The algorithm and realization technique of network topology discovery is a very important technical indicator for a network management system’s quality. Based on the knowledge of the network topology discovery theory, the research on ICMP and SNMP programming for Windows, this paper proposes a method of developing the common network topology discovery software which is a conglomerate of ICMP and SNMP protocols so as to monitor a given network and successfully manage it while taking into full advantage of above mentioned protocols.

Partial cholecystectomy is usually performed with the aim of preventing bile duct injury and/or vascular injuries in situations where there is difficulty in performing cholecystectomy. Occasionally, such patients can become symptomatic due to recurrence or persistence of disease in the gallbladder remnant and may require further treatment. A case series of various presentations and follow up of nine patients who had undergone open partial cholecystectomy for symptomatic gallstone disease in the past. Of the 9 patients, 8 were symptomatic, and each of them was found to have a remnant of the gallbladder. Gallbladder remnant was removed in all of them laparoscopicallly, with resolution of the symptoms. One patient remained asymptomatic and is on regular on follow-up. So, although partial cholecystectomy is an accepted, safe option in difficult cases, these patients must be counselled regarding the recurrence of symptoms, and must be kept on follow-up. If symptoms develop, completion of cholecystectomy laparoscopically is a feasible option.

The field experiment was conducted during Rabi season, 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The objective was to study the influence of Biofertilizers and Phosphorous application on growth and yield of field- pea (Pisum sativum L.). The results showed that treatment 9 [Phosphate-solubilizing bacteria (PSB) + Rhizobium along with (70 kg/ha) Phosphorus (P2O5)] recorded significantly higher plant height (54.75 cm), more number of branches/plant (5.15), maximum plant dry weight (8.99 g/plant), maximum pod length (8.05), maximum number of pods/plant (24.97), higher number of grain/pod (7.24), maximum test weight (44.74 g), higher seed yield (16.25 q/ha), higher stover yield (37.11 q/ha) compare to other treatment. The maximum gross return (141133.00 INR/ha), maximum net return (101262.45 INR/ha) and the highest Benefit cost ratio (2.53) was also recorded in treatment 9 as compared to other treatments. Thus the best combination to get maximum growth, yield attributes and economics in field-cultivated Pea (Pisum sativum) was found [PSB + Rhizobium inoculation + 70 kg/ha (P2O5)].
