CALCULATION OF CHARACTERISTICS OF STIFFNESS AND ELASTICITY OF RAIL THREADS WHEN TORSION UNDER COMBINED ACTION OF VERTICAL AND HORIZONTAL FORCES
Authors: Danilenko E. I. 
Published: December 2016

Purpose. Reference data in technical literature about such characteristics as stiffness and elasticity of rail threads at torsion are rather contradictory. This is due to the absence of correct analytical solution of this task and because of complexity of experimental studies of this problem under combined action of vertical and horizontal lateral forces. The article presents the new method of solving the task of calculation the real values of stiffness and elasticity modules of rail thread when torsion under combined action of vertical and horizontal lateral forces. Methodology. The complex method of solving the problem was used in the paper. It includes the theoretical part and the results of the experiment. Using the experiment the characteristics of horizontal lateral stiffness of the rail threads of the head and bottom at different constructions of the modern rail fastenings was measured. The second task of determination of the real values of elasticity and stiffness modulus of the rail thread when torsion was solved by the theoretical methods. Findings. New values of stiffness characteristics and elasticity module of rail thread when torsion for the modern rail constrictions Р65, UIC60, Р50 and the rail fastenings of the types КПП, КБ, ДО, under combined action of vertical and horizontal forces and torsion were obtained. Originality. For the first time in domestic research it was carried out the experimental and theoretical solution of the task for determination of the real values of the stiffness and elasticity modulus of rail thread when torsion under combined action of vertical and horizontal forces of the wheel loadings. The solution is represented in the functional dependence on the correlation of vertical and horizontal forces ; acting together. The solution is carried out for the modern designs of the rails of domestic standard P65, P50, P43 and international standard UIC60. Practical value. The obtained results make it possible to carry out calculations of the real acting strains and deformations in the rails of different types under the joint action of vertical and horizontal forces for railway track on concrete and wooden sleepers with different designs of rigid and elastic rail fastenings КБ, КПП, Д0 with higher accuracy as compared to the current calculation methodology.
Percepción de la comunidad del archipiélago de Bocas del Toro, Panamá, sobre el impacto de la industria turística
Authors: Camargo Velandia Mercedes 
Published: December 2016

Desarrollar políticas públicas que impulsen el turismo y respondan al cambio climático exige el análisis de múltiples variables sociales, económicas y ambientales. En el contexto de la gestión de las zonas aisladas físicamente, como los archipiélagos, dicho análisis depende de conocer las características ambientales y las necesidades socioeconómicas de las comunidades locales que permitan reconocer las percepciones de los individuos. Este trabajo se centra en este aspecto social y se interesa en conocer la percepción de la comunidad sobre los impactos socioeconómicos y ambientales que ha experimentado en los últimos años como consecuencia del turismo que se está desarrollando en el archipiélago de Bocas del Toro. En la investigación se realizaron 200 entrevistas durante 2013 en cuatro islas del archipiélago de Bocas que desarrollan actividades turísticas. Los resultados del estudio permiten caracterizar a la comunidad y conocer su percepción teniendo en cuenta que desarrollan actividades estrechamente ligadas al turismo y que este se desarrolla en un escenario altamente desregularizado, donde hay una débil capacidad de control y seguimiento por parte del Estado, lo que ha impulsado un proceso desordenado de construcción y ocupación del territorio.Se concluye que la percepción de la comunidad local se encuentra dividida marginalmente a favor del desarrollo de la industria turística por una mayor conciencia de los costos y beneficios que el turismo ha traído. Sin embargo, las voces de euforia inicial con la venta de casas y terrenos a extranjeros realizada en los años noventa han cedido espacio a una visión más crítica y más social. Los aspectos más positivos del desarrollo de la industria del turismo en este lugar son su aporte en el dinamismo de la economía local –en comparación con la situación de 1983– y la mejora en la infraestructura, que han resultado atractivos para que personas de otros lugares lleguen al archipiélago en busca de oportunidades de trabajo. Los encuestados no notan que haya un deterioro importante de los ecosistemas y reconocen que ellos no tienen una cultura ambiental para proteger las playas. La comunidad local utiliza y valora 14 servicios ecosistémicos, especialmente los de provisión, soporte y cultural, que forman parte de sus estrategias y medios de vida. Los operadores turísticos valoran seis servicios, específicamente de provisión, regulación y cultura, que están estrechamente ligados al desarrollo de la actividad turística, el acceso y la oportunidad de integrarse a la labor turística. También se descubre que las mujeres, en general, reciben menos ingresos que los hombres.

