A Literature Review and Case Report Highlighting Pulmonary Artery Pseudoaneurysms Secondary to Uterine Leiomyosarcoma
Authors: Noff Nicole , Miller Daniel , Ilyas Usman , Hosna Asma , George Kevin , Balassiano Natalie
Published: June 2024

Pulmonary artery pseudoaneurysm (PAP) is a rare presentation of metastatic neoplasm. The mechanism of formation of PAP is thought to be due to tumor embolus penetration of the vessel wall and the formation of saccular dilation that is more prone to rupture than systemic arterial aneurysms. The leading cause of PAP is infection, and PAP related to neoplasm has rarely been reported. Early diagnosis and treatment are crucial as mortality associated with PAP rupture has been reported from 50-100%. CT pulmonary angiogram is the best approach for diagnosing PAP. Once the diagnosis is confirmed treatment depends on the etiology and clinical condition of the patient, but the favored first-line treatment is endovascular therapy.
The Practice of National Constitutional Courts Concerning Migration and Refugee Affairs – The Czech Republic
Authors: Otta Šimon
Published: June 2024

This article focuses on the relationship between the Czech Constitutional Court and European Union law, with an emphasis on asylum and migration policies. After introducing the Czech Constitutional Court, the article focuses on its relevant case laws in relation to European Union law and the transfer of powers from the Czech Republic to the Community institutions. Thereafter, it explores whether the Czech Constitutional Court perceives asylum and migration issues as part of the Czech constitutional identity, which the European Community must not interfere with, and presents the basic legal framework within which the Constitutional Court considers these issues. Finally, it examines the comparative method of interpretation in the case law of the Constitutional Court, supplemented by extensive citations of relevant decisions of the Constitutional Court.
PR-186-224500-R01 Assessment of Non-Welded Pipeline Repair Methods to Reduce Pipeline Blowdowns
Authors: Gould Melissa , Bruce Bill , Alexander Chris , Rosenfeld Michael
Published: June 2024

Non-welded repairs, such as fiber-reinforced composite systems and clamps with elastomer seals, may degrade over the life of the pipeline. As pipelines get older, it is important to evaluate the available repair options, and those currently installed, for continued service. This project explored the degradation associated with these non-welded repairs and provides practical guidance on how to assess, limit, or extend their service life. This will facilitate a reduction in Greenhouse Gas (GHG) emissions from a potential leak of a non-welded/temporary repair, allowing operators to either plan for their replacement with a permanent in-service repair or justify their continued use without arbitrary replacement.

This research was a recommended next step following PRCI Project MATR-3-15, Methods to Reduce Pipeline Blowdowns to Effectuate Repairs and Inspections. It is a precursor to MATR-3-15B, which is expected to conclude in 2025.

Sedimentary basins, hydrocarbons, graphite, coal, and Cu-Au deposits - from Mongolia to the Pacific margin: Interplay between the ubiquitous orthogonal fracture network and Global Wrench Tectonics
Authors: Storetvedt Karsten M. , Michaelsen Per
Published: June 2024

Mongolia is exceptionally rich in coal and copper-gold resources - with world-class deposits like Tavan Tolgoi, Oyu Tolgoi and Erdenet. Thus, the mining industry has a crucial importance for the national economy, yet most of the country remain very underexplored. Within today's global tectonics, an acceptable understanding of metal enrichments - including leaching, the internal hydrostatic-hydraulic pumping system, and surface emplacement mechanisms - has remained unresolved. However, a broader view of the structural situation in the Mongolia-China region shows a close link between orientation of elongate sedimentary basins, important mineral belts, and the fundamental orthogonal fracture/fault system. In the east the tectonic trend is dominantly northeast, while it is northwest in western areas. The main east Mongolian graphite deposits have northeast structural trends like numerous regional Cu and Au belts. A new theory of the earth, Global Wrench Tectonics, offers an exciting approach to better understanding the various facets of Earth's geological history and its surface resources. Earth’s degassing, dynamo-tectonic consequences, inertia-driven crustal wrench tectonics, as well as surface products such as water, hydrocarbons and ore deposits are given a coherent system explanation. Many hydrocarbons are products from the interior of our slowly degassing Earth, with massive hydrocarbon fields such as Songliao and the Yamal megaproject producing from the basement. Crustal thinning in the Songliao region is about the same as in southeast Mongolia, suggesting that they may have had similar degassing and crustal evolution histories. As such, it is not unlikely that the underexplored Mesozoic basins of southeast Mongolia - particularly at the deepest levels and/or in the adjacent crystalline basement - may have important hydrocarbon potential.

