Abstract Dehydration and oligomerization of ethanol to hydrocarbons was studied using a packed-bed reactor over HZSM-5 (SiO2/Al2O3=280 mol/mol) zeolite as catalyst. Nine experiments were performed at different temperature and weight hourly space velocity (WHSV) conditions. The experiments were conducted in three levels for both variables (T: 300, 350, and 410 °C) and (WHSV: 1.3, 3.7, and 7.9 h–1). For all the experiments, ethanol was dehydrated to ethylene; however, oligomerization only occurred at WHSV=1.3 h-1, where the yields to liquid hydrocarbons were 15, 25, and 10% at 300, 350, and 410 °C, respectively. The liquid hydrocarbon products were analyzed by copper metal corrosion, gum content, octane number, Reid vapor pressure, gas chromatography, and fractional distillation. The octane number was about 95 in all cases, higher than Ecuador premium gasoline octane number (92). These laboratory-scale findings provide good insights on the ethanol-to-gasoline approach that could be scaled up to the industry.

Silver nanoparticles (AgNPs) have been synthesized using Rhoeo discolor leaf extract as a reducing and stabilizing agent. AgNPs were synthesized by adding silver nitrate to the extract of Rhoeo discolor and incubating it in a boiling water bath. The change in color of the mixture from clear to yellow indicated AgNPs formation. The synthesized AgNPs were spherical and showed an absorption peak at around 410-420 nm. The size of particles was distributed from 92 to 485 nm with an average size of 176 nm, and the polydispersity index was 0.185. The stability test showed that synthesized AgNPs were stable for three months of storage at ambient temperature. The extract of Rhoeo discolor were responsible for reducing silver ion and stabilizing the synthesized AgNPs.

Introduction: Second hand smoke (SHS) is reported to cause 890,000 deaths annually worldwide. It is also a known cause of serious complications in pregnancy. The current study intends to fill in some of the knowledge gap for further research & effective public health interventions. Objective: To estimate the magnitude of exposure to second hand smoke and assess awareness about it among pregnant women visiting four selected tertiary care hospitals of Peshawar. Materials & Methods: A descriptive cross-sectional study was conducted at four tertiary hospitals of Peshawar from 1st January to 1st March 2018. Non-probability serial sample of 410 pregnant women was taken. A structured questionnaire was used to collect data. Data were analysed for descriptive statistics using SPSS version 22. Results: A total of 410 pregnant women were included. The mean age was 21 + 4 years; 149 (36.3%) of the total subjects were exposed to SHS, highest frequency (49%) being in age group 26-35 years. Exposure to SHS was highest (39%) among illiterate ladies; 92% of the subjects were exposed to SHS at home, the main source being their husbands (46%); 40.7% of the subjects were aware of the adverse effects of SHS on fetus, younger (p=0.01) & more educated women (p=0.001) being more likely to be aware. Conclusions: Exposure of pregnant women to second hand smoke is a public health concern in Peshawar, being more likely among younger, less educated, unaware women, and housewives.

410 Background: Prospectively collected data evaluating therapy for papillary mRCC are limited. RAPTOR (NCT00688753) evaluated the efficacy and safety of EVE as first-line therapy for papillary mRCC. Methods: Eligible pts had histologically confirmed type 1 or 2 papillary mRCC, ECOG PS ≤1, and no previous systemic therapy for mRCC. Central histology review was mandatory. EVE 10 mg/d was given until disease progression or intolerable toxicity. The primary end point was the PFS rate at 6 months assessed per RECIST 1.0 (central review) in the first 44 pts of the per-protocol population (PPFF; lack of centrally confirmed papillary histology was a protocol violation). Secondary end points included PFS, OS, and safety. Sensitivity (per protocol [PP] and ITT populations), supportive (local review), and subgroup (type 1 and 2 histology) analyses were performed. Results: 92 pts enrolled (median age, 60 y; 78% men). Among pts with papillary RCC per local review (99%), 58% had type 2 and 16% had type 1 (25% missing). Central review confirmed papillary histology in 76% of pts, 59% with type 2 and 33% with type 1 (9% missing). Reasons for discrepancies will be presented. Efficacy results are shown (Table). In the safety population (n=92), the most common grade ≥3 AEs were asthenia (11%), anemia (5%), and fatigue (5%). Conclusions: The RAPTOR study showed that EVE was well tolerated by and provided clinical benefit to pts with both type 1 and type 2 papillary mRCC, although both PFS and OS were longer in type 1. These results support further evaluation of EVE for pts with papillary mRCC. Clinical trial information: NCT00688753. [Table: see text]

