Published: September 2021

Liquid smoke method is an alternative to traditional smoking techniques, which aims to reduce polycyclic aromatic hydrocarbon (PAH) levels in the final product by degrading cellulose, hemicellulose, and lignin during pyrolysis of wood using a high-temperature combustion process. Research in liquid smoke is readily available in its application on raw fish product. However, less information is available in the ready-to-serve-product made of fish. Therefore, this study aimed to determine the effects of varying types and concentrations of liquid smoke on the sensory and proximate characteristics of milkfish nuggets, depending on the hardness, deformation, gel strength, organoleptic, and proximate testing. Parametric data were utilized for variance analysis and Tukey’s test. Non-parametric data, such as organoleptic and hedonic data, were analyzed using the Kruskall–Wallis test and the Mann–Whitney test. Varying types and concentrations of liquid smoke were found to significantly affect the hardness, deformation, gel strength, and protein and carbohydrate levels, as well as the organoleptic and hedonic properties on a 9-point scale starting with 1 to 9, with 1 as very unpleasant and 9 very pleasant (p < 0.05), but had no significant effect on the moisture or fat content of the resulting milkfish nuggets (p > 0.05). The best treatment was found to be 3 % re-distillation liquid smoke. Overall, the organoleptic and hedonic properties of milkfish nuggets processed with filtered and double-distilled liquid smoke were acceptable to be applied. Moreover, determining the type and concentration of liquid smoke is important consideration in the production of milkfish nugget in order to produce best physical and chemical qualities. Furthermore, milkfish nuggets were found to contain essential amino acids and fatty acids, which can be obtained when 3 % re-distilled liquid smoke was utilized to produce milkfish nuggets. This finding practically reveals the method and composition of milkfish nugget liquid, which was more likely to have the highest preference for consumers and may open the opportunity for the food industry to develop more derivative products from fish.

Published: September 2021

Cowpea (Vigna unguiculata L.Walp) is an important legume in the hot, dry tropics and subtropics of sub-Saharan Africa, serving a multiple role for the livelihoods of millions of relatively low-income people. The entire plant can be used for either human or livestock consumption and with considerable drought-tolerating capacity. Tender young leaves, green pods and matured seeds are used as human food. Moreover, the crop serves for sustainable soil fertility improvement due to its excellent nitrogen-fixing capacity. However, its production and utilization are limited in Ethiopia partly due to dependence on the conventional agronomic practices and lack of information on its wide ranging uses. This study was conducted to assess the cowpea agronomy and the contributions the crop has in the livelihoods of farmers at Loka-Abaya and Humbo districts of Southern Ethiopia. Multi-stage sampling techniques were employed to achieve the set objectives. Both primary and secondary data were collected to solicit the required information. The data were subjected to descriptive and inferential statistics such as multiple linear regression model using the SPSS Software version 20 and STATA 13. Multiple linear regression model results showed that education, land size, climate information access, credit access, lack of market chain, availability of seed of improved varieties, and pests significantly (P<0.001) affected cowpea production in the studied areas. The trend analysis showed that the cowpea yield and production area coverage is increasing in Humbo District whereas, a decreasing trend was observed at the Loka Abaya. According to the household interview data, about 76 % of the respondents reported a decrease in the cultivated area of cowpea. According to the respondents, lack of access to improved seed and lack of extension support services contributed 79 % and 73 %, respectively to the low yield observed in the area. The majority of the respondents cultivate cowpea as intercropping and rotation with cereals and in the main field with the main purpose to replenish soil fertility (97 %). On the other hand, 62 % of the respondents cultivate cowpea for home consumption. According to the survey result, 48 % of the respondents use the matured grain for consumption. The production trends of the cowpea are highly variable mainly due to less attention paid by the extension systems to boost the yield of the crop, reliance of farmers on local varieties, pest occurrence and poor market chain. Therefore, modern production technologies including the supply of improved varieties of seed with their full production package should be introduced to the area so as to improve the yield and optimize its contribution towards achieving food security.

