Carnets de Géologie , 2006,
Abstract: A stratonomic and micropaleontological analysis of the Aptian marls cropping out in the La Tuilière area near Saint-Saturnin-lès-Apt (Vaucluse, SE France), enabled us to reconstitute a continuous succession almost 120 m thick, that includes the upper terms of the Lower Aptian (Bedoulian) and the lower part of the Middle Aptian (Gargasian). These levels had never before been observed with such continuity in the Gargas region, the Aptian historical stratotype.
Le Gargasien (Aptien moyen) de La Tuilière - St-Saturnin-lès-Apt (région du stratotype historique de l'Aptien, Vaucluse, SE France) : localisation géographique et corrélations des affleurements
Moullade Michel,Tronchetti Guy,Balme Christine,Kouyoumontzakis Georges
Carnets de Géologie , 2006,
Abstract: L'analyse stratonomique et micropaléontologique des affleurements de marnes aptiennes du secteur du hameau de La Tuilière, près de Saint-Saturnin-lès-Apt (Vaucluse, SE France), nous a permis de reconstituer une série continue, épaisse de près de 120 m, comprenant les termes supérieurs de l'Aptien inférieur (Bédoulien) et la partie inférieure de l'Aptien moyen (Gargasien). Ces niveaux n'avaient jamais pu être observés avec une telle continuité dans la région de Gargas, stratotype historique de l'Aptien

Applicability of Age-Based Hunting Regulations for African Leopards
Guy Andrew Balme, Luke Hunter, Alex Richard Braczkowski
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0035209
Abstract: In species in which juvenile survival depends strongly on male tenure, excessive trophy hunting can artificially elevate male turnover and increase infanticide, potentially to unsustainable levels. Simulation models show that the likelihood of safe harvests can be improved by restricting offtakes to males old enough to have reared their first cohort of offspring to independence; in the case of African leopards, males were ≥7 years old. Here, we explore the applicability of an age-based approach for regulating trophy hunting of leopards. We conducted a structured survey comprising photographs of known-age leopards to assess the ability of wildlife practitioners to sex and age leopards. We also evaluated the utility of four phenotypic traits for use by trophy hunters to age male leopards in the field. Our logistic regression models showed that male leopard age affected the likelihood of survey respondents identifying the correct sex; notably, males <2 years were typically misidentified as females, while mature males (≥4 years) were sexed correctly. Mature male leopards were also more likely to be aged correctly, as were portrait photographs. Aging proficiency was also influenced by the profession of respondents, with hunters recording the lowest scores. A discriminant model including dewlap size, the condition of the ears, and the extent of facial scarring accurately discriminated among male leopard age classes. Model classification rates were considerably higher than the respective scores attained by survey respondents, implying that the aging ability of hunters could theoretically improve with appropriate training. Dewlap size was a particularly reliable indicator of males ≥7 years and a review of online trophy galleries suggested its wider utility as an aging criterion. Our study demonstrated that an age-based hunting approach is practically applicable for leopards. However, implementation would require major reform within the regulatory framework and the hunting industry.

South African Medical Journal , 2012,
Abstract: Context. Information on childhood poisoning in the developing world, including South Africa, is scarce, despite its contribution to morbidity and mortality. Objective. We describe the profile of children with exposures and poisonings presenting to Red Cross War Memorial Children’s Hospital (RCWMCH) in Cape Town, South Africa, from 2003 to 2008 and compare the trends of causative agents over the past two decades. Methods. Cases were identified by review of the RCWMCH case records. Results. Of the total incidents (N=2 872), paraffin (kerosene) was the commonest agent (n=692, 24%) with 124 poisonings including two deaths. Drugs were the most common toxin group (n=988, 34%), including 139 single-drug poisonings with 5 deaths; 4 associated with traditional medicine use. Household cleaning product incidents (n=302, 10%) resulted in 29 singleproduct poisonings with no deaths. Pesticide incidents (n=311, 10%) included 6 deaths; 203 (65%) incidents were due to organophosphates or carbamates. The suburban distribution of the main toxin groups varied. Comparing 1987 and 2008, the number of incidents decreased from 1 116 to 447; drug and paraffin incidents decreased respectively (from 673 to 150 and from 332 to 87), household cleaning products and cosmetics increased (21 to 69) and pesticide incidents increased (7 to 69). Conclusion. Despite a decrease in the overall number of incidents over two decades at RCWMCH, paraffin and drugs remain the principal agents responsible for paediatric exposures and poisonings, with increasing incidents due to household cleaning products and pesticides. Identification of these toxin groups coming from specific suburbs allows for targeted prevention initiatives.
Reducing Land Degradation on the Highlands of Kilimanjaro Region: A Biogeographical Perspective  [PDF]
Christine Noe
Open Journal of Soil Science (OJSS) , 2014, DOI: 10.4236/ojss.2014.413043
Abstract:

In 2012, governments across the world adopted “The Future We Want” outcome document in Rio De Janeiro as a commitment to achieve a land-degradation-neutral world. This document reasserts the importance of sustainable land management in the top of the debates on sustainable development. This paper provides an overview of Tanzania’s preparedness towards achieving these global objectives. The paper is based on a keynote address which was presented in the conference on reducing land degradation on the highlands of Kilimanjaro Region in Tanzania. Using a biogeographical perspective, the paper assesses challenges of adopting programmatic approach to sustainable land management in Tanzania. It also presents some opportunities that exist through Global Mechanism of the United Nations Convention to Combat Desertification, which promote actions leading to coordination, mobilization and channeling of financial resources to assist member countries to coordinate and sustain sustainable land management projects.

