Published: July 2016

AbstractBackgroundThe aim of the study was to assess the performance of the new Continuous Mononuclear Cell Collection (CMNC) protocol on the Spectra Optia Apheresis System for collecting autologous Peripheral Blood Stem Cells (PBSC) in adult patients with respect to collection variables, CD34+ cells harvest prediction and engraftment data. In this retrospective study, 39 CMNC procedures on 23 mobilized patients with multiple myeloma and lymphoma were analyzed. CD34+ cells and blood cells yields, collection efficiencies (CE1 and CE2), cell losses were calculated. Engraftment data of 17 autologous transplantations were collected.ResultsApheresis duration was 239 min for a product volume of 220 mL. Cell product haematocrit, MNC and platelets counts were acceptable (respectively 2.4%, 65%, 834 x 109/L). Median platelet loss was 27.3%. Median CD34+ CE1 and CE2 were 64.6% and 48.5% respectively. We harvested 2.92 × 106CD34+ cells/kg, with a CD34 dose ≥ 2 × 106/kg for 67% of the procedures. Linear correlation between preapheresis CD34 count and the CP CD34 dose/kg allowed a prediction model with a decrease trend for high WBC precount. Procedures were well tolerated. For 17 autologous transplantations, median time to neutrophils and platelets reconstitutions were 12 and 13 days respectively.ConclusionsSpectra Optia CMNC protocol successfully collected CD34+ cells with yields permitting the harvest of sufficient enriched grafts for autologous transplantation. The CD34+ cell yield prediction was excellent. PBSC collection with CMNC protocol had advantages of high processing rate, low product volume, and acceptable contamination by platelets. J. Clin.

AbstractBackgroundAlthough many apheresis centers offer extracorporeal photopheresis (ECP), little is known about current treatment practices.MethodsAn electronic survey was distributed to assess ECP practice internationally.ResultsOf 251 responses, 137 met criteria for analysis. Most respondents were from North America (80%). Nurses perform ECP at most centers (84%) and the majority of centers treat adults only (52%). Most centers treat fewer than 50 patients/year (83%) and perform fewer than 300 procedures/year (70%). Closed system devices (XTS and/or Cellex) are used to perform ECP at most centers (96%). The most common indications for ECP are acute/chronic skin graft versus host disease (89%) and cutaneous T‐cell lymphoma (63%). The typical wait time for ECP treatment is less than 2 weeks (91%). Most centers do not routinely perform quality control assessment of the collected product (66%). There are device‐specific differences in treatment parameters. For example, XTS users more frequently have a minimum weight limit (P = 0.003) and use laboratory parameters to determine eligibility for treatment (P = 0.03). Regardless of device used, the majority of centers assess the clinical status of the patient before each procedure. Greater than 50% of respondents would defer treatment for hemodynamic instability due to active sepsis or heart failure, positive blood culture in the past 24 h or current fever.ConclusionThis survey based study describes current ECP practices. Further research to provide evidence for optimal standardization of patient qualifications, procedure parameters and product quality assessment is recommended.

AbstractImage persistence and flicker are major issues for low‐frequency driving of LCDs. Detailed investigation of the mechanisms that produce these phenomena, using image analysis with a scientific CMOS camera, enabled us to reduce it to acceptable levels. We successfully developed a 7.0‐in. WUXGA (1200 × RGBW × 1920) reflective color LCD driven by low‐temperature polysilicon TFTs at 1 Hz.
Oxidative Cleavage of S–S Bond During the Reduction of Tris(pyridine‐2‐carboxylato)manganese(III) by Dithionite in Sodium Picolinate–Picolinic Acid Buffer Medium

Published: July 2016

ABSTRACTThe reduction of tris(pyridine‐2‐carboxylato)manganese(III) by dithionite has been investigated within the temperature window 288–303 K and at pH range 5.22–6.10 in sodium picolinate–picolinic acid buffer medium. The reaction obeys the following stoichiometry:urn:x-wiley:05388066:media:kin21022:kin21022-math-0001The reaction is described in terms of a mechanism that involves an initial complex formation between S2O42− and [MnIII(C5H4NCO2)3] followed by S–S bond cleavage to give 2HSO3− and [MnII(C5H4NCO2)2(H2O)2] as the products via the formation of SO2●− radical anion. Kinetics and spectrophotometric evidences are cited in favor of the suggested mechanism. Thermodynamic parameters associated with the equilibrium step and the activation parameters with the rate‐determining step have been computed.

