Whey represents an important environmental problem for the dairy industry due to its high volume and organic load. Studies that evaluate new forms of use of these residues such as growth medium for microorganisms, can help to develop a better destination providing an added value bioproduct. This work aims to evaluate the development of Bacillus atrophaeus spores ATCC 9372 growing in whey culture media to determine the reuse of this dairy residue. Whey at a concentration varying from 1.0g. L-1 to 20.0g. L-1 was dissolved into water and Bacillus atrophaeus spores were incubated for 6 days. Thermal treatments were performed at 102oC and 104oC and in all conditions evaluated, the decay of spores population was linear. In solid media, D-values at 102oC ranged from 1.24 min to 2.98 min and at 104oC ranged from 1.27 min to 2.35 min. The culture media containing whey can enable the growth and sporulation of Bacillus atrophaeus.

Published: December 2022

Mucormycosis is an angioinvasive, fatal infection commonly seen in individuals with diabetes mellitus, malignancy and immunosuppression due to chemotherapy and steroids. The aim of this study was to identify the association between adverse clinical outcomes and patient co-morbidities in mucormycosis. Over a period of 14 years, clinical specimens positive for mucormycosis by fungal culture and histopathological examination were included in the study. Statistical analysis was performed to identify the association between adverse clinical outcome and patient demographics. Odds ratio with a 95% confidence interval was calculated to analyse the association between age, gender, diabetes mellitus, malignancy and adverse clinical outcome. p-value <0.05 was used to identify statistical significance. 63 patients with mucormycosis were identified in the study. Rhino-orbital-cerebral mucormycosis was seen in 70% of patients and Rhizopus (52.7%) was the most commonly isolated fungus. Antifungal therapy (92.06%) and surgery (68.25%) were the treatment modalities utilised with a mortality rate of 26.9%. No significant statistical correlation was found between age, gender, presence of diabetes mellitus, malignancy and adverse clinical outcome. Rhino-orbital cerebral mucormycosis due to Rhizopus spp was the most common clinical presentation seen in our setting. Combination of antifungal therapy and surgery is vital for clinical response. Diabetes mellitus and malignancy do not show a statistically significant association with the clinical outcome of mucormycosis. Rapid identification of mucormycosis helps in early diagnosis and initiation of antifungal therapy.

Published: December 2022

The present study intends to provide information about a promising source of unique bioactive compounds and for choosing the favorable growth conditions of the diatom “Phaeodactylum tricornutum” suited to different applications. P. tricornutum was cultivated in the temperature range of 20-35°C, light intensity range of 275-538 μmolm-2s-1 and aeration rate range of 2.5- 3.5 Lmin-1. P. tricornutum extracts were analyzed in terms of photosynthetic pigment composition in comparison with a well-known green microalgae Chlorella miniata using the C18 column. Lutein, canthaxanthin, β-carotene and chlorophyll a were detected in C. miniata whereas in P. tricornutum extracts, chlorophyll a, zeaxanthin and β-carotene were identified. Quantitatively, P. tricornutum was distinguished to have greater amount of chlorophyll-a (113.66 mgmL-1) while C. miniata was predominated with a β-carotene content (14.20 mgmL-1). Considerable amounts of pigments were encountered in all of the P. tricornutum extracts obtained under the varying growth conditions. As the temperature was increased and the light intensity was decreased, the accumulation of chlorophyll a and β-carotene increased at the highest aeration rate. Conversely, at the highest light intensity of 538 μmolm-2s-1 and an aeration rate of 3.0 to 3.5 Lmin-1, the zeaxanthin content was maximized and limited at the temperature values over 27.5°C.

EMPLOYING THE BIM-BASED APPROACH TO ANALYZE AND IMPROVE THE QUALITY OF DETAIL CONSTRUCTION COST ESTIMATION ACCORDING TO NRM 2 AND SMPI
Authors: Emelia Purba Sarah , Diandra Nadia , Feng Chung-Wei
Published: December 2022

Construction projects have become increasingly complicated and challenging to manage in recent years, especially in analyzing the quantity and cost estimation of construction work to get accurate results and overrun costs. The interdependence among different work items involved, such as architects, civil and electrical works, is one of the fundamental reasons. Besides that, the differences in standards used in analyzing the quantity and unit cost per work item made it more complicated. This study analyzed the existing modeling based on the measurement rules and unit cost standards to analyze the problem which has been explained above. Understanding the items was considered when examining the walls quantity to avoid missing information. In addition, measurement rules standards are utilized to calculate QTO, including NRM 2 standards from the UK and SMPI standards from Indonesia, to calculate the cost based on Indonesia standard SNI-AHSP. Furthermore, using visual programming Dynamo to analyze the quantity of wall works based on the required data, extract the data/information needed to calculate the cost based on unit cost standard, and check if the walls intersect with other elements to avoid excess quantity. Finally, using BIM technology based on standard measurement rules and overlapping element analysis to calculate the quantity and cost produced accurate quantity results and obtained the maximum cost detail per work item. Moreover, generate the information about the analysis results by utilizing the intelligent module to present the required information of the wall works, which improves the inadequacy of BIM. Indeed, it could save more time than calculating them manually and reduce human errors.

