Cloud computing is an internet-based service of delivering technology to users and an important technological facility where mutual resources are delivered on demand. Usage of cloud computing in educational Institutions provides students as well as administrative staff an opportunity to access various applications and knowledge swiftly. Its simplicity, upfront-cost, reduced downtime and less management effort make this service acceptable for all fragments of society particularly students and teachers. Despite the fact that the cloud computing technology is very useful, such as ease of access, cost effective. It has various issues like security violations, data confidentiality, data integrity, regional and geographical restrictions over the data. Safe cloud services are required to protect its users from different external threats such as disclosure or loss of data and compromising of users’ accounts. Users’ understanding about the cloud computing’s advantages, disadvantages and security issues can protect them from potential threats while ensuring its optimal usage in education. In this paper, a survey has been conducted to identify students understanding about the advantages, disadvantages and security issues regarding cloud computing in the educational sector. A sample of 212 respondents from graduate and undergraduate programs was taken to obtain required information. The findings reveal a lack of awareness about the use of cloud computing, its benefits, and security concerns and the implications of this deficiency are critical as multiple issues like outflow of personal data and its loss is faced by its users which may have adverse social, emotional and professional effects on student’s life. Considering the usefulness as well as the sensitivity of cloud computing in educational institutions, Authors propose maximum utilization of cloud computing in educational sector while ensuring the security of its users.

In present day situation, the analysis of drive circuits for DC motors are advancing and recent innovative technologies make the system more cheaper and market friendly. The adjustable speed drive system is utilized for speed control purpose of DC motor. In this paper, open loop analysis and output response is studied for a Single phase full bridge rectifier connected to a DC motor feeding from a DC/DC Buck converter. The voltage regulator between two networks make the load voltage adjustable. The Matlab simulation software is used to analyze the system performance and its characteristics under various factors. The performance parameters such as ripple factor, motor and rectifier efficiency, voltage and current THD, and form factors of the system for various firing angles are compared and analyzed. Moreover it is observed that the system output voltage remains constant eventhough there is load and field disturbance in motor. Besides, if the firing angle increases form factor, ripple factor increases whereas the motor efficiency and rectifier efficiency decreases. The main aim of the paper is to prove that the developed model must transmit power with high efficiency and low ripple compared to existing models. The results presented in this paper match with the experimental results.

Since the number of mobile users has been increased, there comes a number of new mobile operators. This accounts for the increased installation of towers. A critical mobile network consume 40-50MW (approx.) and a diesel generator consume 1MG (approx.) of diesel per day. Also a base station requires greater amount of power employed for its working in which some of its internal applications like light, coolant systems say air conditioning, fans etc., uses the major part of the power utilized. This intensifies the burning of coal which emits carbon dioxide into the atmosphere. At times the number of users for a base station may be very less especially during night time, consuming the power unnecessarily. Our approach is to reduce the intake of power by the base stations during unwanted time. This can be done by establishing communication between the adjacent towers to intimate the unused tower to remain idle or active based on the requirement. Also this approach conveys the measures taken to reduce the power consumed by the internal applications of the base station. The entire setup is under the surveillance of personal computer thereby creating an energy efficient mobile infrastructure with power saving, reduction of CO2 emission which in turn reduces global warming and successful operation of large scale mobile communication services.

In the agriculture sector Continuous water extraction from the earth decreases water level owing to the slow arrival of a lot of soil in the areas of irrigated land. This is also owing to the unexpected use of water, which leads to a substantial quantity of waste. This automatic irrigation system is used for this purpose. Power comes from photovoltaic cells using solar energy. Therefore it is not necessary to rely on erratic business energy. The circuit consists of sensor components constructed with op-amp IC. Op-amps are set up as a comparator here. In the soil are placed two steep copper cables to see if the soil is moist or dry. The entire system is controlled by a microcontroller. IC which contacts are used to turn the engine ON, the engine is switched OFF when the ground is moist. The above task is carried out by the microcontroller, which receives the signal from the sensors and which functions under software control that can be stored on the microcontroller's Rom. The pump situation is shown on a 16X2 LCD interfacing to the microcontroller. The ON / OFF pump situation is shown. The project can also be strengthened through its interfaces with a GSM modem, which allows control of the engine switching.

