Influence of bisphenol A on growth and metabolism of Vicia faba ssp. minor seedlings depending on lighting conditions

The effect of one of anthropogenic pollutants, i.e., 4,4′-isopropylidenediphenol, called 2,2-bis (4-hydroxyphenyl) propane (BPA), at 30 and 120 mg L−1 concentrations in the darkness (DK) or dark/light (DK/LT) on growth and selected elements of metabolism of seedlings and leaf discs of Vicia faba ssp. minor was studied. Treatment with 120 mg L−1 BPA had greater effects which were reflected by increase in the number of necrotic changes in roots and stems as well as in leaf discs and reduction of the length of roots DK and DK/LT, and volume of roots in the DK group. However, minimal and no influence on the fresh and dry weight of roots and stems in plants growing under both types of lighting conditions were observed. In both DK and DK/LT groups these effects were correlated with reduced amounts of storage and cell wall-bound sugars as well as of proteins while in the DK/LT additionally with reduced soluble sugar levels in the roots and increased amounts of hydrogen peroxide and phenols in roots and stems as well as in treatment solutions, where these compounds were released. We suggest that endogenous phenols and BPA can be metabolised in roots and stems to quinones. It seems that TB-1,4-BQ, is the one of that of the five studied quinones. We expect that the results of this paper will help to answer the following question: does the phytomeliorative and phytosanitative V. faba ssp. minor plant is enough to be resistant on negative effects, and to be useful to reduce increasing amount of BPA in the environment?

Book Review: Bijl, P., & Chin, G. V. S. (Eds.). (2020). Appropriating Kartini: Colonial, National and Transnational Memories of an Indonesian Icon. : ISEAS. ISBN 978-981-4843-92-8. 198 pages.

This book dicusses the national, regional, and transnational appropriations of Kartini – a young Javanese woman who lived in Jepara, Central Java, between 1879 and 1904. She is recognised internationally as an iconic feminist and nationalist Indonesian figure and is, after Anne Frank, the most widely-read and influential, (originally) Dutch-language author worldwide in the 20th and 21st centuries. Since 1911, her letters, first published in Dutch as “Door duisternis tot licht” (lit. “Through Darkness Into Light”), have been translated into numerous languages including French, Russian, Japanese, Javanese, Sundanese, and Arabic. There are also several versions of Indonesian and English translations. In the 1960s, a republication of the first 1920 English language translation of a selection of her writings was included in the UNESCO Collection of Representative Works.

A Comparative Study of Religious and Quranic Education from the Islam and the West Viewpoint

Religious and Qur'anic teaching seeks to alter the individuals’ beliefs for a particular type of action and behavior based on the rules of religion, Islam and the Qur'an from the darkness of animalism to the light of humanity. The difference between education in Islam and the West is due to the difference of goals. The view of Islam is fundamentally different from the West one towards human beings, so much so that in these two types of views, the happiness definition for human beings is various. Consequently, educational goals will be different. Islam and the West each regulate their view of the family based on their worldview, and values in the family system are regulated based on this comprehensuive viewpoint. The bottom line is that parenting is a two-way street, just as parents are being educated in the process both as an educational model and as a religious task. The research method is analytical-descriptive in which the information is collected in the form of library –based studyand document references related to the research topic. The results of descriptive analysis of research data indicate that education has been one of the topics of interest to different religions and schools during the centuries and eras and religious and Quranic education has indicators, features, principles, methods and special methods to practice teachings. The religion of Islam and the Qur'an removes its obstacles and deterrents.

