Effect of Education Program on Thermal care of Pregnant Adolescents Attending Antenatal Clinic at Primary Healthcare Centers in Zaria Metropolis, Nigeria
No full text<p>Hypothermia is known to be a major cause of neonatal mortality as it complicates other conditions like asphyxia, prematurity <br>at early neonatal period. Pregnant adolescents are at high risk of having preterm birth, low-birth-weight babies and sub optimal <br>thermal care practices. The study aimed to evaluate the effect of nursing intervention program on thermal care of pregnant <br>adolescents attending antenatal clinic in Zaria metropolis. It a quasi-experimental design using a multistage sampling <br>technique to obtain data from 302 adolescent mothers; assigned to the study and control groups; 151 participants to each <br>group. Data were collected using structured and validated interviewer-administered questionnaire and observation checklist <br>before and after the intervention. Descriptive statistics of mean and standard deviation were presented on <br>frequency/percentage tables while inferential statistics was used in the form of chi-square and t-test to evaluate the effect and <br>the trends of the effect. At pretest, no statistically significant difference in the pretest mean knowledge (p-value = 0.504) <br>scores of mothers between the study and control groups. At post-tests, the mean knowledge and practice scores of mothers in <br>study group improved significantly (P value < 0.05) at first week, 6th week, 10th week, 14th week and 6th month postpartum. <br>Mothers in intervention group were more satisfied with their role of thermal care than those in control group (p-value <0.001). <br>Hence the need for nurses and midwives to continue training pregnant adolescents on thermal care.</p>
Perception of Patients Towards Nurses’ Attitudes: Implication on the Public Image of Nursing
No full textBackground: The negative public image of Nurses is not in agreement with the important work they do. There is therefore a need to investigate what attracted this negative image to Nurses.
Aim: The study aims to investigate patients’ perception of nurses’ attitudes and how that impact on their perception of the public image of nurses
Method: A cross-sectional descriptive design was used to select 380 patients attending clinics/admitted in the wards in a tertiary hospital, Zaria systematically. The ensuing data was subjected to rigorous quantitative analysis with the aid of Statistical Package for the Social Sciences (SPSS) version 25.0.
Result: While the majority of the respondents were of the opinion that nurses are not friendly or tend to shout at them (166 or 51.4% and 165 or 51% respectively), the majority were also of the view that the nurses were competent and efficient in professional service delivery such as; administering the medication on time (117 or 87%, n=134), doing the necessary temperature checks (239 or 74%, n=323), and overall dedication to duty (294 or 91%, n=323).
Conclusion: Patients have negative perceptions towards nurses’ attitudes as such; nurses need to work on their social skills and attitudes in order to complement their technical competence as a way of improving patient perception and public image. Among the recommendations for achieving this are training of nurses on positive attitude and stress management, formal recognition of friendly Nurses, and wearing of name tags to easy identified by patients.

The argument for an exomoon hinges on the system being relatively close to the Sun. The data constrain the product MLπrel where ML is the lens system mass and πrel is the lens-source relative parallax. If the lens system is nearby (large πrel), then ML is small (a few Jupiter masses) and the companion is a sub-Earth-mass exomoon. The best-fit solution has a large lens-source relative proper motion, μrel = 19.6 ± 1.6 mas yr–1, which would rule out a distant lens system unless the source star has an unusually high proper motion. However, data from the OGLE collaboration nearly rule out a high source proper motion, so the exoplanet+exomoon model is the favored interpretation for the best fit model. However, there is an alternate solution that has a lower proper motion and fits the data almost as well. This solution is compatible with a distant (so stellar) host. A Bayesian analysis does not favor the exoplanet+exomoon interpretation, so Occam's razor favors a lens system in the bulge with host and companion masses of M host = 0.12 +0.19-0.06 MΘ and mcomp = 18+28-10M⊕, at a projected separation of a⊥ = 0.84+0.25−0.14 AU. The existence of this degeneracy is an unlucky accident, so current microlensing experiments are in principle sensitive to exomoons. In some circumstances, it will be possible to definitively establish the mass of such lens systems through the microlensing parallax effect. Future experiments will be sensitive to less extreme exomoons.Peer reviewe

Organic Solar Cell Performance of Musa acuminata bracts Extract by Microwave Irradiation Treatment
No full textThe purpose of this study is to fabricate DSSC which performs well from natu-
ral pigments by giving exposure to microwave irradiation in materials to
increase pigment uptake. In this research, the microwave irradiation was
applied in coating banana flower extract (Musa acuminata bract) on the elec-
trode, to increase light absorption of anthocyanin pigment. It is expected that
the device can absorb more solar energy. The banana flower extract was char-
acterized using Ocean Optic Vis-Nir USB 4000 to observe the optical proper-
ties. The irradiation treatment was carried out using Electrolux Microwave
(EMM 2308X) at power 150 W. The DSSC samples were characterized using
I-V meter Nacrieble 101. The maximum absorbance of 1.55 a.u. is found for
the mass fraction of 0.45. The microwave irradiated device has an efficiency of
about 3.69×10−6
%, whereas which is no microwave irradiation has a maximum
efficiency of about 0.57%. It shows that microwave irradiation can improve
DSSC performance. The banana flower extract is available as an alternative
organic photosensitizer in the fabrication of DSSC
Properties of Th4+ and Th3+ from rf spectroscopy of high-L thorium Rydberg ions
No full text2013 Summer.Includes bibliographical references.Several properties of radon-like Th4+ and francium-like Th3+ were determined from measurements of high-L Rydberg fine structure in Th3+ and Th2+ ions. The measurements were carried out using the resonant excitation Stark ionization spectroscopy (RESIS) technique to detect rf transitions between levels in the same n. The measured Rydberg fine structures were then fit to an effective potential model, and the properties of the ions were extracted. Properties of the 1S0 ground state of Th4+ extracted from the measurements of the n=37 Th3+ Rydberg fine structure were the scalar dipole polarizability, αD,0=7.702(6)a.u. and the scalar quadrupole polarizability, αQ,0=29.1(1.6)a.u.. The Th2+ Rydberg fine structure is much more complex since the ground state of Th3+ is a 2F5/2, and the presence of low-lying excited states cause non-adiabatic effects in the fine structure which are not well described by the effective potential. To extract the properties, non-adiabatic corrections had to be calculated. The properties of Th3+ extracted were the permanent quadrupole moment, Q=0.5931(14)a.u., the scalar and tensor dipole polarizabilities, αD,0=15.224(33)a.u. and αD,2=-5.30(11)a.u., the permanent hexadecapole moment, Π=-0.69(28)a.u., and the reduced dipole and octupole matrix elements coupling the ground state to the 6d 2D3/2 state, ||=1.436(2)a.u. and ||=3.3(1.1)a.u.