ORTHOGRAPHIC REGIONALISMS IN THE TRANSLATION OF EPITOMIES MADE BY EPIPHANIUS SLAVINETSKY
Authors: IVANOVA E.V.
Published: June 2024

The article deals with some orthographic regionalisms in the translation of Epitomii made by Epiphanius Slavinetsky from Greek in the second half of the 17th century. The paper compares the draft-autograph of Epiphanius Slavinetsky, which has not been previously analysed, and the clean list. On this material it is shown that not all such elements were eliminated by the editors. Some of them, taking into account the changing linguistic comprehension at different stages of the work, could be intentionally preserved (the change of ѣ to и), while others (the writing of s after r, the mixing of ‘ige’ and ‘era’) were subjected to editing. The description of these peculiarities makes it possible not only through the handwriting, but also through the language itself to attribute the draft to E. Slavinetsky, taking into account the comparison of the material with the scribe’s idiolect.
PUSHKIN AND FENELON:
TO THE STATEMENT OF THE PROBLEM
Authors: Ivinskiy Dmitriy P.
Published: June 2024

The article characterizes Pushkin’s attitude to Fenelon, including his
reviews of the French author, facts testifying to his interest in the editions of Fenelon’s works available to him, Pushkin’s poetic impromptu “The Boring role of
Telemachus...” (1824), which allows us to discuss not only some biographical facts
reflecting Pushkin’s stay in the south of Russia, but also his worldview, correlated
with the “spirit of the era” and reflected in a number of works. The problem of
identifying hidden quotations from Fenelon’s works in the works of the Russian poet
is considered to be of secondary importance, and the most significant is the complexly organized sphere of reflected influences on the literary and ideological space
of the Pushkin era, in which poets and thinkers of the past were irrevocably present
as those who set the religious, philosophical and ideological “agenda”. An important
element of this space was the spiritual heritage of Quietism, interest in which persisted throughout the 18th century, especially in the Masonic environment, and
intensified in the 1810s. In parallel to the Quietist doctrine of the possible descent
of grace into a soul that has renounced the world and itself, its own inescapable
sinfulness without favor from above, Pushkin created the contours of his concept of
poetic creativity, which was based on the theme of the “divine word”, which “touched”
someone who “dragged” in spiritual devastation “the gloomy Desert” (“The Prophet”, 1826), combined with the theme of silence (“Conversation of a Bookseller with
a Poet”, 1824) and a number of other motifs, including those related to the poetry of
V.A. Zhukovsky, who relied, in particular, on Fenelon and the Quietism.
CHOICE OF THE FORM OF TAXATION OF A MICRO-ENTERPRISE AS AN INSTRUMENT OF TAX OPTIMILISATION IN THE LIGHT OF THE CHANGES IN THE POLISH DEAL
Authors: Florek Joanna
Published: June 2024

The purpose of this article is an evaluation of the impact of changes in regulations concerning income tax assessment and premiums for medical insurance from economic activity of microenterprises as part of the so-called „Polish Deal” on the value of regulatory liabilities arising from income tax and health contribution in context of various forms of taxations. Ambiguity and changeability of the regulations as well as an increase in regulatory liabilities is not helpful to entrepreneurs in business development and constitutes obstacles, hindering the advancement of the microenterprise sector. Choosing the taxation form of conducted business is very significant for the amount of income tax expense of microenterprise. Amendments to tax regulations due to the 2022 introduction of the „Polish Deal” caused a revolution in forms of accounting for income tax and regulations defining the value of premiums for medical insurance in microenterprise groups. It results from the conducted research that implementing regulations of the „Polish Deal” caused the increase of the regulatory liabilities for microenterprises which in turn in some cases result in a drop in profitability of conducted activity that can hinder entrepreneurship and lead to abandonment of conducting economic activity.
RELATIONSHIP OF THE SCALE OF INVESTMENT AND CHANGE IN FIXED ASSETS ON FARMS IN THE WIELKOPOLSKA PROVINCE
Authors: Czubak Wawrzyniec
Published: June 2024

