PANORAMA SOBRE O ACESSO DE ESTUDANTES COM DEFICIÊNCIA EM CURSOS TÉCNICOS DA FRONTEIRA OESTE RS
Authors: Ferraz Rodrigues Anália , Fernandes de Castro Sabrina
Published: March 2024

O presente estudo objetivou analisar o acesso de estudantes com deficiência em cursos técnicos da rede pública, presentes em treze municípios da Fronteira Oeste do Rio Grande do Sul (RS). A pesquisa, quanto à sua natureza, pode ser classificada como básica, a abordagem utilizada é quanti-qualitativa e, em relação aos objetivos, é considerada exploratório-descritiva. Os procedimentos envolveram a investigação das gestões que compõem os cursos técnicos, por meio de questionários remotos criados pelo Google Forms. A análise dos dados mostrou que, na Fronteira Oeste do RS, é ofertado um total de 40 diferentes cursos técnicos em instituições públicas, onde existem 2.729 matriculados. Os estudantes com deficiência correspondem a 1,13% desse total. Dos cinco campi de institutos federais e sete escolas estaduais pesquisadas, todas as escolas sem sujeitos com deficiência matriculados eram da rede estadual. Os desafios percebidos pelos estudantes com deficiência, professores e gestão corroboram sobre a falta de profissionais de apoio e de preparo dos professores. Percebe-se a disparidade existente no número de estudantes com deficiências matriculados entre a rede federal e estadual do RS, que acabam constituindo os Institutos Federais, efetivamente, em instituições inclusivas. Considera-se de extrema importância a constituição de novas pesquisas e de políticas públicas que gerem subsídios para a permanência e conclusão do estudante com deficiência em cursos técnicos.
Acordo de Não Persecução Penal (ANPP): aspectos gerais e observações sobre a confissão extrajudicial
Authors: Schietti Cruz Rogerio , Martins Neiva Monteiro Eduardo
Published: March 2024

With the introduction of the Criminal Non-Prosecution Agreement in the criminal procedural law by L. 13.964, of 2019, the criminal consensual justice system now has yet another important institute. Although initially provided for in CNMP Resolution n. 181, of 2017, its legal provision permanently removed the criticisms directed at its implementation through an infralegal act. In addition to exploring the legal nature of the ANPP, the possibility of its application in various crimes, its relationship with the constitutional right to silence, as well as the need for the Investigated to know the evidence produced against him to better evaluate the proposed agreement, the study analyzes the extrajudicial confession as an essential requirement for its celebration and approval by the Judiciary, including the exposition of the understandings of the Federal Supreme Court and the Superior Court of Justice that are formed on the subject. In the end, in view of the researched precedents, we seek to answer the following questions: do the STF and the STJ require certain requirements to validate the extrajudicial confession? Do you understand that judicial appreciation is relevant?
Acordo de Não Persecução Penal como instrumento político-criminal: possibilidades, reconfigurações jurisprudenciais vinculantes e os novos rumos do processo penal brasileiro
Authors: Divan Gabriel Antinolfi , Araruna Santiago Nestor Eduardo
Published: March 2024

The paper, based on a bibliographic and hermeneutic review with a deductive approach, presents the configuration of the Non-Prosecution Agreement (ANPP) as a political-criminal instrument, the foundations of which need to be understood. Against the backdrop of the discussion of these foundations as binding by the Supreme Federal Court (STF), the first part advocates for the maximum scope and retroactivity of the ANPP as a mixed norm, seeking to describe the state of the discussion and the bases of the debate in jurisprudence. In a second moment, it proposes that the concept of penal insignificance, present in the legal discipline of the ANPP, should gain prominence as a critical function linked to the political-criminal analysis of jurisdictional action. In the third section, the text asserts the urgency of a justification for filtering the necessity or not of penal incidence and its convenience, based on perspectives on what may constitute just cause for criminal action. In the concluding remarks, the paper revisits the potential role of ANPP as an instrument that could inaugurate a democratic renewal in the legal system, given its ability to pave the way for a strategic discussion regarding the necessity or not of state-punitive action.

