Abstract: This research aims to find out how important the role of parents is in elementary school students' anxiety regarding learning mathematics. The research method we use is a qualitative research method with a case study approach. Researchers used interview instruments, questionnaires, questionnaires and documentation in the data collection process. The research results showed that of the 31 respondents, all had anxiety related to learning mathematics, although at different levels, namely mild, moderate and severe. Most of them feel anxious when working on questions and approaching mathematics exams. The role of parents in dealing with children's anxiety is still not optimal. In overcoming anxiety in children, parents only tend to provide assistance, motivation and enthusiasm to continue learning. So, parents still don't understand how to provide strategies for dealing with anxiety that occurs in children.

The “Black Swan Principle” and the Genetics of Complex Diseases
Authors: Novelli Giuseppe , Reichardt Juergen K V
Published: March 2024

The black swan principle is a philosophy theory created by Nassim Nicholas Taleb that seeks to explain rare and unpredictable events, appearances that seem to defy logic or rational explanation. These events, termed "Black Swans," have been observed in various domains, including finance, public administration, infectious diseases, and ecology. The concept of Black Swans has gained recently, significant attention in academia and practice due to its relevance in understanding extreme and rare occurrences. The “black swan” concept has been used in genetics for the unexpected developments that genome sequencing would reveal and which could have consequences for healthcare systems (e.g., increase in often unnecessary and inappropriate diagnostic investigations, increase in non-patients, etc.).
Fra teknologianvendelse til teknologiforståelse via Lærerens Grundfaglighed

Published: March 2024

Denne artikel præsenterer fund fra en undersøgelse af kompetenceudvikling i teknologiforståelse for undervisere i læreruddannelsens pædagogiske fag. Artiklen analyserer tre cases, der viser, hvordan undervisernes konkrete erfaringer med teknologianvendelse kan frustrere og skabe barrierer, men også kan begejstre og give muligheder for koblinger til egen eksisterende faglighed. Artiklen viser, hvordan koblinger til egen faglighed kan udgøre løftestang for udviklingen af undervisernes begyndende teknologiforståelsesfaglighed, hvor de styrket af egen faglighed bliver i stand til at diskutere og agere teknologiforståelsesfagligt. Artiklen foreslår en model til at begribe, hvordan denne faglige og erkendelsesmæssige vekselvirkning med afsæt i teknologianvendelse giver forudsætninger for at udvikle teknologiforståelsesfaglighed hos underviserne. Dermed giver artiklen et indblik i, hvordan arbejdet med teknologiforståelsesfaglighed, kan bygge produktivt på teknologianvendelse og underviseres eksisterende faglighed.
Miskendt sorg hos partnere til personer med en erhvervet hjerneskade
Authors: Schmidt Thøgersen Cecilie Marie , Glintborg Charlotte
Published: March 2024

Krise- og sorgreaktioner hos partnere til per- soner, der rammes af livsforandrende sygdom kan ses som naturlige reaktioner. Til trods for et stort fokus på sorg i samfundsdebatten er forskning i sorg og sorgforståelser i forbindelse med livforandrende sygdom begrænset (Calvete & López de Arroyabe, 2012). Derfor under- søger dette studie sorgoplevelser hos partnere til personer med en erhvervet hjerneskade og udforsker, hvordan den enkeltes sorgoplevelse påvirkes af aktuelle kulturelle og sociale dis- kurser.Undersøgelsen tager udgangspunkt i fire semistrukturerede interviews med partnere til personer med erhvervet hjerneskade, 2-5 år efter hjerneskaden indtraf. Deltagerne er to kvinder og to mænd, i alderen 50-66 år.Gennem en diskurspsykologisk analyse un- dersøges de fire deltageres oplevelse af sorg og hvordan denne influeres af egne forståelser af begrebet sorg, samt kulturelle og samfundsmæssige diskurser (Davies & Harre, 1990).Resultaterne viser store forskelle i sorgoplevelsen mellem de enkelte informanter. Ligeledes kommer analysen ind på, hvordan sorgen kan opleves som miskendt. Analysens resul- tater diskuteres op mod samtidens sorgforståelser, hvor sorg på den ene side kan ses sommiskendt og hvor sorg på den anden side er blevet en diagnose. (Prolonged Grief Disorder) På baggrund af studiet anbefales fremadret- tet et øget fokus på anerkendelsen af forskelligartede tab i forbindelse med det at blive pårørende, samt en øget accept og normalisering af sorgens forskelligartede udtryksformer.

