Mexico is the world's leading producer of Opuntia ficus-indica. This kind of prickly pear is the most widespread and most commercially important cactus in Mexico. Morphological and colorimetric descriptors are among the most important agronomic traits because these parameters affect the yield, in such a way, the objective of the present research was to present a fast and reliable methodology to obtain the functional relationship in shape and color parameters of O. ficus indica cladodes, using a smartphone, a color meter, and open-access software. The acquisition and processing of images discovered interesting relationships between the Opuntia cladode's morphological characteristics, as well as colorimetric parameters of the cladodes. The non-linear data behaviors were fitted using deterministic models and CurveExpert software. Results of the study revealed that the best morphological descriptors were Circularity vs. Perimeter (r= 0.9815) and Aspect ratio vs. Roundness (r= 0.9999). In addition, mean values of the L*, C, and H color parameters were displayed in a window of a computer program online. It was found that the a-C relationship of the color parameters had the highest correlation coefficient (0.999). Therefore, it can be concluded that the morphological descriptors Circularity vs. Perimeter, Aspect Rate vs. Roundness, and a*-C color parameter can predict quickly and precisely the quality of O. ficus-indica.

This study aimed to investigate the effect of nano-Ca fertilizer on nitrogen uptake, nitrogen use efficiency and determine the best calcium form and dose for mango. A pot experiment was conducted using two year old mango seedlings (cv. Zebda). The pots were filled with sandy soil (8 kg per pot) and one seedling was transplanted into each pot. Four treatments including nano-Ca, convention Ca, soil application and foliar application have been formulated. Calcium was applied as CaO for both the convention and nanoforms. The enriched (15NH4)2SO4 was applied at a rate of (5g per pot). Plants were harvested at the end of the fall, spring, and summer growth cycles and dried at 70 oC. The dried plant is used for making fine powder and to determine total nitrogen, calcium, and %15N atom excess. Results of the study revealed that in all growth cycles, the 15N translocation was higher under foliar nano-Ca treatment than under convention Ca at a 100% rate. The highest uptake, translocation, and nitrogen use efficiency were observed at 50% (250 mg. L-1) foliar nano-Ca treatment in all cycles. In the Fall growth cycle, the values for nitrogen fertilizer use efficiency at 50% nano-Ca rate was 81.8%, while it recorded 64.9% for 25% rate and 51.2% for 100% rate. Calcium concentration, in shoot and roots, was also higher under nano-calcium (for fall cycle = 3.0 for the shoot and 2.8 for root) than the convention calcium (for fall cycle = 2.7% for the shoot and 2.2 for root) for all cycles. The summer growth cycle recorded the highest total biomass under all treatments compared with the fall or spring growth cycles. Allocation of biomass to the shoot was also reported higher under nano-Ca foliar application than that of soil application in all cycles. The best treatment is 50% (250 mg.L-1) foliar nano-Ca as it resulted in the highest N-15 uptake, translocation, and nitrogen use efficiency. Nano calcium proves to be more efficient as fertilizer than conventional calcium.

Published: May 2022

Cinnamomum tamala, commonly known as tej patta is widely used as a spice in Indian cuisine for its aroma and flavoring property as the leaves contain essential oil. The essential oil is extracted with the help of the Clevenger apparatus using dry leaves. This oil is mainly used as medicine for releasing gas as well as a carminative agent and diuretic agent. It also improves the digestive system and helps in increasing appetite. This study aimed to determine the phytochemical properties and antibacterial potential of different extracts (aqueous, methanol, and acetone) and oil of C. tamala leaves. The phytochemical evaluation shows the presence and absence of alkaloids, flavonoids, phenolic compounds, steroids, tannins, glycosides, terpenoids, saponins, proteins, and carbohydrates in the aqueous, methanol, and acetone extracts. The efficacy of antibacterial properties of prepared extracts was examined against E. coli and Salmonella typhi (gram-negative bacteria) and Staphylococcus aureus and Bacillus subtilis (gram-positive bacteria). These bacterial cultures were obtained from IMTech Chandigarh. From the results of the antibacterial study it has become evident that among three extracts, the maximum zone of inhibition was obtained in the aqueous extract which was followed by methanolic and acetone extract. With the help of a Clevenger apparatus, Bay leaf oil was extracted to establish antibacterial properties. Henceforth, to analyze the antibacterial potential of the oil sample, the test was performed against the mentioned bacterial species (E. coli, Salmonella typhi, Staphylococcus aureus, and Bacillus subtilis) and reported significant antibacterial activities. From the outcome of this study, it has become clear that Bay leaf oil has potent antibacterial properties against selected bacterial species.
Oralidade e formação docente
Authors: Nonato Sandoval 
Published: May 2022

