Feasibility and Acceptability of Using FirstPlay® to Enhance Mother–Child Interaction: A pilot study of mothers’ perspectives
Authors: Siu Angela
Published: June 2023

Background

Although there is evidence that human touch facilitates mother–child bonding, mothers’ understanding of how to connect with and develop the emotional regulation of their babies remains unclear.

Objectives

This study used a Storytelling Massage program to investigate mothers’ experience of practicing reciprocal interactions with their children. Specifically, it explored the efficacy of multi-sensory activities for building healthy parent–child bonds.

Method

Participants included 12 mothers with children between 8 and 23 months. These mothers participated in a 6-session program on FirstPlay Infant Storytelling-Massage Intervention (FirstPlay Therapy) and attended an individual semi-structured interview after the program. Data were analyzed using a phenomenological approach.

Results

The FirstPlay program positively affected the participants’ self-efficacy in parent–child bonding and parenting beliefs. Five themes were identified: “bonding with the child—connect and engage,” “attending to the child’s uniqueness and needs,” “developing a structure and a daily routine,” “feeling calm and relaxed as a person,” and “gaining confidence as a mom.”

Conclusion

The results of this study further support the need for low-cost, high-impact programs that enhance parent–child interactions. Limitations of this study are discussed. Future research and practical implications are also suggested.

Published: June 2023

The article concerns the problem of lateral stabilization of a tricycle with variable front wheel track. The vehicle can operate in two modes: with the front wheels folded out and connected. A bicycle designed for people with special needs. The element that requires elaboration is the stabilization while driving with the front wheels unfolded. In this mode, a metastable state is created. When the lateral angle of the slope exceeds the limit value, the lateral force causes the lateral tilt. This phenomenon should be treated as a disadvantage as it makes it difficult to smoothly tilt the bicycle, which can lead to disorientation of the rider and difficulty in maintaining balance. The article presents mathematical simulations that allow for the analysis of factors influencing the discussed phenomenon.

The use of Voice over Internet Protocol (VoIP) innovation is rising due to its various merits. Nevertheless, the ineffective use of bandwidth is a key dilemma that restricts the fast-rising use of VoIP innovation. The main factor behind this ineffective use of the bandwidth is the sizable VoIP packet preamble. This research creates a technique to address this dilemma of packet preamble. The created technique is known as payload elimination (PldE). The fundamental concept of the PldE technique is to exploit the information (elements) of the VoIP packet preamble that is superfluous for point-to-point calls. In general, these elements are utilized to transport the payload of VoIP packets. Consequently, the payload size of VoIP packet will be lowered or removed, preserving the available bandwidth. The performance test of the PldE technique indicated an improvement of up to 41.6% in the exploitation of IP network bandwidth. So, the PldE technique is showing signs that it could help solve the problem of the IP network's inefficient use of bandwidth.
Improving of Interaction of Routes at High Density Stops by Adjusting Bus Arrival Time
Authors: Dashdamirov Fuad
Published: June 2023

A significant part of the movement of the population in large cities is carried out by bus transport. Higher accessibility and connection to the network of other types of public transport are the main features of bus transport. The need for mass passenger transportation in Baku mainly is met by the metro and bus transport. A small number of metro stations and insufficient coverage of the city territory by metro network have significantly increased the load on the bus service. With the increase in passenger traffic, the frequency of bus routes has increased, and the intervals have decreased. As a result, bus traffic on some streets has become more intense. This led to an increase in the number of buses arriving at the stops at the same time and the formation of queues in front of the stops. To solve the problem, the article proposes a method for coordinating bus schedules of different routes and adjusting the time of arrival at a stop without changing the intervals. As a result of applying the proposed methodology, by modelling the sequence of bus arrivals in the Anylogic program, a reduction in queues and loss of time in front of the bus stop is justified. Simulation testing was carried out for the scenario of bus movement both in the general flow and along the bus lane.

