Published: December 2019

In the competitive, rapidly developing e-commerce market, most of the costs of organizations are associated with logistics and sales promotion. Implementation of fulfillment, i.e. the full range of services provided to e-commerce companies by a universal logistics operator, reduces the costs of goods delivery while ensuring the safety of goods and high quality of service.Aim. The presented study aims to examine and develop methods for improving the logistics processes of companies operating in the e-commerce market.Tasks. The authors examine the specific features and trends on the Russian e-commerce market, analyze the existing methods of delivering goods from online stores to the end consumer, and substantiate the need to apply modern methods of goods delivery.Methods. This study uses general scientific methods of cognition to examine the logistics processes of e-commerce and formulate basic approaches to improving the logistics of online stores.Results. The statistics of the Russian e-commerce market is analyzed. The specific features of logistics in e-commerce and methods of goods delivery are determined. Different types of logistics operators acting in the e-commerce market are examined. The benefits and drawbacks of fulfillment – the full range of services provided to e-commerce companies by a universal logistics operator from the moment a customer places an order to the moment they receive the goods – are identified. It is established that fulfillment for an online store includes the acceptance nad storage of goods, correspondence, and other types of cargo at a specially equipped warehouse, proper packaging of goods that are to be shipped to the consumer, and selection of an optimal delivery scheme depending on urgency and other factors. The necessity of implementing this delivery technology in the operation of an online store is substantiated.Conclusions. Improvement of the methods of goods delivery to the consumers of online stores can reduce logistics costs while providing quality service.

Background and aim: Oral care contributes significantly to the patients’ health outcome in a critical care unit. Nurses play a vital role in maintaining good oral health. However, there remains a dearth of literature regarding oral care practices among nurses workingin an Indian critical care unit. In this descriptive cross sectional study, we assessed the level of awareness and the existing practices of patients’ oral care among our critical care unit (CCU) nurses. Methodology: After obtaining approval from the institutional ethics committee, 64 CCU nurses, having work experience of atleast 6 months in the CCU, were enrolled in this descriptive cross sectional study. A self-structured questionnaire was used to assess the awareness and practice of the nurses. The data collected was analyzed using descriptive statistics and results were expressed as percentages.Result: Of the 64 nurses enrolled in the study, there were no dropouts. It was found that 62 (96.87%) nurses provided oral care to all the CCU patients. 60 (93.7%) nurses claimed that a standard oral care protocol has been provided to them. Documentation of the oral care was carried out by 54 (84.37%) nurses. Although 50% of the nurses had been trained to provide oral care, 54 (84.37%) nurses felt the need of fresh training. 60 (93.7%) nurses preferred using toothbrush in conscious patients. Chlorhexidine was the most commonly used solution. Bleeding, extubation and biting were among the few complications that they faced during routine oral care.Conclusion: Despite working in a rural set up with limited resources available, oral care was provided by most of the nurses. Following a standard protocol and documentation of the same, has helped maintain consistency in oral care of all critical care patients.Citation: Bhavika S, Shetti AN, Mustilwar R, Anshul S.

Abstract
Breast cancer is a burning female health related issue and constantly increasing the threat for women around the globe. This study intends to analyze the power of an educational intervention in form of educational message on television to educate Pakistani women in order to improve their attitudes in adoption of precautionary behavior. The effects of these educational communication strategies are recorded by using the quantitative survey technique and a close ended questionnaire was distributed among the female respondents. A total of 300 women of Lahore Pakistan aged 20-40 were selected. Breast cancer awareness advertising educational message have been disseminated on television by Shaukat Khannum Cancer Hospital have been watched by respondents every year on television are intended to make women aware about the early diagnosis and the results reveal that these educational campaigns are not significantly educating women to develop a precautionary behavior in order to self-examine or tend them toward precautionary measures. Women are aware of breast cancer issues but still not clear about self-examination and consequences of delay in diagnosis of this fatal disease.

Abstract
Amid increasingly regional economic competition, accelerating productivity adhere special importance, whereas boosting the quality over quantity of human-capital comprises an important component of productivity and growth. This research tries to identify the two sister universities: Bacha Khan University at Charsadda (BKUC) and Abdul Wali Khan University at Mardan (AWKUM), students’ perception regarding educational environment. Structured questionnaire method being followed to quantify both universities’ students perception regarding educational, administrative and their response towards job searching. Responses of the students at BKUC were more varied than students at AWKUM. But at structural level, due to the lack of space availability, lack of proper training, number of permanent faculty members, and curriculum design and delivery, students at BKUC are more interested to have libraries, sufficient number of classrooms, permanent faculty members to ease supervisor availability for the purpose to conduct smoothly their academic activities. Whereas, after graduation most of the students hunt for government jobs as compared to other selected areas of work. But due to the development differences of Mardan and Charsadda regions, students at AWKUM prefers to establish their own businesses as compared to BKUC.

