Authors: Kaur Manpreet , Dhillon Navjot Singh
Published: January 2023

Micronutrients are the necessary elements required by onion plant in small quantity to improve the yield of bulbs. It is possible to produce higher yields of good quality bulbs by judicious application of nutrients. A field experiment was conducted during spring summer, 2021-2022 at Vegetable Research Farm of Department of Agriculture, Khalsa College, Amritsar to investigate the effect of foliar application of micronutrients on yield and benefit cost ratio of onion. The experiment was laid out in Randomized Block Design (RBD) with three replications. The seven treatments are applied at 45, 60 and 75 days after transplanting. The result revealed that foliar application of micronutrients mixture outperformed from all other treatments in terms of yield and benefit cost ratio.

Dans un contexte de tension sur la ressource en eau, la répartition des usages de l’eau des rivières est réglementée pour permettre le maintien de l’équilibre écologique de nos rivières. En France, le contrôle du respect du débit minimum biologique en aval des aménagements est assuré par les agents en charge de la police de l’eau, majoritairement ceux de l’Office français de la biodiversité (OFB). INRAE est engagé depuis de nombreuses années pour accompagner l’OFB dans cette mission par des formations et la diffusion d’outils pour faciliter et améliorer la mesure du débit des cours d’eau. Cet article présente deux exemples de réalisations récentes issues de la convention OFB-INRAE 2019-2021. Le premier est la réalisation d’un essai interlaboratoire de mesures de débit par la méthode par dilution de traceur, le second est le développement et la diffusion d’un modèle de perche transparente à charge dynamique, un outil de mesure de débit à bas coût.

De nombreuses activités humaines peuvent être fortement impactées par les pénuries d'eau (production d’eau potable, irrigation, production électrique, navigation fluviale, loisirs, etc.). Il est donc nécessaire d'anticiper les périodes d'étiage afin d'améliorer la gestion de l'eau pour mieux répondre aux besoins, tout en préservant le fonctionnement des écosystèmes aquatiques. Ceci est renforcé par la perspective d'étiages futurs plus sévères dans le contexte du changement climatique en cours. Pour répondre à ces enjeux, cinq institutions françaises ont développé un outil opérationnel de prévision des bas débits, PREMHYCE. Issu d’un projet de recherche initié en 2011 et soutenu par l’Office français de la biodiversité et la Direction de l’eau et de la biodiversité, il est testé depuis 2018 en temps réel sur plus de mille bassins versants en France métropolitaine et à La Réunion. PREMHYCE comprend cinq modèles hydrologiques qui sont implémentés sur des bassins versants jaugés et assimilent les dernières observations de débits en temps réel. Les prévisions de débits sont émises quotidiennement en considérant des ensembles de scénarios de pluies et de températures (issus d’un modèle météorologique jusqu’à une échéance de 15 jours et d’archives climatiques jusqu’à une échéance de 90 jours). Les résultats de la plateforme sont communiqués aux gestionnaires opérationnels partenaires, à l’aide de supports de communication adaptés, pour les aider dans la prise de décision. Une interface web de visualisation donne une vue d’ensemble en temps réel de la situation observée et prévue.

Published: January 2023

Depuis 2017, INRAE et l’OFB développent une base de données recensant les ouvrages français de génie végétal pour la protection des berges de cours d’eau. Cette base de données est construite à la fois à destination des gestionnaires pour faire connaître les ouvrages réalisés et des chercheurs pour leur permettre de capitaliser des données pour mieux faire avancer les connaissances sur ces techniques. Cette base comporte aujourd’hui plus de mille ouvrages, mais les données présentes pour chaque ouvrage sont très hétérogènes. Cette base de données qui est partiellement disponible en ligne permet de faire un premier état des lieux de ces techniques en France en 2020. Son enrichissement doit se poursuivre ces prochaines années afin de mieux couvrir le territoire français et de fournir encore plus d’information sur les avantages et limites de ces techniques.

