Unlocking the Potential: A Comprehensive Analysis of the Technological Properties and Consumer Perception of Shampoo Enriched with Patchouli Extract and Allantoin Amidst a growing shift towards eco-friendly choices in personal care products, the challenge of formulating herbal shampoos with efficacy comparable to synthetic counterparts persists. This study investigates the potential of incorporating patchouli extract and allantoin as additives in anti-dandruff shampoo formulations, assessing their impact on the technological properties of the product. With limited research on their efficacy, our investigation contributes valuable insights to the development of effective and consumer-friendly shampoos targeting dandruff concerns. Physicochemical characteristics (pH, surface tension, texture) were evaluated, alongside specific quality assessments such as wetting time, dirt dispersion, foaming, and cleaning action, in in vivo consumer research. Shampoo formulations incorporating 0.5% Patchoul’Up™ and 1% allantoin exhibited acceptable properties. However, the addition of plant-derived ingredients resulted in a beneficial decrease in surface tension (5.87%). Nevertheless, a decrease in cohesiveness (18%) over a 5-month period resulted in rheological changes, indicating potential instability (p &lt; 0.05). While the consumer evaluation aligns with laboratory findings, continuous research is essential to ensure stability and validate the anti-dandruff potential of the formulation, both in vitro and in vivo. This involves expanding the number of volunteers, with a specific focus on individuals experiencing dandruff concerns, to assess the shampoo’s efficacy and impact on diverse user experiences.

Optimization of paracetamol tablets using Quality by Design principles and the INQA neural network En la industria farmacéutica, la implementación de herramientas innovadoras para reducir costos y tiempos en el desarrollo de medicamentos es crucial. La formulación del medicamento juega un papel fundamental, enfocándose en la compatibilidad entre el principio activo (API) y los excipientes, lo que se determina en la fase de preformulación. Las guías ICH Q8, Q9 y Q10 son esenciales para optimizar estos procesos, ya que permiten anticipar y evitar errores mediante un análisis científico y la identificación de parámetros críticos. Para facilitar esta comprensión, se desarrolló una matriz de riesgos que identifica los atributos críticos de calidad (CQA), los atributos críticos de material (CMA) y los parámetros críticos del proceso (CPP). Se realizó una revisión bibliográfica sobre diversas formulaciones de acetaminofén, seleccionando excipientes como crospovidona, almidón y estearato de zinc, y se calculó la concentración adecuada utilizando un manual de excipientes. El entrenamiento de la red neuronal se llevó a cabo con un conjunto diverso de datos, aplicando un diseño experimental que desarrolló un rango de concentraciones, permitiendo a la red responder adecuadamente a variaciones. Durante el desarrollo de tabletas, se realizaron pruebas del polvo (como el índice de Hausner y el índice de Carr) y controles de proceso para evaluar la dureza, uniformidad de peso y dimensiones de cada tableta, según la matriz de riesgos. Finalmente, se implementó una red neuronal entrenada con distintos modelos, observando que aquellos relacionados con la crospovidona y la uniformidad de peso presentaron un R2 superior a 0.6, lo que indica que la red puede predecir los modelos de formulaciones.