SummaryObjectiveMetabolic dysfunction characterized by insulin resistance (IR) is an important risk factor for type‐2 diabetes and coronary artery disease (CAD). The aim of this study was to determine if clinical lifestyle interventions differing in scope and intensity improve IR, defined by the lipoprotein IR (LPIR) score, in individuals differing in the severity of metabolic dysfunction.MethodsSubjects with diagnosed type‐2 diabetes, CAD or significant risk factors participated in one of two clinical lifestyle modification interventions: (i) intensive non‐randomized programme with a strict vegetarian diet (n = 90 participants, 90 matched controls) or (ii) moderate randomized trial following a Mediterranean‐style diet (n = 89 subjects, 58 controls). On‐treatment and intention‐to‐treat analyses assessed changes over 1 year in LPIR, lipoprotein profiles and metabolic risk factors in intervention participants and controls in both programmes.ResultsIn the on‐treatment analysis, both interventions led to weight loss: [−8.9% (95% CI, −10.3 to −7.4), intensive programme; −2.8% (95% CI, −3.8 to −1.9), moderate programme; adjusted P < 0.001] and a decrease in the LPIR score [−13.3% (95% CI, −18.2 to −8.3), intensive; −8.8% (95% CI, −12.9 to −4.7), moderate; adjusted P < 0.01] compared with respective controls. Of the six lipoprotein parameters comprising LPIR, only large very‐low‐density lipoprotein particle concentrations decreased significantly in participants compared with controls in both programmes [−26.3% (95% CI, −43.0 to −9.6), intensive; −14.2% (95% CI, −27.4 to −1.0), moderate; P < 0.05]. Intention‐to‐treat analysis confirmed and strengthened the primary results.ConclusionA stringent lifestyle modification intervention with a vegetarian diet and a moderate lifestyle modification intervention following a Mediterranean diet were both effective for improving IR defined by the LPIR score.
Indolo[3,2‐b]carbazole‐based poly(arylene vinylene)s. The influence of substitution position on spectroscopic and electrochemical properties

Published: July 2016

AbstractThree novel soluble poly(arylene vinylene)s containing indolo[3,2‐b]carbazole moiety inserted in the polymer chain at 2,8‐, 3,9‐ and 6,12‐positions were synthesized and used to study the influence of the linking topology on the optical and electronic properties. The new polymers were obtained through a palladium‐catalysed cross‐coupling Stille reaction between bis‐bromine[3,2‐b]indolocarbazoles and trans‐1,2‐bis(tributylstannyl)ethane in toluene. Polymers were soluble in chlorinated, aromatic and aprotic polar solvents. The structures of polymers were investigated using Fourier transform infrared, 1H NMR and 13C NMR spectroscopies. The number‐average molecular weights determined using gel permeation chromatography are in the range (6.3–9.4) × 103 g mol−1 while thermogravimetric analysis showed the polymers to possess high thermal stability. UV‐visible and emission spectroscopy evidenced a bathochromic shift of λmax for indolocarbazole linking topology in the polymer backbone, in the order: 6,12 < 2,8 < 3,9. Electrochemical properties were investigated by cyclic voltammetry using thin films cast on platinum disc working electrodes and highest occupied and lowest unoccupied molecular orbital energy levels were determined. © 2016 Society of Chemical Industry
XXIX.—On the Application of Graphic Methods to the Determination of the Efficiency of Machinery
Authors: Jenkin Fleeming 
Published: July 2016

§ 31. In a previous paragraph (29) the loaded dynamic frame (fig. 38) for one position of a direct-acting horizontal steam-engine has been described, and the mode of drawing that frame explained, on the assumption that the loads La, Lb, Lc, Ld, are known: it was stated that these loads had been calculated for one particular engine. The present paper gives the varying effort which this engine is capable of exerting at each part of its stroke with given pressures (both constant and varying) in the cylinder, and given constant velocities of the crank-axle. The same calculations show the efficiency of the engine at each part of the stroke, and its total efficiency under the same circumstances. This problem has, it is believed, never hitherto been solved so as to take into account all the circumstances of mass, weight, and friction.§ 32. No pains has been taken in the choice of the particular example. The object of the paper is not so much to draw general conclusions as to all steam-engines—which, indeed, differ too much in arrangement to make this feasible—as to show how, by a method of no great complexity, full information can be obtained as to any particular engine or class of engines.
XXXIII.—Colour, in Practical Astronomy, Spectroscopically Examined
Authors: Smyth Piazzi 
Published: July 2016

Colours and colour sensations are much referred to still by double-star observers, who make use of a most extensive range of names, and differ widely from each other, in describing the many different tints which they claim to recognise by simple eye-observation in those interesting objects.Material coloured shades, generally in glass, are also of daily use in both terrestrial and nautical astronomy, in decreasing or qualifying the intensity of sun's, moon's, and other rays; while special varieties of such media are still being inquired after for acting, if possible, with improvement of, rather than detriment to, the nicest definition of the optical instruments concerned.And again coloured glasses have been latterly demanded, which should allow only the strictest mono-chromatic light to pass through them in one or another particular grade of the spectrum,—so as to allow, as one example only, the solar red-prominences to be plainly and broadly observed, without the usual spectroscopic draw-back of having to look at them through the narrowest of slits.
XII.—On the Solid Fatty Acids of Coco-Nut Oil
Authors: Robinson G. Carr 
Published: July 2016

