Abstract
A silica/aminated kaolin (SiO2@AK) composite was prepared by modifying kaolin and loading silica, using intercalation complex method and sol–gel method. Quantitative composites were dispersed in epoxy resin to obtain a silica/aminated kaolin/epoxy resin composite coating (SiO2@AK/EP) on stainless steel. The results showed that the thickness of the dry coating was approximately 110 ± 10 μm, and the surface was flat without evident agglomeration. As the SiO2@AK composite was introduced, the water contact angle increased from 40° to 88°, the average surface roughness of the prepared composite coating was reduced from 10.3 nm to 3.19 nm, and the corrosion current decreased by nearly three orders of magnitude. After the coating was soaked in 3.5 wt% NaCl solution for 30 days, the impedance modulus of the composite coating remained above 2.511 × 109 Ω cm2, reflecting that the introduction of the composite could effectively improve the anticorrosion property of the epoxy resin.

Abstract
The determination of suitable habitats and roadkill hotspots allows for the prioritization of areas of conservation and the identification of road sections that require appropriate planning and development. Understanding the factors that influence the species’ presence and those contributing to its road-related fatalities is crucial. This study demonstrates the use of MaxEnt modeling to map the potential distribution of the striped hyaena (Hyaena hyaena) in Batna province (East Algeria) using occurrence records and a set of environmental variables. The results indicated that the two primary environmental variables that influence the distribution of the species are the shrubland, and the slope with a contribution of 37.5 and 30.2 %, respectively, followed by built-up areas (12 %) and distance to roads (7.2 %). The species may occupy steep terrain with shrubland near anthropized areas. Road collisions represent a threat to the species, with 28 documented casualties from 2010 to 2020 in Batna. The kernel density estimation revealed an important roadkill hotspot along the national roads 3 and 28. This study represents a preliminary step for the use of wildlife ecological niche modeling and road management in Algeria.
Casimir interaction driven by hyperbolic polaritons

Published: May 2024

Abstract
Casimir interaction is an intriguing phenomenon that is induced by electromagnetic quantum fluctuations, which dominates the interaction between microstructures at small separations and is essential for micro- and nano-electromechanical systems (MEMS and NEMS). However, Casimir interaction driven by hyperbolic polaritons remains an unexplored frontier. In this work, we investigate the Casimir interaction between natural hyperbolic material hexagonal boron nitride from the perspective of force distribution with different optical axis orientations for the first time. The attractive Casimir force is remarkably enhanced due to the excitation of volume-confined hyperbolic polaritons (HPs). Furthermore, distinct repulsive contributions to the force are observed due to surface-confined HPs that only exist when the optical axis is in-plane. The HPs are associated with a striking thickness dependence of spectral force properties, suggesting that the discrete volume-confined HPs lead to the attractive-repulsive transition of Casimir force. This work sheds light on the relation between HPs and the vacuum fluctuation-induced force, which could offer new opportunities for the development of the MEMS and NEMS.

Abstract
Globally, enhanced oil recovery (EOR) has become a pressing issue as the demand for crude oil continues to increase. This study investigates the flow and thermal-fluid–solid coupling of crude oil in a rod pump during hot water recovery and obtains the maximum recovery of crude oil in a vertical pipeline through numerical analysis. The pressure gradient in the pump barrel was first developed and deduced based on the ideal gas state equation and Bernoulli’s equation. According to the rheological experiment results, it was proven that the light crude oil conforms to the Newtonian constitutive equation. Subsequently, the momentum equation of crude oil flowing in the pipeline and fluid–solid coupling heat transfer equations were established and solved using the finite difference method. The effects of the thermal recovery temperature T

Introdução: Metástase óssea é a neoplasia maligna mais comum do esqueleto, e a tomada de decisão cirúrgica depende de múltiplos fatores, incluindo as complicações pós-operatórias e a expectativa de vida. A identificação de novos fatores prognósticos pode auxiliar na tomada de decisão.
Objetivo: Analisar em metástases de ossos longos, a incidência de complicações e sobrevida pós-operatórias até 1 ano correlacionando-as com NLR e PLR.
Método: Revisão de 160 prontuários de operados por metástase óssea no esqueleto apendicular. Além de características epidemiológicas, foram determinados os valores de NLR e PLR correlacionando-os com sobrevida e complicações.
Resultado: Mulheres representaram 64,5% com tumor primário na mama em 62,6%; o fêmur proximal foi o mais acometido; sobrevida média foi 13,2 meses e a de 1 ano 34,7%; ressecção tumoral com endoprótese foi mais comum. A taxa de complicação pós-cirúrgicas foi de 10% e o tempo médio para a ocorrência de complicações pós-operatórias foi de 27,9 dias (0-140). Foi encontrada associação da variável neutrófilos com a complicação pós-operatória (p=0,04). A cada 100 unidades a mais de neutrófilos houve aumento de 1% nas chances de complicações pós-cirúrgicas. Valores médios do NLR e PLR foram, respectivamente, 5,3 (0,2-30,7) e 199,7 (32,1-676,7). Os pacientes com NLR ≥ 2 (p<0,001) apresentaram diminuição na sobrevida de 92,3% para 62,5% no 3° mês e de 61,5% para 31,3% em 1 ano. Aqueles com PLR ≥209 (p<0,001) apresentaram diminuição na sobrevida de 69% para 59,3% no 3° mês, e de 40,2% para 25,9% em 1 ano.
Conclusão: Não foi verificada associação positiva entre o NLR e o PLR com complicações pós-operatórias, mas com sobrevida fortemente sim, a partir do 3° mês de pós-operatório.

