Published: October 2018

Abstract

Background and aims
Musculoskeletal pain may negatively affect work ability, especially when work demands are high and/or physical capacity of the worker is low. This study investigated the association between intensity of musculoskeletal pain in multiple body regions and work ability among young and old workers with sedentary and physical demanding jobs.

Methods
Currently employed wage earners (n=10,427) replied to questions about pain intensity, work ability, and physical work demands. The odds ratio (OR) for having a lower level of work ability in relation to the physical demands at work were modeled using logistic regression controlled for various confounders.

Results
The OR for lower work ability increased with higher pain intensity in all regions among workers with sedentary and physical work. The same pattern was observed among workers <50 years and ≥50 years in both work types. The association was quite consistent across age and work activity groups, although it tended to be more pronounced among those with physically demanding work in some of pain regions.

Conclusions
This study shows that increasing pain intensity in multiple sites of the body is associated with lower work ability. This was seen for both younger and older workers as well as those with sedentary and physical work.

Implications
Physical workers with multiple-site pain may especially be at increased risk of the consequences of reduced work ability. Therefore, extra attention is needed and this group may benefit from better targeted preventive measures.
Numerical Study of Unsteady Pulsed Suction through Endwall Bleed Holes in a Highly Loaded Compressor Cascade
Authors: Zhang Hongxin , Chen Shaowen , Wang Songtao , Wang Zhongqi 
Published: October 2018

Abstract
Unsteady pulsed suction (UPS) was applied as an unsteady flow control (UFC) technique in a certain highly loaded compressor cascade to control the flow separations. Only two bleed holes symmetrically mounted on the endwalls (one on the upper endwall and another on the lower endwall) were set up to achieve steady constant suction (SCS) and UPS. The improvements in aerodynamic performance by SCS and UPS under different time-averaged suction flow rates are firstly investigated and compared. The related unsteady aerodynamic parameters of UPS such as excitation frequency, excitation location, pitch angle, and skew angle are discussed and analyzed in detail. The results show that UPS can provide a better flow control effect than SCS with the same time-averaged dimensionless suction flow rate in the control of flow separation. The aerodynamic performance of compressor cascades can be significantly enhanced by UPS when unsteady aerodynamic parameters are in their optimum ranges. Based on the optimum parameters for UPS, the total pressure loss coefficient is reduced by 19 % only with the time-averaged dimensionless suction flow rate ms
=0.4 %.

Published: October 2018

Abstract
There is an increasing interest in the application of peroxygenases in biocatalysis, because of their ability to catalyse the oxyfunctionalisation reaction in a stereoselective fashion and with high catalytic efficiencies, while using hydrogen peroxide or organic peroxides as oxidant. However, enzymes belonging to this class exhibit a very low stability in the presence of peroxides. With the aim of bypassing this fast and irreversible inactivation, we study the use of a gradual supply of hydrogen peroxide to maintain its concentration at stoichiometric levels. In this contribution, we report a multienzymatic cascade for in situ generation of hydrogen peroxide. In the first step, in the presence of NAD+ cofactor, formate dehydrogenase from Candida boidinii (FDH) catalysed the oxidation of formate yielding CO2. Reduced NADH was reoxidised by the reduction of the flavin mononucleotide cofactor bound to an old yellow enzyme homologue from Bacillus subtilis (YqjM), which subsequently reacts with molecular oxygen yielding hydrogen peroxide. Finally, this system was coupled to the hydroxylation of ethylbenzene reaction catalysed by an evolved peroxygenase from Agrocybe aegerita (rAaeUPO). Additionally, we studied the influence of different reaction parameters on the performance of the cascade with the aim of improving the turnover of the hydroxylation reaction.

Abstract
Because of various convenient features, such as high manufacturing speed, cost effectiveness, and high strength at low ages, roller-compacted concrete (RCC) has found growing use in the construction of concrete pavements. This study investigated the effect of ground granulated blast furnace slag on the mechanical properties (compressive and tensile strength and modulus of rupture) of RCC at the ages of 28 and 90 days. For this purpose, 40 preliminary RCC mix designs based on slag contents of 0, 20, 40, and 60 % (by weight of cementitious materials), moisture contents of 4, 4.75, 5.5, 6.25 and 7 % (by total weight of cementitious materials and aggregates), and cementitious material contents of 12 and 15 % (by weight of aggregate) were devised and tested to determine the optimum moisture content for eight primary mix designs. The primary mix designs were used to make 144 specimens for the evaluation of targeted mechanical properties. The results showed that the moisture content that was needed to reach maximum compaction increased with increasing slag content. The highest strengths were observed in the specimens that contained 40 % slag, which all exhibited equal or greater strength than the corresponding slag-free specimens. The scanning electron microscope images showed that this difference can be attributed to the better filling of pores and cracks with small-sized slag particles, which outperform cement particles in this respect. It seems that there is an optimum level for replacing cement with slag in order to achieve improved strength and that exceeding this level will lead to strength reduction. In this study, this optimum level was found to be 40 % slag. Moreover, increasing the cementitious material content from 12 to 15 % was found to increase the compressive strength, tensile strength, and modulus of rupture by reducing the water-to-cement ratio.
A Novel Method for Evaluating Biaxial Stresses by Ultrasonic Critical Refracted Longitudinal Waves

