Published: April 2018

This study aims 1) to know the implementation of thematic learning on the curriculum 2013 in 4th-grade elementary school; 2) to know the needs of teachers in the implementation of thematic learning in 4th-grade elementary school. This study used qualitative research methods. The research was conducted in public elementary schools in the Gugus Pattimura, Klaten district which has been using the curriculum 2013. The subjects of the study were 4th-grade elementary school teachers. The data used to collect data is in-depth interviews, observation, and document analysis. The results of this research are: 1) All teachers have implemented thematic lesson in curriculum 2013. There are some teachers who still have difficulty in the implementation. Difficulties experienced by teachers, among others, in the making of the lesson plan, the implementation of thematic learning, assessment process, and develop the material in every learning. This is because of the needy costs, the amount of time required, and the teacher has other work to do besides teaching; 2) On the implementation of thematic learning, teachers still need other references to deepen the material and to develop the ability of learners to be more independent in learning activities and tailored to the competencies that must be achieved. The second requirement is that teachers need adequate facilities for the implementation of thematic learning can be maximized. In addition, teachers need regular coaching on the implementation of thematic learning so that learning activities can be given to learners maximally.

Published: April 2018

* Interposition nerve grafting and tendon transfer lead to suboptimal functional and sensory recovery after proximal upper-extremity nerve injuries. Techniques to treat proximal nerve injuries are evolving, with growing use of distal nerve transfers to reduce recovery delay and achieve reinnervation before permanent muscle loss.

* Patients undergoing distal nerve transfer for treatment of peripheral nerve pathology have improved functional results compared with patients who undergo traditional nerve grafting and tendon transfer.

* Factors influencing outcomes following peripheral nerve surgical procedures include length of time since injury, compressive pathology, type of nerve injured, and specific transfer technique.

* There are multiple techniques of distal nerve transfers. We provide outcomes-based guidance in deciding among the different treatment modalities available for patients who present with mononeuropathies.
Rethinking Fracturing at the Point of Attack
Authors: Rassenfoss Stephen
Published: April 2018

Paul Weddle describes himself as a “perforation geek.” The completion manager for Liberty Resources is among a small group that has an obsessive interest in all the details that can alter the performance of the openings blasted through casing, cement, and into rock during hydraulic fracturing.

The shaped charges that create circular openings with amazing force are a well-established technology that gets little notice so long as the guns go off as planned. But Weddle is among a few who see perforations as the point of attack for raising fracturing performance.

At the recent SPE Hydraulic Fracturing Technology Conference, Liberty reported completions in North Dakota that routinely stimulated more than 12 of 15 clusters, resulting in wells producing 1.7 to 2.5 times more than comparable wells (SPE 189880). By changing the way perforations were used, the operator was able to reduce the number of stages to 27 along a 9,500-ft lateral, which it estimates saved 15% on its finding and developing costs per barrel.

It stimulated those stages, which are about 350 ft long, with 15 clusters of perforations, with two perforations in each. This represents a significant break from the standard design of four or five clusters each with as many as six perforations. Since the tests reported in the paper, Weddle said Liberty has “gone all in on it.”

ConocoPhillips is working on designs with as many as 10 clusters per stage and two or three perforations per cluster, with all of them located at the top of casing, said Dave Cramer, a senior engineering fellow in completions for ConocoPhillips.

More clusters per stage allow operators to fracture longer wells without the cost of added stages, but Liberty and ConocoPhillips have not had a lot of company.

“I would say these ideas are not yet common to the industry, but at least a few operators and service companies are thinking about them,” said Robert Barree, president of Barree & Associates. The fracturing consultant said that “15 clusters are a lot. Most people are at the five to eight level … and some are at three.”

Grouping clusters with many perforations would seem to offer safety in numbers. The hard part about what is new is the old problem of directing a sufficiently strong stream of water into many small holes spread out along a long horizontal wellbore. Tight clusters of perforations can add stress that can interfere with fracture growth.

Liberty’s method depends on its ability to limit the fluid into each of the perforations to ensure that the high-pressure flow is distributed equally enough to stimulate most of the perforations. Liberty’s new method, called eXtreme Limited Entry (XLE), is based on work going back decades, including a paper in 1987 by Cramer (SPE 16189) on limited entry fracturing.

