Today, worldwide more than five billion of wireless devices are directly communicating for voice and data transmission. The amount of data utilization has increased remarkably and here comes 5G technology with more prominent features, offering high data rate, low latency rate, efficient EM spectrum utilization, an immense machine-2-machine communication, etc. The efficient implementation of 5G technologies requires efficient and compact antennas. This work presents a novel multiband rectangular dielectric resonator antenna for future 5G wireless communication system, having stacked radiator with semi-circular slots etched on the left and right sides of an upper radiator. Additionally, a semi-elliptical slots rectangular microstrip patch antenna of the same dimensions for the purpose of comparison is designed. 28 and 38 GHz, which are the proposed 5G bands by most researchers, are the core target of this work. Alumina with a high relative permittivity of 9.8 is used as a radiator in the design of DRA, while common in the design of both proposed antennas, Rogers RT/DUROID 5880 with a relative permittivity of 2.2 having standard thickness is used as substrate material. Both the proposed antennas have an overall same size of 13 × 11.25 mm 2. The proposed dielectric antenna resonates at 25.4, 34.6 and 38 GHz with 7.34, 4.04, and 3.30 GHz of wide impedance bandwidth covering the targeted 5G, 28, and 38 GHz bands, having a good return loss of −34.7, −31.8, and −33.5 dB, respectively. Further, the proposed dielectric antenna has a maximum radiation efficiency of 97.63%, with overall radiation efficiency greater than 90%, and maximum gain of 7.6 dBi is also noted. On the other hand, the proposed microstrip antenna resonates at 28 and 38 GHz with a 1.49 and 1.01 GHz of moderate impedance bandwidth, having −23.6 and −27.1 dB of satisfactory return loss. Further, the proposed patch antenna has a maximum radiation efficiency of 90.33% at 28 GHz, with overall radiation efficiency of greater than 84%, and moderate gain of 5.45 dBi is also noted. Both the proposed antennas have a nearly omnidirectional radiation pattern at resonance frequencies, with VSWR less than 2. Comparative study of the two proposed antennas regarding radiation efficiency, return loss, gain, data rate, and impedance bandwidth evidently shows that performance of DRA over MPA at millimeter wave is very good. The proposed antennas are simulated in CST Microwave studio v18.

The study compared the students' level of understanding using two scenarios i.e. S1 (Classroom Lectures) and S2 (Lectures based on AR). An independent sample t-test was applied to correlate the results of two groups (experimental and control) and paired sample t-test was applied to evaluate the two scenarios S1and S2 within two groups: the experimental and the control. When the effect of augmented reality in blended learning framework is broke down, it is examined that augmented reality learning outperform classroom learning environment in enhancing students' performance. The result revealed that there is a difference between classroom learning and AR learning. AR experiences have positive effect on students' learning. Furthermore, students' confidence and motivation towards learning are achieved.

Overview Dengue fever, a viral illness transmitted by the Aedes mosquito, is capable of causing a range of serious complications, including fulminant hepatic failure, renal dysfunction, encephalitis, encephalopathy, neuromuscular and ophthalmic disorders, seizures, and cardiomyopathy. Case description This report details the case of a 30-year-old lactating woman with no notable medical history who presented to the emergency department with symptoms of high-grade fever, altered mental status, and seizures. Upon imaging, bilateral infarcts in the thalami and cerebellar hemispheres were observed, consistent with cerebellitis and dengue encephalitis. Patient treatment and outcome The patient was admitted to the intensive care unit and received appropriate treatment. Following a critical phase and successful patient stabilization, she was transferred to a high dependency unit for a week before being discharged with recommendations for follow-up care. Conclusion This case illustrates the broad spectrum of complications that can arise as a result of dengue infection and the importance of timely diagnosis and management in improving patient outcomes. Further investigation is required to better understand the mechanisms underlying these complications and to formulate specific guidelines for the prevention and treatment of dengue shock syndrome.

14 September, 2019 Accepted: 07 October, 2019Abstract: Deforestation and forest degradation are not only a problem of north western mountainous region of Pakistanbut it is one of the main global environmental issues. To find out deforestation rate and its extent in Swat, KhyberPakhtunkhwa, Landsat 5 (October 2, 2011) and Landsat 8 OLI (October 15, 2016) data were processed in CarnegieLandsat Analysis System (CLASlite v3.3). Primary data related to deforestation in Swat were also obtained from localpeople through a structured questionnaire. Primary data were analyzed in Statistical Package for the Social Sciences(SPSS). Changes in land cover can be clearly identified during image analysis. The temporal analysis of forest coverbetween 2011 and 2016 showed a significant change in forest cover. About 11 km² area is converted from forest tobarren land, while approximately 9,985 km² area of forest cover was degraded. The perceived causes of deforestation inthe study area are unsustainable use and mismanagement of forest resources, population growth, plantation ofeucalyptus and lack of basic facilities and awareness. However, community ignorance is the main factor responsible fordeforestation and forest degradation. One of the major consequences of deforestation can be related to the totaldisappearance of Charchur waterfall in Talang Kota lower Swat in September 2016. Therefore, it is the right time tomove toward sustainable management, detection and monitoring of national forest reserves by using geospatial tools,and by the involvement of local communities to participate in decision making about the conservation of forestresources.
