of the patients for whom complete medical records were available and they were included in the present study. There were 7 STs among 82 Cryptococcus neoformans isolates; ST5 and ST31 were the most prevalent genotypes. Testing showed that C. neoformans had high sensitivity to 5 antifungal drugs and no differences in resistance were observed, even when different STs were tested. Risk factors for recurrence were analyzed in 69 patients, excluding those who died. The results of multivariate analysis showed that only hospital stay was associated with recurrence of CM. Conclusions Our results indicated that combining education about medication with clinical treatment could help prevent recurrence of CM.
Improved analysis of sinigrin in Ethiopian mustard

Summary An ion-pair reversed-phase high-performance liquid chromatography (HPLC) method was developed for the analysis of sinigrin in Ethiopian mustard (Brassica carinata A. Braun) seed and seed fractions. Separation was compared on several RP-HPLC columns (Inertsil® ODS-4 C18 and ZORBAX® Eclipse XDB-C18) with an isocratic eluent containing 100% aqueous (aq.) tetramethylammonium bromide (10 mm, pH 5.0). Sinigrin retention was affected by HPLC variables including the type of ion-pair reagent, buffer strength and pH, acetonitrile concentration, column temperature and eluent flow rate. Partial validation demonstrated this optimised chromatographic condition to be linear, accurate and precise. Multistage extraction using 70% (v/v) aq. methanol was more efficient than 50% (v/v) aq. acetonitrile. In addition, the matrix effect and recovery rate as well as processing efficiency of the analytical protocol were determined. This method is suitable for high throughput analysis of sinigrin in Ethiopian mustard seed and seed fractions.
Incorporation of organic groups on the surface of multi-walled carbon nanotubes using an ultrasonic tip

ABSTRACT Multi-walled carbon nanotubes (MWCNTs) have been used to solve problems in different fields due to their mechanical, electrical and nanometric properties. However, the tendency of CNTs to agglomerate, and their poor interactions with other molecules have hindered their use. Accordingly, CNTs have been modified mainly by heating under reflux with strong acids or bases, in some cases for up to 72 h. In this study, the surfaces of MWCNTs were modified with 1,4-diaminobutane dihydrochloride (DB) and oxalic acid dihydrate (OX) using an ultrasonic tip (25 mm) at 20 kHz and a temperature of 67–80°C. Three different ultrasound times were employed: 20, 32 and 64 min. The most significant changes to the MWCNTs were observed when they were modified with DB (N 1s (11.05%) and Cl 2p (1.01%)) and OX (C 1s (74.69%) and O 1s (25.31%)) at 20 min, 68°C and 32 min, 70°C, respectively.
Development of Kenaf (Hibiscus Cannabinus L.) Pedigrees with Superior Characteristics through Backcross

Multipurpose utilization, including as rope, pulp, and filtration media, is what makes kenaf ( Hibiscus cannabinus L.) special. This experiment was conducted to select elite pedigrees with high biomass production through backcrosses. The agronomic performance, fuel characteristics, and histological analysis of the elite lines were investigated at the BC 1 F 2 generation in comparison with the Control. Significant differences were observed in 12 evaluations of variety and pedigrees. Five plants, including the two Controls (Jangdae and Hongma300) and three pedigrees, showed a large difference in the number of flowering days from July 5 to September 30. The plant height of BC100-10 (447 cm) was the highest among the genotypes. Regarding branch number, BC100-15 showed the best performance with 29 branches. Stem dry weight was found to be the lowest in Jangdea at 792 g, whereas BC100-17 showed the highest dry weight. Hongma did not set seeds owing to late flowering. However, with 34 g/plant on average, three elite lines had more seeds than Jangdae (16 g/plant), which are vulnerable to decay owing to viviparous germination. In the fuel characteristics analysis, the heating value of the three elite lines ranged from 4,510 to 4,930 kcal/kg, which was much higher than that of the two Controls (4,320 kcal/kg). The ash content analysis indicated the lowest value at 3.2% for the line BC100-10, which was similar to Korea’s 3 rd -grade. Based on the histological analysis of the stem, the pedigrees were close to Hongma. Taken together, these three elite lines would be useful as genetic resources for high biomass production.
COMPARATIVE EFFECTIVENESS OF ROBOT-INTERACTIVE GAIT TRAINING WITH AND WITHOUT ANKLE ROBOTIC CONTROL IN PATIENTS WITH BRAIN DAMAGE

