Estimation of Rain Attenuation at EHF bands for Earth-to-Satellite Links in Bangladesh
Due to heavy congestion in lower frequency bands, engineers are looking for
new frequency bands to support new services that require higher data rates,
which in turn needs broader bandwidths. To meet this requirement, extremely
high frequency (EHF), particularly Q (36 to 46 GHz) and V (46 to 56 GHz) bands,
is the best viable solution because of its complete availability. The most
serious challenge the EHF band poses is the attenuation caused by rain. This
paper investigates the effect of the rain on Q and V bands' performances in
Bangladeshi climatic conditions. The rain attenuations of the two bands are
predicted for the four main regions of Bangladesh using ITU rain attenuation
model. The measured rain statistics is used for this prediction. It is observed
that the attenuation due to rain in the Q/V band reaches up to 150 dB which is
much higher than that of the currently used Ka band. The variability of the
rain attenuation is also investigated over different sessions of Bangladesh.
The attenuation varies from 40 dB to 170 dB depending on the months. Finally,
the amount of rain fade required to compensate the high rain attenuation is
also predicted for different elevation angles.Comment: Int'l Conf. on Electrical, Computer and Communication Engineering

Endovascular Cure of a Locked-In Patient
We report the case of a 60 year-old right-handed gentleman who became acutely “Locked-In” several days after a lower extremity orthopedic procedure. He underwent emergent endovascular treatment and had complete resolution of his neurologic findings except for mild dysarthria and dysphagia. Endovascular intervention for posterior circulation thrombosis is highly effective when patients are treated within 24 hours
The Use of Palliative Performance Score in Patients with End-Stage Liver Disease
● Palliative Care services are often underutilized in patients with End-Stage Liver Disease (ESLD) and often only initiated at the end of life
● The Palliative Performance Score (PPS) is an important tool used in Palliative Care to assess functional status
● PPS has five functional dimensions: ambulation, activity level and evidence of disease, self-care, oral intake, and level of consciousness
● The aim of this study is to determine if there is a correlation between Model for End-Stage Liver Disease (MELD) score and PPS in ESLD patients
● MELD is used to predict mortality and to prioritize liver transplant allocation in ESLD patientshttps://jdc.jefferson.edu/medposters/1011/thumbnail.jp
Obstructive sleep apnea syndrome and perioperative complications: a systematic review of the literature.
Obstructive sleep apnea syndrome (OSAS) is a common sleep related breathing disorder. Its prevalence is estimated to be between 2% and 25% in the general population. However, the prevalence of sleep apnea is much higher in patients undergoing elective surgery. Sedation and anesthesia have been shown to increase the upper airway collapsibility and therefore increasing the risk of having postoperative complications in these patients. Furthermore, the majority of patients with sleep apnea are undiagnosed and therefore are at risk during the perioperative period. It is important to identify these patients so that appropriate actions can be taken in a timely fashion. In this review article, we will discuss the epidemiology of sleep apnea in the surgical population. We will also discuss why these patients are at a higher risk of having postoperative complications, with the special emphasis on the role of anesthesia, opioids, sedation, and the phenomenon of REM sleep rebound. We will also review how to identify these patients preoperatively and the steps that can be taken for their perioperative management

A Week Devoted to Wellness in the Preclinical Phase: Lessons Learned
Background
During the 2017-2018 academic year, a large private medical college underwent a complete transformation of its curriculum from a primarily lecture based, traditional format to an integrated, longitudinal format that included both time limited blocks and longitudinal threads of content. Wellness, conceptualized at both wellness of the provider and the patient, is one of the eight threads.
Goals Provide a structured pause in medical school for you to reflect on your own wellness Allow time to explore the ideas of resilience Provide time for rejuvenation Allow you to start building productive habits to last you throughout your entire medical careershttps://jdc.jefferson.edu/rmposters/1005/thumbnail.jp
The social and community value of football - Are there any regulatory requirements for football clubs to report against social and environment impacts?
It is often claimed that because professional football clubs are at the centre of, integral to
and essential for the communities in which they are based, the pattern of regulation affecting
them should be different from that which is imposed on other businesses of a similar size.
Such claims are used to justify the need for the differential treatment of football clubs in
many different contexts from planning and licensing applications, to calls for the more
effective regulation of football clubs from supporter groups, to the rule providing for the
primacy of football creditors. Despite this claim of difference, however, neither the football
authorities, domestic UK law nor EU law require football clubs to submit to any social
accounting procedures. The result of this lack of a framework for measuring the social and
community impact of a football club is that there is very little evidence that can be relied on
by either the governing bodies of football, their constituent member clubs or their fans to
justify the differential treatment that is often sought. Further, this lack of evidence makes it
almost impossible to justify to clubs why it could be beneficial for them to engage with their
communities more proactively than might otherwise be the case
