Field studies have identified alkylammonium salts as important components of secondary marine organic aerosols. In this work, we study the hygroscopic behavior of laboratory-generated alkylammonium aerosol particles, including monomethylammonium chloride (MMACl), dimethylammonium chloride (DMACl), trimethylammonium chloride (TMACl), diethylammonium chloride (DEACl), and their mixtures with inorganic salts containing ammonium sulfate (NH4)2SO4, sodium chloride NaCl, calcium nitrate Ca(NO3)2 and sodium sulfate Na2SO4 at different dry mass ratios with a hygroscopicity tandem differential mobility analyzer (HTDMA). The hygroscopic growth of pure alkylammonium salt particles (except for DEACl) reveals gradual water uptake over the whole studied range of relative humidities (RHs). In general, the impact of the presence of alkylammonium chloride on the phase behavior and hygroscopic growth of mixtures depends on the chemical composition of particles and volume fraction of the alkylammonium chloride in the mixtures. he ZSR predictions for different alkylammonium/inorganic mixtures are similar to the measured GFs as long as the mixed particles are in a liquid-like state.The increasing salinization in the soil profile by irrigation water and groundwater upheaval is a widespread issue and considered as a major threat to agricultural production in arid and semi-arid regions. The present study aimed to propose a systematic SAR simulation involving the imaginary part of dielectric constant measurements of two consecutive seasons (dry and wet) to quantify and discriminate the irrigation-induced and upheaval-associated salinity from total salinity levels and investigate its impact on crop growth. The Sentinel-1 data of C-band frequency (5.36 GHz) acquired for both the dry and wet spells from 2015 to 2019 was instrumental in the present study. The total soil EC (Electrical Conductivity) was quantified from the imaginary part of dielectric constant (ε″) using semi-empirical microwave simulation "DSDM-SS". selleck inhibitor Irrigation-induced salinity (εIrrigation″) and upheaval-associated salinity (εUpheaval″) were extracted from ε″ by proposing a site-, and climatic-specific novel model. The εUpheaval″ and εIrrigation″ have shown promising statistical significance with the in-situ soil EC (R2 = 0.89, p = less then 0.001, rMSE = 1.08, Bias = 0.584) and groundwater EC measurements (R2 = 0.85, p = less then 0.001, rMSE = 1.28, Bias = 1.16). The study found that the rate of salinity increase over time due to irrigation (77%) was considerably higher than the upheaval (42%) process. This demonstrated that the intensive use of groundwater for irrigation has a higher impact on vegetation vigor (θ = -0.87) than the upheaval process. The study revealed that crop failure in the dry season was provoked by osmotic stress and waterlogging conditions.For many individuals, living with epilepsy is truly a family affair throughout the life span. When it comes to childhood epilepsy, the unpredictability of seizure patterns, comorbid conditions, the risk of sudden unexpected death in epilepsy (SUDEP), and societal stigma can be emotionally taxing on children and their primary caregivers. To this end, this article proposes to review psychoeducational interventions provided to primary caregivers of children with an epilepsy diagnosis and the impact of such interventions on general parental coping skills. There were three main themes identified (1) caregivers' knowledge and self-efficacy about seizure management; (2) parental epilepsy-related fears, anxiety, and stress; (3) parental sleep quality and SUDEP psychoeducation. Overall, considering research limitations, providing epilepsy-related psychoeducational interventions to primary caregivers of children with epilepsy seems to have promising evidence in the literature. After receiving such interventions, the studies show that caregivers' psychosocial outcomes improved; they become more empowered to manage their children's seizures and advocate for their children's psychosocial needs.This exploratory study provides an overview of Arabic language content for epilepsy available on three social media platforms Facebook, Twitter, and YouTube, from the time that the platforms came into being up to the end of the year 2020. Two Arabic keywords that mean "epilepsy" and "convulsion" were used on the search engine of each platform to extract related content. Two reviews were conducted for 300 randomly selected pages, accounts, and videos from a total of 795 related published ones on the targeted platforms. Results revealed that Arabic language content related to epilepsy on social media platforms has been available for about one decade. Various sources from almost all Arab countries contributed to the content. Most of the content (43%) was from medical and healthcare professionals and institutions. Definition and classification of epilepsy were the most common topics (21%) within posts and shares. Moreover, seeking information and advice were the dominant types of engagement found among users (32%). Findings of the study suggest that more attention on content for underrepresented topics is required and that enhanced engagement by health professionals and specialists with the users on social media platforms would be beneficial. Implications for current use and available content related to epilepsy on social media, as well as related recommendations, are included.Long-term stability of retention times of a wide range of analytes has been evaluated using eight different stationary phases. These were from a single manufacturer to minimize the differences in silanol activity caused by the manufacturing process. The tested stationary phases included bridge ethylene hybrid, 2-ethylpyridine bridge ethylene hybrid with direct modification of silica particles, bidentate crosslinked charged surface hybrid fluorophenyl, bidentate crosslinked high strength silica C18, and propanediol linked phases including diol (pure propanediol linker), and three phases based on diol further modified with 2-picolylamine, diethylamine, and 1-aminoanthracene group. Retention times were monitored at the first injection, after three, nine, twelve months, and after the column regeneration via washing with pure water. The analyses were carried out using three different mobile phases, including methanol, methanol with 10 mmol/L ammonium formate, and methanol with 0.1% ammonium hydroxide. No overall decreasing or increasing trends were observed after evaluating individual contributing parameters such as analyte, stationary phase, and organic modifier.
