Published: November 2019

In this study, it is aimed to determine the
relationship between student characteristics related to information technology,
the emotions of students and science literacy.
Descriptive research model was used. The sample of the study consists of
5895 15-year old students in Turkey. As a research instrument, the researchers
used the results of cognitive tests utilized by PISA in 2015 to assess
students’ science literacy skills. In this study, Turkish students are divided
into 2 groups. One of these groups who respond all questions about student
characteristics (High Emotional Intelligence) and another who does not respond
all questions about them (Low Emotional Intelligence). It was found that the
students with higher emotional intelligence have higher science literacy. The
results show that the emotions of the students, the information technology that
students have at home and the increase the number of this technology positively
affect higher science literacy.

Acacia auriculiformis est la troisième essence à croissance rapide la plus plantée au Bénin. Son bois, initialement destiné à l’énergie domestique, est de plus en plus utilisé comme bois d’œuvre. Ceci pourrait représenter une alternative durable à l’exploitation forestière des aires de conservation et contribuer à la séquestration de carbone. Cette étude avait pour objectif d’évaluer les facteurs qui influencent la production de bois et la séquestration de carbone des plantations de A. auriculiformis au Bénin. Douze plantations jeunes (4-7 ans), d’âge moyen (9-11 ans) et âgées (15-29 ans), réparties sur sols ferrugineux, vertiques, ferrallitiques et sableux dans la zone climatique guinéenne, ont été étudiées. Les paramètres mesurés étaient l’accroissement moyen en diamètre, le diamètre à 1,30 m, la hauteur du fût, la hauteur totale, la proportion de duramen et la proportion de bois sans défaut. La productivité est plus élevée sur sols ferrugineux et ferrallitiques, avec un accroissement moyen de 2,4 cm par an à 6 ans. Cet accroissement est significativement différent entre les arbres jeunes et les arbres âgés. La proportion de bois sans défaut est élevée sur sols ferrugineux. Par ailleurs, la séquestration de carbone est optimale à 20 ans. L’âge optimal pour la production de bois d’œuvre est d’environ 15 ans sur sols ferrugineux au Bénin. Le type de sol est le facteur le plus déterminant pour la production de bois de A. auriculiformis. Les sols ferrugineux représentent approximativement les deux tiers des sols rencontrés au Bénin, laissant présager de bonnes perspectives pour la filière de production de bois de A. auriculiformis. Toutefois, la caractérisation technologique de ce bois sur les différents sols au Bénin est nécessaire pour évaluer ses potentialités physico-mécaniques en bois de service.

Published: November 2019

Reading is one of four skills that is learned school. Reading is a process of how we find information from what we see. Like the other skills, reading comprehension is not easy. Students often face many problems in reading comprehension because of their limited ability and vocabulary in understanding readings materials. The researcher interested in students problems in reading comprehension of eleventh grade of SMA Negeri 6 Banjarmasin in Academic year 2017/2018. The objective of study is to describe the problems faced by the students of eleventh grade of SMA Negeri 6 Banjarmasin in reading comprehension. The researcher used descriptive quantitative research as the type of research. The population of the research was 253 and the sample was 71 students. The technique sampling is cluster random sampling. The instruments used were test-retest and questionnaire. Based on the research result, the students had two problems. There are finding main idea and guessing meaning from context. The mayor problem is guessing meaning form context and the minor problem is finding the main idea. From questionnaire, students had a problem in finding main idea and guessing meaning from context. Finally, it is suggested that for English teacher to improve reading skills and improve student’s vocabulary, word meaning, and knowledge about main idea in reading by providing more exercises in reading comprehension and active to find the meaning of the word that they found. The students should read English text not only in school but also read in outside school.
Decommissioning Planning for the Kinsale Head Gas Field, Offshore Ireland
Authors: Murray Michael 
Published: November 2019

