Authors: Myšľan Pavol , Ružička Peter , Števko Martin , Mikuš Tomáš
Published: December 2021

Garnet skarn mineralization was recently studied at the Trohanka locality near Prakovce (Gemeric Unit, Eastern Slovakia). Ca-skarn forms lenticular bodies in green schist environment. It mainly consists of zonal garnets, pyroxenes, amphiboles and magnetite accumulations. Studied garnets are rich in andradite component (up to 89.95 mol. %) with minor grossular component (6.83 - 39.67 mol. %). Strong oscillatory zoning in andradite is caused by substitution of Fe3+ and Al3+. Most pyroxenes are rich in the hedenbergite component. In some cases, euhedral diopside crystals with marginal transition zones (composed of diopside with lower content of Mg2+ and higher content of Fe2+) were found in hedenbergite matrix. Amphiboles are dominantly represented by ferro-actinolite and ferro-hornblende in association with isolated euhedral crystals of ferro-tschermakite and ferro-pargasite. Indistinct chemical zonality of amphibole euhedral crystals is caused by presence of ferro-pargasite in the central parts and ferro-tschermakite in the peripheral parts of crystals.

Authors: Dos Santos Adelcio Machado , Klauberg Ricardo
Published: December 2021

Estudo com objetivo de identificar como a fluoretação do sal para o consumo humano, pode contribuir na saúde da cavidade bucal. Trata-se de um estudo qualitativo, exploratório, de revisão bibliográfica sistemática. Os resultados apontam a preocupação no mundo, em relação à doença da cárie dentária, a partir da primeira metade do século XX. Inúmeros países da Europa e da América Latina adicionam fluoretos ao sal de cozinha consumido pela população, para prevenção da doença. O Brasil optou na década de 1970, pela fluoretação da água pública, mostrando-se indiferente a realidade geográfica do território nacional. Outro aspecto, que chama atenção, é o descumprimento formal de alguns estados no cumprimento da legislação. Conclui-se que o Estado Brasileiro enfrenta uma crise de legitimidade causada por inúmeros problemas sociais, como pobreza e desemprego, refletindo inclusive na área da saúde bucal.
CREATIVITY OF SPIRIDON MIKHAILOV (YANDUSH) AND THE WORLDVIEW OF THE CHUVASH ETHNOS IN THE MIDDLE OF THE XIX CENTURY
Authors: Rodionov Vitaliy G.
Published: December 2021

The worldview of the Chuvash ethnos is a person’s idea of the world formed on the basis of ethnic constants and cultural-value dominants. Being specific to each culture, it created the illusion of objectivity in its bearers. The Chuvash worldview is different in different periods of the ethnos’ life, but thanks to ethnic constants, their structure remains the same at its base. In the Chuvash mythological pantheon of the XVIII century, the main images of the patronizing forces were the God who dwells in heaven and the king who dwells on earth, and the images of the opposing forces were earthly evil spirits and churchmen who moved to the Chuvash villages. In the XIX century, this image changes: a mythological character Pulekhse approached the God, who transformed into the image that has the ability to harm a person, and not bring God-appointed good to him. Such transformations in the mythological pantheon occurred due to a change in the image of the enemy in the socio-cultural space of the Chuvash world. All these processes are well reflected in the scientific works and works of Spiridon Mikhailov (Yandush).
VOLOGDA WOMEN’S MARIINSKY GYMNASIUM IN THE SECOND HALF OF THE XIX CENTURY: THE SPECIFICS OF FOUNDATION AND ACTIVITY
Authors: Baev Andrey A. , Ivanova Tatyana N.
Published: December 2021

