Published: November 2024

Crude oil distillation (CDU) is a crucial unit in refinery plants for producing various crude oil cuts, such as naphtha, kerosene, light gas oil, heavy gas oil, and Atm residue. This study used ASPEN HYSYS V11 software to examine the parameters that affect CDU efficiency in South Refinery Company /Iraq-Mishriff crude oil, like temperature, pressure, and flow rate. Optimization of these variables was applied to identify suiTable values for separation products. The study reveals that the increased mass flow rate of crude oil to CDU increases the flow rates of naphtha, kerosene, and HGO. The study also examines the impact of the temperature of feed crude oil on CDU. Results show that the volume flow of products increases with increased temperature except the naphtha values decrease. The simulated liquid volume flow for the Naphtha value was 57.96 m3/h higher than the original data of 50.7 m3/h and the kerosene value was 49.24 m3/h lower than the plant value of 51.5 m3/h. The effect temperature was also studied, the volume of liquid flow is directly proportional to the increase in temperature of the crude oil, whether it was a TBP or ASTM blend. The refinery and simulated values were compared, and a satisfactory agreement between the simulated and real results was observed, with some clear differences in the LGO values. The cause of this difference may be the result of the changes during the laboratory tests, or Sampling strategies may affect the accuracy of ASTM D86 tests and laboratory results. Optimization is crucial for optimal operating conditions for efficient product production. Most plant data align with optimized conditions, except for some. For instance, the perfect temperature of crude oil in the distillation unit is 382 oC instead of 375 oC, and the better mass flow of LGO steam is 1431 kg/h rather than 1100 kg/h
Analysis and selection of slurry composition, resistant to dynamic loads, in order to improve the quality of fastening the near wellbore zone in unstable formations
Authors: Novruzova Sudaba , Aliyev Inglab , Ahmad Fariz 
Published: November 2024

The practice of cementing the bottomhole zone of wells in unstable formations shows that cement stone, designed to ensure rock stability, is the weakest link and can easily be destroyed under the influence of various loads. Such loads include perforation of the production string, hydraulic fracturing and other technological operations. The main factor contributing to the destruction of cement stone under dynamic loading is its low deformation properties. Repeated or cyclic loads cause fatigue phenomena in cement stone and lead to the formation and development of fractures in it. However, currently used cementing materials based on Portland cement have poor resistance to impact loads and low tensile strength. Therefore, the need to create an effective barrier with sand when cementing the bottomhole zone by developing reliable cementing compositions resistant to dynamic loads is relevant task. Therefore, task of current interest is the need to create an effective sand barrier when cementing the bottomhole zone by developing reliable cement compositions that are resistant to dynamic loads.
One of the promising ways to protect the integrity of cement stone during perforation and hydraulic fracturing is to control the physical and mechanical properties of the cement material by adding various types of chemical reagents into cement compositions. The object of the study is cement stone created in the bottomhole zone of sand-producing wells. Here, a scientifically applied problem, the purpose of which was to increase the plastic properties of the cement slurry and increase resistance to deformations, as well as crack resistance was solved. In this regard, it is necessary to study the influence of various additives on the processes of formation of the structure, as well as other rheological and physical-mechanical properties of the cement slurry and stone. The studies carried out are based on the use of local raw materials and residual materials, as well as the correct determination of perforation time accordingly. In order to solve the problem, experiments in laboratory conditions were carried out. A special plugging cement of G-I-100 grade was used in the experiments. To achieve indicators aimed at improving the plastic properties of the prepared cement stone, plasticizers were used.
The use of the Bentomix 1275 plasticizer in wells preserves the natural structure and filtration properties of the formation, which helps to increase oil production volumes. The Bentomix 1275 plasticizer accelerates the timing of putting wells into operation, and there is an increase in total and current production due to improved formation opening.
The effect is due to the increase in the length of perforation channels in the formation due to the absence of fragments of cement stone, as well as an increase in the efficiency of fastening due to an increase in the structure in oriented zones

