Using Integrin Αvβ6-Targeted Positron Emission Tomography Imaging To Longitudinally Monitor Radiation-Induced Pulmonary Fibrosis In Vivo, William C Y Lo, Cristian W Villas Boas, Truc T Huynh, Amanda Klaas, Felicia Grogan, Lori Strong, Pamela Samson, Clifford G Robinson, Buck E Rogers, Carmen Bergom

2020-Current year OA Pubs

PURPOSE: Radiation-induced pulmonary fibrosis (RIPF) is a potentially serious and disabling late complication of radiation therapy. Monitoring RIPF progression is challenging due to the absence of early detection tools and the difficulty in distinguishing RIPF from other lung diseases using standard imaging methods. In the lungs, integrin αvβ6 is crucial in the development of RIPF, acting as a significant activator of transforming growth factor β after radiation injury. This study aimed to investigate integrin α

METHODS AND MATERIALS: We used a focal RIPF model (70 Gy delivered focally to a 3 mm spot in the lung) and a whole lung …

Constanto Mysterium - A Paradise Of Shifting Constants, Vijay Fafat

Journal of Humanistic Mathematics

Mathematicians speak of constants of mathematics. Some of these constants are known to high-heavens. Some remain hidden in the obscurity of erudition. And to be frank, while every real number is a mathematical constant, we don’t know much about most of them (is not the set of transcendental numbers incommensurable without us knowing or understanding very many of them?).

So what elevates some constants above others? Is this elevation just a measure of the ignorance of mathematicians who have explored but a small patch of an infinite quilt, a case of six wise men trumpeting the – well, the trumpet …

White Horses In The Sky: Or The Magical Place Where Topology Meets Poetry, Sanziana Caraman, Lorelei Caraman

Journal of Humanistic Mathematics

What do Shakespearean words, doughnuts, cups of tea, and horses in the sky all have in common with a famous theorem? To discover the answer, we take you on a journey in a strange, enchanted land: the land where mathematics meets poetry. Here we explore how a fundamental literary trope, metaphor, and a fundamental result in topology, Brouver's Fixed Point Theorem, touch and illuminate one another. Delving into the symmetry of this transdisciplinary embrace, we find that it reveals, not only the beauty of poetry and mathematics, but that of life itself: the beauty hidden in ordinary things like a …

Prompting Progress: Authorship In The Age Of Ai, Edward Lee

Florida Law Review

This Article examines a question of profound importance today: do the works people create using artificial intelligence (AI) qualify for copyright? This Article explains why the Copyright Office’s 2023 guidance excluding AI-generated works from copyright is wrong. The Office’s newfound requirement of the so-called “traditional elements of authorship”—including sufficient control, avoidance of random elements in the creative process, prediction of the final work ahead of time, and dictation of the specific results—finds no support in the text, history, or structure of the Progress Clause, Supreme Court precedent, or the Copyright Act, past or present. It limits “Authors” to “traditional elements” …

Calliandra Calothyrsus - A Potential New Shrub Legume For Tropical Animal Production?, B Palmer, R A. Bray, T M. Ibrahim

IGC Proceedings (1977-2023)

Calliandra calothyrsus outyielded leucaena in cutting experiments at 2 sites in northern Australia and I in Indonesia. Drying significantly depressed the voluntary intake and digestibility of leaf, possibly due to the presence of tannin. Calliandra has the potential as a supplement for the low quality grass common to the tropics both ln grazing and cut-and-carry systems.

Advances In Research And Development With Sylosanthes And Other Tropical Pasture Legumes, D F. Cameron, C P. Miller, L A. Edye, J W. Miles

IGC Proceedings (1977-2023)

The last 20 years have seen major advances in research and development wilh tropical legumes. Research advances have been closely associated with substantial increases in the number and diversity of genetic resource collections, Release of a wide range of new cultivars has been based on selection for plant adaptation, persistence and productivity, screening for resistance to pest's and diseases, and the development of efficient seed production. Determination of fertiliser requirements and grazing management practices has resulted in sustainable animal production from legume-based pasture systems. Extensive pasture development has now occurred in both high and low input systems. Options vary from …

Integration Of Wildlife And Cattle On Communal Lands In Kangwane, South Africa, M Stalmans, A Van Wyk, M T. Mentis

