In vitro Seed Germination, Protocorm Formation and Plantlet Regeneration in Aerides ringens Fisher
Authors: Pyati Ashok N 
Published: July 2019

An attempt was made to in vitro seed germination and plantlet regeneration in Aerides ringens, a threatened, endemic and epiphytic orchid. Five basal media Knudson C (KC), Vacin and Went (VW), Burgeff’s (N3f), half strength MS, MS were examined for their effectiveness. Germination occurred in all the media. However, KC medium proved to be the best for seed germination (70.8%) and half strength MS was superior for the differentiation of protocorm like bodies (PLBs) into seedlings. The seeds were also cultured on various plant growth regulators (PGRs) to evaluate their effectiveness on seed germination and further differentiation. Among the PGRs tested, 0.57 μM IAA (IAA 89.3%), 4.64 μM Kn (88.6%) and 2.21 μM BAP (90.7%) and 0.57 μM IAA + 0.55 μM BAP (96.5%) were stimulated the germination and further differentiation of PLBs into seedlings. The concentrations of 2.21 μM BAP and combination of 0.57 μM IAA + 0.55 μM BAP stimulated the formation of MPLBs, which later differentiated into shoots and roots. Four potting substrates were evaluated for Ex vitro seedling survivability of which brick: charcoal: decaying litter: coconut husk (1 : 1 : 1 : 1) gave maximum survival rate (89.0%).

Authors: Das Subroto K , Shethi Kishwar Jahan , Hoque MI , Sarker RH 
Published: July 2019

To investigate the integration of chitinase gene in lentil (Lens culinaris Medik.) namely, BARI masur-4 (BM-4), BARI masur-5 (BM-5) and BARI masur-6 (BM-6) through Agrobacterium-mediated genetic transformation was performed using Agrobacterium strain EHA 105 harboring bar (resistant to phosphinotrycin) and chitinase (gene of interest) gene. Selection of transformed shoots was carried out by gradually increasing the concentration of phosphinotrycin (PPT) up to 2.0 mg/l. Transgenic lentil shoots were produced with an overall frequency of 0.36 in case of BM-4 and BM-6 and 0.34 in case of BM-5, respectively. Most of the selected shoots developed in vitro flowers and pods following their sub-culture on half strength of MS supplemented with 20 mg/l IBA, 0.5 mg/l NAA with 50 mg/l ticarcillin. Seedlings germinated from the seeds were successfully transferred to soil for the development of further progeny. Stable integration of target gene was confirmed through PCR analysis.

Lean Management: organizational innovations in hematological Day-Hospitals
Authors: Bianciardi Caterina , Guercini Jacopo 
Published: July 2019

Background. Lean Thinking is a management method which, despite its industrial origins, has spread in health-care environment too.
Objective. To describe the path followed and the results reached implementing Lean Thinking in four case studies.
Methods. Such case studies were conducted in as many hematological Day-Hospitals (DHs), located in Central-Italy. At the beginning of each study, the DH internal processes, activity volumes and patient flows were analyzed and satisfaction questionnaires were administered to both operators and patients. Based on the returned questionnaires, deficiencies were focused on; for each deficiency data was collected and objectives defined. Following such definitions, analysis of inefficiency causes was performed and countermeasures were identified. In the final meeting the results were assessed and monitoring/maintenance methods were defined. All these steps were supported by Lean Thinking instruments for analysis and solution.
Results. Activity organization and patient satisfaction improved everywhere. Time losses and workloads imbalances were minimized in two DHs, particularly through higher standardization in the management of clinical-administrative documents. In another DH, the output capacity of the hospital pharmacy and the workflows in DH were aligned with respect to the course of the day, so reducing delays in the delivery of therapies. Appointment planning was improved in the fourth DH, standardizing time slots (15-minutes) necessary for each therapy, so optimizing the number of beds and chairs used.
Conclusions. Poor management of health care facilities can affect efficiency, security and quality of services provided. Lean Thinking is a valid method to address such problems.

Authors: Bon E. I. , Maksimovich N. Ye. 
Published: July 2019

Investigation of the brain pathology in experimental ischemia requires adequate methods for assessing the neurological deficit that occurs in laboratory animals, including sensory-based and behavioural disorders. In this research, we aimed to compare motor and behavioural disorders in rats with partial and subtotal experimental cerebral ischemia. The rats modelled with cerebral ischemia are found to exhibit a decrease in muscle strength, resistance to hypoxia, motor and emotional activity. The animals with incomplete cerebral ischemia demonstrated more pronounced sensory-based motor and behavioural disorders compared both with those modelled with partial cerebral ischemia and, in particular, with the control group.

