Published: June 2024

Los ladrillos maletas son ampliamente utilizados en el sector constructivo, debido a la resistencia, capacidad térmica y acústica que poseen; además que en su fabricación está involucrada la subsistencia de muchas familias dedicadas a esta actividad. Sin embargo, el potencial de contaminación en la manufacturación del ladrillo debido a la quema que son expuestas trae consigo múltiples afectaciones que cada día van deteriorando considerablemente el medio ambiente, ante esta problemática se ha desarrollado la presente investigación que trata sobre la fabricación del ladrillo maleta artesanal mediante la aplicación de diversas concentraciones de cemento, para lo cual se efectuó 8 tratamientos con los siguientes porcentajes de cemento (0,10%, 0,25%, 0,5%, 1%, 2%, 4%, 6%, 8% y un testigo), en el cual cada tratamiento consto de 4 ladrillos para luego ser expuestos dos de cada tratamiento al proceso de quemado, para finalmente comparar su resistencia entre los ladrillos que no se sometieron a este proceso en comparación del ladrillo de manufacturación tradicional, mediante una máquina de compresión de cuatro columnas para roturas de probetas de hormigón se realizó la rotura de cada uno de los ladrillos artesanales en estudio. Según los resultados obtenidos los ladrillos del tratamiento con el 4% de cemento del proceso de quemado mostraron el resultado de mayor resistencia de 121,01 Kgf/cm2, también se puede notar que el tratamiento con el 1 % de cemento sin procesos de quemado presento un valor de 28,43 Kgf/cm2 que representa superior a la mitad de la resistencia a la compresión del ladrillo tradicional con proceso de quemado de 46,51 Kgf/cm2 (Testigo).

Introduction Clavicular fractures can be managed surgically or via a non-operative approach. In those electing for surgical fixation, post-operative CXR may be routine practice in the post-anesthesia care unit (PACU) for a rare complication of pneumothorax (PTX), thus driving up the cost for managing these fractures. The value and associated cost of this routine CXR in PACU following open reduction internal fixation (ORIF) of clavicles has not been thoroughly assessed. In this study we investigate the cost effectiveness of obtaining CXR after operative treatment of clavicle fracture. Materials and Methods Study was designed as a healthcare two-way dichotomous model with decision trees built in where a CXR was either obtained or not. Literature review was performed to determine the cost estimates of CXR, the cost of ORIF, and associated hospital stay expenses. Annual volume of clavicle ORIF’s performed were derived from the PearlDiver database, queried for CPT-23515 (Clavicle ORIF). Estimation of CXR rates were performed from 3% to 98% of patients undergoing clavicle ORIF. Net monetary analysis with associated sensitivity analysis of 10,000 repetitions was performed. Results The strategy without CXR proved to be the most cost-effective strategy with a net monetary benefit (NMB) of $32,022.50. At $50,000 willingness to pay (WTP), the no CXR strategy was the preferred option. This strategy was found to be optimal 76% of the time followed by routine CXR 23% of the time and less than 1% being indifferent. The national annual costs of routine CXR after clavicle ORIFs was estimated to range from $7,100 to $349,860, which over 10 years represents anywhere from $81,540 to $2,663,640 in additional expenses. Conclusion The provided study demonstrates that routine CXR after clavicle ORIF is not cost effective. Due to the exceedingly low incidence of PTX as a post-operative complication in clavicle ORIF, we recommend that hospitals and surgeons refrain from ordering radiographs in post-operative patients, with the exception of those displaying concerning clinical signs for PTX or those with known pre-operative pulmonary injury. Adopting this strategy will limit unnecessary healthcare costs accrued by patients and may be the more clinically appropriate management.

