Novel Preparation and Characterization of Zinc Ricinoleate Through Alkali Catalysis.

The enhanced thermal and chemical stability of Zinc oxide-based materials make them excellent candidates for the removal of odor-producing pollutants and compounds. The zinc salt of ricinoleic acid, commonly known as zinc ricinoleate, is viewed as the top performer. This article describes an innovative two-step synthesis of zinc ricinoleate, where the first step consists of the preparation of an intermediate compound, methyl ricinoleate, which is synthesized via transesterification of castor oil with methanol and catalyzed by sodium hydroxide.

The Influence of Activated Sludge Augmentation on Its Ability to Degrade Paracetamol.

Paracetamol is one of the most commonly used painkillers. Its significant production and consumption result in its presence in the environment. For that reason, paracetamol has a negative impact on the organisms living in ecosystems.

Enhancement of integrated nano-sensor performance comprised of electrospun PANI/carbonaceous material fibers for phenolic detection in aqueous solutions.

The detection of trace levels of organic residue in water samples is a key health issue. This manuscript describes the fabrication of integrated nano-sensors composed of electrospun microfibers consisting of a nanocomposite of carbonaceous materials (CNMs) containing polyaniline (PANI) and polycaprolactone (PCL) for phenolic detection in aqueous solutions. The morphology of the resulting microfiber composite was characterized by scanning electron microscopy.

What Counteracts Problematic Social Media Use in Adolescence? A Cross-National Observational Study.

Purpose: Social media use has increased rapidly during the past decade, raising concerns about adolescents who display problematic social media use (PSMU), as indicated by addiction-like symptoms (e.g., preoccupation, tolerance).

Selective enrichment, identification, and isolation of diclofenac, ibuprofen, and carbamazepine degrading bacteria from a groundwater biofilm.

Diclofenac, ibuprofen, and carbamazepine are three of the most widely detected and most concerning pharmaceutical residues in aquatic ecosystems. The aim of this study was to identify bacteria that may be involved in their degradation from a bacterial biofilm. Selective enrichment cultures in mineral salt solution containing pharmaceutical compounds as sole source of carbon and energy were set up, and population dynamics were monitored using shotgun metagenome sequencing.

Grafting of Poly(ethylene imine) to Silica Nanoparticles for Odor Removal from Recycled Materials.

One of the major obstacles to the reuse of recycled plastic materials is the emanation of after-process odors from recycled polymers and composites. Typically, recycled polymers are blended with an off-odor adsorbent additive in the recycling chain to eliminate these smells. This article describes an innovative ultrasonically assisted method of grafting poly(ethylene imine) (PEI) to silica nanoparticles (SiO) initiated by benzoyl peroxide (BP) which acts as an odor remover.

From the same enrichment an aerobic actinobacterium, strain CBZ_1, sharing 99.4% whole-genome sequence similarity with the reconstructed Nocardioides sp.

Hydrogen Production in Microbial Electrolysis Cells Based on Bacterial Anodes Encapsulated in a Small Bioreactor Platform.

Microbial electrolysis cells (MECs) are an emerging technology capable of harvesting part of the potential chemical energy in organic compounds while producing hydrogen. One of the main obstacles in MECs is the bacterial anode, which usually contains mixed cultures. Non-exoelectrogens can act as a physical barrier by settling on the anode surface and displacing the exoelectrogenic microorganisms.

Students' Emotional Well-Being, and Perceived Faculty Incivility and Just Behavior Before and During COVID-19.

This research set out to measure the impact of the lockdown condition and social distancing imposed on higher education by the Israeli government during the COVID-19 period and the shift to online learning, on students' emotional well-being, the way they perceived their teachers' just behavior, and faculty incivility, compared to pre-pandemic conditions. An additional aim was to explore the set of connections among these factors. The total sample included 396 undergraduate students from three academic colleges.

Does the League Table Lie? The Development and Validation of the Perceived Performance in Team Sports Questionnaire (PPTSQ).

Objective performance measures are vastly used in sport psychology despite their inherent limitations (e.g., unaccounted baseline differences).

A tailored permeable reactive bio-barrier for groundwater remediation: removal of 3-chlorophenol as a case study.