Abstract
The study of the extragalactic background light (EBL) in the optical and near-infrared has received a lot of attention in the last decade, especially near the wavelength λ ≈ 3.4 μm, with remaining tension among different techniques for estimating the background. In this paper we present a measurement of the contribution of galaxies to the EBL at 3.4 μm that is based on the measurement of the luminosity function (LF) in Lake et al. and the mean spectral energy distribution of galaxies in Lake & Wright. The mean and standard deviation of our most reliable Bayesian posterior chain gives a 3.4 μm background of I

This result is higher than most previous efforts to measure the contribution of galaxies to the 3.4 μm EBL, but is consistent with the upper limits placed by blazars and the most recent direct measurements of the total 3.4 μm EBL.

Abstract
We report the results of an extensive radio-continuum observing campaign of host galaxies of short gamma-ray bursts (GRBs). The goal of this survey was to search for optically obscured star formation, possibly indicative of a population of young short-GRB progenitors. Our sample comprises the hosts and host-galaxy candidates of 16 short-GRBs from 2005 to 2015, corresponding to roughly one-third of the presently known ensemble of well-localized short bursts. Eight GRB fields were observed with ATCA (at 5.5 and 9.0 GHz), and eight fields with the VLA (mostly at 5.5 GHz). The observations typically achieved a 1σ
rms of 5–8 μJy. In most cases, they were performed years after the corresponding burst. No new short-GRB host with optically obscured star formation was found. Only one host galaxy was detected: that of GRB 100206A at z = 0.407. However, its starburst nature was already known from optical/IR data. Its measured radio flux can be interpreted as being due to a star formation rate of about 60 M
⊙ yr−1. This is in good agreement with earlier expectations based on the observed broad-band spectral energy distribution of this galaxy. The 15 nondetections constrain the SFRs of the suspected host galaxies and provide upper limits on late-time luminosities of the associated radio afterglows and predicted kilonova radio flares. The nondetection of radio emission from GRB explosion sites confirms the intrinsically low luminosity of short-GRB afterglows and places significant constraints on the parameter space of magnetar-powered radio flares. Luminous radio flares from fiducial massive magnetars have not been found.

Abstract
The discovery of quasars a few hundred megayears after the Big Bang represents a major challenge to our understanding of black holes as well as galaxy formation and evolution. Quasars' luminosity is produced by extreme gas accretion onto black holes, which have already reached masses of M

⊙ by z ∼ 6. Simultaneously, their host galaxies form hundreds of stars per year, using up gas in the process. To understand which environments are able to sustain the rapid formation of these extreme sources, we started a Very Large Telescope/Multi-Unit Spectroscopic Explorer (MUSE) effort aimed at characterizing the surroundings of a sample of 5.7 < z < 6.6 quasars, which we have dubbed the Reionization Epoch QUasar InvEstigation with MUSE (REQUIEM) survey. We here present results of our searches for extended Lyα halos around the first 31 targets observed as part of this program. Reaching 5σ surface brightness limits of 0.1–1.1 × 10−17 erg s−1 cm−2 arcsec−2 over a 1 arcsec2 aperture, we were able to unveil the presence of 12 Lyα nebulae, eight of which are newly discovered. The detected nebulae show a variety of emission properties and morphologies with luminosities ranging from 8 × 1042 to 2 × 1044 erg s−1, FWHMs between 300 and 1700 km s−1, sizes <30 pkpc, and redshifts consistent with those of the quasar host galaxies. As the first statistical and homogeneous investigation of the circumgalactic medium of massive galaxies at the end of the reionization epoch, the REQUIEM survey enables the study of the evolution of the cool gas surrounding quasars in the first 3 Gyr of the universe. A comparison with the extended Lyα emission observed around bright (

We use orbit-based, axisymmetric Schwarzschild models to analyze the stellar kinematics of Holm 15A from new high-resolution, wide-field spectral observations obtained with the Multi-Unit Spectroscopic Explorer at the Very Large Telescope. We find a supermassive black hole with a mass of

at the center of Holm 15A. This is the most massive black hole with a direct dynamical detection in the local universe. We find that the distribution of stellar orbits is increasingly biased toward tangential motions inside the core. However, the tangential bias is less than that in other cored elliptical galaxies. We compare Holm 15A with N-body simulations of mergers between galaxies with black holes and find that the observed amount of tangential anisotropy and the shape of the light profile are consistent with a formation scenario where Holm 15A is the remnant of a merger between two ETGs with pre-existing depleted cores. We find that black hole masses in cored galaxies, including Holm 15A, scale inversely with the central stellar surface brightness and mass density. These correlations are independent of a specific parameterization of the light profile.
Kinetic Helicity and Lifetime of Activity Complexes During Solar Cycle 24
Authors: Komm R. , Gosain S. 
Published: December 2019

