Self-prescription and self-medication in an urban adolescent population
Authors: Vargas Lucia Micaela , Farias Aníbal Danilo 
Published: June 2024

Background: Self-medication is defined as the use of medicinal products on own account or on the recommendation of other persons outside the medical profession. This practice is quite common, and adolescents are a vulnerable group to the effects that it can cause. Material and methods: A descriptive and retrospective cross-sectional observational study was conducted. The sample included schooled adolescents, of both sexes, between 15 and 18 years who attended 4th, 5th and 6th year of secondary school (EES Nº7, EES Nº1 Manuel Dorrego, EES Nº9 (Normal), EES N19, EESA Nº1 "Florencio Molina Campos") in establishments in the city of Junín, Province of Buenos aires. The data collection tool was a voluntary, anonymous, multiple-choice survey open through a Google form. The data was captured and interpreted in tables and graphs in Excel. Results: This work determined that 72,9 % (84) of the adolescents enrolled in school engage in the practice of self-medication, therefore 20,8 % (22) did not. 86,9 % (73) of the adolescents who self-medicated did so for headache, 56 % (47) for fever, 50 % (42) for sore throat. 86,9 % (73) of the adolescents studied consumed ibuprofen, being the most chosen according to their answers. Second, paracetamol is found at 81 % (68. The 63,1 % (53) responded that they did not know the risk of the drugs they consumed, 23,8 % (20) indicated that they had little knowledge about it, while 13,1 % (11) responded that they did. Conclusion: It can be concluded from the previously presented information that most of the adolescents surveyed do not make a responsible use of drugs and have biases for a correct decision making when addressing their medical problem. From a very early age it can be seen that adolescents have been implementing the practice of them. When practiced with such prematurity, they may incur unknown risks by not knowing the specific uses of medicines and consequently obtain a counterproductive result when using them

Published: June 2024

Background: Coping strategies are changes in thinking and behavior that occur in a person in facing pressure from the environment in the form of stressors. Yogyakarta Special Region is the province with the highest percentage of elderly at 15.52%. Many families choose to entrust the elderly to live in an orphanage. The high level of daily activity carried out by the elderly can increase the physical burden of their caregivers. In this regard, the stressors that arise as a result of caring for the elderly require caregivers to have different coping strategies from each other.Purpose: This research aims to determine the description of stress coping strategies among elderly caregivers at service centersMethods: This research design uses non-experimental descriptive quantitative research methods. The sampling technique used total sampling with a total sample of 34 caregivers. The measuring tool uses The Ways of Coping questionnaireResults: The results show that the majority of caregivers, 55.9%, use Problem Focused Coping (PFC). In coping strategies based on respondent characteristics, the results showed that gender, age, marital status and length of work all used PFC. Then, based on education level, the results showed that high school graduates used Emotional Focused Coping (EFC) and D3/Bachelor graduates used PFC. Furthermore, in terms of characteristics based on religion, the results showed that Muslim caregivers used PFC and Catholic caregivers used both.Conclusions: The majority of categories of stress coping strategies used by elderly caregivers are Problem Focused Coping

Published: June 2024

Background
Plastic pollution is a significant issue on the East Coast of Surabaya, emphasizing the need to develop microplastic monitoring programs. Barnacles became one of the potential microplastic bioindicator species on the East Coast of Surabaya. This study aimed to characterize the visual and polymers of microplastics found in barnacles and assess their potential as a bioindicator species for microplastic pollution on the East Coast of Surabaya.

Methods
Microplastic polymer analysis was performed using ATR-FTIR.

