This manuscript introduces BITTSy, the Behavioral Infant & Toddler Testing System. This software system is capable of running the headturn preference procedure, preferential looking, conditioned headturn, and visual fixation/habituation procedures. It uses only commercial-off-theshelf (COTS) hardware to implement the procedures in an affordable and space-efficient setup. The software package, example protocols and data sets, and manual are freely available and downloadable from go.umd.edu/BITTSy, making this entire set of procedures available to resource-limited labs. Researchers can easily use BITTSy at multiple sites in a uniform manner, resulting in a standardized, powerful research tool that can enhance cross-site research collaborations.

Non-specific low back pain is a frequent complaint in primary care, but the differential diagnosis for low back pain can be complex. Despite advances in diagnostic imaging, a specific pathoanatomical source of low back pain can remain elusive in up to 85% of individuals. Best practice guidelines recommend that clinicians conduct a focused physical examination to help to identify patients with non-specific low back pain and an evidence-based course of clinical management. The use of sensitive and specific clinical methods to assess the lumbar spine, sacroiliac and hip joints is critical for effective physical examination. Psychosocial factors also play an important role in the evaluation of individuals with low back pain, but are not included in this narrative review of physical examination methods. Physical examination of the lumbar spine, sacroiliac and hip joints is presented, organized around patient position for efficient and effective clinical assessment.

An exploratory study was undertaken to demonstrate the potential for using a fluidized bed riser system for the dry separation of fine particles. The experimental system consisted of a constant-diameter riser, two different operational heights, optional internal rings and one specific test mixture. Good separation efficiencies were obtained with a modest mass flux through the system. Further research is required to optimize the separation process and bring the concept to commercial viability.

An experimental system was constructed and used to obtain data necessary for the evaluation and improvement of a mathematical model for a crossflow coal gasification system. These experimental data were consistent with those of similar gasification processes. The evaluation of the mathematical model indicated the proper trends in the crossflow gasification process; however, the predictions from the model and the data were not at the desired level of agreement. Employing a sensitivity analysis, appropriate correction factors to the heat transfer and chemical kinetics correlations were determined. The addition of these correction factors was necessary to account for the variation in the reactivity of the feedstock. These correction factors were found to produce heat transfer and chemical kinetics expressions which are within the scatter of currently accepted experimental data for these quantities. It was concluded that for the model presented, these experimental correction factors must he evaluated...

A 56 year old, right handed African-American man with past history of left knee osteoarthritis, remote intravenous drug use, remote alcoholism, and seropositivity for hepatitis C was admitted to a local hospital for fatigue, chest pain, 13.6 kg weight loss, night sweats, and vision loss. On examination, a loud systolic murmur was present. An electrocardiogram (ECG) displayed T wave alternans and a transoesophageal echocardiogram revealed severe mitral regurgitation with mitral valve vegetations, ruptured chordae tendineae, and left ventricular ejection fraction of 75%. He was diagnosed as having endocarditis and cytomegalovirus endophthalmitis, and was treated with ceftriaxone, vancomycin, ganciclovir, foscarnet, aspirin, metoprolol, lisinopril, nifedipine, and intravenous esmolol. He developed fever (39.3°C) and his mental status declined. A head computed tomography (CT) scan showed left occipital haemorrhage. His left leg became cold and pale with an ankle:brachial index of 0.4. Blood cultures grew yeast. Amphotericin B was started and he was transferred to our hospital for further care. Upon arrival his temperature was 36.4°C, pulse was 80 beats per minute and regular, respiratory rate was 25 per minute, and blood pressure was 106/76 mm Hg on the right and 160/83 mm Hg on the left. On auscultation a II/VI holosystolic murmur over the apex and bibasilar rales were heard. His left leg was cold with pulses detectable only by Doppler. He was alert and oriented to person and place only, and …

The performance of high-temperature slagging coal-utilization systems depend on the collection of coal ash on the reactor surfaces and the flow of the slag out of the reactor through a slag-tap hole. In order to develop an analytical model for flow of the slag on a reactor wall, existing data for slag viscosity were reviewed in light of new emerging-process conditions. A Bingham model was selected for viscosity and the flow characteristics along a reactor wall are developed.

1.1. The literature on primary carcinoma of the fallopian tube has been reviewed. 2.2. A case of primary carcinoma of the fallopian tube has been reported. 3.3. The desirability of wider general knowledge concerning this disease has been pointed out. 4.4. The variability in the sealing of the fimbriated end of the fallopian tube has been re-emphasized. 5.5. The variability of and the etiology of the vaginal discharge in cases of carcinoma of the fallopian tube has been discussed. 6.6. The inherent danger in diagnostic or surgical handling of a carcinoma of the fallopian tube has been discussed.

PARAESOPHAGEAL hiatus hernia is a congenital defect that is usually found only in adults. Its incidence in general is fairly low, while in infants or the newborn it is extremely low. The paradox of finding an adult type of diaphragmatic hernia in a newborn infant is unique. We are reporting such a case. REPORT OF A CASE I. S., a full-term white girl, was born on Dec. 8, 1951. She appeared normal at birth, but later, when feedings were begun, regurgitation with slight cyanosis was noticed at every attempt to swallow. Physical examination revealed good ventilation of both lungs. The heart tones were clear, and the abdomen was soft. A catheter passed into the esophagus would encounter an obstruction in the distal portion. Chest x-rays showed a gas-filled viscus in the mediastinum to the right and dorsally from the heart. The diagnosis of diaphragmatic hernia was confirmed by an iodized