Authors:   Bells University of Technology, Adelekan Aminat Olabisi , Alamu TA
Published: September 2021

Coconut has a unique taste and aroma and excellent dietary fibre which has potential application in baked products and human nutrition. Bread was baked using wheat flour and coconut flakes at different substitution levels 100% wheat flour (AWB), 80% wheat and 20% coconut flakes (CWB8), 85% wheat flour and 15% coconut flakes (CWB8.5) and 90% wheat flour and 10% coconut flakes (CWB9). Some quality parameters such as proximate, mineral, pasting, sensory and microbiological analyses were determined to find out the most appropriate substitution level that can give better acceptability. The results showed that proximate contents of samples increased with substitution level. Protein content ranged from 12.63% to 10.26%, fat from 2.23% to 6.13% and fibre from 0.23% to 0.29% respectively. There was a significant difference (p< 0.05) in the Calcium content of the flour blends with 20% coconut flakes (CWB8) having the highest value of 16.94m/kg while the control had the lowest value of 10.93mg/kg. Same trend was observed in the magnesium and potassium contents. The pasting properties revealed that 20% blends (CWB8) had the highest peak viscosity, through breakdown and final viscosity. The peak viscosity ranged from 1681 RVU to 2580 RVU and final viscosity from 1689 RVU to 2645 RVU when compared with the control which has 1814 RVU. Sensory evaluation results showed that CWB8 is the most preferred for all attributes determined when compared with other samples. Microbiological study showed that microbial counts of CWB8 had the highest value of 2.66 x 105 cfu/g at ambient temperature which was higher than the permissible limit within one week while samples stored in the fridge and freezer had low microbial counts. From this study, enrichment with coconut flakes increased the nutritional benefits of the bread because of the increased protein and dietary fibre contents which acts as a prebiotic that helps probiotic bacteria thrive and encourages optimal digestion helping to prevent constipation.
Ternary Relational Semantics for the Variants of BN4 and E4 which Contain Routley and Meyer's Logic B
Authors: López Sandra M.
Published: September 2021

Six interesting variants of the logics BN4 and E4—which can be considered as the 4-valued logics of the relevant conditional and (relevant) entailment, respectively—were previously developed in the literature. All these systems are related to the family of relevant logics and contain Routley and Meyer's basic logic B, which is well-known to be specifically associated with the ternary relational semantics. The aim of this paper is to develop reduced general Routley-Meyer semantics for them. Strong soundness and completeness theorems are proved for each one of the logics.

Published: September 2021

Background: The experiment was conducted at the Faculty of Agriculture and Veterinary Medicine, An-Najah National University, Palestine under growth chamber and greenhouse conditions. Methods: To study the effect of NaCl on germination, fifty seeds in each treatment for each cultivar were germinated on a filter paper in petri dishes moistened with the different NaCl concentration levels (0.0, 50 and 100 mM ). To study the effect of NaCl on plant growth and productivity, 2 seeds per variety were grown in 10 liter pots filled with peat moss-sand. Pots were irrigated with the different NaCl levels. Result: The tested Chickpea cultivars showed different tolerance levels in response to NaCl stress levels. NaCl reduced final germination percentage (FGP) and germination index (GI). The highest plant height was obtained by Einalbeda (38.63 cm) in the control group, while the lowest one was found in Arij (28.25 cm) under 100 mM NaCl. NaCl did not affect root/shoot ratio in all genotypes. Reduction in fresh weight ranged between 25.6 and 74.2% under 50 and 100 mM NaCl.

