Seed Yield Potential Of White Clover: Characteristics, Components And Compromise, P.T P. Clifford, I J. Baird

IGC Proceedings (1977-2023)

Nd relationship between leaf size and any of the measured variables was found for 63 agronomically superior white clover (Trifolium repens L.) plants of relatively diverse morphological and physiological characteristics, Predominantly crown-flowering plants gave more than double the seed yield of stolon-lip 'flowerers. High seed yields were also associated with delays in peak flowering, harvest date and increased harvest dry matter. Similar associations were evident for inflorescence density. Increased dry matter accumulation was associated with increases in both floret numbers and seeds/ inflorescence.

Studies In Germination And Thousand-Seed Weight In Chicory Cv. Grasslands Puna, W J. Archie, J S. Rowarth, B R. Guy

IGC Proceedings (1977-2023)

A strong, positive correlation was found between 1000-seed weight (TSW) and germination in chicory (Cichorium intybus L.) cv. Grasslands Puna. Low TSW tended to be associated with empty or immature seed; empty seed was associated with exclusion of bees. No significant differences in seed characteristics were found between seeds harvested from different positions (top, middle or bottom third) on the plant. Optimum harvest lime was 4 weeks after peak flowering.

Seed Production Of Plantain (Plantago Lanceolata L.), J S. Rowarth, M P. Rolston, W J. Archie

IGC Proceedings (1977-2023)

Seed development studies showed that seed maturity in plantain (Plantago lanceolata L,) occurred 6 weeks after anthesis; maximum seed yields were obtained 8 weeks after anthesis. This is consistent with the fact that seed heads take approximately 17 days to complete flowering. Fertiliser nitrogen increased plantain seed yield. Time of closing, timing of nitrogen application and different stand densities did not significantly affect seed yield, probably because plantain can adapt to and compensate for the treatments imposed.

Reproductive Initiation, Closing Dates, Nitrogen Requirements And Harvesting Of Smooth Brome Cv. Grasslands Tiki, J S. Rowarth, W J. Archie

IGC Proceedings (1977-2023)

Reproductive initiation, closing dates, nitrogen requirements and optimum harvest time were investigated for seed production of Grasslands Tiki smooth brome (Bromus inermis Leyss.) in the South Island of New Zealand. Reproductive initiation began in late June, spikelet initiation in mid-September and ear-emergence in mid­October. Seed yield was not affected detrimentally by mowing to 5 cm in mid-September but decreased 24% by mowing in mid-October. Seed yield tended to increase with increasing amounts of N. However, although the highest seed yields were achieved with 50 kg/ha of N in autumn plus I 00 or 150 kg/ha in spring, they did not …

Evaluation Of Non-Thermal Residue-Removal Equipment Used By Willamette Valley Seed Growers As A Substitute For Open-Field Burning, William C. Young Iii, David O. Chilcote, Thomas B. Silberstein

IGC Proceedings (1977-2023)

Recent legislation reducing open-field burning in Oregon has caused many grass seed producers to experiment with non-thermal residue management alternatives. On-farm test sites were selected to evaluate 4 post-harvest residue removal treatments common at 7 locations. Seed yield did not differ significantly when residue management treatments were applied to new stands of perennial ryegrass (Lolium perenne) and tall fescue (Festuca arundinacea) after harvest of the first seed crop. Control of weeds and volunteer crop seedlings was poorest where increased amounts of crop residue remained on the soil surface.

Sowing Rate And Row Spacing In Pure Stand Establishment Of Smooth Meadowgrass For Seed Production, Trygve S. Aamlid

IGC Proceedings (1977-2023)

Seed production of smooth meadow grass (Poa pratensis L.) cv. Lavang was compared at 3 sowing rates (2.5, 5.0 and l0.0 kg/ha) and at 2 row spacings (16.5 and :n cm), the wider used in conjunction with carbon banding. Results varied between fields according to temperature after planting and the weed content of the soil, but, on average, 5.0 kg/ha proved to be the optimal sowing rate. 33 cm row spacing and carbon banding caused a higher proportion of tillers to develop panicles and gave a higher seed yield with a better weed control in the first and third …

Role Of Galega Seed In Forage Production, H Raig

IGC Proceedings (1977-2023)

The effects of different soil types and seeding rates and row spacing on the yield of galega (Galega orientalis) have been determined in long-term trials. Over 10 years al the Estonian Research Institute of Agriculture, IO00-seed weight was 6.7-8.4 g. Ten-yenr average seed yield (kg/hn) was 241, 305 nnd 424 on soils of pH 5.6, 6.0 and 6,3, respectively. Seed yields of galega were about 6 times those of alfalfa in the soil at pH 6.3. Seeding rate and now spacing hnd little effect on seed yields. In south Sakhalin, galega was winter-hardy at - 47°C and survived drought …

