Materials: Cyclohexane, n-hexanol (98%), ammonia hydroxide (28~30 wt%), tetraethylorthosilicate (TEOS, 98%), (3-aminopropyl)trimethoxysilane (APTS, 95%), polyoxyethylene(10)isooctylphenylether (TritonX-100), fluorescein isothiocyanate isomer I (FITC, 90%), Iron(III) acetyl acetonate (Fe(acac)3, 99+%), and benzyl ether (99%) were purchased from Acrös. 1,2 dodecanediol (90%), oleylamine, and olei...

Crisotila natural e quimicamente modificada foi usada como matrizes para imobilização de ferroporfirinas de segunda geração. As atividades catalíticas dos sólidos obtidos foram avaliadas em reações de oxidação de cicloexano, usando iodosilbenzeno como oxidante. Os resultados de catálise foram analisados e comparados aos obtidos pela imobilização das mesmas ferroporfirinas em sílica funcionaliza...

As adversaries evolve their Tactics, Techniques, and Procedures (TTPs) to stay ahead of defenders, Microsoft’s.NET Framework emerges as a common component found in the tradecraft many contemporary Advanced Persistent Threats (APTs), whether through PowerShell or C#. Because of.NET’s ease use availability on every recent Windows system, it is at forefront modern TTPs primary means exploitation. ...

Attacks on the cyber space is getting exponential in recent times. Illegal penetrations and breaches are real threats to individuals organizations. Conventional security systems good enough detect known but when it comes Advanced Persistent Threats (APTs) they fails. These APTs targeted, more sophisticated very persistent incorporates lot of evasive techniques bypass existing defenses. Hence, t...

Multi-electron dynamics in atoms and molecules very often occur on sub- to few-femtosecond time scales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have previously allowed the time-resolved investigation two-photon, two-electron interactions. Here we study double triple ionization argon involving absorption up five XUV photons using a pair intense pulse trains (APTs...

Nanoparticles (NPs) may affect the lung via their chemical composition on the surface. Here, we compared the bioactivity of zirconium oxide (ZrO₂) NPs coated with either aminopropilsilane (APTS), tetraoxidecanoic acid (TODS), polyethyleneglycol (PGA), or acrylic acid (Acryl). Supernatants from NPs-treated cultured alveolar macrophages (NR8383) tested for lactate dehydrogenase, glucuronidase, tu...

Google’s software update system can serve as a model Advanced Persistent Threat (APT). APTs often embed programs in a penetrated system. These programs wake up from time to time, call home, download additional programs and instructions to carry out, and modify systems. Google’s software update performs all these steps too. Furthermore, because the Google Chrome browser is so widely used and upd...

A major cause of implant failure in skeletal tissues is failure of osseointegration, often due to lack of adhesion of cells to the titanium (Ti) alloy interface. Since arginine-glycine-aspartic acid (RGD)-containing peptides have been shown to regulate osteoblast adhesion, we tested the hypothesis that, bound to a Ti surface, these peptides would promote osteoblasts differentiation, while at th...

Developing a detailed threat profile, provides organizations with a clear illustration of the threats that they face, and enables them to implement a proactive incident management program that focuses on the threat component of risk. Organizations are facing new types of advanced persistent threat (APT) scenarios that existing risk management programs are not able to evaluate completely and inc...

The emergence of the occipital alpha rhythm on brain electroencephalogram (EEG) is associated with brain activity in the cerebral neocortex and deep brain structures. To further understand the mechanisms of alpha rhythm power fluctuation, we performed simultaneous EEGs and functional magnetic resonance imaging recordings in human subjects during a resting state and explored the dynamic relation...
