Authors: Wairimu Nancy , Elkana Owaga Eddy , Koskei Kipkorir
Published: May 2022

Baobab is a dry land product rich in vitamins and minerals but has remained underutilized. Therefore, value addition of the baobab pulp through incorporation of pulp to the probiotic yoghurt will promote dietary utilization. Different treatments were made by incorporating different amounts of ground baobab pulp. Treatments were analyzed for protein, fat, ash and moisture content. Total solids, synerisis, titratable acidity, pH, butterfat and specific density, sensory evaluation and shelf life were analyzed. There were significant differences between the treatments in most of the parameters studied. The treatment with the highest amount of baobab pulp showed an increase in levels of total solids, titratable acidity and synerisis but decreased the viscosity of the yoghurt. There were significant variations in sensory attributes and samples with the highest baobab pulp scored the highest for taste, texture, aroma, color and overall acceptability. Incorporating baobab pulp to yoghurt improved its nutritional and physicochemical properties.

Published: May 2022

The input from managers and employees is vital for strategic decision-making. Yet, these people already have enough on their plates if not overwhelmed by their daily to-do lists. We measured how employees in an organizational transformation could save time by stopping to work on non-priorities and stopping to reinvent the wheel by sharing knowledge. First, we designed a new survey scale replacing a Likert survey to ask people for input objectively, reducing interpretation bias. Next, we analyzed survey input from over 32,000 respondents in more than 900 teams in 150 different organization transformations. To free up time, we compared were respondents' planned improvement deviated from their management priorities. To work smarter, we focused on knowledge sharing: how could one employee that already had improved on a specific topic help a colleague that still had to improve? On average, we found a productivity increase of 75 hours, or €2,500.- per respondent. This productivity increase of 75 hours required two things: an average time investment per respondent of max. 15 minutes to answer a questionnaire and an algorithm to indicate 1.) what priorities to focus on and 2.) which colleagues could help with each of these.
Balanço dos dez anos da política federal de cotas na educação superior (Lei nº 12.711/2012)
Authors: Souza Senkevics Adriano , Mattioli Mello Ursula
Published: May 2022

Em 2022, a política federal de cotas (Lei nº 12.711, de 29 de agosto de 2012) completa dez anos desde sua promulgação. O seu artigo 7º prevê que a conclusão do primeiro decênio de vigência deve vir acompanhado de uma revisão dos avanços e obstáculos da reserva de vagas para acesso à graduação nas instituições federais de educação superior. Com o intuito de subsidiar esse debate, neste texto realizamos um balanço dos avanços, limites e desafios da política de cotas. Revisamos a literatura recente e apresentamos resultados de pesquisas próprias para pensar o futuro da Lei de Cotas por meio de quatro pilares: a reserva de vagas para egressos da rede pública; para estudantes de baixa renda; para pretos, pardos e indígenas; e a implementação via Sistema de Seleção Unificada (Sisu). Concluímos que a política se mostrou satisfatória em seus resultados e promoveu grande inclusão no acesso ao ensino superior público. Porém, alguns pontos sensíveis merecem atenção dos legisladores, de gestores públicos e da sociedade, visando ao aprimoramento do sistema de reserva de vagas.

Different dietary ratios of arginine, methionine and lysine for turkeys: effects on whole-body composition and nutrient utilization efficiency in the early growth stage
Authors: Mikulski Dariusz , Ognik Katarzyna , Mikulska Marzena , Jankowski Jan
Published: May 2022

