Technical feasibility of biodiesel production from virgin oil and waste cooking oil: Comparison between traditional and innovative process based on hydrodynamic cavitation

Biodiesel production calls for innovative solutions to turn into a competitive process with a reduced environmental impact. One of the process bottlenecks stands in the immiscibility of oil and alcohol as raw materials, so mixing process largely impacts the overall process cost. This process step, if carried out by using hydrodynamic cavitation, has the possibility to become a benchmark for large scale applications. In this paper a process analysis of biodiesel production scheme is developed starting from two different feedstocks, virgin oil and waste cooking oil. At the first the traditional process scheme has been simulated, in a second simulation, the reactor for the biodiesel production is interchanged with a hydrodynamic cavitation reactor. In the paper, the comparison between the traditional and innovative process by using life cycle costing approach has been presented, thus providing indications for industrial technological implementation coming from a professional tool for process analysis. It is worth noting that the introduction of hydrodynamic cavitation reduces of about 40% the energy consumption with respect to the traditional process. As regards the total treatment costs, when using virgin oil as feedstock, they were in the range 820-830 6/t (innovative and traditional process, respectively); while starting from waste cooking oil the costs decreased of about 60%, down to 290-300 6/t (innovative and traditional process, respectively).

Active and intelligent biodegradable packaging films using food and food waste-derived bioactive compounds: A review

Background: The growing environmental concern of plastic packaging disposal has led to the innovation of biodegradable biopolymers. Consumer demand and health concern further necessitate the emergence of active and intelligent packaging system to monitor the quality of packed food. Whereas, the use of chemical dyes as an indicator in smart packaging is not suitable for food packaging because of their high toxicity and harmful effects on human health and the environment. Hence, the researchers are focused on natural pigments derived from plants and food waste as indicating substance in biodegradable packaging and also for the valorization of food waste. Scope and approach: This paper summarizes the research on the utilization of naturally derived food- and food waste-based pigments (anthocyanins, curcumin, betalains, carotenoids, chlorophyll, brazilin, quercetin, etc.) with biopolymeric matrices (starch, cellulose, chitin, gums, agar, etc.) to fabricate smart biodegradable films, for effective monitoring of spoilage and quality of meat products, seafood, milk, and others. Key Findings and Conclusions: The results show that the smart packaging material developed by the biopolymers with plant-based pigment has the potential to replace the traditional plastic packaging materials. The extracted from food and food waste act as an indicator in smart packaging and promotes the valorization of food waste. The biodegradable packaging is economical, safe, non-toxic, sensitive, and natural pigments act as a quality indicator in packaging systems. Further, these packaging films can be optimized and commercialized and to be employed as active and intelligent packaging for visual quality evaluation of fresh food products.

Smoking cessation in head and neck cancer patients: Factors influencing successes and failures

Introduction This study investigated the smoking behaviours and cessation rates of head and neck cancer (HNC) patients, and their barriers and facilitators to cessation. Method The study used a mixed methods, sequential explanatory design. The quantitative data were collected at baseline (around time of cancer diagnosis) via a survey prior to commencement of treatment. Participants identified as current smokers at baseline were then followed up to determine their smoking status after treatment and asked to participate in one-on-one, semi-structured interviews. Results Sixty-four participants with HNC were recruited, with 29 classified as current smokers. The 7-day point prevalence cessation rate for current smokers was 72% at 1-month follow-up, and 67% at 3 months, while continuous smoking cessation was 54% at 1 month, and 42% at 3 months. Participants who continued smoking were found to consume more alcohol (P = 0.032), be in a lower stage of change (pre-contemplation or contemplation stages of the transtheoretical model) at baseline (P = 0.012) and be less confident in being able to cease smoking (P = 0.004). Qualitative analysis revealed 5 key themes associated with smoking cessation: the teachable moment of a cancer diagnosis and treatment, willpower and cessation aids, psychosocial environment, relationship with alcohol and marijuana, and health knowledge and beliefs surrounding smoking and cancer. Conclusions This study demonstrates that the majority of HNC patients achieve smoking cessation, but relapses are common. Cessation programmes should be developed that are comprehensive, sustained and address factors such as alcohol, marijuana and depression.

Radiological and physical properties of tissue equivalent mammography phantom: Characterization and analysis methods

