Heat Transfer Correlations on Combustion Chamber Surface of Diesel Engine - Experimental Work
Authors: KUMAR Shiva , KUMAR Ajeet , SHARAMA Abhilash Rai , KUMAR Amit 
Published: September 2018

Design
and control of recently developing engines have much important towards better
fuel economy and reduction in exhaust emissions from an engine. Since the
ignition takes place due to high compression (or) self ignition of temperature
in case of diesel engines, the temperature distribution and heat flux on the
combustion chamber surface are an important phenomenon.

While modifying the profile of combustion chamber of diesel engine, it
is important to relocate the hot spot regions on the combustion chamber surface
which supports combustion initiation. With these hot spot regions on combustion
chamber surface regulates/controls ignition delay period which results in
controlled detonation. In diesel engines, controlled detonation which in turn
improves engine performance and reduced emissions. Therefore, to include the hot spot regions at proper
locations, it is required to measure the temperature values at different locations/coordinates
with the help of thermocouples on the cylinder head surface exposed to
combustion chamber. Also the adiabatic flame temperature, the engine
performance parameters, heat balance date, convection and radiation heat
transfer related terms were calculated and analyzed
STUDI KASUS PENERAPAN VENDOR MANAGED INVENTORY PADA SISTEM RANTAI PASOK
Authors: Martono (Sekolah Tinggi Manajemen PPM) Ricky 
Published: September 2018

<p><em>K</em><em>onsep Vendor Managed Inventory (VMI) merupakan salah satu pendekatan dalam mengelola inventori yang efisien antara pemasok dan konsumen di dalam sebuah sistem rantai pasok. Dengan VMI, pemasok menempatkan inventorinya di konsumen, namun kepemilikan inventori berpindah kepada konsumen ketika inventori digunakan. Keuntungan menerapkan VMI diantaranya adalah mengurangi proses pemesanan inventori dan mengurangi pemakaian ruang penyimpanan inventori di pemasok. Untuk mencapai ini dibutuhkan koordinasi, komunikasi, dan kehandalan sistem produksi dan pemesanan inventori yang tangguh untuk menerapkan VMI. Dalam kondisi dimana pemasok merupakan anak perusahaan dari konsumen, maka koordinasi tidak selalu menempatkan pemasok dan konsumen pada posisi setara. Terlebih ketika infrastruktur pemasok tidak sekuat konsumen. Penelitian ini dikhususkan pada studi kasus di sebuah perusahaan farmasi dan pemasoknya dimana pemasok merupakan anak perusahaannya. Informasi diperoleh melalui wawancara kepada pihak terkait di pemasok dan konsumen. Hasil pengamatan menunjukkan kelebihan dan hambatan dalam menerapkan VMI, sehingga dibutuhkan komitmen jangka panjang untuk mencapai keberhasilan yang lebih baik.</em></p>

Published: September 2018

Objective: To compare the sensitivity, specificity and accuracy of the one-step nucleic acid amplification (OSNA) assay and frozen sections.Material and Method: One hundred and twenty patients with early breast cancer and no clinical nodal involvement underwent intraoperative sentinel lymph nodes (SLNs) evaluation and undertaken axillary lymph nodes dissection (ALND) at the Department of Surgery, Songklanagarind Hospital from March 1st, 2011-November 30th, 2014.Results: A total of 213 SLNs were evaluated (mean 1.84 nodes). The accuracy of the OSNA assay compared to histological evaluation was 95.7%. The OSNA assay performance was: sensitivity 100% (25/25); specificity 95.2% (179/188); positive predictive value (PPV) 73.5% (25/34) and negative predictive value (NPV) 100% (179/179). Turnaround time was an average 39.6 minutes. The accuracy of frozen sections compared to histological evaluation was 99.1%. The frozen sections performance was: sensitivity 92% (23/25); specificity 100% (188/188); PPV 100% (23/23) and NPV 98.9% (188/190). After discordant analysis, the PPV of the OSNA assay on nodes with macrometastases (++) was 100% (25/25), and the result on nodes with micrometastases (+) was 75% (3/4). The accuracy of OSNA after review was thus 99.5%.Conclusion: The OSNA assay is accurate and rapid for SLN evaluation and it can replace the frozen section in general practice.