ABSTRAK

The imposition of capital punishment on narcotics and psychotropic criminals in Indonesia in the perspective of human rights based on the 1945 Constitution needs to be reviewed to understand whether capital punishment is a way of law enforcement that is contrary to human rights. The main problem being the object of research, is the imposition of capital punishment against narcotics and psychotropic criminals violating human rights based on the 1945 Constitution. This research is a normative legal research through a legislative approach, conceptual, case. The data used is secondary data with qualitative data analysis. The results of the study show that the imposition of capital punishment on narcotics and psychotropic criminals does not violate human rights because it does not conflict with the provisions of Article 28A, Article 28I paragraph (1) and Article 28J paragraph (2) of the 1945 Constitution and does not violate Indonesia's international legal obligations that were born from international agreements on the eradication of illicit trafficking in narcotics and psychotropic substances. As a suggestion, law enforcement needs to be improved, because crime / narcotics and psychotropic crimes are transnational types of crime by using high modus operandi.

Arhivski stručnjaci u svojem radu definiraju i koriste se mnoštvom relacija na različite načine. U konkretnim situacijama različito ih razumiju i različito primjenjuju. Od usvajanja prvoga međunarodnog arhivskog standarda ISAD(G), pojam relacije sustavno je ugrađen u opis arhivskih entiteta i zato ga svi koji se bave opisom moraju razumjeti u skladu sa svrhom standarda. U prilogu su predstavljeni teorijski okviri uporabe relacija u različitim kontekstima, koji se temelje na arhivskim standardima. Relacije su kvantitativno definirane, prije svega među krovnim arhivskim entitetima. Sve veća složenost upravljanja krovnim arhivskim entitetima zahtijeva razmjerno veći intelektualni napor arhivskih stručnjaka u odnosu na nestandardizirana rješenja u opisu arhivskih entiteta. U tom će kontekstu biti potrebno razmišljati o rješenjima koje poznajemo pod nazivom umjetna inteligencija.

Kreutzer i drug u Zagrebu. Pretvorbu zavoda u dioničko društvo naziva Banka I. Kreutzer d.d. u Zagrebu godine 1920., ponovnu promjenu naziva tvrtke u Trgovačka banka d.d. godine 1938., pa sve do godine 1948., kada je završena njezina likvidacija. U vrijeme velike svjetske ekonomske krize glavni cilj i poslovno načelo rukovodstva banke bila je puna likvidnost zavoda, tako da je banka poslovala s financijskim dobitkom. U svibnju i lipnju 1941. zaplijenila je i oduzela Državna riznica Nezavisne Države Hrvatske (NDH) sve dionice Trgovačke banke koje su bile registrirane na Židove. Na taj način NDH je došla do većinskoga paketa dionica banke, pa je u zavodu postavila svojega nadzornog povjerenika. Nakon što je u studenom 1941. Tomo Kostopeč, poslovni prijatelj pravih dioničara banke židovske vjeroispovijesti za njihov račun otkupio od NDH dionice zavoda, razriješen je dužnosti postavljeni povjerenik pa je Trgovačka banka mogla nastaviti s radom. Nakon što je u ratu banka izgubila cijeli predratni dobitak, banka je 1946. ušla u postupak likvidacije, koji je završen 1948. godine.

Mutation detection and molecular targeted tumor therapies
Authors: Wang Yamin , Chen Zhong
Published: January 2020

Rapid advancement in genomic technologies has greatly enhanced the potential of clinical recognition and application of molecular targets. Specifically, gene mutation detection technologies are of great significance in the early diagnosis, customized drug delivery guidance, treatment progression, and monitoring of tumor’s drug resistance. Gene mutation detection or genetic typing of patients is a prerequisite for molecular targeted therapies. Most kinds of targeted therapies treat cancers by interfering with specific proteins that are involved in tumorigenesis. Compared with traditional chemotherapies, molecular targeted therapies have many advantages, despite that they still have risks of resistance, side effects and leak of genetic information.
Spinal cord neural stem cells heterogeneity in postnatal development
Authors: Ban Jelena , Mladinic Miranda
Published: January 2020