The article presents a brief history covering foundation and development of female gymnasiums in Russia in the XIX century and opening the main secondary educational institution for girls in Vologda Region. The relevance of the study is justified by the fact that this educational institution was one of the first of its kind in the Russian Empire. The purpose of the article is to study the specifics of the foundation process of Vologda Women’s Mariinsky Gymnasium in comparison with similar institutions in other governorates and to analyze its activities in the early years of its functioning. The scientific novelty of the study is to identify the chronological stages of the history of Vologda Gymnasium and the role of this educational institution in the further development of education in Vologda. Based on archival information, the article gives the analysis of female students’ composition by their birth status during the second half of the XIX century. These data demonstrate that until the 1870s the proclaimed principle of estates equality in education in the gymnasium was not observed. However, after 1872, the term of study was no longer 6, but 7 years. The 1st grade was divided into two departments, which gave the opportunity for even students with average knowledge to enter the gymnasium. This innovation ensured the estates equality of education in Vologda Women’s Mariinsky Gymnasium. The article analyzes as well the list of academic subjects taught and the Rules of admission to the educational institution prior to the educational reform of 1864 (according to the Memorandum Book as of 1862, 1863) and after it (according to the Memorandum Book as of 1873). Some of the disciplines changed their name to broader ones, which indicates a more extensive material covered by the discipline. For example, grammar and language arts were added to the Russian language, geometry – to mathematics. Vologda Women’s Gymnasium functioned 60 years and played an important role in the development of women’s education in the Vologda Region. Now Vologda Pedagogical College can be considered its original legal successor.
The Novelty of Bohuslav Balbín’s Biographies about Saint John of Nepomuk and their Role in Proving His Veneration
Authors: Kis Tímea N.
Published: December 2021

I am focusing on the attributes of three biographies written about Saint John of Nepomuk by Bohuslav Balbín (1621–1688) Czech Jesuit monk and historian. I am searching for the answer for the question that how can the features of ecclesiastic discipline of cult of saints after the council of Trient and the question of public respect before the canonization be caught out in these texts.This biographies of Saint John of Nepomuk has been written to be more than simple hagiographies. Due to their complexity and structural features they have become suitable to enter into a contoversy with Pope Urban VIII’s Coelestis Hierusalem decree, in which he firmly forbid the veneration of individuals not approved by the Holy See. Balbín wanted to prove it that the veneration to Saint John of Nepomuk has been existing continuously since his death, and its manifestations characterize the contemporary communities as well, finally, this devotion becomes ever more intensive therefore it is not inconsistent with the Pope Urban VIII’s restrictionary arrangements.

Authors: ÇÖLLÜ Baki Can , BARUTÇU Esin
Published: December 2021

İşletmelerin, performans ve verimliliklerini en iyi düzeye getirebilmeleri için örgüt ile işgörenler arasındaki ilişkiye önem vermeleri gerekmektedir. Bu doğrultuda, iki taraf arasında yapılan iş sözleşmelerinin değişen ve gelişen rekabet ortamında yetersiz kalmaya başladığı gözlemlenmiştir. Bu sebeple, taraflar arasında karşılıklı beklentilerin ve yükümlülüklerin olduğu yazılı olmayan psikolojik sözleşme kavramı ön plana çıkmıştır. Psikolojik sözleşmeler, maddi beklentilerin (iş, ücret), yanında manevi beklentilerin (kariyer, zaman, eğitim, sadakat, vb.) olduğu sözleşmelerdir. Psikolojik sözleşmeye uygun davranıldığı durumda işgörenler, örgüte karşı daha fazla güven, bağlılık sağlayacak hatta örgütle kendilerini özdeşleştireceklerdir. Örgütle özdeşleşen işgörenler, örgütle kendini bir görerek, örgütün verimliliğinin ve kazancının artması için daha fazla gayret gösterecektir. Bu kapsamda yapılan bu çalışma psikolojik sözleşme ile örgütsel özdeşleşme arasındaki ilişkiyi analiz etmek amacı ile yapılmıştır. Bu çalışma, Acıpayam Belediyesi personeli üzerinde gerçekleştirilmiştir. Araştırmaya 147 belediye personeli katılmıştır. Araştırma kapsamında yapılan analiz sonucunda, psikolojik sözleşme ile örgütsel özdeşleşme arasında pozitif yönlü orta kuvvette anlamlı bir ilişkinin olduğu görülmüştür.

