Published: July 2022

An analysis is discussed of the heat and mass transfer for micropolar nanofluid in presence of natural convection from a spherical body with magneto-hydrodynamic (MHD) effects. The constant wall temperature boundary condition is also studied. By employing proper similarity transformations, the governing equations are converted into a set of partial differential equations (PDEs) with the used boundary conditions, which can then be solved numerically via the efficient Keller-box implicit numerical finite difference method. The numerical results of impacts of the controlling parameters on heat transfer physical quantities have been presented, tabular and graphically, by MATLAB symbolic software. Comparisons of the current study results to previously published results show good agreement, indicating that our numerical computations are legitimate and accurate. Increasing nanoparticle volume fraction is observed to depress local skin friction, Nusselt number, and angular velocity while the reverse effects are observed for velocity and temperature.

Published: July 2022

This article treats analytically and numerically to the three dimensional Rössler system. The governing equations of the problem are derived from traditional Lorentz system of fluid mechanics to nonlinear ordinary differential equations (ODEs) for modelling. A semi-analytic solution is developed by using New Iterative Method (NIM) whereas the numerical solution is presented by Runge-Kutta order four (RK4) scheme. A comparative study of the analytical and numerical solutions are made. The results confirm clearly that the two methods coincide closely for both the chaotic and non-chaotic cases of the determined system. This observation would be helpful to apply NIM on nonlinear problems of fluid flow with different fluid parameters in future.

Authors: Ahmad Fuad Abdul Rasid  , Yang Zhang
Published: July 2022

The combustion characteristics of fuel spray can be examined at a basic level by a fuel droplet combustion study. Evaporation processes of a fuel droplet involves few combustion phases mainly heating, boiling and disruptive phase. The transition of phases is found to be caused by two transient combustion process; mainly droplet heating and fuel vapour accumulation. The duration of combustion phases of tested neat fuel droplet in the present work is found to be consistent for each fuel. High volatility fuel is found to have the shortest duration of droplet heating and fuel vapour accumulation. Longer duration of boiling phase provides wider range of measureable burning rate to be done on tested fuel droplet. With precise quantitative measurement method conducted in the present work, high measurement repeatability is assured thus enabling the determination of droplet combustion stability categorization with clear definition throughout the lifetime of evaporating neat fuel droplet. Additionally, this paper summarises the common combustion phases involved during the evaporation of a neat fuel droplet.

The purpose of this study is to see the feasibility of using Computational Fluid Dynamic (CFD) analysis over wind tunnel testing for propeller performance measurement. Computational Fluid Dynamic (CFD) analysis is conducted on APC 6X4E propeller and 9X6E propeller at propeller disc angle, α of 0°, 30°, 60°, and 90° using commercially available software ANSYS FLUENT at advance ratio ranging from 0 to 0.88 and angular velocity ranging from 1000rpm to 8000rpm. CFD analysis was also performed for different advance ratio at different rotational speed of 4000rpm and 8000rpm. Multiple Reference Frame model is used to simulate the rotating propeller in a flowing airstream by constructing a rotating and static domain around the propeller. The non-zero propeller disc angle is achieved by changing the inlet direction of the static domain. The SST k-ω turbulence model is used, and tetrahedral mesh is constructed. The propeller thrust and torque obtained from the CFD simulation is used to calculate the aerodynamic characteristics of the propellers. The thrust coefficient, torque coefficient and propeller efficiency obtained for both propellers follow the trend of the wind tunnel testing. The results obtained from the CFD simulation matches with the results trend obtained by another researcher performing wind tunnel analysis, where the thrust coefficient decreases with increasing advance ratio at propeller disc angle less than 60° and increases with increasing advance ratio at propeller disc angle more than 70°. The error produce for thrust estimation is lower than 12% for both 6x4E and 9x6E propellers. The error for torque and efficiency estimation is between 15-30% and 12% respectively. In conclusion, CFD simulation can predict the aerodynamic characteristics of Low Reynolds Number propeller at different propeller disc angle.