Neural stem cells are capable of generating new neurons during development as well as in the adulthood and represent one of the most promising tools to replace lost or damaged neurons after injury or neurodegenerative disease. Unlike the brain, neurogenesis in the adult spinal cord is poorly explored and the comprehensive characterization of the cells that constitute stem cell neurogenic niche is still missing. Moreover, the terminology used to specify developmental and/or anatomical CNS regions, where neurogenesis in the spinal cord occurs, is not consensual and the analogy with the brain is often unclear. In this review, we will try to describe the heterogeneity of the stem cell types in the spinal cord ependymal zone, based on their origin and stem cell potential. We will also consider specific animal in vitro models that could be useful to identify “the right” stem cell candidate for cell replacement therapies.
Flexibility in the perceptual span during reading: Evidence from Mongolian

Published: January 2020

Readers can acquire useful information from only a narrow region of text around each fixation (the perceptual span), which extends asymmetrically in the direction of reading. Studies with bilingual readers have additionally shown that this asymmetry reverses with changes in horizontal reading direction. However, little is known about the perceptual span’s flexibility following orthogonal (vertical vs. horizontal) changes in reading direction, because of the scarcity of vertical writing systems and because changes in reading direction often are confounded with text orientation. Accordingly, we assessed effects in a language (Mongolian) that avoids this confound, in which text is conventionally read vertically but can also be read horizontally. Sentences were presented normally or in a gaze-contingent paradigm in which a restricted region of text was displayed normally around each fixation and other text was degraded. The perceptual span effects on reading rates were similar in both reading directions. These findings therefore provide a unique (nonconfounded) demonstration of perceptual span flexibility.
Heaviness-brightness correspondence and stimulus-response compatibility
Authors: Walker Peter , Scallon Gabrielle , Francis Brian J
Published: January 2020

Cross-sensory correspondences can reflect crosstalk between aligned conceptual feature dimensions, though uncertainty remains regarding the identities of all the dimensions involved. It is unclear, for example, if heaviness contributes to correspondences separately from size. Taking steps to dissociate variations in heaviness from variations in size, the question was asked if a heaviness-brightness correspondence will induce a congruity effect during the speeded brightness classification of simple visual stimuli. Participants classified the stimuli according to whether they were brighter or darker than the mid-gray background against which they appeared. They registered their speeded decisions by manipulating (e.g., tapping) the object they were holding in either their left or right hand (e.g., left for bright, right for dark). With these two otherwise identical objects contrasting in their weight, stimuli were classified more quickly when the relative heaviness of the object needing to be manipulated corresponded with the brightness of the stimulus being classified (e.g., the heavier object for a darker stimulus). This novel congruity effect, in the guise of a stimulus-response (S-R) compatibility effect, was induced when heaviness was isolated as an enduring feature of the object needing to be manipulated. It was also undiminished when participants completed a concurrent verbal memory load task, countering claims that the heaviness-brightness correspondence is verbally mediated. Heaviness, alongside size, appears to contribute to cross-sensory correspondences in its own right and in a manner confirming the far-reaching influence of correspondences, extending here to the fluency with which people communicate simple ideas by manipulating a hand-held object.
Roll tilt self-motion direction discrimination training: First evidence for perceptual learning
Authors: Klaus Manuel P. , Schöne C. G. , Hartmann M. , Merfeld D. M. , Schubert M. C. , Mast F. W.
Published: January 2020