Tiny But Mighty: Unveiling the Nutritional Powerhouse of Watermelon Seeds
Authors: Labhane Ms. Aarti
Published: March 2024

Abstract: The Curcubitaceae family includes the significant horticultural crop known as watermelon (Citrulus lantus). Many researchers have demonstrated watermelon's nutraceutical potential, making it a superior option for a functional diet. Numerous illnesses, including those connected to age, obesity, diabetes, ulcers, and several kinds of cancer, have been treated with watermelon. Citruline, lycopene, and other polyphenolic substances are among the significant phytochemicals of pharmacological significance that provide watermelon its therapeutic qualities. Watermelon serves as a crucial supplier of l-citrulline, a neutralalpha amino acid that serves as a precursor to l-arginine, an essential amino acid required for the synthesis of proteins. Numerous health benefits were demonstrated in both in vitro and in vivo trials when l-citrulline and lycopene supplements were given.
Beyond the Mask: Advancements in Facial Recognition through Convolutional Neural Networks
Authors: Chowdhury Prof. Md. Mizan
Published: March 2024

Abstract: Facial recognition technology has gained immense popularity in recent years, yet challenges persist with face alterations and the widespread use of masks. Uncooperative individuals in real-world scenarios, such as video surveillance, often resort to masking, leading to a degradation in current face recognition performance. While extensive research has addressed face recognition under various conditions, the impact of masks has often been overlooked. This research focuses specifically on improving the accuracy of recognizing faces obscured by different masks. Our proposed approach involves initial detection of facial regions, addressing the occluded face detection problem through the Multi-Task Cascaded Convolutional Neural Network (MTCNN). Subsequently, facial feature extraction utilizes the Google Face Net embedding model, followed by a classification task executed by Support Vector Machine (SVM). Experimental results demonstrate the effectiveness of this approach in masked face recognition, with noteworthy performance even under excessive facial masks. Additionally, a comparative study enhances our understanding of the proposed method's capabilities

The Reveal Of Psychic Wholeness In Shobha Des Sultry Days
Authors: Ganvir Asst. Prof. Vijay S.
Published: March 2024

Abstract: This paper explores how Shobha De's writings make a concerted effort to correct antiquated ideas and replace them with new ones that would not tolerate the denigration of women but would instead elevate them as an independent creature. Women now are starting to declare their independence in real ways. Sultry Days is, thus, an existential fight of a sensitive soul against the repressive dual standards and condescending attitude adopted by the male chauvinistic society, which shapes its regulations indenting to make women always feel subservient to males. 'New Women' who are economically, emotionally, and sexually free to pursue their own goals and interests because to De's portrayal of complex female characters that are both powerful and fragile. Rather of begging for pity or lamenting her plight, Nisha works to carve out a niche for herself within the established order and is even willing to test out the many permutations of a life lived on her own terms. Her idea of liberty is neither political or economic, but rather the liberty to think and behave as one pleases. Besides highlighting women's plight, De's true and admirable goal is to steer mankind toward enlightenment by emphasizing the need of upholding moral principles
Video Transcripts Summarization using OpenAI Whisper and GPT Model
Authors: Bhargavi A D
Published: March 2024

Abstract: In today’s digital age, a vast amount of video content is generated and shared on the internet every minute. However, extracting relevant information from these videos can be time-consuming and challenging. This is where video transcript summarization comes in, providing a concise summary of video content without the need to watch the entire video. The video transcript summarization system aims to streamline the process of extracting key insights and information from video content by generating concise and informative summaries from their transcripts. In the dynamic landscape of video content, existing approaches to transcript summarization have encountered challenges that limit their effectiveness. Issues such as compromised accuracy, prolonged processing times and a restricted focus on YouTube's captioned videos have prompted the exploration of alternative solutions. This paper introduces a novel approach that tackles these limitations head-on, employing innovative technologies to redefine the landscape of video transcript summarization. To address the identified limitations, we propose an alternative strategy that hinges on the utilization of advanced technologies like OpenAI Whisper Model Automatic Speech Recognition(ASR) for video’s Transcription and Generative Pre-trained Transformer (GPT) model for Summarization. Through the integration of the OpenAI Whisper model for transcription and GPT models for summarization, our proposed approach strives to redefine standards in accuracy, processing efficiency, multilingual support, and exhibit the capability to generate either extractive or abstractive summaries. In the context of natural language processing (NLP) and text summarization ROUGE (Recall-Oriented Understudy for Gisting Evaluation) metrics will be used to evaluate the quality of generated summaries compared to human referenced summaries

