Water Flow Path Characterization in Shallow Vadose Zone Using Tensiometers  [PDF]
Mohammad Hassan Rezaie-Boroon, Omar Acosta, Rodrigo Chipres, Cheryl Cox, Frank Diemel, Norman Ho, Shaonan Li, Ricardo Lopez, Matthew Luque, Mayra Martinez, Dennis Palacios, James Wright
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.99071
Abstract: In this project, we will present the findings of a study using Tensiometer systems designed to investigate the water flow path pattern in shallow vadose zone. The purpose of this paper is to evaluate water flow path in shallow vadose zone and to calculate the infiltration rate and hydraulic conductivity of a soil using Tensiometer. We have measured the subsurface water flow paths in sandy clay loam soil following infiltration experiment using Tensiometers. The matric potential and hydraulic conductivity measurements show that subsequent infiltration and water movement in unsaturated (vadose) zone are vertical, but it can have large lateral component under steady condition. This shows that water moves generally from high water content to lower water content region. Average pressure head for the percolation test conduction locations EB and HB was -30 and -80 cm respectively. Hysteresis produces another interesting situation when the soil is drained. We found that the wetter portion of the soil in vadose zone could be at a lower potential (head) than the dryer portions, resulting in lateral driving force for a preferential flow of water from the dryer to the wet soil. The infiltration rate for the 5 cm ponded water was calculated at 5.45 cm/hr. The infiltration rate curve shows that the rate of infiltration decreases with the time. When infiltration first starts, the wetting front is steep and very close to the surface. Similarly, due to the pressure head gradient, large value for infiltration is recorded. Under these conditions, we believe that the gradient in pressure head is responsible for the rapid movement of water into the dry soil. The effect of gravity is less on water during the initial stages of infiltration; however, it is more effective for preferential flow pattern. In the latter infiltration event, the wetting front has moved deeper into the soil. As a result, the pressure head gradient at the surface is much smaller and consequently has little effect. When the pressure head is equal zero, infiltration rate approaches almost to the lowest level. We also observed that even a minor change in soil-water pressure due to slope could change both direction and magnitude of water flux.

Abstract: Introduction: Humans have gone through physical changes over the last 4 million years. The mouth, however, has not changed teeth quantity or quality. Eight incisors for fruits, vegetables and tubers; four little canines for little animals; eight premolars and twelve flat molars are used for crushing these foods, especially whole grains and legumes. The teeth crushing foods are the first step in the building of faecal matter. Foods are selected mostly according to cultural guidelines than to biological needs. The patterns of consumption are induced by the publicity of industrialized or processed foods. Material and Methods: This study design was observational, analytical, correlational, transversal and prospective. One thousand children (0 - 12 years old) were questioned in order to learn about the relationship between Weekly Eating Frequency (WEF) and Faecal Matter (FM) characteristics. The FM was classified as soft, normal or hard and the outcome was expressed as Dry Faecal Residue (DFR). The WEF and Weekly Bowel Movement Frequency (WBMF) were determined and tabulated according to times per week. Environmental factors, parents’ education level and children’s birth order were examined. Results: There was a strong association between DFR, WBMF and WEF. Environment and education level did not play a key role although birth order did matter. Conclusions: Fibre-free foods (dairies, meats, flours and sweeties or sodas) increased DFR. Foods containing fibre from vegetables decreased DFR, which in turn contributed to the WBMF. Lowest DFR was observed in children under Exclusive Breastfeeding (EB). Distant last-born children had higher DFR. Comments: Daily examples support these results and it is clear that children’s FM is built by their parents. We encourage parents to follow the “mouth nature” rather than the “advertisements nature”.
Inguinal Neuritis in Open Recurrent Hernia Repair  [PDF]
Robert Charles Wright, Robert James Wright
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.513106

PURPOSE: To investigate the pattern of occurrence of inguinal neuritis in recurrent inguinal hernia. We hypothesize that neuritis will occur in more nerves with a wider distribution than in primary repair. METHODS: Retrospective chart review of thirty consecutive recurrent inguinal hernia repairs concentrating on the occurrence of inguinal neuritis. These are not chronic pain patients. Nerves suspected of containing inguinal neuritis were sent for histologic examination. Ilioinguinal nerves were routinely resected. Operative parameters and nerve pathology reports were reviewed. These data were compared with a recent series of one hundred consecutive primary inguinal hernia repairs with a 34% incidence of inguinal neuritis. An independent statistician from Whitman University reviewed the data. RESULTS: Twenty patients were found to have inguinal neuritis among thirty recurrent open inguinal hernia repairs (66%). This compares to 34% among primary repairs, but it is a similar rate (P > 0.42) assuming that the damaged nerve was left intact in 34% of these recurrences during the primary repair. In recurrent inguinal hernia 69% of neuritis occurred in the ilioinguinal nerve compared to 88% of damaged ilioinguinal nerves in the primary hernia. A test for the difference in proportions gives P > 0.10. The most common site of neuritis occurrence in recurrent hernias with nerve damage to the ilioinguinal nerve was at the external oblique neuroperforatum among 70% of patients compared to 83% in primary cases. A test for difference in proportions gives P > 0.36. Two separate nerves were found to exhibit neuritis in six patients (20%) significantly higher than 1% among primary hernias (P < 0.01). CONCLUSION: The overall incidence of inguinal neuritis was 66% in recurrent inguinal hernia repairs. The ilioinguinal nerve was most commonly affected in these recurrent hernias. Inguinal neuritis occurs more commonly in recurrent hernia compared with primary inguinal hernia; however, it has a similar distribution. Neuritis occurs in two nerves with 20% frequency (P < 0.01), so all nerves should be assessed during recurrent herniorrhaphy. The data support the hypothesis.