Technology Focus

On occasion, there is a tendency to equate new advances in automation and intelligent systems with an inevitable workforce reduction, to an extent that people can begin to resist their application. However, as we all know from our own oilfield experiences, intelligent systems require well-prepared and creative engineers to deliver a successful and economic outcome and a synergetic relationship enhances the business and opportunity set as a whole.

These technology advances offer a newer dimension to those options for qualified engineers to select, develop, and apply effective applications to ever-more-complex issues. As the resources that the industry develops become increasingly challenging, access to a broader range of options and new and developing approaches allows more-efficient and -effective recovery.

This month, I have selected a suite of papers that considers intelligent systems, all clearly demonstrating that these approaches are becoming increasingly mainstream in their selection and use. All the papers presented and suggested here demonstrate that the equipment, the techniques, or the systems alone cannot deliver the solutions. Instead, the systematic and innovative ways considered in their applications are responsible.

In time, the use of intelligent and automated systems will mature further into just another set of tools that the engineering community uses with increasing frequency to deliver the most-efficient development solutions. When that occurs, the industry preoccupation will have moved on to the next wave of innovations, technologies, and advancements, which no doubt will raise new and specific challenges.

Ultradeep-Field Study: Extreme-Underbalanced HP/HT Coiled-Tubing-Conveyed Perforating
Authors: Carpenter Chris
Published: April 2018

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 186948, “Extreme-Underbalanced High-Pressure/High-Temperature Coiled-Tubing-Conveyed Perforating: KN Ultradeep-Field Study,” by Miguel Rosato, Mohd Farris Bakar, and Fadzliana Azmi, Petronas, prepared for the 2017 SPE/IATMI Asia Pacific Oil and Gas Conference and Exhibition, Bali, Indonesia, 17–19 October. The paper has not been peer reviewed.

At an initial stage in a project to carry out the first high-pressure/high-temperature (HP/HT) field development offshore Malaysia, a locally conventional initial design considered the use of coiled-tubing-conveyed perforating (CTCP) to perforate a 7-in. liner and then to complete the well in open hole with overbalanced completion fluid. This solution posed several challenges that would have affected the safety of the completion process and the future integrity of the well architecture. A different approach, in which a fully cased hole well was completed in underbalance and then perforated once the completion was installed and tested, was used by the operator for the first time.

Introduction

The KN field is located west/northwest of Labuan offshore Sabah. The operator has been tasked to develop the KN ultradeep HP/HT reservoir (pressures exceeding 12,000 psi, temperature exceeding 300°F). The well production-casing envelope consisted of a single 10¾-×10⅛-×9⅞-in. production casing, while the reservoir section was drilled and then covered with a 7-in. production liner. This liner was cemented, secured at the top with a liner hanger, and secured at the bottom with a bridge plug.

Once these barriers were installed, the next operation in the well was to run a wellbore-cleanup assembly with a scraper, brushes, magnets, and an inflow-test packer. After wellbore cleanup, the drillpipe volume was displaced with inhibited fresh water, an initial inflow test was conducted, and, then, after good indication of well integrity, the well was displaced completely to inhibited fresh water. Immediately, an extended inflow test was conducted. At the time of the inflow test, the well was in an underbalanced condition of 6,000 psi at total depth. Fig. 1 shows the results.

Completion Design

The completion philosophy for the ultradeep well was a single completion string to be run in the closed well immediately after the wellbore-cleanup tools were out of the hole. After running the completion, the following operations were performed:

Setting the tubing hanger

Setting the production packer

Pressure testing the production packer from above and below

Nippling down the blowout preventer (BOP)

Nippling up the tree

Function and pressure testing the wellhead system

In the case of this well, these operations were conducted safely and within the allocated time and cost as per the approval for expenditure.
Analysis of consumers` innovation efficiency: changes of the consumption patterns in the Ukrainian society over the last 25 years
Authors: Sanko Hanna , Koldovskyi Artem
Published: April 2018