Published: September 2021

Embora o conceito de Metodologias Ativas assuma um status de buzzword, é possível resgatar em sua história antecedentes que remontam à Antiguidade clássica, como por exemplo, o método socrático. Ainda assim, o maior destaque para essa abordagem teórica se dá a partir da primeira metade do século XX, com a tendência pedagógica tecnicista e os estudos sobre o construtivismo social, destacando-se principalmente pela crítica realizada aos modelos de educação tradicionais. Nesse sentido, o artigo em questão é de caráter bibliográfico e tem por base a análise histórica de como as Metodologias Ativas tornam-se uma possibilidade pedagógica a sociedade do século XXI. Em seguida, busca apresentar as principais abordagens dentro das Metodologias Ativas que podem ser utilizadas para o Ensino Remoto na quadratura atual, tendo em vista os anos iniciais do Ensino Fundamental. Discorremos também acerca da necessária formação de professores para atuar com as Tecnologias de Informação e Comunicação, a imprescindível passagem da educação tradicional para o processo de ensino e aprendizagem que contemple Metodologias Ativas, de modo a atender as novas habilidades demandadas pela sociedade vigente. Iniciativa, criatividade, autonomia, entre outros aspectos são essenciais que sejam desenvolvidos desde os anos iniciais do ensino fundamental. Verificamos diante do Ensino Remoto o quanto ainda estamos distantes de práticas educativas que contemplem metodologias ativas associadas as novas tecnologias educacionais.Palavras-chave: Metodologias Ativas.

Published: September 2021

El presente trabajo analiza una propuesta de reutilización de agua proveniente del concreto fresco retornado a las plantas de premezclado. Esta propuesta es dada mediante productos floculantes, los cuales ayudarán a la clarificación del agua concentrada en las pozas de las industrias de premezclado. Asimismo, el agua recuperada tendrá similares características que el agua convencional utilizada, y que posteriormente ingresará al nuevo diseño de concreto, en donde aportará en un 5% en la resistencia del concreto adicional. Por otro lado, se analizó la posibilidad de reutilizar los finos acumulados en el fondo de las pozas, pero estos no aportan resistencia al concreto ya que presenta el cemento ya hidratado; sin embargo, se puede utilizar para otros propósitos. Se realizó un análisis cualitativo y cuantitativo de la incidencia económica, ambiental y legal; en el estudio de aguas de lavado se han analizado parámetros básicos (densidad por pesada diferencial, pH mediante pHmetría, composición química) de tres muestras procedentes de distintas plantas de premezclado para evaluar la calidad de los vertidos. Se proponen soluciones aplicables y mejoras tecnológicas en el proceso de lavado de mixers con el fin de disminuir el volumen de los sólidos arrastrados, sin que ello perturbe el medio ambiente, y posibilitando un ahorro del agua. Por último, con el floculante elegido y los resultados obtenidos se analizará la optimización económica que produce este método para la limpieza de mixers de concreto premezclado.

Published: September 2021

This study focuses on the role of Cognitive Research Trust (CoRT) thinking program in developing critical thinking skills. It aims to contribute to the teaching program in Turkey for inculcating critical thinking skills using a qualitative case study design. For this purpose, 35 grade 5 students from a primary school and their teacher participated in the study. The data were collected through student reflections and teacher views post training for four weeks. Every week, one lesson, four events, and one projects related to the fifth section of the CoRT program “knowledge and feelings,” which is considered to be related to critical thinking skills, were conducted. The findings revealed that the CoRT program achieves important outcomes in critical thinking regarding opinions, which may be directed by feelings, values, and others’ ideas; information may not always be accurate; information should be investigated, clarified, and simplified; information can be acquired through clues and questioning. In addition, the findings also suggested that for the CoRT program to be more effective, the classes should include visuals and examples relevant to learners’ real lives.