Although ankle robotic control has emerged as a critical component of robot-interactive gait training (RIGT), no study has investigated the neurophysiological and biomechanical effects on ankle muscle activity and joint angle kinematics in healthy adults and participants with brain damage, including stroke and cerebral palsy (CP). This study compared the effects of RIGT, with and without ankle control actuator, on ankle muscle activity and joint angle kinematics in healthy adults and participants with brain damage. Ten patients ([Formula: see text], left hemiparetic [Formula: see text], [Formula: see text]) underwent standardized surface electromyography (EMG) neurophysiological and kinematics biomechanical tests under the RIGT with and without ankle control actuator conditions. Outcome measures included the EMG amplitudes of the tibialis anterior and gastrocnemius muscle activity, and ankle movement angles recorded with a two-axis digital inclinometer. Descriptive statistical analysis demonstrated that RIGT with ankle control actuator showed superior effects on EMG (30%) and kinematics angles (25%) than RIGT without ankle control actuator. Our results provided novel, promising clinical evidence that RIGT with ankle control actuator can more effectively improve the neurophysiological EMG data and ankle dorsiflexion and plantarflexion movements than RIGT without ankle control actuator in participants with stroke and CP.
EFFECTS OF JUST-IN-TIME PROCUREMENT STRATEGY ON ORGANIZATION PERFORMANCE OF FOOD AND BEVERAGE MANUFACTURING FIRMS IN NAIROBI COUNTY, KENYA

Purpose: The objective of this study was to investigate the effects of Just-in-time procurement strategy on organization performance of food and beverage manufacturing firms in Nairobi County. Methodology: The study adopted a causal research design. To collect primary data the respondents answered questions administered to them through questionnaires. The unit of observation consisted of the Heads of Procurement, Production, Sales and Finance of the food and beverage manufacturing firms located in Nairobi County as listed by Kenya Association of Manufacturers in 2019. The sample size was 83 heads of department. Face validity was used to determine the accuracy of the study instrument while test re-test method was used to determine the reliability. The completed questionnaires were analysed with the aid of Statistical Package for Social Sciences. Data was analysed using descriptive and inferential statistical techniques. Findings: From the study findings Just-in-time (JIT) procurement strategy (β=0.689, t=3.469, p=0.001) had a positive effect on organization performance of food and beverage manufacturing firms. The value of adjusted R2 was 0.167 indicating that there was variation of 16.7 percent on organization performance due to changes in JIT procurement at 95 percent confidence interval. Conclusion: The study concluded that JIT Procurement strategy has a positive effect on organization performance of food and beverage manufacturing firms in Nairobi County. The overall effect of JIT Procurement strategy on organization performance was 68.9%. The study therefore accepted the alternative hypothesis that JIT procurement strategy has significant effect on organization performance of food and beverages manufacturers in Nairobi County. Unique contribution to theory, practice and policy: Food and beverge manufacturing firms in developing countries should consider implementing JIT Procurement strategy. This will ensure that they purchase the optimal level of items when needed to avoid keeping unnecessary inventory which ties up money and at the same time ensure that there is no shortage so that the customers have to wait. Policy makers in the food and beverage manufacturing sector should consider developing policies to promote JIT Procurement strategy in this industry. Further research should be conducted focusing on the service sector to investigate the effect of JIT Procurement strategy on organization performance for comparison.
Nitrogen Use Efficiency and Excretion in Grazing Cows with High and Low Milk Urea Nitrogen Breeding Values

Milk urea nitrogen content is moderately heritable and is phenotypically related to urine nitrogen (UN). Based on this relationship, it has been suggested that genetic selection for lower milk urea nitrogen in grazing dairy cows could decrease UN concentration thereby reducing nitrogen excretions into the ground. The objective of this study was to compare the nitrogen use efficiency (NUE) and excretion in grazing cows with high and low milk urea nitrogen breeding values (MUNBV) in two farms of contrasting farming intensity. On the high-intensity farm (HIF) 68 and 70 cows with low and high MUNBV, respectively, were fed higher levels of supplementation and milked twice-daily, while on the low-intensity farm (LIF) 82 and 86 cows with low and high MUNBV, respectively, were fed lower levels of supplementation milked once-daily. Nitrogen use efficiency (g/g) was calculated as the ratio of daily milk N to daily N intake. Daily N intake (g/day) was derived from feed intake estimates based on energy requirements. The UN (g/day) was estimated by back-calculation from dietary N and subtracting milk N, faecal N, and N retained in body tissues. Irrespective of farm, cows with low MUNBV had significantly lower MY and milk urea nitrogen (p < 0.001) but this was not linked to significantly less UN. In the LIF, cows with low MUNBV had lower NUE (p < 0.001) than cows with high MUNBV, and this was explained by the reduced protein yield (p < 0.001). Selecting cows for low MUNBV was not an effective tool to reduce N losses and to increase the NUE in two dairy farms of contrasting farming intensity.
Accuracy of non-invasive body temperature measurement methods in critically ill patients: a prospective, bicentric, observational study