This paper reviews the transformation of Ukrainian consumption patterns since 1991 and the impact this change had on Ukrainian consumers. The authors research the market forces and the influence those forces had on the consumer behavior. Also, the authors conclude that these market forces resulted in transforming consumer behavior and consumption patterns. In this paper presents a conceptual analysis of the possible choices of market models and the implications of the Ukrainian society. Scientific findings demonstrate that users in Ukraine often play the main role in the creation of new conceptual products. But at the same time, there is a paucity of literature on this problem. The authors report a very high level of novelty by these consumers. The outcomes also reveal that innovating users can be distinguished from some non-innovating ones. Finally, innovation by users can be a significant basis of new product thoughts and ideas for consumer goods companies.

Vaccine Images on Twitter: Analysis of What Images are Shared (Preprint)
Authors: Chen Tao , Dredze Mark
Published: April 2018

BACKGROUND

Visual imagery plays a key role in health communication; however, there is little understanding of what aspects of vaccine-related images make them effective communication aids. Twitter, a popular venue for discussions related to vaccination, provides numerous images that are shared with tweets.

OBJECTIVE

The objectives of this study were to understand how images are used in vaccine-related tweets and provide guidance with respect to the characteristics of vaccine-related images that correlate with the higher likelihood of being retweeted.

METHODS

We collected more than one million vaccine image messages from Twitter and characterized various properties of these images using automated image analytics. We fit a logistic regression model to predict whether or not a vaccine image tweet was retweeted, thus identifying characteristics that correlate with a higher likelihood of being shared. For comparison, we built similar models for the sharing of vaccine news on Facebook and for general image tweets.

RESULTS

Most vaccine-related images are duplicates (125,916/237,478; 53.02%) or taken from other sources, not necessarily created by the author of the tweet. Almost half of the images contain embedded text, and many include images of people and syringes. The visual content is highly correlated with a tweet’s textual topics. Vaccine image tweets are twice as likely to be shared as nonimage tweets. The sentiment of an image and the objects shown in the image were the predictive factors in determining whether an image was retweeted.

CONCLUSIONS

We are the first to study vaccine images on Twitter. Our findings suggest future directions for the study and use of vaccine imagery and may inform communication strategies around vaccination. Furthermore, our study demonstrates an effective study methodology for image analysis.

Authors: Quan Peng , Wang Wenna , Chu Chengjing , Hou Lingfengz
Published: April 2018

We designed a short-term training course in mindfulness-based cognitive therapy (MBCT) for use with busy people with little time. We examined whether or not MBCT training would affect people's cognition. We assigned 44 participants with no prior experience with mindfulness techniques
randomly to either an MBCT group or a control group. These participants then completed the Trait Coping Style Questionnaire (TCSQ). After having undergone 7 days of training, we assessed participants again with the TCSQ and they also completed the Attention Network Test. Results showed that
orienting and executive control differed between the MBCT and control groups, but there was no difference between the 2 groups in alerting. The score for positive coping style was significantly enhanced in the group who had undergone MBCT training. Our findings suggest that MBCT can be an
effective approach to improve individuals' attentional subsystem and coping style in a short time.

Comparison of the effect of rest interval between sets and set – repetition configuration during bouts of eccentric exercise on muscle damage and inflammatory markers
Authors: Mohammadi Hossein , Afzalpour Mohammad Esmaiel , Abtahi Ivary Seyed Hossein
Published: April 2018