Abstract
We study magnetic features on the solar surface that exist for several rotations during solar cycle 24. To identify them, we average synoptic maps over a range in latitude and stack the resulting longitudinal strips in time. We use synoptic maps of magnetograms obtained with the NSO/Synoptic Optical Long-term Investigations of the Sun instrument and create synoptic maps of the kinetic helicity of subsurface flows integrated over 2.0–7.1 Mm based on Solar Dynamics Observatory/Helioseismic and Magnetic Imager Dopplergrams. To distinguish between active and quiet regions, we sort the grid points of the synoptic maps by their activity level and divide the data into four subsets with 25% of activity each and into two subsets with the highest or lowest 12.5% of activity values. The kinetic helicity of these six subsets follows the hemispheric helicity rule with, on average, positive values in the southern and negative values in the northern hemisphere. However, the helicity of the subset with the highest activity is about four times higher than that of the other subsets, and the mid-quartile subsets show the weakest hemispheric helicity rule. We define the lifetime of complexes in each subset and find that for the high-activity subset, the amplitude of magnetic activity and kinetic helicity increases almost linearly with the lifetime of complexes. The distribution of flares closely resembles that of the high-activity subset. The flare-productive locations in long-lived complexes produce, on average, the same number of flares as those of short-lived complexes. However, long-lived complexes have a higher fractional number of these locations than the short-lived complexes and thus produce more flares not just because they live longer.

Published: December 2019

ABSTRACT
PURPOSE: To analyze the efficacy, predictability, stability, and safety of laser in situ keratomileusis (LASIK) to correct myopia and myopic astigmatism using the Nidek EC-5000 CX II laser and the Customized Aspheric Transition Zone (CATz) profile.
METHODS: We conducted a retrospective analysis of 100 eyes (50 patients) with myopic astigmatism. A CATz profile was used in all eyes (profile 4) with an ablation zone of 5 mm and a transition zone of 9 mm, using Nidek FinalFit software.
RESULTS: Average patient age was 39 years (range 21 to 69 yr). Preoperative mean spherical equivalent refraction was -4.70 ± 2.53 D (range -11.88 to -0.50 D), mean preoperative sphere was -4.31 ± 2.53 D (range -11.25 to -0.25 D), and mean preoperative cylinder was -0.78 ± 0.69 D (range -3.25 to 0). Postoperative mean spherical equivalent refraction at 6 months was 0.12 ± 0.53 D (range -1.63 to +0.88 D), mean postoperative sphere was 0.02 ± 0.56 D (range -1.50 to +2.00 D), and mean postoperative cylinder was -0.29 ± 0.50 D (range 0 to -1.75 D). Uncorrected visual acuity was 6/6 or better in 58% (58 eyes) and better than 6/12 in 93% (93 eyes).
CONCLUSION: LASIK with the Nidek EC-5000 CX II laser and the CATz profile was effective, reasonably predictable, stable, and safe for correction of myopic astigmatism with a spherical component between -0.25 and -11.25 D, and a cylindrical component up to 3.25 D, using the techniques in this study. Astigmatism was undercorrected with the current algorithm. [J Refract Surg 2004;20 (suppl): S666-S668]

ABSTRACT
PURPOSE: To evaluate the efficacy and predictability of laser in situ keratomileusis (LASIK) using the Nidek NAVEX system with a small ablation (optical, OZ) zone and a large aspheric transition zone (OATz).
METHODS: We report a prospective nonrandomized study of LASIK for high myopia using a small ablation in 23 eyes of 18 patients. The optical zone was between 3 and 3.8 mm and transition zone (TZ) was between 7 and 7.8 mm. Preoperative examination included best-spectacle corrected visual acuity (BSCVA), refraction, and corneal topography. All eyes were measured by the Nidek OPD-Scan and data were imported to FinalFit software. Aspheric profile (OATz) numbers 5 to 7 were used. BSCVA, uncorrected spectacle visual acuity (UCVA), refraction, and subjective evaluation of glare and night vision by questionnaire were recorded after surgery.
RESULTS: At baseline, mean spherical equivalent refraction was -7.03 ± 2.39 D (range -5.50 to -15.50 D). Postoperative UCVA was better than 20/25 in 95.65% of eyes 3 months after LASIK. Post-operative refraction was within ± 0.50 D of emmetropia in 91.3% of eyes and within ± 1.00 D in all eyes. No eye lost lines of BSCVA; 52.17% of eyes gained 1 line and 13.04% of eyes gained 2 lines. No patient reported significant glare or night vision problems on subjective questionnaire.
CONCLUSION: LASIK with a small ablation (optical) zone and high aspheric transition zone using the Nidek NAVEX system was effective, predictable, and relatively safe for correction of high myopia. [J Refract Surg 2004;20(suppl):S669-S673]
