The redundancy of student comments and numerical ratings in evaluations of teaching.

Journal of allied health

Leonard DL, Marion R, Niebuhr BR.
PMID: 3980285
J Allied Health. 1985 Feb;14(1):141-7.

Student evaluation of teaching effectiveness is widely used in undergraduate institutions as one element of determining overall faculty effectiveness. The evaluation format typically consists of (1) a number of questions the student answers by indicating a numerical rating and...

Thioamination of Alkenes with Hypervalent Iodine Reagents.

Chemistry (Weinheim an der Bergstrasse, Germany)

Mizar P, Niebuhr R, Hutchings M, Farooq U, Wirth T.
PMID: 26660291
Chemistry. 2016 Jan 26;22(5):1614-7. doi: 10.1002/chem.201504636. Epub 2016 Jan 07.

An efficient thioamination of alkenes mediated by iodine(III) reagents is described. The use of different sulfur nucleophiles allows the flexible synthesis of 1,2-aminothiols from alkenes. By employing chiral iodine(III) reagents, a stereoselective version of the thioamination protocol has also...

Mode stabilization of a laterally structured broad area diode laser using an external volume Bragg grating.

Optics express

Niebuhr M, Zink C, Jechow A, Heuer A, Glebov LB, Menzel R.
PMID: 25969324
Opt Express. 2015 May 04;23(9):12394-400. doi: 10.1364/OE.23.012394.

An external volume Bragg grating (VBG) is used for transverse and longitudinal mode stabilization of a broad area diode laser (BAL) with an on-chip transverse Bragg resonance (TBR) grating. The internal TBR grating defines a transverse low-loss mode at...

Roles of deltoid and rotator cuff muscles in shoulder elevation.

Clinical biomechanics (Bristol, Avon)

Liu J, Hughes RE, Smutz WP, Niebur G, Nan-An K.
PMID: 11415669
Clin Biomech (Bristol, Avon). 1997 Jan;12(1):32-38. doi: 10.1016/s0268-0033(96)00047-2.

OBJECTIVE: The objective of this study was to measure abduction moment arms of the supraspinatus, subscapularis, infraspinatus, and deltoid (anterior, middle, and posterior portions) muscles during humeral elevation in the scapular plane (abduction). DESIGN: Moment arms were measured by...

Research, robots, and reality: A statement on current trends in biorobotics.

The Behavioral and brain sciences

Niebur E, Elhilali M, Obeid I, Werfel J, Blanchard M, Frasca M, Ghose K, Hofstoetter C, Indiveri G, Tilden MW.
PMID: 18241384
Behav Brain Sci. 2001 Dec;24(6):1072-1073. doi: 10.1017/S0140525X01450126.

While robotics has benefited from inspiration gained from biology, the opposite is not the case: there are few if any cases in which robotic models have lead to genuine insight into biology. We analyze the reasons why biorobotics has...

Correlation of pain scores, analgesic use, and beck anxiety inventory scores during hospitalization in lower extremity amputees.

The open orthopaedics journal

Trame CD, Greene E, Moddeman G, Booth BA, Konstantakos EK, Parada S, Siebuhr K, Laughlin RT.
PMID: 19478937
Open Orthop J. 2008 Oct 24;2:145-50. doi: 10.2174/1874325000802010145.

Post amputation pain can be debilitating for patients and families. Chronic pain is a common phenomenon after lower extremity amputation, occurring in up to 80% of this population. The purpose of this pilot study was to correlate post amputation...

Storage and packaging effects on sensory and color characteristics of ground beef.

Meat science

Montgomery JL, Parrish FC, Olson DG, Dickson JS, Niebuhr S.
PMID: 22063115
Meat Sci. 2003 Aug;64(4):357-63. doi: 10.1016/S0309-1740(02)00171-7.

Effects of irradiation (2 kGy) of ground beef patties from trimmings stored aerobically for 0 or 6 days on lean color, odor, and sensory attributes were investigated. Beef trimings were coarse ground and split into 2 groups. Group one...

Self-organized criticality occurs in non-conservative neuronal networks during Up states.

Nature physics

Millman D, Mihalas S, Kirkwood A, Niebur E.
PMID: 21804861
Nat Phys. 2010 Oct;6(10):801-805. doi: 10.1038/nphys1757.

During sleep, under anesthesia and in vitro, cortical neurons in sensory, motor, association and executive areas fluctuate between Up and Down states (UDS) characterized by distinct membrane potentials and spike rates [1, 2, 3, 4, 5]. Another phenomenon observed...

Complications in laparoscopic surgery.

Surgical technology international

Niebuhr H, Nahrstedt U, Hollmann S, Rückert K.
PMID: 21400429
Surg Technol Int. 1995;173-7.

Over the last few years, laparoscopic surgery has gained widespread acceptance in surgical practice. The indications range has expanded extraordinarily in that time. Some of the practiced procedures are already considered the gold standard, while others are still on...
