A concise approach for interpreting the removal kinetic of 2,4-D by carbonized peanut shell

The present study displays the adsorption characteristics of dichloro phenoxy acetic acid (2.4-D) on biomass-based peanut shell (BPC) carbon. Experiments were conducted by varying some parameters like concentration, pH, and temperature. 2,4-D adsorption uptake was increased from 0.504 to 3.826 mg/g with rising concentration from 1 µg/mL to 5 µg/mL and giving the highest adsorption at acidic pH. 1.605 mg/g uptake was obtained at pH 2.7. The data were in good harmony with Langmuir, Freundlic, Dubinin-Radushkevich (DR), and Generalized isotherms. The monolayer adsorption capacity was found as 42.62 ± 0.3257 mg/g. The kinetic was governed by the first-order kinetic. Various kinetic models were employed and particle diffusion was predominated for 2,4-D adsorption. Thermodynamics were explained in detail. The mean adsorption energy (E) was shown by the physical sorption, and Gibbs energy was the indicator of the spontaneous nature of the adsorption. Standard enthalpy, entropy, and Gibbs values were recorded as 5.064 ± 139.84, 18.849 ± 0.148, and 0,7414 ± 0.0943 J/mol. The results showed that BPC was an eco-friendly and cost-effective material.

The Color Harmony Estimation Model Construction Based on Two Layers of MLE and BPNN in the Color Matching Field

In the field of art, color matching is widely used in various art designs, such as images, posters, clothing, and interior home design. Among them, harmonious color matching is the decisive factor in whether a design is popular or not. To solve the problem of estimating color harmony, this study analyzes from the perspective of color pairs and uses the two-layer maximum likelihood estimation method to make preliminary predictions of color harmony by statistically modeling paired color preferences in existing datasets. After obtaining the preliminary estimation of color harmony, multiple linear regression is selected for denoising processing. Subsequently, the preliminary prediction results were refined using a backpropagation neural network, extracting various color features in different color spaces, and ultimately obtaining accurate harmony estimates. The results indicate that, compared with existing methods, the proposed method can simulate the aesthetic cognition of different users towards different color themes. Under the same statistical method, the model can maintain good harmony estimation and experimental results. This method can promote the development of related research fields, such as quickly evaluating the color harmony of an image, and one click color changing in scenes such as clothing, home, 3D models, etc. according to different user needs.

How to Collaborate Without Burning Out

Abstract: This article examines the challenge of collaboration burnout in the modern workplace and provides recommendations for leaders to facilitate productive collaboration without overwhelming employees. Drawing on research and the author's experience as an organizational consultant, key drivers of burnout are identified as excessive and inefficient meetings, unclear collaboration expectations, and poor work-life integration. Five practical recommendations are outlined for leaders to mitigate these risks, including establishing clear collaboration guidelines, fostering an efficiency culture, empowering autonomy through flexibility and trust, encouraging flexible work arrangements, and modeling good work-life harmony. The recommendations are brought to life through examples of their application in contexts like law firms, software companies, and advertising agencies. The article argues that a balanced, human-centered approach to collaboration considering employee well-being is critical for organizations to sustain engaged, innovative teams over the long-term.

Correlations of mixed convection in a double lid‐driven shallow rectangular cavity: The case of non‐Newtonian power‐law fluids

AbstractThis work provides an analytical and numerical assessment, complete with correlations, of mixed convection in a double lid‐driven shallow rectangular enclosure, which confines non‐Newtonian fluids of the Ostwald–de Waele type and which a uniform thermal flux heats. The finite volume method with the SIMPLER algorithm is the numerical method used to solve the governing partial differential equations along with the boundary conditions, where the parallel flow concept is the analytical approach. In the limits of the explored values of the governing parameters of this study, which are the Rayleigh number, the Peclet number, and the behavior index, the results obtained by these approaches appear to be in good harmony. On the basis of the results obtained by these approaches, we established helpful correlating relations between the governing parameters to realize the contribution of mixed convection to heat transfer. This leads to the finding that the ratio Ra/Pe2+n is the mixed convection parameter, which is the key to distinguishing the three convective flow modes. On the basis of this parameter, which allows the transition from one regime to another, it is possible to identify the zones that designate the predominance of natural, forced, and mixed convection. The limits of these latter depend on the behavior index, n, which is diversified from 0.6 to 1.4 to account for shear thinning (0 < n < 1, low apparent viscosity, high fluid flow, and high heat transfer rate), Newtonian (n = 1), and shear thickening (n > 1, high apparent viscosity, slow fluid flow, and low heat transfer rate) fluids. On the other hand, the study presents and interprets the influences of the steering factors on heat transfer and fluid flow.