Animal Protectionist or Animal Anti-protectionist? : Towards a Liberation of Animals from Human Oppression/ Patriarchy: A Textual Reading of Benjamin Zephaniah’s
Authors:   Senior Lecturer, Department of English and Cultural Studies, Faculty of Arts University of Buea, Nsaidzedze Ignatius
Published: December 2021

The purpose of this paper is to examine whether Benjamin Zephaniah’s famous poem “Talking Turkeys” can be labeled an animal protectionist or an animal anti-protectionist poem. Using natural and utilitarian theories of animal rights defenders, the paper argues that in the human animal relationship, the humans are the cause of the problem in the relationship not the animals and that they will benefit more if they make animals their friends. At the end of the study it has been found out that when one reads the poem Talking Turkeys’, one unique vocabulary labels Benjamin Zephaniah as an animal protectionist who shows his admiration for animals which prompts his anthropomorphism towards them as well as his pointing of accusing fingers at us humans/patriarchy for being the cause of the animal suffering and killing. The poet advocates friendship with animals to replace our killing and eating their flesh/meat. On the contrary he advocates we become vegans/vegetarians implicitly when he urges us to feed turkeys with green and beans. He reminds us that turkeys have rights, feel pain and have mums, associations which we should join and they should not be artificially manufactured and should also be allowed to enjoy Christmas like receiving gifts and listening to good music. Humans we are told spoiled Christmas.

Authors: Rodriguez María Florencia , Troitiño Cristian , Romanini Felix Enrique , Secco Anastasia
Published: December 2021

Secondary Sjögren’s Syndrome (SSs) is common in patients with Rheumatoid Arthritis (RA). Objectives: to determine if lymphocytic sialoadenifitis (FLS) is associated with clinical and serological differences in a group of patients with RA and SSs. Methods: patients with a diagnosis of RA and SSs were included, which of them presented FLS in the salivary gland biopsy, clinical and serological characteristics were compared. Results: 88 patients were included, 92% women, mean age of 53 years (SD ± 11.3) and 12.5 years of evolution of RA (RIC 6-7). 63.6% had SLF versus 36.4% who did not. In the univariate analysis, a statistically significant association was found between FLS + and the variables: parotidomegaly, interstitial lung disease, hypergammaglobulinemia, hypocomplementemia, rheumatoid factor, positive ANF, and extra-articular and/ or extraglandular manifestations. In the multivariate analysis, the variables independently associated with the presence of FLS were: extra-articular and/or extraglandular manifestations (OR 5.67, 95% CI 1.6-20), positive ANF (OR 11.7, 95% CI 1.6-83) and hypergammaglobulinemia (OR 21, 95% CI 2.46-179). Conclusion: patients with RA and SSs with FLS have a higher frequency of extra-articular and extraglandular manifestations and serological differences, which would imply a different clinical follow-up.

Published: December 2021

At present the issues related to the prevention of diseases of the 20th century that arise with the development of human society and include external (infection, climate change, ecology) and internal (stressful situations, weakening of immunity, metabolic problems) reasons caused by the modern lifestyle are the topical issues of the world community. A characteristic feature of a modern person’s life is a constant lack of free time, inadequate sleep, a sedentary lifestyle and, most importantly, an unbalanced diet. Taking into account regular stress factors, there is an increased physiological need of the human body for micro- and macronutrients that come with food. The lack of these elements, along with increasing mental and physical stress, leads to poor health and occurrence of diseases. Butter is traditional food in an average person’s diet. Butter is a highly nutritious food product where milk fat is concentrated. Milk fat contains many valuable ingredients such as water, phospholipids, lactose and complete proteins. The development of butter enriched with vegetable fillers is a topical research area. Lemon balm (Melissa officinalis L.) has great prospects as a plant component. The aim of the research is to develop fortified butter. To achieve this goal, the following tasks have been formulated: to assess the effect of Melissa officinalis L. herbal additive on the organoleptic characteristics of the enriched butter; to conduct an experimental assessment of the quality characteristics of experimental samples of butter with Melissa officinalis L. as a fortified product; to determine changes in the quality characteristics of Melissa officinalis L. enriched butter during storage; to develop a recipe for enriched butter with Melissa officinalis L. herbal additive.