Effects of Light and Temperature on Germination of Eggert's Sunflower (Helianthus eggertii)

Helianthus eggertii is a rare perennial sunflower of barrens and open habitats in Kentucky, Tennessee, Alabama, and South Carolina in the United States (U.S.). Despite its delisting in the U.S. Endangered Species Act in 2005, little is known about the germination biology of H. eggertii other than seeds require cold stratification for optimal germination. Knowledge about the germination biology of rare species can aid in the management of natural populations and inform strategies for ex situ seed conservation and propagation. We examined how cold stratification, light, and temperature interact to affect seed germination in H. eggertii, and whether germination proportions varied among populations. At the time of maturity in October, seeds have primary physiological dormancy and require cold stratification or prolonged (> 8 wk) incubation in light at cool (15/6 C) temperatures to germinate. Seeds maintained a light requirement for germination when cold stratified in darkness, but not after cold stratification in light. However, seeds germinated to lower proportions after cold stratification in light relative to darkness, and when incubated at temperatures that mimic summer (35/20 C) compared to late spring (25/15 C). Germination varied widely among populations (23-58%), with plants from more open sites exhibiting lower germination proportions than those from partially shaded sites. Our results indicate seeds most likely germinate in early- to mid-spring, and light promotes germination of H. eggertii. Our results highlight the interactive role of light and temperature in determining seed dormancy break and germination in H. eggertii.

Germinative characteristics of tamarillo seeds (Solanum betaceum Cav.) from red and orange fruits

This study appears in the context of the application of germination tests to samples of tamarillo (Solanum betaceum Cav.) seeds of the red and orange strains, post-harvest of the ripe fruits, to serve as a comparison term to the viability tests of ex situ seeds conserved. Germination tests were carried out in Petri dishes with two treatments that were distinguished by the total absence of light and a photoperiod of 16h of light and 8h of darkness, in a total of six repetitions of ten seeds. The results showed the existence of differences in promotion of Solanum betaceum seeds germination. The germination conditions were decisive, being evident that there is sensitivity to light from the seeds of this species.

THE TACIT CURRICULUM: UNEXPLORED OPPORTUNITY OR APPARENT CHALLENGE IN NURTURING RESILIENCE AND TRUST IN GOD’S SUPERNATURAL POWER AMONG YOUTH?

This article investigated on the role played by the unseen curriculum in developing resilience and real honor for God among youth to help them holistically define their way of life and aspirations amid numerous life challenges. Since time immemorial significant attention has been directed towards the official curricular, but the role played by the veiled curriculum in nurturing young people to endure predicaments and genuinely trust in God’s supernatural power has barely featured in many schooling discourses. This means a good number of Christians are burdened by how best they can inspire young people to trust in the omniscient, omnipresent, omnipotent Creator of the universe but very few, if any, ever think about how the veiled curriculum, can hinder or facilitate young people’s development of resilience and trust in God. In this article the meaning of the concept unstated curriculum and its influences on nurturing resilience and teaching about God’s supernatural power—which when invoked in faith causes the kingdom of darkness to tremble, are discussed. The research employed a phenomenological design, guided by an interview guide with 12 open-ended items followed by extensive probing questions. Two experts examined the interview guide items to determine their clarity, but the researcher also conducted a pilot study among 3 participants (one lecturer and two students) to determine participants’ level of understanding of the interview guide items. The results from the research indicated a remarkable connection between hidden curriculum aspects and young people’s resilience and their grasp of how deep, wide, and high God’s power is in overcoming life challenges.

Circadian Rhythm Sleep Disorder, Jet Lag Type (Jet Lag Disorder)

In biological time disorders, endogenous sleep wake rhythms and also the external light darkness cycle become misaligned. The cause could also be internal (e.g., delayed or advanced sleep section syndrome) or external (e.g., jet lag, shift work). biological time sleep disorders might occur in patients with Alzheimer malady or Parkinson malady and in patients UN agency have had head trauma or cephalism. If the cause is externa l, alternative time unit body rhythms, together with temperature and endocrine secretion, will become out of correct with the light darkness cycle (external desynchronization) and with each other (internal desynchronization); additionally, to sleep disorde r and excessive temporary state, these alterations might cause nausea, malaise, irritability, and depression. Risk of vas and metabolic disorders may additionally be augmented. Repetitive time unit shifts (e.g., because of frequent long distance travel or rotating shift work) are notably tough to adapt to, particularly once the shifts amendment in an exceedingly counter clockwise direction. Counter clockwise shifts are those who shift arousal and sleeping times earlier (e.g., once flying
