Published: May 2023

Knowledge of individual age can help both in-situ and ex-situ
conservation programs to design more efficient and suitable management
plans for targeted wildlife species. DNA methylation is one of the
epigenetic aging markers that has emerged as a promising tool that can
estimate age with high accuracy using only a tiny amount of biological
material, which can be collected in a minimally invasive way. Although
the conservation of Felidae species has received great attention,
studies rarely focus on the development of age estimation models. Here,
we sequenced five genetic regions and used 4–25 selected CpG sites to
build age estimation models with several machine learning methods, using
blood samples of seven Felidae species—ranging from small to big, and
domestic to endangered species: domestic cats (Felis catus, 139
samples), Tsushima leopard cats (Prionailurus bengalensis
euptilurus, 84 samples), and five Panthera species (96 samples).
The models built achieved satisfactory accuracy—the mean absolute
deviation of the best models was 1.80, 1.30, and 1.55 years in domestic
cats, Tsushima leopard cats, and Panthera spp., respectively. Our
models in domestic cats and Tsushima leopard cats were applicable to all
individuals regardless of health conditions and sex, indicating high
applicability of our models to samples collected from diverse
situations, e.g., rescued individuals in the context of conservation. We
also showed the possibility of developing universal age estimation
models for the five Panthera spp. using two of the five genetic
regions, suggesting an even lower cost to use our models for future
applications.

Published: May 2023

Objective - To analyze the effectiveness of minimal stimulation
protocol of IVF treatment for patients with severe diminished ovarian
reserve (DOR), especially for whom failed with several cycles of
conventional stimulation IVF protocols previously. Design,
setting and sample– A single center retrospective cohort
study of undergoing IVF during January 1st, 2005 to December 31st, 2021.
A total of 1,111 conventional stimulation cycles and 14,139 cycles of
minimal stimulation IVF cycles were analyzed. Methods - Women
who had undergone minimal stimulation protocol for IVF treatment and who
met the study design were admitted to the study. Patients who met the
study design undergone conventional stimulation IVF cycles were also
included as control. Basic characteristics and clinical outcomes were
all recorded and matched for the analysis of the effectiveness of
minimal stimulation IVF treatment. Main Outcome Measures – The
number of oocytes retrieved, the number of embryos obtained and
gonadotrophin stimulation dosage, stimulation days and clinical
pregnancy rates were analyzed. Results - In 16 years, a total
of 14,139 cycles of minimal stimulation IVF cycles were included into
this study in order to compare the effectiveness of the minimal
stimulation cycles and the conventional stimulation cycles. Although a
smaller number of oocytes was retrieved in the minimal stimulation
cycles compared with the conventional stimulation cycles (1.39 vs 2.26,
p<0.05), the similar pregnancy rates were obtained in both
groups (16.93% vs 18.99%). There were also no differences in live
birth and miscarriage rates in the minimal stimulation cycles compared
with the conventional cycles. Further analysis indicates that the
clinical outcomes were reduced significantly after two cycles of
conventional stimulation cycles with high dosage of gonadotropins in
those women with DOR. Conclusion- Cumulative minimal
stimulation IVF treatment is an effective alternative for women with
severe DOR. If a woman with DOR is seeking fertility treatment, it is
wise to turn to minimal stimulation protocol after no more than two
cycles of the conventional stimulation.
Cymbidium kanran can deceptively attract Apis cerana for free pollination by releasing specialized volatile compounds
Authors: Luo Huolin , Xiao Hanwen , wu xinchen , Liu Nannan , Chen Xinghui , Xiong Dongjin , Huang Weichang , Yang Boyun
Published: May 2023