Background and Objective: Various studies have demonstrated that different rest Intervals has a significant effect on hormonal, metabolic and cardiovascular responses. This factors can lead to different muscle damage responses. Materials and Methods: 40 untrained subjects (25.4 ± 0.068 years, height 1.74 ± 0.97 cm and weight 30.8 ± 8.48 kg) in three sessions of eccentric resistance exercise with 24 hours rest between each session Participated in this study. Subjects were divided into 4 groups, A group:  5 sets of 10 repetition with the interset rest interval 1 minutes, B group: 10 sets of 5 repetition with the interset rest interval 3 minutes, C group: 10 sets of 5 repetition with the interset rest interval 3 minutes and D group: 5 sets of  10 repetition with the interset rest interval 3 minutes that performed 50 eccentric contractions with 85% of one repetition maximum. Each set includes 10 or 5 contractions that lower a person’ s weight in 3 s and at least 2 s to reach the next contraction without weights placed in full ﬂexion Around 1- or 3-min rest was given between each set. The experimental protocol was repeated for three consecutive days. The range of motion, the arm circumference, soreness and Alpha necrosis tumor factor were measured immediately before , immediately after and 24 hours after training. Results: Variance analysis with repeated measure demonstrated,  non-dominant arm circumference(P= 0.44), soreness (P= 0.76) and alpha necrosis tumor factor (P= 0.37) in different time points in 4 groups significantly increased and the range of motion (P= 0.44) decreased, but no significant difference in all dependent variables were found in 4 groups at different time points (P <0.05). Conclusion: Mechanisms of muscular damage caused by consecutive eccentric activities is independent of manipulating resistance exercise components (rest and the number of set-repetition) and possibly related to the muscular pressure entering to the muscles.
Active-grid turbulence effect on the topology and the flame location of a lean premixed combustion
Authors: Alhumairi Mohammed , Ertunç Özgür
Published: April 2018

Lean premixed combustion under the influence of active-grid turbulence was computationally investigated, and the results were compared with experimental data. The experiments were carried out to generate a premixed flame at a thermal load of 9 kW from a single jet flow combustor. Turbulent combustion models, such as the coherent flame model and turbulent flame speed closure model were implemented for the simulations performed under different turbulent flow conditions, which were specified by the Reynolds number based on Taylor?s microscale, the dissipation rate of turbulence, and turbulent kinetic energy. This study shows that the applied turbulent combustion models differently predict the flame topology and location. However, similar to the experiments, simulations with both models revealed that the flame moves toward the inlet when turbulence becomes strong at the inlet, that is, when Re? at the inlet increases. The results indicated that the flame topology and location in the coherent flame model were more sensitive to turbulence than those in the turbulent flame speed closure model. The flame location behavior on the jet flow combustor significantly changed with the increase of Re?.
Environmentally-based structural design criteria for buildings
Authors: Nenadovic Aleksandra , Tekic Zikica , Djordjevic Sasa
Published: April 2018

Activities related to buildings contribute to a large degree to environmental degradation. It is necessary to reduce the negative environmental impact and resource consumption throughout the life cycle of the building. The aim is to optimize building performances in accordance with the integrated design objectives. The building structure, along with other elements of architectural space, deter-mines the performances of the building. The building structure should be designed and evaluated as a sub-system of the building, whose behaviour is directed towards the aim of system-building ? ecological quality. This paper deals with the analysis of structural design in accordance with integrated design objectives, which are derived from quantitative and qualitative indicators of ecological quality of building, within the criteria of environmental protection throughout the life cycle of the building. The overall objective is to reduce harmful emissions to the air, water and soil, as well as to increase the efficiency of resource use, that is, to reduce the intensity of their use. Based on subject analysis, the environmentally-based criteria for the design and evaluation of building structures are derived, in the function of creating the environmentally acceptable building solutions. The present analysis points to the necessity of applying a complex and systemic approach to structural design, in function of achieving the ecological quality of buildings.
On the limits of the quasi-steady-state method to predict the energy performance of low-energy buildings
Authors: Ballarini Ilaria , Primo Elisa , Corrado Vincenzo
Published: April 2018

The recent European energy policies progressively introduced more restrictive energy performance requirements aimed at achieving the nearly zero-energy building target for all new buildings and major renovations. To check compliance with these requirements, the building energy performance can be evaluated through different calculation methods, as widely presented in literature. The present article is aimed at identifying in which boundary conditions (e. g. climate, use category, building size, thermal insulation level) a simplified steady-state calculation method can predict with sufficient accuracy the energy performance of low-energy buildings if compared with a dynamic simulation model. The analysis was performed on two building types, representative of the Italian residential typology, located in three different climatic zones and characterised by two insulation levels. The insulation levels fit the U-values of the notional reference building, established by the Italian legislation for checking compliance with energy performance requirements in two different steps; the first level is in force until 2020, while the second level is that of a reference nearly zero-energy building in force from 2021 onwards. The building energy performance, in terms of net energy needs for space heating and space cooling, was assessed by means of both the monthly calculation method of CEN standards and the detailed simulation model of EnergyPlus. Consistency options were applied to the models to guarantee that their outputs could be comparable. The quasi-steady-state method demonstrated to predict the cooling energy need quite well, but to lose in accuracy when the weight of the thermal transfer in the energy balance increases.