Authors: Cahyadini Annisa , Isfaeni Hanum , Komala Ratna
Published: March 2024

The lecture technique still dominates in biology education, and there are not enough hands-on, interactive, creative, and problem-solving learning activities to encourage students to apply their problem-solving skills. The purpose of this study is to examine how the problem-based learning (PBL) model and students' metacognition skills affect their ability to solve environmental pollution issues. A total of 60 X MIPA students from SMA Muhammadiyah 16 Jakarta comprised the total sample of the research, collected using the quasi-experimental approach. For the study, two groups were utilized: the experimental group (X MIPA 1) and the control group (X MIPA 2). A 2 x 2 factorial design with a pretest-posttest control group was employed for the investigation. The instruments used in the study were classified as tests or non-tests. The test instrument is an essay designed to collect data on problem-solving ability and metacognition ability, while the non-test instruments are student worksheets that refer to the PBL stage, and the observation sheet is designed for instructors and students. Data analysis using ANCOVA with a significance level of 0.000 < α = 0.05 indicates that H0 was rejected. The interaction between the PBL learning model and students' metacognition skills also has an impact on their capacity to address environmental pollution-related issues.

However, in reality conflicts between employees still occur frequently. This study aims to determine the relationship between self-esteem and Schadenfreude in empoyees. The hypothesis in this study is that there is a relationship between self-esteem and Schadenfreude. The subjects in this study were employees who worked in an agency or company with an age range of 18 years and over and working for more than 1 year. Data collection techniques will use the self-esteem scale and Schadenfreude scale. The data were analyzed using pearson's correlation product moment in the SPSS version 26 software program. Based on the results of the analysis, the correlation coefficient values was -0.624 and p=0.000. (p≤0.050). These results indicate a significant negative relationship to self-esteem and Schadenfreude. The coefficient of determination R2 is 0.390, which means that self-esteem has a relationship of 39% to Schadenfreude while the remaining 61% is influenced by other factors.
Identifying Exploitable Memory Objects for Out-of-Bound Write Vulnerabilities
Authors: Li Runhao , Zhang Bin , Tang Chaojing
Published: March 2024

Exploit an out-of-bounds write vulnerability in general-purpose
applications has become a current research focus. Given the large scale
of code in programs, selecting appropriate memory objects for
exploitation is challenging. In the letter, we propose a corrupted data
propagation-guided fuzzing method. By tracking the propagation process
of corrupted data among memory objects, we propose a multi-level fuzzing
schedule to search the execution paths. Experimental results show that
our proposed method, EMOFuzz, can effectively identify exploitable
objects under various overflow lengths, significantly enhancing the
efficiency of exploitability analysis.
A data-driven approach to physics-based risk models for deep-seated landslides
Authors: Lau Rachael E , Veveakis Manolis
Published: March 2024

This study addresses the modeling of deep-seated landslides, focusing on
the El Forn landslide in Andorra, using remote sensing and data-driven
approaches to create risk maps. A temperature-based model is adjusted
with data from an instrumented borehole to determine material properties
and conditions. The calibrated model is compared to Interferometric
Synthetic Aperture Radar (InSAR) data, using the data for spatial
analysis and creating a correlation map through kriging. This map leads
to a physics-informed risk map indicating areas of instability. An
uncertainty analysis of the model highlights its limitations but
underscores the utility of such maps for policy and planning in areas
prone to landslides. This approach provides a novel tool for assessing
landslide risks, combining in-situ and remote sensing data for effective
risk management.
Microbial autotrophy recorded by carbonate dual clumped isotope disequilibrium
Authors: Ingalls Miquela , Leapaldt Hanna , Lloyd Max K
Published: March 2024