Facebook or LMS in Distance Education? Why University Students Prefer to Interact in Facebook Groups
Authors: Esteban Vázquez-Cano  , Paz Díez-Arcón
Published: September 2021

This article describes an investigation into the level of satisfaction among students at Spain’s National Distance Education University (UNED) regarding use of Facebook groups as an environment for learning. Based on a structural equation methodology, the research analyzed the most relevant personal and socio-educational factors that affect satisfaction. The sample consisted of 418 undergraduate and master’s degree students at UNED’s Faculty of Education; participants were consulted in three semesters between September 2019 and January 2021. The results showed that students who participated in Facebook study groups achieved better results than those who did not, and that they interacted more frequently in these groups than in UNED’s official learning management system. The main latent variables that influenced satisfaction with Facebook study groups were the perception of efficacy they elicited as a complement to distance learning by enabling greater interaction with other students, and the feeling of course companionship they provided. The absence of teacher control also influenced student satisfaction, which allowed students to focus on learning and achieving better results in tests and exams.

Published: September 2021

Preeclampsia is hypertension in pregnancy that aﬀects 2% to 8% of pregnancies worldwide and causes significant maternal and perinatal morbidity and mortality. In the pathogenesis of preeclampsia, placental hypoxia plays an important role, associated with excessive trophoblast apoptosis resulting in decreased trophoblast and spiral arteries invasion. This placental hypoxic condition will induce increased expression of Hypoxia Inducible Factor -1-Alpha (HIF-1-A). L-Arginine is a potent vasodilator presumably to improve preeclampsia placental hypoxic conditions and reduce HIF-1-A expression. This study was an experimental study with a parallel-group post-test only design. Thirty-six preeclamptic mice models were divided into 2 groups. The control group (K1) 18 preeclamptic mice model without treatment and the treatment group (K2) 18 preeclamptic mice given L-Arginine. The independent variable was the administration of L-Arginine and the dependent variable is the placental HIF-1-A expression. Statistical analysis used unpaired t-test on normal data distribution, and Mann Whitney test on abnormal data distribution. The mean of placental HIF-1-A expression K1 was 2.47 ± 1.65 with a minimum value of 0.4 and a maximum value of 6.6. At K2 0.93 ± 0.55 with a minimum value of 0.0 and a maximum value of 2.0. Statistical tests showed that the placental HIF-1-A expression in the treatment group was significantly lower than that in the control group (p <0.001). In conclusion, the expression of HIF-1-A in preeclamptic mice model placenta decreased with L-Arginine administration.

Published: September 2021

A safety sign is a sign of equipment to provide protection for workers or visitors in the workplace. American National Standards Institute Z535 (ANSI Z535) is used as a basic guideline for installing safety signs in the workplace because it is more communicative by using global symbols to overcome language barriers. Occupational Safety Division of Manpower and Transmigration Departement, East Java Province (UPT Keselamatan Kerja Surabaya) is a workplace that has a risk of occupational accidents. The preliminary surveys in the area of the 3rd floor of the Division of Occupational Safety (UPT Keselamatan Kerja) Surabaya revealed that there were many sites with insufficient safety signboards. Many of the installed safety signs did not comply with ANZI Z535 standards. This study aimed to evaluate the installation of safety signs compared to the ANZI Z535 standard on the 3rd floor of UPT K2 Surabaya. This was an observational study examining the installation of safety signs. The data were obtained using the ANSI Z535 safety sign checklist. We found 2 out of 5 types of safety signs were in accordance with ANSI safety sign standards with a comparison percentage of more than 66%, such as the notice sign (67.85%) and safety condition sign (75%). Three other types of safety signs were in the unfavorable category with a percentage of less than 66%, such as danger sign (65.63%), warning sign (50%), and caution sign (46.88%). Some sites required additional safety signs, such as warning signs (at distillation site), caution signs (oven, stairs), notice signs (cylinder storage, elevator, chemical warehouse), and safety condition signs (stair, eyewash).

