The Chromosomal Evolution And Analyses Of Turkish Cousinia Species, Tuna Uysal, Osman Tugay, Kuddi̇si̇ Ertuğrul, Meryem Bozkurt, Deni̇z Ulukuş, Hakki Demi̇relma

Turkish Journal of Botany

In this study, Turkish Cousinia species were examined in point of chromosome number and morphology. To our knowledge, this work is the first comprehensive chromosomal study regarding Turkish Cousinia as a whole, especially for endemics. As consistent with previous reports, the chromosome numbers are mostly 2n = 26 and have been determined also as 2n = 24 for only the members of Cynaroideae and Sphaerocephalae sections. An interesting result of this paper is that there is not any polyploid species in this taxonomic group and all of them are diploids. Concerning the chromosome evolution of the Cousinia species, we concluded …

The genus Sphagnum is one of the richest taxa among the Turkish bryophytes. Up to now, it has been represented by 27 taxa in six sections (Sphagnum, Acutifolia, Squarrosa, Subsecunda, Cuspidata, and Rigida). In this study, an identification key for the section Sphagnum was prepared, and the section was investigated using phylogenetic analyses, with a main focus on Turkish bryophytes. This study provides the first sequence data of the trnL intron region for five species of the section Sphagnum from Turkey (namely S. centrale, S. divinum, S. medium, S. palustre, and S. papillosum) to be used in future studies and …


Molecular Phylogeny And Phylogeography Reveal Recent Divergence In The Iberis Simplex Dc. (Brassicaceae) Species Complex, Emre Çi̇lden, Bariş Özüdoğru Jan 2022

Molecular Phylogeny And Phylogeography Reveal Recent Divergence In The Iberis Simplex Dc. (Brassicaceae) Species Complex, Emre Çi̇lden, Bariş Özüdoğru

Turkish Journal of Botany

According to the current taxonomic delimitation, the Mediterranean genus Iberis comprises about 30 species. Among them, the taxonomy and species delimitation of Iberis simplex and its morphologically close relatives (I. attica, I. carica, I. gypsicola, I. halophila, and I. spruneri), described here as the I. simplex species complex, are controversial and several different names are used for the members of this complex. Past phylogenetic studies did not include the members of this complex and here we present the first comprehensive phylogenetic and phylogeographic study based on nuclear ITS and chloroplast trnL-F regions to …


Models Of Motherhood Expansive Mothering In The Old Testament, Avram R. Shannon, Thora Florence Shannon Jan 2022

Models Of Motherhood Expansive Mothering In The Old Testament, Avram R. Shannon, Thora Florence Shannon

Religious Educator: Perspectives on the Restored Gospel

Motherhood, both in the scriptures and in our own experiences, is a wonderful and beautiful thing, but it can sometimes be a fraught category. Societal and religious expectations on mothers can be overwhelming and can lead to despair, difficulty, and marginalization.[1] Motherhood is often defined as a narrow range of nurturing behaviors such as bearing, nursing, feeding, and fulfilling other physical needs of children.[2] Some people have used the Old Testament to proscribe women's roles to motherhood and then to define their roles of motherhood as a limited range of these mostly physical acts of childcare.[3] While these are vitally …


From Stumbling Blocks To Stepping Stones What America Can Learn From Germany About Reconciliation, Melissa Dalton-Bradford Jan 2022

From Stumbling Blocks To Stepping Stones What America Can Learn From Germany About Reconciliation, Melissa Dalton-Bradford

BYU Studies

On December 7, 1970, while in Poland to sign the Warsaw Treaty, German chancellor Willy Brandt visited the memorial to the Warsaw Ghetto Uprising. The towering stone and bronze monument commemorates the bloody confrontation between Polish resistance groups and German military that took place on the eve of Passover in April 1943, when seven hundred Jewish insurgents wielding only pistols and homemade grenades fought against the well-equipped SS, who, in the end, leveled and incinerated the entire ghetto. More than seven thousand Jews died in that uprising, and an additional forty-two thousand were rounded up and deported to concentration camps. …