The proliferation of microbial carbon fixation is a key control on the
evolution of the biosphere and global carbon cycle. Most records of
these metabolisms in ancient rocks come from organic matter or fossils,
which are not always preserved. Here, we present a potential proxy for
microbial carbon fixation (autotrophy) based on the isotopic composition
of carbonate minerals. Autotrophs influence carbonate chemistry in the
cellular microenvironment by decreasing CO2concentration and increasing
carbonate saturation state. This can induce rapid precipitation of
carbonate minerals that are out of isotopic equilibrium with their
environment. Recent work has identified disequilibrated dual clumped
isotope compositions (∆47 and ∆48) in the skeletal fossils of marine
calcifying organisms. Here we test whether the same is true of
non-skeletal carbonate fabrics associated with microbial autotrophs in
modern and Eocene lakes. We found that microbial carbonate formed via
autotrophic metabolism recorded lower ∆47 and higher ∆48 values
(-∆47/+∆48) than predicted for thermodynamic equilibrium mineral
formation. Our findings are supported by models of dual clumped isotope
kinetics in the DIC system, and disequilibrium in the oxygen isotope
system. We hypothesize that the inverse trajectory away from the
equilibrium line (+∆47/-∆48) should be recorded by carbonates formed in
association with alkalinizing heterotrophs, such as sulfate reducers. If
so, carbonate dual clumped isotopes could be a powerful tool to identify
the proliferation and rate of heterotrophic and autotrophic metabolisms
in the carbonate rock record on Earth and (perhaps) other planets.
Moisture transformation in Arctic warm airmass intrusions: process attribution with stable water isotopes
Authors: Brunello Camilla Francesca , Gebhardt Florian , Rinke Annette , Duetsch Marina , Bucci Silvia , Meyer Hanno , Mellat Moein , Werner Martin
Published: March 2024

Warm airmass intrusions (WAIs) from the mid-latitudes significantly
impact the Arctic water budget. Here, we combine water vapor isotopes
measurements from the MOSAiC expedition, with a Lagrangian-based process
attribution diagnostic to track moisture origin and transformation in
the central Arctic Ocean during two WAIs, under contrasting sea-ice
concentrations (SIC). During winter with high SIC, two moisture states
emerge: the local in-Arctic moisture, for which the isotope signal is
influenced by kinetic processes in ice-cloud formation, is rapidly
overprinted by low-latitude moisture advected poleward during WAI. In
summer under low SIC, moisture is supplied through evaporation from land
and ocean, with moisture distillation via liquid-cloud formation. The
isotopic composition reflects the influence of higher humidity at the
evaporation sites. Given the projected increase of frequency and
duration of WAIs, our study contributes to assess process changes in the
Arctic water cycle.
Ocean bays surrounded by desert land could support photosynthetic life on Snowball Earth
Authors: Shum Greta E. M. , Laguë Marysa M. , Swann Abigail L.S. , Bitz Cecilia , Waddington Edwin D , Warren Stephen G.
Published: March 2024

Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball
Earth events, indicating that liquid-water refugia existed somewhere on
the surface. We examine the potential for refugia at the coldest time of
a snowball event, before CO had risen and with
high-albedo ice on the frozen ocean, before it became darkened by dust
deposition. We use the Community Earth System Model to simulate a
“modern” Snowball Earth (i.e., with continents in their current
configuration), in which the ocean surface has frozen to the equator as
“sea glaciers”, hundreds of meters thick, flowing like ice shelves.
Despite global mean surface temperatures below -60°C, some areas of the
land surface reach above-freezing temperatures because they are darker
than the ice-covered ocean. With low CO (10 ppm) and
land-surface albedo 0.4 (characteristic of bright sand-deserts), 0.1
percent of the land surface could host liquid water seasonally; this
increases to 12 percent for darker land of albedo 0.2, characteristic of
polar deserts. Narrow bays intruding from the ocean to these locations
(such as the modern Red Sea) could provide a water source protected from
sea-glacier invasion, where photosynthetic life could survive. The
abundance of potential refugia increases more strongly in response to
reducing the land albedo than to increasing the CO, for
the same global radiative forcing.

Comparative index and Hörmander index in finite dimension and their connections
Authors: Elyseeva Julia , Sepitka Peter , Simon-Hilscher Roman
Published: March 2024

In this paper we prove new relations between the comparative index and the
H?rmander index (and the Maslov index) in the finite dimensional case. As a
main result we derive an algebraic formula for calculating the H?rmander
index of four given Lagrangian planes as a difference of two comparative
indices involving certain transformed Lagrangian planes, or as a combination
of four comparative indices. This result is based on a generalization of the
comparison theorem for the Maslov index involving three Lagrangian paths. In
this way we contribute to the recent efforts in the literature (by Zhou, Wu,
Zhu in 2018 and by Howard in 2021) devoted to an efficient calculation of
the H?rmander index in this finite dimensional case.
New inequalities for (p,h)-convex functions for τ-measurable operators
Authors: Ighachane Mohamed , Bouchangour Mohammed
Published: March 2024