Authors: Balasubramanian Andi , Jayaraman Venkatesan , Sivan Suresh , Vairavan Mariappan
Published: April 2018

In this study, performance analysis of absorption refrigeration cycle has been carried out under variable power sources namely electrical and thermal energy sources. The triple fluid vapour absorption system was used in this work. The temperatures at each point in the cycle such as generator, absorber, evaporator and condenser have been measured. The coefficient of performance of the system was calculated and then compared. The results showed that when the cycle driven by electricity, the coefficient of performance varied from 0.28-1.6 along the test time and the generator temperature changed from 66?C to 106?C. When thermal energy used to generate power, the coefficient of performance varied between 0.16 and 0.6 under the generator temperature of 98?C and 150?C. It was observed that the waste heat energy from engine exhaust can be used efficiently and can replace the conventional power source to drive the absorption refrigeration unit.
Diesel production by fast pyrolysis of Miscanthus giganteus, well-to-pump analysis using the greet model
Authors: Peric Milica , Komatina Mirko , Antonijevic Dragi , Bugarski Branko , Dzeletovic Zeljko
Published: April 2018

In this paper ?well-to-pump? environmental analysis of pyrolytic diesel from Miscanthus gigantheus is performed. The average annual yield of Miscanthus from III-V year of cultivation on 1 ha of chernozem soil in Serbia (23.5 t) is considered as an input for the process. Two pyrolytic diesel pathways are considered: distributed pyrolytic pathway with external hydrogen production (from natural gas) and integrated pyrolytic pathway with internal hydrogen production (from pyrolytic oil). and are compared to a conventionally produced diesel pathway. The results of the analysis reveal that integrated-internal pyrolytic diesel pathway has lowest resources consumption and lowest pollutant emissions. Compared to conventionally produced diesel, integrated-internal pyrolysis pathway consumes 80% less of fossil fuels, and 92% more of renewables, has 90% lower global warming potential, 30% lower terrestrial acidification potential but 38% higher particulate matter formation potential. Compared to the distributed-external pathway, 88% less fossil fuels, and 36% less renewables are consumed in the integrated-internal pathway, global warming potential is 97% lower, terrestrial acidification is 20% lower, and particulate matter formation is 49% lower. Nevertheless, this pathway has high coal and hydroelectrical power consumption due to electricity production and high emissions of particulate matter, CO2, SOx, and N2O. Another drawback of this production pathway is the low yield of diesel obtained (38% lower than in distributed-external pathway). With this regard, it is still hard to designate production of diesel from fast pyrolysis of Miscanthus as a more environmentally friendly replacement of the conventional production diesel pathway.

Hyptis suaveolens (L.) Poit is one of the species Lamiaceae family (Labiatae), is an aromatic plant and can produce essential oils. Essential oils of these plants can be utilized as antimicrobials. The chemical components contained in the essential oils in the same plant may vary as they are influenced by several factors, including the growth stage. Essential oils can be obtained by hydrodestilation and their components are analyzed using gas chromatography-mass spectrometry (GC-MS). The essential oil components are then compared between those found in young leaves and adult leaves. The results of analysis and identification showed that in young leaves there are 50 components while in adult leaves there are only 37 components. The main components of young leaves were ?-caryophyllene (34.65%), germacrene-D (10.32%), ?-bergamotene (6.56%), ?-copaene (5.94%) and rimuene (6.46%), Are ?-caryophyllene (23.53%), germacrene-D (9.52%), ?-elemente (6.53%) and rimuene (13.19%). The components of ?-bergamotene and ?-copaene are not found in adult leaves.