Molecular Pathology: Potential Biomarkers For The Detection Of Down Syndrome Pregnancies, Raed Garout Jan 2022

Molecular Pathology: Potential Biomarkers For The Detection Of Down Syndrome Pregnancies, Raed Garout

School of Biomedical Sciences Theses

Down Syndrome (DS), also called trisomy 21, is the most common non- lethal fetal aneuploidy that affects 1 in 800 live births. The disease appears mostly due to the existence of an extra copy of chromosome 21. In the UK, the screening of DS is offered to all pregnant women in the antena- tal care program to assess the risk of DS. If the risk is high the women are offered further testing that includes invasive sampling (amniocente- sis or chorionic villus sampling) to confirm the diagnosis. This project aimed to investigate the possibility of applying new methods to screen …

Urban Insect Biodiversity - Effects Of Native Landscaping, Caedmon Morgret, Dave Warners Jan 2022

Urban Insect Biodiversity - Effects Of Native Landscaping, Caedmon Morgret, Dave Warners

Student Papers and Reports

Urban development comes with the cost of destroyed natural habitats. Urban infrastructure flattens entire ecosystems, replacing them with impervious, life-inhibiting constructions.

Alleviating the impacts of urbanization is possible. Green infrastructure mitigates habitat loss by restoring native habitats within urbanized areas. One benefit of green infrastructure is the reestablishment of biodiversity, benefitting plants, animals, and insects alike. Biodiversity creates a healthier habitat and location than urban infrastructure –and lack of biodiversity –does.

To investigate this benefit we performed a pilot study, sampling lawns and curb-cut rain gardens (CCRGs). We compared biodiversity between restored and unrestored urban habitats.

Assessment Of Combined Modality Therapy For Non-Small-Cell Lung Carcinoma: A Simulation Study Concerning Concurrent Chemo-Brachytherapy, Hadi Rezaei, Hesameddin Mostaghimi, Ali Reza Mehdizadeh

Electrical & Computer Engineering Faculty Publications

Although surgery is the treatment of choice for early-stage non-small-cell lung carcinoma, almost two-thirds of patients do not have acceptable pulmonary function for extensive surgeries. The alternative approach for this large group of patients is sublobar resection along with low-dose-rate (LDR) brachytherapy (BT). However, patients with resected lungs have a high risk of recurrence and are often treated with platinum-based (Pt-based) chemotherapy (CT). In this study, we aimed to evaluate the absorbed doses of lung and other thoracic organs, considering concurrent chemo-BT with LDR sources in two modalities: conventional vs. unconventional Pt-based CT. We used the MCNPX code for simulations …

Electrical & Computer Engineering Faculty Publications

The goal of this project is to explore a new method to efficiently remove Pb(II) ions from water by processing Undaria pinnatifida into immobilized beads using sodium alginate and calcium chloride. The resulting biosorbent was characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS). Using immobilized U. pinnatifida, we investigated the effect of various factors on Pb(II) ion removal efficiency such as temperature, pH, ionic strength, time, and underlying biosorption mechanisms. For Pb(II) ion biosorption studies, Pb(II) ion biosorption data were obtained and analyzed using Langmuir and Freundlich adsorption models. It …

The Most Dangerous Branch Of Science? Reining In Rogue Research And Reckless Experimentation In Social Services, James G. Dwyer Jan 2022

The Most Dangerous Branch Of Science? Reining In Rogue Research And Reckless Experimentation In Social Services, James G. Dwyer

Faculty Publications

Most people are unaware how much public policy is either lacking in any empirical-research support or driven by bad research. Political actors motivated by ideology or donor/constituent demands propose new government practices—in areas ranging from policing to funding of treatments for gender dysphoria in youth to welfare-qualification rules—that will greatly impact people’s lives, and if anyone asks what basis they have for thinking the impact will be good, they can readily find some study to support their case. Especially when powerless populations are put at risk, neither the legislative process nor peer review in the publication process provides a real …


