THE EFFECT OF THE USE OF VIDEO AS A MEDIUM OF LEARNING ENGLISH TO IMPROVE STUDENTS' SKILLS IN WRITING PROCEDURE TEXTS
Authors: Helmi Helmi
Published: November 2019

The purpose of this study is to obtain evidence that there is an influence on the use of video on students' skills in writing procedure texts. This research was conducted in July 2019 in class IX of SMP Negeri 27 Banjarmasin. The method used is a quantitative method with a quasi-experiment design. The sampling technique used in this study is a purposive sampling method in which the researcher has had special consideration in choosing a research sample based on data provided by an English subject teacher at the school. The instrument used in this study is a test sheet that has been tested for validity and reliability. The two classes used as subjects in this study are called the experimental class and the control class which for the experimental class is taught through video and the control class is taught using audio media only by using speakers without image or visual display. The class that is an experimental group is a class that has a lower value than the pre-test results, so the researcher wants to prove whether video media can increase that value. The data obtained from the two experimental and control groups were tested for normality and homogeneity first and then the independent sample t-test was conducted. The results show that the significance value (2-tailed) from the analysis of independent sample t-test shows that the value is smaller than 0.05 where the value obtained is 0.00 so based on statistical decision in making provisions if the value is lower than 0.05 then there is a significant difference between the post-test results of students taught by using video and audio media only through speaker facilities in the ninth grade at SMPN 27 Banjarmasin.
Mitos del tiempo: exilios y retornos en la poesía de Luis Cernuda
Authors: NAVARRO RAMÍREZ Sergio
Published: November 2019

Este artículo estudia las distintas nociones y experiencias del tiempo en la poesía de Luis Cernuda posterior a la Guerra Civil española. El poeta sevillano elabora en sus poemarios diferentes mitos sobre el tiempo, buscando una temporalidad alternativa a la cronológica o a la histórica. Esta búsqueda está lejos de ser un mero juego intelectual, puesto que nace de una necesidad personalísima del poeta: la de superar la traumática experiencia del exilio. Así, veremos que las constantes y preocupadas reflexiones cernudianas sobre el tiempo buscan, en el fondo, una respuesta o una solución a los hechos de su biografía, descubriendo la conciencia temporal en el núcleo de las demás preocupaciones del poeta.
Decommissioning Planning for the Kinsale Head Gas Field, Offshore Ireland
Authors: Murray Michael
Published: November 2019

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.

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
Authors: Samudero Pandu , Capurso Valerio , Zoontjes Richard
Published: November 2019

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

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

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.

Published: November 2019

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

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.

Published: November 2019

A decrease in available farmland worldwide has prompted interest in polyculture systems such as intercropping where two or more crops are grown simultaneously on the same land to increase the yield per farm area. In Alcalde, NM, a year-round intercropping system was designed to evaluate organically produced blackberry cultivars (Rubus, subgenus Rubus) and winter greens in a high tunnel over a 2-year period. Two floricane fruiting blackberry cultivars, Chester Thornless and Triple Crown, were grown intercropped with ‘Red Russian’ kale (Brassica napus) and ‘Bloomsdale’ spinach (Spinacia oleracea) in a high tunnel. In an adjacent field, the planting of blackberry was repeated with no winter intercrop and no high tunnel. Both cultivars of blackberry were harvested July to September, and fresh weights were measured to determine suitability to the intercropping system in the high tunnel. Both species of winter greens were harvested January to April, and fresh yield weights were measured to discern fitness as possible intercrops in this system. Row covers were used for kale and spinach, and air temperatures were monitored November to April inside the high tunnel. High tunnel temperatures were within acceptable ranges for the production of greens with the use of rowcovers. Yield data from this study indicates that ‘Triple Crown’ blackberry outperformed ‘Chester Thornless’ blackberry in both the high tunnel and field trials with significant difference in the second season. Additionally, blackberry yields from both cultivars were observed to be higher in the field than in the high tunnel for both years. High temperature damage to high tunnel berry canes was noticed for both cultivars, with observed yield decreases in the second year in the high tunnel. Overall, this study indicates that the phenology and climate needs of the two winter greens and blackberry cultivars were not compatible for sustaining year-round organic high tunnel production.

