Fruit and Flower, The History of Oregon's First Day Care Center, is a history of philanthropy in the field of child care. Using a topical approach rather than a strict chronological method, the text discusses the specific subjects of private philanthropy and public funding as applied to the Fruit and Flower institution. At the same time, it traces the exact growth of that institution through a one hundred year maturing process--from its beginning in 1885 as a girls' club of "friendly visitors" to a modern child care center in 1978. This examination of the evolution of a specific social service institution also incorporates a review of the financial factors which initiated change in a day nursery program, and analyzes how federal funding has impacted the quality of that program.

The increased improvement of weed control throughout the years has led to a decrease in the amount of weed in arable fields. Weeds can be a source of pollen and nectar. Pollinating insects are dependent on a variety of plants for nectar and pollen. This study evaluated the arable field weed flower preference among pollinating insects, through mostly observational studies in July 2020 in southern Sweden. Out of the 12 weed species that were observed, 5 got many visits from pollinated insects, while 4 got almost no visits. From these visits, I calculated which preferences each observed insect group had regarding weed species. I found that Syrphidae preferred Matricaria chamomilla, Apis mellifera preferred Centaurea cyanus and Lamium purpureum, Coleoptera preferred Cirsium arvense, other Diptera preferred Cirsium arvense, and Bombus preferred Galeopsis tetrahit. This indicates that if the weed species Matricaria chamomilla, Centaurea cyanus, Lamium purpureum, Cirsium arvense, and Galeopsis tetrahit are present in a conventional arable field pollinators are benefitted. The weed species Myosotis arvensis, Capsella bursa-pastoris, Thlaspi arvense, and Fumaria officinalis got almost no visits, which indicates that it is not as important to favour these weed species to benefit pollinating insects. Out of the surveyed weed species preferred by pollinators, the species Lamium purpureum and Galeopsis tetrahit had among the highest occurrences in arable fields, which means that these species have the possibility to benefit pollinators if weed control is occasionally abstained for a year.

Geologic mapping of the Jessen Butte 7.5 minute quadrangle and the gathering of structural data throughout the quadrangle was used to determine the paleostress regime during the Laramide Orogeny along the north flank of the Uinta Mountains. The Henrys Fork thrust fault and the Uinta thrust fault are major north bounding faults and within the Jessen Butte quadrangle these faults transfer deformation from one to the other. The Jessen Butte thrust fault is a fault splay that splits off from the Henrys Fork thrust fault. Complex fold geometries were created by the interaction of the faults. Bedding plane orientation, mode I fracture orientation, and fault kinematic indicators were measured throughout the quadrangle. A shortening direction to the NE was recorded by all of these different types of measurements, which match with the proposed regional stress field for the Laramide Orogeny. In a few cases N-S shortening was also recorded in the data, which may be from the local stresses in the area due to pre-existing weaknesses in the basement rocks. Finally, for creation of the cross sections, a positive flower structure model best fit the fold geometry of the rocks in the Jessen Butte quadrangle. This type of fold forms in areas which experience strike-slip motion. This suggests that, at least along the north side of the Uinta Mountains, deformation occurred in a uniform stress field during the Laramide Orogeny, with some influence from the pre-existing weakness inherited from the Precambrian basement.

Senior and the City investigate the question; what does it mean to age with dignity in the city? With recent years of pandemic precautions, as senior citizens were subdivided into a high-index group, a greater focus was set upon their living conditions due to the protection. The protective isolation bore discussions about loneliness and the value of social contact arose.  In my thesis project I have made a case study of the senior living home the Flower Fund. Through my research and the pre-conditions of the Flower Fund I have made three public gestures with the aim to link the activity within the buildings to the public life of the streets-cape without. Proposing architectural means which are effective in creating public spaces that is somehow generous and beneficial for both seniors and the city.