This article provides methods to fabricate and characterize tissue equivalent properties of mammography phantom. The characterized properties are elemental composition, effective atomic number, electron density, attenuation coefficient and CT number. Polyvinyl alcohol (PVAL), ethanol solution and graphite powder were used to develop samples of breast phantoms. First, the microstructure and elemental composition of the phantom materials were acquired from the field emission scanning electron microscopy (FESEM). FESEM micrography was a good analytical technique to indicate void spaces within the phantom. Next, the effective atomic number and electron density were calculated from the percentage of elemental composition based on the energy dispersive X-ray analysis (EDXA). Mayneord’s formula and the Phy-X/ZeXTRa software were used to evaluate the effective atomic number. The calculations show that the effective atomic number ranged from 7.137 to 7.264 and 6.75-7.05 for Mayneord and Phy-X/ZeXTRa approach respectively. The electron density ranged from 3.191-3.209 x 10(23)/g. These values were found to be in good agreement with water and breast tissue by ICRP and AAPM standards. Then, the mass attenuation coefficients of the PVAL were calculated based on the transmission of low photons by using X-ray fluorescent (XRF) technique at 16.61-25.26 keV. The mass attenuation coefficient values were found to be close to water and breast tissue when results were compared to XCOM values. Finally, CT images were acquired to measure CT numbers, which were found to be near to CT number of breast tissues, -21.40 to 24.13 HU. Based on the ICRP, AAPM, BIRADS and XCOM standards, the study successfully showed methods to fabricate and characterized mammography phantoms.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5675-51-4, you can contact me at any time and look forward to more communication. Recommanded Product: 5675-51-4.

Some studies on the mutual diffusion, Joule-Thomson inversion curve and virial coefficients of binary mixtures containing diethylamine and (C-5 – C-9) 1-alkanol

In this study, second and third virial coefficients and the Joule-Thomson inversion curves for the binary mixtures of diethylamine (DEA) with 1-pentanol up to 1-nonanol were calculated regarding the Peng-Robinson-Stryjek-Vera (PRSV) equation. Experimental densities were used to calculate the adjustable parameters of the PRSV equation. The estimation of the thermodynamic factor for the binary systems from the COSMO-RS model shows that the considered mixtures exhibit a negative deviation from Raoult’s Law. Besides, the diffusion coefficients for the binary mixtures in the whole composition range were determined regarding experimental viscosities. The results were analyzed to gain information about the liquid structure in the binary mixtures. It has been shown that intermolecular forces between DEA and 1-alkanol, which changes with the alcohol chain length, have a significant impact on the above-mentioned parameters. The investigation has shown that increasing the alcohol chain length reinforces the strength of intermolecular interactions. (C) 2020 Elsevier B.V. All rights reserved.

Brain-Derived neurotrophic factor Va166Met induces female-specific changes in impulsive behaviour and alcohol self-administration in mice

Substance use disorders are a debilitating neuropsychiatric condition, however it remains unclear why some individuals are at greater risk of substance use disorders than others and what genetic factors determine such individual differences. Impulsivity appears a promising candidate endophenotype to bridge the gap between genetic risk and addiction. Brain-derived neurotrophic factor (BDNF), and in particular the BDNFval66Met polymorphism, has been suggested to be involved in both impulsivity and substance use disorders, however results so far have been inconsistent. To investigate the role of BDNF, and more specifically the BDNFval66Met polymorphism, in both impulsivity and operant alcohol self-administration using the same animal model. Separate cohorts of humanized Val66Met transgenic mice were assessed for either trait impulsivity in the 5-choice serial reaction time (5-CSRT) touchscreen task, or propensity towards obtaining ethanol in an operant paradigm. It was found that female hBDNE(val/val) mice exhibited both greater impulsivity compared to hBDNF(Met/Met) mice of the same sex as shown by a higher number of premature responses at one of three increased inter-trial intervals tested in the 5-CSRT task, and a greater propensity toward stable ethanol self-administration relative to male mice of the same genotype in the operant paradigm. By contrast, male mice showed no difference between genotypes in impulsivity or stable ethanol self-administration. The hBDNF(Met/Met) genotype appears to sex-specifically alter aspects of both impulsive behaviour and addiction propensity. These results suggest that impulse behaviour may be a possible predictor of addiction risk.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 100-86-7. Application In Synthesis of 2-Methyl-1-phenyl-2-propanol.

Heating temperature dependence of molecular characteristics and biological response for biomass pyrolysis volatile-derived water-dissolved organic matter

The utilization of biomass pyrolysis volatile-derived water-dissolved organic matter (WOM, often called wood vinegar) determines sustainable recycling of biomass. Further, pyrolysis temperature significantly controls the cracking of biomass components, resulting in various molecular compositions and biological responses of WOM. Although it has been widely used in the agriculture, the relationship between molecular compositions and biological responses affected by heating temperature is still unclear. Here, it was observed that the WOM concentration increased with increasing temperatures and the pyrolysis of 1 g biomass can generate similar to WOM with 36.24 mg C. Moreover, with increasing pyrolysis temperatures, the generated WOM consisted of more phenols but fewer alcohols, furans, adds, and ketones, and demonstrated characteristics of higher aromaticity and lower m/z molecular weight. Due to the enhanced polarity, high temperatures promoted the solubility of WOM. Germination tests show that low pyrolysis temperatures-derived WOM (< 400 degrees C) with large-molecular-weight and low oxygen-containing (low O/C-wa) promoted plant growth, while high temperatures-derived WOM (> 400 degrees C) with small-molecular-weight and high oxygen-containing (high O/C-wa) inhibited growth. These results suggest that WOM can be separately collected at different pyrolysis temperatures to achieve sustainable recycling of pyrolysis volatile. (C) 2020 Elsevier B.V. All rights reserved.