Published: June 2023

The aim of this paper is to optimize turbine blade cooling channels by applying jet impingement Method. The selection of experiment data for NASA 3CX turbine blade, and 3D model using solidworks software and create computational fluid dynamics (CFD) simulations used to model the coolant flow and temperature distribution in the vane, while experimental testing can validate the CFD results and provide additional insights into the cooling system's performance., ANSYS FLUENT code was used as a CFD solver, and ANSYS ICEM-CFD was used for mesh generation. MATLAB code is used for calculation using experiment data and this was helpful for simulations. Heat transfer conjugation analysis bases SST shear stress analyses K-ω turbulent model. The results conclude that providing additional information about the cooling channels and how they differ in the studies being compared. The results demonstrate that the cooling channels' hydraulic diameter decreases by a significant percentage (up to 49.70%–69.55%) as they are drawn to the trailing edge of the blade. This can have a significant impact on the heat transfer coefficients and the performance of the cooling system. The pressure side of the turbine blade is observed to follow the Hylton Model, while the current study predicts a large over-anticipated heat transfer coefficient around the Turbine blade head and on the bulk of the suction side. In terms of average heat transfer coefficient, the two models differ by 23.36%. The authors found that the cooling effectiveness for the Optimized jet impingement model is 0.4892 for whole blade and compared it with the cooling effectiveness for the optimized jet impingement model, which is 0.6936, The results of the comparison between the base model and the optimized jet impingement model suggest that the optimized model has a significantly higher cooling effectiveness. The increase in cooling effectiveness of 29.46% for the whole blade and 28.823% for the trailing edge indicates that the optimized jet impingement design provides improved cooling performance. These results highlight the importance of considering optimized cooling designs for turbine blades to maintain efficient and safe operation.

Published: June 2023

The verbal and non-verbal aggressiveness of adolescents has been increasing. It is a form of aggression that involves hostile and coercive actions towards others that may result in emotional or physical harm. This study aims to examine the Islamic parenting style of mothers, the primary caregivers in Javanese culture in Indonesia, as well as the social interactions with peers in relation to aggressive behavior. The participants of this study were 410 high school students aged between 15 and 19 years old (M = 16.52, SD = 0.793), consisting of 210 male students and 200 female students. Participants were selected from eight schools in Sleman City (4 senior high schools and four vocational high schools). The data was collected using the aggression scale, maternal parenting style, and social interactions with peers. Data were analyzed using Partial Least Square-Structural Equation Modeling (PLS-SEM) with Smart-PLS 4. The study results show a good fit model, indicating that aggression is influenced by Islamic maternal parenting style with social interactions with peers as a mediator. Social interactions have a mediating effect on the relationship between Islamic maternal parenting style and adolescent aggression. Another finding reveals that each Islamic maternal parenting style negatively affects aggression. Adolescent aggression can be controlled through Islamic maternal parenting style (i.e., authoritarian, authoritative, and permissive) and peer social interaction as a mediator.
Radiological anatomy and injuries of the condylar strap and Kaplan fibers associated with ACL pathology
Authors: Chandra Aakanksha Agarwal , Chandra Abhishek , Murray Timothy , Azam Md. Quamar
Published: June 2023

Objectives:

The study aimed to identify the Kaplan fiber (KF) complex, focusing on the condylar strap (CS) which are fiber straps on the lateral aspect of the knee related to the iliotibital complex, on magnetic resonance imaging (MRI) of knees performed for acute anterior cruciate ligament (ACL) injury, measure the distances of insertion from the lateral joint line, and identify injuries to these structures.

Material and Methods:

Retrospective analysis of 134 MRIs of knees with acute ACL tear was performed. The proximal and distal KFs and the CS were identified on at least one plane on MRI. The distance of their femoral attachment from the lateral joint line and injury to these structures with concomitant knee injuries was documented. Data analysis was performed using the SPSS software.

Results:

KFs were identified in 97.2% and CS in 72% of the MRI knees. The mean distance of the proximal KF from the lateral joint line was 59.1 mm, while that of the distal KF was 42.4 mm. The CS attached 35.6 mm proximal to the lateral joint line. KF complex injury was present in 34% of cases with ACL tear. The MRI finding of meniscal tear and bone marrow edema in a classic pivot shift impaction injury pattern had a significant positive correlation with KF injury.