The operation and development of any economic entity require the implementation of investments. In the case of farms in Poland, characterized by inadequate capital and structural problems, it is particularly necessary to undertake investment activities to modernize the farms. The main purpose of the study was to evaluate agricultural investments made on farms in the Wielkopolska Voivodeship. The analysis is based on unpublished data of the individual results registered in the Polish FADN for the farms which continuously participated in the system of agricultural accounting from 2009 to 2021. Measuring the scale of investments, the comprehensiveness of the implemented investments was determined by relating the sum of investment expenditures to the average annual size of fixed assets (reduced by the value of land). The results confirm that the initial level of farm resources strongly impact the capacity for development. The size of the farm, measured by the area of utilised agriculture area, determines the incurring of an appropriate and relatively stable amount of investment in subsequent years of operation. The results of the study indicate that not only the implementation of investments in general but also their scale (in relation to the value of assets) determines the development capabilities of farms and, therefore, the improvement of the farms’ resources.
IDENTIFICATION OF DIFFERENCES IN THE SOCIO-DEMOGRAPHIC CHARACTERISTICS OF FARMS PARTICIPATING AND NOT ARTICIPATING IN SHORT FOOD SUPPLY CHAINS. EMPIRICAL STUDY IN POLAND
Authors: Smędzik-Ambroży Katarzyna , Sapa Agnieszka , Borychowski Michał , Stępień Sebastian
Published: June 2024

The main aim of the research was to identify the differences in socio-demographic characteristics between managers of small farms in Poland who do and do not participate in short food supply chains (SFSCs). The analysis was based on the results of a survey conducted in 2023 among 199 respondents – farmers in Poland. Selected social and demographic variables were analysed. For the demographic ones, there were used: gender, age, education of the farm manager, and number of members on the farm. In turn, the level of social capital characterising farmers was described by participation in continuing education, participation in organizations, cooperatives, associations, clubs, etc., and participation in events, concerts, festivals, etc. A chi-square Pearson’s test of independence was used to compare two groups of farms in terms of the analysed variables. The strength of the relationships was measured using the V-Cramer convergence coefficient. Research revealed that among the social and demographic variables, gender and education were significant. Hence, among farms participating in the SFSCs, there were significantly more farms owned and managed by women and managers of those farms were better educated than managers of farms not participating in the SFSCs. Moreover higher level of social capital, particularly perceived through the involvement of farm owners or members of a household in lifelong education and membership in organisations, cooperatives, or associations was also a distinguishing feature of farms participating in the SFSCs.

Published: June 2024

Work related stress is a genuine and developing issue in the present world. Many employees, especially health workers in the world are witnessing an alarming increase in job stress. This was further worsened with the advent of the novel COVID 19 which put health workers in difficult and highly demanding work environments, and this negative effect of job stress on employee performance necessitated the need for this study. This study examined the effect of four job stress factors on employee performance, and how entrapment mediate the relationship between job stress and employee performance among health workers in government hospitals in Jos, Plateau State. The study adopted survey research method. A representative sample size of 341 health workers was used for this study, out of which three hundred and four (304) copies of the questionnaire were retrieved for analysis. Multiple regression model was employed to test the hypothesized relationships using SPSS. The result revealed that work overload, role conflict and harassment had significant and negative effects on employee performance. The study also showed that the relationship between peer competition and employee performance was not significant, and finally hypothesis five shows that entrapment mediates the relationship between job stress and employee performance. It was therefore recommended among others that Healthcare managers should employ management intervention programmes that would promote both the work place and the individual’s coping strategies. Specific job resources such as autonomy, job control, empowerment, organizational support, and access to information should be enhanced in other for healthcare professionals to deal with high job demands. Healthy competition should be encouraged among health workers in order to improve their effectiveness at work, and finally; Management should find a way of repressing dangerous competitive drive among employees in the workplace by providing an equal platform for all employees to thrive in their careers.
Annualised probabilities of pit slope failures using two methods
Authors: Contreras Luis Fernando , Oboni Franco , Oboni Cesar
Published: June 2024

