Kontribusi Orang Tua Dalam Pembelajaran Luring Selama Pandemi Covid-19 Pada Siswa Kelas III B Di SDN 136/II Sumber Harapan

This research is a problem in offline learning. Where some students who are active while attending lessons at school they get good learning outcomes but when given offline learning assignments they get low learning outcomes. This study aims to find out about the form of parental contribution in offline learning during the covid-19 pandemic. This research is a descriptive qualitative research type, conducted in class IIIB SDN 136/II Sumber Harapan in the even semester of the 2020/2021 academic year. Sources of data in this study were parents and students of class IIIB. Data collection techniques used in this study are interview methods and documentation methods. Data analysis is done by collection, reduction, display and verification. The results obtained are the form of parental contributions consisting of four contributions, namely: As caregivers and educators including scheduling children's study time and reminding children to do school assignments, as mentors including accompanying children while studying and overcoming children's difficulties in offline learning, as a motivator including parents can motivate by giving praise or gifts for positive things that have been done by children, as facilitators including parents can provide facilities such as books, worksheets, android mobile phones, internet quota. The obstacles faced by parents in offline learning during the COVID-19 pandemic are: parents do not understand the content of the subject matter, parents have little time to accompany their children to study, facilities are inadequate or limited, and children are difficult to teach by their parents.

Parental contribution to trisomy in heterozygous androgenetic complete moles

Complete hydatidiform moles (CHMs) comprise a proliferative trophoblastic disorder and are known to be androgenetic and diploid. Androgenetic CHMs are classified as having monospermic and dispermic origins. Rarely, some CHMs have other genetic constitutions, such as biparental diploid or tetraploid. Previous studies have shown the possibility that androgenetic heterozygous CHMs have an additional chromosome with high frequency. This study aimed to comprehensively analyse the molecular karyotyping of androgenetic dispermic CHMs and the parental contribution of their additional chromosomes. Single-nucleotide polymorphism arrays were performed with the genomic DNA of CHMs and patients. The B allele frequency and selected B allele frequency plotting of CHM were visualised. Among the 31 dispermic CHMs, eight showed trisomy and one showed double trisomy; of the 10 additional chromosomes, seven were of maternal original and three were of paternal origin. In addition, three disomic chromosomes comprised one maternal and one paternal chromosome, although these should theoretically have had two paternal chromosomes in the case of androgenetic CHMs. The subclassification of heterozygous CHMs, with or without maternal contribution, is a new approach and could be a candidate indicator of gestational trophoblastic neoplasia risk.

Etologia ecologico-evolutiva a amfibienilor: sinteza conceptuala a rezultatelor investigatiilor la nivel regional si european

Following from long investigations of more than 50 populations of amphibians from the Republic of Moldova and Italy were elucidated ecological particularities and evolutionary reproductive behavior of some species of Caudata and Anura Orders. For the first time, on Autecological & Sinecological level, has been made assessment of nuptial systems of amphibians – of parental contribution, reproductive success, „r” & „K” reproductive strategies and their role in sexual selection and evolution the attainment of reproductive potential as a fundamental mechanism of survival of amphibian populations in various ambient conditions.

Genetics, molar pregnancies and medieval ideas of monstrous births: the lump of flesh in The King of Tars

The medieval English romance The King of Tars gives an account of a birth of a lump of flesh. This has been considered as fantastic and monstrous in past literature, the horrific union of a Christian and Saracen. However, while the text certainly speaks to miscegenation, we propose that this lump of flesh is actually a hydatidiform mole. We trace the hydatidiform mole from antiquity, surrounding it with contextual medieval examples, from theology, history and medicine, that also describe abnormal births as ‘lumps of flesh’. By discussing medieval ideas of monsters as a warning sign, we interpret the lump of flesh in terms of abnormal births, seed transmission, parental contribution and sin. Ideas of warning, blame and intervention present themselves as a response to moles both in medieval texts as well as in modern reactions to hydatidiform moles. We explore the epigenetics of hydatidiform moles and relate them to the medieval text. In The King of Tars, the fault for the lump of flesh could reside with either parent; we find that this is also the case in the genetic formation of the hydatidiform mole; we also argue that the epigenetics supports medieval theories of seed transmission.
