Small cells deliver cost-effective capacity and coverage enhancement in a cellular network. In this work, we present the interplay of two technologies, namely Wi-Fi offloading and small-cell cooperation that help in achieving this goal. Both these technologies are also being considered for 5G and B5G (Beyond 5G). We simultaneously consider Wi-Fi offloading and small-cell cooperation to maximize average user throughput in the small-cell network. We propose two heuristic methods, namely Sequential Cooperative Rate Enhancement (SCRE) and Sequential Offloading Rate Enhancement (SORE) to demonstrate cooperation and Wi-Fi offloading, respectively. SCRE is based on cooperative communication in which a user data rate requirement is satisfied through association with multiple small-cell base stations (SBSs). However, SORE is based on Wi-Fi offloading, in which users are offloaded to the nearest Wi-Fi Access Point and use its leftover capacity when they are unable to satisfy their rate constraint from a single SBS. Moreover, we propose an algorithm to switch between the two schemes (cooperation and Wi-Fi offloading) to ensure maximum average user throughput in the network. This is called the Switching between Cooperation and Offloading (SCO) algorithm and it switches depending upon the network conditions. We analyze these algorithms under varying requirements of rate threshold, number of resource blocks and user density in the network. The results indicate that SCRE is more beneficial for a sparse network where it also delivers relatively higher average data rates to cell-edge users. On the other hand, SORE is more advantageous in a dense network provided sufficient leftover Wi-Fi capacity is available and more users are present in the Wi-Fi coverage area.
The current study examined the educational, economic, and sociocultural, family and personal dimensions of delayed marriage among educated females in Pakistan. In addition, it revealed family-based and personal dimensions of delayed marriage among educated females in Pakistan. Furthermore, it highlighted the sociopsychological consequences of delayed marriageability among females in patriarchal society. For this purpose, 35 females, in the age bracket of 30–49 years and with a minimum of 16 years of education, were recruited for the current study through purposive and snowball sampling technique. An interview guide was used as a tool for data collection. The main sociocultural factors of delayed marriageability were the unavailability of a suitable match in the marriage market, the provision of the dowry, the pivotal role of the caste system and the second fiddle role of sectarian affiliation, and previous marital status (engaged or divorced) of the females. The structure and the size of the family were also the decisive family factors of delayed marriageability. Additionally, among personal traits, physical outlook and effective individualism played a prominent role. The current study conjectured a relational insight and transformation in a family structure for family demographers. It was the first qualitative study to highlight the patriarchal perspective of Pakistani society on the factors of delayed marriages. The findings of the current study would enrich the overall theoretical understanding of delayed marriageability among females.
Objective: To compare the efficacy of catheter drainage with incision and drainage in children having soft tissue abscess. Study Design: Randomized Control Trial. Setting: Department of Paediatric Surgery, Allied Hospital Faisalabad. Period: January 2016 to June 2017. Material & Methods: After taking approval from the hospital ethical committee, 160 patients coming through OPD of the department who fulfilled the inclusion criteria were enrolled, and informed consent was taken from them. The patients were randomly divided into two groups using a computer-generated random number table. In group A, patients underwent catheter drainage method, and in group B, patients underwent incision and drainage method. Results: Out of 160 cases (80 in each group), 60% (n=48) in Group-A and 67.5% (n=54) in Group-B were between 1-6 years while 40% (n=32) in Group-A and 32.5% (n=26) in Group-B were 7-12 years of age. 70% (n=56) in Group-A and 67.5% (n=54) in Group-B were males. On efficacy comparison, it was shown that 73.75% (n=59) in Group-A and 47.5% (n=38) in Group-B had efficacy; the p-value was calculated as 0.0007, showing a significant difference. Conclusion: We concluded that catheter drainage is better than incision and drainage in children having soft tissue abscess in terms of length of hospital stay ˂ 24 hours.
Begomovirus is a major and economically important genus of the Geminiviridae family. It comprises a wide range of viruses that infect a number of dicot plants including the horticulture crops, cereal crops, aromatic plants, vegetable crops, medicinal plants and weeds in various regions of the world. This study aims to investigate and correlate the various symptoms of begomovirus / satellites in different plants grown in the vicinity of Kohat, Pakistan. Furthermore, the characterization of the selected virus-associated satellites at the molecular level is also studied. Samples of suspected plants showing begomoviral infection were collected from the Kohat District. Genomic DNA was extracted from the infected plants and subjected to PCR using DNA-1/DNA-2 and Beta01/Beta02 for alpha satellites and beta satellites, respectively. The amplified PCR products were cloned and sequenced commercially. After sequencing, in silico sequence and phylogenetic analysis was also performed. Our study discovered that many plants in the Kohat District display begomovirus and satellite disease symptoms with mild to extreme disease severity. Disease incidence is especially high in okra. Beta satellites were isolated and sequenced from Spinacia oleracea and Capsicum annum plants and they showed more than 90% sequence similarity with chilli leaf curl and tomato leaf curl beta satellites. The existence of betasatellites in spinach and chilli plants was discovered for the first time in the Kohat region. Moreover, the distribution of these highly pathogenic variants of chilli leaf curl and tomato leaf curl betasatellites in the district Kohat has been reported previously.
Pseudotumor is the rare presentation of hemophilia, and is the sign of severe disease. We present a case of 16 years old boy with no known comorbid who presented with pain and swelling around the right distal thigh for one month, his physical examination, laboratory investigation and imaging were suspicious of any malignant pathology. Biopsy was performed and specimen was sent for histopathology, that turned to be clotted blood with no atypical or malignant cells. On the basis of above findings provisional diagnosis of hemophilia was made serum levels of factor VIII were sent and that turned out to be 2.2%. Factor VIII concentrates was administered, swelling around the knee joint gradually subsided after the administration of factor VIII but there was no improvement of range of movement at knee joint.