Un grand nombre d’opérations de restauration/création de zones humides voient le jour en France. L’efficacité de ces dernières doit être évaluée à court, moyen et long terme. C’est d’ailleurs le cas des opérations de compensation qui sont désormais soumises à obligation de résultat et doivent, pour démontrer l’efficacité de leurs opérations de restauration/création, disposer d’indicateurs robustes et facilement mobilisables. L’indicateur HYDRINDIC a ainsi été construit pour permettre le suivi et l’évaluation de l’efficacité des opérations de restauration/création de zones humides d’un point de vue hydrologique.
The Spermine Phosphate-Bound Cyclooctaoxygen Sodium Epigenetic Shell of Euchromatin DNA is Destroyed by the Epigenetic Poison Glyphosate
Authors: Kesel Andreas
Published: January 2023

Background: Oxygen exists in two gaseous (dioxygen and ozone) and six solid allotropic modifications. An additional allotropic modification of oxygen, the cyclooctaoxygen, was predicted to exist in 1990. The first synthesis and characterization of cyclooctaoxygen as its sodium crown complex, isolated in the form of three cytosine nucleoside hydrochloride complexes, was reported in 2016.Results: The sperminium hydrogen phosphate/cyclooctaoxygen sodium complex is calculated to cover the actively transcribed regions (2.6%) of bovine lymphocyte interphase genome. Cyclooctaoxygen seems to be naturally absent in hypoxia-induced highly condensed chromatin, taken as a model for eukaryotic metaphase/anaphase/early telophase mitotic chromatin. Hence, it is proposed that the cyclooctaoxygen sodium-bridged sperminium hydrogen phosphate and selenite coverage serves as an epigenetic shell of actively transcribed gene regions in eukaryotic ‘open’ euchromatin DNA. Cyclooctaoxygen sodium-bridged sperminium hydrogen selenite was calculated to serve as a marker shell component at ATG start codons in human euchromatin DNA mRNA genes, both at the translation initiation triplet and at 5'-untranslated region upstream ATGs. The total herbicide glyphosate (ROUNDUP®) and its metabolite (aminomethyl)phosphonic acid (AMPA) are proved to represent ‘epigenetic poisons’, since they both selectively destroy the cyclooctaoxygen sodium complex. This definition is of reason, since the destruction of cyclooctaoxygen is certainly sufficient to bring the protection shield of human euchromatin into collateral epigenetic collapse.Conclusions: The total herbicide glyphosate and its environmental metabolite (aminomethyl)phosphonic acid (AMPA) can be associated in vitro with catalytic detoriation of eukaryotic euchromatin genetic information.General Significance: The epigenetic shell of eukaryotic euchromatin is susceptible to decay induced by catalytic epigenetic poisons threatening eukaryotic genomic heritage.
Precision Oncology-Based Targeting of Signaling Pathways toward a Holistic Approach to Cancer Therapeutics
Authors: Kumar Manish
Published: January 2023

The mutational changes occurring in the regulatory genes responsible for the maintenance of optimal cell growth and proliferation gradually lead to cancer progression and metastasis. Furthermore, patients with the same cancer types often respond differently to different cancer therapies, indicating the need for a patient-specific treatment regimen for the disease. Precision oncology is the new field of cancer research that relies on genetic profiling of individual tumors to identify targetable alterations for custom-tailored personalized treatment of the disease. It is to rely upon the genomic study of cancer cells to get a clear picture of the prognosis and pathways involved in disease progression and to look for the means to selectively target them for a cure. This article intends to briefly explain the foundations and frontiers of precision oncology in the context of technological advances being made in this direction to assess its scope and importance in the realization of a proper cure for cancer.
A Mechanical Newton-Einstein Hybrid Gravity based on Matter-vacuum Equilibrium Mediated by Gravitons
Authors: Goyal Gaurav
Published: January 2023