Published: November 2018

Abstract
The ultrasonic critically refracted longitudinal wave (Lcr wave) method is an effective tool for measuring surface stresses in a nondestructive way. Whether the stresses are uniaxial or biaxial, the result of the measurements depends on the ultrasonic time-of-flight difference and the stress coefficient. Besides these, the measuring direction is also a factor to be considered. However, this method can only be used to determine the stress parallel to the direction of wave propagation without considering the influence of the stress perpendicular to the direction of wave propagation. After carrying out a large number of experiments, it was found that the stress perpendicular to the direction of wave propagation has a significant effect on the results obtained. Meanwhile, in a biaxial stress state, the proportional relationship that is obtained between the variation in the stress of the specimens and the variation in the time of flight of Lcr waves is not valid. Instead, the proportional relationship between the variation in strain and the ultrasonic time-of-flight difference is established. Based on the acoustoelastic effect and generalized Hooke’s law, the concept of a strain coefficient is proposed. The longitudinal wave acoustoelastic equation under a biaxial stress state is derived for further study. This equation is applicable to calculating uniaxial and biaxial stresses and provides an effective method for measuring biaxial stress fields on the surfaces of materials.
Comparison of Team and Participant Ratings of Event Dependence: Inferential Style, Cognitive Style, and Stress Generation
Authors: Scallion Laura M. , Cummings Jorden A. 
Published: October 2018

Introduction: Previous research has linked negative cognitive styles with stress generation. However, measures of cognitive styles have replied on ratings for hypothetical events, not experienced events. We examined the relationship between stress generation and attributional style for experienced events (i.e., inferential style) at both macro and daily levels. Methods: We measured stress generation in college students using the traditional objective team ratings (i.e., observer) as well as via participants’ own ratings (i.e., actor), which we argue captures more information and is consistent with calls for participant-centered research. Results: Cognitive style and inferential style positively correlated, indicating consistency between these two forms of assessment. Actor and observer identified events were significantly correlated for both dependent and independent events, suggesting that participants and teams are consistent in these categorizations. Results from both studies showed that inferential style was associated with actor but not observer identified dependent events. Discussion: Our findings provide some of the first evidence for the role of inferential style in actor identified stress generation and indicate that it is useful to examine both participant and observer ratings of stressful life events.

AbstrakKualitas udara sangat dipengaruhi aktivitas yang dilakukan oleh manusia. Penelitian ini bertujuan untuk mengetahui kualitas udara PM10, PM2,5, SO2 dan NO2 di dalam rumah di wilayah Cilegon serta aktivitas penghuni rumah dan gangguan pernapasan yang dialami penghuni rumah. Metode analisis data yang digunakan adalah uji statistik regresi linear untuk mengetahui hubungan antara kualitas udara PM10, PM2,5, SO2 dan NO2 dengan aktivitas penghuni rumah dan gangguan pernapasan. Penelitian ini ditemukan 9 rumah memiliki konsentrasi PM10 dan PM2,5 melebihi baku mutu yang ditentukan. Sebagian besar penghuni melakukan aktivitas merokok di dalam rumah dan kegiatan membakar sampah di pekarangan rumah, sehingga sebagian besar penghuni rumah mengalami gangguan pernapasan. Pada analisis regresi diketahui bahwa aktivitas penghuni rumah mempengaruhi konsentrasi PM10 sebanyak 24%, konsentrasi PM2,5 sebanyak 12%, konsentrasi SO2 sebanyak 2% dan konsentrasi NO2 sebanyak 4% serta konsentrasi zat polutan tersebut mempengaruhi gangguan pernapasan penghuni rumah sebanyak 25%. Aktivitas merokok di dalam rumah berhubungan dengan konsentrasi PM10 di udara dan gangguan pernapasan yang dialami oleh penghuni rumah berhubungan dengan konsentrasi SO2 di dalam rumah. Penelitian ini memberi penyadaran bahwa kualitas udara di dalam rumah penting diperhatikan untuk menjaga kesehatan penghuni rumah serta untuk memberi masukan bagi penghuni rumah agar mengurangi aktivitas yang dapat mengganggu kualitas udara di ruangan tertutup.Abstract The air quality is influnced by human activities. The aim of this research is to assess air quality of PM10, PM2,5, SO2, and NO2 in houses around Cilegon and occupant activities as well as respiratory disorders risk resulting from it. This research uses statistic test linear regression for data analysis to find the relationship between the air quality and the activity of house occupants and respiratory disorders. It was found that 9 houses having PM10 and PM2,5 concentration exceeds the quality standard. Moreover, most of the occupants smoke in their house and burn their waste and also have respiratory disorders. From the regression analysis, it was found that occupant activities inside their house impacted to 24% of PM10, 12% of PM2,5, 4% of SO2 and 4% of NO2 concentration, and those pollutant concentrations impacted to 25% of residents respiratory disorders. The smoking activity related to PM10 concentration while respiratory disorders related to SO2 concentration in the house. Those results can give a basis thought for further research which identify the influence of the air quality inside a house to other health disorders. This research also provides awareness that the quality of air in the house is important to take care of the health of the occupants and to reduce activities that can interfere with the air quality in the house or enclosed room.