Published: March 2024

Wooden boats are commonly considered to be more cost effective compared to fiberglass boats, and no study has described the economic disparities between the two vessel types. Therefore, this study aimed to provide a comprehensive economic comparison between wooden and fiberglass boats, including the return-on-investment timelines and the potential profitability. A qualitative method was used in this study, and the data were collected through survey techniques. The economic analysis results showed that the average Net Present Values of wooden and fiberglass boats were IDR 72,935,055 and IDR 84,511,500 respectively. The average Net Benefit-Cost Ratio and the average Internal Rate of Return for both vessel types were 1 and 11%. The average Payback Period was approximately 6.6 years for wooden boats with a profit of IDR 8,902,000, and 6 years for fiberglass boats with a profit of IDR 11,936,944. In conclusion, the use of both vessels was not only acceptable but feasible for operation.
Datos sobre el estatus de la ardilla roja Sciurus vulgaris Linnaeus, 1758 en la Sierra de Gata (Salamanca)
Authors: García Pablo , Mateos Isabel
Published: March 2024

The red squirrel Sciurus vulgaris is a widely distributed species in the Iberian peninsula but in the western Sistema Central is scarce and ocurrs in isolated nucleus. During spring, summer and autumn 2008 sistematic transects for obtaining data about the status of the species in the north of the Sierra de Gata were carried out. The poor results (7.41 % of samples positives) indicates the species is rare in the area, detected in two pine forest of Pinus pinaster in the proximities of the villages of Navasfrías (29TPE86) and Robleda (29TQE07). The estimated densities from drey counts were 0.42 squirrels/ha and 1.06 squirrels/ha, respectively, comprised in the range of variation dated for this species. The scarcity of the species can be related to a highly punctual presence, to a recent expansion from the closest population nucleus (Sierra de Francia) or as a consequence of an human-induced introduction.

Background

The present study investigated the population structure and breeding biology of the burrowing brachyuran crab species Dotilla blanfordi Alcock, 1900, which is commonly found on the sandy beach of Bhavnagar, located on the Gulf of Kachchh, Gujarat coast, India.

Methods

Monthly sampling was conducted from February 2021 to January 2022 at the time of low tide using three line transects perpendicular to the water line, intercepted by a quadrate (0.25 m2) each at three different levels of the middle intertidal region: 20 m, 70 m, and 120 m. The quadrate area was excavated up to 30 cm and sieved for specimen collection. The collected specimens were categorised into different sexes viz., male, non-ovigerous female, or ovigerous female. For the fecundity study of D. blanfordi, the carapace width (mm) as a measure of size as well as their wet weight (g), size, number, and mass of their eggs were also recorded.

Results

The study revealed sexual dimorphism among the population, with females having significantly smaller sizes as compared to males. The overall population was skewed towards females, with a bimodal distribution of males and females. The occurrence of ovigerous females throughout the year suggests that the population breeds incessantly throughout the year, with the highest occurrence in August and September. A positive correlation was observed between the morphology of crabs (carapace width and wet body weight) and the size, number, and mass of eggs.

Published: March 2024

The study investigated the effects of giloy (Tinospora cordifolia) and ascorbic acid supplementation along with different bedding materials (sand B1, saw dust B2 and wheat straw B3) on egg shell quality of Japanese quails. A total of 432 chicks (7 day-old) of Japanese quails were divided into three equal groups (144 each) for different bedding material used and each group was further subdivided into four groups (each of 36 chicks) on the basis of dietary treatment (control T0, giloy T1, ascorbic acid T2 and combination of both T3). The current study was carried out at the Poultry unit, Livestock Farm Complex, College of Veterinary and Animal Science, Bikaner, for 24 weeks, from October 2020 to April 2021. As a result, the birds were evenly and randomly allocated into 12 treatment groups total, with 36 birds in each group. Each group was then further split into two replicates, each with 18 birds. The quails were given three different diets: a basal diet (control, T0), one supplemented with giloy 5 g/kg, another with ascorbic acid 240 mg/kg, and a combination of both in dietary treatment groups T1, T2, and T3, respectively. There was a highly significant (p<0.01) impact of adding nutrients and using different bedding materials on the Japanese quail's egg shell thickness and weight. Egg shell weight and thickness were greater in the sawdust bedding material group in the current experiment. It was discovered that there was no significant interaction on these features between nutritional supplements and various bedding materials.