The growth rate, tissue development and health status of turkeys are affected by the dietary supply of essential amino acids (AAs) such as lysine (Lys), methionine (Met) and arginine (Arg). According to various guidelines, the diets fed to turkeys in the first 4 weeks of the rearing period should contain 1.60–1.76% Lys, 1.60–1.80% Arg and 0.55–0.70% Met. This study investigated the effects of different ratios of Arg and Met in starter diets with 1.60% of Lys content, i.e. a low level, on the whole-body composition of turkeys and nutrient retention efficiency. The experiment lasted for 28 days and it had a two-factorial randomized design with three levels of Arg (90%, 100% and 110%) and two levels of Met (30% or 45%), relative to the content of dietary Lys, with six groups of eight replicates per group and 18 turkeys per replicate. Different dietary Arg and Met levels, relative to Lys, did not affect AA concentrations in the body protein or the proximate whole-body composition (crude protein, crude fat, gross energy and ash) of turkeys. The higher Met level positively influenced energy, protein and Arg utilization and their retention efficiency as well as the growth performance of turkeys. An increase in the dietary level of Arg to 100% and 110% of Lys content had no influence on the growth performance of turkeys and it reduced the retention efficiency of Arg. Differences in the body weight gain, feed intake and Lys utilization of turkeys fed diets with different Arg levels resulted also from the strong interaction between Met and Arg levels. At the lower level of Met in the diet, a decrease in Arg relative to Lys from 100% to 90% resulted in decreased (P = 0.003) feed intake (from 50.34 g to 46.72 g) and growth rate (from 31.84 g to 29.79 g), which was not noted for the higher Met content (45% relative to Lys). At the lowest level of Arg in the diet (90% of Lys content), a decrease in Met relative to Lys from 45% to 30% caused a decrease in Lys retention efficiency (from 61.51% to 56.29%). The results of this study suggest that the higher content of Met in the diet (45% to Lys) and the Arg level corresponding to 90% of Lys content contribute to optimizing nutrient retention efficiency in turkeys during the first 28 days of their life.

Published: May 2022

Bacillus subtilis, an isolate of bacillus genus, was obtained from the laboratories of Ministry of Science and Technology. The best efficient Bacillus subtilis isolate in cellulose and semi-cellulose hydrolysis was treated with Dielectric-barrier Discharge (DBD). Atmospheric cold plasma technique (non-thermal) was used by exposing them at different times (2, 3, 4 and 5 mins) separately as a first stage, and then 60 seconds after any treatment separately as a second stage. After 48 hours, the difference between the plasma source and the sample was fixed at 0.5 cm. The results showed a variation in the growth of the isolate according to the exposure time by the appearance of culture turbidity and the estimation of optical density. Positive results appeared between exposure times, the amount of optical density, and the cellulose and semi-cellulose decomposition into glucose. Bacillus subtilis increased its efficacy in cellulosic hydrolysis and semi-cellulosic materials. Bacillus subtilis showed malleability and the ability to increase the efficiency in cellulose and semi-cellulose materials hydrolysis. We conducted a new and extensive study by using cold plasma technique to increase the hydrolysis efficacy of food microorganisms.

Authors: Anggoro Dimas Aryo , Nurfadilah Inayah
Published: May 2022

The Indonesian language is used as a means of communication, including written communication. Unfortunately, many mistakes are found in Indonesian language writing, such as the writing of active verbs with the prefix mem- followed by the letter P. This problem can be addressed with the spell-checking method. Spell checking is a process in computer programs to check the spelling of each word in electronic text or documents in the correct order.  To better the active verb this study used  the Jaro-Winkler Distance algorithm. Meanwhile, for system development, the Iterative Waterfall method was used. The system output is active verbs of mem- + P which is standardized according to the Great Dictionary of the Indonesian Language of the Language Center (KBBI) and the morphological rules of the Indonesian Language Spelling System. The accuracy value of the algorithm was 80% for common mistakes, 95% for specific mistakes, and 80% for correctable mistakes with word suggestions.
Enseñanzas de los Talleres De Creatividad de Antonio Caro
Authors: Solórzano Augusto
Published: May 2022