IGC Proceedings (1977-2023)

The feasibility of integrating wildlife with the current livestock husbandry on communal lands in KaNgwane was investigated. Present stocking rates were 3 times the recommended figure for production farming. This fitted predictions based on the Jones-Sandland model for populations where the major consideration is maximum number of animals rather than high productivity. The integration of game was seen as a means to increase economic output, while spreading benefits from the use of natural resources to the community at large and establishing a form of ecologically sustainable land use. The active involvement of the community in the planning process and their …

Game Production On Private Land In South Africa, J C. Pauw, M J.S Peel

IGC Proceedings (1977-2023)

The game industry on private land in South Africa has grown considerably in the last 30 years, resulting in a greatly increased biodiversity on private rangeland. However, animals are not domesticated and management is difficult. Management becomes even more complex because commercial game production normally involves a number of species, including domestic stock, in the same production system. Mixed livestock-game ranching holds certain advantages for management and is generally perceived to be more profitable than either alone. Because of human preferences, a lack of clearly defined management objectives and lack of practical management recommendations, veld is generally heavily utilised and …

Overcoming Limitations On The Productivity Of Browsing Ungulates In Africa, Norman Owen-Smith

IGC Proceedings (1977-2023)

In African savannas primary production by woody plants may match that by the grass layer. However, maximum population levels attained by browsing ruminants are only one tenth of those reached by similar sized grazers, The productivity of browsers is limited because (I) much foliage is out of reach, and dispersed by wind when shed; (2) most palatable trees are deciduous, leading to a food bottleneck during the late dry season; (3) leaves of many woody species are rendered unpalatable, indigestible or toxic by plant secondary metabolites. Management actions to overcome these limitations include (I) lopping trees to restrict their height; …

Economic And Ecological Features Of Livestock And Wildlife Utilization In Africa, J I. Barnes

IGC Proceedings (1977-2023)

This paper looks at livestock and wildlife utilisation in Africa within the framework of total economic value (TEV), which includes both utilisation and biodiversity values. In Africa, traditional use of wildlife involves open access systems on public land, Here, free ranging, public wildlife resources are used to produce subsistence or marketed meat and skins at smaII scale. Traditional livestock systems involve open access use of rangelands. Here, livestock are kept at small ·scale to produce draft power, milk, meat and as a store of .value. Commercial use of wildlife involves restricted access systems on both public and private lands. Here, …

Conservation Of Biodiveristy In Managed Rangelands, With Special Emphasis On The Ecological Effects Of Large Grazing Ungulates, Domestic And Wild, Patrick Duncan, Peter J. Jarman

IGC Proceedings (1977-2023)

Biodiversily with its different components (genes, species and ecosystems) is defined in relation to rangelands, whose Importance in its conservation is described. At the fine scale grasslands are much more diverse than tropical rain forest, and are comparably diverse at a regional scale, at least in Africa. Rangelands are crucially important world wide for 1he conservation of plants, and also for birds and large mammalian herbivores. Large ungulates (and other large herbivores) ace "keystone" species in these·ecosystems, playing a crucial role in the maintenance of diverse communities of plants, birds and invertebrates associated with such grasslands. Modification of the natural …

Productivity Of Silvipastoral Areas And Management Needs In Arid Regions Of India, N C. Jain

IGC Proceedings (1977-2023)

In an extremely arid state of India (Rajasthan) having high livestock concentration and vast degraded lands, the State Forest Department has developed community and forest lands into silvipastoral areas by sowing grass (mainly Cenchus ciliaris and C. setigerus) in association with trees. Surveys have revealed high variability in pasture establishment and productivity in different regions. Cenchrus established well in most regions, except the extreme south, if proper sowing methods with closer spacing were followed and soil conservation measures undertaken. Closure from animals helped in favourable grass succession. Establishment of Dichanthium annulatum and Stylosanthes hamata was relatively poor, Analysis of …

Sheep And Forage Productivity In Rubber Plantations, I Tajuddin, D T. Chong, K F. Ng, W W. Stur, H M. Shelton

IGC Proceedings (1977-2023)

