Solid-Free Flexible Colloidal Completion Fluid with Variable Density for Gas Well Completion in High-Temperature and High-Pressure Reservoirs: Experimental Study and Pilot Test
Authors: Jia Hu , Niu Cheng-Cheng , Dai Chang-Lou 
Published: December 2021

Summary
Despite the increasing contribution of renewables to global energy, fossil fuels such as oil and gas still play an important role in energy supply. The development of deep and ultradeep oil and gas reservoirs has become more urgent. Typically, the ultrahigh-temperature and high-pressure (HTHP) environment is a big challenge. Solid-free brine is often used as a weighting component of high-density well completion fluid in the process of well operation, but the large amount of free water can easily cause water blocking damage to the reservoir. Therefore, there is an urgent need to develop a high-density completion fluid system that can be used in HTHP reservoir environments with little free water. In this paper, based on the theory of dispersion, degradation, viscosity extraction, and viscosity stabilization of polymer flexible colloidal particles in brines, an ultrahigh-temperature (180°C)-resistant, solid-free flexible colloidal completion fluid (SFCCF) with variable density and low corrosion was prepared. It breaks through the classical Flory’s water absorption theory. The phosphate brine was selected as the weighting base fluid of SFCCF, and the flexible colloidal particles were saturated with the phosphate brine to improve the density of SFCCF, as well as to reduce free water to lower the potential of water blocking damage. The results show that the dynamic viscosity of SFCCF is adjustable and ranges from 27 to 690 mPa·s, and the density is adjustable in the range of 1 to 1.8 g/cm3. SFCCF is a typical pseudoplastic fluid with shear dilution property, which is the result of the network destruction and the shear deformation of the flexible colloidal particles. The pump rate vs. dynamic viscosity curve is drawn. Under the pump rate of 50 to 800 L/min, the dynamic viscosity of SFCCF (1.2 to 1.7 g/cm3) is less than 40 mPa·s. In addition, SFCCF is viscosity stable for at least 4 days at 180°C and has excellent clay swelling resistance and reservoir fluid compatibility. Finally, SFCCF provides good reservoir protection and rock carrying capabilities and has the advantage of low cost. The successful application of SFCCF in a high-pressure gas well in the East China Sea is summarized, and some recommendations are proposed. The developed SFCCF can significantly reduce water blocking damage in HTHP well operations, providing a new avenue for HTHP well completions.

Published: December 2021

Abstract
Bacterial Cellulose (BC) production is still considered expensive and challenging for industries. Herein, BC was produced through an acetic acid bacteria isolated from the kombucha consortium and an extract from acerola juice-industrial waste. The isolated bacterium was characterized through different assays (biochemical characterization and 16S rRNA gene) being identified as Komagataeibacter rhaeticus. BC production with static cultivation mode by the isolated strain was compared using traditional Hestrin-Schramm (HS) medium and acerola waste (AC) (5% w/v). The kinetic behavior of BC production was slightly higher in the HS medium reaching 2.9 g/L after 12 days of fermentation, while 2.3 g/L in the AC medium. Minor differences were observed between crystallite size and d-spacing, highlighting BC produced by the AC medium with higher crystallinity of 93.9% and two-fold breaking stress resistance in comparison with the conventional medium, with high-temperature stability and economically feasible, promissory results for further application of this synthetized cellulose obtained from industrial residues.

Abstract
Based on the Lagrange equation, the motion equation of a rod fastened rotor-bearing system considering the damping of the contact interface is established. The numerical method is employed for numerical analysis. The bifurcation diagram, time series, frequency waveform, phase spectrum and Poincare map are used to illustrate the nonlinear dynamic behaviour. The transient responses during acceleration and deceleration are calculated to reveal the dynamic behaviour of the system. The numerical results hold that since the oil film is nonlinear, the system presents obvious bistable behaviour and a jumping phenomenon. In addition, a test bench of the rod fastened rotor-bearing system is built. The bistable behaviour and jumping phenomenon are experimentally proven, and the effect of the eccentric distance of the rotor on the bistable behaviour is experimentally explored. The results of this paper can be used for the basic design and fault diagnosis of rod fastened rotors.
Physical Exercise, Social Integration, and Urban Hukou Acquisition Decision-Making in China's Floating Population
Authors: Lu Chong , Wu Ailin 
Published: December 2021

Abstract
This paper uses data from the 2014 and 2016 China Labor Force Survey to investigate the relationship between physical exercise, social integration and urban hukou acquisition decision-making in the floating population. We find that physical exercise and social integration can directly promote the acquisition of urban hukou in floating populations, and physical exercise promotes the acquisition of urban hukou in floating populations by increasing their degree of social integration. So, social integration is the intermediary between the floating population's physical exercise and urban hukou acquisition decision-making. Specifically, the mediating effect is most pronounced in the non-agricultural and female floating population. The results suggest that the construction of amenities for physical exercise and communal physical activities can not only promote the development of a harmonious society, but also effectively encourage the floating population to acquire urban hukou in their city of work and promote the development of the new urbanization of China.JEL classifications: G80-05, J15, R23

