Effects of Buckled Tubing on Coiled Tubing Passibility
Authors: Qin Xing , Gao Deli 
Published: February 2017

Abstract
Many coiled tubing(CT) operations involve passage through the production tubing. However, due to the adverse wellbore trajectory or tubing geometries, especially in helically buckled tubing, the CT operations are still encountering various bottlenecks when it is pulled or lowered through the tubing. In this paper, a new concept "local model", which provides a sophisticated description of CT deflection in buckled tubing from local perspective, is proposed to help supplement the integral torque-drag model. Firstly, the CT can pass through the buckled tubing freely without any deformations. According to the constrained geometric relationship between the tubing and CT, the maximum CT length and maximum outside diameter can be calculated. Secondly, when the CT dimension parameters are beyond the scope of the above rigid dimension, the CT can pass through the tubing flexibly with deformations. So a beam-column model is established to analyze the CT deflection and bending behavior in snaky and helically buckled tubing. The results show that the buckled tubing configurations have significant effects on the CT passage dimension. Once the CT dimension parameters are out of the range of rigid dimension, it would contact the tubing at some points with large buckled tubing amplitude. Moreover, the contact forces and bending moments are influenced by the axial force and buckled tubing amplitude. This "local model" analysis results can be implemented in the torque-drag modeling to optimize the CT extended reach and axial force transfer.

Abstract
When coiled tubing is used for deliquification of multi-stage hydraulic fractured horizontal wells (MHFHW) in shale gas field, two serious problems arise. The gas-liquid from each fracture interferes with each other in horizontal wellhole, which causes serious energy waste. In addition, some fluids have to flow extra distance, as CT runs through some frac stages. this new design method is developed to solve these two issues. We propose a novel four-step design method for CT deliquification of MHFHW in shale gas field. Firstly, the interact of fluid from each fracture is analyzed by an inflow model, considering the geometry sizes of fracture and horizontal wellhole geometry. Then, the horizontal wellhole is divided into two sections, with CT and without CT, for flow simulation. After that, the multi-phase flow model of CT for MHFHW can be developed based on the results of step 1 and 2. Finally, combining the inflow model and the multi-phase flow model, CT size and depth can be optimized with the objective of minimizing bottomhole pressure and prolonging technological life. As this new design method considered interfered flows from hydraulic fractures and the influence by the CT in horizontal wellhole, it is convenient and meaningful to apply this new method to design the CT deliquification of MHFHW in shale gas field.
Novel Technique Applied to Lock Open SCSSV Installed in Monobore Subsea Completion in Deepwater GoM

Published: February 2017

Abstract
This paper highlights a unique technique used to overcome the specific challenge of locking open a failed-closed surface controlled sub-surface safety valve (SCSSV) in a monobore completion without a landing nipple profile above the SCSSV. The technical details of both the problem (inability to use conventional SCSSV lock open tools) and solution are discussed, with specific focus on the solution hardware and technique applied to deliver the objectives of the intervention.
Several techniques were considered and a matrix was developed to weigh the advantages and disadvantages of each. The technique selected utilized wireline to install a through-tubing expandable hanger assembly in the tubing pup joint above the SCSSV, with tubular extensions to "hold open" the flapper. The internal bore of the tubular extensions served as a conduit for the conveyance of the intervention tools required to be deployed deeper into the wellbore. This technique was successfully applied to two different wells to achieve the desired results.
The technique described in this paper for locking open a SCSSV is not limited to the monobore completion scenario with no available nipple profile. It is suitable for use on any SCSSV, regardless of the completion type or environment. This technique may prove to be a beneficial alternative when conventional lock open tools are not available or prove problematic in their application.

Published: February 2017

The article presents the results of the research in the realisation of ethics in social work activities. Social work is a complex and multifaceted profession in which practice is based on strong values. Social work values and ethical principles have been a particularly acute and debatable topic since ancient times. It has always been noticed that social work practical activities raise ethical issues and dilemmas. Ethical problems and their solutions are basic problems in the development of social work as a profession. Due to these reasons, the main goal of this article was set: to reveal how ethics are implemented by social workers in practice. In order to achieve the goal, the following objectives were set: 1. to explore the concept of ethics and values in social work context. 2. to analyse how the social worker's ethical standards are being implemented in various fields of activity. 3. to examine how ethics is realised in practice by the social workers of N District Municipality. In order to achieve the goal and tasks, the concept of ethics and values in social work was discussed as well as the analysis of social work ethics was implemented in various branches and spheres of activity. To reveal the topic, the research (survey) was carried out, which was attended by the N District Municipality social workers. Closed-ended questions were analysed by quantitative research methods and open-ended questions were processed by qualitative research methods. The results revealed that social workers of N District Municipality knew the ethical standards of their profession and implemented them in all the mentioned aspects of ethical codes. Social workers identified five main reasons which cause violations of ethical standards in their practice: apathy of colleagues, heavy workload, lack of offices, problematic clients and nervous tension at work.
Pars Plana Vitrectomy with Internal Limiting Membrane Peeling for Nontractional Diabetic Macular Edema
Authors: Ulrich Jan Niklas 
Published: February 2017

