The main reason for the increase in cross-border mergers and acquisitions in developed and emerging countries is globalization and growing economic interdependence across countries. The state of the economy has a significant impact on whether cross-border mergers and acquisitions are encouraged or discouraged by international strategic capital market changes. This study empirically evaluates the influence of determinants of economic development on the scale effect of Cross Border M&As separately on emerging and developed nations as a research gap. We first separated the small and large scale firms based on companies’ worth and used panel regression to analyze the impact of GDP, employment rate, and market capitalization on cross-border merger & acquisition deals over the period of 2008-2018. Results indicate that GDP and market capitalization have a positive effect on CBM&A, whereas employment rate has a negative effect on CBM&A deals in large-scale firms of both emerging and developed countries. This study results offer the implication for the potential investors and policymakers to strategically analyze the implementation of cross-border mergers & acquisitions.

Stapled transanal rectal resection (STARR) and stapled hemorrhoidopexy (SH) are well-established techniques for treating rectal prolapse and obstructed defecation syndrome (ODS). Occasionally, they can be associated with severe complications. We describe the case of a 59-year-old woman who underwent STARR for ODS and developed a postoperative pelvic hemorrhage. A computed tomography (CT) scan revealed a vast pelvic, retroperitoneal hematoma and free gas in the abdomen. Laparoscopy ruled out any bowel lesions, but identified a hematoma of the pelvis. Flexible sigmoidoscopy showed a small leakage of the rectal suture. The patient was treated conservatively and recovered completely. Surgeons performing STARR and SH must be aware of the risk of this rare, but severe, complication. If the patient is not progressing after a STARR or SH, a CT scan can be indicated to rule out intra-abdominal and pelvic hemorrhage. Laparoscopy is a diagnostic tool and should be associated with intraluminal exploration with flexible sigmoidoscopy.

Purpose: The treatment of acutely obstructing colorectal cancers is still a matter of debate. The prevailing opinion is that an immediate resection should be performed whenever possible. This study sought to determine whether immediate resection is safe and oncologically valid. Methods: We completed a retrospective 2-center cohort study using the medical records of patients admitted for acutely obstructing colorectal cancer under the care of the Colorectal Team, Noble’s Hospital, Isle of Man, and the Emergency Surgery Unit, Umberto I University Hospital, Rome, from March 2013 to May 2017. The primary endpoints were 90-day mortality and morbidity, reoperation rate, and length of stay. The secondary endpoints were status of margins, number of lymph nodes retrieved, and the rate of adequate nodal harvest. Results: Sixty-three patients were retrospectively enrolled in the study. Mortality was associated with age >80 years and Dukes B tumors. The length of hospital stay was shorter in patients who had their resection less than 24 hours from their admission, in those who had laparoscopic resection and in those with distal tumors. The number of lymph nodes retrieved and rate of R0 resections were similar to those reported in elective colorectal surgery and were greater in laparoscopic resections and in patients operated on within 24 hours, respectively. Conclusion: Immediate resection is a safe and reliable option in patients with acutely obstructing colorectal cancer.

A few degrees in temperature above the optimum can cause a considerable yield loss in tomatoes. A research experiment was conducted in which three tomato genotypes of (Solanum lycopersicum Mill.), ‘Suncherry Extra Sweet’ (Suncherry), ‘Walter’, and ‘CLN-2498d’, were evaluated for response to moderate high temperature at the reproductive stage. High temperature reduced the total number of fruits per plant, fruit size, number of seeds per fruit, seed setting, and relative ovule viability. However, high temperature increased proline accumulation and membrane thermo-stability in plant parts of the investigated genotypes. Fruit size and the number of seeds per fruit were reduced in all the genotypes, with the greatest reduction occurring in Suncherry. Similarly, viability of male and female gametes was also reduced in all of the investigated genotypes due to high temperature injury. The reduction in seed setting due to high temperature was greatest in ‘Suncherry’ and ‘Walter’, and least in ‘CLN-2498d’. Likewise, ovule viability was least reduced in ‘CLN-2498d’. The genotypes accumulating higher proline concentrations in reproductive parts and with enhanced membrane thermo-stability under high temperature likewise produced the highest fruit yield, and hence, exhibited high temperature tolerance.

Implementing Firewall to Mitigate YOYO Attack on Multi Master Cluster Nodes Using Fail2Ban
Muhammad Faraz Hyder,Muhammad Umer Farooq,Mustafa Latif,Faizan Razi Khan,Abdul Hameed,Noor Qayyum Khan,M. Ahsan Siddiqui International Journal of Computer ScienceNetwork S 2023 International journal of computer science and netw Vol.23 No.2
Web technology is evolving with the passage of time, from a single node server to high availability and then in the form of Kubernetes. In recent years, the research community have been trying to provide high availability in the form of multi master cluster with a solid election algorithm. This is helpful in increasing the resources in the form of pods inside the worker node. There are new impact of known DDoS attack, which is utilizing the resources at its peak, known as Yoyo attack. It is kind of burst attack that can utilize CPU and memory to its limit and provide legit visitors with a bad experience. In this research, we tried to mitigate the Yoyo attack by introducing a firewall at load-balancer level to prevent the attack from going to the cluster network.
