While urban parents possess a foundational awareness of adolescent depression and anxiety, a significant gap between their conceptual knowledge and practical communication skills creates confusion and inconsistent support. The research aims to assess the level of parents' knowledge about adolescent mental health disorders, identify the extent of their confusion regarding sudden behavioral changes, and evaluate the supportive practices they employ to help their children cope. Based on a survey of 320 parents in Dhaka, the study found a moderate-to-high level of conceptual knowledge (M = 3.66) but significant gaps in practical help-seeking and communication confidence. Parents reported moderate levels of confusion (M = 3.42), particularly in distinguishing normal adolescent development from clinical distress. While overall support was moderate (M = 3.58), a meaningful minority of parents admitted to maladaptive responses, such as shouting, criticizing, or avoiding emotional discussions. The findings suggest a "practice-action discrepancy" where conceptual awareness does not translate into effective support. There is an urgent need for parenting counselors to shift focus from general awareness to applied skills training, including emotional first aid, role-playing for difficult conversations, and providing clear pathways for professional mental health resources.

Lithium-ion batteries are an integral part of today’s society, powering ubiquitous rechargeable devices. However, only 5% of all lithium-ion batteries are recycled, resulting in 8 million tons of waste being dumped in landfills [1]. This poses a risk to the environment and requires new metal to be mined. Improving the recycling process for lithium-ion batteries can have a large impact even in small communities like Plano, where over a ton of valuable metal can be extracted from lithium-ion batteries every year. There are several methods that can be used to recycle lithium-ion batteries, but they are largely inefficient and expensive. This paper aims to outline the optimization of the efficiency of hydro-metallurgical processes to extract metal from spent lithium-ion batteries. The proposed process has three steps - filtration, chelation, and electrolysis. Filtration removes the insoluble debris from the solution, chelation will be used to remove select metals like iron from the solution, and electrolysis can be used to extract the rest of the valuable metals. The data collected from the experiment indicated that the methods used were successful in improving the efficiency of the whole extraction. However, work still needs to be done to improve the efficiency on a commercially viable scale.

Abstract The Krafla geothermal system is located within a volcanic center that periodically emit basaltic lavas, and has recently attracted an economic interest due to supercritical fluids forming nearby a shallow magma intrusion (~ 2 km depth). Here, we discuss new soil CO2 flux and stable isotope data of the CO2 efflux (δ13C) and hydrothermal calcites (δ13C, δ18O) of drill cuttings, to estimate both the current magmatic outgassing from soils and the thermal flows in the geothermal system. Soil CO2 emission is controlled by the tectonic, following the NNE-SSW fissure swarm direction and a WSW-ENE trend, and accounts for ~ 62.5 t d–1. While the δ18O of the H2O in equilibrium with deep calcites is predominantly meteoric, both the δ13C of the soil CO2 efflux and of the fluids from which calcite precipitated have a clear magmatic origin, overlapping the δ13C estimated for the Icelandic mantle (–2.5 +/- 1.1 ‰). Estimates based on the soil CO2 emission from the southern part of the system show that these fluxes might be sustained by the ascent and depressurization of supercritical fluids with a thermal energy of ~800 MW. Such significant amount of energy might reach 1.5 GW, if supercritical conditions extended below the whole investigated area. Finally, we report an increase in the soil CO2 emission of about 3 times with respect to 14 years ago, likely due to recent changes in the fluid extracted for power production or magmatic activity. Pairing the soil CO2 emission with stable isotopes of the efflux and calcite samples has important implications for both volcano monitoring and geothermal exploration, since it can help us to track magmatic fluid upflows and the associated thermal energy.

Slaughtering plants approved by the European Union have specific processes to guarantee that beef carcasses or halfcarcasses, of no less than eight months of age, are provided with health mark and then classified and identified according to the EU carcass classification grid. This classification is based on three criteria: i) Category, ii) Conformation (SEUROP) and iii) Fat Cover (FC). At the end of the classification process each carcass is given a code, consisting of two letters and a number: this operation is called Identification. The aim of our study was to evaluate how the European beef carcass quality classification is determined according to the experience of the personnel involved, then comparing the results with those yielded by the Android platform application. West Systems, through its West- Zootech division, has developed an Android platform application (SEUROP APP) that allows SEUROP and FC classification with a smart-phone. The photo taken with the smart-phone will yield the necessary angular parameters to determine the conformation class depending on the animal’s muscular mass and based on the convexity of some areas on the half-carcass. It also evaluates the ratio between surface of lean tissue and total carcass surface in order to determine the fat cover and complete the classification. The SEUROP APP was able to obtain objective measurements for as much as 84% of the assessments made during the research and development phase.

Magnetic resonance imaging (MRI) is one of the most common sources of electromagnetic (EM) fields as a diagnostic technique widely used in medicine. MRI staff during the working day is constantly exposed to static and spatially heterogeneous magnetic field. Also, moving around the MRI room to perform their functions, workers are exposed to slowly time-varying magnetic fields that induce electrical currents and fields in the body. The development of new exposure assessment methodologies to collect exposure data at a personal level using simple everyday equipment is hence necessary, also in view of future epidemiological studies. This paper describes the design and testing of a novel device for assessing personal exposure to static and time-varying magnetic fields during daily clinical practice. The dosemeter will be also used to ensure effective training of technicians who will be instructed to avoid, where possible, risk behaviour in terms of high exposure.

DOI 10.12957/dep.2011.1530 Resumen Este articulo analiza el Derecho “represivo” y “neoliberal” surgido en la ultima dictadura militar argentina, y la relacion existente entre ambos. Investiga la crisis economica y politica del Estado de sustitucion de importaciones en el tiempo inmediatamente anterior al golpe de 1976. Explica el diagnostico que la nueva elite gobernante hizo de esta crisis; diagnostico que dio lugar a la emergencia de un Derecho represivo y neoliberal. Palabras claves: Derecho-Estado-Neoliberalismo. Abstract This article analyzes the “repressive” and “neoliberal” law that appeared in Argentina during the last military government (1976-1983), and the relationship among them. It, also, analyzes the economic and political crisis of the Welfare State that took place before the military coup. It, finally, explains the diagnosis that the new military government did of this crisis; diagnosis that gave place to the emergency of a new repressive and neoliberal Law. Key words: Law-State-Neoliberalism.
