Impacts of the Contradictory Factors in Algal Co2 Sequestration with Sustainable Biofuel Benefit

Background The purpose would discover the impacts of the contradictory factors in application of algae in CO2 sequestration with sustainable biofuel benefit. The quantitively assessment model and approach have been established coupling upstream CO2 source and deliverables with downstream algal biofuel deliverables at the uniform algae level of Nannochloropsis oceanica, which would be benefit for algae biofuel deliverables choice. The functional units have been defined at energy consumption (MJ) per final mass product (algae, jet biofuels by three refining pathways, biodiesels by three refining pathways) and energy consumption (MJ) per final energy yield (algae, jet biofuels, biodiesels). Computational framework is classified into three sub-models, including CO2 source and deliverable model, algae cultivation and deliverable model, refining process and biofuel deliverable model. This life cycle assessment investigated the following impacts: transportation distances and purification modes with flue gas CO2 concentrations, lipid content with specific productivity and CO2 biofixation coupling the nutrient supply, final products including algae, jet biofuel and biodiesel.Results Coupling the influence of transportation distances and purification modes on the energy consumption, flue gas with a wide range of CO2 concentration was compared for two type deliverables including algal CO2, edible CO2. flue gas with low CO2 concentration is appropriate for on-site algal CO2 deliverable within 10km while flue gas with above 95% CO2 is flexible to transportation distance and appropriate for edible CO2 deliverable. Specific productivities and CO2 fixation both comply with negatively logarithmic relationship with lipid contents. Coupling the effects of algae specific productivity and CO2 evaporation loss, the total CO2 fixation efficiencies were investigated above 90% at below 28 % lipid but obviously decrease at above 40% lipid. The nutrient supply enhances specific productivity and protein content but with indirect energy consumption. The total energy consumptions of different target products with upstream CO2 source and algae to downstream biofuel were calculated quantitatively on edible algae and general algae.Conclusions Biodieselwet and HTL-HRJ jet biofuel performed the priorities in energy consumption. Lipid content and profile defined biofuel deliverables in quantity and quality. The LCA indicated that allocation is a crucial issue to balance energy, environment and economy decision on target product choice and by-products. Coupling solar energy utilization and by-product of bioactive nutrients effects, the positive energy gains have been investigated at a wide range of lipid contents despite of jet biofuel or biodiesel. The results would enhance the interests in both LCA and application of algae in CO2 sequestration with sustainable biofuel benefit.

Understanding the Time-Course of Nephrolithiasis Management

Purpose: The growing incidence of acute nephrolithiasis has increased the burden on healthcare. We sought to assess the time-course of acute stone disease treatment from symptom onset to spontaneous passage or definitive treatment to better characterize the current state of management and identify areas for improvement. Methods: We performed a retrospective review of patients treated for acute nephrolithiasis from August 2016 until February 2017. Patients were included if they had symptomatic renal or ureteral stones, evaluation by urology, and documented resolution by spontaneous passage or surgery. Primary outcome was the time from initial presentation at the Emergency Department (ED) to procedure or passage. Secondary outcomes included time to outpatient evaluation by urology and delays to procedure scheduling greater than 14 days. Results: 61 patients (41% female) met selection criteria. Median time from initial presentation to procedure or stone passage was 45 or 26 days, respectively. Median time from ED to clinic visit was 12.5 days. Time from clinic visit to procedure or spontaneous passage was 29 or 16 days, respectively. 38 patients (62%) had documented causes for delay in treatment. Of this cohort, 22 (58%) were due to provider availability issues, 8 (21%) had contraindications to surgery, and 8 (21%) had patient-related delays. Conclusion: Prolonged time to treatment of acute nephrolithiasis occurred in 30 (49%) of the cohort due to provider availability and patient- specific delays. Developing initiatives to expedite management through improved patient education and operating room availability may help reduce healthcare costs and patient discomfort. ,2020
Effect of Tanshione IIA on proliferation of human renal epithelial and secretion of collagen I induced by TGF-β_1