The present study explored bacterial aerobic biodegradation of reduced carbon-contaminants (RCC) in a pilot system mimicking remediation of a saturated aquifer in a permeable reactive biobarrier (PRBB). Bioaugmentation was performed with a pure culture of macro-encapsulated in a cellulose-acetate porous envelope and integrated transversely to the flow trajectory of the fluid in the biobarrier and compared with controls without capsules. The macro-encapsulation technique applied allowed the incorporation of a built-in nutrient core for the slow release of macronutrients, i.

Item Features Interact With Item Category in Their Influence on Preferences.

Low-level visual features are known to play a role in value-based decision-making. However, most previous studies focused on the role of only a single low-level feature or only for one type of item. These studies also used only one method of measurement and provided a theory accounting for those specific findings.

Network Neuromodulation of Opioid and GABAergic Receptors Following a Combination of "Juvenile" and "Adult Stress" in Rats.

Early life stress is suggested to alter behavioral responses during stressful challenges in adulthood and to exacerbate pathological symptoms that reminisce posttraumatic stress disorder (PTSD). These effects are often associated with changes in γ-Aminobutyric acid type A (GABAA) and κ opioid receptor expression and neuromodulation of the limbic system. Anxiety-like and stress coping behaviors were assessed in rats exposed to stress in adulthood on the background of previous exposure to stress in juvenility.

Social Media Use and Cyber-Bullying: A Cross-National Analysis of Young People in 42 Countries.

Purpose: Social media use (SMU) has become an intrinsic part of adolescent life. Negative consequences of SMU for adolescent health could include exposures to online forms of aggression. We explored age, gender, and cross-national differences in adolescents' engagement in SMU, then relationships between SMU and victimization and the perpetration of cyber-bullying.

Is a family-centred initiative a family-centred service? A case of a Conductive Education setting for children with cerebral palsy.

Background: From the moment a child is diagnosed as having cerebral palsy, families have to cope on a daily basis with the multifaceted challenges of life-long disability management. Family-centred service is embraced as a 'best practice' model because of accumulating evidence supporting its positive influence on parents and children's outcomes. Nevertheless, research comparing parent and provider perspectives on family-centred practices of educational service providers in education settings is scarce.

Educational Instructors' Attitudes Toward Juvenile Inmates: The Effect of the Inmate's Role in a Criminal Event and the Instructors' Belief in a Just World.

The aim of the present study was to examine factors that affect educational instructors' attitudes toward juvenile inmates in corrective educational facilities. Educational instructors play an important role in the rehabilitation of juvenile inmates, and their attitudes may affect the adolescents' chances of rehabilitation. We adopted an ecological perspective and explored the relationship between instructors' belief in a just world (BJW) and the role of inmates in a criminal event (offender/victim).

Repetitive deep transcranial magnetic stimulation for motor symptoms in Parkinson's disease: A feasibility study.

Objectives: Repetitive transcranial magnetic stimulation (rTMS), using standard coils, provided modest symptomatic benefits in patients with Parkinson's disease (PD). In our previous exploratory studies, using the newly developed Hesed coil (providing deeper rTMS; rDTMS) high frequency (HF), excitatory rDTMS over the primary motor cortex (M1), did not achieve sufficient beneficial effect for PD symptoms, while low frequency (LF) inhibitory stimulation, was mildly beneficial. To further investigate the optimal rDTMS stimulation parameters for PD patients, and to assess whether there is an added value for dual stimulation, consisting of HF rDTMS over the prefrontal cortex (PFC) along with LF M1 rDTMS.

Small-bioreactor platform technology as a municipal wastewater additive treatment.

The bioaugmentation treatment approach presents both an economical and environmentally friendly solution for wastewater treatment. However, the use of exogenous bacterial cultures presents several limitations: negative interaction between microorganisms and adaptation to new physical and chemical composite environment. These selective forces create a significant challenge for the introduced culture to achieving the required biomass in order to conduct the target biological treatment.

Inmate harassment and rape: an exploratory study of seven maximum- and medium-security male prisons in Israel.

Prisons deprive male inmates of heterosexual relationships and thus prevent them from asserting their masculinity via "traditional" means. Accordingly, many prisoners experience extreme emotional, psychological, and physical distress, which turns several of them to intimidation, aggression, and re-establishment of their sense of dominance through homosexual activities with coerced partners. This study, based on 760 hours of phenomenological semi-structured interviews undertaken in a random sample of 1.