Results
A total of 196 microplastic particles were found in barnacles, water, and sediment. The size of microplastics in barnacles, water, and sediment varied, with the size in barnacles dominated by class 1 (1–10 µm), in water by class 2 (10–50 µm), and in sediments by class 3 (50–100 µm). Fragments dominated the shape of microplastics in barnacles, while water and sediment were dominated by fiber. The microplastic color in barnacles, water, and sediment was dominated by blue, and the microplastic polymer composition on barnacles, water, and sediments was dominated by cellophane (36%). Amphibalanus amphitrite was found to be predominant and identified as a potential microplastic bioindicator because it is a cosmopolitan species. Its population was found to correlate positively with cellophane (CP) accumulation. The Pearson’s correlation test between barnacle length and microplastic length at a = 0.05 was inversely proportional to r = − 0.411 (p < 0.05), categorized as a strong enough correlation. These findings are essential in developing monitoring programs and mitigating the impact of microplastics on the marine environment.
Design with Composites
Authors: Kere Petri 
Published: July 2012

Abstract
Composite materials provide the designer with freedom to tailor mechanical properties and load response of the structure to obtain the maximum efficiency in weight. Anisotropic mechanical behavior of the employed materials and special failure modes make the analytical study and design of a composite structure complicated. In this article, elementary concepts for composite material constituents selection and tools for mechanical design of composite structures using fiber‐reinforced composite materials are introduced. Illustrations of fundamental mechanical properties of composite materials and design guidelines for forming laminated composite structures are outlined.
Viscoelastic Behavior
Authors: Miyano Yasushi 
Published: July 2012

Abstract

Mechanical properties of polymers markedly change with time and temperature, exhibiting what is called
viscoelastic behavior.
Composite materials containing a polymer as their matrix are likewise expected to display viscoelastic behavior. The viscoelasticity of a polymer is explained by the use of a dynamic model, with mention being made of creep and relaxation, both of which are kinds of viscoelastic behavior, and also of the time—temperature superposition principle. Then, on the basis of this explanation, the viscoelasticity of composite materials is described using the simple rule of mixtures. Time and temperature dependence observed in relation to the mechanical behavior and fracture phenomenon of polymer‐based composites is then explained, referring to a specific example of unidirectional carbon‐fiber‐reinforced plastic (CFRP).
Asymmetric membranes by wet phase inversion of phenylated polyphenylene
Authors: Guo Congran , Budy Stephen M. , Loy Douglas A. 
Published: July 2012

AbstractAsymmetric membranes of phenylated polyphenylene were prepared by wet phase inversion. The polyphenylene (Mn = 62 kDa, PD = 2.3) was prepared by Diels–Alder polymerization of 1,4‐bis(tetraphenylcyclopentadienonyl)benzene with 1,4‐diethynylbenzene at 180°C. Solvents and non‐solvents were experimentally identified and solvent : non‐solvent systems were evaluated by the quality of the resulting membranes. Cyclohexanone/n‐butanol (88 : 12) as solvent and n‐butanol as the non‐solvent were found to afford the best asymmetric membranes with minimal defects. Membranes (20–30 µm thick) from coagulating 11.5 wt % polyphenylene from cyclohexanone/n‐butanol in n‐butanol baths exhibited 250–300 nm, non‐porous skins overlaying 20–30 µm of open‐celled, spongiform structure. Due to a relatively high glass transition temperature of 370°C, the phenylated polyphenylene membranes retained their porosity to 200°C higher than polysulfone asymmetric membranes. © 2012 Wiley Periodicals, Inc.

Discrete‐time Adaptive ILC for Non‐parametric Uncertain Nonlinear Systems with Iteration‐Varying Trajectory and Random Initial Condition
Authors: Chi R. H. , Hou Z. S. , Jin S. T. , Wang D. W. 
Published: July 2012

AbstractThis paper presents a new discrete‐time adaptive iterative learning control approach (AILC) for a class of time‐varying nonlinear systems with nonparametric uncertainties and non‐repeatable external disturbances by incorporating a novel iterative estimate scheme. A major distinct feature of the presented approach is that uncertainties can be completely compensated for, using only I/O data. Another distinct feature is that the pointwise convergence is achieved over a finite time interval without requiring the matching condition on initial states and reference trajectory. Rigorous mathematical analysis is developed, and simulation results illustrate the effectiveness of the proposed approach.
Adaptive Decentralized NN Control of Nonlinear Interconnected Time‐Delay Systems with Input Saturation
Authors: Li Tieshan , Wang Dan , Li Junfang , Li Yongming 
Published: July 2012