Most common oils and fats are mixtures of ethereal salts, termed glycerides or glyceric ethers, formed from glycerine and acids of the fatty, the oleic, and other allied series.Of the methods employed for the decomposition of oils and fats, the following are the most usual:—
1.Distillation of the oil or fat; those which yield volatile acids, such as the acetins, butyrins, &c., may be more or less distilled without decomposition; but those which yield fixed acids, e.g., palmitin, olein, &c., are almost wholly decomposed by a heat of 300° C., yielding acrolein, numerous hydrocarbons, &c.2.Distillation with dilute sulphuric acid, by which the volatile acids are separated from the non-volatile.3.Distillation in a current of superheated steam, when the glycerides are decomposed, the fatty acids being liberated.4.Saponification; oils and fats are decomposed by caustic alkalies into glycerine and a soap, the soap, when boiled with dilute sulphuric or hydrochloric acid, being decomposed into a sulphate or chloride of the alkali employed and the fatty acid set free.
XIII.—On the Tabulation of all Fractions having their Values between Two Prescribed Limits
Authors: Sang Edward 
Published: July 2016

The object sought to be gained by this tabulation may be best seen by considering a specific case. When we wish to produce, by help of toothed wheels, a certain ratio between the rotations of two axes, we must have that ratio represented by integer numbers, and these numbers must contain no prime factors exceeding the limit of the number of teeth which can conveniently be cut in any wheel. If, for example, we wish to represent the mean motions of the planets, we have to express the ratios of their periodic times by decomposable numbers; and as this, in general, can only be done approximately, we have to prescribe some limit of error on either side, and have to seek for all fractions between those limits, and then among these to search for those that are suitable.In my treatise on wheel-teeth a solution of this problem is given, complete so far as the discovery of the fractions is concerned, but imperfect in this, that it does not place those fractions in the order of their magnitudes. I propose now to supply this deficiency by explaining an exceedingly simple process, which enables us to make a complete list, arranged in the order of their values, of all irreducible fractions whose denominators shall not exceed some specified number; and also to take up and interpolate any portion of the list. This process is founded on a general theorem flowing directly from the doctrine of continued fractions, but of which the following simple demonstration may be given.
XXVII.—On a New General Method of Preparing the Primary Monamines, &c.
Authors: Morrison R. Milner 
Published: July 2016

Having occasion at one time to require a quantity of methylamine, I tried a number of the best methods given in text-books and books of reference, but the smallness of the yield and the great trouble involved in the processes drew my attention to the fact that there was room for a good method of preparing the primary monamines. Hofman's method, viz., heating the iodides of the alcoholic radicals with ammonia, is of little use, as the trouble of separating the diamines and triamines formed at the same time is so great as to make the process practically useless if the primary monamines alone are required.Keeping this fact before me, I tried for some years, in the intervals of more systematic work, to find the solution of this problem, and I think I have now found a process which, at the same time simple and inexpensive, gives a large yield of the primary monamines. This result has not been arrived at without several failures, and as I think that even negative results are often useful, I shall briefly refer to them. In the first place, together with Professor E. A. Letts, I tried to obtain methylamine from oxamate of methyl. As oxamate of methyl has the following constitutional formula, viz.—

XI—On the Curves produced by Reflection from a Polished Revolving Straight Wire
Authors: Sang Edward 
Published: July 2016

If light, emanating from a fixed source, be reflected to the eye, also fixed, from the surface of a polished cylinder, which cylinder changes its position in some definite manner, the point of reflection moves in some curve or locus whose nature may be made the subject of investigation.In the present paper I propose to examine that case in which an indefinitely thin cylinder is restricted to pass through a fixed point. The locus of the point of reflection is then a curved surface, For the present I shall still farther restrict the polished line to the plane passing through the vertex, the source of light, and the eye ; the locus being then a plane curve.Let then a fine polished straight line, extended indefinitely both ways, turn on the vertex O, while light emanating from the source A is reflected to the eye at B; it is required to investigate the locus of the point C at which the reflection takes place.The reflection is only possible while the polished line passes outside of the angle AOB. When the wire lies along AO, the point of reflection is at A ; when along OB, at B; and when it is equally inclined, outwards, to OA and OB, the reflection occurs at O, wherefore the curve must pass through the three points O, A, and B.
A Renewal of Astronomy Edcuation in Vietnam
Authors: Wentzel Donat G. 
Published: July 2016