There has been a disconnect between our understanding of the universe's working at the micro and macro scale - that is, disagreement between quantum mechanics (QM) and general relativity (GR). A theory of vacuum-matter equilibrium is presented from scratch to bridge this gap. It is proposed that gravitons are both quanta of matter and gravitation, as every matter entity is believed to interact with gravitation. The vacuum has an energy density that gives rise to virtual-graviton pairs. Upon collision, a virtual-graviton may get stuck to the matter while a graviton from the matter gets ejected. It is possible as all gravitons are identical in mass and size. Equilibrium is thus established where matter erodes in the vacuum, and the vacuum condenses as matter. The probability of graviton exchange depends on the relative energies of the virtual-graviton and matter entity, as calculated in the inertial frame of reference (IFoR) decided by the state motion of vacuum energy at that place. If the rate of matter-vacuum equilibrium is taken as a constant, it leads to the notion of time and time dilation. The force appearing on a matter entity through collision with virtual-gravitons is calculated, and the expression is a hybrid of Newton's and Einstein's equation. It further helps to answer the queries related to phenomena like the flatness of galaxy rotation curves, misconceptions about relativistic mass and length contraction, the relation between time, gravity, and quantum entanglement (QE), and the composite nature of the universal gravitational constant.
A Quantum-Classical Model of Brain Dynamics
Authors: Sergi Alessandro , Messina Antonino , Hanna Gabriel , Vicario Carmelo M. , Martino Gabriella
Published: January 2023

In this article, we posit an approach to study brain processesnby means of the quantum-classical dynamics of a Mixed Weyl symbol. The Mixed Weyl symbol is used to describe brain processes at the microscopic level and, when averaged over an appropriate ensemble, provides a link to the results of measurements made at the mesoscopic scale. The approach incorporates features of three well-known approaches (which are also reviewed in this paper), namely the electromagnetic field theory of the brain, orchestrated objective reduction theory, and the dissipative quantum model of the brain. Within this approach, quantum variables (such as nuclear and electron spins, dipolar particles, electron excited states, and tunnelling degrees of freedom) may be represented by spinors while the electromagnetic fields and phonon modes involved in the processes are treated either classically or semiclassicaly, by also considering quantum zero-point fluctuations. In the proposed computation scheme, zero-point quantum effects can be incorporated into numerical simulations by controlling the temperature of each field mode via coupling to a dedicated Nosè-Hoover chain thermostat. The temperature of each thermostat is chosen in order to reproduce quantum statistics in the canonical ensemble. Viewing the brain in terms of QC processes has consequences on the theory of clinical psychology and potential implications for its practice.

Authors: Terra Stela , Tonetto Mirela , Franz Luis Antonio , Amaral Fernando
Published: January 2023

The adoption of harmful postures due to a sedentary lifestyle, which involves long periods at work in offices, is a factor that exacerbates musculoskeletal risks. To examine these risks, there are numerous postures analysis methods, such as Rapid Upper Limb Assessment (RULA) and Rapid Office Strain Assessment (ROSA). RULA is a consolidated method to evaluate the exposure of individual workers to ergonomic risk factors associated with upper extremity musculoskeletal disorders. In turn, ROSA is a more recent method that quantifies exposure to risk factors in an office work environment. This research aims to identify whether there is harmony between these two methods, ROSA and RULA. Through applied research, from a qualitative perspective, the scientific procedures adopted were direct observation and ROSA and RULA postural assessment instruments. The study was conducted in the radiology service and focused on the outpatient reception workstation. Results indicated that further investigation must occur to make working conditions changes as soon as possible and that both methods are harmonic. As contributions of the analysis, we have discussed the working conditions and suggested improvements to reduce the risks of musculoskeletal morbidity symptoms. We recommend future studies aimed at measuring the levels of complementarity between these methods by quantitative approaches.