Published: July 2019

In this paper, we reported green-emission carbon dots (CDs) using a single step hydrothermal carbonization. The CDs were prepared by m-phenylenediamine, tris, phosphoric acid, and pure water by heating for 8 h at 180 ℃. The CDs exhibited green-emission fluorescence, were sensitive to pH, and was successfully used analysed the pH of real water samples. Besides, the CDs could detect of food additive lemon yellow, with the limit of detection as low as 0.13 μM. More importantly, the CDs could be used as an antioxidant to remove superoxide anions (O2-) and hydroxyl radicals (–OH). The linear range of CDs concentrations for superoxide anion and hydroxyl radicals were 0 - 300 mg/mL and 0 - 14 mg/mL, respectively. In addition, the CDs could be a fluorescnet reagent in bioimaging of beer yeast, mould and onion skins. The favorable pH, optical properties, antioxidant ability, and bioimaging ability ensure the CDs can be exploited in food analysis and other fields.

Abstract
We present an analysis of instrument performance using new observations taken with the Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) instrument and the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system. In a correlation analysis of our data sets (which use the broadband mode covering the J band through the K band in a single spectrum), we find that chromaticity in the SCExAO/CHARIS system is generally worse than temporal stability. We also develop a point-spread function (PSF) subtraction pipeline optimized for the CHARIS broadband mode, including a forward modeling-based exoplanet algorithmic throughput correction scheme. We then present contrast curves using this newly developed pipeline. An analogous subtraction of the same data sets using only the H-band slices yields the same final contrasts as the full JHK sequences; this result is consistent with our chromaticity analysis, illustrating that PSF subtraction using spectral differential imaging (SDI) in this broadband mode is generally not more effective than SDI in the individual J, H, or K bands. In the future, the data processing framework and analysis developed in this paper will be important to consider for additional SCExAO/CHARIS broadband observations and other ExAO instruments which plan to implement a similar integral field spectrograph broadband mode.
AXS: A Framework for Fast Astronomical Data Processing Based on Apache Spark
Authors: Zečević Petar , Slater Colin T. , Jurić Mario , Connolly Andrew J. , Lončarić Sven , Bellm Eric C. , Golkhou V. Zach , Suberlak Krzysztof 
Published: July 2019

Abstract
We introduce AXS (Astronomy eXtensions for Spark), a scalable open-source astronomical data analysis framework built on Apache Spark, a widely used industry-standard engine for big-data processing. Building on capabilities present in Spark, AXS aims to enable querying and analyzing almost arbitrarily large astronomical catalogs using familiar Python/AstroPy concepts, DataFrame APIs, and SQL statements. We achieve this by (i) adding support to Spark for efficient on-line positional cross-matching and (ii) supplying a Python library supporting commonly used operations for astronomical data analysis. To support scalable cross-matching, we develop a variant of the ZONES algorithm capable of operating in distributed, shared-nothing architecture. We couple this to a data partitioning scheme that enables fast catalog cross-matching and handles the data skew often present in deep all-sky data sets. The cross-match and other often-used functionalities are exposed to the end users through an easy-to-use Python API. We demonstrate AXS’s technical and scientific performance on Sloan Digital Sky Survey, Zwicky Transient Facility, Gaia DR2, and AllWise catalogs. Using AXS we were able to perform on-the-fly cross-match of Gaia DR2 (1.8 billion rows) and AllWise (900 million rows) data sets in ∼30 s. We discuss how cloud-ready distributed systems like AXS provide a natural way to enable comprehensive end-user analyses of large data sets such as the Large Synoptic Survey Telescope.

Published: July 2019

Abstract
We present the discoveries of a brown dwarf (BD) and a low-mass star from the Kepler and K2 missions. The newly discovered BD is EPIC 212036875b and the low-mass star is KOI-607b. EPIC 212036875b has a mass of M

⋆ = 0.915 ± 0.031 R

eff = 5418 ± 87 K. We also revisit a BD, CWW 89Ab, that was previously published by Nowak et al. (under the designation EPIC 219388192b). CWW 89Ab is one of two known transiting BDs associated with a star cluster, which illustrates the need for more BDs with accurate masses, radii, and reliable age determinations to test theoretical models. We find that the newly discovered BD, EPIC 212036875b, falls in the middle of the so-called BD desert, indicating that EPIC 212036875b is either a particularly rare object, or the BD desert may not be so dry after all.