Published: November 2024

The aim of this study is to determine the characteristics of PANI/ZnO nanocomposites and its sensitivity to methanol, ethanol, and butanol at low concentrations. The synthesis process was oxidation polymerization followed by wet mixing. FTIR was used to identify the PANI/ZnO NCs phase, XRD to investigate the PANI/ZnO NCs structure, EDX to analyze the elements, and SEM to examine the sample microstructure. Sensitivity is determined using the four-point probe (FPP) method, which measures the change in resistance of PANI/ZnO NCs when exposed to alcohol vapor. The FTIR analysis results confirmed the presence of C=C stretch (Quinoid) and C-C stretch (Benzenoid) bonds from PANI, as well as ZnO's unique peaks, notably Zn-O-Zn. The PANI/ZnO nanocomposite's diffraction peak at 2θ=21.22° showed amorphous semicrystalline PANI, whereas the peak at 31.75° suggested crystalline ZnO. Elemental analysis revealed that the sample contained N and C elements from PANI, as well as Zn elements from ZnO. Microstructure investigations revealed that the PANI/ZnO NCs had an ovoidal form with an average diameter of 293 nm. PANI/ZnO NCs have been shown to detect methanol, ethanol, and butanol vapors at low levels. When exposed to butanol vapors, the PANI/ZnO NCs exhibit a greater resistance change response than when exposed to other alcohol vapor. Although PANI/ZnO NCs have a higher sensitivity for detecting butanol vapor, they respond faster to methanol vapor than the other two alcohols. The response time was 40 seconds when PANI/ZnO NCs were subjected to methanol vapor at a concentration of 5 ppm, followed by a 20-second recovery period. Furthermore, PANI/ZnO NCs become more sensitive as alcohol vapor concentration increases
Impact of cutting fluid velocity and flow rate on wear and surface roughness in turning operations
Authors: Al-Saraireh Falah Mustafa 
Published: November 2024

This study presents the effects of cutting fluid velocity and flow rate on the wear of high-speed steel cutting tools and the surface roughness of machined AISI D2 steel samples. Employing a 2.2 Kw lathe machine, turning operations were performed. A 10 % concentration emulsion or mixture was produced by mixing Blasocut 2000 universal concentrate with water. Tool wear was calculated by measuring the percentage weight loss, whereas, the surface's roughness was measured using a profile meter. To create an emulsion or mixture with a 10 % concentration, Blasocut 2000 universal concentrate was mixed with water. A stopwatch and a measuring beaker were used to measure the cutting fluid's flow rate. Surface roughness could be decreased most successfully with a high flow rate of cutting fluid, whereas wear could be reduced most effectively with a medium flow rate. A deeper cut results in a larger wear surface area on the flanks.
For surface roughness, the depth of cut proved to be most effective. which was 1.2 µm at 31 ml/sec cutting fluid flow rate while cutting speed has the most effect on tool wear. While wear could be reduced most effectively at a medium flow rate of Q=43 ml/sec, the surface roughness Ra=0.64 µm could be reduced most effectively at a high cutting fluid flow rate of Q=85 ml/sec. The best surface roughness characteristics were found in the confirmation experiment at a medium cutting speed=100 m/min, a low fluid flow rate of Q=21 ml/sec with a high cutting fluid velocity Vf=100 m/min, a low depth of cut of 0.5 mm, and a high cutting fluid flow rate. Moderate feed rate, medium cutting speed, medium cutting depth, and medium cutting flow rate were determined to be the best cutting parameters

Ultrasound-Guided High-Intensity Focused Ultrasound Combined With PD-1 Blockade in Patients With Liver Metastases From Lung Cancer: Protocol for a Single-Arm Phase 2 Trial
Authors: Hu Chao , Fu Qiang , Gao Fei Fei , Zeng Jian , Xiao Wei , Li Hui , Peng Li , Huang Xi , Yang Li , Chen Wen Zhi , Jiang Ming Yan 
Published: November 2024

Background
While immunotherapy has revolutionized oncological management, its efficacy in lung cancer patients with liver metastases remains limited, potentially due to the unique immunosuppressive microenvironment of the liver. Local liver treatment has been shown to enhance the immunotherapy response, and high-intensity focused ultrasound (HIFU), a minimally invasive local treatment, has demonstrated promising results in combination with immunotherapy. However, clinical data regarding HIFU in lung cancer with liver metastases are limited.

Objective
We designed the HILL (Ultrasound-Guided High-Intensity Focused Ultrasound Combined With PD-1 Blockade in Patients With Liver Metastases From Lung Cancer) study to investigate the effectiveness and safety of HIFU in combination with immunotherapy for lung cancer with liver metastases.

Methods
The HILL study is a single-armed, single-center, phase 2 clinical trial that will enroll 30 patients with lung cancer and liver metastases. The treatment regimen involves administering HIFU to liver metastases 1 week before the first dose of a programmed cell death protein (PD)–1 blockade, which is then administered every 3 weeks. The primary aim is to determine the overall response rate based on immune-related response criteria. Secondary aims include safety, progression-free survival, overall response, overall survival, and quality of life. Exploratory studies will also be conducted using whole blood, plasma, archival cancer tissue, and tumor biopsies during progression or relapse to identify potential biomarkers.