Objective To explore the effect of Tanshione IIA in preventing and treating renal interstitial fibrosis. Methods Human renal tubular epithelial( HK-2) cells were cultivated in vitro and divided into five groups: blank control group,TGF-β110 μg /L group,Tanshione IIA groups( low,medium,high dose),and each group was treated with corresponding drugs and reagents. The proliferation of HK-2 was detected by MTT and morphological changes of cells were observed by inverted phase contrast microscope. The content of collagen I was measured by ELISA. Results In TGF-β110 μg /L group,HK-2 cells were stimulated by TGF-β1and can be converted to fibroblast cells. After combined with Tanshione IIA,cells proliferation was restrained and the cells morphology were tending to the normal gradually. It was showed a significant dose-dependent. Secretion of collagen Ⅰ was stimulated by TGF-β1,with a significant difference between blank control group and TGF-β1group( P 0. 05). After combined with Tanshione IIA,expression of collagen Ⅰ was reduced,with dose-dependent manner.Conclusion Tanshione IIA can maintain the morphological stability of HK-2 cells,prevent cells develop into fibroblast cells,and inhibit cell proliferation and secretion of collagen Ⅰ induced by TGF-β1. Its mechanism may be association with the preventing and treating renal fibrosis by Tanshione IIA.
Determinants of Self-Reported Illness: An Experience from Social Health Insurance Program in Nepal

Even though the ultimate goal of social health insurance program is to increase the utilization of health services and reduce the health care expenditure, individuals in developing countries generally do not visit a healthcare provider or spend on healthcare unless they perceive themselves as ill. Thus, the determinants of such illness reporting could have practical significance in a setting, where the social health insurance program was first being implemented in Nepal. Philosophically, this study follows a post-positivism or empiricism research paradigm. The ontological assumption of this study is a singular reality and regarding the epistemological assumption, this study considers an objective reality, a deductive method of quantitative inquiry. A cross-sectional survey was performed among 6480 individuals from 1048 households located in 26 wards of Kailali district after twenty-one months of the implementation of health insurance program in Nepal. The sample was selected in two stages, first being the selection of wards and second being the households. Data analyses were mainly based on chi-square test and logistic regression analysis.

Fusão de Dados com Sensores com Geometria e Granularidade Distintas em Ambiente de Alta Taxa de Eventos

—One of the biggest challenges faced in multiple sensors systems is to provide an efﬁcient combining data method to obtain information of interest as accurately as possible. This work presents a linear technique to combine the information from redundant sensors, in order to minimize the effects of noise. Results obtained using sensors from the Hadronic Calorimeter of the ATLAS Experiment (CERN, Switzerland), to detect muon particles, have shown a reduction of 6% in the noise from the combination of neighboring channels. The method is also very effective in detecting and removing bad channels, increasing the robustness of the system.
Prognostic role of neutrophil-lymphocyte ratio in pediatric cystic adamantinomatous craniopharyngioma

Aim: Neutrophil-lymphocyte ratio (NLR) in peripheral blood, a hematological indicator of systemic infl ammation, has been shown as a prognocytic factor in various types of cancer. There is a limited number of studies evaluating the NLR in patients with craniopharyngioma (CP), and also the relationship between cystic component size and NLR in pediatric patients with CPs has not been investigated in the current literature before. This study aimed to investigate the relationship between NLR and cystic component size in pediatric patients with CP. Methods: The medical records of pediatric patients who underwent surgery for a sellar/ suprasellar cyst and whose pathology results indicated adamantinomatous CP between January 2008 and December 2019 were retrospectively reviewed. The cystic component size in the preoperative MRI with NLR in the preoperative peripheral blood count were measured. Results: 19 patients (10 females) – age range 2–17 years (mean 9 years) – were recruited. The minimum and maximum cystic component dimensions in MRI were 1.12 cm and 26.32 cm, respectively. A positive correlation was found between NLR and cystic component size (r = 0.992; P < 0.05), preoperative diabetes insipidus (r = 0.624), preoperative hydrocephalus (r = 0.825), and subtotal resection (r = 0.634). A negative correlation was found between NLR and gross total resection (r = −0.634) and preoperative anterior skull base surgery questionnaire scores (r = −0.729). Conclusion: Cystic component size and NLR are closely related in pediatric patients with CP. Preoperative NLR can not only refl ect local infl ammatory information on CP but also provide guidance in cystic component size, severity of symptoms, and prognosis. NLR ≥ 2 may have poor prognosis.
Laboratory Column Experiment to Evaluate Oxygen Diffusion through Covers with Capillary Barrier Effects Subjected to Freeze- Thaw Cycles