Published: June 2024

Background: SCFH accounts for sixty percent of all fractures around elbow. Type III SCFH is unstable. CRPP is treatment of choice. Both the crossed-k wires and lateral-entry k wires have been used successfully; however, superiority has not been established. This study compares stability, functional outcomes, radiological outcomes and complications of these two methods.
Methods: This is a hospital based prospective comparative study undertaken at GMCTH from June 2019 to November 2020. Fifty-six children of three to thirteen years with extension type III SCFH were included after taking informed consent. Ethical clearance was taken from NHRC, Kathmandu. Patients were followed up for three months. Statistical analysis was done using SPSS 25 and p value <0.05 was considered significant.
Results: The average age of participants was 7.70 years. There were 15 girls (26.7%) and 41 boys (73.3%). Right sided injuries occurred in 32.1% of children with 78.6% sustaining injury on the non-dominant side. Mean duration of fracture healing was 4.75 weeks. Average Baumann’s angle at three completed months in lateral-entry group was 75.04 degrees and crossed-K wires was 74.50 degrees (p=0.374). The average carrying angle in lateral-entry group was 7.79 and crossed-K wires was 7.29 degrees (p=0.303). Average loss of flexion in lateral-entry group was 2.71 degrees and 2.25 degrees in crossed-K wires (p=0.479). Average loss of extension in lateral-entry group was 3.39 degrees and crossed-K wires was 2.82 degrees (p=0.37). Skaggs et al Criteria for grading loss of reduction showed no loss of reduction in all fifty-six cases.Conclusion: Both the lateral and cross pinning techniques are equally efficient in maintaining reduction in management of supracondylar fracture of humerus. The ulnar nerve injury can be avoided while using the medial K wire by pinning in a semi-flexed elbow with ulnar nerve rolled back.

Authors: Adhikari Shila 
Published: June 2024

Background: Lack of respectful maternity care act as more powerful deterrents to skilled birth care utilization than other more commonly recognized deterrents such as geographic and financial obstacles. Ensuring high level of respectful maternity care encourage the women to utilize facility-based care, which is essential for improving maternal and neonatal health. Thus, the objective of the study is to find out autonomy and respect during maternity care among the postnatal mothers in a tertiary level hospital.
Methods: A descriptive cross-sectional study was conducted among 214 postnatal mothers receiving child birth services from the facility were selected by using non-probability purposive sampling technique. Analysis of data was done by using descriptive statistics (number, percentage, mean, standard deviation) and chi- square test was used for association between autonomy and respect and selected socio-demographic variables.
Results: The study result indicated that (74.8%) of the respondents had high level of autonomy. Similarly, (71%) of the respondents reported that they experience high level of respect. A significant association was present between autonomy of postnatal mothers with caste (p=.027) and parity (p=.005) and a significant association was present between respect of postnatal mothers with type of delivery is with p value (.001).
Conclusions: Hence, level of autonomy and respect tends to be high among postnatal mothers during maternity care and is associated with caste, parity and type of delivery. Continuous professional development programme for all cadres of health personnel should be conducted in respectful maternity care of maternity ward.

ABSTRACT
Economic growth is the development of economic activity characterized by an increase in the level of production of goods and services needed by the public. The financial industry is one area that has the power to influence economic expansion. The financial industry has been a major factor in the country's economic expansion. Both conventional and Islamic banks, these two systems can work together side by side To commemorate this, Bank Muamalat Indonesia was established. The purpose of this study is to ascertain how Islamic banking and finance affects economic growth. Multiple linear regression is the data analysis technique used in this study. Several dependent variables and one independent variable were used in this data analysis technique. According to the research findings, Islamic finance is a financial rule or way of working that is based on Islamic legal values. An example of the best feature of Islamic finance in Islamic banking is that it helps distribute capital between the short-term money market and the real sector, which enhances economic growth in Indonesia. To encourage a growing economy, a model to complement the Islamic finance system in the banking industry needs to be introduced. This is an innovation in Islamic banking, a product that represents strategic issues.

Carbohydrate antigen 19-9 (CA 19-9) is the sole FDA-approved serum biomarker for early detection, progression, and treatment response of pancreatic ductal adenocarcinoma (PDAC, pancreatic cancer). It is more specific than other serum biomarkers for PDAC. Understanding the clinical relevance of genetic variants and other conditions on CA 19-9 expression is thus critical for proper interpretation. This review covers PDAC risk assessment, screening, early diagnosis and treatment monitoring with a focus on CA 19-9 and genetic factors that influence serum levels with or without PDAC.
Moral Implication of Big Brother Naija (BBN) on Nigeria Youths
Authors: Jibrin Amos Ochimana 
Published: June 2024

