However, many of these alternative social media platforms have evolved to be outlets for hate speech and violent extremism. This study examines hate-based channels on Telegram from a US perspective. While Telegram has often been studied in relation to ISIS, less is known about its usage by US extremist users and movements. The authors used OSINT and observational methods on a sample of 125 Telegram channels containing hate speech and violent extremist content from far-right and far-left perspectives. The authors hypothesized that there would be a greater and growing presence of far-right activity compared to farleft activity due to current migration trends away from mainstream social media by the far-right. The authors also sought to observe the presence of disinformation campaigns, conspiracy theories, and accelerationism on Telegram. This study had four major findings: (1) the findings supported the hypothesis that more channels were host to farright dialogues, yet there were several far-left channels present, (2) 64.8% of the channels grew in size over a oneweek period, (3) 47 of the 125 channels were connected to well-known violent extremist movements or hate groups, and (4) QAnon and the COVID-19 pandemic were the most prominent sources of disinformation and conspiracy theories on Telegram. The findings of this study highlight that alternative social media platforms are a growing environment for a range of hateful ideologies and are aiding the spread of disinformation campaigns. This study concludes with a discussion on future strategies to combat the influence of the Internet on radicalization outcomes.

However, many of these alternative social media platforms have evolved to be outlets for hate speech and violent extremism. This study examines hate-based channels on Telegram from a US perspective. While Telegram has often been studied in relation to ISIS, less is known about its usage by US extremist users and movements. The authors used OSINT and observational methods on a sample of 125 Telegram channels containing hate speech and violent extremist content from far-right and far-left perspectives. The authors hypothesized that there would be a greater and growing presence of far-right activity compared to farleft activity due to current migration trends away from mainstream social media by the far-right. The authors also sought to observe the presence of disinformation campaigns, conspiracy theories, and accelerationism on Telegram. This study had four major findings: (1) the findings supported the hypothesis that more channels were host to farright dialogues, yet there were several far-left channels present, (2) 64.8% of the channels grew in size over a oneweek period, (3) 47 of the 125 channels were connected to well-known violent extremist movements or hate groups, and (4) QAnon and the COVID-19 pandemic were the most prominent sources of disinformation and conspiracy theories on Telegram. The findings of this study highlight that alternative social media platforms are a growing environment for a range of hateful ideologies and are aiding the spread of disinformation campaigns.

The adsorption process is an alternative way to remove heavy metal ions. The polymer-based adsorbent was chosen as material to remove heavy metal ions due to its economic cost, can be prepared with convenient method and excellent capability to make high adsorption towards metal ions. In this study, the synthesis and modification of amidoxime (AO) modified poly(acrylonitrile-co-acrylic acid) (poly(ANco- AA)) was carried out. Next, the effect of adsorption parameters, equilibrium and kinetic studies of cadmium ion (Cd2+) and lead ion (Pb2+) were investigated. The optimisation of adsorption parameter was analysed using Response surface methodology (RSM). The poly(AN-co-AA) was synthesised via redox polymerisation and was further chemically modified with hydroxylamine hydrochloride to produce AO modified poly(AN-co-AA) as adsorbent. Then, single batch syst...

They do not notice that there have risks of interactions between herbs and drug leading to toxicity or loss of therapeutic efficacy. The purpose of this study is to evaluate the interactions of Malaysian traditional herbs with CYP1A2 enzymes. CYP1A2 is one of the major member of CYP and it constitute about 12-20% of the total CYP content and it mostly a hepatic enzymes. Vivid®CYP450 Screening Kit had been use to study the inhibition activity of Malaysian traditional herbs. α-naphthoflavone is use as positive control that showed 100% inhibition and solvents control which is DMSO showed 0% inhibition or no inhibition. Result showed 27 herb which are Biji kedaung, Bunga mukmin, Cabai pintal, Getah katira, Halba, Kadukai besar, Kadukai kecil, Kacip Fatimah, Kayu angin, Kayu lilit, Ketumbar, Kulit kayu manis, Lada pahit, Lebai samad, Lengkuas, ...