Perceptual learning, the ability to improve the sensitivity of sensory perception through training, has been shown to exist in all sensory systems but the vestibular system. A previous study found no improvement of passive self-motion thresholds in the dark after intense direction discrimination training of either yaw rotations (stimulating semicircular canals) or y-translation (stimulating otoliths). The goal of the present study was to investigate whether perceptual learning of self-motion in the dark would occur when there is a simultaneous otolith and semicircular canal input, as is the case with roll tilt motion stimuli. Blindfolded subjects (n = 10) trained on a direction discrimination task with 0.2-Hz roll tilt motion stimuli (9 h of training, 1,800 trials). Before and after training, motion thresholds were measured in the dark for the trained motion and for three transfer conditions. We found that roll tilt sensitivity in the 0.2-Hz roll tilt condition was increased (i.e., thresholds decreased) after training but not for controls who were not exposed to training. This is the first demonstration of perceptual learning of passive self-motion direction discrimination in the dark. The results have potential therapeutic relevance as 0.2-Hz roll thresholds have been associated with poor performance on a clinical balance test that has been linked to more than a fivefold increase in falls.
The impact of slippage on the data quality of head-worn eye trackers

Published: January 2020

Mobile head-worn eye trackers allow researchers to record eye-movement data as participants freely move around and interact with their surroundings. However, participant behavior may cause the eye tracker to slip on the participant’s head, potentially strongly affecting data quality. To investigate how this eye-tracker slippage affects data quality, we designed experiments in which participants mimic behaviors that can cause a mobile eye tracker to move. Specifically, we investigated data quality when participants speak, make facial expressions, and move the eye tracker. Four head-worn eye-tracking setups were used: (i) Tobii Pro Glasses 2 in 50 Hz mode, (ii) SMI Eye Tracking Glasses 2.0 60 Hz, (iii) Pupil-Labs’ Pupil in 3D mode, and (iv) Pupil-Labs’ Pupil with the Grip gaze estimation algorithm as implemented in the EyeRecToo software. Our results show that whereas gaze estimates of the Tobii and Grip remained stable when the eye tracker moved, the other systems exhibited significant errors (0.8–3.1∘increase in gaze deviation over baseline) even for the small amounts of glasses movement that occurred during the speech and facial expressions tasks. We conclude that some of the tested eye-tracking setups may not be suitable for investigating gaze behavior when high accuracy is required, such as during face-to-face interaction scenarios. We recommend that users of mobile head-worn eye trackers perform similar tests with their setups to become aware of its characteristics. This will enable researchers to design experiments that are robust to the limitations of their particular eye-tracking setup.
Synthesis of C-glycosyl phosphonate derivatives of 4-amino-4-deoxy-α-ʟ-arabinose
Authors: Kerner Lukáš , Kosma Paul
Published: January 2020

The incorporation of basic substituents into the structurally conserved domains of cell wall lipopolysaccharides has been identified as a major mechanism contributing to antimicrobial resistance of Gram-negative pathogenic bacteria. Inhibition of the corresponding enzymatic steps, specifically the transfer of 4-amino-4-deoxy-ʟ-arabinose, would thus restore the activity of cationic antimicrobial peptides and several antimicrobial drugs. C-glycosidically-linked phospholipid derivatives of 4-amino-4-deoxy-ʟ-arabinose have been prepared as hydrolytically stable and chain-shortened analogues of the native undecaprenyl donor. The C-phosphonate unit was installed via a Wittig reaction of benzyl-protected 1,5-arabinonic acid lactone with the lithium salt of dimethyl methylphosphonate followed by an elimination step of the resulting hemiketal, leading to the corresponding exo- and endo-glycal derivatives. The ensuing selective monodemethylation and hydrogenolysis of the benzyl groups and reduction of the 4-azido group gave the α-ʟ-anomeric arabino- and ribo-configured methyl phosphonate esters. In addition, the monomethyl phosphonate glycal intermediates were converted into n-octyl derivatives followed by subsequent selective removal of the methyl phosphonate ester group and hydrogenation to give the octylphosphono derivatives. These intermediates will be of value for their future conversion into transition state analogues as well as for the introduction of various lipid extensions at the anomeric phosphonate moiety.