The phenomenon of Big Brother Nigeria (BBN) has garnered significant attention due to its moral implications on Nigerian youth. This paper delves into the ethical ramifications of BBN on the younger generation of Nigeria, exploring how the show’s content influences their behavior, values, and perceptions and other factors that are responsible for moral decline among Nigerian Youths. The rise of reality television programs, such as BBN, has perpetuated a culture of voyeurism and sensationalism, which raises concerns regarding the impact on the moral fabric of Nigerian society. BBN exhibits a wide range of behaviors, including deceit, manipulation, and public humiliation, which can normalize and desensitize the youth to these negative actions. One of the primary moral implications of BBN on Nigerian youth is the erosion of traditional values and ethics. This study adopts historical, descriptive and sociological approaches. It was revealed that the show often emphasizes materialism, instant gratification, and superficiality, promoting a value system that prioritizes fame, wealth, and self-interest. On the positive side, BBN also exposes the Nigerian youth to diverse cultures, backgrounds, and perspectives. It offers a platform for social issues to be discussed, raising awareness and encouraging critical thinking. It concludes that, its content and presentation have the potential to shape the behavior, values, and perceptions of the younger generation. The study recommends that the citizens and government should rise to take serious measure against the activities of Big Brother Naija or better still to set laws that will check and regulate their activities.

AbstractObjectiveTo investigate the effect of a 12‐session walking skill training program of weight‐bearing activities on physical functioning and self‐efficacy initiated in patients 3 months after total hip arthroplasty (THA).MethodsSixty‐eight patients with THA, 35 women and 33 men, with a mean age of 66 years (95% confidence interval [95% CI] 64, 67 years), were randomized to a training group (n = 35) or a control group without physiotherapy (n = 33). Assessments were performed before the intervention at 3 months (pretest), at 5 months (posttest 1), and at 12 months (posttest 2) after surgery. The primary outcome was the 6‐minute walk test (6MWT). The secondary outcomes were the stair climbing test (ST); figure‐of‐eight test; Index of Muscle Function (IMF); active hip range of motion (ROM) in flexion, extension, and abduction; Harris Hip Score (HHS); self‐efficacy; and Hip Dysfunction and Osteoarthritis Outcome Score.ResultsThe training group had larger improvements than the control group at posttest 1 on the 6MWT with an adjusted mean difference of 52 meters (95% CI 29, 74 meters; P < 0.001) and on the ST of −1 second (95% CI −2, 0 seconds; P = 0.01).There were also improvements on the figure‐of‐eight test (P = 0.02), IMF (P = 0.001), active hip ROM in extension (P = 0.02), HHS (P = 0.05), and self‐efficacy (P = 0.04). The difference between the groups persisted at posttest 2 on the 6MWT of 52 meters (95% CI 24, 80 meters; P < 0.001) and on the ST of −1 second (95% CI −3, 0 seconds; P = 0.05).ConclusionThe walking skill training program was effective, especially in improving walking both immediately after the intervention and 1 year after THA surgery.

Published: December 2011

AbstractBlue light‐emitting oligotriphenylene nanofibers are synthesized by oxidizing triphenylene using ferric chloride. By adjusting the monomer concentration, the acid used, and the temperature employed, the average diameter and length of the nanofibers can be readily tuned from 50 to 200 nm and 0.5 to 5 μm, respectively. Structural characterization, electrical conductivity, thermal stability, and fluorescence of oligotriphenylene, along with a proposed nanofiber formation mechanism, are presented. Both oligotriphenylene nanofiber dispersions and oligotriphenylene/polysulfone composite films are developed as fluorescent sensors for detecting traces of nitro‐based explosives including nitromethane, nitrobenzene, and 2,4,6‐trinitrophenol, as well as an electron‐deficient metal ion, Fe(III). The sensors exhibit much better selectivity and sensitivity compared to conventional sensors, with detection limits down to 1.0 nm with a detection range covering ∼4 orders of magnitude. The detection mechanism of the fluorescent sensors is also disscussed.

Published: December 2011

AbstractBackground:Intranasal agents play a critical role in the management of sinonasal disorders. There are ongoing efforts to develop new intranasal medications to combat sinonasal disease. Some intranasal agents, however, can have cytotoxic effects on human sinonasal tissue. In order to facilitate safe drug discovery, we developed a simple and reliable in vitro screening assay using human sinonasal explants to measure the cytotoxic profiles of intranasal agents.Methods:We obtained sinonasal tissues from several regions of the nasal cavity from 12 patients undergoing endoscopic sinonasal surgery. These tissues were cultured on polytetrafluoroethylene membrane in serum‐free growth medium. We determined the biochemical properties of these explants by measuring extracellular lactate dehydrogenase (LDH) levels and performing histological analyses over a period of 1 to 2 weeks. We then examined the cytotoxic profiles of 13 intranasal agents by measuring extracellular LDH levels using the human sinonasal explant system.Results:Sinonasal explants exhibited a rapid reduction in extracellular LDH levels indicating stabilization in the culture environment within 2 days. Histological analysis showed maintenance of good cellular architecture for up to 2 weeks. The explants displayed intact epithelium and expressed βIII‐tubulin and Ki‐67. Of the 13 tested intranasal agents, 1% zinc sulfate (ZnSO4), 5% ZnSO4, and Zicam application were cytotoxic.Conclusion:Based on the unique biochemical properties of the human nasal explant culture system, we developed a simple and reliable in vitro screening assay to determine the cytotoxic profiles of various intranasal agents by examining extracellular LDH levels and histopathology. © 2011 ARS‐AAOA, LLC.