The main goal of this article is to present new inequalities for (p,
h)-convex and (p,h) log-convex functions for a non-negative
super-multiplicative and super-additive function h. Our first main result
will be h? (v/?) ? (h(1 ? v) f (a) + h(v) f (b))? ? f ? [((1 ? v)ap +
vbp) 1 p] / (h(1 ? ?) f (a) + h(?) f (b))? ? f ? [((1 ? ?)ap + ?bp)1p] ? h?
(1 ? v/1 ? ?), for the positive (p, h)-convex function f, when ? ? 1, p ?
R\{0} and 0 ? v ? ? ? 1. This gives a generalization of an important result
due to M. Sababheh [Linear Algebra Appl. 506 (2016), 588-602]. As
applications of our results, we present many inequalities for the trace, and
the symmetric norms for ?-measurable operators.
Subnormal n-th roots of matricially and spherically quasinormal pairs
Authors: Stankovic Hranislav
Published: March 2024

In a recent paper, Curto et al. [4] asked the following question: ?Let T be a
subnormal operator, and assume that T2 is quasinormal. Does it follow that T
is quasinormal??. Pietrzycki and Stochel have answered this question in the
affirmative [18] and proved an even stronger result. Namely, the authors
have showed that the subnormal n-th roots of a quasinormal operator must be
quasinormal. In the present paper, using an elementary technique, we present
a much simpler proof of this result and generalize some other results from
[4]. We also show that we can relax a condition in the definition of
matricially quasinormal n-tuples and we give a correction for one of the
results from [4]. Finally, we give sufficient conditions for the equivalence
of matricial and spherical quasinormality of T(n,n) := (Tn 1, Tn 2 ) and
matricial and spherical quasinormality of T = (T1, T2), respectively.
On the categories of probabilistic approach groups: Actions
Authors: Ahsanullah T.M.G. , Al-Thukair Fawzi , Nayar Bhamini
Published: March 2024

Starting with the category of probabilistic approach groups, we show that the
category of approach groups can be embedded into the category of
probabilistic approach groups as a bicoreflective subcategory; further,
considering a category of probabilistic topological convergence groups, we
show that the category of probabilistic topological convergence groups is
isomorphic to the category of probabilistic approach groups under so-called
triangle function ?: ?+ ? ?+ ?? ?+, where ?+ is the set of all distance
distribution functions that plays a central role for probabilistic metric
spaces. Moreover, if we allow this triangle function ? to be sup-continuous,
then we can show that the category of probabilistic metric groups can be
embedded into the category of probabilistic approach groups as a
coreflective subcategory. Furthermore, we demonstrate that every T1
probabilistic topological convergence group satisfying so-called (PM) axiom
is probabilistic metrizable. Finally, among others, introducing a category
of probabilistic approach transformation groups, we show that the category
of probabilistic topological convergence transformation groups is isomorphic
to the category of probabilistic approach transformation groups; this solves
an open problem that proposed in one of our earlier papers. Moreover, we
prove that the category of probabilistic metric transformation groups is
isomorphic to the category of probabilistic metric probabilistic convergence
transformation groups.

In this paper, we define interpolative enriched contractions of Kannan type,
Hardy-Rogers type and Matkowski type, by enriching existing interpolative
contractions, in the setting of convex metric space. For these newly
introduced contractions, we prove existence of fixed points and
approximation results using Krasnoselskij iteration. Examples are also given
to indicate the relevance of our results in comparison to some of the
existing ones in the literature.
Continuous dependence on parameters of differential inclusion using new techniques of fixed point theory
Authors: Tri Vo
Published: March 2024

In this paper, we establish the global existence and the continuous
dependence on parameters for a set solutions to a class of time-fractional
partial differential equation in the form {?/?t u(t) + KA?1 ?/?t
u(t) +A?2u(t) ? F(t, u(t), ?), t ? I, u(T) = h, (resp. u(0) = h) on ?,
where ?1, ?2 > 0 and I = [0, T) (resp. I = (0, T]). Precisely, first results
are about the global existence of mild solutions and the compactness of the
mild solutions set. These result are mainly based on some necessary
estimates derived by considering the solution representation in Hilbert
spaces. The remaining result is the continuous dependence of the solutions
set on some special parameters. The main technique used in this study
include the fixed point theory and some certain conditions of multivalued
operators.