Abstract: Pollination is a crucial aspect of plant reproduction and
evolution. To explore the pollination biology of Cymbidium kanran,
detailed studies were conducted on its flowering phenology, breeding
system, volatile components of flowers, and the behavior of pollinating
insects. The results showed that: 1) C. kanran does not have
self-pollination or apomixis and requires a pollination medium to
produce seeds. However, the natural fruit set rate is much lower than
that of artificial pollination, indicating a serious pollination
limitation. 2) The effective pollinating insect for C. kanran is Apis
cerana, which carries both the pollinia and anther cap during
pollination. C. kanran does not provide any reward such as nectar or
edible pollen to the pollinators. 3) The glass cylinder experiment
showed that the flower color of C. kanran is not attractive to
pollinators (p=0.1341>0.05), while the scent is
significantly attractive (p=0.00040.017<0.05), although the
color of C. kanran is one of the most diverse species within the
Cymbidium genus. 4) Based on the dynamic changes of volatile components
of flowers during different flowering periods, it is speculated that
hexanal, heptanal, octanal, 2-pentyl furan, 4-methyl-2-pentanone, and
1,4-cyclooctadiene may be the volatile components that attract
pollinators. 5) The population size, number of flowering individuals,
number of flowers, and the movement of pollinia have a highly
significant positive correlation, but the population size is not
correlated with individual reproductive success
(p=0.112~0.185>0.05). This study provides
scientific basis for the wild resources conservation and breeding in C.
kanran.
Ionospheric scintillation characteristics and their effects over GNSS signal and position and navigation systems in the Brazilian region
Authors: De Paula Eurico Rodrigues , Moraes Alison de Oliveira , Monico João Francisco Galera
Published: May 2023

The ionosphere is an ionized layer extending from about 50 km to 1,000 km of altitude. When an electromagnetic signal cross this layer it suffers a delay in its group velocity and an advance in its phase velocity. The ionosphere is very dynamics and after the sunset its F region equatorial bottomside is lifted up by the intensified eastward electric field, giving origin to an steep plasma gradient. This configurates an unstable condition with higher density plasma standing over lower density one. This instability pushes rarified plasma upward giving origin to large regions named Equatorial Plasma Bubbles (EPB) that rise at equatorial regions and map to low latitudes along the magnetic field lines and can reach continental extension. Through cascating process small scale irregularities (cm to km) are generated inside the EPBs. Due to refractive effects amplitude and phase scintillations are generated in the signal crossing these irregularities. Trans-ionospheric signals used in telecommunication links and in the GNSS applications are severely affected during ionospheric scintillations. In this work we will present the ionospheric scintillation morphology over Brazilian longitudinal sector, its effects over positioning and navigation systems and the existing methodology to mitigate them.

The selection of contractors for the project is one of the important tasks faced by the client such as developers and government agencies. To ensure that the client has selected a reliable contractor which has a good previous record, the Construction Industry Development Board (CIDB) Malaysia has established one program named SCORE by assessing seven (7) scopes of assessment which are business performance, financial capability, technical capability, project management, procurement management, best practices, and management ability. Thus, this study was done to assess the level of capability and adaptability of Malaysian contractors in the business management aspect (Scope 1). This study adopted a mixed methodology involving quantitative through secondary data and qualitative research methods through interviews. The data collected for this study is through secondary data from CIDB’S database which cover from the year 2017 until 2021. Besides that, a series of interview sessions were done to find out further suggestions for the improvement of Malaysian contractors. The findings have shown that business performance among Malaysian contractors is one of the lowest scores as compared to other scopes. Thus, this study has proposed several suggestions to increase the performance of Malaysian contractors, especially in business performance such as holding awareness programs and coaching programs.

Published: May 2023

Firms often face significant challenges to stay competitive in the present economic environment, thus, dynamic capabilities are vital as it is a substantial factor in accomplishing better business performance. This study involved yearly data of 62 firms in the ACE market that engaged with dynamic capabilities, the data was collected from the year 2012-2021. The data was gathered from the firm's annual report and has been analyzed using two-step GMM. Generally, the ACE market is consistently associated with inferior performance and capital compared to the main market. Hence, the market has the possibility of being delisted and affecting capital market performance. Therefore, this study includes dynamic capabilities in the ACE market to study the market’s performance. The results obtained are consistent with the theory, whereby changes in dynamic capabilities contributed to a positive return on the firm’s performance. However, the small capital nature of the ACE Market limits the investment in the dynamic capabilities. This study concluded that more priority to be given to the awareness of dynamic capabilities in the current competitive era. The result proved that the investment in the dynamic capabilities improved the performance of the Ace market even though some of the firms in the ACE market ignored dynamic capabilities due to capital constraints. Thus, policymakers should play their role in providing grants for the firms in the ACE Market to improve the investment in dynamic capabilities.

