Houshold waste is the residue generated daily by people as a result of consuming goods and services. The qualitative and quantitative aspects depend on the lifestyle and standard of living of citizens. Hence a change in habits, following an economic or health crisis, can influence the production of waste and its composition. The objective of the present work is to assess the impact of lockdown ...

We describe, build, and evaluate Lockdown, a system that significantly increases the level of security for online transactions, even on a platform infested with malicious code. Lockdown provides the user with a highly-protected, yet also highly-constrained trusted environment for performing online transactions, as well as a high-performance, general-purpose environment for all other (non-securi...

During crisis events, people often seek out event-related information to stay informed of what is happening. However, when information from official channels is lacking or disseminated irregularly, people may be at risk for exposure to rumors that fill the information void. We studied information-seeking during a university lockdown following an active-shooter event. In study 1, students in the...

Applications written in low-level languages without type or memory safety are especially prone to memory corruption. Attackers gain code execution capabilities through such applications despite all currently deployed defenses by exploiting memory corruption vulnerabilities. Control-Flow Integrity (CFI) is a promising defense mechanism that restricts open control-flow transfers to a static set o...

Applications written in low-level languages without type or memory safety are prone to memory corruption. Attackers gain code execution capabilities through memory corruption despite all currently deployed defenses. Control-Flow Integrity (CFI) is a promising security property that restricts indirect control-flow transfers to a static set of well-known locations. We present Lockdown, a modular,...

Several measures have been taken to mitigate the effects of COVID-19 pandemic. In this context, almost all non-essential activities in Morocco halted since March 20, 2020. From that date, announced lockdown for one month and it was extended until June 10, The main objective paper is study on air quality, by analyzing dust PM2.5, NO2, O3. PM2.5 analysis carried out from 2016 NO2 O3 2019 This stu...

The administrator of an enterprise network has a responsibility to enforce the policies on the network. Yet, most security mechanisms do not map well to the intended policies. This has been due to the prevalence of simplistic tools that have poor enforcement but, yet are easy to manage. While advanced commercial solutions do exist that have stronger enforcement, they are significantly harder to...

BACKGROUND Little is known about HIV-1 subtype distribution in Morocco. Some data suggest an emergence of new HIV subtypes. We conducted phylogenetic analysis on a nationally representative sample of 60 HIV-1 viral specimens collected during 2004-2005 through the Morocco national HIV sentinel surveillance survey. RESULTS While subtype B is still the most prevalent, 23.3% of samples represente...

Background and Objectives: The COVID-19 pandemic and consequent lockdown has multifaceted effects on people’s life including fall in economy which may affect food choices. This study was designed to evaluate changes in dietary intakes of the Iranian households during COVID-19 lockdown and also to predict the consequent health impacts. Materials and Methods: This cross-sectional descriptive-ana...
