Opis:
Background. The consumption of food supplements is increasing. This evolution is due to several factors, including nutritional deficiencies in the population, a sedentary lifestyle, and a decrease in physical activity. In addition, stress and an active lifestyle led to several dysfunctions (fatigue, deconcentration) that food supplements can help to overcome. Objective. This study aimed to determine the profiles of food supplement consumers in the Fes-Meknes region (Morocco), distribution, and production of these products. In addition, this survey aimed to evaluate consumers’ knowledge of food supplements as part of their self-medication. Material and methods. The present study was conducted in the form of a survey using a questionnaire composed of two parts. The first part provides information on the socio-demographic status of respondents, including gender, age, and level of education. The second part concerned various information on the consumption of food supplements. Results. The results obtained showed that of the 498 subjects, 68.88% declared that they had already consumed the food supplements. The study revealed the predominance of the female gender at 69.68% and the age group 21-30 years (80.32%). Among the reasons for consumption, improving general health comes first with 56.29%. Our results also showed high consumption of vitamins (44.04%) and minerals (24.79%), next come proteins and plant extracts at 16.62% and 14.54% respectively. The consumption of food supplements is most often done on the advice of a doctor or dietician with 43.60%, and the pharmacy and para-pharmacy remains the main distribution channel at 75.78%. Conclusion. The present survey allowed us to update the current situation of food supplement consumption and a way of regulatory monitoring and more control for an organization of the sector.

Opis:
For the first time, simultaneous influences of porosities, tangential constraints of boundary edges, surrounding elastic media and elevated temperature on the buckling and postbuckling behaviors of a functionally graded toroidal shell segment are investigated in this paper. Porosities exist in the functionally graded material (FGM) according to even and uneven distributions. Properties of constituent materials are assumed to be temperature dependent and effective properties of the porous FGM are determined using a modified rule of mixture. Governing equations are based on the classical shell theory taking into account geometrical nonlinearity and interactive pressure from surrounding elastic medium. Multi-term analytical solutions are assumed to satisfy simply supported boundary conditions and the Galerkin method is adopted to derive nonlinear load – deflection relations and buckling loads. Parametric studies are carried out to analyze the effects of porosity, shell geometry, degree of tangential edge constraint, elevated temperature and elastic media on the buckling resistance and postbuckling strength of toroidal shell segments under a torsional load. The study reveals that tangential edge restraints have considerably beneficial and detrimental influences on the nonlinear stability of torsion-loaded FGM shells at room and elevated temperatures, respectively. The results also find out that the shear layer and the elastic layer of surrounding medium significantly enhances and alleviates the buckling resistance capacity and severity of the snap-through response of the torsion-loaded porous FGM toroidal shell segment, respectively.

Opis:
Purpose Attributable to the depletion of raw materials and for sustainability purposes in construction works. Therefore, this study looked into the effects of nano blast furnace slag (BFS) on the microstructure, mechanical properties, and durability of mortar. BFS was substituted for cement at various weight percentages of 0, 1, 1.5, 3, 5, and 7%. Design/methodology/approach A suspension of water and Nano blast furnace slag was made using ultrasonic mixers to prepare the samples. The suspension was combined with cement and sand using 1 cement, 0.5 water, and 2.75 sand in the mixture to make cement mortar. The mixture was then shaped, left in the mould for 24 hours, and then allowed to cure for 7, 14, 28, 60, and 91 days. SEM was used to investigate the microstructure before and after cement replacement. The mechanical characteristics were evaluated by testing the compressive strength and the surface hardness. While the durability was assessed using the water absorption ratios. Findings The results revealed that increasing the BFS in the mortar improved mechanical characteristics and durability by up to 3% of BFS. Replacing Nano-blast furnace slag for a portion of the cement is a proposed solution to address the problems of environmental pollution and resource consumption caused by cement production. Research limitations/implications Another sustainable material needs to be used for additional investigation. We may evaluate more properties and use different weight percentages. Practical implications Each year, a significant amount of slag is produced as a result of the iron industry, endangering the environment. There have been numerous initiatives to reduce slag’s negative environmental consequences. Using slag to replace some of the cement is one of the options to eliminate this byproduct and reduce excessive cement use. Originality/value This study investigates the possibility of using a blast furnace blast within the Nanoscale to replace some of the cement used in the construction due to the positive impact on the environment to get rid of industrial byproducts and decrease the use of cement.