To build a stable power factor and high output accuracy, it should use balanced active and reactive power, also used ultrasonic PWM was used with the frequencies (20–500 kHz). I also used a three-phase dynamic load at the output system and was connected to the compound splicing (CS) system this is a novelty. An oscillator circuit with 4Ghz as a microcontroller is a novelty, and designing ADC is utilized to increase accuracy, as well as contribute to the reduction of loss brought on by the characteristics of voltage source inverters (VSI), such as dead time determined by the excess voltage or voltage drop in the inverter, circumstances abnormal to the load current, such as short circuit current in the production phase, and so forth. The innovation relates to the inverter's load sensing circuit, current smoothing during operation, reaction, spontaneous power factor enhancement of the inverter, and correction of reactive power of passive devices. This invention contributes to the advancement of D.C to A.C power converter by the achievement of extremely low losses, excellent precision, and lightweight construction. Additionally, the accuracy ranges from 99%, and the total harmonic distortion (THD) of the voltage and current is (0.1%-0.8%). We Power MOSFET are used, along with FPGA to improve control over the creation of ultrasonic PWM signals, the programmable peripheral interface (PPI) 8255A for regulatory work. The marks serve as proof of this.

Published: January 2023

The risk of 'zoonotic spillovers,' or the transmission of viruses from animals to humans, has been raised by climate change and the devastation of nature, as infectious disease experts have long warned. Even as the world works to stop the spread of the currently unfolding pandemic of coronavirus disease 2019 (COVID-19) and the breakout of monkeypox virus (MPXV), a new animal virus, the Langya henipavirus (LayV), has been discovered in humans in Eastern China. The scientists say there is little danger of the virus spreading among humans, but it shares genetic material with Hendra virus and Nipah virus, two other henipaviruses that infect humans and cause life-threatening respiratory diseases. Humans infected with LayV can expect to experience high body temperature, cough, weariness, poor appetite, muscle discomfort, myalgia, nausea and vomiting. It is likely that the virus will spread from animals to humans. Currently, the health authorities of Taiwan and other health organizations are tracking the progress of the ailment to ensure it does not reach humans. Researchers have examined 25 species of small wild animals for presence of the virus, and so far, shrews are the only ones that have tested positive for the virus's RNA. Based on these results, shrews are a possible candidate for the virus's natural reservoir. Too far, no therapies or vaccines have been developed and licensed for henipaviruses like the LayV. When other therapies fail to alleviate viral infections, ribavirin may be the next best thing. The need for novel vaccinations against the LayV infection and the timely delivery of these vaccines to areas at high epidemiological risk is real. To lessen the likelihood of a health calamity being caused by this newly developing virus, it is crucial to conduct active surveillance in a transparent and globally collaborative manner. The questions that have not been answered yet require additional study.
Genetic Risk Scores and Missing Heritability in Ovarian Cancer
Authors: Brody James P , Fatapour Yasaman
Published: January 2023

Ovarian cancers are curable by surgical resection when discovered early enough. Unfortunately, most ovarian cancers are diagnosed in the later stages. One strategy to identify early ovarian tumors is to screen women who have the highest risk scores. This mini review summarizes the accuracy of different methods used to assess the risk of developing ovarian cancer, including family history, BRCA genetic tests, and polygenic risk scores. The accuracy of these is compared to the maximum theoretical accuracy, revealing a substantial gap. We suggest that this gap, or missing heritability, could be caused by epistatic interactions between genes. An alternative approach to computing genetic risk scores, using chromosomal-scale length variation should incorporate epistatic interactions. Future research in this area should focus on this and other alternative methods of characterizing genomes.