Abstract
The Kinsale Head gas field offshore Ireland was discovered in 1971 and bought on stream in 1978. After 40 years of continuous gas production, a detailed plan for decommissioning of the field facilities is now being implemented.
Kinsale Head and a number of satellite gas fields, all operated by PETRONAS subsidiary PSE Kinsale Energy Limited, are the only producing facilities in the North Celtic Sea Basin, off the south coast of Ireland. The facilities include two fixed platforms, 10 subsea wells and extensive subsea infrastructure including 150 km of subsea pipelines and 80 km of subsea umbilicals, as well as an onshore reception terminal. Careful and innovative field management has extended the producing life from an originally estimated 20 years to over 42 years at time of Cessation of Production forecast to occur in 2020. The paper describes some of the methods used to prolong field operating life. Planning for decommissioning commenced in 2015-2016 and the paper describes the engineering and regulatory planning process followed. As this is the first-offshore field to be decommissioned in Ireland, extensive and detailed engagement with the regulatory authorities was undertaken prior to the submission of the decommissioning plan in 2018.
The paper demonstrates how a systematic and logical approach to both the regulatory approval process and the physical execution plan helps to de-risk the project. In particular, a comprehensive Environmental Impact Assessment (EIA) process was followed to underpin the selected strategy and to demonstrate a ‘best-in-class’ approach to the decommissioning program.
As part of the EIA process, a number of analytical techniques were used including Net Environmental Benefits Analysis (NEBA) and Comparative Assessment (CA); this is believed to be the first time these techniques were used for offshore projects in Ireland.

Abstract
In 2016, the gas monobore-completion wells were executed P&A as a pilot campaign to evaluate the technical feasibility and cost in the PTTEP’s setting. By following DMF’s guideline and PTTEP’s regulation, the cement bullheading uses as a method to isolate all hydrocarbon strata up to 30 m above the previous casing shoe. The gas-tight cement recipe is specifically designed for each well condition, then tested in the laboratory and approved by PTTEP prior proceeding the operation. After pumping job, the well shut-in for cement curing and developing strength. The cement must achieve the hydro test at 2,500 psi surface pressure. Otherwise, the contingency plan must be applied i.e. set two metal plugs above the topmost perforation and cover with 30 m of dumped cement.
In the first two wells, the pumping operations were completed as plan but failed the hydro test even surface samples had cured and shut-in longer than the testing time in the lab. The re-injectivity test was performed but not enough to redo cement bullheading. The contingency plan was applied to regain well integrity for P&A. It spent an extra 2 days and 100k USD per well. After revisited the cement design, the cause of failure is suspected by the temperature criterion in cement’s testing. Previously, the cement was tested in bottom hole static temperature (BHST) of the bottommost perforation which 45 °C higher than the BHST at the topmost perforation. It is possible that the cement at the top of perforation had not developed sufficient strength prior the test. Hence, the cement’s design criteria are revised. The UCS/UCA tests in BHST at the top perforation while the rest test in bottom hole circulating temperature (BHCT). The lab test reveals that cement rheology is quite thick but still pumpable. Furthermore, some wells require to shut-in up to 3 days before gaining the strength. So, the shut-in period after pumping is customized according to the lab test result. After applying this approach in 17 wells, 100% of cement bullheading jobs achieve the surface test and no need to apply the contingency plan. This contributes the cost saving 1.7 MMUSD over the campaign.
There are approximately 400 wells of PTTEP in the Gulf of Thailand that have high-temperature gradient and long reservoir section. These wells exactly require this approach to get success in cement bullheading, so the potential cost saving based on the previous price is about 40 MMUSD in the future.
Crane Suspended Transportation - An Effective Way to Remove Offshore Platforms

Published: November 2019

Abstract
Over the years, offshore decommissioning and abandonment has matured and become a considerable part of the portfolio of many offshore contractors. Nevertheless, there is a continuous effort to find innovative methods to create more economical and sustainable ways of working. One of the areas of development is the optimization of use of available equipment and crane capacity.
About a decade ago, Heerema Marine Contractors introduced an unconventional method to remove and transport large jackets. The jackets are lifted as one single piece and transported to the recycling yard whilst being suspended from both cranes of one of Heerema's Semi-Submersible Crane Vessels. Two purpose built gripper structures at the stern restrain the jackets from horizontal motions during transport. Benefits of this robust method are a shorter offshore project duration due to a reduced subsea cutting scope, and substantial cost savings due to reduction of subsea lifting tool and marine spread requirements. Besides this, safety of the operation is significantly improved due to fewer offshore activities and by preventing back loading operations to a barge at open sea.
A downside is that each jacket is different, which implies that adjustments have to be made to the gripper structures. Removal of topsides introduces additional complications, because structural strong points to attach the grippers are not always easily accessible due to protruding platforms and walkways. In an effort to find solutions to these challenges, Heerema investigated the feasibility of omitting the restraints when transporting the platform component to the recycle yard. This idea sounds simple and has been done before. However, it has a lot of implications. Opposed to a load which is horizontally restrained, a load freely suspended in the cranes significantly influences the vessel's motion behaviour, which makes the transportation more weather sensitive. To ensure the loads stay within the capacity of the cranes, numerous hydrodynamic calculations and simulations were performed to investigate the effect of expected environmental conditions on the behaviour of vessel and load.
The result is an effective removal method which is predictable, safe and time efficient. The method has been successfully applied for the removal of a number of structures (weighing up to 7000 mT) in the North Sea. Moreover, it has proved to offer substantial cost savings for installation of new-built structures by lifting straight from the quay of the fabrication yard and transportation to site suspended in the crane, as such eliminating the need for a barge transport.