Conclusion:

This radiological study confirms the existence of CS on MRI. There is a positive association of KF injury with meniscal tears and bone marrow edema in patients with acute ACL tears. Future biomechanical studies focusing on CS are needed to identify its contribution to anterolateral stability.
Intraluminal arterial transit artifact as a predictor of intracranial large artery stenosis on 3D time of flight MR angiography: Expanding the application of arterial spin labeling MRI in ischemic stroke
Authors: Peer Sameer , Singh Paramdeep
Published: June 2023

Objectives:

The objective of this study was to evaluate the diagnostic value of “intraluminal arterial transit artifact” in the prediction of intracranial large artery stenosis and to determine if this finding is predictive of ischemic stroke in the territory of the involved artery.

Material and Methods:

The presence of arterial transit artifact (ATA) within the lumen of an intracranial large vessel was noted on three-dimensional time of flight (3D-TOF) magnetic resonance angiography (MRA) (ATA group). The patients with stenosis but with no ATA (no-ATA group), patients with total occlusion (total occlusion group), and patients with no stenosis/occlusion (normal group) were included in the analysis.

Results:

There were four groups of patients included in the final analysis, the ATA group (n = 22), the no-ATA group (n = 23), the normal group (n = 25), and the total occlusion group (n = 9). Among patients with any demonstrable stenosis (n = 45), the presence of ATA within the stenotic segment was predictive of stenosis of ≥56% (Sensitivity of 100% [85.2–100, 95% CI], specificity of 100% [86.4–100, 95% CI]), with area under curve of 1.0 (0.92–.0, 95% CI). The presence of intra-arterial ATA signal was significantly associated with ischemic stroke as compared with the no-ATA group (86.36% vs. 26.08%, P = 0.0003). Intraluminal ATA was found to be an independent predictor of infarction in the territory of the involved artery.

Conclusion:

Intraluminal ATA is predictive of stenosis of at least 56% in the involved artery on 3D-TOF MRA. Intraluminal ATA sign may be an independent predictor of infarction in the territory of the involved artery.
Dermoid cyst simulating mucocele of lacrimal sac: A case report
Authors: Varte Daniel Varrosang , Altaf Abu
Published: June 2023

A dermoid cyst in the orbit is a choristoma (clump of normal tissue in an atypical location). It results from the migration of ectoderm to a hypodermic location along embryonic lines of closure. Orbital dermoid cysts are usually located superiorly, either temporal or nasal. A dermoid cyst situated close to the lacrimal sac area is extremely rare (Only six published cases to the best of our knowledge). Here, we report a case of a dermoid cyst presenting with swelling over the lacrimal sac area simulating mucocele. The mass was excised by an external dacryocystorhinostomy (DCR) incision approach and the histopathological examination revealed a dermoid cyst. Although rare, the dermoid cyst should also be considered as one of the differential diagnosis in case of swelling in the lacrimal sac area.

Authors: Gadde Samata , Poda Sudhakar , Gundlapally Jyothsna
Published: June 2023

COVID 19 hit the year 2019 and created havoc in the society. It has shown an extensive resistance by evolution resulting in several variants. One such variant Omicron was identified in late December 2021. Studies revealed that these variants are part of the natural phenomenon of the virus’s mutational evolution. These mutations caused genetic variation which can be considered as one of the reasons for failed efficacy of previous vaccines, thus, making it a vital concept of studying the genetics of these viral strains and their inter strain variations. The first objective of the current study is to identify the sequence variations among the initial SARS corona virus identified and the omicron variant targeting the Spike Glycoprotein A. These spike proteins are known to be the major reason for the viral evolution and strain variation. The regions of variation and conservation in the protein sequences are to be identified followed by their antigenicity detection. The second objective is to identify a potential peptide vaccine against the omicron variant of SARS Corona virus. Identification of regions with high antigenicity can be useful in synthesizing a peptide vaccine which can be used for immunization of a healthy individual against the specific variant.