The Effect of Motor Dual -Task Balance Training on Balance and Gait of Elderly Women

BACKGROUND: Aging in its broadest sense is the continuous and irreversible decline in the efficiency of various physiological processes. India has second largest number of elderly (60+) in the world. One of the most common problems of elderly is fall. They are the cause of accidental death among people over 65 years of age and account for significant mortality and morbidity, including fractures, impaired mobility and decreased quality of life due to fear of falling and death. Balance is dynamic phenomenon that requires stability and mobility to be a good harmony and in order to properly maintain body balance, the ability to integrate the neurological and musculoskeletal system is important. Balance control is a necessary component of stable walking. Dual-task training is defined as the ability to perform two or more cognitive and motor activities simultaneously while maintaining postural control. AIMS AND OBJECTIVES: To study the effect of motor dual-task balance training on balance and gait of elderly women. METHODOLOGY: Thirty females were randomly selected according to inclusion and exclusion criteria and was divided into two groups – Group 1: Experimental group and Group 2: Control group. Both the groups were assessed for the berg balance scale and dynamic gait index. These parameters were assessed before the start of the program as pre-test values and at the end of 6 week as post-test values. Group 1 received motor dual task balance training and Group 2 conventional balance and gait training. RESULT: The mean age of group 1 was 67.4 years and group 2 was 67.07 years.

KEY WORDS: Fall, Elderly, Balance, gait, BBS, DGI, motor dual task balance training, conventional balance and gait training.

Buckling behavior of simply supported tapered square plates

Buckling is one of the important design parameters for the design of plate structures. The critical buckling loads and buckling coefficients for a series of different tapered plates are investigated. Buckling analyses of square plates are performed by changing different types of thickness variation by using ANSYS finite element software. Plates are assumed to be thin plate. The loading types and taper ratio of the simply supported square plates considerably affect the critical buckling loads. Some analyses results are compared with the literature results and presented in the form of graphs and tables. It is concluded that the analyses results are in good harmony with the literature results. The graphics proposed in this study could be useful for designers. The formulas obtained from the graphics gives the buckling coefficients for calculating the critical buckling loads for tapered plates with different loadings.

Factors influencing the cruisers in recommending onshore excursions in Gran Canaria

This paper investigates which elements are the ones that most influence the cruise passenger to recommend the onshore excursions, offering relevant information that could help all stakeholders (cruise firms, local operators, politicians, etc.) to better design/adapt shore excursions to the expectations of the cruise passengers, increasing the positive impact of this activity in the destination. The latter is essential for the existence of a good harmony between the cruise ships visiting a destination and the population living there. To this aim, an ordered logit model was estimated using a sample of 1,059 questionnaires obtained during the period 2018–2020. The results have shown that cruise passengers are more likely to recommend the onshore excursions if their expectations regarding the excursion have been covered, they have perceived a good quality/price ratio and have had a satisfactory tour guide service. Moreover, the fact that the cruisers aged between 45 and 55 are less likely to recommend excursions could suggest that the design of existing excursions could be improved by being tailored by demographic characteristics (i.e., aged-oriented) or even by offering different alternatives for each group during the shore excursion when possible. The results could be useful to all stakeholders when designing excursions to increase the positive impact of this activity on the destination.

Daily geomagnetic variations under variable IMF/solar conditions and their connection with underground conductivity changes in Japan

Fluctuations in Solar Wind (SW) and Interplanetary Magnetic Field (IMF) significantly affect the Geomagnetic Field (GF) measurements particularly during extreme space weather events. The current study investigates the variations of horizontal (H), vertical (Z) geomagnetic components under quiet and disturbed IMF and solar conditions as well as the effect of underground conductivity on the stationary geomagnetic measurements in Japan. Results of data analysis show that the response of the GF to IMF and solar parameters fluctuations is variable. The H- and Z-components were in good harmony with high visual correlation along a latitudinal profile across Japan during quiet times. On the other hand, during the disturbed times related to a Coronal Mass Ejection (CME) launched on 13 May 2005, the GF components varied with the disturbance of IMF and solar parameters. The H-components showed highly correlated variations with a significant reduction along the examined profile due to intensified ionospheric currents, while the Z-components recorded in the northern part of Japan showed abnormal daily variations pattern (positive daily variations) with an enhanced amplitude which is opposite to the normal behavior of daily variations recorded in the central and southern parts of Japan (negative daily variations). The observed enhanced and abnormal daily variation of Z-components in north Japan, which we consider a remarkable observation here, is possibly linked with underground conductivity anomaly in this region.