The infinite series is an infinite sum of elements of a sequence of real numbers. A main thing related to the infinite series is to determine its convergence (convergent or divergent). Purpose this research were to analyze and determine a comparison and characteristics of each convergence test, such as: D'Alembert test, Raabe test, Gauss's test, Cauchy's Root Test, and Logarithm Test. A method used descriptive method by analyzing theories relevant to the problems discussed and based on literature study.The results showed that each convergence test had characteristics for its convergence test. The D'Alembert Ratio test is easier to use in a series that contains the formn! ,rn, and nn. Raabe test used if the ratio test obtained value limit comparison is, so the test does not give conclusion. Whereas logarithmic test is used in the infinite series that contains the logarithmic form. The Cauchy n-th root test, can be used to determine the absolute series convergence of the nth power

Authors: Jamrah Alfian
Published: April 2018

Pemberlakuan Undang-Undang Nomor 23 Tahun 2014 tentang Pemerintahan Daerah pada dasarnya adalah untuk menjadikan daerah otonom semakin mandiri dan dapat meningkatkan pelayanan pada masyarakat, sehingga terwujud kondisi daerah yang semakin baik dan semakin mampu mendukung pembiayaan penyelenggaraan pemerintahan, pembangunan, dan kemasyarakatan. Hal ini kelak tercermin dari peningkatan Pendapatan Asli Daerah (PAD) melalui inovasi penggalian potensi daerah dan pengembangan sumber daya Aparatur Sipil Negara (ASN). Sedangkan untuk meningkatkan pelayanan prima (service excellence) kepada masyarakat perlu pula ditemukan inovasi berbentuk praktek-praktek yang baik dari berbagai pengalaman daerah yang telah sukses serta memberdayakan potensi kearifan lokal. Peningkatan pelayanan masyarakat dimulai dari pembenahan pola fikir aparatur agar dapat memposisikan dirinya sebagai pelayan masyarakat, dan bukan sebagai pihak yang dilayani. Berbagai inovasi dalam pelayanan publik harus difikirkan, ditemukan dan diciptakan oleh pemerintah daerah provinsi, kabupaten dan kota untuk memberi kemudahan pada masyarakat. Inovasi-inovasi tersebut perlu dikompetisikan sehingga semua daerah berlomba untuk mendapatkan pelayanan prima yang mudah, murah, efisien, efektif dan memuaskan. Tulisan ini menyoroti dinamika pelayanan publik sebagai wujud mengisi otonomi daerah.

Perlunya investasi daerah dalam pengurangan risiko bencana (PRB) untuk ketangguhan merupakan tindakan prioritas ke-3 pada Kerangka Kerja Sendai (2015-2030). Variabel yang dikaji yaitu mengenai pelaksanaan kebijakan pembangunan sosial yang urgensinya untuk mencegah serta mengurangi risiko dari guncangan dan kerentanan sosial yang disebabkan oleh bencana alam, sehingga diharapkan kesiapsiagaan dan ketangguhan masyarakat dapat diwujudkan. Implementasi pendekatan PRB berbasis komunitas melalui program pembangunan sosial dipandang penting, mengingat belajar dari pengalaman terbukti bahwa kapabilitas pemerintah sangat terbatas dalam memfasilitasi penanggulangan bencana. Masyarakat hendaknya ditempatkan sebagai subjek yang aktif dengan berbagai kemampuannya untuk mengelola risiko.Penelitian ini bertujuan untuk mengkaji dan melihat tingkat kesiapan pembangunan sosial melalui program pemberdayaan masyarakat pesisir yang dilaksanakan oleh pemerintah. Metode yang digunakan adalah deskriptif dengan pendekatan kualitatif. Pengukuran levelisasi tingkat kesiapan program mengacu pada Peraturan Kepala BNPB No. 03/2012 tentang Panduan Penilaian Kapasitas Daerah dalam Penanggulangan Bencana. Hasilnya, kesiapan pembangunan sosial di wilayah pesisir Kulonprogo berada pada level 4, artinya daerah telah memperoleh beberapa pencapaian dari segi kebijakan dan implementasi program, namun diakui masih ada keterbatasan dalam hal komitmen terhadap keberlanjutan program.