The aim of this study is to investigate the effect of SCAMPER in improving creative imagination of 5-year-old children attending kindergarten. For this purpose, 49 children from the age group of 5 year attending a kindergarten in the Southwestern part of Turkey participated in the study. There were an experimental group and a control group in the study. SCAMPER technique was applied to the children in the experimental group. The control group continued to the normal education program. The data were collected by using Test of Creative Imagination (Child Form), which was developed by Aysun Gündoğan in 2019. At the end of the study, it was found that creative imagination levels of the children in the experimental group receiving education with SCAMPER technique increased. Differences among children receiving SCAMPER education were found in the fluency sub-dimension of creativity. The SCAMPER technique was effective in improving the creative imagination. Therefore, techniques and activities that enable the development of creative imagination should be applied to individuals from an early age.

We present the first spatially resolved scattered-light images of four debris disks around members of the Scorpius-Centaurus (Sco-Cen) OB association with high-contrast imaging and polarimetry using the Gemini Planet Imager (GPI). All four disks are resolved for the first time in polarized light, and one disk is also detected in total intensity. The three disks imaged around HD 111161, HD 143675, and HD 145560 are symmetric in both morphology and brightness distribution. The three systems span a range of inclinations and radial extents. The disk imaged around HD 98363 shows indications of asymmetries in morphology and brightness distribution, with some structural similarities to the HD 106906 planet–disk system. Uniquely, HD 98363 has a wide comoving stellar companion, Wray 15-788, with a recently resolved disk with very different morphological properties. HD 98363 A/B is the first binary debris disk system with two spatially resolved disks. All four targets have been observed with ALMA, and their continuum fluxes range from one nondetection to one of the brightest disks in the region. With the new results, a total of 15 A/F stars in Sco-Cen have resolved scattered-light debris disks, and approximately half of these systems exhibit some form of asymmetry. Combining the GPI disk structure results with information from the literature on millimeter fluxes and imaged planets reveals a diversity of disk properties in this young population. Overall, the four newly resolved disks contribute to the census of disk structures measured around A/F stars at this important stage in the development of planetary systems.

Published: January 2020

BACKGROUND: Annona muricata (Soursop) has an antimicrobial activity toward various pathogenic microorganisms which support its ethnomedicinal for the treatment of many infectious diseases.
AIM: Aim of the present study to evaluate the relation between antimicrobial activities of terpenoids extracted from different soursop parts with the isolated endophytic fungi.
METHODS: Endophytic fungal species of pulp and peel of Annona fruit along with those of seeds were isolated. Salkowski test was used for qualitative screening of terpenoids in plant and the isolated endophytic Aspergillus niger strain SH3.
RESULTS: Endophytic A. niger strain SH3 and Annona seed extract showed high terpenoid content indicated by the high intensity of reddish-brown colour. GC/Mass analysis revealed six compounds of terpenoids from endophytic A. niger strain SH3 extract and four compounds from seed extract with different retention times. The antimicrobial assay was performed using A. niger strain SH3 extract and Annona seed extract singly or in combinations against S. aureus, P. aeruginosa, E. coli and C. albicans.
CONCLUSION: The results revealed the significant antimicrobial activity of both extracts. However, the combined extract showed some reduction in antimicrobial activity which could be attributed to the antagonistic effect exhibited by their constituents.
A National Survey of Educational and Training Preferences and Practices for Public Health Nurses in Canada
Authors: Sibbald Shannon , Jegatheeswaran Jathuson , Pocock Hayley , Penney Greg
Published: January 2020

Background:

The effective mix of public health professionals has been the focus of recent policies and literature. Information is limited on the preferences for training and continuing education of the Canadian Public Health Workforce. This information could assist in surge capacity efforts and help in evaluating the success of workforce development strategies and recruitment/retention efforts.

Method:

The Canadian Public Health Workforce Survey was conducted in 2015 by the Canadian Public Health Association in collaboration with the Public Health Agency of Canada (PHAC). The survey was conducted to inform an ongoing evaluation of the PHAC's workforce development. This article reports on a subset of the survey: public health nurses (PHNs).

Results:

The response rate to the survey was approximately 40% (2,075 participants); 470 respondents (22.7%) were PHNs. Challenges faced by PHNs to pursuing continuing education include a lack of targeted training, resources, and coordinated training efforts.

Conclusion:

The results provide insight into potential direction to support the work of PHNs in practice including a need for a coordinated approach to continuing education. Future educational strategies should consider tailored education strategies for PHNs.