Published: September 2021

Obstructive uropathy is an obstruction of urinary passage which may lead to anuria, a condition where urine production is less than 50 to 100 ml in 24 hours. The varying etiologies and underlying pathophysiology among different cases based on different demographics can make it difficult for physicians to decide the proper management. Therefore, we aimed to evaluate the clinical profile and management of anuria patients in Dr. Soetomo General Academic Hospital over a four-year period. This was a descriptive study with a retrospective approach evaluating all patients with anuria admitted from January 2016 to December 2019. Patient data taken from the medical record were presented descriptively. A total of 176 patients were obtained. Only 161 patients were included. Most of the patients were female (n=100, 62.11%) aged 51 to 60 years old (n=63, 39.1%). Postrenal obstruction due to urinary stone was the most frequent etiology (n=86, 53.4%). Consequently, some patients developed hydronephrosis, which was mostly dominated by the bilateral (n=130, 80.8%) and severe types (n=75, 46.6%). A total of 129 patients (80.1%) underwent hemodialysis. Most of the patients were treated with definitive treatment (n=46, 38.7%). Normalization of renal function mostly occurred in patients who underwent percutaneous nephrostomy (PNS) before giving a definitive treatment.

Authors: Widyatama Rufina Adelia , Irwanto Irwanto , Susanti Dwi
Published: September 2021

Introduction: Fastest developmental period of infants is on their first six months of life. However, smoking is a habit in Indonesia, done mostly by adult male (47.5%) on 30-34 years old group (33.4%) which can harm others, especially their family. Secondhand smoke, defined as environmental smoke that contains more than 4,000 dangerous chemicals, is the major cause of cigarette exposure, and home is the main place where children get exposed. Exposure of secondhand smoke can affect fetal brain, specifically on neurodevelopment stage, which can affect infant development.Methods: This study used analytic observational with cross sectional approach. Sampling method of the study was cluster sampling. This study involved 103 subjects who came to the selected primary health center. Data of smoking family was collected by interview, and infant’s development examination was done by the screening tool Pre-Screening Development Questionnaire (KPSP). Data were analyzed by chi-square correlation test between smoking habit and infant's development.Results: Number of infants in families with smoking habit were dominant which exposed by father is dominant (28.1%), followed by exposure by father and other family members (25.2%), and other family members (7.8%). Infants that were not exposed by secondhand smoke tend to pass the development test (67.5%). There was no significant relationship between infant’s development and smoking family habit (p = 0.128).Conclusion: Although the correlation is insignificant, parents should consider family smoking habit due to infants’ health and development.

ResumenLa práctica del planeamiento urbanístico se apoya en la información sobre el territorio objeto de análisis. A lo largo de los últimos años la producción de esta información por parte de diversas administraciones, y su publicación ha aumentado de manera notoria, en un contexto legislativo que reconoce sus beneficios potenciales para el desarrollo socioeconómico y la participación democrática. Esto tiene como consecuencia una evolución en las metodologías de elaboración de los planes, y el potencial de modificar las dinámicas de interrelación entre los actores de sus procesos de tramitación y seguimiento. El presente artículo plantea una aproximación a estas temáticas, incluyendo casos de estudio a tres escalas (comparación internacional, análisis de escala regional y subregional, y estudio de manzanas).AbstractSpatial planning practice is associated to the available information about the concerned land. Through the last years the production and publishing of such information by many public authorities has thrived in a legislative frame that recognises its potential benefits for socioeconomic development and democratic participation. Plan- making methodologies have therefore adapted, as the links between the actors in the planning production and enactment process can also change. This article defines an approach to these themes, including case studies on three scales (international comparation, regional and subregional analysis, and city block analysis).