Aside from smart technologies, farm data collection is also important for smart farms including farm environment data collection and farmer survey data collection. With farm data collection, we observe that it is generally proposed to utilize in smart farm systems. However, it can also be released for use in the outside scope of the data collecting organization for an appropriate business reason such as improving the smart farm system, product quality, and customer service. Moreover, we can observe that the farmer survey data collection often includes sensitive data, the private data of farmers. Thus, it could lead to privacy violation issues when it is released. To address these issues in the farmer survey data collection, an anatomization model can protect the users' private data that is available in farmer survey data collection to be proposed. However, it still has disorganized issues and privacy violation issues in the sensitive table that must be addressed. To rid these vulnerabilities of anatomization models, a new privacy preservation model based on data shuffing is proposed in this work. Moreover, the proposed model is evaluated by conducting extensive experiments. The experimental results indicate that the proposed model is more efficient than the anatomization model for the farmer survey data collection. That is, the adversary can have the confidence for re-identifying every sensitive data that is available in farmer survey data collection that is after satisfied by the privacy preservation constraint of the proposed model to be at most 1/l. Furthermore, after the farmer survey data collection satisfies the privacy preservation constraint of the proposed model, it does not have disorganized issues and privacy violation issues from considering the sensitive values.

Icnofósseis no Arenito do Guamá (Pará, Brasil): potenciais registros silurianos
Authors: Martins Taynara Cristina Matos , Soares Joelson Lima , Santos Hudson Pereira
Published: July 2022

Ichnofossils of the Guamá Sandstone (Pará, Brazil): potential Silurian records. The Guamá Sandstone is a unit restricted to the Bragantina Platform in the northeast Pará State. It is characterized by thick layers of well-rounded, well-sorted, medium-grained quartz-sandstone with textural and compositional maturity. In general, the layers exhibit few preserved primary sedimentary structures. The facies association indicates a sandy coastal paleoenvironment comprising the foreshore and shoreface zones. We found in the Guamá Sandstone the ichnospecies Psammichnites isp., cf. Schaubcylindrichnus coronus, Skolithos isp., Skolithos linearis and V-shaped vertical excavations, which commonly compose a mixture of the Cruziana and Skolithos ichnofacies. On the basis of the regular distribution alternating between Skolithos and Psammichnites in the sandstone layers, and the low ichnodiversity and local abundance, we suggest that periodic changes in energy and sedimentation rate occurred. These characteristics of the Guamá Sandstone ichnoassemblage are similar to those of the Ipu (Parnaíba Basin) and Nhamundá (Amazon Basin) formations, although only Skolithos occurs in both units. Keywords: Guamá Sandstone, ichnofacies, foreshore-shoreface, Lower Silurian, paleoenvironment. RESUMO – O Arenito do Guamá é uma unidade restrita à Plataforma Bragantina no nordeste do Estado do Pará. Caracteriza-se por espessas camadas de quartzo-arenito de grão médio, bem arredondadas, bem selecionadas, com maturidade textural e composicional. Em geral, as camadas apresentam poucas estruturas sedimentares primárias preservadas. A associação de fácies indica um paleoambiente costeiro arenoso compreendendo as zonas de foreshore e shoreface. Encontramos no Arenito do Guamá a icnoespécie Psammichnites isp., cf. Schaubcylindrichnus coronus, Skolithos isp., Skolithos linearis e escavações verticais em forma de V, que comumente compõem uma mistura das icnofácies Cruziana e Skolithos. Com base na distribuição regular alternada entre Skolithos e Psammichnitos nas camadas de arenito e a baixa icnodiversidade e abundância local, sugerimos que ocorreram mudanças periódicas na energia e na taxa de sedimentação. Essas características da icnoassembleia do Arenito do Guamá são semelhantes às das formações Ipu (Bacia do Parnaíba) e Nhamundá (Bacia Amazônica), embora apenas Skolithos ocorra em ambas as unidades.

Published: July 2022

Wenzhou has improved its environmental quality because of comprehensive environmental remediation; nevertheless, the semen quality of infertile males remains unclear. This study determined whether better environmental quality improved semen quality in this region. We recorded semen quality data from 22 962 infertile males from January 2014 to November 2019 at the Center for Reproductive Health of The First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China). Patients were predominantly 30–35 years old (33.1%) and workers (82.0%), with high school education or lower (77.6%); more than a half of the patients (52.6%) were Wenzhou household registration; and most patients (77.5%) had abnormal semen quality. Patients who were older than 40 years and workers, and those with Wenzhou household registration, had significantly worse semen quality (all P < 0.05). From 2014 to 2019, progressive sperm motility, total sperm motility, and semen volume showed increasing linear trends in all patients (P = 0.021, 0.030, and 0.005, respectively), yet normal sperm morphology showed a linearly decreasing trend (P = 0.046). Sensitivity analyses for subgroups yielded similar results. In conclusion, the improvement of environmental quality and better function of the accessory glands are associated with progressive sperm motility, total sperm motility, and semen volume. Normal sperm morphology is influenced by occupational exposures and personal lifestyle and does not improve with environmental quality.