Introduction/Objective This study evaluates the effects of hemodialysis (HD) on intraocular pressure (IOP) and ocular anterior chamber morphometry in end-stage renal disease (ESRD) patients. Methods In total, 32 ESRD patients (50 eyes) who were on regular HD program, underwent ocular examination. To all of them, 30 minutes before HD and 30 minutes after the end of the HD session, central corneal thickness (CCT), keratometric values (K1, K2), axial length (AL), anterior chamber depth (ACD), and lens thickness (LT) were measured using the Lenstar 900 Haag-Streit USA device (Haag-Streit Group, Koniz, Switzerland). IOP was measured using Goldman applanation tonometry. Results IOP before HD was 15.74 ? 3,043 while after HD it was 15.14 ? 3,07 (p = 0.125); K1 and K2 values were 43.11 ? 1.68 vs. 43.13 ? 1.73 (p = 0.688) and 43.11 ? 1.60 vs. 43.11 ? 1.66 (p = 0.158); AL increase from 23.25 ? 0.68 to 23.27 ? 0.68 in postHD (p = 0.158) as well as AL from 23.25 ? 0.68 to 23.27 ? 0.68 (p = 0.264); ACD decrease insignificantly from 3.14 ? 0.40 to 3.10 ? 0.42 (p = 0.063); mean LT before HD was 4.66 ? 0.38 while after HD it was 4.67 ? 0.36 (p = 0.290) and CCT was 563.68 ? 42.02 vs. 563.34 ? 42.26 (p = 0.777). Conclusion HD has no significant influences on ocular anterior segment structures such as on CCT, ACD, LT, AL, K values as well as IOP.

The nature of structural changes of nanosecond laser modification inside silicon is investigated. Raman spectroscopy and transmission electron microscopy measurements of cross sections of the modified channels reveal highly localized crystal deformation. Raman spectroscopy measurements prove the existence of amorphous silicon inside nanosecond laser induced modifications, and the percentage of amorphous silicon is calculated based on the Raman spectrum. For the first time, the high-resolution transmission electron microscopy images directly show the appearance of amorphous silicon inside nanosecond laser induced modifications, which corroborates the indirect measurements from Raman spectroscopy. The laser modified channel consists of a small amount of amorphous silicon embedded in a disturbed crystal structure accompanied by strain. This finding may explain the origin of the positive refractive index change associated with the written channels that may serve as optical waveguides.

N-Myristoyltransferase: A Novel Therapeutic Target for Cancer, Inflammation and Radiation Response Modifications
Authors: Kumar Raj
Published: March 2024

N-Myristoyltransferase (NMT) is a well conserved monomeric protein that catalyzes myristoyl group transfer to various target proteins carrying consensus amino acid sequence motif GXXXS/T (where ‘X’ is any amino acid). NMT mediated myristoylation promotes protein-protein and protein-membrane interactions, leading to diverse signaling including cell proliferation, carcinogenesis, inflammation and immune responses. However, inter-networking linkage between NMT over-expression and protein myristoylation under oxidative stress coupled with inflammation and carcinogenesis is completely missing and needs further investigation. Various types of tumor and cancer tissue showed significant increase in NMT expression. Therefore, inhibition of NMT expression either by using chemical NMT inhibitors or gene silencing could be a promising approach in controlling carcinogenesis. Various scientific evidence suggests that NMT mediated myristoylation promotes membrane association of some cell cycle and cell proliferation regulatory proteins and thus may contribute to cell cycle regulation and cell survival homeostasis. Several NMT inhibitors have been evaluated and tested for their probable anticancer potential. Molecular linkage between oxidative stress and carcinogenesis has been established in several studies. In this review, the authors cover the role and therapeutic potential of NMT in cancer, inflammatory disease and radiation response modulation.
Investigation of Formaldehyde Concentration in Indoor and Outdoor Air, A Systematic Review
Authors: Rostami Roohollah
Published: March 2024