Abstract
Background: Personalized diet counselling, as part of lifestyle change programs for cardiometabolic risk conditions (combinations of prediabetes or type 2 diabetes, hypertension, dyslipidemia and high waist circumference) has been shown to reduce progression to type 2 diabetes overall. To identify key process of care measures that could be linked to changes in diet, we undertook a secondary analysis of a Canadian pre-post study of lifestyle treatment of metabolic syndrome (MetS). Diet counselling process measures were documented and association with diet quality changes after 3 months were assessed. Results of the primary study showed 19% reversal of MetS after one year. Methods: Registered dietitians (RDs) reported on contact time, specific food behaviour goals (FBG), behaviour change techniques (BCT; adapted from the Michie CALO-RE taxonomy) and teaching resources at each contact. Diet quality was measured by 2005 Canadian Healthy Eating Index (HEI-C) and assessed for possible associations with individual BCT and FBG. Results: Food behaviour goals associated with improved HEI-C at 3 months were: poultry more than red meat, increased plant protein, increased fish, increased olive oil, increased fruits and vegetables, eating breakfast, increased milk and alternatives, healthier fats, healthier snacks and increased nuts, with an adverse association noted for more use (> 2 times/ 3 months) of the balanced meal concept (F test; p<0.001). Of 16 BCT, goal setting accounted for 15% of all BCT recorded, yet more goal setting (> 3 times/3 months) was associated with poorer HEI-C at 3 months (F test; p=0.007). Only self-monitoring, feedback on performance and focus on past success were associated with improved HEI-C. Conclusions: These results identify key aspects of process that impact diet quality. Documentation of both FBG and BCT is highly relevant in diet counselling and a summary diet quality score is a promising target for assessing short-term counselling success.

Abstract
The present study was on management of Alternaria leaf spot caused by Alternaria alternata in Asalio. The disease was found to be very severe in all Asalio growing areas causing heavy destruction. The main aim of this investigation was to find out effect of age of the host, inoculum density in Alternaria leaf spot disease development and molecular identification of pathogen. The result shows that the susceptibility in Asalio increased with increase in age on inoculatios of A. alternata. Maximum disease was obtained in the plants ageing 40 DAS with PDI 55.60 per cent. Among the variously examined levels of inoculum concentrations. The two lower concentrations 1 × 101 and 1 × 102 conidia ml-1 exhibited significant difference in the PDI (20.00 and 31.20 respectively) within each other. 1 × 103 and 1 × 104 conidia ml-1 inoculum levels were found to be significantly at par to each other with PDI (39.20 and 40.80 respectively). 1 × 103 conidia ml-1 inoculum concentration was optimum for causing highest level of disease. After inoculation of inoculum 1 × 103 conidia ml-1, typical leaf spot symptoms were observed on the leaves of Asalio plants. Disease severity according to the scale was 39.20%. For molecular identification, 650 bp internal transcribed spacer (ITS) regions (ITS1, 5.8s and ITS2) were amplified through polymerase chain reaction (PCR). The nucleotide sequences from ITS regions of the isolates were submitted to NCBI with GenBank accession numbers MA585375.

Abstract
Background Neoadjuvant chemotherapy (NAC) has been widely used to treat locally advanced and inflammatory breast cancer. The initial purpose of neoadjuvant chemotherapy in operable breast cancer is to reduce the tumor stage, achieve local control, and increase the conservative operation rate. Another significant advantage of using neoadjuvant chemotherapy is the early identification of unresponsive tumors, predicting the sensitivity of new drugs and promoting the development of new medicines and clinical trials. It is generally believed that complete pathological response (pCR) after neoadjuvant chemotherapy treatment predicts survival. The overall survival rate of patients who achieve pCR is much higher than that of patients who do not. Therefore, it is essential to predict the response of patients to neoadjuvant chemotherapy. There is increasing evidence that patient-derived organoids (PDOs) can be used in cancer research and drug development and for the personalized in vitro evaluation of drug responses.Method We generated a living organoid biobank from locally advanced breast cancer patients receiving neoadjuvant chemotherapy. These patients had three clinically common molecular types of breast cancer (luminal-type, triple-negative and HER2+ breast cancer). When the patient received clinical neoadjuvant chemotherapy, the organoids were treated with similar drugs, thereby simulating the situation of the patient receiving treatmentResult We successfully constructed organoids from breast cancer biopsies to simulate clinical treatment, demonstrating that viable tumoroid lines can be generated from a small sample of tissue. The phenotype of breast cancer organoid often agreed with the original breast cancer according to the blinded histopathological analysis of H&E stain tissue and organoid sections. Our clinical trial data confirm that the patient's response to chemotherapy closely matches the organoids’ response to drugs. The patient-derived organoids may identify breast cancer patients who respond to neoadjuvant chemotherapy and thereby improve initial care.Conclusion Our data indicate that patient-derived organoids can be used to predict the clinical response of breast cancer patients to neoadjuvant chemotherapy in vitro and to screen drugs that have different effects on different patients.
Multi-Platform Simulation of Infilled Shear-Critical Reinforced Concrete Frames Subjected to Earthquake Excitations
Authors: Huang Xu , Brodsky Alex 
Published: December 2021