Effect Of Paclobutrazol On Seed Yield In The Subtropical Grass Digitaria Eriantha, L Ramirez, J B. Hacker

IGC Proceedings (1977-2023)

Lodging of Digitaria erlantha can reduce seed yield of well-fertilised seed crops. This experiment was designed to assess the effect of the growth retardant paclobutrazol on seed production and its components in a spring crop of D. erialllha cv. Premier. Paclobutrazol decreased lodging, reduced tiller height and weight and tended to increase seed set, seed weight and seeds per panicle. However, it also tended to reduce panicle density. Treatment with 0.75 kg ai/ha applied at initial panicle emergence was optimal, increasing pure seed yield from 305 to 462 kg/ha. Paclobutrazol has potential for increasing seed yield in D. erantlta through …

Seed Shattering In Tall Fescue, Mario Falcinelli

IGC Proceedings (1977-2023)

Seed shattering in many commercial grass seed crops is a serious problem which makes seed harvesting difficult and which is often a major cause of high losses in seed yield. 2880 plants of tall fescue (Festuca arundinacea) belonging to 48 natural populations collected at sites scattered from northern (46° 10'N) to southern (39°05'N) Italy and 60 plants of the cultivar Fawn were grown in Perugia (Italy) as spaced plants. Al peak anthcsis, 5 panicles from each plant were randomly chosen and 40 days later they were evaluated for seed retention capability. Ten plants, belonging to 9 different populations, …

Achieving Potential Herbage Seed Yields In Species Of Temperate Regions, Franco Lorenzetti

IGC Proceedings (1977-2023)

The potential seed yield (PSY) of a crop is represented by the total number of ovules present at anthesis in a unit area and is very high for nil forage species. However, seed yield or the agricultural realised seed potential (ARSP) is very low especially if compared with major grain crops (e.g., 15% vs 40% of PSY, respectively). The need for obtaining primarily high yield of high quality forage indicates that seed yield should be increased by improving the efficiency of the reproductive system rather than increasing its size. Seed setting and development and seed shattering are the characters to …

Disparity And The Need For Sentencing Guidelines In Maine: A Proposal For Enhanced Appellate Review, Daniel E. Wathen

Maine Law Review

Perhaps in no other field of judicial endeavor is diversity and variety more apparent than when a sentencing judge considers the circumstances presented by a defendant convicted of a criminal offense. In each case, the sentencing judge confronts an individual who has no exact counterpart in any defendant previously appearing before the court for sentencing. The sentence imposed is primarily a matter of judicial discretion and is based upon consideration of the nature of the offense, the circumstances surrounding the commission of the offense, and the circumstances of the defendant. The sentencing judge formulates a specific sentence within broad statutory …

A New Conceptual And Analytic Framework For Collective Engagement In Mathematics, Tye G. Campbell, Michael A. Lawson

Teacher Education and Leadership Faculty Publications

This paper proposes a new social construct and conceptual-analytic framework for the study of group engagement in mathematics, which we call collective engagement structures. This new framework is offered to address research and practice-identified needs to better understand how individual student dispositions and preferences might interact with group processes to inform student engagement and learning. We demonstrate the collective engagement structures framework using a case study analysis of three middle school students working in a group on a complex mathematics problem. Our analysis details how three students’ individual engagement structures and positional influence interact to form two collective engagement structures: …

Α4 Nicotinic Acetylcholine Receptors In Lipopolysaccharide-Related Lung Inflammation, J. Ritzenthaler, Walter H. Watson, Jesse Roman

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Sepsis remains an important healthcare challenge. The lungs are often affected in sepsis, resulting in acute lung injury characterized by inflammation. Mechanisms involving lipopolysaccharide (LPS) stimulation of toll-like receptor (TLR) signaling with induction of proinflammatory pathways have been implicated in this process. To date, however, studies targeting these pathways have failed to improve outcomes. We have found that LPS may also promote lung injury through the activation of α4 nicotinic acetylcholine receptors (α4 nAChRs) in immune cells. We observed increased expression of α4 nAChRs in human THP-1 monocytic cells exposed to LPS (100 ng/mL, 24 h). We also observed that …

Assessment Of Employee Risks In Construction Of Megahousing Projects Using Structural Equation Modeling, Mohamed Nabawy

Civil Engineering

One of the most crucial objectives for nations with dense populations worldwide is the construction of mega projects. Egypt's 2030 strategy emphasizes how crucial it is to build MHP in order to accommodate the country's enormous population growth. However, there has been a nighty eight percent delay in the completion of house construction projects due to employees' inadequate training, technology use, and uncertainty management. Enhancing the administrative, technical, and management skills of staff members can prevent delays in Egypt's delivery of sustainable MHP. The aim of this study is to develop an employee management model (ESEM) in order to assess …