AbstractIn this paper, a novel decentralized adaptive neural control scheme is proposed for a class of interconnected large‐scale uncertain nonlinear time‐delay systems with input saturation. Radial basis function (RBF) neural networks (NNs) are used to tackle unknown nonlinear functions. Then, the decentralized adaptive NN tracking controller is constructed by combining Lyapunov–Krasovskii functions and the dynamic surface control (DSC) technique, along with the minimal‐learning‐parameters (MLP) algorithm. The stability analysis subject to the effect of input saturation constraints are conducted with the help of an auxiliary design system based on the Lyapunov–Krasovskii method. The proposed controller guarantees uniform ultimate boundedness (UUB) of all of the signals in the closed‐loop large‐scale system, while the tracking errors converge to a small neighborhood around the origin. An advantage of the proposed control scheme lies in the number of adaptive parameters of the whole system being reduced to one and in the solution of the three problems of “computational explosion,” “dimension curse,” and “controller singularity”. Finally, simulation results along with comparisons are presented to demonstrate the advantages, effectiveness, and performance of the proposed scheme.
Examination of the Temperature Variations on the Bray‐Liebhafsky Oscillatory Reaction

Published: July 2012

AbstractThe decomposition of hydrogen peroxide in the presence of potassium iodate and sulphuric acid (the Bray‐Liebhafsky oscillatory reaction) is analysed at different temperatures. It is noted that the temperature variation at constant acidity have the similar effect on the system as the acidity variation at constant temperature. Thus, the character of oscillations can be changed by temperature variation; the system thereby shifts to some other kinetic state in which the resumption of the oscillatory trains, in the region of the smooth catalysis after completion of the last regular oscillation, can be provoked by dilution. In spite of this, the activation energy of the overall reaction is calculated.
SINDO1 study of diffusion in β‐LiAl
Authors: Geudtner Gerald , Köster Andreas M. , Jug Karl 
Published: July 2012

AbstractThe diffusion of lithium‐ and aluminium in lithium‐rich and aluminium‐rich phase regions of β‐LiA1 was studied with the semiempirical MO method SINDO1. A cluster approach was used for the simulation of the bulk. The barrier heights for diffusion were determined without and with relaxation of the adjacent part of the lattice. It could be shown that the diffusion of an Li atom is very likely both in the lithium‐poor and lithium‐rich phase region.

Published: July 2012

AbstractMonoisotopic80SeCF2has been prepared, and high resolution (2.5−3.3×103cm1) Fourier transform infrared spectra in the v3(v0431.053 cm−1) and v4regions (v01208.790 cm1) have been recorded. The hitherto unknown rotational constants that were obtained by means of ground state combination differences assisted the search for microwave transitions ofMSeCF2species, M=76, 77, 78, 80, and 82, in the 5‐26 GHz range and of millimeter wave transitions for M=78 and 80 in the 152‐240 GHz region. Ground state constants up to quartic terms of the five isotopic species were determined by merging all available data. Excited state parameters of the v3=1 and v4=1 states were also determined. It is concluded that these states are unperturbed at the present level of accuracy, which is 4.5×10−4cm1for the rms deviation of more than 6000 (v3) and 12000 IR transitions (v4). Ab initio calculations at the correlated levels of second order Møller‐Plesset pertubation theory using different basis sets were performed. Experimental and theoretical results were combined to deduce effective (r0), average (rzand equilibrium (re) structural parameters. The equilibrium parameters are r(C‐F) 1.309(2) Å, r(CSe) 1.739(2) Å and ∠(FCF) 107.74(4)°.
Quantification of small cyclic disulfide‐rich peptides
Authors: Conibear Anne C. , Daly Norelle L. , Craik David J. 
Published: July 2012