Published: March 2024

The present study reports experimental data on substrate specificity and some properties of the extracellular enzyme with oxidase activity isolated from the mycelium of the higher fungus Neonothopanus nambi IBSO 2391 by treating the biomass with \(\beta\) -glucosidase. Gel-filtration chromatography showed that molecular weight of the isolated enzyme was 80 kDa. Spectral analysis did not reveal any chromophore components in the enzyme. The extracellular oxidase of the basidiomycete N. nambi IBSO 2391 was active with most of the aromatic compounds chosen as model substrates. An important fact is that the enzyme exhibited catalytic activity with no hydrogen peroxide or any other mediators added to the reaction mixture. The highest activity of the enzyme was observed in reactions with veratryl alcohol and hydroquinone. In reactions with guaiacol and aromatic amines (diaminobenzidine, o-dianisidine), the level of activity of the extracellular oxidase was considerably lower – by a factor of 2.5–3.5. In reactions with resorcinol, phenol, and caffeic acid, the catalytic efficiency of the enzyme was no greater than 6% of its activity with veratryl alcohol. Kinetic parameters of enzymatic reactions were determined for the most efficiently oxidized substrates. The addition of the chelating agent of divalent metal ions (EDTA) did not affect the activity of the extracellular oxidase from the fungus N. nambi IBSO 2391, indicating the absence of divalent metal ions in the molecule of the enzyme. At the same time, addition of the SH reagent (DTT) increased catalytic efficiency of the enzyme. The study showed that the extracellular oxidase of the fungus N. nambi IBSO 2391 functions in wide ranges of temperature and pH of the reaction medium, showing the highest catalytic activity at temperatures between 22 and 35 °C and pH 6.0. Results obtained in the current study provide the basis for studying potential uses of the isolated enzyme in biomedical analytics and bioremediation.

Published: March 2024

Alkyd resin prepared from Gossypium hirsutum (cotton seed) seed oil and immersed in silver nanoparticles has been characterized and evaluated using standard analytical methods. Gas Chromatography-Mass Spectrometry (GCMS) was used to determine the fatty acid profile of the seed oil extract which was physicochemically characterized using AOAC standard method. The results obtained are as follows: Iodine value; 102.36g I2/100g, Acid value; 3.19 mgKOH/g, Saponification value; 202.32 mg/KOH/g, Refractive index; 1.46, Specific gravity; 0.91 and Moisture content; 1.20. The alkyd resin was prepared using alcoholysis-polyesterification reaction. The prepared resin was then immersed in silver benzoate to give Gossypium hirsutum immersed silver nanoparticle alkyd resin (GHSOR-AgNps) and the formulated resin was analyzed using Ultraviolet-Visible spectroscopy (UV), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). UV-visible spectroscopy was used to analyze the silver benzoate salt. The performance of the formulated resin was assessed and revealed thus: soluble in both polar and non-polar organic solvents used in the study, dried through after 24 hours, showed chemical resistance to 0.1M NaOH with total removal, and its acid value was below 10 mgKOH/g. Therefore, Gossypium hirsutum seed oil (GHSO) has been shown to be a cost-effective, renewable and sustainable feedstock for alkyd resin production in the coating industry.
Influence of Organics, Boron and Silicon Nutrition on the Growth, Yield and Nutrient Uptake by Groundnut in Coastal Saline Soil
Authors: Kamaleshwaran R. , Elayaraja D.
Published: March 2024