Published: September 2021

Wind energy power plants are vulnerable, among others, to abrupt weather changes caused especially by thunderstorms associated with lightning activity and the accompanying severe wind gusts and rapid wind direction changes. Due to a range of damages such phenomena may cause, the knowledge of the relationship between the storm systems and the produced wind field is essential to establish a wind power plant during the construction and operation phase as well. In first part of this study, the relationship of severe wind gusts in regard to lightning activity in a wind farm in a hilly region of western Greece is investigated. Wind data come from wind turbines covering a period of three years (2012-2014), while the corresponding lightning data from the ZEUS lighting detection network. The analysis shows that wind gusts are well correlated to lightning strikes. Furthermore, correlation maximizes during winter when well organized weather systems affect the area and minimum in summer as a result of local storms due to thermal instability. In the second part the study focuses on the development of an ANN model in order to forecast these two parameters in a horizon of 1-h ahead by using except for the wind data, four variables namely CAPE, TTI, wind speed at the 500 hPa isobaric level and the 0-6 km vertical wind shear. The results revealed that proposed model could be considered as a promising tool in simulating the occurrence both of wind gusts and lightning flashes providing a relatively good evidence of the possibility of occurrence of such events.

Communication is indispensable for today's lifestyle, and thanks to technology, millions of people can communicate as quickly as possible. The effect of this breakthrough has transformed organizations to the degree that they generate billions of emails daily to facilitate their operations. There is implicit information behind this vast corpus of human-generated content that can be mined and used for their benefit. This paper tries to address the opportunity that email logs can bring to organizations and propose an approach to discover process models by combining supervised text classification and process mining. This framework consists of two main steps, text classification, and process mining. First, Emails will be classified with supervised machine learning, and to mine, the processes fuzzy Miner is used. To further investigate the application of this framework, we also applied this framework over a real-life dataset from a case study organization.

The present study measured household hunger in South-East Nigeria amidst COVID-19 lockdown. A total of 1209 households (urban and rural locations) were sampled. Household hunger was determined using Radimer/Cornel hunger scale, while Chi-square test was done with significance of P<0.05. Results of this study revealed 82.7% prevalence of hunger among households before Covid-19 pandemic, while during Covid-19 lockdown, hunger prevalence rose to 98.6%. It was also observed that covid-19 lockdown significantly affected food prices.The major coping strategy employed by households was relying on less expensive foods (81.14%). High household hunger was identified as a short term cost of Covid-19 lockdown in Southeast Nigeria. Only few households benefited from the food aid programs and other forms of palliatives by Government. It is recommended that the Government should setup a formidable unit which will develop physical and digital plans for effective implemention during Covid-19 lockdown situation or other emergencies.

Despite extensive investigations of the Depression Anxiety Stress Scales-21 (DASS-21) since its development in 1995, its factor structure and other psychometric properties still need to be firmly established, with several calls for revising its item structure. Employing confirmatory factor analysis (CFA), this study examined the factor structure of the DASS-21 and five shortened versions of the DASS-21 among psychiatric patients (N = 168) and the general public (N = 992) during the COVID-19 confinement period in Saudi Arabia. Multigroup CFA, Mann Whitney W test, Spearman’s correlation, and coefficient alpha were used to examine the shortened versions of the DASS-21 (DASS-13, DASS-12, DASS-9 (two versions), and DASS-8) for invariance across age and gender groups, discriminant validity, predictive validity, item coverage, and internal consistency, respectively. Compared with the DASS-21, all three-factor structures of the shortened versions expressed good fit, with the DASS-8 demonstrating the best fit and highest item loadings on the corresponding factors in both samples (χ2(16, 15) = 16.5, 67.0; p = 0.420, 0.000; CFI= 1.000, 0.998; TLI = 0.999, 0.997; RMSEA = 0.013, 0.059, SRMR = 0.0186, 0.0203). It expressed configural, metric, and scalar invariance across age and gender groups. Its internal consistency was comparable to other versions (α = 0.94). Strong positive correlations of the DASS-8 and its subscales with the DASS-21 and its subscales (r = 0.97 to 0.81) suggest adequate item coverage and good predictive validity of this version. The DASS-8 and its subscales distinguished the clinical sample from the general public at the same level of significance expressed by the DASS-21 and other shortened versions, supporting its discriminant validity. Neither the DASS-21 nor the shortened versions distinguished patients diagnosed with depression and anxiety from other conditions. The DASS-8 represents a valid short version of the DASS-21, which may be useful in research and clinical practice for quick identification of individuals with potential psychopathologies. Diagnosing depression/anxiety disorders may be further confirmed in a next step by clinician-facilitated examinations. Brevity of the DASS-21 would save time and effort used for filling the questionnaire and support comprehensive assessments by allowing the inclusion of more measures on test batteries.

