Petrochemical and petrophysical characterization of the lower crust and the Moho beneath the West African Craton, based on Xenoliths from Kimberlites

Additional evidence to the composition of the lower crust and uppermost mantle was presented in the form of xenolith data. Xenoliths from the 2.7-Ga West African Craton indicate that the Moho beneath this shield is a chemically and physically gradational boundary, with intercalations of garnet granulite and garnet eclogite. Inclusions in diamonds indicate a depleted upper mantle source, and zenolith barometry and thermometry data suggest a high mantle geotherm with a kink near the Moho. Metallic iron in the xenoliths indicates that the uppermost mantle has a significant magnetization, and that the depth to the Curie isotherm, which is usually considered to be at or above the Moho, may be deeper than the Moho

Recurrence Spectroscopy in Time-Dependent Fields

Closed-orbit theory is a semiclassical technique for explaining the spectra of Rydberg atoms in external fields. We derive an alternative version of closed-orbit theory that applies when the external fields are time dependent. We compare the results of this theory with experiments on lithium atoms in a weak oscillating electric field

Major Thrombotic Event Despite Anticoagulation in a Patient With COVID-19.

The outbreak of coronavirus disease 2019 (known as COVID-19), which started in Wuhan, China in December 2019, is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has been associated with both venous and arterial thromboembolism likely secondary to significant cytokine activation and inflammation. Reports on the incidence of thrombotic complications, however, are not well documented. Our case will examine a young man diagnosed with COVID-19 who developed an acute, severe bilateral saddle pulmonary embolism while on prophylactic dose anticoagulation after being admitted to the hospital and treated for two weeks with significant improvement

Extracting Classical Trajectories from Atomic Spectra

We describe how to reconstruct individual classical trajectories from spectroscopic data. The ac dipole moment of a trajectory can be found from the effect of an oscillating field on the spectrum. The inverse Fourier transform of such data yields the component of the electron trajectory along the direction of the oscillating field. We demonstrate the method by experimentally extracting z(t) for two electron trajectories that influence the Stark spectrum of Rydberg lithium. Within the experimental resolution, the reconstructed orbits agree well with classical predictions

A Rare but Reversible Cause of Lithium-Induced Bradycardia.

Lithium is a well-known medication that has been used for many years to treat mood disorders. One of its side effects is cardiotoxicity, which usually occurs at serum lithium levels \u3e 1.5 mEq/L but rarely occurs when therapeutic levels of lithium are used. Other causes of bradycardia should be eliminated by performing a detailed workup that includes calcium level, thyroid function, and cardiac workup, with consideration of any medication interactions. Lithium-induced bradycardia is reversible upon discontinuation of lithium, but irreversible sinus node can occur and may warrant permanent insertion of a pacemaker to maintain sinus rhythm when long-term lithium therapy is required. Herein, we describe the case of a 42-year-old woman who presented with symptomatic bradycardia. Bipolar disorder was described in her past medical history, and she was receiving lithium therapy. A detailed workup indicated bradycardia secondary to lithium use. Her condition improved after discontinuation of the lithium, and normal sinus rhythm was restored over the next three days

Mycoplasma Genitalium Among Women With Nongonococcal, Nonchlamydial Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is a frequent condition of young women, often resulting in reproductive morbidity. Although Neisseria gonorrhoeae and/or Chlamydia trachomatis are/is recovered from approximately a third to a half of women with PID, the etiologic agent is often unidentified. We need PCR to test for M genitalium among a pilot sample of 50 women with nongonococcal, nonchlamydial endometritis enrolled in the PID evaluation and clinical health (PEACH) study. All participants had pelvic pain, pelvic organ tenderness, and leukorrhea, mucopurulent cervicitis, or untreated cervicitis. Endometritis was defined as ≥5 surface epithelium neutrophils per ×400 field absent of menstrual endometrium and/or ≥2 stromal plasma cells per ×120 field. We detected M genitalium in 7 (14%) of the women tested: 6 (12%) in cervical specimens and 4 (8%) in endometrial specimens. We conclude that M genitalium is prevalent in the endometrium of women with nongonococcal, nonchlamydial PID

Heavy Crane Foundations on Soft Clay

A very large mobile crane was used to lift a 3,150 kN steam generator through the roof of the containment building of a nuclear power plant. The maximum load on the crane was 19.8 MN, giving a track pressure of almost 600 kPa. Soil conditions were stiff clay underlain by softer clay. This paper describes the bearing capacity and settlement analysis performed to establish a suitable shallow foundation for the crane. The foundation load test confirmed that soil conditions had been adequately defined and that the foundation design was satisfactory

Teaching Parenting Skills in a Methadone Treatment Setting

Family factors significantly affect children’s risk of substance abuse, delinquency, and other problem behaviors (Arthur, Hawkins, Pollard, Catalano, & Baglioni, 2002). Children of substance abusers represent a particularly high-risk population. Prenatal exposure to addictive substances and the medical complications that may arise are important factors that, from conception, place this population at high risk of drug abuse and other problem behaviors (Griffith, Azuma, & Chasnoff, 1994). As children of substance abusers mature, their lives are characterized by exposure to continued drug and alcohol abuse by family members, recurrent or chronic illnesses, frequent moves, financial troubles, legal conflicts, family disorganization, and family conflict (Keller, Catalano, Haggerty, & Fleming, 2002; Kolar, Brown, Haertzen, & Michaelson, 1994). Furthermore, substance-abusing parents tend to have poorer family management practices than nonabusers (Kolar et al.). Substance-abusing parents in treatment are dealing not only with their addiction, the possibility of relapse, and struggles with employment and living arrangements, but also with their role as parents and the influence of their addiction on their children (Greif, 2005)