Published: September 2018

Objective: To determine the antimalarial activity of ethanol crude extracts from 20 Thai herbs against Plasmodiumfalciparum (P. falciparum) chloroquine-resistant strain TM267. Molecular docking of the active compounds from the selected Thaiherbs were analyzed with Plasmodium falciparum dihydrofolate reductase (PfDHFR).Material and Method: An in vitro study of antimalarial activity against P. falciparum TM267 was done using a parasitelactate dehydrogenese assay, and the cytotoxic effects of extracts were tested against Vero cells using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. The 50% inhibitory concentration (IC50) and 50%cytotoxicity concentration were calculated from the dose-response curves. Molecular docking and post-dockingwere analyzed with the x-ray crystal structure of PfDHFR-thymidylate synthase complexed with pyrimethamine,nicotinamide adenine dinucleotide phosphate and deoxyuridylate.Results: Of these, the Plumbago indica L. root extract showed high antimalarial activity, with an IC50 value of 3.7μg/ml and less cytotoxicity when tested against Vero cells, followed by the Citrus hystrix DC. fruit extract, Vitex trifoliaLinn. root extract, Ocimum sanctum L. leave extract, of Allium sativum L. bulb extract and Salacia chinensis L. stem extract,respectively. All 7 active compounds reported from these herbal extracts had high docking scores against PfDHFR.The Citrusoside C from Citrus hystrix DC. had the highest docking score.Conclusion: It could be purposed that there were active compounds in Plumbago indica L., Vitex trifolia Linn. and Citrus hystrix DC. which are potential inhibitors against malaria that could bind to the active site of PfDHFR. However, the active Citrusosides from Citrus hystrix DC. should be further investigated for their effectiveness against malaria.

OBJECTIVEAmong clinical and morphological criteria, hemodynamics is the main predictor of aneurysm growth and rupture. This study aimed to identify which hemodynamic parameter in the parent artery could independently predict the rupture of anterior communicating artery (ACoA) aneurysms by using multivariate logistic regression and two-piecewise linear regression models. An additional objective was to look for a more simplified and convenient alternative to the widely used computational fluid dynamics (CFD) techniques to detect wall shear stress (WSS) as a screening tool for predicting the risk of aneurysm rupture during the follow-up of patients who did not undergo embolization or surgery.METHODSOne hundred sixty-two patients harboring ACoA aneurysms (130 ruptured and 32 unruptured) confirmed by 3D digital subtraction angiography at three centers were selected for this study. Morphological and hemodynamic parameters were evaluated for significance with respect to aneurysm rupture. Local hemodynamic parameters were obtained by MR angiography and transcranial color-coded duplex sonography to calculate WSS magnitude. Multivariate logistic regression and a two-piecewise linear regression analysis were performed to identify which hemodynamic parameter independently characterizes the rupture status of ACoA aneurysms.RESULTSUnivariate analysis showed that WSS (p < 0.001), circumferential wall tension (p = 0.005), age (p < 0.001), the angle between the A1 and A2 segments of the anterior cerebral artery (p < 0.001), size ratio (p = 0.023), aneurysm angle (p < 0.001), irregular shape (p = 0.005), and hypertension (grade II) (p = 0.006) were significant parameters. Multivariate analyses showed significant association between WSS in the parent artery and ACoA aneurysm rupture (p = 0.0001). WSS magnitude, evaluated by a two-piecewise linear regression model, was significantly correlated with the rupture of the ACoA aneurysm when the magnitude was higher than 12.3 dyne/cm2 (HR 7.2, 95% CI 1.5–33.6, p = 0.013).CONCLUSIONSWSS in the parent artery may be one of the reliable hemodynamic parameters characterizing the rupture status of ACoA aneurysms when the WSS magnitude is higher than 12.3 dyne/cm2. Analysis showed that with each additional unit of WSS (even with a 1-unit increase of WSS), there was a 6.2-fold increase in the risk of rupture for ACoA aneurysms.