Published: December 2021

The tourism industry, including the hospitality industry, which were the first to suffer from the new coronavirus pandemic, found themselves in an unprecedented situation: complete cessation of some businesses due to border closures and self-isolation. For some countries tourism makes up one of the largest shares of GDP and is a key industry, for others, tourism and activities associated with international travel significantly accelerate the pace of economic development. Industry actors need to understand what incentive tools are available now and in the aftermath of the pandemic in order to develop a systematic approach to managing the effects of the pandemic. The purpose of the article is to study and structure incentive measures for the tourism industry in the context of the COVID-19 pandemic. The following methods of scientific knowledge has been used: abstraction, analysis, induction, synthesis. The article substantiates the relevance of the study. Some indicators of the functioning of domestic tourism during a pandemic are considered in comparison with previous periods, in particular, price indices for various types of paid services to the population, the development of collective accommodation facilities in Russia. At the same time, there is a decline in all indicators during the pandemic, which is due to forced quarantine restrictions and the closure of borders in most countries of the world. The most popular measures of state support proposed by the government for the tourism sector are the following: support in obtaining financing, tax incentives, subsidizing operating expenses, subsidies for SMEs (minimum wages), deferral of non-tax payments, consulting and educational support, deferrals and incentives for rent payments, provision of grants and subsidies on a competition, etc. The proposed measures to support tourism in the current environment are new personnel training, assistance in developing a strategy, business development, attracting tourists, assistance in the transition to online, facilitation of activities (tax, financial, regulatory exemptions).

Published: December 2021

Phytochemicals are compounds derived from plants that are assumed to have defensive role against certain disease. They have antioxidants, anticancer, antimicrobial, antifungal, antiviral, antithrombic and anti-inflammatory properties. They have a high specificity to boost the immune system and play important role in the metabolism of hormones. The current study is based on qualitative and quantitative evaluation of total phenolics contents, phenolic compounds, antioxidant potential, free and bound phenolic acids in selected vegetables available at the local market of Hyderabad, Sindh, Pakistan. Two different extraction procedures ultrasonic-assisted base hydrolysis extraction and sonication extraction were used. Total 13 phenolic compounds were found and quantified by high-performance liquid chromatography (HPLC), in which Ferulic acid was quantified in a higher amount of 16.71 mg/g in bitter gourd. Total phenolic contents were determined by using Perklin-Elmer lambda UV/Visible spectrophotometer and higher concentration was found in Bitter gourd 92.56 mg 100/g as compared to Luffa and Brinjal with 79.03 and 66.56 mg 100/g, respectively. The antioxidant activity (DPPH assay) was measured at ?max of 517 nm, results revealed that Bitter gourd possessed the higher antioxidant activity with 182.61 µMol/g followed by Luffa and Brinjal with 112.94 and 82.96 µMol/g. The total Flavonoid contents were higher in Brinjal with 44.32 mg g-1 whereas Luffa and Bitter gourd possess the Flavonoid concentration in the range 38.02 and 34.64mg g-1 respectively, the total tannin contents also higher in Brinjal 31.40 mg/g follwed by in Luffa and Bitter gourd with 25.17 and 21.19 mg/g respectively. Antimicrobial activity showed that, all the extracts are the highly effective against S. aureus as compared to E. coli. Finally, it is concluded that all the selected vegetables are very good sources of Phenolic compounds as well as phytochemicals and should be included in the daily human diet for good health. On the basis of obtained results, it is also suggested that these samples will be further investigated for the determination of fatty acids by GC-MS and liquid chromatography-mass spectrum (LC-MS).