Este artículo explora el aporte educativo de los Talleres de creatividad visual que Antonio Caro (1950-2021) impartió en el país y en el exterior durante más de treinta años. A través de un novedoso programa pedagógico que recoge ideal de John Dewey de integrar de manera natural el arte y la vida, el artista logra democratizar el arte y potenciar las capacidades creativas consolidando nuevas posibilidades para la experiencia estética-educativa, la inclusión y el desarrollo de competencias de tipo social a través del diálogo y la participación activa.  El objetivo es mostrar que esta práctica artística contemporánea incardina asuntos éticos y estéticos que permiten acercar la teoría educativa a la experiencia del arte en función de sus efectos y potencial pragmático. La metodología fue de tipo cualitativo y se circunscribe a una revisión documental exploratoria de fuentes impresas, electrónicas y audiovisuales. Los resultados permiten concluir que el contenido pedagógico de los talleres, al rehacerse y revisarse permanentemente, construye su propio método de investigación, abre rutas alternas a los modelos educativos del arte institucional, potencia la comunicabilidad y despliega tácticas que dan sentido y dirección a la vida permitiendo que el arte y la educación rehabiliten la dimensión de la experiencia que la razón moderna no pudo abarcar.
Wittgenstein sobre el concepto de lenguaje. Algunas objeciones
Authors: Ruíz Fernández José
Published: May 2022

El artículo hace algunas objeciones a la analogía que Wittgenstein plantea entre los conceptos de lenguaje y juego, según la cual, como no hay algo esencial a las actividades que llamamos juegos, no habría algo característico en las conductas que llamamos lingüísticas. El peligro y confusión de esta analogía, que ya apuntó Rush Rhees, se ponen de relieve aquí de manera diferente, mediante una consideración del carácter de ciertos conceptos psicológicos, incluido el concepto de decir algo.
Cappelen, H. (2012). Philosophy without Intuitions. Oxford University Press
Authors: Franco Ramírez Joel Alejandro
Published: May 2022

Una de las controversias en los debates metafilosóficos contemporáneos gira en torno al presunto uso de intuiciones como evidencia en la filosofía analítica. El problema es que, si los filósofos realmente usan intuiciones, no queda claro qué se entiende por éstas, cómo pueden tener un papel evidencial, o si son siquiera fiables. En su libro Philosophy Without Intuitions, Herman Cappelen se propone abordar esta cuestión que concierne a los fundamentos mismos de la filosofía analítica, dando una respuesta negativa a la pregunta de si los filósofos dependen de intuiciones. Su estrategia consiste en articular dos argumentos que, de acuerdo con él, suelen ser mencionados en apoyo de la existencia del uso de intuiciones en filosofía, para después mostrar que ninguno cumple su cometido. Por lo tanto, sería falso que se utilizan intuiciones como evidencia en filosofía. La obra se divide en dos partes: en la primera (caps. 2-5) desarrolla un argumento lingüístico a favor de la existencia del uso de intuiciones en filosofía, así como su crítica a éste; mientras que en la segunda (caps. 6-11) elabora  un argumento práctico, junto con sus respectivos defectos. Y si bien Cappelen cree que en última instancia la diferencia entre ambos argumentos es convencional, sirve para sus propósitos expositivos.
Margot, J.-P. (2021). Descartes y Spinoza. Universidad Nacional de Colombia, Universidad del Valle
Authors: Díaz Jorge Aurelio
Published: May 2022

El libro recoge siete artículos, cuatro sobre temas de la filosofía de Descartes y tres sobre la de Spinoza, algunos ya publicados y otros inéditos, como lo señalan los Créditos Editoriales, pero con versiones revisadas, corregidas y ampliadas. Aunque cada uno de los capítulos puede ser leído de manera independiente, hay un hilo conductor que los integra, y que no es otro que la confrontación entre el racionalismo moderado del pensador francés y el racionalismo radical del judío de Ámsterdam: “Spinoza quiere acabar con el misterio que rodea la razón o que le subyace –leemos en la contraportada–, misterio que hace afirmar a Descartes en la Meditación tercera: «es propio de la naturaleza del infinito que mi naturaleza, que es finita y limitada, no pueda comprenderlo»”. Se trata así de una de las tensiones básicas que atraviesan todo el pensamiento moderno.
Ciclo de vida y potencial reproductivo de la hormiga depredadora Solenopsis cf. picea (Hymenoptera: Formicidae)
Authors: HERRERA-RANGEL JANINE , ARMBRECHT INGE
Published: May 2022

