Background and Aim: The incidence of incisional hernias has been reported to be around 15%. In the present scenario, a wide array of surgical procedures are available for their better management. In this study, we intend to share our experience with one novel technique, “Hybrid IPOm (Intraperitoneal onlay meshplasty)” as a management option for a selected cohort of patients. methods: This prospective study was undertaken during January 2019 to July 2023 at King Abdullah medical city, makkah. A total of 51 cases were selected for Hybrid IPOm repair as per inclusion criteria;medium sized (4 - 10 cm) hernia defects;uncomplicated hernias;age more than 18 years. The follow-up period of the patients varied from 6 months to 4 years. The operation commenced with open hernia dissection, mesh deployment into abdomen, defect closure and then conversion to laparoscopy for the posterior mesh placement. Results: A total of 51 cases were repaired successfully with this technique. 48 out of 51 cases were incisional hernias secondary to some primary procedure done either for hernias itself or some other intra-abdominal pathology. The three cases were primary hernias falling in medium to large category with unaesthetic overlying skin. The age range was 19 to 72 years. The mean (range) operative time was 135 (90 - 240) min, and the average blood loss was 70 ml. The mean (range) hospital stay was 3 (2 - 11) days. All patients returned to routine work within 2 - 3 weeks of surgery. The median follow-up was 15 (6 - 48) months. Of the 51 cases, 3 patients developed seroma (managed conservatively), 1 patient developed a large hematoma (needed evacuation), and 1 patient developed superficial wound infection (managed with antibiotics). Two patients had recurrences;one patient had previously failed multiple repairs, and the other developed a postoperative hematoma. None of our patients had an iatrogenic bowel injury. Conclusion: Hybrid IPOm technique is a safe, feasible and easily reproducibl

[目的]了解豇豆花瓣表面润湿性能,提高防治药剂精准施药水平。[方法]采用座滴法测定豇豆花的旗瓣内外侧、翼瓣内外侧和龙骨瓣外侧等5个花瓣表面的接触角,采用朱定一(ZDY)法计算其固体表面自由能,进一步测定了25%噻虫嗪水分散粒剂(WG)稀释液及其添加PSPE助剂后药液在花瓣表面的静态和动态接触角,并采用最大泡压法测定噻虫嗪药液及其添加助剂后药液动态表面张力(DST)。[结果]豇豆5个花瓣表面除了旗瓣外侧表面为亲水型,其他4个花瓣表面均为疏水型(接触角θ大于90°),花瓣表面自由能值在23.15~60.31 mJ/m^(2)之间。25%噻虫嗪WG的250、125 mg/L处理药液在豇豆花瓣表面上总体润湿性差,添加PSPE助剂后,药液对豇豆花瓣表面接触角在30 s时降至20°以下,静态接触角降低75%以上,显著低于未添加助剂的药液。添加助剂的药液在5个豇豆花瓣表面的接触角下降趋势相似,在0~10 s内快速下降而后平稳降低,DST在50~500 ms内快速降低,在10 s时降至23.15 mN/m及以下。药液添加助剂浓度由0.05%提高至0.1%,DST下降更快,5 s后在旗瓣内侧、翼瓣内外侧和龙骨瓣外侧表面接触角均低于10°,药液DST快速下降区时间提前。[结论]添加聚醚有机硅PSPE助剂可使25%噻虫嗪WG喷雾药液在豇豆花瓣表面快速润湿铺展。

With the rapid development of cyberspace and smart home technology, human life is changing to a new virtual dimension with several promises for improving its quality. moreover, the heterogeneous, dynamic, and internet-connected nature of smart homes brings many privacy and security difficulties. Unauthorized access to the smart home system is one of the most harmful actions and can cause several trust problems and relationship conflicts between family members and invoke home privacy issues. Access control is one of the best solutions for handling this threat, and it has been used to protect smart homes and other Internet of Things domains for many years. This survey reviews existing access control schemes for smart homes, which concern the essential authorization requirements and challenges that need to be considered while designing an authorization framework for smart homes. Furthermore, we note the most critical challenges that other access control solutions neglect for smart homes.

This paper deals with an experimental, theoretical and numerical study of a turbulent flow with separated boundary layers between a rotor and a stator. The system is not subjected to any superimposed radial flow. The periphery of the cavity is opened to the atmosphere so that the solid body rotation for infinite discs is not always observed. Emphasis was placed on develop- ment of an asymptotic approach and a step-by-step method to compute the radial distribution of the core swirl ratio and the static pressure on the stator side. The theory also includes the radial and axial velocities in the core region. The numerical simulation has been conducted with the commercial CFD code Fluent 6.1. The k- SST turbulence model is used, with the assumption of 2D-axisymmetric and steady flow. CFD validations have been performed by comparison of the numerical results with the corresponding theoretical results. Numerical and experimental results are in good agreement with analytical solutions.

The surface topography of noble metal particles is a significant factor in tailoring surface-enhanced Raman scattering （SERS） properties. Here, we present a simple fabrication route to hexagonally arranged arrays of surface-roughened urchin- like Ag hemispheres （Ag-HSs） decorated with Ag nanoparticles （Ag-NPs） for highly active and reproducible SERS substrates. The urchin-like Ag-HS arrays are achieved by sputtering Ag onto the top surface of a highly ordered porous anodic aluminum oxide （AAO） template to form ordered arrays of smooth Ag-HSs and then by electrodepositing Ag-NPs onto the surface of each Ag-HS. Owing to the ordered arrangement of the Ag-HSs and the improved surface roughness, the urchin-like hierarchical Ag-HS arrays can provide sufficient and uniform ＂hot spots＂ for reproducible and highly active SERS effects. Using the urchin-like Ag-HS arrays as SERS substrates, 10-7 m dibutyl phthalate （a member of plasticizers family） and 1.5 × 10-5 m PCB-77 （one congener of polychlorinated biphenyl, a notorious class of pollutants） are identified, showing promising potential for these substrates in the rapid recognition of organic pollutants.
