ANALISIS PENGARUH PENYEMPITAN JALUR JALAN TERHADAP KARAKTERISTIK ARUS LALU LINTAS (STUDIKASUS : Jembatan Ayek Betung Jl. Kapten Sanap Kota Pagar Alam)

On several roads in the city of Pagar Alam the road narrowing occurred. In particular, on Bridges often cause problems such as congestion, queues, and delays, it is necessary to know the behavior of traffic flow characteristics such as Volume, Speed, and Density. The primary data survey on the Ayek Bridge section of Jalan Kapten Sanap, Pagar Alam City, was carried out for two Sundays and Mondays with the Manual Count method. Data analysis was based on the 1997 Indonesian Road Capacity Manual (MKJI) using Microsoft Excel software. As for the results of the study obtained the traffic volume for road type 4/2 D (before narrowing) road capacity of 5,643 pcu / hour perlajur, with a value of degree of saturation of 0,15 and service level Type A. Road type 2/2 UD (narrowing) road capacity of 2375 pcu / hour perlajur, with a value of Saturation 0.38 and Service Level Type A, 4/2 UD type road (After Refinement) road capacity of 5130 pcu / hour of service, with a value of 0.20 saturation and level Type A service. The biggest shock wave is obtained on Monday at 07.00-08.00 WIB which is -119.18 km / hour. Negative value is a backward forming shock wave, a backward shock wave occurs towards the arrival of the vehicle. The term 'retreat' means that with time, the shock wave will move backward (upstream or in the direction opposite to the traffic perger). The term 'formed' means that with time, congestion will increase upstream.&nbsp

Coping and Management Techniques Used by Chronic Low Back Pain Patients Receiving Treatment From Chiropractors.

OBJECTIVES:The purpose of this study was to describe coping strategies (eg, mechanisms, including self-treatment) that a person uses to reduce pain and its impact on functioning as reported by patients with chronic low back pain who were seen by doctors of chiropractic and how these coping strategies vary by patient characteristics. METHODS:Data were collected from a national sample of US chiropractic patients recruited from chiropractic practices in 6 states from major geographical regions of the United States using a multistage stratified sampling strategy. Reports of coping behaviors used to manage pain during the past 6 months were used to create counts across 6 domains: cognitive, self-care, environmental, medical care, social activities, and work. Exploratory analyses examined counts in domains and frequencies of individual items by levels of patient characteristics. RESULTS:A total of 1677 respondents with chronic low back pain reported using an average of 9 coping behaviors in the prior 6 months. Use of more types of behaviors were reported among those with more severe back pain, who rated their health as fair or poor and who had daily occurrences of pain. Exercise was more frequent among the healthy and those with less pain. Female respondents tended to report using more coping behaviors than men, and Hispanics more than non-Hispanics. CONCLUSION:Persons with chronic back pain were proactive in their coping strategies and frequently used self-care coping strategies like those provided by chiropractors in patient education. In alignment with patients' beliefs that their condition was chronic and lifelong, many patients attempted a wide range of coping strategies to relieve their pain

LNK (SH2B3): paradoxical effects in ovarian cancer.

LNK (SH2B3) is an adaptor protein studied extensively in normal and malignant hematopoietic cells. In these cells, it downregulates activated tyrosine kinases at the cell surface resulting in an antiproliferative effect. To date, no studies have examined activities of LNK in solid tumors. In this study, we found by in silico analysis and staining tissue arrays that the levels of LNK expression were elevated in high-grade ovarian cancer. To test the functional importance of this observation, LNK was either overexpressed or silenced in several ovarian cancer cell lines. Remarkably, overexpression of LNK rendered the cells resistant to death induced by either serum starvation or nutrient deprivation, and generated larger tumors using a murine xenograft model. In contrast, silencing of LNK decreased ovarian cancer cell growth in vitro and in vivo. Western blot studies indicated that overexpression of LNK upregulated and extended the transduction of the mitogenic signal, whereas silencing of LNK produced the opposite effects. Furthermore, forced expression of LNK reduced cell size, inhibited cell migration and markedly enhanced cell adhesion. Liquid chromatography-mass spectroscopy identified 14-3-3 as one of the LNK-binding partners. Our results suggest that in contrast to the findings in hematologic malignancies, the adaptor protein LNK acts as a positive signal transduction modulator in ovarian cancers

Increasing Eco-Efficiency Awareness for Ship Loading Process Using Virtual Reality and Gamification

The world is striving for a sustainable future as United Nations proposed the 17 Sustainable Development Goals to reduce the environmental impact and increase societal wellbeing by 2030. In this endeavor, eco-efficiency is considered as one of the key concept to facilitate the successful transition to the sustainable development with the focus to reduce the ecological impact of industry through efficiency improvements. The shipping industry is largely involved in this challenge with a target set by International Maritime Organization to cut emissions from individual ships by 40% from 2008 levels by 2030. The ship loading process is believed to have great impact to the overall eco-efficiency as it is not only a time consuming process but also determines the fuel consumption of the transportation. In this study, we aim to incorporate virtual reality (VR) technology and gamification theories to raise the eco-efficiency awareness in the shipping loading process. A VR application for ship loading process was developed using a real world case in the Baltic sea region. Eco-efficiency concept is introduced in different levels based on the gamification theories. Maritime professionals tested the VR application and provided their feedback. The results are positive that combining VR and gamification can be useful to train operators with eco-efficiency in ship loading operations. It also shows a huge potential to support the shipping industry in this transition towards a more sustainable future.

Loss-of-function of the ciliopathy protein Cc2d2a disorganizes the vesicle fusion machinery at the periciliary membrane and indirectly affects Rab8-trafficking in zebrafish photoreceptors

Ciliopathies are human disorders caused by dysfunction of primary cilia, ubiquitous organelles involved in transduction of environmental signals such as light sensation in photoreceptors. Concentration of signal detection proteins such as opsins in the ciliary membrane is achieved by RabGTPase-regulated polarized vesicle trafficking and by a selective barrier at the ciliary base, the transition zone (TZ). Dysfunction of the TZ protein CC2D2A causes Joubert/Meckel syndromes in humans and loss of ciliary protein localization in animal models, including opsins in retinal photoreceptors. The link between the TZ and upstream vesicle trafficking has been little explored to date. Moreover, the role of the small GTPase Rab8 in opsin-carrier vesicle (OCV) trafficking has been recently questioned in a mouse model. Using correlative light and electron microscopy and live imaging in zebrafish photoreceptors, we provide the first live characterization of Rab8-mediated trafficking in photoreceptors in vivo. Our results support a possibly redundant role for both Rab8a/b paralogs in OCV trafficking, based on co-localization of Rab8 and opsins in vesicular structures, and joint movement of Rab8-tagged particles with opsin. We further investigate the role of the TZ protein Cc2d2a in Rab8-mediated trafficking using cc2d2a zebrafish mutants and identify a requirement for Cc2d2a in the latest step of OCV trafficking, namely vesicle fusion. Progressive accumulation of opsin-containing vesicles in the apical portion of photoreceptors lacking Cc2d2a is caused by disorganization of the vesicle fusion machinery at the periciliary membrane with mislocalization and loss of the t-SNAREs SNAP25 and Syntaxin3 and of the exocyst component Exoc4. We further observe secondary defects on upstream Rab8-trafficking with cytoplasmic accumulation of Rab8. Taken together, our results support participation of Rab8 in OCV trafficking and identify a novel role for the TZ protein Cc2d2a in fusion of incoming ciliary-directed vesicles, through organization of the vesicle fusion machinery at the periciliary membrane
