Samuel Lowry Latimer, Jr. Papers - Accession 530

The personal papers of Samuel Lowry Latimer, Jr. (1891-1975) include insurance, financial and tax records, various state-related pamphlets, photographs (mainly from The State newspaper) and postcards, and galley proofs of Three Scores and Ten, a history of The State written by Mr. Latimer (published in 1970 under the title The Story of The State and the Gonzales Brothers, see appendix #2). Also included are items of personal and business correspondence of Mr. Latimer and Major McDavid Horton (1884-1941) (editor of The State from 1938 to 1941), various personal items and memorabilia from Mr. Latimer’s two trips abroad, newspaper clippings and articles relating to or published in The State, critiques of The Story of The State and the Gonzales Brothers done by Mrs. Albert D. (May) Oliphant, and several miscellaneous newspaper articles. One of the major subjects of the collection is founding of The State newspapers and the Gonzales Brothers. The Gonzales brothers are Narciso Gener Gonzales (1858-1903), Ambrose Elliott Gonzales (1857-1926), and William Gonzales (1866-1937) and the former two founded The State newspaper in Columbia, SC in 1891. Narciso would later be gunned down on January 15, 1903 (he died four days later) by James H. Tillman. James Tillman was Lieutenant Governor of South Carolina (and nephew of SC Senator Benjamin Tillman) and was a frequent target of criticism by the paper. Tillman would be acquitted by a jury despite many witnesses and received no punishment.https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/1623/thumbnail.jp

Nutritional Status and Infant and Young Child Feeding (IYCF) Practices among Buhid Mangyan Tribe, Occidental Mindoro Philippines

Nutritionally adequate and safe complementary feeding starting from the age of 6 months up to 59 months is one of the effective intervention to reduce infant and child morbidity and malnutrition. This study aims to determine the nutritional status of children ages 6-59 months and their caregiver’s infant and young child feeding (IYCF) practices of the Buhid community in Rizal, Occidental Mindoro. The design used in this study was a descriptive cross-sectional carried out between December 2016-February 2017. A survey questionnaire was utilized as an instrument in this study. It includes an anthropometric survey of 6-59 months old and infant and young child feeding practices using WHO and UNICEF IYCF indicators. Vaccination, vitamin A supplementation and deworming coverage were also measured. Findings revealed a prevalence of global acute malnutrition (GAM) at a critical level. There is a low but significant prevalence of stunting and underweight among children. There is a good infant and young feeding practice in the community except for the minimum acceptable diet during complementary feeding. Lastly, there is low BCG and measles vaccination coverage in the community that could be a threat to the impending disease outbreak

Principles of appropriate antibiotic use for treatment of uncomplicated acute bronchitis: background.

The following principles of appropriate antibiotic use for adults with acute bronchitis apply to immunocompetent adults without complicating comorbid conditions, such as chronic lung or heart disease. The evaluation of adults with an acute cough illness or a presumptive diagnosis of uncomplicated acute bronchitis should focus on ruling out serious illness, particularly pneumonia. In healthy, nonelderly adults, pneumonia is uncommon in the absence of vital sign abnormalities or asymmetrical lung sounds, and chest radiography is usually not indicated. In patients with cough lasting 3 weeks or longer, chest radiography may be warranted in the absence of other known causes. Routine antibiotic treatment of uncomplicated acute bronchitis is not recommended, regardless of duration of cough. If pertussis infection is suspected (an unusual circumstance), a diagnostic test should be performed and antimicrobial therapy initiated. Patient satisfaction with care for acute bronchitis depends most on physician--patient communication rather than on antibiotic treatment

4D, N = 1 Supersymmetry Genomics (I)

Presented in this paper the nature of the supersymmetrical representation theory behind 4D, N = 1 theories, as described by component fields, is investigated using the tools of Adinkras and Garden Algebras. A survey of familiar matter multiplets using these techniques reveals they are described by two fundamental valise Adinkras that are given the names of the cis-Valise (c-V) and the trans-Valise (t-V). A conjecture is made that all off-shell 4D, N = 1 component descriptions of supermultiplets are associated with two integers - the numbers of c-V and t-V Adinkras that occur in the representation.Comment: 53 pages, 19 figures, Report-II of SSTPRS 2008 Added another chapter for clarificatio

Methylrhenium Trioxide Revisited: Mechanisms for Nonredox Oxygen Insertion in an M−CH_3 Bond

Methylrhenium trioxide (MTO) has the rare ability to stoichiometrically generate methanol at room temperature with an external oxidant (H_2O_2) under basic conditions. In order to use this transformation as a model for nonredox oxidative C−O coupling, the mechanisms have been elucidated using density functional theory (DFT). Our studies show several possible reaction pathways to form methanol, with the lowest net barrier (ΔH‡) being 23.3 kcal mol^(-1). The rate-determining step is a direct “Baeyer−Villiger” type concerted oxygen insertion into MTO, forming methoxyrhenium trioxide. The key to the low-energy transition state is the donation of electron density, first, from HOO(−) to the –CH_3 group (making –CH_3 more nucleophilic and HOO− more electrophilic) and, second, from the Re−C bond to both the forming Re−O and breaking O−O bonds, simultaneously (thus forming the Re−O bond as the Re−C bond is broken). In turn, the ability of MTO to undergo these transfers can be traced to the electrophilic nature of the metal center and to the absence of accessible d-orbitals. If accessible d-orbitals are present, they would most likely donate the required electron density instead of the M−CH_3 moiety, and this bond would thus not be broken. It is possible that other metal centers with similar qualities, such as Pt^(IV) or Ir^V, could be competent for the same type of chemistry

Impact of the Implementation of the Construction Guidelines Practiced Among Industries in Cabanatuan City During Pandemic