The Nonlinear Bending of Sector Nanoplate via Higher-Order Shear Deformation Theory and Nonlocal Strain Gradient Theory

In this context, the nonlinear bending investigation of a sector nanoplate on the elastic foundation is carried out with the aid of the nonlocal strain gradient theory. The governing relations of the graphene plate are derived based on the higher-order shear deformation theory (HSDT) and considering von Karman nonlinear strains. Contrary to the first shear deformation theory (FSDT), HSDT offers an acceptable distribution for shear stress along the thickness and removes the defects of FSDT by presenting acceptable precision without a shear correction parameter. Since the governing equations are two-dimensional and partial differential, the extended Kantorovich method (EKM) and differential quadrature (DQM) have been used to solve the equations. Furthermore, the numeric outcomes were compared with a reference, which shows good harmony between them. Eventually, the effects of small-scale parameters, load, boundary conditions, geometric dimensions, and elastic foundations are studied on maximum nondimensional deflection. It can be concluded that small-scale parameters influence the deflection of the sector nanoplate significantly.

The set of four ternary coordination compounds of terbium were prepared with diketone 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione (TFDH) and four different neutral ligands (L) having formula [Tb(TFDH)3L]. Resulting compounds were characterized using different techniques including NUV absorption studies, photoluminescence (PL) spectroscopy, electrochemical and thermal analyses. PL spectra confirmed the green luminescence of synthesized complexes by exhibiting characteristic dominant 5D4 → 7F5 peak around 545 nm. Electronic and optical energy gap values lying at ∼3.5 eV reveals their potential to use in semiconductor materials. All the spectral results are in good agreement with each other and highlight their utility in lighting, biomedical imaging and sensors etc.

Synthesis, characterization and DFT studies of fluorinated aryl derivatives: Electronic and optical responses

The current study was designed to synthesize biaryls compounds viz; 2-(3,4-difluorophenyl) benzothiophene (DFPBT), 3-(3,4-difluorophenyl) quinoline (DFPQ) and 1-(3,4-difluorophenyl) naphthalene (DFPN) by means of Suzuki-Miyaura Pd(0)-catalyzed protocol. Different characterization techniques were used to evaluate the structure of desired synthesized compounds viz; H1NMR, C13NMR, FT-IR and UV–Vis analyses. Besides, DFT computations were carried out at B3LYP/6–311++ G(d, p) functional to gain an insight of key electronic properties of the synthesized compounds. The natural bonding orbital (NBO) analysis showed that molecules of these compounds should interact quite noticeably with each other in the solid phase and with polar solvent molecules. The FMO findings revealed that the ∆E value are in order; DFPN > DFPQ > DFPBT. Accordingly, DFPBT exhibited better NLO properties and possessed a slightly strong electron transfer potential than DFPQ and DFPN. A good harmony between experimental (296.4, 304.7 and 298.4 nm) and simulated (306, 305 and 298 nm) UV–Vis values was investigated in studied compounds. Furthermore, multiple functional (M062X, CAM-B3LYP, HF, M06, B3LPY, and LCBLYP) with 6–311++G(d, p) basis set were used to investigate the total dipole moment, hyperpolarizability βtot and average polarizability ⟨α⟩ values. The average polarizability ⟨α⟩ values of DFPBT, DFPQ and DFPN were 5.7, 5.7 and 5.5 times greater than urea i.e., ⟨α⟩=34.055 a.u, while, the βtot values were 5.8, 7.8 and 6.1 times more than the total values of urea. i.e., 90.527 a. u, respectively. These efficient behavior of NLO in synthesized compounds indicated the significant use of these compounds in optoelectronic devices.

Comparison illustrates that theoretical results obtained by us are in good harmony with experimental results.