Authors: Ren Hongcheng , Ding Mingchao , Huang Xiaoyong , Wang Bin , Chi Guoqing , Shao Changgang , Song Shiyong , Song Wenjie , Shi Ruina
Published: July 2022

Objectives:

The meta-analysis was conducted to systematically assess the efficacy and safety of generic stent-graft/bare-stent combination compared with Fluency stent alone in transjugular intrahepatic portosystemic shunt procedure for refractory variceal bleeding.

Methods:

PubMed, EMBASE, Scopus, Web of Science and the Cochrane Database were searched for relevant studies from January 1990 to September 2020; outcome measures studied were primary patency, hepatic encephalopathy, survival, re-bleeding and portal venous pressure.

Results:

Four studies (1 randomised controlled trial and 3 retrospective studies) with 449 subjects (157 patients in the combined stent group and 292 patients in the covered stent group) were included. No significant difference was observed in the incidence of mortality (hazard ratio [HR] = 1.069, 95% confidence interval [CI] [0.524, 2.178]), hepatic encephalopathy (odds ratio [OR] = 0.860, 95% CI [0.341, 2.169], P = 0.750) and re-bleeding (OR = 1.049, 95% CI [0.226, 4.881], P = 0.951). Compared with Fluency stent alone, combination therapy was associated with moderate decrease in outcomes on the post-operative portal venous pressure (standard mean difference [SMD] −0.210, 95% CI [−0.418, −0.001], P = 0.049) and was not associated with significant decrease in outcomes on the pre-operative portal venous pressure (SMD − 0.129, 95% CI [−0.336, 0.078], P = 0.223). The primary patency was significantly lower in the Fluency/bare-stent combination group (HR = 0.473, 95% CI [0.288, 0.776]).

Conclusions:

Generic stent-graft/bare-stent combination therapy was associated with significantly lower primary patency compared to Fluency stent alone.
Endoscopic ultrasound-guided drainage to abdominal abscess
Authors: Liu Sifan , Tian Zibin , Jiang Yueping , Mao Tao , Ding Xueli , Jing Xue
Published: July 2022

Background:

Ultrasound (US)- or computed tomography-guided drainage for abdominal abscess is currently the first-line options for drainage, but both options have disadvantages. Patients without adequate windows for drainage mostly undergo surgical drainage. However, surgical drainage is invasive and expensive. Endoscopic US (EUS)-guided drainage is a minimally invasive alternative for abdominal abscess, but there is less consensus on its efficacy, safety and complications. This meta-analysis aims to evaluate EUS-guided drainage for abdominal abscess.

Materials and Methods:

We retrieved relevant papers on EUS-guided drainage for abdominal abscess from the PubMed, Cochrane Library, Web of Science and EMBASE databases. Each paper was reviewed, and data were extracted. We used R software version 3.6.3 to perform the meta-analysis. Fixed effects models were used for merging data.

Results:

A total of 11 papers met the inclusion criteria, with a total sample population of 264 patients. The meta-analysis showed that the pooled clinical success rate was 90% (95% confidence interval [CI], 0.85–0.95), the technical success rate was 99% (95% CI, 0.97–1.00) and the recurrence rate was 1% (95% CI, 0.00–0.03). Three studies reported the complications, including perforation, bleeding and stent migration; none of the other eight studies reported complications. There were no significant differences between subgroups. There was no publication bias in either the clinical or the technical success rates.

Conclusions:

This meta-analysis showed that EUS-guided drainage for abdominal abscess was effective and safe, with an excellent technical success rate. In addition, EUS-guided drainage could be used for abscesses with complex anatomy. Nevertheless, complications and stent type should be considered.
Single-port laparoscopic appendectomy for perforated appendicitis using ArtiSential® wristed articulated instrument
Authors: Bae Sung Uk , Jeong Woon Kyung , Baek Seong Kyu
Published: July 2022