Background: Metastasis is a complex process that involves the spread of the tumor to distant parts of the body from its original site. Metastatic dissemination represents the main physiopathology of cancer. Soluble factors such as cytokines have been closely related to breast cancer (BC) metastasis. Bisphenol A (BPA) is an endocrine disrupting chemical compound with estrogenic properties, which exposure in the early stages of neonatal life leads to an increase in the size and weight of breast tumors and cellular changes in the tumoral immune microenvironment. Methods: Thus, we used female BALB/c mice that were exposed neonatally to a single dose of BPA. Once sexual maturity was reached, a mammary tumor was induced injecting 4T1 cells in situ. After 25 days of injection, we evaluated endocrine alterations, cytokine expression, tissue alterations denoted by macro and micro metastases in the lung, and metastasis-induced cell infiltration. Results: BPA neonatal treatment did not show significant endocrine alterations. Nevertheless, BPA induced a great rate of metastasis to the lung associated with higher intratumoral expression of IL-1b, IL-6, IFN-g, TNF-a and VEGF. Conclusions Our data suggest that cytokines are key players in BC metastasis induction, and that BPA is a risk factor to be considered. This knowledge must be considered with the aim of recognizing environmental pollution in the clinical history of patients to possibly counter BC metastases.

The concern about consuming eco-friendly products has motivated research in the development of new materials. Therefore, films based on natural polymers have been used to replace traditional polymers. This study consists of a production of films based on gelatin reinforced with black pepper essential oil-loaded nanoemulsions and Cloisite Na+. The films were characterized by water vapor permeability, mechanical and thermal properties, surface contact angle, X-ray diffraction and scanning electron microscopy. It was observed that the films containing the nanoemulsion have higher permeability values and an increase in their mechanical resistance. The addition of nanoclay contributed to an increase in the surface hydrophobicity of the film and an increase in the tensile strength at break by about 150%. The addition of essential oil nanoemulsions led to an increase in thermal stability. The presence of clay dispersion contributed to the formation of a surface that was slightly rougher and grainier. The addition of the black pepper essential oil nanoemulsion resulted in an increase in porosity of the gelatin matrix. Through X-ray diffraction analysis, it was possible to conclude that both the polymeric gelatin matrix and the essential oils nanoemulsion are intercalated with the clay dispersion.

Members of the insect ATP binding cassette transporter subfamily C2 (ABCC2) in several moth species are known as receptors for the Cry1Ac insecticidal protein from Bacillus thuringiensis (Bt). Mutations that abolish the functional domains of ABCC2 are known to cause resistance to Cry1Ac, although the reported levels of resistance vary widely depending on insect species. In this study, the function of the ABCC2 gene as putative Cry1Ac receptor in Helicoverpa zea, a major pest of over 300 crops, was evaluated using CRISPR/Cas9 to progressively eliminate different functional ABCC2 domains. Results from bioassays with edited insect lines support that muta-tions in ABCC2 was associated with Cry1Ac resistance ratios (RR) ranging from 7.3- to 39.8-fold. No significant differences in susceptibility to Cry1Ac were detected between H. zea with partial or complete ABCC2 knockout, although highest levels of tolerance were observed when knocking out half of ABCC2. Based on >500-1,000-fold RRs reported in similar studies for closely related moth species, the low RRs observed in H. zea knockouts support that ABCC2 is not a major Cry1Ac receptor in this insect.