Published: May 2023

Despite the fact that contemporary insurance contracts are simple to read, this does not imply that they are simple to comprehend. Most people rely on trust when purchasing insurance. They trust the insurance agent to recommend and obtain appropriate coverage. Takaful agents act as consumers' representatives in managing their takaful plan participation procedures, while also providing consumers with transparent and clear information about takaful plans. This study is mainly focused on identifying the factors influencing ethical behavioral intention among takaful agents. Therefore, this study examines the relationship between attitude, subjective norms and perceived behavioral control on ethical behavioral intention among insurance agents by adopting the Theory of Planned Behaviour (TPB). A total of 100 questionnaires were collected from 100 Takaful agents from the Family agency and General Agency. To evaluate the raw data, the paper used the non-probability sampling technique and analyzed it by conducting reliability analysis, correlation analysis, and regression analysis. The results of this study indicated that there was a significant relationship between attitude and subjective norms toward ethical behavioral intention as the predictors. Hence, these findings assist the practitioners, particularly takaful providers in strategizing their efforts in terms of training aspects for their respective takaful agents.

Published: May 2023

Cybersecurity threats are a serious issue faced by many organizations in this new information era. Therefore, security leaders play a significant role not only to ensure that all their employees are practicing good security behavior to protect organizational information assets but also to ensure that security technology has been installed properly to protect network infrastructure. This study aims to examine cybersecurity protective behavior (CPB) among employees in the organization and focus on the role of leadership competencies and information security countermeasure awareness. The questionnaires were distributed via email and self-administered, and the study managed to obtain 245 responses. Partial Least Squares-Structural Equation Modeling (PLS-SEM) analysis was used to analyze the final data. Confirmatory factor analysis (CFA) testing shows that all the measurement items of each construct were adequate in their validity individually based on their factor loading value. Moreover, each construct is valid based on its parameter estimates and statistical significance. The research findings show that Procedural Information Security Countermeasure (PCM) awareness strongly influences CPB compared to a leader's information security competencies (ISI). Meanwhile, ISI significantly influences PCM awareness. This study adapts the theory of leadership competencies in the context of cybersecurity, which is particularly beneficial to any industry in improving organizational information security strategic plans.

Published: May 2023

Introduction. The lungs are one of the most common sites of metastases from
carcinomas and sarcomas. Secondary pulmonary tumors are typically multiple,
oval in shape and located in the lung periphery. Cavitation of metastatic
pulmonary nodules is extremely rare and most often occurs in primary
squamous cell carcinomas of the head and neck and the cervix. Case Report.
We report the case of a 62-year-old man presenting with dysphagia for solid
foods and weight loss in the last two months. The patient had a history of
long-term smoking and regular alcohol consumption. A barium meal showed
irregular stricture in the proximal esophagus, highly suspicious of
malignancy. Computed tomography of the neck and thorax showed tumor
infiltration of the cervical and proximal part of the thoracic esophagus and
multiple cavitary and solid pulmonary metastases. Conclusion.
High-resolution computed tomography of the chest and radiological features
such as a wall nodules, irregular internal contour of the cavity and
spiculated edges allow precise characterization of cavitary metastatic
lesions.

Introduction. Pityriasis lichenoides et varioliformis acuta is a rare
inflammatory skin disease of unknown etiology and its diagnosis is sometimes
established by eliminating diseases that are considered in the differential
diagnosis. Given the lack of randomized clinical trials, recommendations for
therapy remain based on case reports and case series. Case Report. We
present a 63-year-old female patient with generalized skin lesions
including, papules, papulonecrotic lesions, and atrophic scars accompanied
by a subjective feeling of itching that occurred 2 months before admission.
The histopathological findings showed a mixed perivascular inflammatory
cellular infiltrate and capillary blood vessels with thickened walls in the
superficial part of the dermis as signs of vasculitis. The infiltrate was
dominated by lymphocytes, neutrophils were admixed, but there were no signs
of cellular atypia, which supported the clinical diagnosis of pityriasis
lichenoides et varioliformis acuta. Therapy with systemic corticosteroids
and doxycycline was applied, which led to the resolution of lesions.
Conclusion. The authors would like to bring to the readers? attention a rare
skin disease, pityriasis lichenoides et varioliformis acuta, point to
papulonecrotic tuberculids in differential diagnosis due to similar clinical
presentation, remind them of the dilemmas that may arise in case of the
described lymphocytic vasculitis based on the findings of histopathological
analysis, and highlight the effectiveness of doxycycline and prednisone in
the therapy.