Environmental reclamation of mine waste disposal facilities often requires their confinement under engineered soil covers to control gas migration and water infiltration. In temperate climates, covers with capillary barrier effects (CCBE) are successfully used to control oxygen flux; these covers require a fine-grained material that acts as a moisture-retaining layer. In Nordic environments, where such natural fine-grained soils are not always available, soil or crushed rock-bentonite mixtures could be used instead. A key parameter in the design and performance evaluation of CCBE is the effective diffusion coefficient of oxygen (D e ) of the moisture-retaining layer. This paper aims at presenting the development of a laboratory column testing and interpretation method to evaluate the D e of a crushed rock-bentonite moisture-retaining layer in a CCBE and the effect of freeze-thaw cycles on D e . The numerical approach used to analyze the experimental diffusion test results allowed obtaining D e for various saturation conditions observed in the moisture-retaining layer. Preliminary results show that the initial measured value of D e increased by two orders of magnitude after 3 freeze-thaw cycles. Steady-state flux calculations based on the obtained D e showed that despite a good initial cover performance, the capacity of the tested cover to act as an oxygen barrier is reduced in the longer term. This study demonstrates that the proposed laboratory column oxygen diffusion test could be an effective tool to assess the performance of CCBE to control oxygen migration when exposed to cold climate conditions.
Improvement in Quality of Protein Crystals Grown in a High Magnetic Field Gradient

Space-based microgravity environments have been utilized to obtain a highly ordered crystal because of the lack of gravity-induced convection. A superconducting magnet-based quasi-microgravity is also expected to contribute to the enhancement of the quality of protein crystals. We here report a case study on protein crystallization using fifteen kinds of samples in a magnetic field gradient, which was sufficient for magnetic levitation of water droplets. In three cases, rod-type crystals were aligned perpendicular to the crystallization plate, exhibiting magnetic orientation parallel to the direction of the magnetic field. Five proteins showed improvement in crystal quality evaluated by the resolution limit in X-ray diffraction experiments and the overall B-factor of the crystal. Our data support the idea that the reduced-gravity environment produced by a high magnetic field gradient can be used to obtain enhanced-quality protein crystals, aiding in the determination of their precise crystal structures.
Defect Dynamics in Graphene

The experimental and theoretical study of graphene, two-dimensional (2D) graphite, is an extremely rapidly growing field of today's condensed matter research. Different types of disorder in graphene modify the Dirac equation leading to unusual spectroscopic and transport properties. The authors studied one of the disorders (i.e., grain boundaries) and formulated a theoretical model of graphene grain boundary by generalizing the two-dimensional graphene Dirac Hamiltonian model. In this model only, the authors considered the long-wavelength limit of the particle transport, which provides the main contribution to the graphene conductance. In this work, they derived the Hamiltonian in a rotated side dependent reference frame describing crystallographic axes mismatching at a grain boundary junction and showed that properties like energy spectrum are an independent reference frame. Also, they showed one of the topological property of graphene.

Adsorption of Cu (II) Ions from Aqueous Solution onto Chemically Prepared Activated Carbon from Theobroma cacoa

This present research was aimed at studying the adsorption characteristics of Cu(II) ions from aqueous solutions onto two samples of low-cost, cocoa shell-based activated Original Research Article British Journal of Applied Science & Technology, 4(36): 5021-5044, 2014 5022 carbons (CSBAC) using the batch adsorption mode. Activated carbon samples were obtained by chemical treatment via pyrolysis using phosphoric acid (PAA) and potassium hydroxide (PHA) as activation agent. Findings from the studies unveiled a pH at zeropoint charge (pHzpc) of 7.0 and 5.9 for PAA and PHA samples respectively. Contact time of 35 minutes for PAA and 15 minutes for PHA at pHmax = 4 by 0.1 g were observed. Optimum adsorption quantities were 62.2 mg/g for PAA and 42.2 mg/g for PHA for an initial metal ion concentration of 2400 ppm. The Langmuir model for PHA and Freundlich model for PAA best described the adsorption of Cu (II) ions from aqueous solution. The two CSBAC samples both obeyed pseudo-second order kinetics. Generally, these results indicate that CSBAC can be used as an effective and low-cost adsorbent for the removal of Cu (II) ions from aqueous solutions.
Successful use of Eltrombopag in a patient with refractory HIV-associated Immune Thrombocytopenic Purpura