Disaccharides have been used as an extender for dromedary camel semen (Bravo et al. 2000 Anim. Reprod. Sci. 62, 173-193). More recently we have investigated the effect of different concentrations of lactose extender on the viability of Bactrian camel spermatozoa (Mosafer et al. 2005 Reprod. Fertil. Dev. 17, 197). Considering the osmolality (316.1 � 1.48 mOsm/kg) and pH (7.4 � 0.03) of Bactrian camel semen (Mosaferi et al. 2005 Theriogenology 63, 92-101), the objective of this study was to investigate the effect of osmolality of sucrose extender on the viability of Bactrian camel spermatozoa. Sucrose at the concentrations of 9, 10, 11, 12, and 13% with osmolalities of 292, 331, 356, 386, and 410 mOsm/kg, respectively, were prepared. All extenders contained 20% egg yolk and antibiotics, with pH adjusted to 6.9. Semen was collected from camels with a sound history of semen quality and fertility (n = 3) using a modified artificial vagina and divided into different treatments after mechanical reduction of semen viscosity (3). Progressive forward motility of spermatozoa was examined at the time of semen collection and at 4, 12, and 24 h after incubation at 4�C. Data were analyzed using the GLM procedure in SAS/STAT after arcsin transformation. At the time of semen dilution, the progressive forward motility of spermatozoa was greater at osmolality of 331 (23%) compared with 292 (1%), 386 (6%), and 410 (3.5%) mOsm/kg (P < 0.05). No progressive forward motility of spermatozoa was noticed after 4 h incubation at 4�C at osmolalities of 292, 386, and 410 mOsm/kg. At this time, a significant decrease (P < 0.05) of progressive forward motility occurred at osmolalities of 331 (4%) and 356 (0.5%) compared with that of the time of dilution. After 12 and 24 h incubation at 4�C, no progressive forward motility of spermatozoa was detected in any of these extenders. In conclusion, 10% sucrose (331 mOsm/kg) at the adjusted pH of 6.9 was the most suitable concentration of this disaccharide for preserving Bactrian camel semen for less than 4 h under chilled conditions.

AbstractObjective:Epidemiological studies suggest that coffee consumption is inversely associated with all-cause and cause-specific mortality. Evidence from studies targeting non-white, non-Western populations is still sparse, although coffee is popular and widely consumed in Asian countries.Design:Population-based, prospective cohort study. We used Cox proportional hazards models with adjustment for dietary and lifestyle factors to estimate associations between coffee consumption and all-cause and cause-specific mortality. Dietary intake including coffee consumption was assessed only at baseline using a validated FFQ.Setting:A Japanese city.Participants:Individuals aged 35 years or older without cancer, CHD and stroke at baseline (n 29 079) and followed from 1992 to 2008.Results:From 410 352 person-years, 5339 deaths were identified (mean follow-up = 14·1 years). Coffee consumption was inversely associated with mortality from all causes and CVD among all participants, but not from cancer. Compared with the category of ‘none’, the multivariate hazard ratio (95 % CI) for all-cause mortality was 0·93 (0·86, 1·00) for <1 cup/d, 0·84 (0·76, 0·93) for 1 cup/d and 0·81 (0·71, 0·92) for 2–3 cups/d. The multivariate hazard ratio (95 % CI) for cardiovascular mortality were 0·87 (0·77, 0·99) for <1 cup/d, 0·76 (0·63, 0·92) for 1 cup/d and 0·67 (0·50, 0·89) for 2–3 cups/d. Inverse associations were also observed for mortality from other causes, specifically infectious and digestive diseases.Conclusion:Drinking coffee, even 1 cup/d, was inversely associated with all-cause mortality and mortality from cardiovascular, infectious and digestive diseases.