Thromboembolism, mortality, and bleeding in 2,435,541 atrial fibrillation patients with and without cancer: A nationwide cohort study

Background The number of patients with atrial fibrillation (AF) and cancer is rapidly increasing in clinical practice. The impact of cancer on clinical outcomes in this patient population is unclear, as is the performance of the HAS-BLED (Hypertension, Abnormal Renal/Liver Function, Stroke, Bleeding History or Predisposition, Labile INR, Elderly, Drugs/Alcohol) and CHA(2)DS(2)-VASc (Congestive Heart Failure, Hypertension, Age >= 75 years, Diabetes Mellitus, Stroke or Transient Ischemic Attack, Vascular Disease, Age 65 to 74 Years, Sex Category) scores. Methods This was an observational, retrospective cohort study including 2,435,541 adults hospitalized with AF. The authors investigated the incidence rates (IRs) of all-cause and cardiovascular mortality, ischemic stroke, major bleeding, and intracranial hemorrhage (ICH) according to the presence of cancer and cancer types. Results Overall, 399,344 (16.4%) had cancer, with the most common cancers being metastatic, prostatic, colorectal, lung, breast, and bladder. During a mean follow-up of 2.0 years, cancer increased all-cause mortality (hazard ratio [HR], 2.00; 95% confidence interval [CI], 1.99-2.01). The IR of ischemic stroke was higher with pancreatic cancer (2.8%/y), uterine cancer (2.6%/y), and breast cancer (2.6%/y), whereas it was lower with liver/lung cancer (1.9%/y) and leukemia/myeloma (2.0%/y), in comparison with noncancer patients (2.4%/y). Cancer increased the risk of major bleeding (HR, 1.27; 95% CI, 1.26-1.28) and ICH (HR, 1.07; 95% CI, 1.05-1.10). Leukemia, liver cancer, myeloma, and metastatic cancers showed the highest IRs for major bleeding/ICH. Major bleeding and ICH rates progressively increased with the HAS-BLED score, which showed generally good predictivity with C indexes > 0.70 for all cancer types. The CHA(2)DS(2)-VASc score’s predictivity was slightly lower in AF patients with cancer. Conclusions Cancer increased all-cause mortality, major bleeding, and ICH risk in AF patients. The association between cancer and ischemic stroke differed among cancer types, and in some types, the risk of bleeding seemed to exceed the thromboembolic risk.

Kidney Function After Liver Transplantation in a Single Center

Background: Renal dysfunction in the peri-transplant period appears to complicate both short- and long-term outcome of liver transplantation (LT). The aim of this study was to analyze the impact of selected clinical features in the peri-liver transplant period, as well calcineurin inhibitor, particularly tacrolimus given after LT, on kidney function in a single liver transplant center’s experience. Material/Methods: A total 125 consecutive liver-grafted individuals (82 M, 43 F), mean age 50 +/- 13 y (with alcohol-related liver dis- ease in 48 (38%) patients) were included into the study. Their clinical data were collected in the database until 46 months of follow-up, and the Python packages Pandas (version 0.22.0) and scikit-learn (version 0.21.3) were used for data analysis. Results: More advanced liver disease as judged by Child-Pugh class and MELD score differed significantly patients with preserved (serum creatinine SCr <1.5 mg/dL) and impaired (SCr >= 1.5 mg/dL) kidney function before LT. Older age and higher SCr pre-LT were associated with higher levels of SCr after LT in 2 time-points. SCr before LT was correlated with delta SCr for the highest and last recorded value (P<0.0001). Higher amounts of transfused colloids during surgery were associated with increased delta SCr for the highest value (P=0.019) after grafting in logistic regression analysis. There were no associations between SCr after LT and duration of anhepatic phase, urine output <= 100 mL/h, or post-reperfusion syndrome during transplantation (all P>0.05). There were no associations between SCr after LT and tacrolimus trough levels in analyses of correlations and linear regression analyses (all P>0.05). Conclusions: We found that pretransplant serum creatinine was the only factor affecting kidney function after LT in our liver transplant center. The restricted fluid policy was safe and effective in terms of long-term renal function. The role of kidney-saving immunosuppressive protocols in preserving renal function long-term after LT was also confirmed.

COVID-19 highlights the pitfalls of reliance on the carceral system as a response to addiction

People who are incarcerated are likely to meet criteria for at least one substance use disorder and need access to treatment. Access to such interventions was limited prior to the COVID-19 pandemic and has almost certainly been restricted further due to implementation of procedures intended to stop the spread of the virus. In this brief commentary, we discuss how COVID-19 has revealed the already tenuous access that people who are incarcerated have to behavioral health services, and the pitfalls of reliance on the U.S. carceral system as a response to addiction.Y