Análise da coerência entre Dimensão Vertical de Oclusão (DVO) estabelecida clinicamente e por análise cefalométrica. Estudo transversal

Abstract Introduction Determining the VDO is one of the most important requirements in restorative dentistry, as it is crucial for good aesthetic and functional harmony. However, due to its empirical nature, a combination of methods is clinically recommended, and cephalometric analysis is one of the procedures available. Objective The objective of this study is to evaluate the coherence between VDO clinically established with VDO determined in Seraidarian-Tavano cephalometric analysis in completely edentulous patients. Material and method Registrations were carried out on completely edentulous patients using a combination of clinically recommended methods (metric method from VDR, swallowing method, and facial fullness method). With the registration in the mouth, lateral cephalometric X-ray images were taken with the patient in occlusion for cephalometric analysis. Result The sample consisted of 18 patients, 11 females (61.1%) and 7 males (38.9%) with a mean age of 65.8 ± 1.9 years. For the 18 patients, the mean measurements of the upper and middle angles were 54.1 and 54.0, respectively. No statistically significant difference was found between the two angles (p 0.772). These results show that the VDO considered ideal from a clinical point of view was confirmed by the cephalometric analysis used. Conclusion Based on the data, it seems fair to conclude that the tested cephalometric analysis can be a method used to assist the clinical determination of VDO.

Exploring the photovoltaic properties of naphthalene-1,5-diamine-based functionalized materials in aprotic polar medium: a combined experimental and DFT approach.

In this study, a series of naphthalene-1,5-diamine-based donor chromophores (ND1-ND9) with A-D-A architecture was synthesized through a condensation reaction between amines and substituted aldehydes. Various spectroscopic techniques i.e., FTIR, UV-Vis, 1HNMR and 13CNMR were performed for structural elucidation of naphthalene-1,5-diamine-based chromophores. Accompanying the synthesis, quantum chemical calculations were also accomplished at MPW1PW91/6-311G (d,p) functional of DFT/TD-DFT approaches to explore the photovoltaic properties of ND1-ND9 compounds. A comparative study between experimental and DFT results of vibrational and UV-Vis analyses showed a good harmony. All compounds showed band gaps in the range of 3.804-3.900 eV with absorption spectra in the UV region (397.169-408.822 nm). Frontier molecular orbital (FMO) findings revealed an efficient intramolecular charge transfer (ICT) from the central naphthalene-1,5-diamine-based donor core towards terminal acceptors. This significant charge transfer was also supported by the density of states (DOS) and transition density matrix (TDM) maps. All synthesized chromophores showed lower exciton binding energy values (E b = 0.670-0.785 eV), illustrating higher exciton dissociation rates with greater charge transfer in the studied chromophores. A reasonable harmony was obtained by comparative investigations of a standard hole transport material (HTM), Spiro-OMe TAD, with ND1-ND9 compounds, which illustrated that these synthesized chromophores might be considered as good HTMs. Therefore, all analyses indicated that the naphthalene-1,5-diamine-based chromophores might be utilized as efficient photovoltaic materials.

Application of Z-numbers theory to study the influencing criteria in underground mining method selection

The purpose of this study was to prioritize and determine the importance of effective factors in selecting the appropriate underground mining method (UMM). This study also evaluates the uncertainty and various life-threatening/mortal and financial risks associated with these criteria. In the present study, 43 influencing criteria for underground mining method selection (UMMS) were identified and classified into two main groups. Then, a model was proposed by employing the Z-numbers theory (Z-NT). A total of 25 specialists from around the world were approved for the study, and 10 of them returned questionnaires. By applying Z-numbers and using the proposed model, the uncertainty of the experts' opinions was highly reduced. Finally, the model was applied to the Angouran Lead and Zinc (L&Z) Mine in the northwest of Iran for verification. The findings indicate that within every group of criteria, the weighting of factors determined in this study is in good harmony with the key factors considered in the selection of mining method at Angouran Mine. Also, based on the technical reports of Angouran Mine, the mine is facing various risks. Therefore, this research has also been examined from a risk assessment perspective, and the findings of the proposed model have been put against the factors influencing the various risks in the Angouran Mine. The results show that the factors that have the highest weight in risk proneness are stope collapse, underground water inflow into the stope, and machines’ downtime.

Electrochemical, spectroscopic, kinetic and surface analysis of the inhibitory performance of Alcian blue dye for copper corrosion in sulfuric acid solution

The use of corrosion inhibitors is considered as the supreme dominant approach to control the damage of metallic corrosion. Organic dyes are extensively employed as inhibitors for the corrosion of various metals and alloys in diverse media. Herewith, Alcian blue dye (ABD) was selected to investigate its inhibitive characteristics against the corrosion of copper in 1.0 M H2SO4 solution at 298 K. This investigation was monitored by various chemical, electrochemical, and spectroscopic techniques. The results indicated that the examined dye is a proficient inhibitor for the corrosion of copper in 1.0 M H2SO4 solution and its inhibition efficiency (% IE) was increased with augmenting its concentration and diminished with rising medium temperature. The high anti-corrosive ability of the selected dye was attributed to its adherent adsorption of such dye on the Cu surface and follows Langmuir isotherm. Thermodynamics and kinetics of corrosion of copper and its inhibition by the examined dye were inspected. The mechanisms of copper corrosion in H2SO4 solution and its inhibition by ABD were proposed. The obtained results illuminated that the examined dye acts as a mixed-type inhibitor with cathodic precedence. Finally, all gained results with respect to % IE values of the dye were compared and designated a good harmony between all applied techniques.