Published: November 2019

Abstract
Background One of the main pathways for cadmium (Cd) transfer from the environment to the human body is through the consumption of leafy vegetables, and Brassica leafy crops tend to be Cd hyper-accumulators. But its response strategies to Cd still lack of systematic study. Results To investigate Brassica response strategies to Cd, we identified two cultivars with different Cd translocation efficiencies and performed mutli-transcriptomic sequencing studies under Cd treatments. Certain transporter families exhibited different temporal expression profiles in the two cultivars and may underlie the different Cd translocation efficiencies. Cd induced a drastic reduction of a 22 nt small RNA, the footprint of a pentatricopeptide repeat (PPR) protein on the chloroplast ndhB transcript and the concomitant down-regulation of the ndhB transcript. A global reduction in the expression of PPR genes was found, revealing previously unknown effects of Cd on organellar gene expression. Analyses of microRNAs (miRNAs) and their target genes by small RNA and degradome sequencing not only revealed Cd-induced changes in miRNAs but also implicated the existence of a regulatory cascade involving bra-miR156, its target gene, and bra-miR397 and bra-miR398 in Cd stress responses. Conclusions The present findings help uncover the impact of Cd stress on the transcriptome of B. parachinensis and provide candidate genes and miRNAs for further investigation.

Published: November 2019

Abstract
Background Alpha-1 Antitrypsin Deficiency (AATD) is a hereditary genetic disorder involving lungs in adults, characterized by low serum concentration of the protein alpha-1 antitrypsin (AAT). Several reports indicate that asthma is common in AATD patients, but there are only few data on respiratory function in asthmatic patients with intermediate AATD. The aim of the study is to evaluate lung function in asthmatic outpatients with AATD vs. asthmatic subjects without AATD.Methods We enrolled 57 outpatients affected by mild to moderate asthma from the University Hospital of Parma, Italy. We submitted to genetic analysis the asthmatic outpatients with a serum AAT concentration <113 mg/dL and those with relatives affected by AATD. Subsequently, the study population was split into AATD and not AATD subjects. We assessed lung function through a flow-sensing spirometer and the small airways parameters through an impulse oscillometry system.Results The values of FVC (% predicted) and of the RV/TLC (%) ratio were respectively lower and higher in patients with AATD vs. patients without AATD, showing a significantly greater air trapping (p = 0.014 and p = 0.017 respectively). Moreover, patients with AATD in comparison to patients without AATD showed lower FEV3 (% predicted) and FEV6 (L) values. A significant and positive correlation (p=0.041; r=0.894) occurred between the RV/TLC ratio and the years of smoking in the group of asthmatic patients with AATD.Conclusions AATD predisposes asthmatic heterozygote patients with PI*MZ, PI*MS and intermediate levels of AAT to small airways dysfunction and to increased values of pulmonary air trapping.

Abstract
Background:Renal transplant lithiasis is a rather unusual disease, and the recurrence of lithiasis presents a challenging situation.
Methods: We retrospectively analyzed medical history of the patient who surferred renal transplant lithiasis for two times, reviewed the relevant literature, and summarized the characteristics of this disease.
Results: We retrieved 29 relevant studies with an incidence of 0.34% to 3.26% for renal transplant lithiasis.The summarized incidence is 0.52%, and the recurrent rate is 0.082%. The mean interval after transplantation is 33.43±56.70 m.Most of the patients(28.90%) are asymptomatic.The management included percutaneous nephrolithotripsy(PCNL,22.10%),ureteroscope(URS,22.65%),extracorporeal shockwave lithotripsy(ESWL,18.60%) and conservative treatment(17.13%).In our case the patient suffered from renal transplant lithiasis at 6 years post transplantation, and the lithiasis recurred 16 months later. He presented oliguria,infection or ARF during the two attacks, but without pain. PCNL along with URS and holmium laser lithotripsy were performed.The patient had even recoveries after surgeries,except for a 3mm residual stone in the calyx after the second surgery. He had normal renal function without any symptom,and was allowed to discharge with oral anti-calculus drugs and strict follow-up at clinic.Fortunately, the calculus passed spontaneously about 1 month later.
Conclusions: Due to lack of specific symptom in early stage, patients with renal transplant lithiasis may be delayed for diagnosis and present ARF. Minimally invasive treatment method was optimal,and combined usage of two or more procedures are beneficial for patients. After surgery taking anti-calculus drugs, correcting metabolic disorders and avoiding UIT are key measures to prevent the recurrence of lithiasis.