Acute Care Nurses' Arrhythmia Knowledge: Defining Competency
Authors: Keller Kathryn , Eggenberger Terry , Leavitt Mary Ann , Sabatino Denese
Published: January 2020

Background:

Most methods of evaluating arrhythmia knowledge acquisition are internally developed by nursing professional development practitioners and are institution specific. This approach has resulted in assessing nurses' minimal qualifications for rhythm recognition as defined by the facility but does not result in describing basic, intermediate, and advanced competency levels for practice.

Method:

This quantitative study with a convenience sample of 85 acute care nurses refined an instrument to assess varying levels of arrhythmia recognition competency for acute care nurses.

Results:

The final instrument, called the Cardiac Arrhythmia Recognition Tool (CART), consisted of 33 items divided into basic, intermediate, and advanced subscales, with an overall Cronbach's alpha of .84.

Conclusion:

This study significantly contributes to defining arrhythmia competency in nurses caring for electrocardiographically monitored patients.

Identifying and Bridging the Gaps in Antimicrobial Stewardship in Post-Acute and Long-Term Care
Authors: Fornaro Rachyl , Heil Emily , Claeys Kimberly , Sheikh Fatima , Naqvi Fatima , Chou Joshua , Oketch Ednner , Mansour Daniel , Zarowitz Barbara , Brandt Nicole
Published: January 2020

National organizations have developed guidelines and tools for antimicrobial stewardship (AMS) in post-acute and long-term care (PALTC), but there is a need to effectively translate these into actionable, measurable, and impactful programs. An electronic needs assessment survey was developed and distributed to health care providers and administrators involved with AMS activities in PALTC facilities in Maryland. The results of this survey were used to develop a statewide initiative to improve AMS in nursing facilities. The survey revealed that barriers to implementing AMS include limited access or poor utilization of experts in AMS and infectious disease, adverse event data collection tools, and locally developed protocols and guidelines. Strategies to improve AMS included the provision of free continuing education to a multidisciplinary audience and improved access to individuals with expertise in infectious disease and the development of an adverse drug event tool. Continuing to provide meaningful tools and resources that address the specific needs of nursing facilities should lead to improved compliance with regulations and ultimately improved resident outcomes.

Epidemiology of Osteoarthritis
Authors: D'Ambrosia Robert D
Published: January 2020

abstract

The majority of adults >55 years of age show radiographic evidence of osteoarthritis; however, determining definitive prevalence and incidence rates of knee osteoarthritis and hip osteoarthritis poses methodologic problems. Several factors play a role in osteoarthritis risk, including age, gender, genetics, behavioral influences, and ethnicity. Studies cited compare data from the Framingham Osteoarthritis Study with data from studies performed in Asian and European populations. A number of broad trends stand out, including higher prevalence in advanced age for both hip and knee osteoarthritis, with higher prevalence and incidence in women than in men.
Etiology and Pathophysiology of Osteoarthritis
Authors: Mandelbaum Bert , Waddell David
Published: January 2020

abstract

Acute or chronic insult, including normal wear and tear, age, obesity, and joint injury, may initiate an imbalance between matrix synthesis and matrix degradation in healthy cartilage that promotes chondral loss and prevents cartilage self-repair. The structure of healthy cartilage and the pathophysiological mechanisms of its degradation are described, followed by descriptions of endogenous and exogenous factors believed to be involved in the progressive course of osteoarthritis. Studies cited include research from the community of sports medicine.

abstract

Sacrectomy is intended to resect aggressive local and life-threatening disease. Reconstruction can be difficult. This article reports on the use of sacrectomy for tumor and tumor-like conditions. Procedures included 9 partial, 7 subtotal, 7 hemi-, and 4 total sacrectomies. Of 22 patients with primary malignant disease, 64% were alive without evidence of disease. The local recurrence rate was 27%. Thirty-two percent developed metastatic disease and 32% died from progressive disease. The complication rate was 33%. Tumor control was achieved in 73%. Postoperative complications occurred in 33%. Sacral resection remains a challenging operation.
