Sleep restriction is now considered to be a worldwide epidemic, as over 20% of people around the world are sleep deprived. Although sleep deprivation is now an overlooked feature of modern societies, it entails considerable adverse effects on physiological systems, one being energy homeostasis. A corpus of research has demonstrated that leptin, a key hormone that conveys the body's energy status to the brain, decreases after sleep restriction, which may partly account for the associated alteration in body metabolism; however little information is available regarding the underlying ...

Bitcoin is the most popular purely digital cryptocurrency nowadays. It started in 2009 as a peer to peer payment system, decentralized, pseudo-anonymous and secure system of money. The main objective of this study is to estimate and predict the weekly close bitcoin price by including other variables like commodities, indexes and demand / supply variables through different kind of machine learning and deep learning such as multiple regression, time series ARIMA model, artificial neural network, combination of multiple regression and ARIMA model, and finally combination of multiple regression, ...

“In the truth there is no news and in the news there is no truth”, a soviet-era political joke, still applies to the present times. This study will highlight all the communication forms and how they are used nowadays as a tool for propaganda especially in the digital world. When website traffic, clicks, and reach are at stake, information disorder in the form of misleading/fake information would be used as a tool to enhance data metrics across the digital world. This study tackles information disorder during all its phases: creation, production, communication, and the user experience through ...

The 80/20 rule says that 20% of the customers produce 80% of the sales; this rule indicates the existence of hidden sales potentials that must be revealed. Those hidden sales potentials can only be discovered by building acustomer profile. A smart customer profile finds the high potential targets, creates CRM strategies, and starts programs to sell the hidden targets. Shifting just a small percentage of the customers whom are not generating profit to the top group of customers generating profit adds significantly sales growth increase profits. Customer profile puts the full picture together to ...

Antibiotic resistance and prevalence of hospital (HAI) and community-acquired (CAI) infections are significantly increasing in the world, though very few studies are addressing this topic in Lebanon. Therefore, this meta-analysis aims to identify antibiotic (AB) resistance prevalence among hospital and community acquired infections. Literature databases were searched for antibiotic resistance, HAI, and CAI in Lebanon from 2010 to 2020. To be eligible for inclusion, studies had to report data in Lebanon published between 2010 and 2020, antibiotic resistance in microorganisms responsible for either ...

Herein, we describe, a simple method for the synthesis of dendrigraft poly-L-lysine (d-PLL) coated gold nanoparticles in water (AuNPs-d-PLL) as potential vehicles of siRNA delivery to prostate cancer cells, PC3-PSMA. AuNPs-d-PLL with diameters ranging between 50 ̶ 130 nm have been synthesized in aqueous solutions using d-PLL (7 KD) as a capping ligand and L-ascorbic acid as a reducing agent. The size of the resulting AuNPs was found to depend on several parameters, such as the concentrations of gold salt, reducing agent, and d-PLL. The obtained AuNPs-d-PLL were characterized using UV-visible ...

Retail space planning is an accurate and complex process affecting the overall performance of a retail environment. Such task, confronting large retailers consisting of huge malls and hypermarkets, appears infinite in the absence of a complete automated process, starting from the store plan generation, passing by the optimal product assortment and finishing with the product-to-shelf allocation problem. Moreover, the ever-changing factors affecting the retail space planning process, such as merchandising rules, competitive strategies and consumer behavior require continuous follow-up and optimization ...

The Dark Ages, a period stretching from 400 thousand years to 400 million years after the big bang, is the least known era in the evolution of our universe, as no visible light was emitted. However, another type of radiation was available, the Hydrogen 21cm. It reaches us at frequencies between 1.5 and 30MHz. The ideal way to detect it, involves antennas placed in a fixed orbit around the dark side of the moon where it is shielded from electromagnetic interference emitted from earth.

Enterprise Resource Planning (ERP) systems are vital for managing any modern-day business. These systems aim to facilitate an organization's work by automating and integrating all business information and processes. However, ERP systems suffer from many problems that may cause an implementation failure. Many of these problems are related to usability, which is affected by the complexity of user interfaces (Uls). Usability can be defined in terms of an end-user's efficiency, effectiveness, and satisfactions. A study was conducted in this thesis to inquire about the usability problems that ...

Yerba Mate (Ilex paraguariensis) is a beverage that is highly consumed by certain communities in Lebanon. Several studies have shown the benefits of yerba mate consumption on one's health. Also, Lebanese add to their hot drink some medicinal plants that have been acquired by the society from the Arabian folk medicine. Many studies have been conducted, yet little is known about its effect on the Lebanese health, as they have been consuming it for almost 100 years. Therefore, this study was done to assess the use of yerba mate and medicinal plants. A questionnaire was distributed among 200 local ...