Non‐Newtonian laminar pulsating heat and fluid flow in plane duct

AbstractIn the present study, laminar pulsating power‐law momentum and heat transfer in a uniformly heated plane duct is studied analytically. Assuming that fully developed conditions exist both hydrodynamically and thermally, a perturbation series method is utilized to derive analytical solutions for the momentum and energy balance equations, and the amplitude is prescribed as the perturbation parameter. For varying values of the power‐law index (), representing pseudoplastic, Newtonian, and dilatant fluids, effects of dimensionless amplitude () and frequency () on periodic and period‐averaged friction factor and Nusselt number are obtained. The results obtained for Newtonian fluid are shown to be in good harmony with the corresponding findings in the open literature.

ISTIGFAR THERAPY AS SELF-CONTROL

Self-control is one of the personal competencies that every individual needs to have. Good behavior, constructive, and harmony with others are influenced by the individual's ability to control himself. Self-control that is well-developed in individuals will help individuals resist behavior contrary to social norms. Self-control is an individual's ability to inhibit or prevent an impulse from appearing in the form of behavior that violates or is contrary to moral standards. Self-control as organizing, guiding, regulating, and directing forms of behavior that can lead individuals to positive consequences. According to the researcher, istighfar is suitable for the client because of the meaning of asking for forgiveness from all mistakes. The problem experienced by the client is one of the mistakes, namely (cursing at his friends). This Istighfar also mentions that God is the best of human guardians. Someone asks forgiveness from Allah and asks for protection and care to protect him from bad and despicable traits. Istighfar is very important for humans. Not only because humans have a more excellent opportunity to sin, but also because Allah SWT repeatedly commands both through His words in the Qur'an and the mouth of His messenger (Rasulullah SAW).

A high-sensitivity wearable flexible strain sensor based on three-dimensional twist-like network structure

With the rapid development of the flexible electronics field, flexible pressure sensors are widely used inwearable devices, medical monitoring and other fields. However, it is still a huge challenge to design a sensor with highsensitivity, low cost and a simple manufacturing process. In this work, we report a flexible strain sensor based on discarded mask straps (MS) with a unique three-dimensional (3D) twist-like network structure. Multi-walled carbon nanotubes (MWCNTs)/carbon nanoparticles (CN)/MS composites were prepared by a simple dip-drying method and encapsulated using a medical Polyurethane (PU) film. It is founded that the fabricated MWCNTs/CN/MS/PU flexible strain sensor (MCMP-FSS) exhibits a high gauge factor (GF) of 13,928 and advanced performance with a large sensing range of 0%–72%. Moreover, good water-repellent harmony and various types of stimuli over 1000 cycles were obtained for the MCMP-FSS. Benefiting from the unique 3D twist-like network structure and the MWCNTs/CN synergistic conductive network, MCMP-FSS also has broad application prospects in the fields of human motion detection, encrypted communication, and natural human-robot interaction.

Investigations on tissue equivalence of selected biomaterials through radiological parameters

The objective of this work is to investigate some commonly available tissue mimicking biomaterials for imaging phantoms and different radiation therapies utilizing gamma-photons, protons, electrons and neutrons. The various interaction parameters employed in radiology like computed tomography number, buildup factor, mass attenuation coefficient, stopping power and fast removal cross-section have been computed through various software programs namely Phy-X/PSD, XCOM, SRIM and NIST: ESTAR database. The mass attenuation coefficient values obtained from the two methods i.e. Phy-X/PSD and XCOM support each other with maximum relative difference of 1%, thus validating the use of new software for biomaterials. The tricalcium phosphate and monocalcium phosphate anhydrous are found to be the best phantom material having attenuation values 0.410 and 0.319 cm2/g and computed tomography numbers 5225.3 and 2426.1 at photon energy 59.5 keV, which are in good harmony with that of enamel and cortical bone respectively. Similarly, dicalcium phosphate anhydrous/monocalcium phosphate monohydrateare appropriate biomaterials for enamel/cortical bone over useful MeV energy range for electron as well as neutron therapy.