The emissions of a GE P-32 passenger locomotive was not adversely impacted by the use of B20 biodiesel blended fuel. Amtrak, with the support of the Federal Railroad Administration operated a P-32 passenger locomotive in revenue service for a period of 12 months, operating on a blend of 20% pure biodiesel and 80% #2 ultra low sulfur diesel (ULSD) fuel. The P-32 locomotive used in the biodiesel demonstration was a Tier 0 12-cyclinder engine, built in 1991. The locomotive was operated on the Heartland Flyer route, providing passenger train service between Oklahoma City, OK and Fort Worth, TX. The biodiesel test locomotive maintained the Heartland Flyer train schedule 331 times by providing one roundtrip daily between the two cities, for a total of 410 miles. Following the in-service trial, the locomotive underwent emissions testing at the GE Transportation’s locomotive emissions test facility in Erie, PA. The locomotive was tested according to the US Code of Federal Regulation (CFR) Title 40 Part 92. The test results show that operating the P-32 passenger locomotive on B20 biodiesel blended fuel for 12 months did not adversely affect the emissions of the locomotive. The paper will outline the procedure and results from the emissions testing of the B20 fuel in a passenger locomotive engine, after having used B20 fuel for 12-months in revenue service. The paper will show that the locomotive B20 emissions for hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx) particulate matter (PM), and smoke opacity were not adversely affected, and were well below the EPA locomotive emissions limit. Due to warranty issues, GE permitted use of B20 for this study however GE does not approve use of B20 under its warranty provisions.

Abstract High gas volume fractions (GVFs) decrease the pressure boosting capacity of electric submersible pumps (ESPs). To prevent this, advanced gas handlers, helico-axial-pumps, etc., may be installed upstream of the pump, but these equipment can be expensive. This study presents results of testing different impeller combinations up to 90% intake GVF. The findings present a potential economical option for managing high GVF flows in ESP operation, beneficial to boosting and maximizing production from a field asset. The pump used was a two-stage, radial-type centrifugal pump with 3.78-inch impeller diameter operating at 3400 RPM. Three impeller pairs were used: P0 (no hole in any impeller blades), P1 (holes only in second stage impeller blades), and P2 (holes in first and second stage impeller blades). Water flow rates were fixed from 75 to 550 barrels per day (BPD), and air flow rates varied to give intake GVFs between 10% to 92% for average fluid temperatures about 25°C. The corresponding differential pressures across the pump were measured and compared to one another. The results showed that for all impellers, the differential pressure across the pumps decreased with increasing GVF. At 75 BPD, pump P0 attained zero differential pressure at about 72% GVF. The impellers in P1 and P2 were able to extend its operation to reach zero differential pressure at 90% and 90% GVF, respectively. When the liquid flow rate was increased to 275 BPD, the differential pressures in P0, P1 and P2 reached zero at about 36%, 38% and 41%, respectively. Increasing the liquid flow rate even further to 410 BPD, results in zero differential pressure at about 26%, 30% and 29% GVF for P0, P1, and P2, respectively. The general trend is that the GVF at which the differential pressure reaches zero decreases with increasing liquid volume flow rate. At lower liquid volume flow rates, holes drilled in the impeller blades significantly extend the pump's GVF handling capability by homogenizing the flow at the inlet of the centrifugal pump. Since the gas-handling performance of a radial-type pump was enhanced, it may be concluded that the performance will be even more favorable for a mixed-flow or axial-flow pump, especially at higher rotational speeds and intake pressures than in these tests. This study highlights the importance of pursuing economical alternatives to extend the performance envelope of a centrifugal pump operating in high GVF flows. The findings from this work imply that with appropriate modifications to ESP impellers, their operating envelopes may be increased using cost-effective methods. This opens opportunities for stakeholders to maximize production from field assets with very high-gas content, and increase the economic bottomline for the operator.