The Efficiency of Drip Irrigation vs Flood Irrigation in Coconut Production – An Agro-economic Study in Tiruppur District of Tamil Nadu, India Coconut also called as ‘Kalpavriksha’ in Sanskrit, which means tree of heaven, because of its usefulness from each part of the tree. India is one of the leading producers of coconut in the world as India stands third place in terms of area under coconut cultivation followed by Indonesia and Philippines. Though coconut has several uses, it requires high amount of water for growth and it is about 800 to 1000 mm annually. The study was aimed to find the irrigation method, which would be efficient for coconut cultivation. Hence, to compare the yield, profitability and efficiency of coconut production among drip irrigated and flood irrigated farms, a study was formulated in Tiruppur district with a sample of 40 drip irrigated and 40 flood irrigated farms constituting a total of 80 coconut farms. The study found that drip irrigation reduces weed growth, pest incidence, etc, which leads reduced labour use and contributes to increased net returns. The net returns was also comparatively low in flood irrigated farm category Rs. 88962.76, as against the net return of Rs. 112374.14 in drip irrigated farm category. The difference in net returns between flood and drip irrigated farms was Rs. 23411.38 and it was about 20.83 per cent higher than net returns obtained from flood irrigated coconut farms. The results of benefit cost ratio was higher in drip irrigated farm category (1.51) as compared to flood irrigated farm category (1.42). This might be mainly due to the increased yield obtained in drip irrigated farms than flood irrigated farms due to better efficiency of production. The mean technical efficiency was found to be 76.58 per cent and 87.66 per cent in flood irrigated and drip irrigated coconut farms respectively. It can be concluded from the analysed results that the coconut production, profitability and efficiency is high in drip irrigated farms and hence the study recommends for adoption of drip irrigation for coconut cultivation, leading to sustainable water use as by the sixth sustainable development goal.

Using a confined space to boost the driving amplitude of pulsating bubbles to facilitate jetting Abstract A bubble collapsing near an interface may result in the formation of a liquid jet protruding from the distal bubble side, through the bubble, towards the interface. Ultrasound assisted jetting has been observed when subjecting, by approximation, infinite fluids to acoustic amplitudes above the inertial cavitation threshold, limiting the possibility of ultrasoundguided, bubble-assisted drug or gene delivery. However, the vascular system can be regarded as a finite fluid. The purpose of this study was to investigate the feasibility of lowamplitude jetting for fluid containing biocompatible cavitation nuclei, by placing the region of interest in a confined space to ensure a standing wave field. Droplets of Quantison TM ultrasound contrast agent were pipetted into a Perspex cylindrical compartment of 8-mm diameter and 2-mm height, which was part of an imaging system. The contrast agent was subjected to 3-cycle ultrasound pulses with a centre frequency of 1MHz whilst being observed at a frame rate of ten million frames per second. Jetting was observed to occur with microbubbles nucleated from the contrast agent in an acoustic regime whose free-field mechanical index was 0.6. Empirical curve matching showed a pulse amplification by a factor of six owing to the chosen geometry. Visible jet lengths of twice the bubble radius on the verge of collapse were measured. Owing to the confined space, the local acoustic amplitude was amplified to surpass the cavitation threshold. This finding is of interest for medical ultrasonic applications where the local environment comprises reflectors.

Determining the rational structure of multilayer technical fabric for woven power clamps The object of research is multi-layered technical fabrics for woven power clamps. A task to determine the rational structure of a multi-layer technical fabric for power clamps has been solved, which makes it possible to achieve an effect when introduced into production through the minimization of raw material costs and the reduction of energy costs for manufacturing a unit of products. The value of the beating force, the tension of warp threads of the outer protective layers, the force layers, the warp threads for connecting the outer protective layers, and the force layers for two structures of multilayer technical fabric were studied. A comparative analysis of conditions for the formation of two multilayer fabrics from polyamide threads was carried out and a multilayer fabric with the most rational structure was selected, the formation of which would require less technological effort. Experimental studies have made it possible to build regression dependences on determining the influence of the initial tension of warp threads of the outer protective layers on the beating force value. The joint effect of the size of an overstep and the different tension of a shed on the beating force value was established, depending on the structure of a multilayer technical fabric. It is shown that when the tension of warp threads of the outer protective layers increases, the beating force value increases. A value of the tension of warp threads in outer protective layers, force layers, warp threads for connecting the outer protective layers and force layers in the position of an overstep and at the moment of thread beating was determined. Analysis of regression dependences will make it possible to determine the optimal loading parameters of the loom. It has been proven that the beating force value is affected by the structure of a multi-layer technical fabric and the tension of warp threads in outer protective layers. The improved multi-layer technical fabric is used for laying pipes with an external factory-made polyethylene coating Power (physics) ; Structural engineering ; Engineering ; Materials science ; Mechanical engineering ; Composite material ; Computer science ; Physics Textile materials and evaluations

