Evaluation Of Different Nitrogen Sources On The Production And Chemical Properties Of C4-Sub-Tropic Pastures, J F. Reckling, G.H J. Kruger

IGC Proceedings (1977-2023)

Digitaria eriantha fertilised with limestone ammonium nitrate (LAN 28 % N), although not statistically significant, resulted in higher dry matter production in comparison to those plants fertilised with urea (U 46% N). Significant lower (P<0.05) soil calcium levels were found in plots fertilised with LAN. Plants fertilised with urea had double the amount of Aspartic and Glutamic acid, indicating that urea did not convert to NO3 -, but was taken up as ammonium.

IGC Proceedings (1977-2023)

The effect of nitrogen and potash fertilizations on dry matter and protein yields and chemical composition of pangolagrass (D. decumbens Stent.) was studied in a randomized block design with four replications using a 2 x 2 factorial arrangement. Nitrogen and potash were applied after each cut as an equivalent to 3 and 2% of dry matter (65°C) yield, respectively. There were great increases in dry matter and protein yields when nitrogen alone or combined with potash was used. Potash fertilization alone had no effect on the variables described above. Nitrogen fertilization improved forage pangolagrass composition, being particularly effective on crude …

Nitrogen In Stubble As A Limiting Factor Of Regrowth And Yield Of Orchardgrass After Cutting, T Matsunaka, T Ishii, M Jin

IGC Proceedings (1977-2023)

Two field trials were carried out to reexamine the role of total nonstructural carbohydrates (TNC) and nitrogen (N) of the stubble in regrowth of orchardgrass (Dactylis Glomerata L.) during 10 days after cutting and the yield of next cutting. The regrowth and the yield were independent of TNC content in the stubble. They increased with N content in the stubble derived from the different rate of previous N application. When the TNC content in the stubble at the time of cutting was more than about 18% (dry matter basis), the regrowth even in a darkroom was not affected by …

Grassland Management In Central Area Of The Masurian Landscape Park, K Mlynarczyk, E Marks, E Korona

IGC Proceedings (1977-2023)

Permanent grassland occupy some 12% of the area of the Masurian Landscape Park. The Cirsio-Polygonetum plant association was distinguished on the semi-natural meadows situated on the peat-marsh soil. Changes in botanical composition of the meadow sward and the productivity of DM, against a background of different mineral fertilization, were examined in a medium-scale plot experiment. It was concluded that both aspects ofutilization must be accorded high priority in the case of extensively managed meadows: medium level of forage production and the landscape conservation.

Impact Of Extensive Management On Demography Of One Invasive Species Of Permanent Grasslands, D Magda

IGC Proceedings (1977-2023)

The objective of this study is to show the effect of extensive practices on the population dynamics of a grassland species (Chaerophyllum aureum) in order to control invasion process. Fertilisation intensity (none or 45g/m2), number (none, one or two) and date of cutting (before or after seed maturity) have been experienced on permanent plots in fields to follow consequences on demography of adults and seedlings. Adult density is regulated through cutting effect and intraspecific competition process. Reduction of competition by cutting leads to a paradoxal highest adult survival rate in on cut treatment compared with abandoned invaded fields. …

Grassland Management For Geese: Sustainable Use For Conservation And Agriculture, S M. Percival, R Lilley Jun 2024

Grassland Management For Geese: Sustainable Use For Conservation And Agriculture, S M. Percival, R Lilley

IGC Proceedings (1977-2023)

Increasing numbers of overwintering wild geese have caused considerable problems to agriculture but are often also of conservation concern as their populations are relatively small. Islay, Scotland, is one site where this problem is particularly acute. We studied the two goose species which use this site, the barnacle goose, Branta leucopsis, and the white-fronted goose, Anser albifrons flavirostris, and found that they preferred younger pastures located closer to their roost sites. These preferred areas could be important in developing a sustainable strategy for future goose management. Further non-sustainable population increases might be avoided by increasing disturbance in these areas.