Solenopsis cf. picea, también conocida como “la negrita”, es una hormiga abundante en los sistemas cafeteros de la zona de Risaralda (Colombia), donde anida en el suelo y se encuentra tanto en cafetales de sombra como monogenéricos. Estudios realizados en campo y en laboratorio han demostrado que depreda sobre la broca del café, convirtiéndola en un organismo que podría ser implementado como control biológico. Este trabajo tuvo como objetivo estudiar algunos aspectos de su ciclo de vida, en términos de desarrollo del inmaduro y aspectos reproductivos del organismo. Se encontró que el desarrollo (reconocimiento cronológico y morfológico) de inmaduros correspondió a un promedio de 56 días. Las medidas de cápsula cefálica agruparon a los individuos en tres ínstares larvales. El promedio de la postura de huevos durante 24 horas fue significativamente mayor en colonias monoginas acompañadas de densidades altas de obreras y la fecundidad individual de las reinas disminuyó con la presencia de otras reinas en una misma colonia.
The Little God of England: The Divine Right of James I and the English Response
Authors: Greenhaw Nathan
Published: May 2022

This paper analyzes the development of James I’s theory of divine right in England and how its application elevated the sovereignty of the monarch to the extent of absolutism in the early seventeenth century. Since divine right ultimately conflicted with the ancient laws and customs of the English government, James’s theory provoked newfound interpretations of the political and judicial authority of the ruler. From a plethora of political treatises, religious sermons, and parliamentary records, these interpretations ultimately affected how governmental institutions, such as Parliament and the courts, interacted with the monarchy. Parliamentarians became more submissive to the king's will, the importance of constitutional law was diminished, and political theories grew more in favor of divine right. As such, by the end of James’s reign, divine right was no longer a theory but rather a political reality, a development which enabled the king to rule with absolute power, all at the expense of parliamentary autonomy, constitutional supremacy, and individual liberty. Therefore, discourse over the true nature of monarchal government not only became more prevalent, but divine right itself became significantly entrenched within the English monarchy. This development altered the English political landscape entirely, inevitably leading the kingdom to civil war in the 1640s and a fervent resurgence of divine right with the restoration of Charles II in 1660. Thus, this paper reveals that divine right during the reign of James I was paramount towards the transformation of the monarchy in early modern England, for it created a myriad of unique and complex understandings of rulership that would ultimately lead to the expansion of absolutism, civil conflict, and political unrest for the remainder of the century.
BTK: A Case Study in Psychopathy
Authors: Hutnyan Matthew S.
Published: May 2022

Psychopathy and serial murder have been topics of great public interest and media attention for several decades. Dennis Rader, a serial killer well-known by his pseudonym “BTK,” was responsible for the gruesome torture and murder of ten people between 1974 and 1991. Although some information is known about him through media accounts, little work has been done to synthesize information about his life and crimes, and to examine him as a case study of psychopathy. Through careful literature review and analysis, this study aims to provide insight into Rader’s life and crimes, and to delineate his psychopathology to gain a better understanding of psychopathy. The results of this case study indicate that Dennis Rader exhibited many features of psychopathy, as well as antisocial and narcissistic personality disorders. This case study has important implications for the public perception of psychopathy and serial murderers, and the investigation of individual psychopaths, emphasizing the value of a comprehensive review of an individual’s life factors in relation to their criminal behavior.