The most common cause of coastal salt-affected soils is boron deficiency. In certain places, there are also deficiencies in zinc, iron, manganese, and copper. In numerous enzymatic processes related to groundnut growth, production, and quality, boron is crucial. It is now known that the main cause of the low groundnut production in coastal locations is a nutritional shortage. A helpful or quasi-element that can reduce salinity stress, improve boron availability, and increase the amount of available beneficial cations is silicon. Therefore, it becomes essential to include silicon as a beneficial nutrient and boron as a micronutrient in the fertilization program in order to increase groundnut output in salinized conditions. Further, the poor nutrient retention and leaching of applied nutrients necessitates the application of increased rate of nutrients and bulky organic manures. The field experiment was carried out in a farmer’s field during December - March, 2022 at Singarakuppam coastal village, near Chidambaram in Cuddalore district of Tamil Nadu. The experimental soil was sandy in texture and taxonomically classified as Typic Ustipsamments with pH – 8.25, EC– 4.11 dSm-1 and represented low status of organic carbon (2.36 g kg-1). Regarding available nutrient status, it was low in alkaline KMnO4-N (139.91 kg ha-1), low in Olsen-P (9.48 kg ha-1) and medium in NH4OAc-K (165.67 kg ha-1).The available B and Si content were 0.24 and 32.46 mg kg-1, respectively. The results of the study clearly indicated that the treatment (T12), which received combined application of borohumate at 1.5 kg B ha-1 + diatomaceous earth at 60 kg Si ha-1 through soil application along with foliar application of borohumate at 0.5% + silixol plus at 1.0% twice at pre - flowering stage (PFS) and at flowering stage (FS) + recommended dose of NPK and composted coirpith (CCP)at 12.5 t ha-1 recorded the highest growth, yield, quality and nutrient uptake by groundnut.

Results: The extracts had variable percentage yield with methanol root extract having the highest (3.80%). The results of the phytochemical screening showed the presence and absence of some phytochemicals while the proximate composition varied significantly (P=0.002). The                  moisture content was in the range of (6.75 to 9.50%), protein (8.99 to 11.56%), crude fiber (2.00 to 7.33%), fat content (47.33 to 51.06%), ash content (15.80 to 17.60%) and carbohydrate (8.33 to 13.84%) in the methanol extracts of the root and stem. Gas Chromatography-  Mass Spectrometry, (GC-MS) determined some specific phytocompounds in the extracts, GC-MS analysis furnished a combined total of 14 phytocompounds in the two extracts with unsaturated aliphatic hydrocarbons and fatty acids being the major families detected.
Conclusion: The extracts upon analysis revealed high potential for a vast number of bioactive compounds which justifies its use for various ailments by traditional practitioners. Phytochemical components identified in this study advocate the presence of ethnomedical and phytopharmaceutical versality of each of the extracts which could be used in the therapeutic drug formulation studies.

Genetic variability, heritability, and genetic advance as a percent of mean were evaluated for 17 characters in chillithrough field assessment. The study encompassed all observed traits and analysis of variance revealed significant variability among genotypes for each character. Notably, Number of fruits per plant, Average fresh fruit weight (g), Green chilli yield per plant (g), Dry chilli yield per plant (g), Dry chilli yield per plot (kg), and Dry chilli yield per/ha (q) exhibited higher values for both Genotypic Coefficient of Variation (GCV) and Phenotypic Coefficient of Variation (PCV), indicating substantial genetic variability with minimal environmental influence.Plant height (cm), Average fresh fruit weight (g), Number of fruits per plant, Fruit diameter (mm), Number of seeds/fruit, Green chilli yield per plant (g), Dry chilli yield per plant (g), Dry chilli yield per plot (kg), and Dry chilli yield per/ha (q) demonstrated high heritability and genetic advance as a percent of mean. This suggests the prevalence of additive gene action in the inheritance of these yield attributes. Consequently, simple selection is anticipated to be effective for enhancing these traits.

Authors: Abinaya  , Kumar A  , Sinha R  , Singh A
Published: March 2024

Hypoplastic acute leukemia (HAL), also known as smoldering leukemia, is a form of atypical leukemia. It is a rare entity and currently defined as having cellularity of < 20% in bone marrow with >20% blasts at presentation. Hypocellular acute myeloid leukemia are more frequent than hypocellular variant of acute lymphoid leukemia. Although cases of hypoplastic acute myeloid in children and younger age group have been reported in literature, they are extremely rare. These cases pose a diagnostic challenge to the hematopathologist and treating physician, as hematological features of hypoplastic acute myeloid leuckemia (AML), hypocellular myelodysplastic syndrome and aplastic anemia are similar. Therefore, it is crucial to distinguish between these diseases as treatment modalities are different for each entity. Very few reported cases are available in literature. Hereby, we report this case of hypocellular AML-M0 in a 16-years-old Indian boy.

