Published: April 2022

The level of environmental safety is determined by the methods and techniques used to implement them. One of the promising areas for determining the assessment of dehydrated waste used in the construction industry is biological testing, which include the use of environmentally hazardous substances, in the form of an extract, to determine the danger degree of the samples and their further use in different areas of construction.
Ensuring environmental safety in general is an important component in any industry. Solving issues of industrial safety, the use of hazardous tests in technology reveals the leading idea, which is considered in the scope of presenting the research results on the preparation and use of dehydrated waste from industrial enterprises.
It is experimentally established that liquid dehydrated wastes of galvanic production are used in the manufacture of the building materials of different complexity and subsequent use. The obtained data for construction products input and heat-treated sludge (g / dm3), masonry mortars (%) and reinforced concrete with the addition of sludge (%) is only the first stage in the construction industry. The next stage is the manufacture of more responsible products ceramic tiles with the addition of sludge (%) and asphalt with the addition of sludge (%), which requires more responsible testing i.e. under critical operating conditions.
The results of biological testing are aimed at determining the following parameters at: Dunaliella-degree of immobilization for 5 days. (%); Elodéa canadénsis - the degree of inhibition of growth in length (% to control) at exposure (d.) and Daphnia - survival at 48 days of exposure (%).
To determine the level of environmental safety of building materials obtained from dehydrated waste of galvanic production, it is possible to accurately provide an assessment of their biological condition.

Published: April 2022

This research was carried out to determine the relationship between physicochemical variables and phytoplankton community of the Eko-Nde reservoir. Changes in physicochemical parameters of aquatic ecosystems have significant impact on the species that live therein. Eko-Nde reservoir is of socio-economic significance to communities that surround it, which necessitates a proper study of the phytoplankton composition and environmental status of the reservoir. Water samples were collected from two stations in the reservoir from January 2019 to August 2019. The physicochemical parameters that were determined include but not limited to temperature, total hardness, pH and biochemical oxygen demand. The composition and diversity of phytoplankton were analyzed. A total of 2039 cells ml-1 belonging to four (4) major divisions were dominant in the order; Bacillariophyta (898 cells ml-1) > Charophyta (788 cells ml-1) > Chlorophyta (302 cells ml-1) > Cyanophyta (51 cells ml-1). Principal Component Analysis and Canonical Corresponding Analysis showed that certain physicochemical variables such as temperature, pH and total hardness were key drivers of the phytoplankton community structure of the reservoir. Diversity indices showed moderate abundance and distribution of phytoplankton species, with the highest diversity of species in the months associated with the rainy season. The appearance of pollution tolerant species such as Anabaena circinalis, Oscillatoria limosa, Nitzschia gracilis, Cymbella mexicana, Pediastrum boryanum, Synedra ulna, Cyclotella meneghiniana and Gomphonema spp. suggest that the reservoir was on the verge of pollution. Anthropogenic activities around the reservoir should be closely monitored to avoid health risks to humans and endangerment of aquatic organisms.
TRACE METAL LEVELS OF SOIL-GROWN AMARANTHS ON MUNICIPAL SOLID WASTE DRAINAGE OF WUKARI METROPOLIS
Authors: Anongo M'ember Catherine , Vincent Victor 
Published: April 2022

Soil metal levels of municipal solid waste (MSW) drainage and morphological traits of Amaranthus spp growing in the natural drainage of Wukari Metropolis was investigated as an ecological monitoring data survey and food chain contamination assessment. Selected morphological traits, physico-chemical parameters and the status of selected trace metal (Cr, Cu, Ni, Pb, Zn) levels of the municipal solid waste drainage used for dry season cultivation of Amaranthus spp were determined according to standard analytical procedures. Results reveals a significant soil Pb and Cr levels in the MSW drainage arising from traffic density fallouts. A higher soil organic matter content, slightly acidic pH and CEC of MSW drainage indicate the suitability of MSW drainage for Amaranths cultivation as reveals in the selected morphological traits which agrees with the findings of other works. This reflect high microbial activity in the compositing of MSW in the drainage. Trace metal levels were below the Joint WHO/FAO Codex Alimentarius permissible limits (Pb = 2mg/kg; Cr = 1.30mg/kg; Cu = 10mg/kg; Zn = 5mg/kg) but higher for Cr and Pb revealing the close proximity of study area to high traffic density of the Katsina –Ala – Jalingo Highway. Dry season irrigation farming of vegetables should be far from high traffic density. Natural treatment of MSW and subsequent utilization of drainages or dumpsites for dry season vegetable farming is environmentally-friendly than the application of inorganic fertilizers that pollute agricultural soils, groundwater surface waters and the soil ecosystem.