Published: May 2023

Background: Immunoglobulin A nephropathy (IgAN) is the most prevalent form of glomerulonephritis worldwide. Prediction of disease progression in IgAN can help to provide individualized treatment based on accurate risk stratification. Methods: We performed proton nuclear magnetic resonance-based metabolomics analyses of serum and urine samples from healthy controls, non-progressor (NP), and progressor (P) groups to identify metabolic profiles of IgAN disease progression. Metabolites that were significantly different between the NP and P groups were selected for pathway analysis. Subsequently, we analyzed multivariate area under the receiver operating characteristic (ROC) curves to evaluate the predictive power of metabolites associated with IgAN progression. Results: We observed several distinct metabolic fingerprints of the P group involving the following metabolic pathways: glycolipid metabolism; valine, leucine, and isoleucine biosynthesis; aminoacyl-transfer RNA biosynthesis; glycine, serine, and threonine metabolism; and glyoxylate and dicarboxylate metabolism. In multivariate ROC analyses, the combinations of serum glycerol, threonine, and proteinuria (area under the curve [AUC], 0.923; 95% confidence interval [CI], 0.667–1.000) and of urinary leucine, valine, and proteinuria (AUC, 0.912; 95% CI, 0.667–1.000) showed the highest discriminatory ability to predict IgAN disease progression. Conclusion: This study identified serum and urine metabolites profiles that can aid in the identification of progressive IgAN and proposed perturbed metabolic pathways associated with the identified metabolites.

Published: May 2023

Sea transportation experiences risks and material loss in its operation. The most significant risks include damage to the vessel and sea pollution due to ship collisions and accidents. The carrier should prioritize the risks. When the underwriter does not cover the risk, the shipowner should establish an association covering the loss among the members to the extent the underwriter does not cover it. This study will examine the importance of the Rule to P&I Clubs and its impact on Indonesian carriers and will also find the differences between P&I Club and Insurance. The research adopts Library Resarch Method, dogmatic legal approach, a descriptive and analytical nature.  Due to the method, the following sources have been used: Convention law, domestic legislation, case law, legal textbooks, journal articles, P&I Club Rules, preparatory works, and websites of international organizations and law firms. P&I CLUB covers many accidents which are not covered by any marine insurance. In pollution accidents, P&I covers every detail of the impact of pollution. The difference between P&I Club with marine loss insurance, in general, is that P&I Club covers the loss/damage more extensively, which is not covered by any marine insurance.

Concrete with Coconut Fibre Treated with Sodium Hypochlorite – Compressive and Flexural Strength
Authors: Ibrahim Norisham
Published: May 2023

Concrete needs to be reinforced to improve its engineering qualities. Coconut fibres were employed for this study since they are widely accessible and come in big numbers. The study compares the qualities of plain concrete and concrete reinforced with coconut fibre based on a laboratory experiment. Better management of these waste fibres will result from using coconut fibres. Two types of coconut fibre treatment were employed – treatment with tap water and treatment with sodium hypochlorite. It is found in this study that adding 1% of coconut fibre does not increase the concrete strength after 7 and 14 days of curing. However, it was discovered that using 1% coconut fibres treated using tap water increased the compressive and flexural strength of the concrete after 28 days of curing by roughly 4% and 3%, respectively. Compressive and flexural strength development agrees very well with each other. Hence, it is concluded that 1% was the ideal fibre concentration (by weight of cement) to obtain a better 28th day of compressive and flexural strength, although not for 7 and 14 days. However, concrete with the highest strengths demonstrated a very low slump value, only 20 mm. A smaller or bigger slump value showed smaller concrete strengths.
Effects of Pre-Treated Crumb Rubber as Sand Partial Replacement on Compressive Strength of Engineered Cementitious Composites (ECC)
Authors: Abdul Aziz Atiqah
Published: May 2023