A novel framework for assessing the annualised probabilities of slope failures in open-pit mining is presented by integrating traditional geomechanical models with a comprehensive semi-quantitative assessment of multiple sources of information available for the pit design. The methodology is developed through a comparative analysis of two distinct methods applied to a real-world case study, allowing for a deeper understanding of slope failure probabilities and their implications for risk management. The paper emphasizes the importance of moving beyond conventional adimensional probability of failure (APoF) definitions to estimate annualised probability of failure (PoF) values. A novel quantitative methodology is introduced to estimate the annual PoF of slopes based on geomechanical values, incorporating considerations of slope lifespan and factor of safety (FoS). Additionally, ORE2_Slopes is presented as an alternative semi-quantitative probabilistic evaluation method, and its estimates are compared with literature benchmarks and real-life pit experiences. The study highlights the significance of estimating annualised PoFs for quantitative risk assessment (QRA), considering various parameters such as time dependency, human factors, and monitoring for a comprehensive risk evaluation. The methodology aims to provide a unified framework that balances geomechanical considerations with expert judgement assessments, offering practical tools for informed decision-making in open pit designs.

Published: June 2024

This study assesses the effectiveness of online learning platforms in promoting inclusive education for students with disabilities. Utilizing a mixed-methods approach, the research combines quantitative data from surveys with qualitative insights from interviews and document analysis. The findings indicate that platforms with comprehensive accessibility features and Universal Design for Learning (UDL) principles significantly enhance educational outcomes and satisfaction for students with disabilities. However, disparities in satisfaction among different disability groups highlight the need for more tailored accommodations. Key themes identified include accessibility, usability, support, engagement, and persistent challenges. The study concludes that while online learning platforms have made significant strides, continuous improvement and stakeholder collaboration are essential for optimizing inclusivity and educational equity.
Third Stage Seed-Cotton Cleaning System Particulate Emission Factors for Cotton Gins: Particle Size Distribution Characteristics
Authors: Buser Michael , Whitelock Derek , Boykin Clif , Holt Gregory
Published: June 2024

This report is part of a project to characterize cotton gin emissions from the standpoint of total particulate stack sampling and particle size analyses. In 2006 and again in 2013, the United States (U.S.) Environmental Protection Agency (EPA) published a more stringent National Ambient Air Quality Standard for particulate matter with nominal diameter less than or equal to 2.5 µm (PM2.5). This created an urgent need to collect additional cotton gin emissions data to address current regulatory issues, because EPA AP-42 cotton gin PM2.5 emission factors were limited. In addition, current EPA AP-42 emission factor quality ratings for cotton gin PM10 (particulate matter with nominal diameter less than or equal to 10 µm) data are questionable, being extremely low. The objective of this study was to characterize particulate emissions for 3rd stage seed-cotton cleaning systems from cotton gins across the cotton belt based on particle size distribution analysis of total particulate samples from EPA-approved stack sampling methods. Average measured PM2.5, PM6, and PM10 emission factors based on the mass and particle size analyses of EPA Method 17 total particulate filter and wash samples from two gins (5 total test runs) were 0.00090 kg/227-kg bale (0.0020 lb/500-lb bale), 0.0075 kg/bale (0.017 lb/bale), and 0.012 kg/bale (0.027 lb/bale), respectively. The 3rd stage seed-cotton cleaning system particle size distributions were characterized by an average mass median diameter of 9.6 µm (aerodynamic equivalent diameter). Based on system average emission factors, the ratio of PM2.5 to total particulate was 3.84%, PM6 to total particulate was 32.2%, and PM10 to total particulate was 51.5%.
Sequential and Co-Application of Glyphosate and Glufosinate in Cotton
Authors: Cahoon Charles , York Alan , Jordan David , Seagroves Richard , Everman Wesley , Jennings Katie
Published: June 2024