Graph Regularized Sparse L2,1 Semi-Nonnegative Matrix Factorization For Data Reduction, Anthony Rhodes, Bin Jiang, Jenny Jiang

Mathematics and Statistics Faculty Publications and Presentations

Non-negative Matrix Factorization (NMF) is an effective algorithm for multivariate data analysis, including applications to feature selection, pattern recognition, and computer vision. Its variant, Semi-Nonnegative Matrix Factorization (SNF), extends the ability of NMF to render parts-based data representations to include mixed-sign data. Graph Regularized SNF builds upon this paradigm by adding a graph regularization term to preserve the local geometrical structure of the data space. Despite their successes, SNF-related algorithms to date still suffer from instability caused by the Frobenius norm due to the effects of outliers and noise. In this paper, we present a new L2,1 SNF algorithm that …

Local Hydroclimate Alters Interpretation Of Speleothem Δ18o Records, E. W. Patterson, V. Skiba, A. Wolf, M. L. Griffiths, D. Mcgee, T. N. Bùi, M. X. Trần, T. H. Đinh, Q. Đỗ-Trọng, Gregory R. Goldsmith, V. Ersek, K. R. Johnson

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Oxygen isotopes (δ¹⁸O) are the most commonly utilized speleothem proxy and have provided many foundational records of paleoclimate. Thus, understanding processes affecting speleothem δ¹⁸O is crucial. Yet, prior calcite precipitation (PCP), a process driven by local hydrology, is a widely ignored control of speleothem δ¹⁸O. Here we investigate the effects of PCP on a stalagmite δ¹⁸O record from central Vietnam, spanning 45 – 4 ka. We employ a geochemical model that utilizes speleothem Mg/Ca and cave monitoring data to correct the δ¹⁸O record for PCP effects. The resulting record …

Manifestations Of Sulfuric Acid Speleogenesis In The Mulapampa Travertine, Central Andes Of Peru: Evidence From The Gruta Con Lago, Andrzej Tyc, Krzysztof Gaidzik, Justyna Ciesielczuk, Katarzyna Wątor

International Journal of Speleology

Sulfuric acid speleogenesis (SAS) is a form of hypogene speleogenesis characterized by the formation of caves in carbonate rocks due to the presence of sulfuric acid. This study focuses on the Gruta con Lago, one of three caves identified in the Mulapampa travertine, located in the central Andes of Peru. These caves are accessed through collapse sinkholes, and much of their morphology results from roof breakdown. The bottom of the studied cave is situated at the current water table. Despite the absence of typical solutional features associated with SAS caves, mineralogical and geochemical evidence of speleogenesis involving H₂SO …

Multi-Agent Reinforcement Learning For Smart Community Energy Management, Patrick Wilk, Ning Wang, Jie Li

Henry M. Rowan College of Engineering Departmental Research

This paper investigates a Local Strategy-Driven Multi-Agent Deep Deterministic Policy Gradient (LSD-MADDPG) method for demand-side energy management systems (EMS) in smart communities. LSD-MADDPG modifies the conventional MADDPG framework by limiting data sharing during centralized training to only discretized strategic information. During execution, it relies solely on local information, eliminating post-training data exchange. This approach addresses critical challenges commonly faced by EMS solutions serving dynamic, increasing-scale communities, such as communication delays, single-point failures, scalability, and nonstationary environments. By leveraging and sharing only strategic information among agents, LSD-MADDPG optimizes decision-making while enhancing training efficiency and safeguarding data privacy—a critical concern in the …

Temporal Variations In And Predictive Values Of Abg Results Prior To In-Hospital Cardiac Arrest, Mina Attin, Jie Rin, Chad Cross, Sidath Kapukotuwa, Ryan Shao, Peter G. Kaufmann, C.D. (Joey) Lin, Kim Arcoleo

Nursing Faculty Research

In-hospital cardiac arrest (IHCA) has been understudied relative to out-of-hospital cardiac arrest. Further, studies of IHCA have mainly focused on a limited number of pre-arrest patient characteristics (e.g., demographics, number and types of comorbidities). Arterial blood gas (ABG) analysis, one of the most common diagnostic tests for assessing and managing critically or acutely ill hospitalized patients, reflects pathophysiological changes associated with adverse events or complications, including IHCA. Yet the predictive and prognostic values of patterns of pre-arrest ABG parameters for IHCA have not been fully studied. The purpose of this retrospective pilot cohort study was to investigate temporal variations in …