Single-port laparoscopic appendectomy (SPLA) was firstly introduced in 1998 and has been suggested potential advantages including better cosmetic outcome, less post-operative pain and avoidance of possible haemorrhagic complications from injuring epigastric vessels. However, single-port laparoscopic approach using conventional straight instruments may lead to internal and external conflicts and ergonomic discomfort, and new laparoscopic articulating instruments were developed to overcome these limitations of straight instruments. The ArtiSential® (LIVSMED Inc., Republic of Korea) is an 8-mm diameter pistol-handle instrument that has complete articulating function like human wrist and intuitive controllability. We present a technical report of SPLA for perforated appendicitis using ArtiSential® wristed articulated instrument. A 78-year-old female with a body mass index of 23.5 was referred to our emergency room with right lower quadrant abdominal pain. Abdominal computed tomography scan showed a distended tubular structure in the right lower quadrant (1.2 cm in diameter) with periappendiceal fluid collection. The patient’s clinical presentation was highly indicative of perforated acute appendicitis. We performed SPLA with ArtiSential® grasper with the left hand, and this instrument helped us to allow greater manoeuvrability and dexterity with double triangulation technique. The total operation time was 40 min, and the patient was discharged without complications on the 1st day after surgery.
Laparoscopic approach for malignant retrorectal tumour: Better vision and lesser morbidity
Authors: Shanmugam Subbiah , Pravenkumar R. R.
Published: July 2022

The retrorectal tumours are removed by open approaches according to the type, location and size of the lesion. Malignant tumours are mostly operated by open approach owing to the fear of spillage and inability to obtain safe oncological margin. We present our recent experience of laparoscopy for a malignant retrorectal tumour. An 11 cm pre-sacral mass causing erosion of sacrum was operated with a combined approach. Transsacral approach followed laparoscopic mobilisation with the patient in prone jackknife position. Wide excision with sacrectomy was done with adequate margin. Post-operative histopathology showed dedifferentiated chordoma for which adjuvant radiotherapy was given. Laparoscopic approach provides a feasible and oncological safe alternative to the conventional approaches, especially in malignant tumour with advantages of better visualisation, minimal operative morbidity, lesser post-operative pain and shorter hospital stay. However, the surgical approach should be tailored to each patient according to patient factors, tumour characteristics and surgeon’s expertise.
Prognosis of laparoscopic surgery for colorectal cancer in middle-aged patients
Authors: Bao Feng , Wu Li-Rong , Deng Zhi-Gang , Xiang Chun-Hua , Shang Jian-Ying
Published: July 2022

Background:

The prognosis of middle-aged patients with colorectal cancer (CRC) treated by laparoscopic resection (LR) is unclear. This study aimed to evaluate the survival outcomes of LR compared with open resection (OR) for middle-aged patients with CRC.

Patients and Methods:

This retrospective cohort study used the data from a database of all consecutive colorectal resections performed between January 2009 and December 2017. Propensity score matching (PSM) was performed to handle the selection bias based on age, gender, body mass index, tumour location, AJCC stage and admission year. Univariate and multivariate COX regression model was used to identify risk factors of overall survival (OS) and disease-free survival (DFS).

Results:

After PSM, 154 patients were included in each group. Compared with the OR group in the total cohort, there were better survival outcomes in the LR group for 5-year OS and 5-year DFS (both P < 0.001). These differences were observed for Stage II and III diseases and for all CRC, irrespective of location. The multivariate analysis showed that tumour ≥5 cm (hazard ratio [HR] = 1.750, 95% confidence interval [CI]: 1.026–2.986, P = 0.040), Stage III (HR = 14.092, 95% CI: 1.894–104.848, P = 0.010) and LR (HR = 0.300, 95% CI: 0.160–0.560, P < 0.001) were independently associated with OS. Pre-operative carcinoembryonic antigen ≥5 ng/ml (HR = 3.954, 95% CI: 1.363–11.473, P = 0.011), Stage III (HR = 6.206, 95% CI: 1.470–26.200, P = 0.013) and LR (HR = 0.341, 95% CI: 0.178–0.653, P = 0.001) were independently associated with DFS.

Conclusions:

In middle-aged patients with CRC, LR achieves better survival than OR. Complications are similar, except for less blood loss and shorter post-surgical hospital stay with LR.
Moduli spaces on the Kuznetsov component of Fano threefolds of index 2
Authors: Altavilla Matteo , Petkovic Marin , Rota Franco
Published: July 2022

General hyperplane sections of a Fano threefold $Y$ of index 2 and Picard rank 1 are del Pezzo surfaces, and their Picard group is related to a root system. To the corresponding roots, we associate objects in the Kuznetsov component of $Y$ and investigate their moduli spaces, using the stability condition constructed by Bayer, Lahoz, Macr\`i, and Stellari, and the Abel--Jacobi map. We identify a subvariety of the moduli space isomorphic to $Y$ itself, and as an application we prove a (refined) categorical Torelli theorem for general quartic double solids.