Published: June 2023

In the present study, effect of Arbuscular Mycorrhizal Fungi (AMF) on seed germination, nutrient uptake, plant growth, root colonization and chlorophyll content of the Zea mays L. was evaluated. The soil samples collected from maize field (Morgaon, Pune, Maharashtra) were used for the isolation of AMF spores by using wet sieving and decanting method. The International Culture Collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM) worksheet was used for diagnosing the spores. The completely randomized design with three replicates was used for pot culture experiment. The chlorophyll (a, b and total chlorophyll) content from the leaves of the maize plant was successfully determined by Arnon method. Three AMF spores (Gigaspora sp., Acoulospora sp. and Glomus mosseae) were identified and selected for further study. The application of AMF inoculum significantly increases the overall seed germination percent in saline soil (50% and 25% in nonsterile and sterile saline soil) and root and shoot length (13.68 cm and 10.02 cm increase in nonsterile normal soil while 8.93 cm and 11cm increase in nonsterile saline soil) when compared with control. Highest increase in pigment was found in sterile soil inoculated with AMF [chlorophyll a (47.80%), b (47.76) and total chlorophyll (45.56%)]. In root colonization study, different typical AMF structures (such as vesicles, spores, intra and extra radical hyphae) inside the roots of the maize plant were evaluated by microscopic observations. Finally, the nutrient profiling of the soils from all pots showed increased N, P, K, Ca, Fe, Mn, Cu and Zn when compared with control.

The present study evaluated the impact of potassium chloride (KCl) on growth, physiology, photosynthetic pigments and antioxidant enzymes under intercropping system of Gossypium hirsutum L. (RCH-773 variety) and Cajanus cajan (L.) Millsp. (Manak variety). The intercropping was operated in randomised complete block design under different irrigation schedules. The treatments were given as control (full irrigation), early water stress (no irrigation at vegetative stage), late water stress (no irrigation at flowering stage) and stress (no irrigation) along with three potassium concentrations K0, K1 and K2 (0, 20, 60 kg/acre respectively).The sampling was done at flowering stage (120 days after sowing). A long progressive water stress significantly reduced plant height, fresh and dry weight, leaf area, leaf area index, relative water content, membrane stability index and photosynthetic pigments. But application of potassium fertilizer enhanced all these parameters at a great value. The other parameters i.e. electrolyte leakage, superoxide dismutase and catalase increased in stress conditions. However, under potassium application, electrolyte leakage showed a remarkable decrease while the activity of superoxide dismutase and catalase was increased in control as well as in water stressed plants. It clearly shows that potassium is a strong osmo-regulator, maintains cation-anion balance, acts as co-factor for enzymes and helps plant withstanding drought stress conditions.

Neolamarckia cadamba also known as Kadamb, an important traditional medicinal plant belonging to the Rubiaceae family was utilised for treating several diseases. The present study was carried out to quantify secondary metabolites and antimicrobial and antioxidant activities of an aqueous extract (AE) of Neolamarckia cadamba fruits. Different concentrations of plant extracts (1.25, 2.5, 5.0 and 10 mg/disc) have been screened against Gram positive (Staphylococcus aureus and Bacillus subtilis) and gram negative (Escherichia coli and Pseudomonas aureginosa) bacterial strains to detect antimicrobial activity by disc diffusion and minimum inhibitory concentration (MIC) by serial dilution method. AE of N. cadamba fruits with concentrations of 5 and 10 mg/disc showed significant antibacterial activity. The MIC of fruit extract was 3.75 mg/ml for Escherichia coli, Pseudomonas aureginosa and Staphylococcus aureus and 1.875 mg/ml for Bacillus subtilis. FTIR analysis confirmed the presence of alcoholic groups, N-H bending, C-O stretching and aromatic compounds in the extract. The fruit extract was found to exhibit significant antioxidant activity with IC50 = 1.5 mg/ml. Quantitative phytochemical investigation showed the presence of alkaloids (52.00±1.00 mg/g equivalent of atropine), flavonoids (110.33±0.577 mg/g equivalent of rutin), phenols (50.33±0.577 mg/g equivalent of gallic acid) and saponin (22.33±0.333 mg/g equivalent of diosgenin) contents in the extract which might be the reason for its promising antimicrobial and antioxidant potential.