AbstractVietnam was scientifically completely isolated for almost 30 years. With French help, several lecture courses have introduced modern astrophysics to Vietnamese physicists, and four students are studying abroad. The IAU program “Teaching for Astronomy Development” (TAD) has concentrated on modernizing the on-going astronomy course for students in the third year of the pedagogical universities. Three one-to-two week “Teachers’ Workshops” have served to introduce selected up-to-date astronomical topics and a few modern teaching methods. The TAD program has also provided appropriate journals, books, a PC and educational software. A new text, Astrophysics, in Vietnamese and English on facing pages and with color pictures – apparently a first for any textbook in Vietnam – will first be used starting in September 2000.Future additional activities: collaboration to plan a new astronomy course in the twelfth grade of the natural science branch of the secondary schools; collaboration so that the 41-cm telescope and astronomers in Hanoi can produce some simple quality science; helping the only planetarium in Vietnam to acquire a wider range of offerings; helping to create a set of B.Sc.-level astrophysics courses for three universities; and supporting the Vietnamese Astronomical Society in effective public outreach.
Using Television for Astronomy Teaching
Authors: Fierro Julieta 
Published: July 2016

AbstractThe full potential of television for education has not been used in developing nations. It is relatively inexpensive to produce astronomy programs that can be broadcast taking advantage of satellite transmissions.We suggest that these programs should have the following elements in order to be efficient:
1Be in the local language.2Be short enough so that the teacher has a chance to comment on them during a one-hour lecture.3Show experiments specially if they are meant for schools that do not have laboratory facilities.4Be produced for several educational levels, including programs aimed for teacher training.Inexpensive books should be edited in the local language in order to serve as an educational complement to the television series.
The Egyptain 1.88-m Telescope
Authors: Osman Anas M. I. 
Published: July 2016

AbstractThe Kottamia 1.88-m reflecting telescope in Egypt is the largest in the Middle East and North Africa. An extensive upgrading programe has been undertaken for this telescope to increase its efficiency. A new Zerodur optical system has been delivered by Carl Zeiss, Germany, and a new CCD system including an acquisition Camera Tek 1024 x 1024 pixels, with pixel size 24 x 24 micron and LN cooling, and an offset guiding camera Kodak 1080 x 1024 pixels with pixel size 16 xl6 micron and thermoelectric cooling. This CCD system has been attached to the Newtonian focus for direct imaging with scale 22.5 arcsec mm-1. The aluminizing plant has also been refurbished by Balzer, the new pumping system can accommodate mirrors up to 2m. The unit is supplied with a microprocessor, which controls and checks all recoating steps, closes all valves and stops the operation in any emergency. A Cassegrain spectrograph (donation from Okayama Astrophysical Observatory, Japan) will be attached to the telescope, after modification, for use with a CCD camera instead of the image-intensifier used before. This spectrograph will be used to obtain medium-dispersion and low dispersion spectra for faint stars and galaxies down to 15th magnitude.

Published: July 2016

AbstractAstronomical researches in Tajikistan are carried out by the Institute of Astrophysics, Tajik Academy of Sciences. The main scientific fields of investigation are physics and dynamics of asteroids, comets and meteors, variable stars and observations of artificial Earth satellites. The Institute has three observational stations: the Gissar observatory (at an altitude 730 m above sea-level) with photographic fireball and meteor patrols, a 70-cm reflector, a 40-cm Zeiss astrograph, a high-precision astronomical telescope (D=1 m, F=0.75 m), etc.; the Sanglokh observatory (at an altitude 2300 m above sea-level) with a Ritchey-Chretien 1-m telescope and 0.6-m reflector by Carl Zeiss; the Pamir observatory (at an altitude 4350 m above sea-level) with a 70-cm reflector. In 1999 the Department of Astronomy was restored in the Tajik State National University and the first students were admitted to this university for the astronomical profession.
Astronomy in the Republic of Macedonia
Authors: Mijatovic Mijat 
Published: July 2016

Astronomy in the territory of today’s Republic of Macedonia has a century-long history. This history is presented in the essay, begining with M. Trpkovic’s suggestions to reform the orthodox calendar in 1900s, through the foundation of the first faculty of Macedonian language in Skopje in 1946, until today’s situation in astronomy.In second half of the twentieth century, the development of astronomy in the Republic of Macedonia is divided in two different periods: before and after the big earthquake in Skopje in 1963. The first period is characterized by hope and enthusiasm, and a little observatory was started to be built, but it was destroyed in the earthquake. The last ten years a new upsurge is seen in Astronomy in the Republic of Macedonia, which is founded on Balkan and international collaboration.

Published: July 2016

AbstractOn today’s Internet, resources for astronomical research abound, and are available from wherever a connection is available. These are mostly in the form of freely accessible databases, ranging from literature services to space-mission archives. They offer instant access to the latest published data and papers, and unique opportunities for archival and innovative research. A sampling of such services will be listed, with notes on accessibility from far-flung points on the planet.