Published: December 2011

AbstractCarbon black (CB) aqueous dispersion was prepared and used to dye the cationic‐modified cotton fabrics through exhaust dyeing process. The effects of CB concentration, CB nanoparticles size, dyeing bath pH, dyeing time and dyeing temperature were investigated. The color yields of dyed fabrics were evaluated on Kubelka‐Munk value K/S. The surface morphologies of cationic modified and nonmodified cotton fabrics were measured by video microscope. The fabrics presented 18.9 of the color yield with the dyeing conditions: the dyeing solution contained 2% o.w.f. CB and dyeing at 80°C for 30 min with pH 13 using a 50 : 1 liquor ratio. The images of the video microscope demonstrated a clear surface profile for the cationic‐modified cotton fabrics dyed with smaller CB particle size solutions. These results indicated that CB nanoparticles were suitable for dyeing the cotton fabrics. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Oxidation and crosslinking processes during thermal aging of low‐density polyethylene films
Authors: Chabira Salem F. , Sebaa Mohamed , G'sell Christian 
Published: December 2011

AbstractThis work analyzes the influence of thermal degradation on the microstructure and the mechanical properties of low‐density polyethylene subjected to aging at 70°C in the dark for times up to 21 months. It is found that the polymer shows a gradual increase of its elastic modulus and a dramatic reduction of its ductility, due to secondary crystallization. Infrared spectroscopy (FTIR) reveals the autoaccelerated oxidation of the polymer after 5 months aging. It is observed that the unsaturated vinylidene groups initially present in the material are gradually overridden by vinyl groups and, eventually, by t‐vinylene groups. Nuclear magnetic resonance (13C NMR) shows that the initial butyl chain branches are progressively completed by shorter ramifications, namely ethyl branches. These results are discussed in term of macromolecular mechanisms: (i) oxidation, (ii) chain scission, and (iii) crosslinking. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Generalized magneto‐thermoelastic medium with variable material properties subjected to ramp‐type heating
Authors: Youssef Hamdy M. , El‐Bary A. A. 
Published: December 2011

AbstractThe equations of magneto‐generalized thermoelasticity with one relaxation time with variable electrical and thermal conductivity for one‐dimensional problems are cast into a matrix form using the state–space approach and Laplace transform techniques. The resulting formulation is applied to a problem of a half space where the bounded plane is subjected to a ramp‐type heating and a traction free. This takes place when a constant magnetic field permeates the medium in the absence of an external electric field. The inversion of the Laplace transform is carried out using a numerical approach. Numerical results for the temperature, the displacement, and the stress distributions are given and illustrated graphically. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Effect of the electron beam irradiation on the properties of epoxidized natural rubber (ENR 50) compatibilized linear low‐density polyethylene/soya powder blends
Authors: Sam S. T. , Ismail H. , Ahmad Z. , Ratnam C. T. 
Published: December 2011

AbstractLinear low‐density polyethylene/soya powder blends were prepared by using an internal mixer at 150°C. The soya powder content ranged from 5 to 40 wt %. Epoxidized natural rubber with 50 mol % epoxidation (ENR 50) was added as a compatibilizer. The blends were irradiated by electron beam (EB) at a constant dose of 30 kGy. The changes in gel fraction, tensile properties, morphological and thermal properties of the samples were investigated. The gel content increased after EB irradiation. However, the increment of gel content was hindered by increasing soya powder content. The tensile strength and Young's modulus of the blends were increased by EB whereas the elongation at break decreased. The tensile fracture surface also support the reduction of elongation at break by EB irradiation. Further analysis on the irradiated blends using Fourier transform infrared spectra indicated an increase of oxygenated product after undergoing EB irradiation. The differential scanning calorimetry result indicated that the melting temperature of the blends decreased after EB irradiation whereas the crystallinity increased. EB irradiation also enhanced the thermal stability of the blends as indicated by thermogravimetric analysis. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