Published: January 2023

From the standpoint of Neoliberal Institutionalism, this study explores Malaysia's participation in activities that make energy the topic and/or object of foreign policies, whether through bilateral or multilateral engagements. This research, which aims to evaluate the relevance of energy in Malaysia's economy and diplomacy and to explain Malaysia's reason for its involvement in these cooperations, is necessary because of Malaysia's growing involvement in the global energy market. Information for this study was gathered from a variety of government sources, interviews, published statistical data, and previous studies. The study demonstrates how vital energy is to Malaysia's economy. The Lao PDR-Thailand-Malaysia-Singapore Power Integration Project (LTMS-PIP) initiative, in which Malaysia is participating, is evidence of the viability of multilateral power commerce in the area. The Peninsula Gas Utilisation (PGU) pipeline in Peninsular Malaysia and the Four-Fuel Diversification Policy 1981 (4FDP 1981), which increases natural gas utilisation, are related to Malaysia's participation in the Malaysia-Thailand Joint Development Area (MT-JDA). Malaysia would want to think about streamlining its energy administration.
Feasibility Study on Utilization of the Artificial Intelligence GPT-3 in Public Health
Authors: Jungwirth David , Haluza Daniela
Published: January 2023

Artificial intelligence (AI) has the potential to revolutionize research by automating data analysis, generating new insights, and supporting the discovery of new knowledge. The top 10 contribution areas of AI towards public health were gathered in this feasibility study. We utilized the “text-davinci-003” model of GPT-3, using OpenAI playground default parameters. The model was trained with the largest training dataset any AI had, limited to a cut-off date in 2021. This study aimed to test the ability of GPT-3 to advance public health and to explore the feasibility of using AI as scientific co-author. The AI was asked for input including scientific quotations and the human authors reviewed responses for plausibility. We found that GPT-3 was able to assemble, summarize, and generate plausible text blocks relevant for public health concerns, elucidating valuable areas of application for itself. However, most quotations were invented by GPT-3 and thus, invalid. Ac-cording to today’s rules, we conclude that AI can contribute to public health research as a team member. Nevertheless, good scientific practice needs to be also followed for AI contributions, and a broad scientific discourse on AI contributions is needed. Policies for good scientific practice should be updated timely following this discourse.

Published: January 2023

The development of autonomous vehicles is becoming increasingly popular and gathering real world data is considered a valuable task. Many datasets have been published recently in the autonomous vehicle sector, with synthetic datasets gaining particular interest due to availability and cost. For a real implementation and correct evaluation of vehicles at higher levels of autonomy it is also necessary to consider human interaction, which is precisely something that lacks in existing datasets. In this article the UPCT dataset is presented, a public dataset containing high quality, multimodal data obtained using state of the art sensors and equipment installed onboard the UPCT’s CICar autonomous vehicle. The dataset includes data from a variety of perception sensors including 3D LiDAR, cameras, IMU, GPS, encoders, as well as driver biometric data and driver behaviour questionnaires. In addition to the dataset, the software developed for data synchronisation and processing has been made available. The quality of the dataset was validated using an end-to-end neural network model with multiple inputs to obtain speed and steering wheel angle and obtained very promising results.
Potential Future Alternative Resources for Rare Earth Elements: Opportunities and Challenges
Authors: Vysetti Balaram
Published: January 2023

Currently, there is increasing industrial demand for rare earth elements (REE) as these elements are now integral to the manufacture of many carbon-neutral technologies. The depleting REE ores and increasing mining costs are prompting to look for alternative sources for these valuable metals, particularly from waste streams. Although REE concentrations in most of the alternate resources are lower than current REE ores, some sources such as marine sediments, coal ash, and industrial wastes like red mud are looking promising with significant concentrations of REE in them. This review focuses on the alternative resources for REE such as ocean bottom sediments, continental shelf sediments, river sediments, stream sediments, lake sediments, phosphorites deposits, industrial waste products like red mud, and phosphogypsum, coal, coal fly ash, and related materials, waste rock sources from old and closed mines, acid mine drainage, and recycling of e-waste. Possible future Moon exploration and mining for REE and other valuable minerals are also discussed. It is evident that REE extractions from both primary and secondary ores alone are not adequate to meet the current demand, and sustainable REE recovery from the alternative resources described here is also necessary to meet the growing REE demand. An attempt is made to identify the potential of these alternative resources and sustainability challenges, benefits, and possible environmental hazards to meet the growing challenges in meeting the future REE requirements.

