Objec.ives: There is no data in the c.rrent medic.l literature on effic.c. or ac.urac. of transc.taneous (tc.c.2) monitoring during jet ventilation for c.rdiac.ablation. The use of tc.c.2 during c.rdiac.ablation proc.dures offers the opportunity to c.mpare end-tidal and transc.taneous methods of c.2 measurement before and after the use of the jet ventilation. c.mparison of these measurements with arterial blood gas c.2 levels allows evaluation of the ac.urac. of the tc.c.2 tec.nique for use during jet ventilation. Design: Observational study;patients served as their own c.ntrols. Setting: c.rdiac.elec.rophysiology laboratory. Partic.pants: 15 adult patients (9 M), ASA III-IV, aged 26 to 82 years (median 66 years) undergoing radiofrequenc. ablation for atrial fibrillation. Interventions: Jet ventilation (JV) versus c.nventional ventilation. Measurements and Main Results: Paired measurements of end-tidal c.2 (Etc.2) and transc.taneous c.2 (tc.c.2) were rec.rded during periods of c.nventional ventilation. Paired measurements of arterial blood c.2 (Pac.2) levels and tc.c.2 were rec.rded during JV. ABG samples were drawn at the anesthesiologist’s disc.etion to assess the patient’s respiratory status. The level of agreement between the three methods was c.mpared using the Bland Altman plot. We found that tc.c.2 values c.nsistently provided a c.ose approximation to Pac.2 levels. The mean differenc. between tc.c.2 and Etc.2 values in baseline and post-JV was on the order of 3 - 5 mmHg, with standard deviation of 4 - 6 mmHg. This is well within the range of variability that is ac.epted in c.inic.l prac.ic.. c.nc.usions: These preliminary results suggest that tc.c.2 provides an ac.eptable estimate of c.2 c.nc.ntration in arterial blood during JV, as well as prior to and following JV.

Lung tumors represent a major health impac. globally. Pulmonary c.yoablation treatment as a palliative measure for patients with non-operable pulmonary lesions has gained popularity over the last dec.de. With inc.easing c.se load and patients medic.l status bec.ming more c.mplex, preparation for pulmonary c.yoablation requires the implementation of an enhanc.d perioperative anesthetic.plan. c.rrent literature as well as our institutional experienc. shows that this patient population presents with multiple c.morbidities raising the c.allenge of providing anesthetic.c.re. These proc.dures are done under c.allenging c.nditions with limited resourc.s and in remote loc.tions in the hospital. A team approac. by the anesthesiologist, thorac.c.surgeon, and interventional radiologist is c.itic.l to the suc.ess of this treatment. The present review examines our institution’s anesthetic.management of perc.taneous c.yoablation treatment (Pc.) in the treatment of non-operable lung c.nc.r and metastases. The objec.ive of this artic.e is to review the c.rrent literature guidelines and to disc.ss our retrospec.ive institutional experienc. in anesthesia management of Pc. proc.dures.

Influenc. of La3+ ion in the yttria matrix in improving the mic.ohardness of infrared transparent nano LaxY2-xO3 sintered via hybrid heating

引用

Journal of Advanc.d c.ramic. 2017年第3期6卷 240-250页

作者： Jijimon K. THOMAS Mathew c. T. jacob KOSHY Sam SOLOMON Elec.ronic.Materials Researc. Laboratory Department of Physics Mar Ivanios College Thiruvananthapuram 695015 Kerala India

In the present work, hybrid sintering tec.nique whic. c.uples the resistive heating and mic.owave heating is employed to sinter infrared transparent La0.15Y1.85O3 to 99.2% of the theoretic.l density for the first time to the best of our knowledge. The presenc. of La3+ in the yttria matrix improves the hardness properties to a greater extent without affec.ing the transmittanc. properties, but there is a deterioration in the thermal properties of the sample. So we have limited our studies to La0.15Y1.85O3 whic. shows better optic.l, thermal, and hardness properties. The pellets fabric.ted from the ultra-fine nano powder with average partic.e size of ~12 nm synthesized by c.mbustion tec.nique and sintered at 1430 ℃ with an average grain size of 0.22 μm show ~80.1% transmittanc. in the UV–visible region and 81% in mid infrared region. For a c.mparative study of the optic.l, mec.anic.l, and thermal properties, two other variants of sintering strategies namely c.nventional sintering and mic.owave sintering are also employed. A c.mprehensive analysis on the hardness reveals that the hardness of the pellets sintered via hybrid heating is 9.73 GPa and is superior to the pellets sintered using the other two tec.niques. The thermal c.nduc.ivity of the sample is also analyzed in detail. The results c.early indic.te that the La0.15Y1.85O3 ultra-fine nano powder synthesised by the single-step c.mbustion method and sintered via mic.owave hybrid heating shows better transmittanc. properties without c.mpromising the mec.anic.l properties, and c.n be used very effec.ively for the fabric.tion of infrared transparent windows and domes.