Adequate disposal of solid waste products is one of the uncertainties of mankind. The removal of rotten fruits and vegetables has been an increasing issue in the municipal waste management. The recycling of rotten fruits and vegetables into some value added products will be a promising approach for the future waste management. Many established research works indicate the isolation of Acetobacter species from rotten fruits and vegetables. In the present study, five types (AB01, AB02, AB03, AB04, AB05) of different Acetobacter strains were isolated from a variety of rotten fruits samples. Out of that, we successfully screened out Acetobacter tropicalis jcp OK356208.1 from rotten orange samples. The isolate was identified by both phenotypic and genotypic methods. The isolates were screened for their production capacity of both vinegar and cellulose. Hence, through this present investigation, the isolation of a commercially valuable Acetobacter strain was made possible which can be successfully employed for the production of vinegar and cellulose under optimum conditions. Bacterial cellulose is a biopolymer with magnificent implementations in most of the fields such as biomedical, industrial, food and other diverse biotechnological areas. Exploitation of BC as a wound healing material is one of the keen areas of research field.

High-temperature stress is leading abiotic stress that restricts plant growth, development and yield globally. It reduces plants' productivity, affecting their morphological, physiological, phenological, biochemical and molecular reactions. Major effects of heat stress include impaired membrane systems, denaturation of proteins, enzyme inactivation etc. Responses of plants towards high-temperature stress vary from species to species, with duration and degree of the stress. Plant scientists' main goal is to develop various techniques/practices for satisfying enhanced crop yields and quality. In the cropping system, legumes grains have a significant role in promising food security to the increasing world population. However, legumes are susceptible to several abiotic stresses and heat stress has been known as a primary constraint in limiting their production. Also, the quantity and quality of seed storage proteins are negatively affected by high-temperature stress. Therefore, new approaches to improve legume heat tolerance are critical for reducing yield losses. Plants have several mechanisms for high-temperature stress such as enzymatic and non-enzymatic antioxidant systems, ion transporter and heat shock proteins activated to cope with stress-induced alterations. This review highlights the current research on various responses of plants to heat stress and plant thermo-tolerance mechanisms at the molecular level and illustrates the role of different exogenous molecules in alleviating the heat-induced damages and transgenic methods used to improve plants' tolerance to high temperatures.
Probiotics and human health

Probiotics are living microorganisms which impart beneficial effects to consumers when ingested in a certain quantity. The main probiotic groups include the strains of genera Lactobacillus, Bifidobacterium, Lactococcus and Streptococcus. Probiotics are similar to the naturally found intestinal gut microflora which play an important role in enhancing the human and animal health. Probiotic microorganisms provide various health benefits to human, reduce the blood pressure, decrease the serum cholesterol level, lactose digestion and improve immune response etc. They provide health benefits to the consumers by various mechanisms such as by producing the different postbiotics (bacteriocins, lactic acid), build up the epithelial barrier, fight for binding sites with pathogens on gut wall and thus preventing the infection and enhancing the adhesion to intestinal mucosa. Thus, probiotics having therapeutic values are used for the treatment of various diseases and illness such as allergy, cancer, gastrointestinal disorders, urogenital infections, to reduce obesity, cholesterolaemia and diarrhea. Due to their numerous health benefits, probiotics are gaining more attention among researchers and consumers. More research is needed on probiotics and their action mechanisms which will provide suitable probiotic strain for treatment/prevention of diseases. This review presents the role of probiotic microorganisms in sustaining and improving the health of human being.

This study aims to evaluate the size of the sedimentary carbon sink in the coupling with environmental conditions in a mangrove planted in an abandoned salt pan in Can Gio Mangrove Biosphere Reserve. Sediment samples were collected at four sites chosen based on their dominant plant species. Sediment temperature, pH, salinity, humidity and wet bulk density were measured in field, while the nutrients (NH4+, PO43-) and organic carbon (Corg) concentrations were determined in the laboratory. The results showed that humidity, salinity and bulk density were strongly correlated with Corg concentrations. The amounts of organic carbon stored in the sediments in the dry and wet season were 380 MgC.ha-1 and 552 MgC.ha-1 respectively. Sediment humidity and salinity were the primary factors governing the size of the sedimentary carbon sink. The concentrations of organic carbon and ammonium were influenced by an allochthonous source entering the study area via the tidal creek network.