Authors: Jorge Ahmed , White Michael D. , Agarwal Nitin 
Published: September 2018

OBJECTIVEIndividuals with a spinal cord injury (SCI) in socioeconomically disadvantaged settings (e.g., rural or low income) have different outcomes than their counterparts; however, a contemporary literature review identifying and measuring these outcomes has not been published. Here, the authors’ aim was to perform a systematic review and identify these parameters in the hope of providing tangible targets for future clinical research efforts.METHODSA systematic review was performed to find English-language articles published from 2007 to 2017 in the PubMed/MEDLINE, EMBASE, and SCOPUS databases. Studies evaluating any outcomes related to patients with an SCI and in a low-resource setting were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a flowchart was created. Of the 403 articles found, 31 underwent complete review and 26 were eligible for study inclusion. According to the current study criteria, any case studies, studies in less developed countries, studies including and not separating other types of neurological disorders, studies not assessing the effects of a low-resource setting on outcomes in patients with SCI, and studies evaluating the causes of SCI in a low-resource setting were excluded.RESULTSIn SCI patients, a lower income was a predictor of death (OR 2.1, 95% CI 1.7–2.6, p = 0.0002). Moreover, secondary outcomes such as pain intensities (OR 3.32, 95% CI 2.21–4.49, p < 0.001), emergency room visits (11% more likely, p = 0.006), and pressure ulcer formation (OR 2.1, 95% CI 1.5–3.0, p < 0.001) were significantly higher in the lower income brackets. Rurality was also a factor and was significantly associated with increased emergency room visits (OR 1.5, 95% CI 1.1–2.1, p = 0.01) and lower outpatient service utilization (incidence rate ratio [IRR] 0.57, 95% CI 0.35–0.93, p < 0.05).CONCLUSIONSThe authors showed that individuals in a low-resource setting who have suffered an SCI have significantly different outcomes than their counterparts. These specific outcomes are promising targets for future research efforts that focus on improving health conditions among this population.

Authors: Ryu Samuel , Rock Jack , Rosenblum Mark , Kim Jae Ho 
Published: September 2018

Object. Single-dose radiosurgery for solitary spinal metastases can achieve rapid and durable pain control. This study was conducted to determine the patterns of failure after spinal radiosurgery.
Methods. Forty-nine patients with 61 solitary spinal metastases underwent radiosurgery between May 2001 and May 2003. Single-dose radiosurgery (10–16 Gy) was delivered only to the involved spinal segments. The authors undertook a retrospective review of clinical notes, including patient questionnaires and radiological studies (computerized tomography or magnetic resonance imaging), to analyze patterns of failure following radiosurgery with regard to the pain and tumor control.
Complete and partial pain relief was achieved in 85% of the lesions treated. Relapse of pain at the treated site was noted in 7%. Radiologically, lesions progressively metastasized to the immediately adjacent spines in 5%. These patients also had progressive primary and/or other systemic metastatic diseases.
Conclusions. Spine-related pain control/reduction was excellent. Tumor recurrence at the treated segment and progression to the immediately adjacent region were rare. The results support the use of spinal radiosurgery as an effective treatment option for solitary spinal metastasis.

Object. Spinal radiosurgery was implemented to improve quality of life (QOL) in patients with malignancies. It may also be applicable to the treatment of benign lesions.
Methods. Between July 2002 and January 2004, 14 patients harboring 22 lesions were treated; 13 received single-dose stereotactic radiosurgery. Six were women. The mean age was 60.2 years (range 48–82 years). There were 11 metastases, two neurofibromas, and one meningioma. Six lesions were cervical, 10 thoracic, and six lumbar. Ten patients suffered pain, three paresthesias, two weakness, and three were asymptomatic. Seven patients underwent spinal surgery, with four receiving instrumentation. Twelve patients underwent conventional irradiation before stereotactic radiosurgery/stereotactic radiotherapy. A mean dose of 12 ± 2.7 Gy (range 8–21 Gy) was prescribed to the 91% isodose line (range 85–97%). The mean tumor volume was 25 ± 27.1 ml (range 0.75–91.8 ml). Treatment was planned using intensity-modulated radiosurgery (IMRS) fields in 15 cases, dynamic arcs in five, and conformal beams in two. The mean follow-up period was 6.1 ± 3.9 months (range 1–16 months).
Three patients became pain free and four experienced considerable relief. Weakness improved in the two patients with this preoperative symptom and the asymptomatic patients remained so. Four lesions decreased in size, five remained stable, seven progressed, and six were not followed up (two patients died before follow up). Four patients in all died, three of systemic disease and one of thoracic lesion progression. No complications due to shaped beam and IMRS/intensity-modulated radiotherapy (IMRT) techniques were observed.
Conclusions. Shaped beam and IMRS/IMRT involving the Novalis system may delay neurological deterioration, improving QOL. The lack of complication suggests that higher doses can be delivered to improve the control rate in patients with metastases.