Immune Thrombocytopenic Purpura (ITP) is not uncommon in patients with Human Immunodeficiency Virus (HIV) infection. This entity can be recurrent to standard therapy, which includes corticosteroids, intravenous immunoglobulins (IVIG) and highly active antiretroviral therapy (HAART). In immunocompetent patients with ITP, Eltrombopag, a thrombopoetin receptor agonist (TRA), has proven to be save and useful for increasing platelet counts and for treating patients with Hepatitis C virus (HCV) associated thrombocytopenia that need an interferon-based therapy. Safety and efficacy data with the use of TRAs in HIV-associated ITP are scarce, being a non-authorized indication. We report our one-year experience with Eltrombopag for treating a severe and refractory HIV-associated ITP.
Sarcopenia, bone mineral density, and vitamin D: EpiFloripa aging study 2013/2014

OBJECTIVE: To verify associations between osteopenia/osteoporosis and vitamin D and sarcopenia in the older adult population of Florianopolis, Brazil. METHODS: A cross-sectional population-based study, with 604 older adults (60 years and over). The appendicular muscle mass index (AMMI) was used to identify sarcopenia, with cutoffs of AMMI (Kg/m2) < 7.26 kg/m2 for men and < 5.50 kg/m2 for women indicating inadequate values (sarcopenia). The independent variable osteopenia/osteoporosis was measured using bone mineral density (BMD, g/cm2): T-Scores for whole body BMD, lumbar spine BMD, and femoral neck BMD, categorized as normal (BMD ≥ -1 SD) or osteopenia/osteoporosis (BMD < -1 SD from the mean of the young adult reference population). Fasting serum samples were collected and assayed using the microparticle chemiluminescence (CMIA)/Liaison method. Vitamin D concentrations of < 30 ng/mL were defined as hypovitaminosis. Crude and adjusted logistic regression analyses were performed. RESULTS: Osteopenia/osteoporosis in the lumbar spine and femoral neck were associated with higher odds of sarcopenia in women and men. Osteopenia/osteoporosis in the whole body was associated with sarcopenia in women only. Vitamin D was not associated with sarcopenia in either sex. CONCLUSIONS: Having osteopenia/osteoporosis is associated with sarcopenia in the older adult population.
POWER FOR PROCESSING APPLICATION FLOWS AND QUEUE SIZES IN MASS SERVICE SYSTEMS

The classical queuing theory studies time series processing under the assumption of sampling independence. However, the traffic of modern multiservice networks is usually strongly correlated and the methods of classical theory do not work. In this paper, we consider the cyclic process of queuing, conditional and unconditional mutual correlations. Conditional average values of queues are considered. The concept of processing power of the flow of applications in queuing systems (QS) is introduced. It is shown that the variable component of the indicated power is determined by the change in the load factor and corresponds to the conditional average size of the queue of applications in the QS.
Phytomolecules having flavone and napthofuran nucleus exhibited better binding G-score against protease and SPIKE protein of novel corona virus COVID-19

The present study aims to screen the different phytoconstituents and drugs for potential treatment of the corona virus COVID-19 and for specificity through virtual screening. The plant molecules selected were based upon traditional knowledge and are prescribed in the Indian system of medicine for infectious/ respiratory conditions. The three target proteins selected for the study are 3CLpro, PLpro, and SPIKE. These proteins have defined pathological roles in disease transmission. The virtual screening was carried out in these proteins using the GLIDE Schrödinger Maestro software version 11.9. 011. The efficacy was assessed by the calculated G-score of the ligand interaction with the amino acid side chains of the ligand binding domain. Molecules such as saponarin, mangiferin, and hesperidin exhibited better G-score with 3CLpro and PLpro. Similarly, diphyllin and tuberculatin exhibited better G-score for SPIKE protein. The reference anti malarial drug hydroxychloroquine showed better interactions with 3CLpro and PLpro. Similarly, protease inhibitors and antiviral drugs have shown interaction with 3CLpro specific protease protein. Interestingly, SPIKE protein ligands, diphyllin and tuberculatin from Justicia adhatoda (vasaka), were found to be unique and did not show affinity to protease inhibitor. It can be concluded, that the molecules having flavone scaffolds show better binding affinity with protease proteins 3CLpro and PLpro. SPIKE protein scaffold is different and showed better binding affinity with molecules having naptho-furan ring. The traditionally used plant phytoconstituents did not exhibit good binding affinity; however, we believe that a combination of these herbs might induce human immune system against microbial infection.