Published: November 2019

Drought has become an important factor limiting crop yields in China. As an important greenhouse horticultural crop in China, the research of tomato (Solanum lycopersicum L. cv. Jinpeng No.10) is of great theoretical and practical significance. In the study, four different relative soil moisture contents (74% to 80%, 55% to 61%, 47% to 52%, and 25% to 30%) were used to induce drought stress. We investigated changes in photosynthetic gas exchange, chlorophyll fluorescence, and other related physiological parameters in response to different relative soil moisture contents. Drought inhibited the photosynthesis of tomato significantly, as shown by a clear decline in the net photosynthetic rate. Our results indicated stomatal limitation and nonstomatal limitation were responsible for the photosynthesis reduction.

Published: November 2019

The effects of bagging-induced light reductions on lycopene synthesis and the expression of related genes, antioxidant activity, and sugar composition of ‘Tubtim Siam’ pummelo (Citrus maxima) were investigated. Glucose, ascorbic acid, and flavonoid concentrations and 2, 2-diphenyl-1-picryhydrazyl scavenging activity were decreased in fruit covered with bags while still on the tree [0.01 μmol·m−2·s−1 photosynthetic photon flux density (PPFD)] compared with the untreated control (596.7 μmol·m−2·s−1 PPFD). The bagging treatment significantly decreased the temperatures on the surface in the bag. In addition, the bagging treatment decreased abscisic acid concentrations in the peel and pulp. However, the bagging treatment increased lycopene concentrations, upregulated phytoene synthase (CsPSY) and ζ-carotene desaturase (CsZDS) gene expressions; downregulated chromoplast-specific lycopene cyclase (CsβLCY), β-carotene hydroxylase (CsβCHX), and ε-ring hydroxylase (CsɛCHX); and decreased 9-cis-epoxycarotenoid dioxygenase (CsNCED1) gene expressions in the pulp. It is possible that maintaining a temperature of ≈25 °C in fruit covered with bags may increase the lycopene concentration in the pulp with the upregulation of CsPSY and CsZDS and the downregulation of CsβLCY, CsβCHX, CsɛCHX, and CsNCED1 gene expressions in the pulp.

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.
Dissipation-induced topological insulators: A no-go theorem and a recipe
Authors: Goldstein Moshe
Published: November 2019

Nonequilibrium conditions are traditionally seen as detrimental to
the appearance of quantum-coherent many-body phenomena, and much effort
is often devoted to their elimination. Recently this approach has
changed: It has been realized that driven-dissipative dynamics could be
used as a resource. By proper engineering of the reservoirs and their
couplings to a system, one may drive the system towards desired
quantum-correlated steady states, even in the absence of internal
Hamiltonian dynamics. An intriguing category of equilibrium
many-particle phases are those which are distinguished by topology
rather than by symmetry. A natural question thus arises: which of these
topological states can be achieved as the result of dissipative
Lindblad-type (Markovian) evolution? Beside its fundamental importance,
it may offer novel routes to the realization of topologically-nontrivial
states in quantum simulators, especially ultracold atomic gases. Here I
give a general answer for Gaussian states and quadratic Lindblad
evolution, mostly concentrating on the example of 2D Chern insulator
states. I prove a no-go theorem stating that a finite-range Lindbladian
cannot induce finite-rate exponential decay towards a unique topological
pure state above 1D. I construct a recipe for creating such state by
exponentially-local dynamics, or a mixed state arbitrarily close to the
desired pure one via finite-range dynamics. I also address the cold-atom
realization, classification, and detection of these states. Extensions
to other types of topological insulators and superconductors are also
discussed.

Flujos migratorios intrarregionales: particularidades, aportes y desafíos en la gestión diplomática regional
Authors: Batallas Lara Cosme
Published: November 2019

Los sistemas microeconómicos de los países sudamericanos se benefician de las transferencias económicas o remesas producto de la migración intrarregional. Estos envíos dinamizan las economías tanto en los países de origen como de destino. Se estima que a la fecha el número de personas en situación de movilidad humana en el subcontinente americano se ubica en el ordende los 41,3 millones de trabajadores migrantes, lo que en términos económicos representa una mayor demanda de bienes y servicios, aumento del consumo interno y reducción significativa del desempleo. Por lo tanto, los niveles de pobreza disminuyen, las condiciones de vida de las familias beneficiadas mejoran y los coeficientes de desigualdad socioeconómica se reducen. Debido alas políticas migratorias suscritas a nivel regional, los desplazamientos humanos entre los países sudamericanos se han incrementado considerablemente a partir de inicios del siglo veintiuno. La migración sur-sur hoy en día representa el 33 por ciento del total de movimientos migratorios circunscriptos geográficamente al interior del subcontinente americano. La migración sudamericana es predominantemente laboral y gira en torno a la oferta y demanda de mano de obra dominada principalmente por ciudadanos en edad productiva y aptos para el trabajo, amén de una importante incorporación del sexo femenino que dinamiza aún más la movilidad humana en Sudamérica.Los países que intervienen en calidad de mayores receptores de migración intrarregional son Argentina, Brasil y Chile, mientras que los emisores de migrantes de acuerdo al volumen de población movilizada son Bolivia, Paraguay y Uruguay.