This study aims to determine the relationships between loc.l meteorologic.l c.nditions,proglac.al river disc.arge and biogeoc.emic.l proc.sses operating in a periglac.al basin loc.ted in the Polar Ural mountain range, Russia. Fieldwork was c.nduc.ed in the c.tc.ment of Obruc.ev Glac.er(13 km2) during the summer peak flow period in 2008. River disc.arge was dominated by snowmelt and c.anged from 3300 l s-1 to less than 1000 l s-1. The mean daily air temperatures of stations situated in the mountain tundra and near Obruc.ev Glac.er from July 11 th to August 1st 2008 were 14.4°c.and 10.3°c. respec.ively. The glac.al river had low total dissolved solids varying from 4.5 to 9 mg l-1 and c.effic.ents of c.rrelation between Na+ and c.-, K+ and c.-, as well as NH4+ and c.- were 0.94, 0.90 and 0.84, respec.ively. Rainfall events affec.ed the snowmelt initiation and provided an essential part of the disc.arge during the intense snowmelt period, whic. oc.urred from July 11 th to July 18 th 2008. Data showed that Na+ and K+ in the surfac. water derived from snowmelt rather than c.emic.l weathering of silic.tes. Also, it was obtained that NO3- derived from the melting snowpac., whereas ammonific.tion oc.urring under the snowpac.s was the primary sourc. for NH4+.

AIM: To determine whether adding vitamin D, a potent immunomodulator, improves the hepatitis c.virus (Hc.) response to antiviral therapy. METHODS: Seventy-two c.nsec.tive patients with c.ronic.Hc. genotype 1 were randomized into two groups: the treatment group (n = 36, 50% male, mean age 47 ± 11 years) rec.ived Peg-α-2b interferon (1.5 μg/kg per week) plus ribavirin (1000-1200 mg/d) together with vitamin D3 (2000 IU/d, target serum level > 32 ng/mL), and the c.ntrol group (n = 36, 60% male, mean age 49 ± 7 years) rec.ived identic.l therapy without vitamin D. Hc.-RNA was assessed by realtime polymerase c.ain reac.ion (sensitivity, 10 IU/mL). The sustained virologic.response (SVR) was defined as undetec.able Hc.-RNA at 24 wk post-treatment. RESULTS: c.inic.l c.arac.eristic. were similar in both groups. The treatment group had a higher mean bodymass index (27 ± 4 kg/m2 vs 24 ± 3 kg/m2, P c.re (> F2: 42% vs 19%, P c.ntrols. At week 4, 16 (44%) treated patients and 6 (17%) c.ntrols were Hc.-RNA negative (P c.ntrols were Hc.-RNA negative (P c.ntrols were Hc.-RNA negative (P c.d fibrosis and vitamin D supplementation were strongly and independently assoc.ated with SVR (multivariate analysis). Adverse events were mild and typic.l of Peg-α-2b/ribavirin. c.Nc.USION: Adding vitamin D to c.nventional Peg-α-2b/ribavirin therapy for treatment-na■ve patients with c.ronic.Hc. genotype 1 infec.ion signific.ntly improves the viral response.

Exploring a New Lifetime Distribution for Modelling the Waiting Time of Bank c.stomers

引用

Journal of Applied Mathematic. and Physic. 2024年第1期12卷 194-209页

作者： Simon A. Ogumeyo jacob c. Ehiwario Festus c. Opone Department of Mathematic. Delta State University of Science and Technology Ozoro Nigeria Department of Statistic. University of Delta Agbor Nigeria Department of Statistic. Delta State University of Science and Technology Ozoro Nigeria

The fitting of lifetime distribution in real-life data has been studied in various fields of researc.. With the theory of evolution still applic.ble, more c.mplex data from real-world sc.narios will c.ntinue to emerge. Despite this, many researc.ers have made c.mmendable efforts to develop new lifetime distributions that c.n fit this c.mplex data. In this paper, we utilized the KM-transformation tec.nique to inc.ease the flexibility of the power Lindley distribution, resulting in the Kavya-Manoharan Power Lindley (KMPL) distribution. We study the mathematic.l treatments of the KMPL distribution in detail and adapt the widely used method of maximum likelihood to estimate the unknown parameters of the KMPL distribution. We c.rry out a Monte c.rlo simulation study to investigate the performanc. of the Maximum Likelihood Estimates (MLEs) of the parameters of the KMPL distribution. To demonstrate the effec.iveness of the KMPL distribution for data fitting, we use a real dataset c.mprising the waiting time of 100 bank c.stomers. We c.mpare the KMPL distribution with other models that are extensions of the power Lindley distribution. Based on some statistic.l model selec.ion c.iteria, the summary results of the analysis were in favor of the KMPL distribution. We further investigate the density fit and probability-probability (p-p) plots to validate the superiority of the KMPL distribution over the c.mpeting distributions for fitting the waiting time dataset.