Published: December 2021

Desde el marco constructivista del aprendizaje, basado en métodos activos para el desarrollo de competencias, se presenta una práctica docente efectuada en un espacio natural con maestros en formación, desde las áreas de las Didácticas de Ciencias Sociales, Ciencias Experimentales y Educación Física. El objetivo es cuantificar y analizar el nivel de logro de competencias adquiridas y la valoración didáctica y logística de los participantes. Se recurre a un cuestionario de evaluación y valoración y a una adaptación de la técnica del tendero de los deseos. Los datos, siguiendo una metodología mixta, se analizan cualitativamente y con estadística descriptiva e inferencial, para obtener frecuencias y averiguar si hay diferencias significativas con las calificaciones de clase. Destaca un elevado aprendizaje vivencial, que ha facilitado un aprendizaje trasversal también considerable pero un aprendizaje específico variable según el área de conocimiento, interpretado como resultado de una distinta percepción entre la teoría de clase y la realidad del medio. Así, el desarrollo de competencias ha sido más evidente en Ciencias Sociales (78% del máximo evaluado y sin diferencias significativas con las calificaciones medias de clase), frente a, en el otro extremo, las competencias propias de Educación Física, de menor adquisición significativa que los valores de calificación de clase. Se concluye que las salidas requieren cierta asiduidad para el desarrollo de competencias percibidas como ajenas al medio, especialmente desde un punto de vista interdisciplinar.

Authors: Budianto Bambang Heru , Rokhmani Rokhmani , Basuki Edi
Published: December 2021

The population of the predatory mites Amblyseius deleoni had been decreasing due to continuous use of synthetic pesticides in tea plantations. Therefore, this study aimed to select pesticide-resistant individuals from a wild-type population of A. deleoni and to evaluate whether or not the resistant A. deleoni were still sensible as biological control agents.  We exposed A. deleoni to (propargite), fungicide (copper oxide) and a neem seed extracts. We found that the propargite-resistant predatory mites consumed larvae and nymphs of Tetranychus urticae more than the control (wild type) (P < 0.05).  There was no difference in the number of eggs and adults of T. urticae consumed (P > 0.05). The number of individuals of every stage of T. urticae consumed by copper-oxide resistant A. deleoni was the same (P > 0.05).  In general, there were no changes in food preference in the resistant predators to the 3 of pesticides (P > 0.05). There were slight differences on the pattern of predatory capacity among the resistant predators to the three pesticides.  Although the predators are resistant to the 3 pesticides, it took longer to consume their prey in comparison to the control.  These findings suggested that pesticide-resistant A. deleoni were able to maintain their functions as a biocontrol agent.

HIGHLIGHTS

The effectiveness of Amblyseius deleoni as a natural predators have decreased due to continuous uses of synthetic pesticides to control pests and diseases on tea plantations

Continuous exposure to propargite, CuO and neem seed extracts induced the predatory mites deleoni to develop resistance

No significant changes in feeding preference and the predatory capacity of the mite deleoni on T. urticae after becoming resistant to pesticides

Exposures deleoni to pesticides may have induced heritable epigenetic changes permanently or just reversible phenotypes without changing the DNA sequence

Hypothenar region is an area that is often contacts with surfaces during activities, and the ear is proven to be more consistent than face identification in passive biometrics. While, the teeth are hardest part in the human body which covered inside the oral cavity. These 3 parts of the body have a great role forensic identification especially in determining sex. The aim of this study is to know differences in correlation values in sex determination based on ridge density of hypothenar region of the palm, external ear anthropometric and canine index. This was a cross sectional study with observational analytic design, include 500 medical students in Kariadi Hospital Semarang Central Java Indonesia, age 21 - 26 years old, who are included in inclusion criteria, male (n = 250), female (n = 250). Ridge density is measured by calculating the average number of hypothenar palm ridge on the side of the top, middle and bottom; each area is 5×5 mm2 in measurement. External ear anthrophometric consists ear length, ear breadth, base auricular, lobe length and lobe width. Canine index is calculated by dividing mesiodistal width and intercanine distance in 4 regions. Spearman correlation test between ridge density of hypothenar region palm prints, external ear anthropometric, mandibular canine index and sex shows significant correlation with p-value = 0.000. There is no significant difference between maxillary canine index and sex (right maxillary p-value = 0.112 and left maxillary p-value = 0.082). There are differences in correlation values in sex determination based on ridge density of hypothenar region palm prints, external ear anthropometric and mandibular canine index. Ridge density of hypothenar region palm prints and ear length are show strong correlation in sex determination.