Published: April 2022

Laportea aestuans is an African herbaceous weed. This work assessed the bioactive compound content of methanol extract of Laportea aestuans leaf (LALME) and its acute and subacute toxicity effects in Male Wistar rats. According to qualitative and quantitative phytochemical analysis, LALME possesses a significant amount of phenolics, flavonoids, alkaloids, tannin, carotenoids, and anthraquinones. LALME is regarded as safe because it did not cause death in rats when given doses of up to 2,000 mg/kg body weight. LALME at 200 and 400 mg/kg markedly increased (p<0.05) serum activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transferase (GGT). There was a decrease in liver LDH activity in rats administered LALME, but no significant alteration was noticed in the serum of the rats. The total bilirubin concentration in the serum of rats given 200 mg/kg LALME and in the liver of rats administered 200 and 400 mg/kg LALME was significantly higher (p<0.05) than that in the serum and liver of control rats. The serum of rats given LALME had a nearly threefold increase in direct bilirubin compared to control. However, rats administered 200 mg/kg of LALME had an increased serum urea concentration compared to control. When comparing photomicrographs of the liver and kidney of rats given LALME to those of control rats, the liver and kidney of rats given LALME showed minor congestion and renal dissemination, respectively. In conclusion, LALME was found to be safe in acute toxicity; nevertheless, subacute administration may cause variations in

Improving In-Situ Sodium Metal Plating on Copper Foil Through Optimization of Mechanical Pressure: Towards High-Performance Anode-Free Sodium Ion Batteries
Authors: Willow Ashley , Hussein Haytham E. M. , Vajirakaphan Sutthiphan , Chasri Aphidet , Margadonna Serena 
Published: April 2022

Herein we report key developments on the scale-up of sodium ion anode free batteries through investigation of the effects of applied external pressure cell performance. Sodium ion anode free puts extra emphasis on high plating and stripping efficiency of sodium metal at the anode surface, due to the lack of an excess of the transporting ion. We demonstrate excellent Na||Cu half-cell results in coin cell configuration, and the scalability of the anode-free concept is further demonstrated, by plating and stripping of sodium metal on copper foils 10-fold larger (&gt;10 cm 2) than in other studies in coin cells (∼1 cm2). It is discovered that pressure is paramount in establishing dendrite free sodium deposition at this scale through investigating the half-cell cycling at 56–743 kPa. Achieving a low hysteresis in these large-area cells is found to only require moderate pressures (∼185 kPa). However, achieving a high cycle life required increasing the pressure to 743 kPa. It is only at these high pressures that non-dendritic sodium deposition is demonstrated due to a homogeneous plating distribution enabled by proper contact between electrodes, as confirmed by impedance measurements and optical imaging of the deposited sodium.
Subjective Experience of Antidepressant Prescription Among Adolescents With Anorexia Nervosa
Authors: Ludot-Grégoire Maude , David Vanille , Carretier Emilie , Lachal Jonathan , Moro Marie Rose , Blanchet Corinne 
Published: April 2022

IntroductionMajor depressive disorder is considered the most common comorbidity of anorexianervosa in adolescence. Some evidence argues against antidepressant use in this population. Moreover, the fear of being threatened with autonomy and of becoming dependent specific to this adolescent population and at the very core of the anorexic disease, make the proposal of such a treatment difficult to accept. This qualitative research aimed to explore the perspectives of view of adolescents with anorexia nervosa about antidepressants.MethodsWe conducted interviews with adolescents suffering from anorexia nervosa who had been treated with an antidepressant agent during their inpatient or outpatient care at Cochin Hospital. Adolescents were chosen by convenience sampling. Both verbal and written questions were asked to elicit their lived experiences. Interpretative Phenomenological Analysis was used to examine the data.ResultsFifteen adolescents (13 girls and two boys) were interviewed. We have reached total data saturation. The analysis found two meta-themes, each with two separate themes. (I) Reactions to the proposal of antidepressant with (i) an opposition phase (about the existence of depressive symptoms and about negative preconceptions) and (ii) need to share with family and other teenagers. (II) Reactions to antidepressant use with (iii) ambivalence and an initial perception of coercion, and (iv) effects of antidepressants (psychological effects, effects on the body and on anorexia nervosa and effects perceived through the eyes of others).DiscussionDespite positive effects, ambivalence toward the treatment remained present throughout the interviews: these adolescents still worry greatly about loss of control and weight gain. Depression as comorbidity seems to be entangled in the denial of disease, cognitive distortion and acquired fearlessness specific to AN. Its existence in adolescence can uncover transgenerational issues, sometimes previously hidden. An orodispersible/drinkable form of antidepressants would facilitate adherence to treatment in this specific population. The intervention of a “patient-expert” could reduce adolescents' anxiety about loss of control. A latency period seems necessary to allow them to understand the prescription at their own level and in the complexity of their anorexic illness.