Most countries have directed a complete lockdown as the World Health Organization (WHO) announced the corona-virus 2019 (COVID-19) outbreak as a pandemic. Covid 19 cases bring out an alarming increase. It can be seen everywhere through limited mobility and the closure of many on-site businesses and some industries. Human resources as one of the utmost in the construction industry's operations are greatly affected by the pandemic that cannot escape, with some complete shutdowns. Most projects have been put on hold until further notice. The condition resulted in addressing prudently the pandemic's impact at the start and end of the crisis making everyone to future readiness and preparations. The study was purposely understanding the extent of the impact of the pandemic on the implementation of the construction guidelines among the selected construction industries in Cabanatuan City. The findings divulged that majority of the participants were in middle management level positions, and 47 percent of the respondents with an average of 9.5 years of construction work experience had 5 years or less experience. Initial measures through the dissemination of information creating awareness were implemented by most establishments including construction firms along with the social distancing, sanitation, and provision of PPE’s as resumption underwent. Respondents experienced the impact of the pandemic on the implementation of the construction guidelines to a moderate extent in terms of materials; manpower; and equipment. The significant relationship between the implementation of the construction guidelines and its impact during the pandemic manifested a positive relationship. Therefore, the researchers concluded that the pandemic impacted the implementation of the construction guidelines among the selected construction industries in Cabanatuan City

Reproductive Biology of Common Small Pelagic Fishes in Manila Bay, Philippines

Reproductive biology of the three dominant species (Sardinella gibbosa, Sardinella fimbriata, and Rastrelliger kanagurta) were studied in Manila Bay from January 2014 to December 2015. The data were collected from landed catch (coming from gillnet, lift net, purse seine, ringnet, and trawl) and during the actual trawl fishing survey. A total of 2,383 Sardinella gibbosa, 2,334 Sardinella fimbriata, and 549 Rastrelliger kanagurta were analyzed by pooling the two years data. The overall female to male ratio conformed to the expected 1:1 sex ratio. These species spawn throughout the year with major peak in March and April and minor peak in October to December for Sardinella gibbosa; with major peak in February to May and minor peak in October to December for Sardinella fimbriata; and for Rastrelliger kanagurta, with major peak in October to December and minor peak in May and June. The GSI values correlate with the maturation of the gonads of these species. The length at maturity (Lm50) was calculated at 12.75 cm in males and 13.25 cm in females for S. gibbosa; 12.25 cm in males and 12.75 cm in females for S. fimbriata; and 25.5 cm in males and 24.5 cm in females for R. kanagurta

Exposure of periodontal ligament progenitor cells to lipopolysaccharide from Escherichia coli changes osteoblast differentiation pattern

Periodontal ligament mesenchymal stem cells (PDLMSCs) are an important alternative source of adult stem cells and may be applied for periodontal tissue regeneration, neuroregenerative medicine, and heart valve tissue engineering. However, little is known about the impact of bacterial toxins on the biological properties of PDLSMSCs, including self-renewal, differentiation, and synthesis of extracellular matrix. Objective : This study investigated whether proliferation, expression of pro-inflammatory cytokines, and osteogenic differentiation of CD105-enriched PDL progenitor cell populations (PDL-CD105+ cells) would be affected by exposure to bacterial lipopolysaccharide from Escherichia coli (EcLPS). Material and Methods : Toll-like receptor 4 (TLR4) expression was assessed in PDL-CD105+ cells by the immunostaining technique and confirmed using Western blotting assay. Afterwards, these cells were exposed to EcLPS, and the following assays were carried out: (i) cell viability using MTS; (ii) expression of the interleukin-1 beta (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF-α) genes; (iii) osteoblast differentiation assessed by mineralization in vitro, and by mRNA levels of run-related transcription factor-2 (RUNX2), alkaline phosphatase (ALP) and osteocalcin (OCN) determined by quantitative PCR. Results : PDL-CD105+ cells were identified as positive for TLR4. EcLPS did not affect cell viability, but induced a significant increase of transcripts for IL-6 and IL-8. Under osteogenic condition, PDL-CD105+ cells exposed to EcLPS presented an increase of mineralized matrix deposition and higher RUNX2 and ALP mRNA levels when compared to the control group. Conclusions : These results provide evidence that CD105-enriched PDL progenitor cells are able to adapt to continuous Escherichia coli endotoxin challenge, leading to an upregulation of osteogenic activities

A Hydrostratigraphic Model of the Pahute Mesa - Oasis Valley Area, Nye County, Nevada

A 3-D hydrostratigraphic framework model has been built for the use of hydrologic modelers who are tasked with developing a model to determine how contaminants are transported by groundwater flow in an area of complex geology. The area of interest includes Pahute Mesa, a former nuclear testing area at the Nevada Test Site (NTS), and Oasis Valley, a groundwater discharge area down-gradient from contaminant source areas on Pahute Mesa. To build the framework model, the NTS hydrogeologic framework was integrated with an extensive collection of drill-hole data (stratigraphic, lithologic, and alteration data); a structural model; and several recent geophysical, geological, and hydrological studies to formulate a hydrostratigraphic system. The authors organized the Tertiary volcanic units in the study area into 40 hydrostratigraphic units that include 16 aquifers, 13 confining units, and 11 composite units. The underlying pre-Tertiary rocks were divided into six hydrostratigraphic units, including two aquifers and four confining units. The model depicts the thickness, extent, and geometric relationships of these hydrostratigraphic units (''layers'' in the model) along with all the major structural features that control them, including calderas and faults. The complexity of the model area and the non-uniqueness of some of the interpretations incorporated into the base model made it necessary to address alternative interpretations for some of the major features in the model. Six of these alternatives were developed so they could be modeled in the same fashion as the base model