Potent And Selective Small Molecule Mcl-1 Inhibitor Demonstrates Anti-Myeloma Activity And Overcomes Chemotherapy Resistance, Omar Sami Faleh Al-Odat

Theses and Dissertations

Despite a record number of clinical studies investigating various anti-myeloma treatments, the 5-year survival rate for multiple myeloma (MM) patients in the US is only 55%, and nearly all patients relapse. Poor patient outcomes demonstrate that myeloma cells are "born to survive” which means they can adapt and evolve following treatment. Thus, new therapeutic approaches to combat survival mechanisms and target treatment resistance are required. Importantly, Mcl-1, anti-apoptotic protein, is required for the development of MM and treatment resistance. This study looks at the possibility of KS18, a selective Mcl-1 inhibitor, to treat MM and overcome resistance. Our investigation demonstrates …

Successful Management Of Chromoblastomycosis Utilizing Conventional Antifungal Agents And Imiquimod Therapy, Jinjin Zheng, Shougang Liu, Zhenmou Xie, Yangxia Chen, Liyan Xi, Hongfang Liu, Yinghui Liu

Faculty, Staff and Student Publications

Chromoblastomycosis (CBM), a chronic fungal infection affecting the skin and subcutaneous tissues, is predominantly caused by dematiaceous fungi in tropical and subtropical areas. Characteristically, CBM presents as plaques and nodules, often leading to scarring post-healing. Besides traditional diagnostic methods such as fungal microscopy, culture, and histopathology, dermatoscopy and reflectance confocal microscopy can aid in diagnosis. The treatment of CBM is an extended and protracted process. Imiquimod, acting as an immune response modifier, boosts the host's immune response against CBM, and controls scar hyperplasia, thereby reducing the treatment duration. We present a case of CBM in Guangdong with characteristic reflectance confocal …

Numerical Issues For A Non-Autonomous Logistic Model, Marina Mancuso, Kaitlyn M. Martinez, Carrie Manore, Fabio Milner

CODEE Journal

The user-friendly aspects of standardized, built-in numerical solvers in
computational software aid in the simulations of many problems solved using
differential equations. The tendency to trust output from built-in numerical
solvers may stem from their ease-of-use or the user’s unfamiliarity with the
inner workings of the numerical methods. Here, we show a case where the
most frequently used and trusted built-in numerical methods in Python’s
SciPy library produce incorrect, inconsistent, and even unstable approxima-
tions for a the non-autonomous logistic equation, which is used to model
biological phenomena across a variety of disciplines. Some of the most com-

Supplementary Files For "Using Digitized Building And Weather Records To Improve The Accuracy Of Ground To Roof Snow Load Ratio Estimations", Gideon Parry, Brennan Bean

Browse all Datasets

Reliability targeted snow loads (RTLs) measure the weight in accumulated snow (i.e. snow load) that a roof is required to support to ensure the probability of failure is suf- ficiently low. This calculation has historically relied upon a probability distribution that characterizes the ratio between the annual maximum ground snow load to the annual max- imum roof snow load, a quantity referred to as Gr. The best available data for estimating Gr comes from Canadian case studies from the 1950s and 1960s. However, much of the data was never digitized, with only approximations of data being made available in scanned …

Defect-Free Nanowelding Of Bilayer Snse Nanoplates, Jing-Rong Ji, John W. D. Villanova, Salvador Barraza-Lopez, Stuart S. P. Parkin, Kai Chang

Physics Faculty Publications and Presentations

Nanowelding is a bottom-up technique to create custom-designed nanostructures and devices beyond the precision of lithographic methods. Here, a new technique is reported based on anisotropic lubricity at the van der Waals interface between monolayer and bilayer SnSe nanoplates and a graphene substrate to achieve precise control of the crystal orientation and the interface during the welding process. As-grown SnSe monolayer and bilayer nanoplates are commensurate with graphene's armchair direction but lack commensuration along graphene's zigzag direction, resulting in a reduced friction along that direction and a rail-like, 1D movement that permits joining nanoplates with high precision. This way, molecular …

"Vampire Plastics": An Investigation Of Poly(Olefin Sulfone) Depolymerization And Its Dust Mitigation Abilities, Alexandra Kathryn Kanani Gallion Stapley

Theses and Dissertations

The ubiquity of particulate contamination requires dust mitigation techniques to provide low-scatter surfaces and edges on sensitive optical devices in space. Poly(olefin sulfone)s have been shown to photodegrade with the assistance of a photobase generator when exposed to UV light (254 nm) and heat (120 °C). These polymers may be useful for minimizing dust on optical surfaces for space applications. However, their behavior in vacuum has not been fully characterized. We synthesized poly(2-methyl-1-pentene sulfone) (PMPS) and poly(1-hexene sulfone) (PHS) with and without a photobase generator. We studied the photodegradation (172 nm or 254 nm) of thin films in vacuum. Spectroscopic …