Published: January 2023

In the era of big data with increasingly complex data structures and ever-larger data scales, matrix-type data are becoming highly valued and their applications in the fields of medicine, industry, education, geography, and astronomy are growing in extent. In recent years, significant progress has been made in the practical use of matrix variable t-distribution finite mixture models for handling data in order to address the issues of multi-subgroup structures and long data tails. In this paper, the expectation-maximization (EM) algorithm with penalized maximum likelihood is proposed to resolve the problem of the unbounded nature of the likelihood function applied to the model by considering the degeneracy of the variance-covariance matrix of this model. Our data were analyzed through simulations and real data, and the results demonstrate that our model is effective in both preventing the likelihood function from being unbounded and in ensuring the accuracy of the estimated parameters of the EM algorithm.

Published: January 2023

: The paper presents the results of uniaxial tensile tests of samples of hypoeutectic aluminum-silicon alloy A319. According to the results of which the influence of surface treatment by a pulsed electron beam on the mechanical properties of the material was determined. The peculiarities of localization of deformation in the material, caused by grinding of the surface layer material structure due to rapid crystallization during electron beam treatment were revealed. The surface treatment up to 100 µm depth leads to the formation of a fine dendritic columnar structure of silumin and to an increase in the plasticity of the samples. The influence of surface treatment affects the increase of deformation localization in the region of stable concentrator before failure. The largest increase in ductility and localization of deformation occurs during processing with energy density of 15 J/cm2. In the process of specimen deformation, unstable, metastable, and stable areas of plastic deformation localization are formed and replaced, and the formation of stable areas of localized plastic deformation, in which the specimen fails at the end of the test, can be detected at the initial stages of testing. In specimens, during testing in the zone of localized plastic deformation, bands are formed that pass through the entire surface of the specimen at an angle from 35 to 55 degrees to the axis of tension, their evolution leads to the formation of stable zones of localized plastic deformation and to the failure of the specimen.

No construction work has the same progress—various factors as the cause of inequality. A positive progress deviation indicates good construction work. Otherwise, it is said to be bad if it has a negative value. The uncertain nature of the construction work causes 3 (three) possible scenarios of the value of the deviation of progress so that the three values ​​form one value of the deviation of the expected progress. Deviations of value greater than 10% for a duration from 0 to 70% are categorized as binding contracts. This study aims to determine the deviation of the progress of 25 construction works. The research method was quantitative. Data collection was carried out on 25 construction works that had been carried out. Data was taken from contractors directly. The results of the data analysis show that when 25%D is obtained, 10 poor-performing construction jobs, Next for 30%D construction work. 50%D and 70%D underperformed 9, respectively; 9; and 8. The largest positive progress deviation value is 15,362 at S70%D. The expected value of the largest progress deviation is positive 1.763. By knowing the value of negative progress expectations, contractors should control delays before the contract is completed.

Online motorcycle taxis are a type of transportation that is widely used to support daily activities. The purpose of this study is to analyze what factors are considered in choosing an online motorcycle taxi. The method used is to form a linear regression equation model with four variables, including ease of use (X1), tariff (X2), security (X3), and efficiency (X4). The results obtained from the research equation model Y = 6.682 + 1.469 X1 + 0.456 X2 + 0.773 X3 + 0.945 X4. The results of the test for the coefficient of determination (R) are 52.6%, the choice of online motorcycle taxis is influenced by these variables. The F test shows F count (26.396) > F table (2.699), meaning that the independent variable X has a significant effect simultaneously on variable Y. The t test shows t count values X1 (3.432), X2 (2.425), and X4 (3.201) > from t table (1.98498), meaning that these variables have a partial effect on Y. Meanwhile, t count X3 (1.520) < t table (1.98498), then variable X3 has no partial effect on Y.