Background:
Diabetes mellitus remains the leading cause of blindness among working age Americans with diabetic macular edema being the most common cause for moderate and severe vision loss.

Objective:
To investigate the anatomical and visual benefits of pars plana vitrectomy with inner limiting membrane peeling in patients with nontractional diabetic macular edema as well as correlation of integrity of outer retinal layers on spectral domain optical coherence tomography to visual outcomes.

Methods:
We retrospectively reviewed the charts of 42 diabetic patients that underwent vitrectomy with internal limiting membrane peeling for nontractional diabetic macula edema. The integrity of outer retinal layers was evaluated and preoperative central macular thickness and visual acuity were compared with data at 1 month, 3 months and 6 months postoperatively. The student t-test was used to compare the groups.

Results:
31 eyes were included. While no differences were seen at 1 and 3 months, there was significant improvement of both central macular thickness and visual acuity at the 6 months follow up visit compared to preoperatively (357, 427 microns; p=0.03. 20/49, 20/82; p=0.03) . Patients with intact external limiting membrane and ellipsoid zone had better preoperative vision than patients with outer retinal layer irregularities (20/54, 20/100; p=0.03) and greater visual gains postoperatively (20/33, p<0.001 versus 20/81; p=non-significant).

Conclusion:
Pars plana vitrectomy with internal limiting membrane peeling can improve retinal anatomy and visual acuity in patients with nontractional diabetic macular edema. Spectral domain optical coherence tomography may help identify patients with potential for visual improvement.

Purpose:
To evaluate the macula with spectral domain type optic coherence tomography (OCT) in eyes with acute nonarteritic anterior ischemic optic neuropathy (NAION) at the presentation visit.

Methods:
Medical charts of the 133 patients who received the diagnosis of acute NAION between January 2008 and July 2014 at the Neuro-ophthalmology unit of Dokuz Eylul University were reviewed retrospectively. Sixtythree patients within 30 days of symptom onset with available baseline spectral domain type macular OCT were included in this study. Clinical and macular characteristics of the affected eye were assessed and compared to the fellow eyes.

Results:
Sixty-three eyes of 63 patients comprised the study group. Twenty one study eyes (33.3%) had normal posterior pole, 22 (34.9%) some evidence of subretinal fluid, 10 (15.8%) vitreomacular adhesion, five (7%) age-related macular degeneration related changes, four (6%) epiretinal membrane and one (1%) previous grid laser scars. On the other hand, 41 of 63 the fellow eyes (65%) had normal posterior pole, ten (15.8%), vitreomacular adhesion, seven (10.7%), age-related macular degeneration related changes, three (4%) epiretinal membrane and two (3%) other type of changes. OCT scan passing through the fovea exhibited 10 or more hyperreflective dots in 10 (15%) of the study eyes whereas two of the fellow eyes (3.2%) had 10 or more hyperreflective dots.

Conclusion:
Macular OCT can be a part of the routine neuroophthalmologic examination in patients with acute NAION not only to show the NAION related changes such as the subretinal fluid accumulation but also to identify the other coexistent macular abnormalities.
The Effects of Tangible Rewards versus Cash Rewards in Consecutive Sales Tournaments: A Field Experiment
Authors: Kelly Khim , Presslee Adam , Webb R. Alan 
Published: February 2017