Glufosinate controls GR Palmer amaranth (Amaranthus palmeri S. Wats.), but might be less effective than glyphosate on certain weeds. Glyphosate and glufosinate applications in tolerant cotton (Gossypium hirsutum L.) cultivars can broaden the spectrum of control and aid in resistance management. Research investigating sequential application and potential interactions with co-applications of glyphosate and glufosinate is limited. Field research at six locations evaluated Palmer amaranth and annual grass control with glyphosate and glufosinate co-applied or sequentially applied. Herbicides were applied to two-leaf cotton and repeated 14 d later. A GR biotype comprised 10 to 90% of the Palmer amaranth populations. Greater Palmer amaranth control was achieved following sequential applications of glufosinate compared with glyphosate. Co-application of glufosinate plus glyphosate was more effective than glyphosate alone at most locations but never more effective than glufosinate alone. Glyphosate controlled goosegrass (Eleusine indica [L.] Gaertn.) more than glufosinate and a similar response was observed for large crabgrass (Digitaria sanguinalis [L.] Scop.). Glufosinate and glyphosate co-applied were less effective than glyphosate alone on both grasses, but not more effective than glufosinate alone. Glufosinate followed by (fb) glyphosate was the preferred order for sequential application to control Palmer amaranth at most locations. With high percentages of the GR biotype, glufosinate applied sequentially was more effective than any other sequential applications. Glyphosate fb glufosinate and glufosinate fb glyphosate controlled large crabgrass similar to glyphosate applied sequentially and greater than glufosinate applied sequentially. For goosegrass, glyphosate fb glufosinate was more effective than the reverse. Seven days after the second postemergence application, sequential application of glyphosate fb glufosinate controlled goosegrass as well as glyphosate applied sequentially and better than glufosinate applied sequentially.
Evaluation of Cotton Cultivars and Breeding Lines for Tolerance to Monosodium Methanearsonate (MSMA) Under Field Conditions
Authors: Zhang Jinfa , Abdelraheem Abdelraheem , Zhu Yi , Whitelock Derek
Published: June 2024

Monosodium methanearsonate (MSMA) is an organic arsenical herbicide used to control weeds such as grasses and nutsedges in Upland cotton (Gossypium hirsutum) production. Transient crop injury, yield reduction, and maturity delays have been observed in commercial Upland cotton. It is unknown if genetic variation in MSMA tolerance in cotton exists. In this field study, seven replicated tests were conducted in the same field to compare MSMA tolerance among 212 commercial cotton cultivars and advanced breeding lines. The tests were sprayed over the top at the 4-true-leaf stage, and seedlings were assessed for crop injury severity on a scale of 0 (no injury) to 5 (death). Significant genotypic variation in MSMA tolerance was detected in three tests, and broad-sense heritability estimates for MSMA tolerance ranged from 0.476 to 0.846 with a mean of 0.712, indicating that most phenotypic variation in MSMA tolerance is heritable. Nine tested G. barbadense genotypes, including seven commercial Pima cultivars and two Sea-Island cotton lines, exhibited minimal crop injury with severity ratings of 0.40 to 0.83 (except for one cultivar with 1.33). Among the remaining 203 Upland cotton genotypes with crop injury ratings ranging from 0.90 to 3.67, five commercial transgenic cultivars and 38 public breeding lines exhibited various levels of MSMA tolerance. The results represent the first study in germplasm evaluation for MSMA tolerance and identify a set of tolerant cotton genotypes that can be selected in cotton production or used to develop new cultivars for commercial cotton production.

The 1st stage lint cleaning system particle size distributions were characterized by an average mass median diameter of 29.2 µm (aerodynamic equivalent diameter). Based on system average emission factors, the ratio of PM2.5 to total particulate was 1.39%, PM6 to total particulate was 11.1%, and PM10 to total particulate was 20.2%.
Evaluating Cotton Utilization in Nonwoven Textiles
Authors: Luitel Kishor Prasad , Hudson Darren , Ethridge Dean
Published: June 2024

Fabrics made from weaving and knitting yarns constitute the largest part of textiles manufactured around the world, but various nonwoven technologies constitute the fastest growing sector of textiles. This study evaluates the potential for cotton fiber in nonwoven textiles and analyzes the issues of cotton use in nonwovens, with a focus on potential target markets. Data were collected through an online survey conducted among the global companies producing nonwoven products. Cotton is not being used by most nonwoven producing firms. Polypropylene and rayon are the primary substitute fibers. Reasons for using the substitute fibers include price, price volatility, and processing costs of cotton. The willingness to use more cotton is evident for products requiring absorbency and especially in products for personal hygiene. The factors constraining cotton consumption in nonwovens are primarily economic in nature rather than technological.