FIQIH NUSANTARA (Kontekstualisasi Hukum Islam dalam Pandangan T.M. Hasbi al-Shiddiqi)
Authors: Maimun Maimun 
Published: December 2016

Perbedaan ruang dan waktu berakibat pada perubahan dan kemajuan peradaban telah membentuk perbedaan pendekatan hukum Islam yang lebih didasarkan pada kultur dan tradisi masya­rakat. Dalam konteks ini TM. Hasbi al-Shiddiqi muncul sebagai ulama pertama yang berkonsentrasi pada pembentukan fiqih Indonesia. Ia merupakan tokoh reformis yang banyak dipengaruhi oleh al-Kalali dan Ahmad Soorkati. Dalam merealisasikan pandangannya, Hasbi menawarkan formulasi konsep ijtihad yang berorientasi lokal keindonesiaan, yaitu; Ijtihad dengan mengklasifikasikan hukum produk ulama mazhab masa lalu kemudian dipilih produk hukum yang masih cocok untuk diterapkan dalam masyarakat Indonesia; Ijtihad dengan mengklasifikasikan hukum-hukum yang semata-mata didasar­kan pada adat dan kebiasaan serta suasana masyarakat dimana hukum tersebut berkembang; dan Ijtihad dengan mencari hukum-hukum terhadap masalah kontemporer yang timbul sebagai akibat dari kemajuan ilmu pengetahuan. Sedangkan tawaran konsep metodologis­nya meliputi pemahaman tentang fiqih dan syari’ah, analisis kese­jarahan, pendekatan sosio kultural, dan studi perbandingan.

Published: December 2016

Background:Though often perceived as a “silver bullet” treatment for bipolar disorder (BD), lithium has seldom reported to lose its efficacy over the time.Objective:The aim of the present study was to assess cases of refractoriness toward restarted lithium in BD patients who failed to preserve maintenance.Method:Treatment trajectories associated with re-instituted lithium following loss of achieved lithium-based maintenance in BD were retrospectively reviewed for 37 BD-I patients (median age 52 years; F:M=17:20 or 46% of the total) over an 8.1-month period on average.Results:In our sample only 4 cases (roughly 11% of the total, of whom F:M=2:2) developed refractoriness towards lithium after its discontinuation. Thirty-three controls (F:M=15:18) maintained lithium response at the time of re-institution. No statistically significant difference between cases and controls was observed with respect to a number of demographic and clinical features but for time spent before first trial ever with lithium in life (8.5vs.3 years; U=24.5, Z=-2.048, p=.041) and length of lithium discontinuation until new therapeutic attempt (5.5vs.2 years; U=8, Z=-2.927, p=.003) between casesvs.controls respectively. Tapering off of lithium was significantly faster among casesvs.controls (1vs.7 days; U=22, Z=-2.187), though both subgroups had worrisome high rates of poor adherence overall.Conclusion:Although intrinsic limitations of the present preliminary assessment hamper the validity and generalizability of overall results, stating the clinical relevance of the topic further prospective research is warranted. The eventual occurrence of lithium refractoriness may indeed be associated with peculiar course trajectories and therapeutic outcomes ultimately urging the prescribing clinicians to put efforts in preserving maintenance of BD in the absence of any conclusive research insight on the matter.

Published: December 2016

Background:The optimal antiplatelet therapy (APT) treatment strategy after Coronary Artery Stenting (CAS) in non-cardiac surgery, such as total knee arthroplasty (TKA) or urgent TKA-related surgery remains unknown.Methods:We built a decision tree model to examine the mortality outcomes of two alternative strategies for APT after CAS use in the perioperative period namely, continuous use and discontinuation.Results:If surgery was performed in the first month after CAS placement, discontinuing APT led to an estimated 30-day post TKA mortality of 10.5%, compared to 1.0% in a strategy with continuous APT use. Mortality with both strategies decreased with longer intervals.Conclusion:Our model demonstrated that APT discontinuation in patients undergoing TKA or urgent TKA related surgery after CAS placement might lead to greater 30-day mortality up to one year.
Double-barrel Y-configuration Stenting for Flow Diversion of a Giant Recurrent Basilar Apex Aneurysm with the Pipeline Flex Embolization Device
Authors: Ding Dale , Starke Robert M. , McGuinness Ben , Brew Stefan 
Published: December 2016

ABSTRACTGiant basilar apex aneurysms are extremely challenging to successfully manage. The Pipeline Flex embolization device (PFED) is a new generation flow-diverting stent with a modified delivery system which allows resheathing of the stent after partial deployment. We describe a case of double-barrel Y-configuration stenting of a giant, recurrent basilar apex aneurysm using the PFED. A 73-year-old male was previously treated for an unruptured 11-mm basilar apex aneurysm with stent-assisted coiling using a Neuroform stent. The aneurysm was retreated twice with repeat coiling. After the third recurrence and persistent aneurysm growth into a giant, symptomatic lesion, we decided to proceed with flow diversion. We performed Y-stenting of the basilar bifurcation using three PFEDs, and was recoiled the aneurysm sac. Due to the low porosity of the flow diverters, a side-by-side double-barrel configuration was necessary in the basilar artery. Without the PFED’s resheathable capability, it would not have been possible to perform Y-stenting with flow diverters.
Association of Cognitive and Noncognitive Symptoms of Delirium: A Study from Consultation-liaison Psychiatry Set-up
Authors: Grover Sandeep , Mehra Aseem , Chakrabarti Subho , Avasthi Ajit 
Published: December 2016