Chlorsulfonylisocyanat: Beispiel der Herstellungspraxis einer hochreaktiven Substanz
Authors: Cieslewski Tomasz
Published: May 2022

The process for manufacture of chlorosulfonyl isocyanate was developed in the Wallis Plant of the Lonza AG in the early 1980s. This reaction involves the two gazeous starting materials SO3 and ClCN. In order to explain the particularities of the reaction as well as of the procedure, it is necessary to focus on physical properties, on the conception of a production plant and on the notion of consecutive reactions. The industrial routine in working with such highly reactive products and equally reactive, even dangerous starting materials is described. In addition to implementing the safty measures from the risk analysis and also from the product-risk profile, which has been developed just for this purpose, one also has to be particularly careful with transportation. High safty and quality standards can be guaranteed by using rather common techniques, as long as safety matters are taken very strictly.
Industrielle Synthese und Umgang mit einem hochexplosiven Produkt am Beispiel des Nitroglyzerins
Authors: Sigrist Markus
Published: May 2022

The first synthesis of nitroglycerine was achieved by Sobrero in 1846 by treating glycerine with a mixture of sulphuric and nitric acid. It is a powerful explosive, but because of many accidents its use in a pure form was forbidden in 1873. Alfred Nobel solved the problem of the high sensitivity to shock by absorbing the liquid in kieselguhr – the dynamite was invented.The risks of nitroglycerine can be summarised as follows:– Risks during synthesis (overheating, incomplete reaction, instability under acidic conditions)– Risks during handling (mechanical shock, rapid heating especially under confinement, freezing below 13°)– Toxicological effects.Most risks can be managed by the following means:– Safety distances to endangered people– Automatic safety systems for nitration plants– Good neutralisation and washing of nitroglycerine– Regular control of stability (Abel Test) and of pH– Transportation only in diluted form, for short distances in emulsions with water– Protection methods for the people exposed to nitroglycerine.

Interactions and cleavage reactions of β-amino acids and β-oligopeptides (up to nine residues, carrying the side chains of Ala, Val, Leu, Ile, Phe, Ser, Lys, and Hop) with biological systems, such as the most potent peptidases (pronase, proteinase K, 20S proteasome), microorganisms (Pseudomonas aeruginosa and Pseudomonas putida), and mammalian blood (intravenous application to rats) have been investigated and compared with ?-peptides. The results are: i) the three peptidases do not cleave β-peptides at all (within 24 h), and they are not inhibited by a β-peptide; ii) except for certain 3-aminobutanoic-acid (β-HAla) derivatives, neither free, nor N-acetyl-β-amino acids, nor β-peptides (offered as sole N and C source) lead to growth of the two bacteria tested; iii) two water-soluble β-heptapeptides (with Lys side chains) were shown to have elimination half-lives t1/2(β) of 3 and 10 h at 100- and 30-ng/ml levels, respectively, in the rodent blood – much larger than those of α-peptides. Thus, the preliminary results described here confirm the much greater stability of β-peptides, as compared to α-peptides, towards metabolization processes, but they also suggest that there may be interactions (by hitherto unknown mechanisms) between the worlds of α- and β-peptides.

This review presents some recent developments in the field of electroanalytical sensors. We first explain the working principle of electrochemistry at the interface between two immiscible electrolyte solutions (ITIES), illustrated by the example of copper transferring through a water/1,2-dichloroethane interface when the ionophore 1,4,7,10-tetrathiacyclododecane is present in the organic phase. The obtained results show that assisted ion-transfer reactions take place with both CuI and CuII, but that the interfacial process is complicated by the fact that CuI disproportionates in water and that CuII can be reduced in the organic phase.Based on the same experimental methodology, a new type of amperometric detector for non-redox ions has been developed using a composite polymer membrane supporting a gelified organic phase that can incorporate an ionophore such as valinomycin. We report here the use of a (o-nitrophenyloctylether)-(poy(vinyl chloride) (NPOE-PVC) gel micro-interface as a detector for cations and anions in ion-exchange chromatography. The main advantage of this approach is that selectivity and sensitivity can be tailored by the choice of the ionophore and by the polarisation potential.This ion detector has also been incorporated in a miniaturised total-analysis system (µ-TAS) fabricated in a polymer sheet by UV-laser photoablation. This microfabrication technique is used for the prototyping of a disposable capillary-electrophoresis microsystem comprising on-chip injector, separation column and electrochemical detector. This system is further used with built-in carbon-ink electrodes for the detection of electroactive species. These microsystems are now under development for immuno-sensor applications.