Published: December 2021

Canola is a potential feedstock for the production of biodiesel due to its high levels of energy efficiency. However, Brazil has not yet consolidated its production as typical of temperate regions. Thus, the objective of the study was to evaluate the agronomic performance of canola hybrids in the tropical conditions of the Brazilian Cerrado in order to select promising candidates to contribute to the expansion of canola culture in the country. Eight commercial canola hybrids were evaluated for seven agronomic traits, in three experiments with varying water conditions. The data obtained for each variable were subjected to joint analysis of variance and the averages compared using the Scott-Knott test. The grain yield of the evaluated hybrids was higher than the national average, which includes plantations only in the southern region. The hybrids that stood out in grain yield were Hyola 61 and Hyola 76 followed by Diamond, which besides presenting a high magnitude for this characteristic, was less precocious even in dry conditions.  Due to its characteristics, the Diamond hybrid can be considered the best option to be inserted in the crop rotation system.  These results are promising and reveal adaptation and cultivation potential of these hybrids in the Brazilian Cerrado.
Highlights

The yield of canola grains in the experiments was promising as the values ​​achieved were above the national average.
Hyola 61, Hyola 76 and Diamond showed prominent grain yield in relation to the other hybrids investigated.
Diamond presented high grain yield and shorter cycle, thus being considered the best option for the crop rotation system.
For the Brazilian Cerrado, the hybrids Hyola 61, Hyola 76 and Diamond are valuable alternatives for planting.

Authors: Sampaio de Almeida Déborah , Simone Mendonça Freitas Marta , Cordeiro de Carvalho Almy Junior , André Beltrame Rômulo , Ola Moreira Sarah , Evangelista Vieira Marlene
Published: December 2021

The present study evaluated the effect of arbuscular mycorrhizal fungi (AMF) inoculation on growth and nutrition of Euterpe edulis seedlings, supplemented or not with phosphate fertilization. The experiment was conducted in a greenhouse. The randomized block design, consisted of a 3x2 factorial arrangement and 4 replicates, with two phosphorus doses (0 and 50 mg dm-3 of soil), two microbiological treatments (Rhizophagus clarus;  laroideoglomus etunicatum; R. clarus + C. etunicatum) and control (without fungus). Sowing and inoculation occurred concurrently in 2 kg plastic bags. Height, collar diameter, leaf area, dry shoot mass, macronutrient content and mycorrhizal colonization percentage were determined after 226 days. Regarding mycorrhizal colonization percentage, R. clarus resulted significantly beneficial for the production of E. edulis seedlings. In the absence of phosphate fertilization, R. clarus and mixed inoculum increased all biometric variables and macronutrient contents in seedlings. Therefore, it is concluded that AMF inoculations provide beneficial effects for growth and nutrition of E. edulis seedlings, resulting in more vigorous plants at a low-cost strategy.
Highlights:

Rhizophagus clarus resulted significantly beneficial for the production of E. edulis seedlings and in the absence of phosphate fertilization, and mixed inoculum ( clarus + Claroideoglomus etunicatum) increased all biometric variables and macronutrient contents in seedlings.
The AMF inoculations provide beneficial effects for growth and nutrition of E. edulis seedlings, resulting in more vigorous plants at a low-cost strategy.
The AMF, a biological agent of mutualistic associations with plants, constitutes an innovative approach to sustainable agriculture, contributing to increase plant survival rate, a key-factor for the successful reintroduction and conservation of E. edulis, as well as for its commercial exploitation.