The availability of water in irrigation areas can affect agricultural productivity. Water balance must be maintained so that there is no shortage of water. Cikunten II has an area of 4.362 ha, mostly in the Tasikmalaya district. This study aims to analyze the water requirement and balance. Data analysis used the KP01 guidelines and the Cropwat program. The data analysis results obtained differences in reference plants' evapotranspiration results using the Modified Penman method in KP and Pennman–Monteith in the Cropwat program. The difference between the two methods is 133,83% due to the difference in albedo coefficients. The effective rainfall for paddy and secondary crops, the KP method analysis is lower than the Cropwat simulation of 110.10%. Availability of water using data from the Ciwulan weir with a reliability of 80% obtained a maximum discharge of 2,73 m3/sec. The water requirement was calculated during planting periods I, II, and II. The KP method is greater than the Cropwat method with a percentage of 277.42% in analyzing water requirements in the Paddy-Paddy-plants cropping pattern. The availability of water in the Cikunten area using Cropwat has fulfilled the needs marked by a more stable k factor than the KP01 method.

In the watershed, if there are no adequate maintenance alternatives for the morphology of the river, both the river infrastructure and the river itself can result in physical and functional degradation so that the effectiveness of the river as a natural airflow will be disrupted, flow control will not be optimal as experienced by the Amandit Kandangan River. The method to the Guidelines for the Implementation of River Infrastructure Operations Activities and River Maintenance (SE DJSDA No. 05/SE/D/2016). At STA 3+000 s.d. 6+500 is a segment with a decreased performance value of around 76.48, compared to the initial section of the range of 80.29 and the final section of the range of 80.28. This shows a decrease in the performance of the river in the middle of the sections due to airflow obstructions such as goods/materials in the troughs or bends in the river accompanied by narrowing in the middle section of the sections and often causes overflow due to the solubility of the airflow. Recommendations given are based on the results of an assessment of the overall morphological condition of the river, with the acquisition of an index in the sufficient category and the type of preventive maintenance.

Introduction. Social stigma towards mental illnesses provokes discrimination and exclusion. It is important to detect this stigma for its evaluation to establish intervention strategies that respond to needs. Objective. This study has the objective of ascertaining levels of stigma among students from the University of Burgos (UBU) towards people with mental health problems at various university faculties and to analyze the right response in each case. Results. The study involved the administration of the Questionnaire on Community Attitudes towards Mental Illness (CAMI) to a sample of 268 students from 7 educational faculties (Sciences, Health Sciences, Economics, Law, Education, Huma- nities and the Higher Polytechnic School). The results showed that the stigma of university students was influenced by different sociodemographic variables (sex, age, studies and contact with people with mental illness). Conclusions. University students who participated in the study have elevated stigmatizing attitudes towards mental health pro- blems. Direct contact with people with mental health problems prompted less stigmatizing attitudes and, in general, men held the most discriminatory attitudes. Educational interventions must be designed for this population group to reduce stigma and so that stigmatizing attitudes are no longer obstacles to professional and social development.
Biomass carbon emissions from nickel mining have significant implications for climate action

Global nickel demand is projected to double by 2050 to support low-carbon technologies and renewable energy production. However, biomass carbon emissions from clearing vegetation for nickel mining are rarely included in corporate sustainability reports or considered in sourcing decisions. Here, we compiled new data for 481 nickel mines and undeveloped deposits to show that the footprint of nickel mining is approximately 5 to 500 times greater than previously reported (depending on the mine site), and thus the environmental impacts of nickel products, including batteries, have been greatly underestimated. We found large variation in biomass losses among mines, and, in many cases, these unaccounted carbon emissions were significant relative to other Scope 1 and Scope 2 emissions from nickel extraction and processing. Reporting emissions from biomass losses from mining is key for strategic decision making on where to source the nickel needed for effective climate action.