This study was conducted to determine the surface morphology of crumb rubber (CR) treated with 10% Sodium Hydroxide (NaOH) solution at different periods and the compressive strength of the treated rubberised engineered cementitious composites (R-ECC). R-ECC is a type of engineered cementitious Composite (ECC) with CR as partial sand replacement. In contrast to the quasi-brittle nature of conventional concrete, engineered cementitious Composite (ECC) is distinguished for its tensile strain-hardening behaviour and tensile ductility. However, adding crumb rubber (CR) in ECC as partial sand replacement reduces the composites’ compressive strength owing to its smooth surface. The Scanning Electron Microscopy (SEM) test was conducted on the CR samples, which had been treated with 10% NaOH for 1, 2 and 3 days. Meanwhile, the compressive strength test was conducted on 45 cubes consisting of standard ECC, untreated R-ECC and treated R-ECC. The results discovered that 2 and 3 days of 10% NaOH treatment on CR enhanced its surface roughness, and 2 days NaOH treated R-ECC is the optimum duration for the highest compressive strength reduction. Therefore, the enhanced surface roughness of the CR used as partial sand replacement in the ECC can lessen the compressive strength reduction owing to better bonding between CR and cement matrix in the composites.
When a large refractive error is found in children, should we immediately order electroretinography?
Authors: Zabochnicki Mateusz , Pojda-Wilczek Dorota
Published: May 2023

Electroretinography is a useful tool used in diagnosing retinal disorders. Refractive errors are a common and increasing group of abnormalities, which, if undiagnosed, may lead to complications. Physiologically, i.e., refraction of the child’s eye, evolves from myopic or hyperopic after birth, towards emmetropic. However, high refractive errors tend to present with retinal diseases. Early electroretinography is a great diagnostic test that allows its detection. Because of that, it can help avoid loss of eyesight and prevent future implications. Unfortunately, low accessibility and interpretational difficulties are main barriers in wider implementation of that method.

Durante el siglo XIX se va a producir un profundo cambio en las formas de organización económica determinado por la Revolución Industrial, asistiéndose al paso de una economía de base agrícola y comercial a una economía de base industrial y a la consolidación de un régimen de mercado libre, regido por la oferta y la demanda, frente al sistema gremial y corporativista que había predominado durante los siglos anteriores.

Background

Three dimensional (3D) facial imaging is becoming a popular method of facial analysis and a means of anthropometry. There is potential for 3D imaging to provide enough diagnostic information to parallel lateral cephalograms, which could, in time, reduce the need for radiation exposure to patients. The present study aimed to assess the accuracy of the Bellus3D ARC-7 (Bellus) camera by comparing the measurements of soft tissue facial landmarks obtained from Bellus scans to the measurements taken using Vernier callipers.

Method

Nineteen anatomical points were located on four subjects using a standard black ballpoint pen on a white, circular sticker. Distances were measured between these points using digital callipers, with the subject in a resting pose. This was repeated twice by two examiners for each subject. Two examiners subsequently performed measurements of each subject in a smiling pose. Following landmark identification, images were captured under standard conditions, using the Bellus camera. The same measurements were obtained digitally, repeated twice by two examiners for each subject in both resting and smiling poses.

Results

There was high precision in repeated measurements on the digital models, with less than 1.5 mm deviation between measurements. Both intra-examiner and inter-examiner reproducibility were greater following the digital measurements compared to manual measurements, with 100% of the digital measurements of landmarks falling within a set threshold deviation of ≤1.5 mm. When comparing the manual and digital measurements, the greatest deviations (>1.0 mm) occurred in regions around the cheeks and lower third of the face, while the measurements for the ears and midline structures (forehead and nose bridge) deviated the least (≤1.0 mm). This was demonstrated in models at rest and smiling.

Conclusions

The Bellus system produced an accurate and true image of the face from which reproducible measurements can be made within and between examiners. 3D facial images from the Bellus3D ARC-7 system were comparable to direct anthropometry, therefore the use of 3D facial scanning in orthodontics for diagnosis and treatment planning appears promising.

Wood is a natural material and is subject to degradation due to weather, UV radiation, and humidity. Wood is composed of many components. The basic structural elements of wood include cellulose, hemicellulose, and lignin. Furthermore, these are accompanying substances, which also include extractive substances. Specifically, these substances, together with lignin, have a negative effect on its life thanks to their chemical reactions, which are initiated mainly by UV radiation (so-called photodegradation). This study evaluates the effect of controlled degradation of extractives and lignin on the surface of the wood before the application of the coating system and also on its overall service life. Samples of larch wood (Larix decidua Mill.) were exposed to exterior natural influences in Prague (Czech Republic) according to EN 927–3 (2020) for 10 and 20 weeks. Subsequently, the samples were sterilized in an autoclave, due to possible contamination of the surface with fungi. The specimens were then treated with two oil–coating systems (V–420 and V–429). Subsequently, they were exposed to artificial aging in a UV chamber according to EN 927–6 (2019). Testing occurred at predetermined time intervals of 0, 1, 3, and 6 weeks, roughly corresponding to 0, 2, 6, and 12 months outdoors. The evaluated factors were the change in color, gloss, and surface wettability. The results showed a slightly positive effect of surface washout lasting ten weeks before applying the coating system.