ABSTRACT
We investigate the effects of tangible versus cash rewards in a repeated tournament setting. Firms frequently use tangible rewards to motivate employees, but minimal research has examined their effects relative to cash rewards. We conducted a field experiment at a rug wholesaler that held two consecutive sales tournaments for its retailers. The top three retailers in each tournament received either cash rewards or tangible rewards (gift cards) to be distributed to sales staff. We do not find significant effects of reward type in the first tournament. However, in the second tournament, retailers eligible for tangible rewards significantly outperformed those eligible for cash rewards, and this effect is driven by Tournament One losers. Our results are consistent with the theory that Tournament One losers competing for tangible rewards increased sales effort in the second tournament significantly more than their counterparts competing for cash rewards. Our results have practical and theoretical implications.
Using Drones in Internal and External Audits: An Exploratory Framework
Authors: Appelbaum Deniz , Nehmer Robert A. 
Published: February 2017

ABSTRACT:
Recently the FAA relaxed restrictions on the use of drones or Unmanned Aircraft Systems (UASs) for commercial purposes. Markets for commercial drone use are in the technology trigger phase of the Gartner Group's Hyper Cycle, with developments occurring rapidly in real estate, agriculture (farming), the film industry, insurance, and other areas. Examination and inspection applications of drones have been proposed in heavy industry and cell tower inspection. Previous research suggests an incremental structure for implementing technological innovations such as continuous auditing (CA). In this paper these proposals are expanded to include the additional requirements to add drone technologies. This structure is extended here by (1) defining the use of drones in audit environments, with emphasis on the continuous versus occasional use of drone technologies, (2) extending the technical adoption architecture to include the use of drones, and (3) considering the types of drone usages amenable to both internal and external audits. A specific architecture is proposed here to prototype inventory counts in large warehouses or open-air inventories and that satisfies the suggested requirements. Additionally, this proposal adds value to the current research by extending the discussion of technology adoption in the Alles, Kogan, and Vasarhelyi (2008) paper to include the use of drones in many different audit environments by enumerating the usage types of drones in audit settings and by considering the prototype of such a system.

Published: February 2017

The care and management of adolescents with type 1 diabetes presents numerous challenges that are inherent to the fears, attitudes, and perceptions of their illness. This qualitative study aimed to explore the “lived experience” of individuals with type 1 diabetes. In-depth interviews were conducted with 20 patients diagnosed with type 1 diabetes in their adolescent years to elicit their views, perceptions, and concerns regarding living with diabetes. All interviews were conducted and analyzed using the principles of grounded theory. Five categories defining the patients’ lived experience were elicited: Barriers, Develop Skills, Manage Emotion, Social World, and Health Care Professionals.
The problems experienced by adolescents with type 1 diabetes are multifactorial. Existentially, type 1 diabetes affects their daily activities and impinges on their academic achievement and personal aspirations. They have great difficulty coping with their health status and highlight a lack of empathy from health care professionals (HCPs). Their major fear is of hypoglycemia, resulting in their subsequent focus of preventing hypoglycemic episodes. Indeed, regardless of consequence, blood glucose levels are often deliberately kept above recommended levels, which serves to decrease the effectiveness of their health care management. This study shows that the quality of care provided for adolescent patients with type 1 diabetes is failing to meet their expectations and falls short of the essential standards commensurate with current health care policy. Improvements in long-term care management for these patients require changes in both patients’ and professionals’ understanding of the disease and of the ways it is managed.

Darma “pengabdian kepada masyarakat” oleh perguruan tinggi seringkali dikonotasi-kan sebagai suatu kegiatan pemberian bantuan dan pelayanan secara cumacuma kepada kelompok masyarakat yang lemah, tidak mampu secara ekonomis, dan berada dalam ko-disi keterbelakangan.Konotasi semacam itu adalah akibat dari kesalahan dalam menaf-sirkan istilah “pengabdian” terbatas sebagai suatu “kegiatan tanpa pamrih”. Padahal, kegiatan pemberian bantuan dan pelayanan tersebut hanya merupakan salah satu bentuk dari kegiatan pengabdian kepada masyarakat oleh perguruan tinggi, dan tidak selalu harus dilakukan secara cumacuma. Di samping itu, semua komponen organisasi perguruan tinggi dapat melaksanakan darma pengabdian kepada masyarakat ini, karena pelaksanaan darma tersebut tidak hanya menjadi tugas dan kewajiban dari lembaga fungsional seperti Lembaga Pengabdian Kepada Masyarakat yang telah dibentuk sec-ara khusus oleh perguruan tinggi. Dosen (baik secara pe-orangan maupun kelompok), Laboratorium, Jurusan, serta Pusat Penelitian, juga dapat melaksanakannya sesuai de-ngan bentuk kegiatan pengabdian yang relevan.