ABSTRACT
Aims: This study aims to evaluate the cognitive functions of patients with delirium using Hindi Mental Status Examination (HMSE), to study the correlation of cognitive functions assessed by HMSE with noncognitive symptoms as assessed using Delirium Rating Scale-Revised 1998 (DRS-R-98) and to study the association of cognitive functions assessed using HMSE and DRS-R98. Methods: A total of 76 consecutive patients fulfilling the diagnosis of delirium were evaluated on DRS-R-98, HMSE, and Short Informant Questionnaire on Cognitive Decline in the Elderly (retrospective IQCODE). Results: The mean DRS-R-98 score 33.9 (standard deviation [SD] - 7.2) and the mean DRS-R-98 severity score was 25.9 (SD - 7.2). The mean score on HMSE was 19.3 (7.98). There were significant correlations of all the domains of HMSE with DRS-R-98 total score, DRS-R-98 severity score, DRS-R-98 cognitive subscale score, DRS-R-98 noncognitive domain subscale score, and DRS severity score without attention score. When the association of each item of DRS-R-98 and HMSE was evaluated, except for the items of delusions, lability of affect and motor retardation, there were significant negative association between all the items of DRS-R-98 and HMSE, indicating that higher severity of cognitive symptoms as assessed on HMSE is associated with higher severity of all the cognitive symptoms and most of the noncognitive symptoms as assessed by DRS-R-98. Conclusion: The present study suggests that attention deficits in patients with delirium influence the severity of cognitive and noncognitive symptoms of delirium. Further, the present study suggests an increase in the severity of cognitive symptoms in other domains is also associated with an increase in the severity of noncognitive symptoms of delirium.

Published: December 2016

ABSTRACT
Background: Benin republic is a very low-income French-speaking country in West Africa The development of Neurosurgery in the Republic of Benin took off with the arrival of the first Beninese neurosurgeons in the year 2003. Aims: This study aims to evaluate patients’ attendance in a public neurosurgical center, and appreciate populations’ affordability to a new specialty. Settings and Design: In the year 2004, the Benin Armed Forces established the first Department of Neurosurgery in the Nation’s Military Teaching Hospital. From the public authorities, that was a proof of motivation to develop this specialty in the Benin Republic. Materials and Methods: A retrospective cross-sectional survey (September 2003 to December 2009) of the total neurosurgical patient population managed in a public pioneer hospital in a developing country. Statistical Analysis Used: Data were captured and analyzed with the SPSS software (SPSS Inc., Chicago, IL, USA) and presented in descriptive statistics such as frequencies and proportions. Results: 2908 new patients, civilians, and militaries were registered. The surgical treatment was offered adult (86%) as well as pediatric (14%) patients. Spinal degenerative diseases (52.1%) were the most common pathology; neurotraumatology emergency cases (8.4%) appeared low in representation. Three-quarters of patients experienced financial difficulties to procure the required radiologic investigations and although 609 (20.94%) benefited from surgery, most patients could not pay for the surgical operations as well as the perioperative care. Conclusions: In spite of the great constraints of this country’s privately-funded health-care delivery system on the affordability of neurosurgical treatment for the average Beninese, this study demonstrates a globally increasing attendance of the department.

Published: December 2016

ABSTRACT
Introduction: With the advancement of therapeutics, newer antiepileptic drugs (AEDs) like Levetiracetam (LEV), with good therapeutic efficacy and tolerability are available. But unfortunately, therapeutic drug monitoring is not routinely done in India for these drugs. Objectives: The objective of this study is to determine the range of serum levels of LEV in patients at stabilized doses and correlate them with their clinical course. Materials and Methods: Patients with epilepsy and started on LEV were enrolled from the Neurology Department after the Ethics Committee approval. Serum levels of LEV were estimated using high-performance liquid chromatography and correlated with patient demographics, dosage, dosage forms, concomitant AEDs, compliance of the patient, therapeutic effect, adverse drug reactions (ADRs), and suspected toxicity. Results: Serum levels of LEV ranged from 0.4 to 102.2 μg/ml at different time points and demonstrated a negligible positive correlation with age of the patients (r = 0.12) but negligible negative correlation with bodyweight (r = −0.19). No conclusive relationship could be established for dose, gender, dosage forms, clinical efficacy (seizure frequency), ADRs, and toxicity. Compliance was verified in all the patients. Levels were found to reduce with the use of concomitant enzyme inducer drugs (56.78%) whereas increase with valproic acid (7.8%). Conclusion: These findings emphasize the need for monitoring the serum levels of newer AEDs like LEV considering the various parameters studied here, so as to maintain the therapeutic efficacy by preventing under or over dosage and to generate a broader database of serum levels of LEV in the Indian population to help appropriate prescribing with more confidence.