Opis:
Honeycomb structures with zero Poisson’s ratio show promising potential for application in variable-sweep wing aircraft. The shear properties of these honeycomb structures serve as a crucial indicator of their morphing capacity. This paper derives the linear and non-linear shear properties of a honeycomb structure with zero Poisson’s ratio. A modified factor is introduced to establish a relationship between the linear and non-linear shear modulus of the honeycomb structure, simplifying the calculation method of the non-linear shear modulus. The validity of theoretical predictions is then confirmed using the finite element method Furthermore, the influences of the geometric parameters on the shear properties of the honeycomb structure with zero Poisson’s ratio are investigated, highlighting the varying contributions of these cell geometric parameters to the shear properties.

In this paper, we obtain some closed form series solutions for the time fractional diffusion-wave equation (TFDWE) with the generalized time-fractional Caputo derivative (GTFCD) associated with a source term in polar coordinates. These solutions are found using generalized Laplace and Hankel transforms. We obtained the closed form series solutions in the form of the Polygamma function. The effect of the fractional order derivative on the diffusion-wave variable is illustrated graphically.

Opis:
Treatment of Municipal wastewater by Electrocoagulation (EC) process using punched aluminium and zinc electrodes was studied in a batch EC cell reactor. Response surface methodology (RSM) based on Central Composite Design (CCD) was utilized to optimize the operating parameters for the removal of % Total Suspended Solids (TSS) and % Chemical Oxygen Demand (COD) from Municipal Sewage. Effect of operating parameters such as Electrode Distance (x1), Electrolysis Time (x2) and Voltage (x3) has been optimized for the removal of TSS and COD. The prediction of removal percentage of TSS and COD in various Operational circumstances is done by using Quadratic model. The significance of each operating parameter was computed by Analysis of variance (ANOVA). To achieve the maximum removal of % TSS and % COD, the optimum conditions were Electrode distance(x1)-3 cm, Electrolysis Time (x2)-70.299 minute and Voltage (x3)-6.5V. It was observed that the performance of electrocoagulation process increased up to 61.45% for COD removal, and 73.73% for TSS removal using punched electrode compared to plane electrodes.

Opis:
The electronic quasi-bound state in the continuum concept is explored in an InGaAs/InAlAs heterostructure to create a voltage-tunable dual-colour quantum Bragg mirror detector. This heterostructure is based on one main quantum well embedded between two different superlattices. By bandgap engineering, each superlattice gives rise to quasi-bound states in the continuum with a preferential direction for electron extraction. Due to these states, the photovoltaic photocurrent presents a dual-colour response, one in a positive direction at 340 meV (3.6 µm), and one in a negative direction at 430 meV (2.9 µm). The simultaneous dual-colour detection can be switched to a single-colour detection (340 meV or 430 meV) by applying a bias voltage. At 77 K, the specific detectivity for simultaneous dual-colour is 2.5·10⁸ Jones, while the single-colour detectivities are 2.6·10⁹ Jones at +2.0 V and 7.7·10⁸ Jones at -1.6 V for 340 meV and 430 meV, respectively.