Este estudo propõe refletir sobre o lugar da oralidade na formação docente, focalizando a produção de breves episódios de práticas de ensino – chamados de microaulas orais – por estudantes de curso de graduação em Letras. A hipótese é de que os processos de formação inicial para a docência constituem-se pela apropriação de gêneros textuais cuja incorporação tanto permite certo exercício do trabalho de ensino pelas estudantes, quanto subsidia o incremento de suas práticas de letramento. Do ponto de vista teórico e metodológico, a abordagem das microaulas orais como gênero textual da formação docente convoca uma dupla perspectiva (didática e interacional), tomando por base a noção de gesto didático como dispositivo analítico. A descrição e análise de uma microaula em sua configuração composicional global e de alguns recursos textuais implicados em sua formulação permitem levantar elementos para a compreensão dos modos como as estudantes representam a ação central de seu futuro trabalho – a experiência de ensinar.

Introduction: Dentinal hypersensitivity is a pathological condition with an increased incidence among patients of various ages, affecting their well-being and with a common response for a wide range of treatment strategies.
The study aimed to assess the impact of teeth hypersensitivity on the quality of life, daily activities, and on the emotional status of the patients affected by it.
Method: We conducted an anonymous survey on a group of 200 patients with ages 20 and 65 years old, using a questionnaire that included 23 questions. The results were collected and statistically analyzed using the chi-square test.
Results: Out of all the patients who answered our questionnaires, 51 percent have ages between 20-25 years, 26 percent between 26-35 years, 12 percent between 36-45 years, respectively 11 percent represent patients older than 46 years. 81 percent of patients are female, and 19 percent are male. In 65 percent, the onset of dental hypersensitivity sensations is caused by the consumption of ice cream, affecting the patients‘ lifestyle negatively. According to the study, 36 percent of patients give up on certain foods/drinks that led to the appearance of dentinal hypersensitivity sensations. Forty-one correspondents felt compelled to give up consuming cold food, and carbonated and sour drinks.
Conclusions: Dentin hypersensitivity is represented by the appearance of an uncomfortable sensation due to dentin being exposed to the exterior environment, a sensation that can range from mild irritation to severe pain and can reduce the quality of mastication and oral hygiene.

Authors: Rodriguez-Arango Rafael Olavarria 
Published: May 2022

This article describes an electrical energy storage system with a heat pump and steam accumulators or molten salt storage, and solutions are proposed for the hybridization of this storage system with power plants, mainly combined cycle and renewable, already existing or new construction.
As a result of the development of these solutions, it is concluded that these hybridizations allow each one of the plants to operate with its nominal performance in peak hours and with a similar or higher performance in off-peak hours or periods of low prices, that is, , the electrical energy supplied to the network for each thermal or electrical kilowatt that feeds the plants is similar or higher when this electrical energy is previously stored. These high efficiencies after storage are achieved by combining heat pump performance (COP greater than 2) and Rankine cycle heat rate.
In summary, it is possible to optimize the performance of the power plants during all hours of the day and optimize costs due to the joint use of equipment and systems.
Highlights
Hybridization combined cycles, renewables and electricity storage can become a useful tool.Hybridization can optimize the joint operation of the electrical system.
Proposed hybridization achieves the same performances after storing the energy. Proposed hybridization allows sharing of equipment and systems.