Objective: The accuracy of different non-invasive body temperature measurement methods in intensive care unit (ICU) patients is uncertain. We aimed to study the accuracy of three commonly used methods. Design: Prospective observational study. Setting: ICUs of two tertiary Australian hospitals. Participants: Critically ill patients admitted to the ICU. Interventions: Invasive (intravascular and intra-urinary bladder catheter) and non-invasive (axillary chemical dot, tympanic infrared, and temporal scanner) body temperature measurements were taken at study inclusion and every 4 hours for the following 72 hours. Main outcome measures: Accuracy of non-invasive body temperature measurement methods was assessed by the Bland–Altman approach, accounting for repeated measurements and significant explanatory variables that were identified by regression analysis. Clinical adequacy was set at limits of agreement (LoA) of 1°C compared with core temperature. Results: We studied 50 consecutive critically ill patients who were mainly admitted to the ICU after cardiac surgery. From over 375 observations, invasive core temperature (mostly pulmonary artery catheter) ranged from 33.9°C to 39°C. On average, the LoA between invasive and non-invasive measurements methods were about 3°C. The temporal scanner showed the worst performance in estimating core temperature (bias, 0.66°C; LoA, –1.23°C, +2.55°C), followed by tympanic infrared (bias, 0.44°C; LoA, –1.73°C, +2.61°C) and axillary chemical dot methods (bias, 0.32°C; LoA, –1.64°C, +2.28°C). No methods achieved clinical adequacy even accounting for significant explanatory variables. Conclusions: The axillary chemical dot, tympanic infrared and temporal scanner methods are inaccurate measures of core temperature in ICU patients. These non-invasive methods appeared unreliable for use in ICU patients.
A Liberal Region in a World of Closed Borders? The Liberalization of Asylum Policies in Latin America, 1990–2020

Recent scholarship has claimed that countries across Latin America have been adopting an increasingly liberal and more advanced legal framework for the protection of refugees. Yet little systematic cross-country evidence beyond case studies exists to back up this claim. To address this gap in the literature, I develop a new methodology — called the Asylum Policies in Latin America (APLA) Database — to measure policy outputs on asylum across Latin America over time. Applying this new methodology, I present the results of the codification of 19 Latin American countries, over a 31-year period (1990–2020), using 65 indicators to track the development of policy measures on asylum. The findings from this new database confirm the claim from existing research that countries across Latin America have developed an increasingly complex and more liberal legal framework for the protection of refugees. This liberal trend in asylum legislation stands in contrast to findings of increased restrictiveness over the same period across OECD countries. The APLA Database represents a unique contribution to the fields of migration and refugee studies, as it provides systematic data on the nature and development of asylum policies in Latin America through highly disaggregated data on policy outputs. Additionally, APLA demonstrates the existence of intra-regional variation. It also allows scholars to develop and test hypotheses in the field of asylum studies and provides a reference database for comparative analyses of asylum policies in Latin America, as well as a framework for the comparative study of asylum policies across the globe.
Role of Employee Behaviour and Job Stress on Work-Life Balance: A Case of HEIs of Pakistan

The study aims to identify how workplace stress and employee behaviour impair the work-life balance of faculty members of Higher Education Institutes in Karachi, Pakistan. This study has included a quantitative survey research design. The study collected 386 sample responses from faculty members using the purposive sampling technique. The PLS-SEM analysis was used for data analysis through SmartPLS version 3.2. 9. The results have shown that employee behaviour has a positive and significant effect on ER, IR, and WLB; workplace stress has a positive and significant effect on anxiety; workplace stress has a positive and significant effect on time stress, and workplace stress has a negative and significant effect on work-life balance. Furthermore, the study recommends using person-centered stress management techniques for possible work-life stress and employee well-being. Offering relaxation/care exercise classes, enabling wellness, and supplying facilities, such as gymnasiums, encouraging safe living, healthy eating options, and providing guidance are just a few examples. This study is significant for employee’s well-being because the findings will allow them to understand and negotiate their roles throughout the family and work-life. By understanding the importance of WLB, employees would be able to introspect themselves to cope with their job and relationship management. Similarly, management can identify career stages and help employees with the development tasks they experience at each stage. Lastly, the study implications accentuate that by formulating appropriate strategies, management can help employees and retain them as essential organizational assets.