Abstract
This paper proposes a multi-platform simulation method for seismic performance assessment of masonry infilled reinforced concrete (RC) frames, especially for those who tend to fail in shear during an earthquake due to inadequate reinforcing details. The method is based on a micro-macro modeling approach where a detailed finite element (FE) model of the RC frame is incorporated with a strut model of the infill wall. It takes advantage of the strut model in terms of computational efficiency and the FE model based on the Modified Compression Field Theory (MCFT) to capture the nonlinear behaviour of the RC frame with explicit modeling of the beam-column joint failure and shear failure of the frame. The proposed method is validated against previously tested frames subjected to lateral loads, and its advantages over the conventional struct models are demonstrated through both quasi-static and dynamic analyses.
Removal Mechanisms of Cr(VI) By Redox-Active Moieties on HNO3 Modified Biochar Under Different pH and O2 Conditions

Published: December 2021

Abstract
Nitric acid (HNO3) modified biochar (NBC) has been demonstrated to be a promising sorbent. However, the roles of their redox-active moieties (RAMs, i.e., environmentally persistent free radicals (EPFRs) and oxygen-containing function groups) in Cr(VI) removal under varying pH and O2 conditions remain poorly understood. In this study, HNO3 oxidation caused an obvious increase in specific surface area, porous volume, RAMs content, and surface potential of the biochar, leading to the more effective removal of Cr(VI) (with the removal rate reached 100% at pH 2.0) than that of the untreated biochar. Kinetics experiments revealed that O2 and pH are of great importance for the reduction efficiency and rate of Cr(VI). RAMs on NBC can either directly reduce Cr(VI)(predominant pathway) or activate O2 to produce •O2− for indirect Cr(VI) reduction. In addition, we examined the changes in the compositions of RAMs during the reaction by tuning the RAMs compositions using methanol and hydrogen peroxide. The results of electron paramagnetic resonance and X-ray photoelectron spectroscopy analysis demonstrated that the main electron donors on NBC were different at different pH values: oxygen-containing groups, e.g., –OH and C–O–C, played a dominant role in reducing Cr(VI) under acidic conditions while the neutral condition was beneficial to EPFRs-dominated reduction. This study investigated the roles of the EPFRs and oxygen-containing function groups on HNO3 modified biochar, which may provide new insights into the promoted reduction of Cr(VI) by applications of biochar.

Abstract
Biological treatment in wastewater treatment plants (WWTPs) releases high amounts of bioaerosols carrying a variety of pathogens. Quantitative microbial risk assessment (QMRA) is a framework prevalently intended for the quantitative estimation of health risks for occupational exposure scenarios (e.g. in WWTPs). However, the quantitative contributions of health-risk-estimate inputted variable parameters remain ambiguous. Therefore, this research aimed to study the disease burden of workers exposed to Staphylococcus aureus bioaerosol during warm and cold periods and to strictly quantify the contributions of the inputted parameters of disease burden by sensitivity analysis based on Monte Carlo simulation. The results showed that the disease health risk burden in the warm period was higher than in the cold period, disease health risk burden in the rotating-disc aeration mode was regularly higher than in the microporous aeration mode. The disease health risk burden of the workers with personal protective equipment (PPE) almost all satisfied the WHO benchmark (≤10E-6 DALYs pppy), and was consistently lower by one or two orders of magnitude than the workers without PPE in both warm and cold periods. Referring to the sensitivity analysis, exposure concentration and aerosol ingestion rate were the most and second predominant factor for the estimated risk in all exposure scenarios, respectively. The sensitivity of the removal fraction by employing PPE ranked third in the contribution to disease health risk burden. In addition, no remarkable differences were revealed in the sensitivity percentage ratio between warm and cold periods. This research can deepen the understanding of the QMRA framework and promote the development of sensitivity analysis, especially under various meteorological conditions (warm and cold periods).