Published: November 2019

Abstract
Background: Empirical antibiotic therapy often fails to cover all pathogens for patients with critical infection without pathogen identification. In these patients, progressive infection can manifest as a “procalcitonin (PCT) alert”. Delayed proper antibiotic escalation could worsen their prognosis. We hypothesized that for these patients, escalating antibiotics after a “PCT alert” would improve their outcomes.Methods: This was a single-center retrospective study including patients with suspected infection who were admitted to Peking Union Medical College Hospital from January 2014 to June 2018. Patients were labelled as “antibiotic escalation” or “nonescalation” according to their antimicrobial use 48 h before and after the "PCT alert". “PCT alert” was defined as PCT ≥1.0 ng/mL that had not decreased by at least 10% from the previous day or from baseline, or a single measurement ≥ 1.0 ng/ml. Indicators that possibly influenced the prognosis were collected. 28-day intensive care unit (ICU)-free days were calculated; ICU stays >20 days and ≤20 days were considered nonprolonged ICU stays (nPISs) and prolonged ICU stays (PISs), respectively. Difference analysis and binary logistic regression were performed to determine the factors that influenced the 28-day ICU-free days . Results: A total of 1109 patients were included, 654 in the PIS group, other 455 in nPIS group. The PIS group had higher rates of pathogen identification (33.94% vs 28.13%, P=0.047) and escalated antibiotic therapy (35.47% vs 20.66%, P<0.001) but a lower proportion of surgical patients (39.45% vs 54.95%, P<0.001) than the nPIS group. Regarding PCT, the values on the 1st day (20.36±43.89 vs 14.89±30.37 ug/L, P=0.014) and on the “alert day” (24.24±46.38 vs 18.75±32.69 ug/L; P=0.021) were higher in the PIS group than nPIS group, but no significant difference in the white blood cell (WBC) count was revealed. According to the binary logistic regression model, antibiotic escalation (OR=0.552, 95% CI 0.347-0.877, P=0.012) was a negative factor for PIS, while postsurgical status (OR=1.959, 95% CI 1.269-3.023, P=0.002) and age (OR=1.020, 95% CI 1.007-1.034, P=0.003) were positive factors. Conclusions Escalating antibiotics in high-risk infection patients whose PCT does not decrease expectedly after administering broad-spectrum antimicrobials may reduce their ICU stay.
Isolation and Activity Determination of Enzyme Phosphatase Secreted by Aspergillus niger
Authors: Zharare Tafadzwa , Mangoyi Rumbidzai 
Published: November 2019

The use of enzymes on industrial scale saves a lot of energy and avoids pollution, thus holding a promise for green and economically sustainable alternative strategies in industrial transformations. Generally, the fungi Aspergillus niger secretes enzymes which can be used in different industries. Thus, coming up with these enzymes in large amounts will definitely result in reduced costs encountered in importing them for industrial use. This study focussed on isolation and activity determination of an enzyme phosphatase secreted by Aspergillus niger. This enzyme can be of great importance in molecular biology industries, particularly for recombinant DNA technology. For this study, pure cultures of Aspergillus niger were used. Aspergillus niger was resuscitated on potato dextrose agar and then subcultured in Adam’s medium, a medium specific for the production of phosphatase. Cells were centrifuged and the filtrate was collected whilst the residue was discarded. The filtrate was expected to contain the crude enzyme phosphatase since Aspergillus niger secretes the extracellular enzyme into the medium. Disodium phenyl phosphate was used as a substrate for the determination of the phosphatase activity. The enzyme activity was determined spectrophotometrically by reading absorbance of phenol formed in the presence of enzyme and the substrate. The concentration of phenol liberated was then used to calculate the enzyme activity expressed in King Armstrong Units (KAU). Further work on enzyme activity determination was done by varying enzyme and substrate concentrations. Results showed that the isolated alkaline phosphatase had activity of 4.0 KAU and 4.5 KAU at 25 ºC and 37 ºC respectively. Acidic phosphatase had activity of 5 KAU and 7 KAU at 25 ºC and 37 ºC respectively. Rate of activity increased upon increasing enzyme concentration and substrate. Thus, Aspergillus niger produces the enzyme phosphatase, however, there is need to induce the production of these enzymes for industrial use.