Socio-Cultural Identities, Perceptions of Sexuality/Sexual Behavior and Cultural Contexts as Determinants of HIV and AIDS Prevalence in Southern Africa  [PDF]
Chijioke Uwah, Susan Wright
World Journal of AIDS (WJA) , 2012, DOI: 10.4236/wja.2012.21003
Abstract: This paper attempts to examine the connection between one’s socio cultural setting and the prevalence of HIV/AIDS. Often, local communities form the contexts within which people negotiate their social and sexual lives and identities. These communities also play a key role in enabling or restraining people from taking control over their health. The paper will try to demonstrate through specific examples that in African societies, sexual behavior is a product of one’s socio-cultural environment and structural contexts and not the cognitive properties of the individual. The article draws from the qualitative study (Focus group sessions, individual interviews) conducted in three high schools in the Boland area of the Western Cape with about 18 learners, 3 Life skills teachers, 3 Performer-Educators on the efficacy of the HIV/AIDS intervention by The Centre for HIV/AIDS Management theatre group based at the University of Stellenbosch. The aim of the study was to ascertain the cultural content of their campaign model as well as their knowledge of the determinants of sex and sexuality of their target areas. Based on the findings of this study, I argue that theatre will achieve greater success in its campaign against HIV/AIDS in South Africa if the designers of the campaign models adopt a more participatory approach, make indigenous culture central to the design of their intervention model and pay closer attention to what Campbell refers to as “community level of analysis” which simply put implies a greater understanding of the target audiences local communities and its determinants of sex and sexuality.
What Is Narcissistic Personality Disorder? Lay Theories of Narcissism  [PDF]
Kirstie Wright, Adrian Furnham
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.59124

There are various studies on mental health literacy which examine lay people’s knowledge and understanding of various mental disorders. Many are interested in beliefs about cause, manifestation and cure as well as the relationship between those beliefs. This study examines lay beliefs regarding the manifestations, aetiology and treatment of Narcissistic Personality Disorder (NPD), and their determinants using a questionnaire divided into three parts. Participants (N = 201) answered 45 attitudinal statements designed for this study regarding NPD. They consisted of 18 manifestation items, 15 aetiology items and 12 treatment items referring to NPD. They also completed the Narcissistic Personality Inventory. Each section of the questionnaire was factor analysed to determine the structure of those beliefs. Factors derived from a principle component analysis of lay beliefs demonstrate poor knowledge of NPD. Factors derived from the manifestations, aetiology and treatment section were modestly and coherently correlated. No demographic factors correlated with all aspects of mental health literacy and lay theories. People are surprisingly misinformed about NPD. They believed that narcissists manifested superficiality and social problems, business abilities and fragility. No distinction was made between biological and psychological causes or genetics and early negative events. Inability to identify NPD may account for many reports of sub-clinical narcissism being associated with leadership derailment.

Associated or Concomitant Diseases Influence Significantly the Health-Sickness Concept in Celiacs  [PDF]

Abstract: It is well-known that feeling to be a healthy or sick person most probably results from the mind than from the body. We all know healthy people who feel sick and vice versa. We were interested in the health and sickness feeling of celiac people, their autorating of these feelings and its conditioning factors as well as their expectations. In this paper we present the results of an inquiry to evaluate these situations. We performed a descriptive, transversal and prospective study for 2 years to groups of celiacs and their families. They received a closed inquiry to be completed before the beginning of the talk. The inquiry included personal data and the co-existence of associated or concomitant (AoC) diseases. Most of the sample’s patients felt to be a healthy person (86.8%). Mothers see their children as healthy and the auto rated criteria is significantly better than the adult celiac person (“t”= -6.024 (p = 0.000)). AoC diseases influenced negatively in the feeling of being healthy and strongly decreased the autorating. Longer time passed on treatment reflects an increase feeling of health and of the autorating. In people with AoC diseases and who feel sick, the increased time of treatment did not show significant differences. People with “gluten sensitivity” felt sicker and auto rated themselves with a lower number than celiacs. Many pediatric gastroenterologists notice that the newly agreed definition of celiac disease, referring it as “autoimmune, chronic, incurable, and multisystemic”, results in a very negative character of the condition which might compromise the future labour of this people as well as their admittance to different health insurance systems.
Fronteras del corazón shamánico: Azares y dilemas Qom
Av?? , 2010,
Abstract: in this paper i analyze certain dilemmas and paradoxes of modernity in the case of the takshek qom or eastern toba (formosa province, argentina). to do so i focus on the experience of the heart or lkillakte, defined as the person's key vital and existential center. within it thoughts and emotions occur, and it also houses different kinds of shamanic power. from a symbolic approach, i explore what happens with the shamanic heart under the influence of catholicism and evangelism, stressing their definitions of the sacred and numinous power, illness and therapy. in this sense, i suggest to regard the heart as a place-process that has widened its boundaries, redefining its anatomy and ontological physiology. thus, as a sensible, metonymic operator, i argue that the contingencias of shamanic hearts condense events, symbols and meaningful metaphors of qom history.