AbstractCyclic disulfide‐rich peptides ranging in size from ∼14 to 29 amino acids have been found in a wide variety of organisms and have exciting biological and medicinal applications due to their stability and structure. Many of these peptides can be chemically synthesized, but their small size and limited number of chromophore‐containing amino acids make them difficult to quantify by methods routinely used for large proteins. A comparison of the precision and accuracy of gravimetric, UV‐ and NMR‐based methods in current use for the quantification of small peptides is presented for a representative set of cyclic disulfide‐rich peptides. The study shows that gravimetric and UV absorbance methods should be used with caution for small peptides and all methods should be carefully validated. For the routine quantification of small disulfide‐rich peptides, we recommend comparison of the analytical reverse‐phase high‐performance liquid chromatography trace or UV absorbance at 214 nm with that of a standard peptide solution quantified by amino acid analysis. An accurate quantification method that is simple and cost effective will assist in comparison of inhibition and activity data between different laboratories and peptides and correct calculation of synthesis yields. © 2012 Wiley Periodicals, Inc.

Host cell protein quantification by fourier transform mid infrared spectroscopy (FT‐MIR)

Published: July 2012

AbstractProcess development in up‐ and downstream processing requires enhanced, non‐time‐consuming, and non‐expensive monitoring techniques to track product purity, for example, the level of endotoxins, viral particles, and host cell proteins (HCPs). Currently, HCP amounts are measured by laborious and expensive HCP‐enzyme‐linked immunosorbent assay (ELISA) assays best suited for measuring HCP amounts in the low concentration regime. The measurement of higher HCP amounts using this method requires dilution steps, adding dilution errors to the measurement. In this work we evaluated the suitability of attenuated total reflection spectroscopy for HCP quantification in process development, using clarified cell culture fluid from monoclonal antibody producing Chinese hamster ovary‐cells after treatment with different polyelectrolytes for semi‐selective clarification. Forty undiluted samples were chosen for multivariate data analysis in the middle infrared range and predicted HCP‐values were in good agreement with results obtained by an ELISA‐assay, suggesting the suitability of this new method for HCP‐quantification. As this method is able to quantify HCP titers ranging from approximately at least 20,000–200,000 ng mL−1, it is suitable especially for monitoring of process development steps with higher HCP concentrations, omitting dilution errors associated with ELISA assays.

A pore‐hindered diffusion and reaction model can help explain the importance of pore size distribution in enzymatic hydrolysis of biomass
Authors: Luterbacher Jeremy S. , Parlange Jean‐Yves , Walker Larry P. 
Published: July 2012

AbstractUntil now, most efforts to improve monosaccharide production from biomass through pretreatment and enzymatic hydrolysis have used empirical optimization rather than employing a rational design process guided by a theory‐based modeling framework. For such an approach to be successful a modeling framework that captures the key mechanisms governing the relationship between pretreatment and enzymatic hydrolysis must be developed. In this study, we propose a pore‐hindered diffusion and kinetic model for enzymatic hydrolysis of biomass. When compared to data available in the literature, this model accurately predicts the well‐known dependence of initial cellulose hydrolysis rates on surface area available to a cellulase‐size molecule. Modeling results suggest that, for particles smaller than 5 × 10−3 cm, a key rate‐limiting step is the exposure of previously unexposed cellulose occurring after cellulose on the surface has hydrolyzed, rather than binding or diffusion. However, for larger particles, according to the model, diffusion plays a more significant role. Therefore, the proposed model can be used to design experiments that produce results that are either affected or unaffected by diffusion. Finally, by using pore size distribution data to predict the biomass fraction that is accessible to degradation, this model can be used to predict cellulose hydrolysis with time using only pore size distribution and initial composition data.

Published: July 2012

AbstractThe antibiotic elansolid C1 (8) was isolated from Chitinophaga sancti strain FxGBF13 after fermentation in the presence of anthranilic acid. Remarkably, 8 was also obtained by addition of anthranilic acid to a crude fermentation extract containing the macrolide elansolid A2 (1*). This Michael‐type conjugate addition allowed us to generate 21 new derivatives of elansolid C1 (9–29) by using various nucleophiles. Biological activities of all derivatives were evaluated against Staphylococcus aureus, Micrococcus luteus, and the mouse cell line L929.