Whose fault is it anyway? SILC: Safe Integration of LLM-Generated Code In modern software development, multiple software components, often sourced from different contributors, including AI assistants, are combined to create a cohesive system. Although these components might each be individually safe, their composition might not be so. At the core of this issue is often a misalignment between the requirements and assumptions made by each component. Once discovered it is important to determine which component is accountable for addressing the misalignment issue and to prevent its occurrence in the future. In this work we propose SILC, a framework for localising fault, i.e. blame, and for assigning sanitization obligations to prevent memory issues resulting from the composition of multiple software components. In particular, we show the role Incorrectness Logic could have in automatically extracting implicit non-functional assumptions in auto-generated code and render them explicit in order to detect misalignment with the requirements in existing code. In other words, we are looking at the problem of code comprehension from a perspective focused on safety properties rather than the traditional approach centered on functionality. To do that, we enhance Incorrectness Separation Logic with capabilities for fault tracking and sanitization insertion. We show the benefits of this framework by running experiments on millions of lines of code from open source projects where parts of existing functionality are regenerated by AI assistants. We empirically show that AI assistants produce unsafe code and demonstrate the utility of our framework in proposing appropriate blame and sanitization obligations.

On the choice of functionals obtained from the predictive distribution of future retweet counts The prediction of future retweet counts for tweets shared on Twitter has been a topic of immense interest recently. Numerous models have been proposed for such prediction, with their accuracy being assessed using certain choices of evaluation metrics. Admittedly, the majority of predictive models involved have overlooked the problem on the use of theoretically optimal functionals as point predictions and resort to employing options which are more accessible like the predictive mean. This motivates our discussion wherein the practicality of using theoretically consistent functionals with respect to the evaluation metrics considered is put forth. We discuss how the median of order (–1) and harmonic median are optimal in theory relative to the mean and median absolute percentage errors respectively, followed by highlighting in contrast how predictive models extant in the literature may suggest otherwise. Specifically, using a Poisson model supported by a large corpus of Twitter data, our numerical experiments indicate that predictions based on different functionals derived from the predictive distribution do not vary materially across the different metrics used, although predictions stemming from the predictive mean are slightly yet consistently more accurate than those based on the other functionals. We further outline how consistent functionals can be obtained accordingly under the settings of more complex predictive models.

Defining patterns in the intensification of hemp stalk retting processes The object of this study is the technological operations of primary hemp stalk processing, factors that intensify the retting process, and stalk crushing. The task addressed was the identification of technical and technological solutions that would enable intensification of the production processes for hemp retting. Based on the research results, it was established that placing the flattened stems in natural and polypropylene bags, compared to cellophane bags, accelerates the preparation time of retted stalks in a vertical position by 1.19 times, and in a horizontal position by 1.38 times. The retting time for horizontally placed crushed stalks with weekly moistening twice a week is 2.16 times shorter than for uncrushed ones. It was determined that the process of crushing pre-prepared and cured stalks, whether in a vertical or horizontal position, allows for a significant reduction in retting period by 2.14 times, and for freshly cut stalks – by 1.27 times. The intensity of the reflected light flux changed in the case of reaching the retting phase for unflattened stems with their vertical placement from the initial 32.0 lux to 18.0 lux. In flattened stems under the conditions of their vertical placement – from 50.7 to 16.3 lux, respectively. In the case of horizontally placed crushed stalks, the light intensity at the retting phase was 20.3 lux. The lowest fiber breaking load value of 5.0 daN was established for the retted stalks obtained from freshly cut flattened stems in a vertical position, as well as in non-flattened stems in the vertical (7.0 daN) and horizontal (3.5 daN) positions Retting ; Stalk ; Cellophane ; Pulp and paper industry ; Materials science ; Composite material ; Engineering ; Horticulture ; Biology Natural Fiber Reinforced Composites ; Innovations in Concrete and Construction Materials ; Advanced Cellulose Research Studies