Average measured PM2.5, PM6, and PM10 emission factors based on the mass and particle size analyses of EPA Method 17 total particulate filter and wash samples from three gins (9 total test runs) were 0.0032 kg/227-kg bale (0.0070 lb/500-lb bale), 0.032 kg/bale (0.071 lb/bale), and 0.060 kg/bale (0.131 lb/bale), respectively. The combined lint cleaning system particle size distributions were characterized by an average mass median diameter of 19.9 µm (aerodynamic equivalent diameter). Based on system average emission factors, the ratio of PM2.5 to total particulate was 1.50%, PM6 to total particulate was 15.3%, and PM10 to total particulate was 28.2%.

This report is part of a project to characterize cotton gin emissions from the standpoint of total particulate stack sampling and particle size analyses. In 2006 and again in 2013, the United States (U.S.) Environmental Protection Agency (EPA) published a more stringent National Ambient Air Quality Standard for particulate matter with nominal diameter less than or equal to 2.5 µm (PM2.5). This created an urgent need to collect additional cotton gin emissions data to address current regulatory issues, because EPA AP-42 cotton gin PM2.5 emission factors were limited. In addition, current EPA AP-42 did not include PM10 (particulate matter with nominal diameter less than or equal to 10 µm) and total particulate emission factors for mote cyclone robber systems. The objective of this study was to characterize particulate emissions for mote cyclone robber systems from cotton gins across the cotton belt based on particle size distribution analysis of total particulate samples from EPA-approved stack sampling methods. Average measured PM2.5, PM6, and PM10 emission factors based on the mass and particle size analyses of EPA Method 17 total particulate filter and wash samples from three gins (9 total test runs) were 0.0011 kg/227-kg bale (0.0024 lb/500-lb bale), 0.0085 kg/bale (0.019 lb/bale), and 0.015 kg/bale (0.032 lb/bale), respectively. The mote cyclone robber system particle size distributions were characterized by an average mass median diameter of 21.2 µm (aerodynamic equivalent diameter). Based on system average emission factors, the ratio of PM2.5 to total particulate was 2.20%, PM6 to total particulate was 16.9%, and PM10 to total particulate was 29.0%.

There has been renewed interest in using fluridone herbicide to aid in control of glyphosate-resistant Palmer amaranth (Amaranthus palmeri S. Watson) in cotton (Gossypium hirsutum L.). Section 18 Emergency Use Exemptions for fluridone in cotton have been granted recently in several states and the manufacturer is pursuing federal registration. Fluridone has long persistence in soil, leading to questions about rotational crop response. Field experiments were conducted in North Carolina to evaluate the potential for fluridone to carry over to corn (Zea mays L.), peanut (Arachis hypogaea L.), grain sorghum [Sorghum bicolor (L.) Moench.], and soybean [Glycine max (L.) Merr.] grown in rotation with fluridone-treated cotton. Fluridone at 0, 280, 420, 560, 840, and 1120 g ai ha-1 was applied preemergence to cotton and rotational crops were planted the following spring. The fluridone rates were well above proposed use rates. Only minor visible injury to cotton was observed and cotton yield was unaffected by fluridone. Fluridone also caused only minor visible injury to rotational crops and did not affect stands, early season height, or yield of rotational crops.