Scots pine (Pinus sylvestris L.) is the most widely distributed pine species in the world. In Germany, as in many other European countries, it is a very important species both culturally and economically. Few studies have focused on bark volumes being delivered to the wood industry together with the roundwood, being potentially a valuable resource for material or energetic utilization. Therefore, logs from six different forest sites were collected and bark variables including double bark thickness (DBT) in three different categories, diameter, and bark damage (as a degree of miss-DBT) in three different categories, diameter, and bark damage (as a degree of missing bark) were measured and analyzed in order to model bark volume (Vbark) and bark mass (Mbark). The correlation analysis using Pearson’s method showed that the highest correlation coefficients were observed from the correlation between DBT and Vbark, as well as between DBT and Mbark. Also, results demonstrated that with DBT greater than 20 mm, the percentage of Vbark exceeded 20%. Finally, different linear regression models were recommended to predict Vbark and Mbark based on the other variables. The results of this study can be used in different wood industries in order to predict bark volume and bark mass of e.g. truckloads or roundwood stacks.

As a result of climate change, the species structure of forest stands is gradually changing when the growing share of core species of deciduous trees at the expense of conifers places demands on its future efficient processing into final products. This study evaluates the influence of the surface modification of the heartwood of oak (Quercus robur) with five selected chemical modifiers on the strength of the glued joint with the used one-component PUR adhesive for interior and exterior structural applications. Samples of test bodies produced according to the standards were exposed to the given environment and subsequently subjected to a test using the method of determining the longitudinal shear strength under tensile stress. By applying a chemical modification to the surface layers of the glued surfaces of oak wood, the tannins in the surface layers were neutralized, increasing the adhesion of the glued surface. The resulting values of the strength of the glued joints with the applied chemical modification of the heartwood surface also confirmed this.
Корпоративная идентичность и отношение к лицею учащихся базовой школы РАН: на пути к бренду в общем образовании исследовательской специфики
Authors: Махова Ирина Юрьевна
Published: May 2023

В статье рассматривается формирование корпоративной идентичности учащихся как воспитательный ресурс развития ценностно-смысловой сферы и профессиональных предпочтений выпускников, связанных с исследовательской деятельностью. Показано, что корпоративная идентичность в образовании обладает объяснительным и прогностическим потенциалом в отношении принятия ценностей организации ее членами и обеспечивает смысловую переработку запретов и ограничений. Предпринятое эмпирическое исследование с помощью проективной модифицированной методики С. Деллингер выявило особенности представлений совокупного субъекта (учащихся 8–11-х классов) о лицее как учреждении, ориентированном на познание, но не обладающем креативностью. Обнаружено снижение корпоративной идентичности с возрастом, имплицитное восприятие значительной частью учеников лицея, отличающегося от других школ, формирующего познавательную активность, но не устойчивого, лишенного, по мнению учащихся, свободы для выражения индивидуального мнения, инакомыслия. При этом отношение к лицею как к образовательному бренду действительно определяет корпоративную идентичность, приверженность лицею, его нормам, правилам, способствует чувству гордости за достижения участников образовательного процесса. Ключевые слова: корпоративная идентичность, проектно-исследовательская деятельность, бренд в образовании, эмоционально-ценностное отношение.

In this paper the different salient features of the old and new version of Indian paper currency notes have been studied and compared. The list of security features of Indian currencies have been mentioned and discussed. Various kinds of conventional methods that are used to detect authenticity and to recognize a note has been explained. It has been observed that each technique has its own objective and significance. There are many conventional tools that can be used to recognize different features of a note. To classify different techniques, the detection method comprises of two parts i.e., the first line detection method and the second line detection method. Physical dimensions of a paper note along with its thickness have pointed out a new parameter which is the diagonal of a genuine currency note that has been calculated to obtain a proposed standardization and each value differs from different denominations. The classification of different Indian banknotes giving emphasis on its characteristics, both salient and security features, dimensions and detection methods has been mentioned and briefly explained. For validation of the paper currencies two methods have been discussed emphasizing on fuzzy logic framework by taking into consideration a 3-point likert scale and another validation methodology using digital image processing
