Kilowatt-peak-power, single-frequency, pulsed fiber laser near 2 μm.

Optics letters

Geng J, Wang Q, Jiang Z, Luo T, Jiang S, Czarnecki G.
PMID: 21685997
Opt Lett. 2011 Jun 15;36(12):2293-5. doi: 10.1364/OL.36.002293.

We generated single-frequency pulses at kilowatt peak power from an all-fiber Tm-doped master oscillator power amplifier system, which is the first report of this kind (to the best of our knowledge) of a laser in the 2 μm region....

Ortop Traumatol Rehabil. 2006 Jun 30;8(3):288-90.

The Internet is one of the fastest developing information source, especialy in the medical-knowledge aspect. The article presents the possible choice of WWW pages concerning the pathology of the wrist.

A microfluidic electrochemical detection technique for assessing stability of thin films and emulsions.

Journal of colloid and interface science

Mostowfi F, Czarnecki J, Masliyah J, Bhattacharjee S.
PMID: 17964591
J Colloid Interface Sci. 2008 Jan 15;317(2):593-603. doi: 10.1016/j.jcis.2007.09.068. Epub 2007 Sep 29.

An experimental technique is developed for assessing stability of thin liquid films by application of electric potential to compress the liquid film and to simultaneously measure the electrical properties of the system. The concept involves creating a thin film...

Discovery of an intermediate phase in bis-thiourea pyridinium chloride inclusion compound.

The Journal of chemical physics

Pajzderska A, Wasicki J, Czarnecki P, Toupet L, Collet E.
PMID: 19191394
J Chem Phys. 2009 Jan 28;130(4):044503. doi: 10.1063/1.3065983.

This paper reports the occurrence of a new phase for bis-thiourea pyridinium chloride inclusion compound, which is intermediate to the high- and low-temperature ones already reported. The structure of the intermediate phase was determined by the x-ray diffraction and...

Extraction and Purification of Pasteuria spp. Endospores.

Journal of nematology

Chen SY, Charnecki J, Preston JF, Dickson DW.
PMID: 19270952
J Nematol. 2000 Mar;32(1):78-84.

Pasteuria penetrans is an endospore-forming bacterial parasite of root-knot nematodes that has potential as a biological control agent. Biochemical investigations of P. penetrans are limited because of difficulty in obtaining large quantities of endospores free of plant debris and...

Calculation of the one- and two-loop lamb shift for arbitrary excited hydrogenic states.

Physical review letters

Czarnecki A, Jentschura UD, Pachucki K.
PMID: 16383880
Phys Rev Lett. 2005 Oct 28;95(18):180404. doi: 10.1103/PhysRevLett.95.180404. Epub 2005 Oct 27.

General expressions for quantum electrodynamic corrections to the one-loop self-energy [of order alpha(Zalpha)6] and for the two-loop Lamb shift [of order alpha2(Zalpha)6] are derived. The latter includes all diagrams with closed fermion loops. The general results are valid for...

Evidence for a Contribution of ALA Synthesis to Plastid-To-Nucleus Signaling.

Frontiers in plant science

Czarnecki O, Gläßer C, Chen JG, Mayer KF, Grimm B.
PMID: 23112801
Front Plant Sci. 2012 Oct 29;3:236. doi: 10.3389/fpls.2012.00236. eCollection 2012.

The formation of 5-aminolevulinic acid (ALA) in tetrapyrrole biosynthesis is widely controlled by environmental and metabolic feedback cues that determine the influx into the entire metabolic path. Because of its central role as the rate-limiting step, we hypothesized a...

Children with pain and HIV / AIDS.

Role of asphaltenes in stabilizing thin liquid emulsion films.

Langmuir : the ACS journal of surfaces and colloids

Tchoukov P, Yang F, Xu Z, Dabros T, Czarnecki J, Sjöblom J.
PMID: 24564447
Langmuir. 2014 Mar 25;30(11):3024-33. doi: 10.1021/la404825g. Epub 2014 Mar 11.

Drainage kinetics, thickness, and stability of water-in-oil thin liquid emulsion films obtained from asphaltenes, heavy oil (bitumen), and deasphalted heavy oil (maltenes) diluted in toluene are studied. The results show that asphaltenes stabilize thin organic liquid films at much...

The influence of the thymic preparation thymex-L on deficient antitumor-activity of monocytes from melanoma patients in-vitro.

Oncology reports

Garbin F, Eckert K, Buttner P, Garbe C, Czarnecki J, Maurer H.
PMID: 21597761
Oncol Rep. 1995 May;2(3):469-72. doi: 10.3892/or.2.3.469.

Recently we demonstrated that, in vitro, prothymosin alpha 1 (ProT alpha), a polypeptide from calf thymus, was able to enhance the deranged tumoristatic activity of peripheral blood monocytes from melanoma patients. Now we report, that the thymic preparation Thymex-L...

Structures and phase transitions in a new ferroelectric -- pyridinium chlorochromate -- studied by X-ray diffraction, DSC and dielectric methods.

Pyridinium chlorochromate, [C(5)H(5)NH](+)[ClCrO(3)](-) (hereafter referred to as PyClCrO(3)), was studied by X-ray diffraction, differential scanning calorimetry (DSC) and dielectric methods. Studies reveal three reversible phase transitions at 346, 316 and 170 K with the following phase sequence: R ̅3m...

Kinetics of Particle Transport to a Solid Surface from an Impinging Jet under Surface and External Force Fields.