Published: December 2021

Drip irrigation –surface (DI) and subsurface (SDI)– is one of the best irrigation systems to increase both irrigation and water use efficiency. The objective of this research is to assess and compare the response of fodder corn to SDI treatments at two depths with DI in Mendoza. A full factorial experimental design was used on random plots and measurements were replicated through time. Tests were run in two consecutive cycles. Germination percentage (GP), yield, water use efficiency (WUE) and water productivity (WP) were assessed. High yields ranging from 70,214 to 105,771 kg ha-1 of green matter and from 10,020 to 22,476 kg ha-1 of dry matter (DM) were obtained in both cycles, respectively.
DM production from the first sowing was significantly higher in both cycles under SDI treatment than under DI. No significant differences in WP or WUE were found. GP and soil moisture (SM) did not show differences between treatments, but significant differences were found in SM (p=<0.0001) between the first soil layer and the other two layers.
Highlights

Germination percentage was not affected by the depth of the drip irrigation lines.
No significant differences were found in green matter yields between treatments in both crop cycles.
High crop water use was achieved. WUE values were 12 percent (and up to 41 percent) higher.

Published: December 2021

The tight relationship between root architecture and uptake capacity of soil water and minerals, is well established. Support roots, generally long-lived, perform support functions such as transportation and food storage. Absorbing roots, thin and short-lived, absorb nutrients and regulate plant metabolism. Roots distribution in the soil profile is crucial for plant development. It optimizes resource usage and ensures a prompt response to seasonal changes. This work aimed to study the vertical distribution of the root system of nine-year-old oil palms in a haplic Luvisol, low fertility, moderately acidic, with Nitrogen (N) and Potassium (K) deficiency, average content of Phosphorous (P), and medium to low Cation Exchange Capacity (CEC). Using the cylinder method, soil samples were collected every 10 cm and down to 150 cm of soil depth, from each cardinal side of three soil profiles. The results showed that oil palms had good root development. Most roots (73%) were found in the first 30 cm of soil, with a predominance of fine roots (78%). At 50 cm in depth, fine roots represented 88%, thin roots, 67% and medium roots, 94%. Further study should assess root length density at 15, 20, 25, and 30 years.
Highlights
- Haplic luvisols are optimal soils for oil palm cultivation due to their depth (> 150cm), over 50% base saturation, and pH of 5.5-6.6.
- Root length density (RLD) decreased as soil depth increased. Although most oil palm roots are found in surface horizons, roots can still be found at depths of up to 1.5-5 m.
- The highest number of oil palm roots (73%) was found in the first 30 cm, with 78% of fine roots.
- Fine roots were distributed throughout the entire soil profile, evidencing  high nutrient-absorption and metabolic activities.

The objective of this research was to analyze the adoption behavior over time for the improved variety of garlic CEZAC 06, and the factors associated with the adoption process through survival analysis (SA), in North-Central Mexico.  The data comes at farm level and was collected in 2019 through a questionnaire given to 40 garlic farmers in Zacatecas, Mexico.  The results show that 62.5 % of the farmers who adopted CEZAC 06 carried out this process in the first two years after they were first introduced to it.  The factors that played a role in the adoption process were: farmer age, how long the farmer had been in business for, number of hectares availables for garlic production, yield, number of college-educated family members, income from crop farming, income from garlic farming, agriculture-related courses taken, financial aid from the federal government, and being part of any type of organization.  Improving yield and the quality of the garlic bulb requires an adequate extension system that allows farmers to receive updated and reliable information on the importance of technological innovation.
Highlights

The analysis also suggested that new technologies should be transmitted at higher rates to increase adoption. This can be done by implementing courses aimed at farmers with low educational backgrounds, small plots of land and low productivity levels.
The factors affecting the adoption process were: farmer age, how long the farmer had been in business, yield, etc.
CEZAC 06 will increase yield and rural farmers could improve the quality of the bulb as a marketable surplus.
This work contributes to the scarce literature on the application of survival analysis to agricultural technologies.