Frontline demonstrations were conducted with recommended scientific package and practices at farmer’s fields in the Chhattisgarh plain agro-climatic zone of Balaghat district, Madhya Pradesh to evaluate the performance of two rice varieties viz., JR-81 and JRB-1under irrigated conditions during Kharif 2019. The data on yield and economics of demonstrated under FLD, when compared with farmer’s practices on popular rice variety MTU-1010 revealed that both the rice varieties performed superior to MTU-1010.  JR-81 and JRB-1with improved production technologies showed increased mean grain yield by 17.17% over existing farmers practice with Rs. 2450 ha-1 extra expenditure on inputs. The mean extension gap (7.80 q ha-1) and mean IBCR (4.78) recorded were sufficiently high, which may motivate the farmers to adopt JR-81 and JRB-1 varieties with the improved rice production technology.

Published: March 2024

Citrus fruits are well known for their taste, flavour, aroma and fragrance, with rich vitamin C content. Fruits are rich in various nutrients, minerals and vitamins because of which they have the important role in pharmaceutical and nutraceutical industries. The citrus fruit cultivation experiences many challenges through biotic and abiotic stresses leading to occurrence of pest and diseases coupled with physiological disorders. The occurrence of pre and post-harvest disorders due to abiotic stresses and improper harvesting methods and unhygienic field conditions would lead to reduction in yield, fruit quality and commercial value of the produce and products. Improper harvesting and management in citrus fruits reduce the quality and appearance of the fruits. Pre-harvest disorders like granulation, fruit cracking, puffiness, superficial rind pitting, creasing and sunburn, and post-harvest disorders such as chilling injury, oleocellosis, rind staining, peteca, stylar end breakdown and stem end rind breakdown are the resultant disorders repeatedly noticed in citrus fruits. Maintenance of garden hygiene, flower regulation, water and nutrient management, bahar treatment, use of growth regulators and crop load coupled with canopy management would help in minimising the above disorders in citrus fruit crops.
Architecture + Textiles = Architextiles
Authors: Garcia Mark
Published: December 2006

A hybrid term, ‘architextiles’ encompasses a wide range of projects and ways of thinking that unite architecture and textiles. By way of introduction to this issue, guest‐editor Mark Garcia highlights the significant rise of interest in this confluence by theorists, architects, engineers, textile designers, materials scientists and artists. He also explains how, as a hybrid mode of design and practice, architextiles is better able to respond to society's fast‐changing cultural and consumer demands, enabling the production of more dynamic, flexible, interactive, event and process‐based spaces.

Textiles in Architecture
Authors: Quinn Bradley
Published: December 2006

‘The cutting edge in architecture is not sharp, but sensuous and soft.’ As textiles begin to emerge as megamaterials, Bradley Quinn explains how architects are pioneering new possibilities for soft structures. Fabric‐formed environments are fashioning tensile buildings and inflatable pavilions, while the tailoring techniques of braiding, weaving and pleating are building supple skyscrapers and bioclimatic enclosures.

‘Otherworldliness’: The Pull of Black Velvet, Latex, Tights, Quilts, Tablecloths, and Frocks: An Interview with Will Alsop
Authors: Garcia Mark
Published: December 2006

Will Alsop is most immediately identified with the expressive, colourful and painterly in architecture. His reputation as architecture's masterly Abstract Expressionist all too easily overshadows his engagement with more specific material and conceptual concerns. In conversation with Alsop at his Battersea studios, Mark Garcia discovered that a preoccupation with textiles has been latent in his work since his studies at the Architectural Association (AA) in the early 1970s. It is only, however, in a recent body of work that Alsop has started to innovatively bring it to the fore by translating the unexploited qualities of textiles into a plausible architecture.

Skin/Weave/Pattern
Authors: Coates Nigel
Published: December 2006

‘Fabric is the perfect mediator between the firm and the flowing.’ Nigel Coates celebrates the textile's rediscovery as a metaphor for the architectural envelope, liberating it from its reputation as having only a supporting, ‘comfort role’ in the interior. He describes his own experiments with textiles at Branson Coates Architecture and the Royal College of Art (RCA), in which they alternately become skin, weave and pattern operating at every scale from the individual body to the urban plan.