Novel Resin-Coated Sand Placement Design Guidelines for Controlling Proppant Flowback Post-Slickwater Hydraulic Fracturing Treatments
Authors: Tarek Mohamed , Leung Jada 
Published: May 2024

Summary
Resin-coated sand (RCS) is an effective way for controlling post-stimulation proppant flowback. However, with the shift to slickwater treatment fluids, the “tail-in” placement approach has proved to be less efficient for complete flowback control due to the proppant settling characteristics of using low-viscosity fluids. A new RCS placement approach was developed based on the results of several flowback studies. Trial wells were completed in different US basins with successful results.
Proppant flowback samples were collected during different stages of drillout and production from wells using slickwater fluid systems. Thirty-five wells, completed by thirteen different operators, within the Permian and MidCon basins were evaluated. All wells were completed using multiple proppant mesh sizes. A total of 375 flowback samples were collected during the drillout and production phases. The samples were sieved, and the results were fed into an in-house material balance model to determine the percentages of different mesh sizes in the flowback samples. The conclusions were used as guidelines for a new placement approach implemented in multiple new wells to control proppant flowback.
The flowback samples ranged from predominantly lead proppant to a similar proportion of the pumped mesh sizes. Not one of the 35 wells had flowback samples containing the majority tail-in mesh size. This supports the early sand dune assumption, suggesting that the early proppant forms dunes near the wellbore and late sand settles over the existing proppant beds. The use of late RCS appears to have a minimal effect on preventing flowback of the early proppant within a stage utilizing slickwater fracturing. Therefore, RCS efficiency to control proppant flowback with the tail-in method is reduced when used in such slickwater stimulations. To seal the different proppant beds, the new approach recommends pumping multiple RCS steps within a stage. The first RCS step is recommended within the first 10–20%, the second sequence within the first 40–60% of proppant volume, and the third as a tail-in. The exact percentages and step design were based on the results of flowback samples from neighboring wells. The implementation of this approach in more than 30 wells resulted in superior flowback control compared to offset control wells. In all trials, the proppant flowback completely stopped within 1 to 7 days of starting production.
In this paper, we discuss the drawbacks of the current RCS placement practice while suggesting a new practical approach supported by data. RCS tail-in showed successful flowback control with viscous fracturing fluids and hybrid systems. For slickwater systems, an optimized placement design for RCS throughout the pump schedule provided enhanced flowback control compared to RCS tail-in. Finally, we illustrate the results of field trials in which utilizing the new RCS placement approach successfully reduced flowback.

Published: May 2024

Abstract

Correlated horizontal pleiotropy poses a formidable challenge in Mendelian randomization (MR). Existing methods, relying on sparse pleiotropic variants or zero modal pleiotropy assumption (ZEMPA), may face issues, especially in trait pairs with a high proportion of correlated horizontal pleiotropic variants. We propose an innovative Pleiotropic Clustering model for MR analysis (PCMR) to cluster instrument variables with horizontal or vertical pleiotropic effects. Our simulations showed that PCMR had superior performance in isolating causal effects and detecting correlated horizontal pleiotropy. Moreover, PCMR's causal evaluation extended the ZEMPA and can control false positives in correlated horizontal pleiotropy, even with a high proportion. Applied to real datasets, PCMR detected 15% (8 of 48) trait pairs significant with correlated pleiotropy in common diseases and further enhanced causal inference. Notably, PCMR elucidated why existing methods might overlook the established causal link between smoking behavior and type 2 diabetes. It also confirmed the considered non-causal relationship between high-density lipoprotein and coronary artery disease, and revealed potential non-causal relationships, such as from schizophrenia to major depressive disorder, offering new insights into complex disease mechanisms.

Abstract

The efficiency of the catalyst was investigated in relation to temperature, gas hourly space velocity, the ratio of steam to carbon monoxide, hydrogen sulfide (H2S) loading, and tar concentration. This review paper emphases on the reaction of Fe/Cr catalyst under a high-temperature water gas shift reaction (WGSR) in a pilot plant. The high amount of tar availability in the producer gas(Syngas), has the inverse relation with hydrogen gas production, and lead to deteriorate the quality of syngas or vice-versa. The previous studies stated that increasing the reaction temperature enhance the higher rate of conversion of carbon mono-oxide (CO), clean Hydrogen (H2) gas production, and out gas flow rates. The conversion of CO was not considerably affected by the molar ratio of steam, but it was. When exposed to H2S poisoning, the Fe/Cr catalyst shown strong deactivation resistance, whereas Reactor 2 displayed balanced H2S adsorption and desorption. Additionally, neither catalytic cracking from reformation nor fouling from deposition of tar, was spotted on the catalytic surface. The findings shows that the Fe/Cr catalyst was reliable and deactivation resistant, making it an excellent choice for implement in the high-temperature Water Gas Shifting process. This review article will be advance our knowledge in the area of syngas conversion through biomass gasification process and contribute in the design of reliable and effective catalytic systems for hydrogen gas synthesis process.