Biennial bearing has been investigated longer and more extensively in apple than in any other fruit tree; however, it remains a serious problem in commercial apple production all over the world. Trees that have become biennial flower profusely and carry a heavy crop in the "on" year, and flower sparsely or not at all and carry little or no crop the following year, the "off" year. Fruit in the "on" year tend to be small, poorly colored, and of low quality, while the few fruit in the "off" year are usually too large, become susceptible to physiological disorders, and also are of poor quality. Without intervention, the crops in both the "on" and "off" years are undesirable and uneconomical. The most common method used by commercial apple growers to try to prevent biennial bearing is chemical fruit thinning, which is an "on" year method of removing a part of the crop before it matures on the tree. In general, growers don't do anything in the "off" year to prevent biennial bearing with the exceptions of fertilizing and pruning lightly. In this study, several experiments were conducted with the cultivars "Braeburn", "Golden Delicious", "Ramey York", and "Fuji" in the "off" year to try and suppress FBI and thus prevent a biennial bearing situation in the following year. The first set of experiments studied the effect of whole-tree and partial-tree defoliation on suppressing spur and lateral flowering and fruit set. Flowering and fruit set were suppressed with defoliation in most cases. Defoliation in early July caused the least amount of flowering the following year and in some cases it was zero. As the defoliation timing and severity was delayed, there was less suppression of flowering and fruit set. Ammonium thiosulfate and Endothal increased flowering but decreased fruit set compared to a control. Gramoxone suppressed flowering and fruit set. In another set of experiments, gibberellic acid (GA) treatments were evaluated to suppress FBI in "off" or light crop years. The GA4+7 treatments suppressed return bloom of both spur and lateral flowers more than the GA3 treatments. The effectiveness of GA declined with delayed application. Both GA treatments reduced lateral flowering the most on the basal 1/3 of the shoot. In a four year study, apple trees were thinned to one fruit per flowering cluster every year from 1997 to 2000. Other trees were thinned to zero fruit or two fruit per flowering cluster in alternate years from 1997 to 2000. Trees thinned to one fruit per flowering cluster had moderate flowering and fruit set the following year. Trees thinned to two fruit per flowering cluster had very little to no flowering the following year. Trees thinned to zero fruit per flowering cluster had a "snowball" bloom the following year. Trees that were alternately thinned to two or zero fruit per flowering cluster were in a biennial bearing situation. / Ph. D.

Durante la transición floral, el meristemo apical del tallo (SAM) cambia su identidad de vegetativo, fase en la que produce hojas y ramas, a inflorescente, fase en que produce flores. Las inflorescencias se clasifican, según la identidad del SAM, en indeterminadas, en las que el SAM crece continuamente durante toda la vida de la planta, y determinadas, en las que el SAM da lugar a una flor terminal. En Arabidopsis, la expresión del gen TERMINAL FLOWER 1 (TFL1) en el centro del SAM impide su conversión en flor y, por lo tanto, la determinación de la inflorescencia. Así pues, TFL1 mantiene la identidad inflorescente del SAM, teniendo, por tanto, un papel clave en el control de la arquitectura de la planta. Esta función de TFL1 está íntimamente relacionada con su particular patrón de expresión. El objetivo principal de este trabajo ha sido la identificación de genes que regulan la expresión de TFL1. Para ello, en primer lugar, se llevó a cabo la mutagénesis con EMS de una línea delatora que contiene un transgén, TFL1pro::GUS, en la que la expresión del gen GUS se encuentra dirigida por las regiones reguladoras de TFL1. Dado al papel de TFL1 en el control de la arquitectura de la planta, el escrutinio se realizó buscando plantas que tuvieran un patrón de expresión de TFL1pro::GUS alterado y, a su vez, presentaran defectos en la arquitectura de su parte aérea. Entre los mutantes seleccionados, la línea 63.1, a la que denominamos moss, resultó ser un mutante hipomorfo del gen ARGONAUTE 1 (AGO1). El mutante moss muestra un aumento de la expresión de TFL1pro::GUS en el SAM, y expresión ectópica en las flores, así como una dramática alteración de la arquitectura de su inflorescencia que parece estar relacionada con el aumento de la expresión de TFL1. Nuestros resultados abren la puerta a la idea de que pequeños RNAs participen en la regulación de TFL1 a través de AGO1. / Fernández Nohales, P. (2011).