The concept of integration of sheep with rubber plantations for weed control and meal production is rapidly gaining recognition in Malaysia. A series of experiments were set up with ACIAR support to determine the level of forage and animal production achievable in rubber plantations and to introduce and evaluate new forage germplasm for sheep grazing under rubber. These experiments showed that (i) the productivity of the currently used cover crops and naturally occurring further as rubber trees matured, (ii) the proportion of the unpalatable cover crop Caloponuim caeruleum increased rapidly with sheep grazing in immature rubber, (iii) reasonable sheep live-weight …

Pastures As The Secondary Components In Tree-Pasture Systems, Chin Peng Chen

IGC Proceedings (1977-2023)

The multi-stata canopy structure of rain forest allows only I% sunlight penetration, too little for the survival of forage beneath it. However, man-made forest plantation (rubber, oil palm and coconut) allows more light for forage species. Initially, 60-70 forage species were recorded under these modified forest canopies but only one third of them survived heavy shading. Forage dry matter yields declined from 2.8-4.8 I/ha DM at immature phase of plantations, to 0.1-1.0 I/Im at mautre phase. Nutrients. available to grazing animals from forages under plantations were guile high (18.4 kg Nit DM and 5609 MJ MEit DM) from native forages, …

Grazing Potential Of Desiccation-Tolerant Tropical And Subtropical Grasses, Y A. Sutaryono, D F. Gaff

IGC Proceedings (1977-2023)

Some desiccation-tolerant grasses possess the potential for use as a grazing source for animals. Some species compared favourably in nutrient content and digestibility with other tropical animal fodder grasses. The Sporobolus species, S. aff, fimbriatus, S. lampranthus, S. pellucidus, together with Eragrostis invalida and Eragrostiella nardoides showed the most promising combination of desirable characteristics. Resurrection grasses contained potentially toxic substances, but, it appears, in amounts harmless to animals, Animal feed trials are needed to test their real feed value, palatability and non-toxicity to animals.

Mixed-Species Grazing In The Highland Sourveld Of South Africa: An Evaluation Of Animal Production Potential, M B. Hardy, N M. Tainton

IGC Proceedings (1977-2023)

The effects of mixed-species grazing, at 5 cattle to sheep ratios all at the same stocking rale, on individual animal mass change/ ha mass change/ Ila were monitored for 2 grazing seasons, The ratios were balanced in terms of animal units which equate the expected intake of cattle and sheep. The study was conducted on a humid grasslands in which the herbage characteristically loses quality as Jt mature1. Mass gains of individual cattle were higher when the cattle grazed 10ge1her with the sheep than when they grazed alone. This was ascribed to increasing herbage availability as the ratio of cattle …

Prediction Of Live-Weight Gain Of Cattle Grazing Pastures On Brigalow Soil, M Hirata, C K. Mcdonald, R M. Jones

IGC Proceedings (1977-2023)

A model for predicting the live-weight gain-(LWD) of cattle from climatic conditions and pasture and cattle attributes was developed. The model was calibrated and validated against the data from a long-term grazing experiment on brigalow soil, sown with green panic pastures. When validated, the model tended to overestimate LWG as the proportion of green panic (Panicum maximum var. trichoglume) in the pasture decreased, because the model was calibrated, without considering species composition, to data from years when green panic was dominant. This study emphasises the limitations of empirical models of grazing systems. The study also implies that there …

Animal Feed Research In Eastern And Southern Africa: Historical And Actual Priorities, Samuel C. Jutzi, J C. Tothhill

IGC Proceedings (1977-2023)

A review of animal feed research reports from 7 countries of eastern and southern Africa is used to assess historical and actual research emphases. Priority was on feed supply and evaluation for cattle production with strong rangelands improvement programmes. Most research focused on ecologically favoured regions and larger-scale livestock commodity production. Strong efforts for the exploitation of grasses for improved feed supply were supported by legume work for feed quality improvement. There was a strong emphasis on feed agronomy work, one third of all that work involving animals. Component research results were reported with little discussion of target systems implications, …

Animal Production And Dynamics Of Pangola Grass, Ryegrass, And White Clover As Influenced By Grazing Pressure, A De Moraes, G E. Maraschin

IGC Proceedings (1977-2023)