Compressors for Hyper-Sonic Engines —A Theoretical Study of Future Compressors for Hyper Sonic Engines  [PDF]
Christine Cherian
Advances in Aerospace Science and Technology (AAST) , 2018, DOI: 10.4236/aast.2018.34007
Abstract:
This paper is an eye opening to the new horizon of the design of operational Compressors in our jet engines. That are compressors usually perform an operation called isentropic process and which levitate the pressure and temperature to the optimum level which require for effective ignition. Basically, our compressors have several sets of blades to perform this function, more precisely saying Rotor and stator blades. Where rotor blade provides air molecule to push at very high velocity to the Stationary blade and when the air Enders to the Stator, the stator races its pressure to move on to the next stage. And we call this set of Stator and rotor as a stage ref [1]. However, in this work, I consider the geometry of the incoming air molecule and how it transforms its physical quantities such as Pressure and temperature ref [2]. For that I tie the concept of Thermodynamic and mechanics on the platform of Tensor analysis ref [3]. That is, I consider the quantities like Pressure, Temperature and rate of flow are their corresponding vector spaces and energy related quintets like heat, work as the scaling elements on the above vector space. And quantities such as entropy enthalpy and specific heat capacity are corresponding physics of it. Considering the advantages, one of the important advantages of this approach is the applicability of results of this work to the formulation of blade less compression Example: Ram and Scram jet engine. Again, the relevant upgrading which is essential for future hypersonic air crafts can achieve from this study and this will be a mile stone for bright air and space travel. To conclude, this approach will be a great transformation on the conventional idea for realization of compression for operational Scram and Ram jet engines ref [4] [5].
The Significance of African Lions for the Financial Viability of Trophy Hunting and the Maintenance of Wild Land

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0029332
Abstract: Recent studies indicate that trophy hunting is impacting negatively on some lion populations, notably in Tanzania. In 2004 there was a proposal to list lions on CITES Appendix I and in 2011 animal-welfare groups petitioned the United States government to list lions as endangered under their Endangered Species Act. Such listings would likely curtail the trophy hunting of lions by limiting the import of lion trophies. Concurrent efforts are underway to encourage the European Union to ban lion trophy imports. We assessed the significance of lions to the financial viability of trophy hunting across five countries to help determine the financial impact and advisability of the proposed trade restrictions. Lion hunts attract the highest mean prices (US$24,000–US$71,000) of all trophy species. Lions generate 5–17% of gross trophy hunting income on national levels, the proportional significance highest in Mozambique, Tanzania, and Zambia. If lion hunting was effectively precluded, trophy hunting could potentially become financially unviable across at least 59,538 km2 that could result in a concomitant loss of habitat. However, the loss of lion hunting could have other potentially broader negative impacts including reduction of competitiveness of wildlife-based land uses relative to ecologically unfavourable alternatives. Restrictions on lion hunting may also reduce tolerance for the species among communities where local people benefit from trophy hunting, and may reduce funds available for anti-poaching. If lion off-takes were reduced to recommended maximums (0.5/1000 km2), the loss of viability and reduction in profitability would be much lower than if lion hunting was stopped altogether (7,005 km2). We recommend that interventions focus on reducing off-takes to sustainable levels, implementing age-based regulations and improving governance of trophy hunting. Such measures could ensure sustainability, while retaining incentives for the conservation of lions and their habitat from hunting.

Caroline Mills, Christine Chapparo
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.77102
Abstract: Many students with autism and intellectual disability demonstrate atypical sensory behaviours which impact on their schooling. Few studies provide empirical support for teachers using planned sensory activities in special education classrooms. Aim: To determine whether a classroom based Sensory Activity Schedule (SAS) improves behavioural outcomes for one student with ASD who demonstrated atypical sensory processing and associated challenging behaviour. Methods: Critical case study methods were used to describe changes in the frequency of challenging behaviour “incidents” recorded for one eight year old student with autism over one school term during implementation of a Sensory Activity Schedule. Results: There was a reduction in the reported frequency of challenging behaviour incidents which were associated with sensory triggers over one school term. Conclusion: When applied with caution, in context, and with appropriate training, a Sensory Activity Schedule was associated with a reduction in challenging behaviour incidents for one student with autism during classroom activities.
Online or Face-to-Face Microbiology Laboratory Sessions? First Year Higher Education Student Perspectives and Preferences  [PDF]
Susan Salter, Christine Gardner
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.714189
Abstract: Reducing the number of face-to-face laboratory sessions and supplementing with virtual/online alternatives are critical to managing the combined pressures of increasing first-year student numbers and decreasing university budgets. Most of the research studies about online practicals are hypothesis generating rather than hypothesis testing thus only providing initial support and direction for the generation of pedagogically sound online laboratory teaching. This pilot study investigated the effectiveness of using a combination of online and face-to-face practical sessions to enable students in a Microbiology unit, offered to students completing several health science courses, to connect discipline-specific theory and practical application. Quantitative and qualitative data were gathered using a paper-based questionnaire from 72 first-year students. Results showed that 65 percent of students preferred a combination of face-to-face and online sessions. Furthermore, determinants for engagement with online sessions varied with student gender.