Authors: Soenandi Iwan Aang
Published: November 2019

This reseach aimed to measure the mental workload of data entry processing tasks in the e-commerce industry based on mental workload value. It was to determine the factors influencing mental workload mainly induced by the data entry process. The experiments without work instruction and with two types of work instruction were conducted to diagnose the mental workload. The measurement of the initial mental workload condition of data entry employees was conducted in the laboratory. Then, the Electroencephalogram (EEG) measurement using sensors from Emotiv was performed every 30 minutes, and the data of EEG measurements (focus, engagement, and stress) were collected using the laptop. Meanwhile, pulse measurement (heart rate) was measured before and after the work. Raw National Aeronautics and Space Administration Task Load Index (NASA-TLX) and reaction time measurement were conducted after the work. Through these experiments, the researchers identify that mental effort and fatigue are the significant determinants of mental workload value in the data entry process of the e-commerce industry. In respect of the results of work performance analysis, it is recommended that the placement of work instruction should be near the employee. Then, the task demand (minimum completion target) should be adjusted according to each employee’s capacity.

Published: November 2019

Aiming at the problem of weak signal signature recognition of gear faults, a gear fault diagnosis method based on lifting wavelet packet and combined optimization BP neural network is proposed. The initial non-sampling prediction and update operators are calculated by Lagrange interpolation subdivision based on the principle of lifting wavelet, and the adaptive redundancy lifting wavelet packet decomposition and reconstruction algorithm is constructed. The network parameters of the number of hidden layers and the quantity of nodes, initial weights and thresholds of BP neural network are optimized by genetic algorithm (GA). The Levenberg-Marquardt (LM) algorithm is used to improve the search space of the network. Through experimental analysis, the results show that the gear fault diagnosis method proposed in this paper not only has high diagnostic accuracy, but also increase efficiency.

Solar energy is one of the widely used non-conventional form of energy. photo voltaic panels generate electricity and heat by absorbing solar irradiation. The performance of solar panels depends on several factors like dust accumulation on the surface, solar cell temperature, angle of inclination etc., To perform the cleaning action efficiently a semi-automatic cleaning mechanism has been designed and fabricated. The designed experimental setup consists of several nozzles attached on top of the solar panels and water is supplied to each nozzle using a Poly Vinyl Chloride (PVC) pipe frame connected to an AC motor operated with a time switch. Water flows on the surface of photo voltaic module, thus heat exchange takes place. One dimensional heat transfer analysis is performed and the results are compared to the experimental results for validation. The experiments were conducted at Bennett University, Greater Noida dated 9 October to 16 October. An increase in efficiency by 1.28 % to 2.65 % was reported in this experimental study.

Authors: Zhang Hougui , Ren Zhou , Zhang Huijuan , Liu Qiang
Published: November 2019

This paper discussed the effect of out-of-round wheels on simulation of rail dynamic behavior in the frequency range for ground vibration and ground-borne noise. A train-track interaction model was built by software Simpack and Abaqus. The input roughness was measured from a worn wheel and was applied moving on perfect smooth rail surface in different train speeds. Simulation results indicated that out-of-round wheel would affect the calculation result that could not be neglected, as the affected frequency range would be lower enough to influence the ground vibration (1-80 Hz) and ground-borne noise (16-250 Hz).

Pulmonary Hypertension Due to Left Heart Disease—Combine or Not Combined? DPG In or Out? A Practical Approach to the Patient With Suspected Left Heart Disease
Authors: Thenappan Thenappan
Published: November 2019

Pulmonary hypertension (PH) due to left heart disease (LHD) is the most common cause of PH in clinical practice. The definition and classification of PH-LHD has evolved in the last 5 years from the 5th World Symposium on PH (WSPH) in 2013 to the most recent 6th WSPH in 2018. Differentiation of PH-LHD, especially PH due to heart failure with preserved ejection from pulmonary arterial hypertension and chronic thromboembolic PH, can be very challenging. Finally, there is unclarity on the role of pulmonary vasodilators in the treatment of PH-LHD. The 6th WSPH consensus proceedings addresses all these topics in a detailed manner. In this article, we review the changes proposed by the 6th WSPH consensus proceedings in the definition, classification, diagnostic evaluation, and treatment of PH-LHD.