Published: October 2018

BACKGROUND AND OBJECTIVES:
As outcomes for extremely premature infants improve, up-to-date, large-scale studies are needed to provide accurate, contemporary information for clinicians, families, and policy makers. We used nationwide New Zealand data to explore the impact of gestational age on health and educational outcomes through to adolescence.

METHODS:
We performed a retrospective cohort study of all births in New Zealand appearing in 2 independent national data sets at 23 weeks' gestation or more. We report on 2 separate cohorts: cohort 1, born January 1, 2005 to December 31, 2015 (613 521 individuals), used to study survival and midterm health and educational outcomes; and cohort 2, born January 1, 1998 to December 31, 2000, and surviving to age 15 years (146 169 individuals), used to study high school educational outcomes. Outcomes described by gestational age include survival, hospitalization rates, national well-being assessment outcomes at age 4 years, rates of special education support needs in primary school, and national high school examination results.

RESULTS:
Ten-year survival increased with gestational age from 66% at 23 to 24 weeks to &gt;99% at term. All outcomes measured were strongly related to gestational age. However, most extremely preterm children did not require special educational support and were able to sit for their national high school examinations.

CONCLUSIONS:
Within a publicly funded health system, high-quality survival is achievable for most infants born at periviable gestations. Outcomes show improvement with gestational ages to term. Outcomes at early-term gestation are poorer than for children born at full term.

In Cuba aproximately 38.000 ha of beans are sown in the Ministry of Agriculture, with a total production old to the state of 9.000 t. The highest porcentage belongs to state agencies under favorable environment and monoculture rotational system. The reminder is produced in agronomy cooperatives and by individual farmers; in all the cases yields are low. Experimental results obtained in the country, indicate that higher yields could be obtained. The main limiting factors affecting bean produce are: the lack of the areas devoted to this crop, low level of technology adoption and transference, poor availability of quality seed for the whole planted area and unefficient management of the harvest and post harvest. The conclusion is that there are agroecological and structural conditions, as wellas a great deal of research results, which allow to resort to the popularization of the crops, together with a sustainable territorial self-production of the grain for consumption and seed. To develope a broad base extension service program that allows the knowledge up-to-date of the producers and to keep the development of the national research programin permit to meet the availability for new technologies to face the diversity of problems involved in bean production.

Published: November 2018

The ethnobotanical study of plant species used for medicine by the Egun indigenous tribal group of Lagos State, Nigeria was undertaken with a view to assess the valuable plant species in the area and their methods of preparation. In the recent time, there have been a lot of ethnobotanical studies conducted among the varying ethnic compositions in Nigeria, but a gross dearth of such studies abounds among the Eegun ethnic composition. Several communities were selected, among which 10 respondents were randomly interviewed with the aid of a semi-structured questionnaire guide. Even more, in the LGA, a major market (Badagry market), was chosen where 5 botanical vendors were interviewed on the plant parts sold. A semi-structured questionnaire matrix was used to interview the respondents. All the interviewed were focused, conversational and two-way in communication. Group interviews were conducted in each community to established group consensus on the individual responses provided. The results revealed that a total of 44 plant species, belonging to 38 families, were observed to be valued for medicine and health maintenance. The respondents’ indigenous knowledge on these species revealed that diverse diseases were managed with the identified plant species. The parts of the plants used varied, as well as the methods of preparations which were simple, as well as the mode of utilization. Results obtained from the test on the abundance of the identified plant species used in the present study revealed that 7% of the identified species were very abundant, 41% were abundant, 41% were frequent, while 2% of them were rare. Adequate protection of medicinal plant resources through conservation in their natural reserves is recommended.
