Increased Risk

Increased exploitation and use of petroleum resources is leading to increased risk of petroleum contamination of soil and groundwater. Although phytoremediation is a widely-used and cost-effective method for rehabilitating soils polluted by petroleum, bacterial community structure and diversity in soils undergoing phytoremediation is poorly understood. We investigate bacterial community response to phytoremediation in two distinct petroleum-contaminated soils (add prepared petroleum-contaminated soils) from northwest China, Weihe Terrace soil and silty loam from loess tableland. High-throughput sequencing technology was used to compare the bacterial communities in 24 different samples, yielding 18,670 operational taxonomic units (OTUs). The dominant bacterial groups, Proteobacteria (31.92%), Actinobacteria (16.67%), Acidobacteria (13.29%) and Bacteroidetes (6.58%), increased with increasing petroleum concentration from 3000 mg/kg–10,000 mg/kg, while Crenarchaeota (13.58%) and Chloroflexi (4.7%) decreased. At the order level, RB41, Actinomycetales, Cytophagales, envOPS12, Rhodospirillales, MND1 and Xanthomonadales, except Nitrososphaerales, were dominant in Weihe Terrace soil. Bacterial community structure and diversity in the two soils were significantly different at similar petroleum concentrations. In addition, the dominant genera were affected by available nitrogen, which is strongly associated with the plants used for remediation. Overall, the bacterial community structure and diversity were markedly different in the two soils, depending on the species of plants used and the petroleum concentration.

Self Administered Questionnaire

Computer-administered self-interviewing (CASI) has been advocated as a way of overcoming underreporting of sensitive sexual behaviors. The present study compared reports of consensual and nonconsensual sexual behaviors (including childhood and adulthood sexual victimization) among women using CASI ( n = 1014) versus a self-administered questionnaire (SAQ; n = 318). Women, ages 18-30 years old, were recruited through random-digit dialing in the community. Response rates were significantly higher for the SAQ, which was sent and returned by mail (87.6% of those eligible), than for the CASI, which involved in-person assessment at a central location (61.4%). There were a few modest differences in reports of consensual or nonconsensual sexual behavior according to mode of administration, suggesting greater willingness to report sexual experiences among the SAQ sample. Mailed SAQ following telephone contact and with financial incentive may be a cost-effective way of obtaining data on sexual behavior from a community sample.

Background and Objective: Congregational Health Empowerment and Social Safety Advocates (CHESSAdvocates) initiative, a project aimed at mitigating maternal and child health (MCH) and gender injustices in religiously pluralistic societies, was implemented in two Northern Nigerian states of Benue and Kaduna between September 2018 and July 2019. The objective of this study was to assess the effectiveness, sustainability and factors of success in the CHESS-Advocates model as a faith community approach to mitigating gender and MCH injustices in Northern Nigeria. Methods: Data were from desk review of monthly project reports which were documented monthly all through the 10-month project life, and qualitative assessment conducted in July 2019 at the end of project. The assessments involved focus group discussions, key informant interviews, and in-depth interviews conducted in four randomly selected communities in each of the project states. The variables of interest were sustainability, effectiveness of initiative, and the factors that contributed to the success of the program. Results: The CHESS-Advocate model was effective in the mobilization of community response that improved uptake and acceptance of antenatal care (ANC), immunization, and uptake of human immunodeficiency virus (HIV) testing services. The model was cost-effective and able to instigate change in harmful practices, particularly in highly religious communities. The model showed promise of sustainability and identified some factors that led to its success in the different communities. Conclusion and Global Health Implications: The CHESS advocates model showed promises of efficacy in engaging faith communities as important actors in promoting MCH practices and mitigating gender injustices particularly in rural and underserved communities. Like other faith based models, the CHESS-Advocates model provided opportunities in faith congregations for building sustainable development in health and social justice. The model helped to improve MCH seeking behavior, influenced change in harmful gender norms and in community response against gender based violence in rural communities.

Gynecologic Neoplasms

The female reproductive tract may be the site of a wide variety of benign and malignant tumors, as well as non-neoplastic tumor-like conditions, most of which can be diagnosed by light microscopic examination including special stains and more recently immunoperoxidase techniques. Nevertheless there are situations where ultrastructural examination can contribute substantially to an accurate and specific diagnosis. It is my opinion that electron microscopy can be of greatest benefit and is most cost effective when applied in conjunction with other methodologies. Thus, I have developed an approach which has proved useful for me and may have benefit for others. In cases where it is deemed of potential value, glutaraldehyde-fixed material is obtained at the time of frozen section or otherwise at operation. Coordination with the gynecologic oncologist is required in the latter situation. This material is processed and blocked and is available if a future need arises.

Ibm Pc

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

Abstract Using the iPad tablet for Augmentative and Alternative Communication (AAC) purposes can facilitate many communicative needs, is cost-effective, and is socially acceptable. Many individuals with communication difficulties can use iPad applications (apps) to augment communication, provide an alternative form of communication, or target receptive and expressive language goals. In this paper, we will review a collection of iPad apps that can be used to address a variety of receptive and expressive communication needs. Based on recommendations from Gosnell, Costello, and Shane (2011), we describe the features of 21 apps that can serve as a reference guide for speech-language pathologists. We systematically identified 21 apps that use symbols only, symbols and text-to-speech, and text-to-speech only. We provide descriptions of the purpose of each app, along with the following feature descriptions: speech settings, representation, display, feedback features, rate enhancement, access, motor competencies, and cost. In this review, we describe these apps and how individuals with complex communication needs can use them for a variety of communication purposes and to target a variety of treatment goals. We present information in a user-friendly table format that clinicians can use as a reference guide.

There are a multitude of reasons that a teletinnitus program can be beneficial, not only to the patients, but also within the hospital and audiology department. The ability to use technology for the purpose of tinnitus management allows for improved appointment access for all patients, especially those who live at a distance, has been shown to be more cost effective when the patients travel is otherwise monetarily compensated, and allows for multiple patient's to be seen in the same time slots, allowing for greater access to the clinic for the patients wishing to be seen in-house. There is also the patient's excitement in being part of a new technology-based program. The Gulf Coast Veterans Health Care System (GCVHCS) saw the potential benefits of incorporating a teletinnitus program and began implementation in 2013. There were a few hurdles to work through during the beginning organizational process and the initial execution of the program. Since the establishment of the Teletinnitus program, the GCVHCS has seen an enhancement in patient care, reduction in travel compensation, improvement in clinic utilization, clinic availability, the genuine excitement of the use of a new healthcare media amongst staff and patients, and overall patient satisfaction.
