Umbilical endometriosis along with peritoneal endometriosis: a case report
Incidence of endometriosis is around 10 to 15% in women of reproductive age group. Umbilical endometriosis is a very rare entity. Extra genital endometriosis accounts to 3% of endometriosis. Incidence of umbilical endometriosis is 0.5%-4% of extra genital endometriosis. 30 years old multi gravida was referred to our hospital with c/o periodic bleeding from the umbilicus for the past 3 months. She was also having dysmenorrhoea for about 3 months. On examination, patient had a small bluish nodule in the umbilicus around 1.5x1.2 cm in size. Clinically there was suspicion of pelvic endometriosis as the uterus was retroverted and fixed. CT abdomen showed a small hypo-echoeic area in the umbilicus and uterus was adenomyotic with normal ovaries. Patient was given the option of laparoscopy and excision of umbilicus, as there was suspicion of peritoneal endometriosis and the patient also insisted upon laparoscopic sterilization. Laparoscopy showed early peritoneal endometriosis with pelvic adhesions and the same adhesiolysis was done along with cauterization of endometriosis. Sterilization was also done as per the patient’s request. Umbilical excision and layer closure was done. Umbilical endometriosis is a rare entity. This patient had associated early pelvic endometriosis. Umbilical endometriosis could be secondary to the lympho vascular spread from the pelvic endometriosis or primary umbilical endometriosis. History, clinical and imaging were pointing towards umbilical endometriosis. Surgical excision of umbilical endometriosis and cauterisation of early pelvic endometriosis were done. Patient needs follow up. Umbilical endometriosis may be primary or secondary which needs total excision and follow up
Enhancement of cloud performance metrics using dynamic degree memory balanced allocation algorithm
In cloud computing, load balancing among the resources is required to schedule a task, which is a key challenge. This paper proposes a dynamic degree memory balanced allocation (D2MBA) algorithm which allocate virtual machine (VM) to a best suitable host, based on availability of random-access memory (RAM) and microprocessor without interlocked pipelined stages (MIPS) of host and allocate task to a best suitable VM by considering balanced condition of VM. The proposed D2MBA algorithm has been simulated using a simulation tool CloudSim by varying number of tasks and keeping number of VMs constant and vice versa. The D2MBA algorithm is compared with the other load balancing algorithms viz. Round Robin (RR) and dynamic degree balance with central processing unit (CPU) based (D2B_CPU based) with respect to performance parameters such as execution cost, degree of imbalance and makespan time. It is found that the D2MBA algorithm has a large reduction in the performance parameters such as execution cost, degree of imbalance and makespan time as compared with RR and D2B CPU based algorithm
In-depth analysis of dynamic degree load balancing technique in public cloud for heterogeneous cloudlets
Load balancing is one of the challenges of the distributed computing worldview. With the enormous development in clients and their interest for different administrations on the distributed computing stage, compelling or productive asset usage in the cloud climate has turned into an urgent concern. Load balancing is critical to keeping cloud computing running smoothly. This study examines the research using four scheduling algorithms: dynamic degree balance CPU based (D2B_CPU), dynamic degree balanced membership based (D2B_Membership), dynamic degree memory balanced allocation (D2MBA) and hybrid dynamic degree balance (HDDB) algorithm. Central processing unit (CPU) utilisation, bandwidth utilisation, and memory utilisation are used as performance measures to verify the performance of these algorithms. The CloudSim simulation programme was used to simulate these algorithms. The primary goal of this work is to aid in the future construction of new algorithms by researching the behaviour of various existing algorithms
Multi-label learning by extended multi-tier stacked ensemble method with label correlated feature subset augmentation
Classification is one of the basic and most important operations that can be used in data science and machine learning applications. Multi-label classification is an extension of the multi-class problem where a set of class labels are associated with a particular instance at a time. In a multiclass problem, a single class label is associated with an instance at a time. However, there are many different stacked ensemble methods that have been proposed and because of the complexity associated with the multi-label problems, there is still a lot of scope for improving the prediction accuracy. In this paper, we are proposing the novel extended multi-tier stacked ensemble (EMSTE) method with label correlationby feature subset selection technique and then augmenting those feature subsets while constructing the intermediate dataset for improving the prediction accuracy in the generalization phase of the stacking. The performance effect of the proposed method has been compared with existing methods and showed that our proposed method outperforms the other methods