Authors: Do Jean-Louis , Auvray Thomas , Lennox Cameron , Titi Hatem , Cuccia Louis , Friscic Tomislav
Published: December 2022

Gold is highly valued for its wide-ranging commercial and technological use and is currently almost exclusively processed via aggressive reaction conditions that produce water soluble salts. Oxidative mechanochemistry has previously been shown as a rapid, mild, and room-temperature alternative for chemically activating and transforming gold into water soluble species in the presence of potassium and ammonium halides. Demonstrated here is the extension of this strategy in the presence of tetraalkylammonium halides to directly and efficiently produce salts soluble in pure organic solvents and aqueous alcoholic media. This method affords gold salts that are rapidly and easily purified from byproducts using benign and easily recycled solvents and can be readily used for subsequent materials synthesis such as Au(I) salts and gold nanoparticles.
Sedimentation of colloidal nanoparticles in fluids: efficient and robust numerical evaluation of analytic solutions of the Mason-Weaver equation
Authors: Barthe Lancelot , Werts Martinus H. V.
Published: December 2022

The Mason-Weaver equation (MWE) is an advection-diffusion equation that describes the time-evolution of the concentration profile of a solution of nanoparticles undergoing sedimentation and Brownian motion from an initially homogeneous state towards sedimentation equilibrium. In spite of the availability of analytic solutions, recent work has used numerical schemes to obtain practical solutions for the MWE. Here, the numerical evaluation of analytic solutions of the MWE is investigated using standard floating-point computations. It was found that the numerical evaluation is not always straightforward as this involves summing over an infinite series of terms which is sometimes automatically truncated due to limitations in floating-point computation. By combining several analytic expressions, each having its own range of validity in the MWE parameter space, robust and computationally efficient numerical evaluation of the solution is finally achieved. The expressions and the numerical procedure have been coded into a computer program enabling practical calculation of nanoparticle sedimentation profiles.

Published: December 2022

Alkaline anion exchange membranes (AAEMs) are an enabling component for next generation electrochemical applications, including alkaline fuel cells, alkaline water electrolyzers, CO2 electrochemical reduction, and flow batteries. While commercial systems, notably fuel cells, have traditionally relied on proton-exchange membranes (PEMs), hydroxide-ion conducting AAEMs hold promise as a way to reduce cost-per-device by enabling the use of less expensive non-platinum group electrodes and cheaper cell components. AAEMs have undergone significant material development over the past two decades resulting in substantial improvements in hydroxide conductivity, alkaline stability, and dimensional stability. Despite these advances, challenges still remain in the areas of durability, water management, high temperature performance, and selectivity. In this review we discuss crosslinking as a synthesis tool for tuning various AAEM material properties, such as water uptake, conductivity, alkaline stability, and selectivity, and we describe synthetic strategies for incorporating crosslinks during membrane fabrication.

Hare (una técnica fotográfica)
Authors: Ballón Aguirre Enrique
Published: December 2022

De las mil y un pregunta que pueden dirigirse a las condiciones de producción de ese fenómeno o "dato" llamado fotografía, la semiótica plenaria elige sólo esta: ¿cómo significa y qué significa una fotografía?Hecha la pregunta, intentar responderla ha supuesto plantear previamente un nuevo objeto de conocimiento que, en primer lugar, reubicara la problematica general de la significación fotográfica desplazándola hacia un punto de vista inédito: el de la intencionalidad y la motivación del enunciador que la produce al poner en relación las cualidades sensibles de un significante visual particular, el fotograma (nivel de expresión de la fotografía) y ciertas cualidades inteligibles o de significado que permiten apercibirlo.
La imprenta libre es el freno de los ambiciosos
Authors: Sánchez Carrión José Faustino
Published: December 2022

Excluimos enteramente las religiones, siguiendo el ejemplo de las Cortes de Cádiz en lo que a nuestro entender dieron una de las pruebas de su sabiduría. Dígase que somos intolerantes: esto poco importa. No queremos se renueven en nuestra Patria las horribles escenas de la Francia. No hay un solo pensador que no inculque sobre la necesidad de este principio, y sobre qué debe ser reconocido por ley constitucional. La imprenta libre es el freno de los ambiciosos.

Auge y caída de la personal(de)idad
Authors: Hevia-Garrido-Lecca Julio
Published: December 2022

La interioridad individual, entonces, opuesta y/ o comple­mentaria a una especie de medioambientalidad social, parece involucionar o verse trastocada por flujos comunitarios aloja­ dos en el mismo sujeto, tornándolo así más permeable a lo externo. Gradualmente asistimos a un descentramiento del ser, a una deportación del yo, a un exilio de la personalidad. Tal deslizamiento no debería extrañarnos pues parece constituir el movimiento inverso -o si se quiere, 'el retorno de lo reprimido'­ de la sucesión dada en el uso del vocablo 'persona'. Sabemos que una lectura estoica, originaria, agotaba tal significante en roles y escenificaciones, mientras que la visión cristiana, al enfatizar el aspecto de la sustancia, terminó centrada en las relaciones: temática amplia y clásicamente ilustrada en la triangulación Padre/Hijo/Espíritu Santo. El concepto más­ cara  -prosopon-  rebalsado  inicialmente  por  el  de  soporte -hypostasis-, contrataca hoy con toda la fuerza de la que es capaz.
El escándalo como forma de dominación política
Authors: Arias Luis Miguel
Published: December 2022

El texto no pretende aportar soluciones a un problema harto conocido al interior del gremio de los politólogos y juristas. Tal fenómeno está en la actualidad generando, en diversos grados, una extensa producción intelectual y una reflexión critica, que pretende arrojar un poco de luz sobre el modo y la forma de funcionamiento de los sistemas políticos en esta época de disolución del antiguo sistema de ordenación internacional, tras la caída del muro y la descomposición del antiguo Bloque del Este. El acento recae especialmente en los sistemas políticos democráticos en la órbita del mundo occi­dental donde la emergencia de ciertos procesos 'perversos' parecerían presagiar el hecho de una profunda crisis de los sistemas representativos . De ello dan cuenta las noticias e informes que aparecen en la prensa y en el resto de los medios, referidos a una serie de escándalos públicos.