Formaldehyde, commonly recognized as formalin, stands as the archetypal aldehyde, distinguished by its colorless gaseous form and acrid scent. Widespread usage and dissemination of this compound pose potential risks of dermatological and ocular irritation, respiratory ailments, genetic alterations, and carcinogenesis. This study aims to explore the concentrations of formaldehyde in both indoor and outdoor environments. The search strategy involved querying English-language articles in Google Scholar and Science Direct databases, specifically selecting those detailing formaldehyde concentrations. Ultimately, 16 articles meeting the criteria were included in the study. Results reveal that outdoor formaldehyde mean concentration reached up to 17.02 ± 11.46 ppm, while indoor level was 0.528 ± 0.527 ppm. Industrial settings exhibited the highest concentrations, with a mean of 10.73 ± 4.5 ppm. The study exposes higher formaldehyde levels in Asian countries (0.0522 ± 0.075 ppm) compared to European and North American counterparts. Additionally, concentrations displayed a tendency to rise during the summer (3.57 ± 5.03 ppm) in contrast to the winter season (3.08 ± 5.03 ppm). These findings underscore the need for heightened awareness and regulatory measures to mitigate formaldehyde exposure, especially in industrial contexts and regions with elevated concentrations.
Mismatch between Actual and Perceived Sense of Slip Detrimentally Influences Postural Stability in Older workers
Authors: A Bhattacharya
Published: March 2024

Age-associated impairment of proprioception and decreased sensitivity to underfoot pressure, may have serious problems for the elderly for their ability to “correctly” judge or perceive the degree of slipperiness, while walking on an inclined slippery surface, such as a ramp. The present study focuses on investigating the role of age-associated influences on workers’ ability to perceive surface slipperiness and its impact on postural balance and slip and fall events while negotiating a ramp. The study was carried out on 32 younger and 33 older workers. All workers’ postural balance and slip/fall events were objectively quantitated with a human motion analysis system and subjectively measured with the perceived sense of slip/fall (PSOF) tool respectively, while they walked up and down a ramp (on a level surface or 0, or at 10, 15, and 20 degrees) on 2 surface coefficient of frictions (dry: 0.76-1.06; moderately slippery: 0.19-0.21). While slip rating scores for the dry surface were comparable between the groups, the older workers significantly (p=0.046) underestimated the slippery surface. The deviation of the subjective surface slipperiness rating from the mean (DSSSR) for each surface was calculated. As expected, the older workers’ objective measure of postural balance was poorer than the younger group when they negotiated the slippery ramp surface. Repeated measure logistic regression analysis showed that the younger group was more likely to slip but much less likely to fall as DSSSR increased. Therefore, a mismatch between perception of slippery surface risk and the actual risk may jeopardize workers’ ability to safely negotiate a slippery ramp surface and thereby make them more susceptible to slip-related fall-injuries.

Authors: Kumarapeli Chandani Priyadarshika
Published: March 2024

The drug abuse in Sri Lanka is continuously grown fast and variety of new narcotic drugs comes to the market day by day. Cathine {(1S,2S)-2-amino-1-phenylpropan-1-ol} is a monoamine alkaloid found naturally in the shrub Catha edulis (Khat). It is a psychoactive drug of the phenethylamine and amphetamine chemical classes which act as a stimulant. The drug responsible for the CNS stimulating effect and it can be isolated from fresh khat leaves. Synthetic Cathinones and Cathine referred to as designer Drugs, Party drugs or club drugs. Cathine was detected recently in the Narcotic Laboratory of Government Analyst’s Department and this is the first report of finding Cathine in Sri Lanka. The white crystalline substance concealed in an envelope was delivered to the Narcotic Laboratory of Government Analyst’s Department of Sri Lanka for further analytical examination including qualitative and quantitative analysis. Preliminary colour test and secondary test including TLC, UVVisible spectroscopy, GC-MS, FTIR spectroscopy and Raman spectroscopy were performed for qualitative analysis. The results revealed that the unknown white crystalline substance contained Cathine Hydrochloride and it was found for the first time in Sri Lanka. Furthermore, GC with FID detector was carried out to find the quantification results and it revealed that the unknown substance contained nearly 23% of Cathine Hydrochloride in the sample. The tendency may be more common that most new designer drugs are prepared to circumvent existing legislation and becoming attractive to illicit drug cookers in the world.
