Abstract:

Using Ayesha Harruna Atta’s <em>The Hundred Wells of Salaga</em> as a stepping-stone, this research paper sets out to delve into the gendered structure of slavery. The article argues that the straightjacket of patriarchal masculinity with its attendant human toll was instrumental in mediating female slavery in pre-colonial Africa. That slavery exacted a heavy toll amongst African women is borne out in the physical and psychological woes of such characters as Aminah, Khadija, and, to a lesser extent, Wurche.

In Ghana, about 13% (~ 4 million) of the population suffers from a mental disorder, ranging from mild and moderate (7%) to severe forms (3%) of mental illness. However, treatment gap for mental disorders, including depression, remains unacceptably high: only about 2% of those diagnosed with a mental disorder receive treatment. This descriptive cross-sectional study investigated the levels of perceived need for mental health care in high school students with depression.

All CDRs used to safely rule out PE have been created and tested within hospital or acute care environments.

It’s a problem as old as the industry itself. The initial oil rush in the late 1800s spread like wildfire through Pennsylvania, and by 1891 the state’s annual crude output had hit 31 million barrels, or 58% of the nation’s total oil production for that year. However, by the turn of the century the bloom was off the rose. Pennsylvania’s once-robust oil allure had been eclipsed by finds in Texas, California, and Oklahoma, each spawning its own regional oil booms. So why the history lesson?

Such wells represent highly conductive pathways leading to non-negligible flow across chemically distinct layers of an aquifer—a phenomenon known as ambient flow.

Using CRMP models allows you to quickly assess the trends in the impact of injection wells on producing wells and build reliable short-term forecasts for fluid production.

Jatibarang structure, situated in Jatibarang low, one of the prolific sub-basin in the northwest Java basin, belongs to PT. Pertamina EP working area. One hundred seventy wells have been drilled, from which there were 56 production wells. Forty production wells were sunk on a volcanic reservoir. Since 1970, volcanic Jatibarang has faced disputed facies concepts, porosities heterogeneity, and permeability system. A fractured reservoir model was proposed. It was due to unique high-performance hydrocarbon in the early years, and then steeply depleted in the early next 3 years, and flat over 20 ye

AbstractThe West Firsby Oilfield exemplifies the classic east Midlands oil play, sourced by early Namurian pro-deltaic shales. Stacked fluvio-deltaic sandstone reservoirs of latest Namurian to early Westphalian 'A' age are structured into a Variscan inversion anticline in the hanging wall of the northeastern boundary fault of the Dinantian-Namurian Gainsborough Trough. The Enterprise West Firsby-1 discovery well, drilled on a 'Top Westphalian 'A'' seismic depth closure, encountered oil-bearing sandstones at three levels. These are thought to represent the earliest Westphalian 'A' Sub-Alton/Cra

Abstract:

The Osprey gas field was discovered in 1975 in the western offshore area of Brunei Darussalam. Two discovery wells penetrate the hanging wall of two separate growth faults and are associated with bright seismic amplitudes. Multiple thin reservoirs are separated by shales of 10 to a few hundred meters in thickness. In addition to seismic tuning of thin layers, there are many shallow gas clouds above these reservoirs, which cause significant and varying amount of push-down in seismic time data. Visualizing as seismic depth data reduces the amount of push-down but doesn’t remove it totally becaus

AbstractRecent research, stimulated by the growing awareness of the sleep apnea syndrome, has shown that nasal breathing plays a major role in the regulation of respiration in sleep. These observations are not new; they confirm century-old clinical findings on the importance of nasal breathing in sleep. The earliest account of the deleterious effects of mouth breathing in sleep was made by Lemnious Levinus towards the end of the sixteenth century. Two hundred years later, Catlin dedicated an entire book to the superiority of nasal breathing over mouth breathing in sleep; and in the late 1800's

X-ray diffraction (XRD) experiments are used to investigate the strain state of both the well and the barriers. The QW transition energy are measured by low temperature photoluminescence (PL). A large quantum confined Stark effect is observed leading to QW luminescence much lower than the emission line of the GaN buffer layer f

In the case of airborne diseases, pathogen copies are transmitted by droplets of respiratory tract fluid that are exhaled by the infectious that stay suspended in the air for some time and, after partial or full drying, inhaled as aerosols by the susceptible. The risk of infection in indoor environments is typically modelled using the Wells-Riley model or a Wells-Riley-like formulation, usually assuming the pathogen dose follows a Poisson distribution (mono-pathogen assumption). Aerosols that hold more than one pathogen copy, i.e. poly-pathogen aerosols, break this assumption even if the aeros

The lithostratigraphy and biostratigraphy of the seven wells show, that the late Quaternary of Læsø can be divided into four units: 1) a lower clay unit, which biostratigraphically is nearly identical with the type-section of the marine late Eemian - early Weichselian Skærumhede Se

For each well, a quantitative relationship between water level and volumetric strain can be inferred from water-level fluctuations due to earth tides and barometric pressure. The observed co-seismic water-level changes, which ranged from −16 to +34 cm, can therefore be compared with volumetric strain recorded by borehole strainmete
