Making Linux protection mechanisms egalitarian with UserFS
UserFS provides egalitarian OS protection mechanisms in Linux. UserFS allows any user-not just the system administrator-to allocate Unix user IDs, to use chroot, and to set up firewall rules in order to confine untrusted code. One key idea in UserFS is representing user IDs as files in a /proc-like …

Protection mechanisms against excess light in Myrothamnus flabellifolius (Welw.)
… a control, in the dark. The effects on the photoprotection mechanisms were assessed. Differences in water content, quantum efficiency of photosystem II. chlorophyll (a+b) content, carotenoid content. anthocyanin contents were measured during dehydration and rehydration. Ultrastructural studies …

Identification of Privacy Risks for Android Users and Effective Protection Mechanisms
During the last few years, smartphones have seen a marked increase in popularity, due to its many attractive features such as GPS functionality and apps such as e-mail clients, address book, and many more. The world’s most popular mobile Operating System is Android, consequently Android devices are …

Protection Mechanisms of Excipients on Lactate Dehydrogenase during Freeze-Thawing and Lyophilization
… was to elucidate the protective effects and mechanisms of excipients on a labile model protein, lactate dehydrogenase (LDH), during freeze-thawing and lyophilization. Cryoprotectants are excipients that protect labile molecules during freezing. Some investigators believe that preferential …

Corrosion protection mechanisms of trivalent chromium based passivations on γ-ZnNi coated Al6061-T6 alloy
… on the Al 6061-T6 specimens showed active protection from TCP and not cobalt-free TCP indicating a chemical rather than physical difference. Confounding factors of electroless nickel (EN) between the substrate and γ-ZnNi coating and heat treatments led to Al 6061-T6 panels that were heat …

Ultraviolet radiation and aquatic bryophytes: physiological damage and protection mechanisms under laboratory and field conditions
La degradación de la capa de ozono estratosférico provoca un aumento de radiación ultravioleta-B (UV-B) en la Biosfera, lo que puede afectar a los organismos fotosintéticos. Dado que los briófitos de arroyos de montaña se han estudiado poco en este sentido, el objetivo de esta Tesis era profundizar …

Socio-economic rights in Africa: a critical evaluation of legal protection mechanisms and Implementation strategies
… from the dynamic interplay of legal protection mechanisms and implementation strategies, as we!! as the problematics involved therein, this study proffers viable trajectories for concerted activism at the levels of the civil society in Africa.

Introducing Privacy in Current Web Search Engines
… introduce SimAttack an attack against existing protection mechanism to query search engines in a privacy-preserving way. This attack aims at retrieving the original user query. We show with this attack that three representative state-of-the-art solutions do not protect the user privacy in a …

Efficient and Verifiable Timing Channel Protection for Multi-Core Processors
… because they can bypass traditional defense mechanisms such as access control. Previous studies have even demonstrated a practical timing channel attack to recover the keystrokes of a user in the commercial Amazon EC2 cloud. In this thesis, we explored new timing channel attacks and developed …

Korrosionsschutz von Eisenwerkstoffen durch intrinsisch leitfähige Polymere
The corrosion protection of intrinsically conducting polymers (ICP) for mild steel is studied with polymethylthiophene films (PMT). Homogeneous and very adherent PMT films are formed on mild steel if the surface is pretreated with 2(3-thienyl)ethylphosphono acid used as adhesion promoter (AP). The …

The use of mutual hostages and protection mechanisms enhances partner cooperation, while performance ambiguity and organizational differences between partners impact cooperation negatively. The use of mutual hostages also improved joint venture performance, while protecting one's …

Stomatal control during dessication in the resurrection plant Xerophyta humilis
… the drying rate of the plant, this gave time for protection mechanisms to be laid down. The signal hormone ABA was found to have strong stomatal control on the adaxial surfaces of leaves but weak control on the abaxial leaf surfaces, thus it is difficult to say that ABA regulates the process until …

We are then identifying the flaws of the protection mechanisms in each province, and are showing that taking user rights seriously means giving them some rights against the State. Lastly, we establish the necessity of …