Silicolytic bacteria are widely distributed playing significant role in silicon cycle. They convert silica into free silicic acid which is taken up by various life forms. Silicases catalyze dissolution of silica into silicic acid. Herein, diversity of silicolytic bacteria in different types of soil samples and wild grasses was studied by plate assay using different media. Silicase activity of two isolates from two different habitats was compared. The results revealed that silicolytic bacteria were abundant in number but their population varied in different habitats. Paddy field soil and wild grasses harbored the highest population of silicolytic bacteria. Different screening media were evaluated. Pigment and exo-polysachharide were also produced by some silicolytic endophytes. Statistical analysis showed that silicolytic bacterial population in paddy soil and wild grasses was significantly abundant as compared to that in dumping land and contaminated soil around heavy metal industries.

El objetivo de la presente investigación fue realizar una redistribución de inventarios basada en la clasificación ABC de mercancías y evaluar la mejora en los indicadores de desempeño del almacén en una empresa productora de alimentos en Sinaloa, México. La metodología empleada constó de cuatro etapas: diagnóstico de la situación actual; generación de propuestas de redistribución de inventario basada en la clasificación ABC; implementación y también evaluación de resultados. Se midieron indicadores de desempeño de rotación y duración de inventario antes, así como después de la implementación. Se obtuvieron resultados favorables en los cinco productos; sobresalió el inventario de manteca, en donde incrementó su rotación semanal en 32,92 unidades, mientras que su duración dentro del almacén se redujo dos días. Para recolectar la información, se empleó la observación, el conteo de unidades de inventario en físico aunado a la verificación en el sistema. Concluimos que la gestión de inventarios es una actividad clave para cualquier organización, sobre todo para las empresas de giro alimenticio, dado que los productos son perecederos, propensos a generar mermas por una inadecuada gestión o rotación.
Architectural Absence

Published: June 2023

This research through design addresses the growing need for solitude, stillness, and connection to vast natural spaces by exploring the intangible heritage of Awaroa / Godley Head…Taking this location as a testing ground for architectural dialogue, the project seeks to create a series of architectural interventions that evoke the former past of the site, that explore typological precedent, and that address a perceived disconnect within the existing architecture around the site.

The objective is to make the history of the place visible and tangible in a way that allows people to respond emotionally.

The project engages with the history, landscape, memories, and narratives of the site, and investigates the distinctionbetween a new intervention and a heritage artefact.

Drawing on the framework of Swiss Architect Peter Zumthor, who stimulates an emotional awareness of the history of a place through his architecture, a triad of design outcomes are developed that aim to evoke emotions powerful enough to move visitors beyond their usual mode of passive perception, and to acquire a deeper understanding of the site.

Through this process, an architecture of reverence is developed that harmonises these elements and offers a new experience of place.

Authors: Andacht Fernando , Prieto Marina
Published: June 2023

El artículo utiliza un abordaje semiótico para desarrollar un análisis de un fenómeno comunicativo central de las sociedades contemporáneas: el uso de las redes sociales (específicamente Instagram, Twitter y WhatsApp) de ambos protagonistas de la serie de Netflix You – Joe Goldberg y Beck Guinevere. Procuramos estudiar el modo en el que participan en procesos comunicacionales con la tecnología disponible en las redes sociales. El enfoque es inmanente: no se considerará ni la recepción, ni el aspecto económico o histórico de esta producción audiovisual, sólo su dimensión sígnica: Â¿Cómo funcionan los signos en el uso cotidiano de las redes sociales en esta ficción? Â¿Cómo se interpreta el sentido de lo que ellas ofrecen a estos personajes? Â¿Qué cambios han introducido los medios digitales en el comportamiento comunicacional, en los modos de generar sentido? Desde un abordaje semiótico, analizamos un elemento universal de la condición humana: el uso de signos para comunicarse.