This created an urgent need to collect additional cotton gin emissions data to address current regulatory issues, because EPA AP-42 cotton gin PM2.5 (particulate matter with nominal diameter less than or equal to 2.5 µm) and PM10 (particulate matter with nominal diameter less than or equal to 10 µm) emission factors did not exist for mote cleaner systems. The objective of this study was to characterize particulate emissions for mote cleaner systems from cotton gins across the cotton belt based on particle size distribution analysis of total particulate samples from EPA-approved stack sampling methods. Two gins with mote cleaner systems were sampled. The exhaust from one of the mote cleaner systems was combined with the module feeder dust system. The average PSD based PM2.5, PM6, and PM10 emission factors for the mote cleaner system that was not combined with another cotton gin system were 0.0016 kg/227-kg bale (0.0036 lb/500-lb bale), 0.018 kg/bale (0.040 lb/bale), and 0.033 kg/bale (0.074 lb/bale), respectively. The PSD was characterized by an average MMD of 17.1 µm AED. The ratio of PM2.5 to total particulate was 1.53%, PM6 to total was 17.1%, and PM10 to total was 31.8%. The average PSD based PM2.5, PM6, and PM10 emission factors for the mote cleaner system that was combined with module feeder dust system were 0.00092 kg/227-kg bale (0.0020 lb/500-lb bale), 0.011 kg/bale (0.024 lb/bale), and 0.022 kg/bale (0.048 lb/bale), respectively. The PSD was characterized by an average MMD of 26.7 µm AED. The ratio of PM2.5 to total particulate was 0.85%, PM6 to total was 9.9%, and PM10 to total was 20.0%.

Cotton is a vital component of the economies of Mid-South states. Producers and landowners are looking for ways to reduce the variability of irrigated yields, and soil apparent electrical conductivity (ECa) is a readily obtained parameter that can indicate soil variability. A study was conducted in 2011 and 2012 at the Fisher Delta Research Center in Portageville, MO, with the objective to determine the impact of soil spatial variability on yield and irrigation water use efficiency for cotton. Observed ECa values were low, consistent with average sand contents that ranged from 59 to 82% in the upper 0.76 m of the soil profile. Spatial autocorrelation was present in the data and thus spatial analyses were used. In 2011, yields for two treatments were not significantly different from the mean field effect; however, the ECa effect was significant, indicating that soil variability impacted yield more than irrigation differences for the two treatments. In 2012, yields for four of the six treatments were significantly different from the mean field effect; however, the ECa effect was not significant. A quadratic equation was fit to the combined data from irrigated and rainfed plots in 2012. The resulting equation had a maximum of 3,372 kg ha-1 at 135 mm total irrigation and the median observed ECa value (3.0 mS m-1). Future efforts will include additional fields and environments, which should increase the understanding of the impact of soil variability and allow for improved selection of optimum management zones for site specific application of water and other inputs.

The objective of this study was to evaluate the association between Temperature and Humidity Index (THI), age, and post-collection time with post-thawing sperm cell parameters such as progressive motility, viability, morphology, and cytoplasmic droplets. Samples were collected from 4 male white-tailed deer after regulated hunting. THI was calculated on collection days. Two THI categories were determined, ≥70 and <70. Thawed semen was placed on a slide and observed under a phase-contrast microscope to evaluate the progressively motile sperm cells. Morphology, viability, and cytoplasmic droplets were assessed on a smear stained with eosin-nigrosine and classified as normal or abnormal, viable or not viable, and present or absent, respectively. When THI was ≥70, the progressive motility (51.0 vs 30.67%), sperm viability (51.0 vs 36.33%), and the proportion of sperm cells with normal morphology (65.0 vs 37.67%) were higher than to days with a THI <70, without differences in the presence of cytoplasmic droplets. The 4-years bucks had a higher proportion of sperm cells with normal morphology (81.0 vs 35.5 and 26.0%) and cytoplasmic droplets (27.0 vs. 12.0 and 7.5%) compared to 2- and 3-year-old animals. Samples processed after 4 hours (51.0%) had a higher progressive motility than samples processed after 6 and 8 hours (32.0 and 25.0%, respectively). Spermatozoa processed after 8 hours (30.0%) had a lower viability than spermatozoa processed after 4 hours (51.0%). Compared to samples processed after 6 and 8 hours, those processed after 2 and 4 hours had a higher proportion of sperm cells with normal morphology (26.0 and 6.0 vs 81.0 and 65.0%, respectively). Samples processed after 2 hours had a higher (27.0 vs. 12.0%) proportion of sperm cells with cytoplasmic droplets than to those processed after 6 hours. High THI favors progressive motility and sperm viability. The older bucks had a greater proportion of sperm cells with normal morphology and cytoplasmic droplets than to the young ones. The greater progressive motility, viability, morphology, and presence of cytoplasmic droplets were found when the samples were processed within the first 4 hours.