Ceraeochrysa claveri Navás (Neuroptera: Chrysopidae) is a predator found in several agricultural ecosystems and feeds on insects and phytophagous mites. Its high reproductive potential and forage capacity makes it a candidate for biological control of agricultural pests. Raoiella indica Hirst (Acari: Tenuipalpidae) is an important pest that can damage several species of palms, in particular, Cocos nucifera L. Given the scarcity of available knowledge about the biological aspects of Chrysopidae fed with phytophagous mites, the present work aimed to study the larval development of C. claveri fed mainly with R. indica, in order to obtain information that would be of help in the integrated management of this pest. The evaluation was performed in the F0 generation. Larva 3 is the instar that consumes the most mites (F value = 32.99; P > 0.0001) (L3: 46.80 ± 10.12 a; L2: 9.80 ± 1.23 b; L1: 9.40 ± 1.58 b). C. claveri did not complete larval development when fed only with R. indica. Larval instars L1, L2 and L3 lived 7.4 ± 2.2, 7.6 ± 1.9 and 9.0 ± 3.9 days, respectively. The larvae that reached the pupal stage failed to grow further. When adding Sitotroga cerealella Olivier (Lepidoptera: Gelechidae) eggs to the diet, the development lasted 7.9 ± 0.2, 7.4 ± 0.8, 6.5 ± 0.9 and 13.6 ± 0.9 days for L1, L2, L3 and pupae, respectively. The adults lived on average 6.7 ± 4.9 days. The sexual ratio was rt = 0.42. According to the conditions under which the experiment was carried out, it can be inferred is that C. claveri cannot complete its development by feeding only on R. indica, and that it thus consumes this mite as an occasional prey.
Highlights:

Ceraeochrysa claveri is a predator found in various agricultural ecosystems and feeds on insects and phytophagous mites.
Raoiella indica is an important mite that can damage several species of palms, in particular Cocos nucifera
Ceraeochrysa claveri does not complete its biological cycle by feeding only on indica. By adding another protein source to L3, it can reach the adult stage in 35.4±2.8 days.
Ceraeochrysa claveri does not complete its cycle by feeding only on R. indica and consequently takes this mite as occasional prey.

The macro sector of the civil construction industry is a major consumer of natural resources and it generates impacts, identified as social, environmental or economic, and it is necessary to develop studies that aim to rationalize this raw materials consumption and reduce the impacts generated. Since some resources used in the sector are finite, this work’s main objective is to make the concrete more ecological by replacing part of the fine aggregate of its composition for granulated slag from the blast furnace, reducing the need for sand extraction. For this study, tests were carried out with the co-product and with the fine aggregate, evaluating the properties of the concrete in the fresh and hardened states in three mixture types, the first being a reference, the second with 30% replacement and the third with 60% replacement of fine aggregate with slag. Based on the results obtained, it is noted that the granulated blast furnace slag has more similar characteristics to the sand’s; in the fresh state, the concrete showed a similar result in the three mix types; in the hardened state, it was observed that the performance of the concrete in axial compression was satisfactory; while in flexion traction the two proposed mixtures with substitution presented an unsatisfactory result.

This phenomenological research examined the challenges, coping mechanisms, and success stories experienced by neophyte principals. Key informants were 11 neophyte principals in the Schools Division of La Union and the City of San Fernando Schools Division during SY 2020-2021. Data gathered using a semi-structured interview guide were thematically analyzed. It was revealed that the respondents' most pressing challenges were lack of resources, and difficulties in transitioning to the new school. They addressed these situations by adopting effective leadership strategies involving a mix of professional and technical skills, conceptual skills, and interpersonal skills. They succeeded in strengthening collaboration among the school stakeholders, in achieving school development and improvement goals, and in improving students' academic achievement. It was concluded that the neophyte principals develop improved leadership skills and management practices which enabled them some impressive accomplishments in their respective schools, and gained the cooperation from the teachers, parents, and other stakeholders. Based on these findings, the researcher developed a conceptual model which can be used as a guide in attaining self-efficiency in leadership and management among the neophyte principals. In addition, the researcher also crafted a two-day supportive seminar on developing proactive collaboration between the school and other stakeholders of quality education.