Opis:
Donkeys are a public health concern in the Northeast region of Brazil, with thousands of stray animals. Orchiectomy is an important population control measure; however, the long postoperative period with daily treatment of open wounds in the scrotum makes it difficult to perform a large number of castrations in sheltering centers. We evaluate a novel surgical procedure for orchiectomy in donkeys using parascrotal access. Twelve donkeys were used, divided into two groups: I - submitted to orchiectomy through parascrotal surgical access (novel procedure), and II - submitted to orchiectomy through scrotal access (conventional). Postoperative evaluations consisted of a macroscopic evaluation of the surgical wound (bleeding and intensity of edema), hematological parameters, and peritoneal fluid, which occurred in both groups at the moments (M): M0 - before the surgical procedure. The others moments occurred after surgery: M12 (twelve hours); M24 (twenty-four hours); M48 (forty-eight hours); M72 (seventy-two hours); M8D (eight days); and M16D (sixteen days). The surgical techniques did not generate an important systemic inflammatory response to the point detected by the leukogram, fibrinogen dosage, and peritoneal fluid. The parascrotal technique required long surgery but promoted less bleeding, less edema, and faster healing. The techniques used did not promote sufficient systemic inflammation to alter the number of leukocytes and the fibrinogen concentration; however, evaluation of the peritoneal fluid proved to be important for evaluating inflammatory processes involving the scrotum and inguinal canal. We describe a novel surgical procedure for orchiectomy in Donkeys using a parascrotal access that promoted less risk of bleeding, shorter period of edema, and healing time, but required longer surgery time.

Opis:
The inflatable liferaft layout applied to passenger ships for the effectiveness of the evacuation process must be based on IMO MSC.1/Circ. 1533 regulations with the maximum evacuation duration is n ≤ 60 minutes. Based on the data from KNKT, in 2021, sea transportation became the biggest contributor to accidents with 342 people dying and missing. Liferaft is one of the main safety tool used during an emergency to save the people and leave the ship. This study used Thunderhead Pathfinder software which was Agent Based Evacuation Simulation combined with 3-D simulation results. The modeling was conducted with two types of layout liferaft and two scenarios of dangerous conditions, the first was a fire in the engine room and the second is the ship experiencing a 20° of heel. The results of this study indicate that there was a difference in the total evacuation duration between the existing layout and the layout that has been changed according to the writer's suggestion. In fire conditions there is a difference of 1 minute 18 seconds in case 1, 1 minute 16 seconds in case 2, 1 minute 38 seconds in case 3, and 22 seconds in case 4. In the heel condition there is a difference of 1 minute 19 seconds in case 1 and 1 minute 25 seconds in case 2. The results of the evacuation simulation modeling with the liferaft layout on the navigation deck that have been modified according to the writer’s suggestion in all cases are getting a value of n ≤ 60 minutes and also have complied with the IMO MSC.1/Circ. 1533 regulations.

Opis:
The process of vitrification of the cumulus-oocyte complex (COCs) often results in cold shock. When warming, heat shock occurs which can disrupt the balance of intracellular calcium (Ca2+) intensity. Drastic changes in temperature cause Reactive Oxygen Species (ROS), affecting changes on Ca2+ in COCs. The role of calcium is needed for oocyte activation in the fertilization process. The purpose of this study was to measure the expression of Ca2+ and the intensity of Ca2+ in COCs after vitrification. The study was divided into 2 groups, the control group (C) of fresh COCs, and the treatment group (T) of COCs after vitrification. After vitrification for 24 hours, then thawing, the expression of Ca2+ was examined using the Immunocytochemistry (ICC) method and the intensity of calcium (Ca2+) with a Confocal Laser Scanning Microscope (CLSM). The research data obtained were analyzed statistically by T-Test. The results showed that the expression of Ca2+ in the control group (12.00±0.00) was different from the treatment group (0.35±0.79). The intensity of Ca2+ in the control group (1059.43±489.59) was different from the treatment group (568.21±84.31). The conclusion of this study is that cryopreservation affects calcium in COCs; there were differences in the expression and the intensity of Ca2+ between fresh COCs and COCs after vitrification. Ca2+ intensity of COCs after vitrification was concentrated in the nucleus, while in fresh COCs it was concentrated in the cytoplasm.