Results
The study was funded on March 14, 2022, and received ethical approval on April 27, 2022. Clinical trial registration was completed by June 10, 2022, with participant recruitment beginning on July 10, 2022. Data collection commenced on July 14, 2022, with the enrollment of the first patient. By April 2024, 6 participants had been recruited. The results are expected to be published in December 2026.

Conclusions
This study seeks to improve treatment outcomes for lung cancer patients with liver metastases by combining HIFU and PD-1 inhibition. The study also aims to identify potential biomarkers through exploratory research that can aid in selecting patients for optimized outcomes in the future.

Eco-Evolutionary Drivers of Vibrio parahaemolyticus Sequence Type 3 Expansion: Retrospective Machine Learning Approach
Authors: Campbell Amy Marie , Hauton Chris , van Aerle Ronny , Martinez-Urtaza Jaime 
Published: November 2024

Background
Environmentally sensitive pathogens exhibit ecological and evolutionary responses to climate change that result in the emergence and global expansion of well-adapted variants. It is imperative to understand the mechanisms that facilitate pathogen emergence and expansion, as well as the drivers behind the mechanisms, to understand and prepare for future pandemic expansions.

Objective
The unique, rapid, global expansion of a clonal complex of Vibrio parahaemolyticus (a marine bacterium causing gastroenteritis infections) named Vibrio parahaemolyticus sequence type 3 (VpST3) provides an opportunity to explore the eco-evolutionary drivers of pathogen expansion.

Methods
The global expansion of VpST3 was reconstructed using VpST3 genomes, which were then classified into metrics characterizing the stages of this expansion process, indicative of the stages of emergence and establishment. We used machine learning, specifically a random forest classifier, to test a range of ecological and evolutionary drivers for their potential in predicting VpST3 expansion dynamics.

Results
We identified a range of evolutionary features, including mutations in the core genome and accessory gene presence, associated with expansion dynamics. A range of random forest classifier approaches were tested to predict expansion classification metrics for each genome. The highest predictive accuracies (ranging from 0.722 to 0.967) were achieved for models using a combined eco-evolutionary approach. While population structure and the difference between introduced and established isolates could be predicted to a high accuracy, our model reported multiple false positives when predicting the success of an introduced isolate, suggesting potential limiting factors not represented in our eco-evolutionary features. Regional models produced for 2 countries reporting the most VpST3 genomes had varying success, reflecting the impacts of class imbalance.

Conclusions
These novel insights into evolutionary features and ecological conditions related to the stages of VpST3 expansion showcase the potential of machine learning models using genomic data and will contribute to the future understanding of the eco-evolutionary pathways of climate-sensitive pathogens.

Published: November 2024

O presente ensaio tem o objetivo de analisar os efeitos desastrosos do capitalismo à frente da figura do trabalhador e do tipo de sociedade que vêm sendo constituídos ao longo dos séculos da humanidade, através da perspectiva, principalmente, de Byun-Chul Han, bem como da visão de Baudrillard, Krenak, Gadamer e outros. Visando ainda, fazer uma breve contextualização sobre a presença do capital como mola de exploração e de alienação, buscou-se verificar quais são as melhores estratégias para amenizar os diversos problemas de ordem física e emocional, que afetam o mercado de trabalho. Para tanto, o tipo de pesquisa adotada para este estudo foi a pesquisa bibliográfica, na qual consiste numa revisão de literatura, analisando os pontos principais da obra A sociedade do cansaço. Assim, conclui-se que o estudo chegou no âmago da necessidade humana, visto que o ser humano não é como uma máquina de trabalho projetada e controlada para o trabalho e, sim uma subjetividade carente dos afetos que potencializem o seu ser.

Published: November 2024

The transition from partial to total edentulism is a delicate situation for certain patients that involves the practitioner in the management process. The immediate complete prosthesis is therefore an effective solution capable of removing the constraint of appearing totally edentulous by delivering a prosthesis on the day of extraction of the remaining teeth. A partially edentulous patient consulted us with the typical indication for this immediate prosthesis with four remaining maxillary incisors and a major aesthetic concern. The prosthetic production chain is particular concerning firstly the presence of a bilateral terminal edentulism, the confection of the individual impression tray, the orientation of the anterior occlusion plane while anterior teeth remaining on the arch, the fitting of the prosthetic anterior teeth following the working model rectification as well as the surgical phase on the day of denture insertion. Surgical guide would be very useful when bone regularization is imperative. The post-prosthetic follow-up phase is important in order to optimize tissue integration of the prosthesis, while taking into consideration the rebasing that is often unavoidable after a few months. Blood problems, a protracted healing process, significant bone loss, mental illness, or emotional problems contraindicate this type of prosthesis. The dentist and the laboratory technician are invited to master the clinical and laboratory stages of this prosthesis in order to appropriate the result aesthetically and functionally.