Development and evaluation of RTE (Ready To Eat) extruded snack using egg albumin powder and cheese powder
Extruded snacks were prepared from flour blends made with corn flour, rice flour and egg albumin powder / Cheese powder in a proportion of 35-50 : 35-50 : 5-30 respectively, and moisture was adjusted to 17-20. Different formulations were extruded at 80 ± 5℃ (heater I) and 75-105℃ (heater II) temperature, 300-350 r m-1 screw speed, 100 ± 10℃ die temperature, 3 mm exit diameter of circular die and 15 ± 2 kg h-1 feed rate. Sensory acceptability, physical parameters and nutrient analysis along with storage stability of the products was conducted. The protein content of the RTE extruded snack improved by 20% to 50% in experimental samples prepared using egg albumin powder and cheese powder. The physical parameters showed improved expansion ratio compared to control samples with good sensory properties. Storage studies showed increase in moisture content in the extrudates on storage which can be improved using packaging materials with better barrier properties. The use of egg albumin powder / cheese powder in an RTE snack product could make a great contribution to food security in developing countries.

Field Screening of Black Gram Genotypes for Resistance against the Spotted Pod Borer, Maruca vitrata (Fabricius) under Southern Telangana Conditions, India
Black gram (Vigna mungo L. Hepper) is India\u27s third most important pulse crop. Throughout its growth, the crop is vulnerable to various insect pests from sowing to harvest and during post-harvest. In Telangana, farmers are experiencing significant yield losses due to lepidopteran pests that feed on flowers and pods, particularly the spotted pod borer. Larvae feed continuously within webbed masses of flowers and pods. The present investigation was conducted during Rabi, 2023 at the Student Farm, College of Agriculture, Rajendranagar, Hyderabad, to identify resistant black gram genotypes against spotted pod borer. A total of 28 black gram genotypes were screened under field conditions for spotted pod borer resistance, resulting in the identification of two resistant genotypes with a rating of 3, ten moderately resistant with a rating of 4, ten moderately susceptible with a rating of 7 and five susceptible with a rating of 8, based on a pest resistance per cent. The results also revealed that the genotypes GBG-1 and PU-31 showed the lowest mean number of larvae per plant (2.21 and 2.31, respectively) and lowest pod damage per cent (3.98 and 4.07%, respectively) and were categorized as resistant (R)

Enhancing finger millet yield and grain quality through stale seedbed and live mulch strategies
Finger millet grains are highly nutritious and contain higher amount of mineral nutrients compared to other cereals and millets. However, weed infestation remains a major biological constraint that significantly reduces its productivity. To address this challenge, field experiments were conducted during the Rabi and summer seasons of 2022–23 to assess the impact of non-chemical weed management practices on the yield and grain quality of finger millet. The experiments were laid out in Randomized Block Design (RBD) with three replications, incorporating two factors: seedbed preparation methods (normal seedbed [NSB], stale seedbed [SSB] with light raking and SSB with flaming) and live mulching treatments (control and three different leguminous live mulches). Live mulches were incorporated into the soil at 40 days after sowing (DAS) using a wheel hoe weeder. Pooled data indicated a significant interaction between seedbed and live mulching treatments. The highest grain yield (885 kg ha-1) was recorded under SSB with light raking combined with cowpea live mulching. This combination also enhanced grain phosphorus (0.180 % in Rabi, 0.165 % in summer) and protein content (14.50 % in Rabi, 14.23 % in summer). Meanwhile, SSB with flaming combined with green gram live mulch significantly increased grain potassium levels (1.49 % in Rabi, 1.46 % in summer), while the highest starch content was found with SSB + flaming and cowpea mulch (74.03 % in Rabi, 82.17 % in summer). These results highlight the effectiveness of integrating stale seedbed preparation with live mulching to improve both the productivity and nutritional quality of finger millet under non-chemical weed management systems