A grazing experiment was conducted at the Estacao Experimental Agronomica - UFRGS, Eldorado do Sul, RS, from June 1989 to March 1990, to evaluate a mixed pasture of pangola grass (Digitaria eriantha), ryegrass (Lolium multiflorum) and white clover (Trifolium repens) under 4 levels of grazing pressure (GP), namely: 3.S, 7 ,0, 10.5 and 14.0 kg DM of forage on offer /100 kg live weight (LW), with 2 field replications. Average live-weight gain (LWG) decreased as grazing pressure increased. Maximum LWG was obtained at grazing pressures of approximately 12%, which was associated with DM residues …

Cultivated Pasture, Forage On Offer And Animal Responseg, G E. Maraschin, A De Moraes, L.F. A. Da Silva, J Riboldi

IGC Proceedings (1977-2023)

Animal gains on pasture are influenced by the forage dry mailer on offer (DMO). To ascertain this relationship a pangola grass (Digitaria eriantha) pasture was evaluated under forage DMO levels of 3.5%, 7.0%, 10.5% and 14.0% of live weight (LW)/head/day. Two steers were assigned to each treatment as tester animals plus a number of put-and­take steers to maintain the desired levels of forage DMO, at the Estacao Experimental Agronomica • UFRGS • 30°S, from November 1989 to March 1990 (period I) and from October 1990 to May 1991 (period II). Pasture DM production and crude protein were not …

Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares

IGC Proceedings (1977-2023)

Extensive cattle production systems in north-east Argentina are based on the use of native pastures. One of the most important limiting factors to improve production is the acute phosphorus deficiency of soils and pastures. A large experiment was set up to study the effect of phosphorus fertiliser and mineral supplementation on the live­weight gain of steers of 2 ages grazing native pastures. Supplementation with a mixture of bone meal and salt, residual effect of P fertilisation, and both treatments applied together increased the annual animal live-weight gain by 60, 66 and 106%, respectively. The response of younger steers to fertiliser …

Ending Arbitrary Invasions By Shielding "Abandoned" Password Protected Phones, Samuel Chan

Florida Law Review

Almost every American carries a cell phone in their pocket. But modern phones do much more than simply send and receive calls. Cell phones in the twenty-first century contain a digital record of one’s entire life. The wealth of private information that can be gathered from a cell phone has led the Supreme Court to recognize the need for increased digital data protections. In Riley v. California, the Court recognized the privacy concerns associated with modern cell phones and curtailed warrantless searches of a phone incident to arrest. In Carpenter v. United States, the Court acknowledged smartphones can …

Imperfect Insanity And Diminished Responsibility, E. Lea Johnston

Florida Law Review

Insanity’s status as an all-or-nothing excuse results in the disproportionate punishment of individuals whose mental disorders significantly impaired, but did not obliterate, their capacities for criminal responsibility. Prohibiting the trier of fact from considering impairment that does not meet the narrow definition of insanity contradicts commonly held intuitions about mental abnormality and gradations of responsibility. It results in systemic over-punishment, juror frustration, and, at times, arbitrary verdicts as triers of fact attempt to better apportion liability to blameworthiness. This Article proposes a generic partial excuse: Diminished Responsibility from Mental Disability. This excuse could be asserted as an affirmative defense at …

Under The Bay: Analysis Of Green Sea Turtle (Chelonia Mydas) Dive Behavior In The Urban San Diego Bay, Emily Carter

Theses

Sea turtles are air-breathing marine reptiles that spend their lives performing dives to travel, forage, and rest. Several dive types have been previously recorded for sea turtles, each type being associated with a different set of behaviors. U-dives, or Type 1 dives are widely characterized by extensive benthic periods preceded by and concluding with abrupt descent and ascent phases respectively (Minamikawa et al. 1997; Houghton et al. 2002; Seminoff et al. 2006). These dives are widely affiliated with turtle resting behavior though can be indicative of additional activities including benthic travel and foraging. Previous research of green turtle dive behavior …

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan

Theses

In the eastern North Pacific, the oxygen minimum zone naturally shoals seasonally and impacts demersal fish habitat along the continental margins and on offshore seamounts. This hypoxic layer has been shoaling in recent decades, likely affecting the habitat and distribution of commercially-important fish species such as rockfishes (genus Sebastes). Respirometry and shuttle box behavioral experiments were used to determine the hypoxia sensitivities of two rockfish species with contrasting movement patterns and habitat use: cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis). Although both species inhabit similar deep-water, rocky-reef habitat, they have different lifestyles, in which cowcod …