Shape Investigations Of Structures Formed By The Self-Assembly Of Aromaticamino Acids Using The Density-Based Spatial Clustering Of Applications With Noise Algorithm, Mehmet Gökhan Habi̇boğlu, Helen W. Hernandez, Şahi̇n Uyaver Jan 2022

Shape Investigations Of Structures Formed By The Self-Assembly Of Aromaticamino Acids Using The Density-Based Spatial Clustering Of Applications With Noise Algorithm, Mehmet Gökhan Habi̇boğlu, Helen W. Hernandez, Şahi̇n Uyaver

Turkish Journal of Electrical Engineering and Computer Sciences

Tyrosine, tryptophan, and phenylalanine are important aromatic amino acids for human health. If they are not properly metabolized, severe rare mental or metabolic diseases can emerge, many of which are not researched enough due to economic priorities. In our previous simulations, all three of these amino acids are discovered to be self-organizing and to have complex aggregations at different temperatures. Two of these essential stable formations are observed during our simulations: tubular-like and spherical-like structures. In this study, we develop and implement a clustering analyzing algorithm using density-based spatial clustering of applications with noise (DBSCAN) to measure the shapes of …

Saving A Child (Exodus 1-2), Kevin L. Tolley Jan 2022

Saving A Child (Exodus 1-2), Kevin L. Tolley

Religious Educator: Perspectives on the Restored Gospel

Exodus is arguably the most essential book in the Hebrew Bible because it depicts the pivotal events in Israel’s history and the definitive institutions of its religion. These themes have reverberated through all subsequent Jewish and Christian history.[1] Nahum Sarna wrote that the Exodus narrative “profoundly influenced ethical and social consciousness” in the Torah and was the “motivation for protecting and promoting the interests and rights of the stranger and disadvantaged of society.”[2]


Capital Discrimination, Ann Lipton Jan 2022

Capital Discrimination, Ann Lipton

Publications

The law of business associations does not recognize gender. The rights and responsibilities imposed by states on business owners, directors, and officers do not vary based on whether the actors are male or female, and there is no explicit recognition of the influence of gender in the doctrine.

Sex and gender nonetheless may pervade business disputes. One co-owner may harass another co-owner; women equity holders may be forced out of the company; men may refuse to pay dividends to women shareholders.

In some contexts, courts do account for these dynamics, such as when married co-owners file for divorce. But business …


Experimenting Upon The Feelings: Maria Edgeworth’S Empirical Approach To Love In Belinda, Emily Hopwood Durney Jan 2022

Experimenting Upon The Feelings: Maria Edgeworth’S Empirical Approach To Love In Belinda, Emily Hopwood Durney

Criterion: A Journal of Literary Criticism

In her 1801 novel/moral tale Belinda, Maria Edgeworth presents a story of love, family, reconciliation, and education in a time when the popularity of companionate marriages was rising in British society along with the acceleration of scientific innovations and advancements. Belinda mixes these two interests of love and science as Edgeworth, empirically minded like her inventor father, frequently has her characters debunk illusion and deceit through induction and logic. Critics, such as Nicole Wright, have argued that Belinda is a far more significant character than is often recognized because of her logic and reason—especially as she helps other characters …

Review Of The Duck Factory: A History Of Waterfowl In North Dakota, By Mike Jacobs And Erik Fritzell, Douglas Johnson Jan 2022

Review Of The Duck Factory: A History Of Waterfowl In North Dakota, By Mike Jacobs And Erik Fritzell, Douglas Johnson

The Prairie Naturalist

It was by geological accident that North Dakota became the heart of duck production in the continental United States. When the Wisconsin glaciation retreated some 11,000 years ago, it left an uneven layer of glacial till over much of North Dakota and nearby states and provinces, an area termed the Prairie Pothole Region. Large blocks of ice in the glacial till eventually melted and formed depressions that became wetlands, or prairie potholes. These were embedded in a matrix of soil that, with millennia of growth by deep-rooted prairie plants, became rich topsoil. The wetlands, surrounded by luxuriant grassland, were ideal …