Van Leegstand tot Leefbaar: Het organiseren van het proces van de transformatie van leegstaand vastgoed naar tijdelijke studentenhuisvesting
No full textIn de toekomst zal de vraag naar nieuwbouw afnemen en zal er juist steeds meer van de bestaande voorraad getransformeerd dienen te worden. Bovendien zullen veel bestaande gebieden geherstructu-reerd worden om deze gebieden leefbaarder te maken. Hierbij kan tijdelijke transformatie een grote rol spelen. Vaak duurt het erg lang voordat - na het initiatief om een gebied te transformeren – het gebied daadwerkelijk wordt getransformeerd. Als er in de tussentijd niets met de gebouwen in dit gebied gebeurt blijven gebouwen leegstaan en blijft het gebied onleefbaar. Hier ligt een grote kans om twee problemen; het tekort aan studentenkamers en deze tijdelijke leegstand, op te lossen. Stichting Herontwikkeling tot Studentenhuisvesting Delft (SHS Delft) heeft deze kans gezien en wil deze problemen oplossen. SHS Delft is een stichting die bestaat uit studenten van de Technische Uni-versiteit Delft. SHS Delft wil graag panden transformeren naar tijdelijke woonruimte voor studenten en deze panden vervolgens zelf beheren. In Utrecht is eerder een dergelijke stichting opgericht (Stichting Tijdelijk Wonen Utrecht) die al enkele panden tijdelijk heeft getransformeerd naar studentenhuisves-ting. Toch is het voor zulke beginnende stichtingen als SHS Delft lastig om duidelijk te krijgen wat ze moeten doen en vooral hoe ze dat moeten doen. Het kost voor de stichting erg veel tijd om er achter te komen hoe ze het aan moeten pakken. Daarnaast zullen ze veel van wat STW ook al heeft uitge-zocht opnieuw moeten uitzoeken, omdat er nog geen duidelijke informatie op papier is verzameld. Vandaar dat SHS Delft naar de TU Delft toe is gestapt met de vraag hoe ze het aan moeten pakken, waar ze moeten beginnen en hoe ze problemen waar ze tegenaan lopen het beste op kunnen lossen. Op dit moment is er duidelijk een gebrek aan kennis op het gebied van het gehele proces (vanaf het initiatief tot en met beheer) van tijdelijke transformatie van leegstaand vastgoed naar studentenhuis-vesting. Groepen die zich bezighouden met studentenhuisvesting gaan los van elkaar aan de slag en moeten steeds opnieuw het wiel uitvinden. Daarom wordt in dit onderzoek de vraag gesteld: Hoe kan het proces van de transformatie van leegstaand vastgoed naar tijdelijke studenten-huisvesting in Nederland worden georganiseerd van de initiatieffase tot en met de beheersfase? Het doel van dit onderzoek is tweeledig: het richt zich enerzijds op uitbreiding van de kennis over tij-delijke transformatie en richt zich anderzijds op het ontwikkelen van een handleiding voor de trans-formatie van leegstaand vastgoed naar studentenhuisvesting. Deze handleiding kunnen studenten huisvestingsstichtingen en andere ontwikkelaars van studentenhuisvesting gebruiken wanneer ze leeg-staande panden willen transformeren naar tijdelijke studentenhuisvesting.Design and Construction ManagementReal Estate & HousingArchitectur
Localized surface plasmon resonance sensor based on gold-coated tapered optical fiber for refractive index measurement
No full textThe tapered optical fiber (TOF) sensor based on localized surface plasmon resonance (LSPR) was experimentally demonstrated for determination of surrounding liquid refractive index (RI) changes. The reduction of tapered waist diameter was done by flame-brushing method which results in the diameter range of 6 μm to 18 μm. The sensing mechanism is based on the transmission shift in the monitored output spectra. Key parameter optimization of the TOF sensor has been investigated particularly on the coating time of gold nanoparticles (AuNPs) onto fiber substrate. Functionalization of AuNPs by self-assemble monolayer was carried out through dip coating technique. Five different coating periods of 24, 48, 72, 96 and 120 hours have been performed on the TOF and characterized by using field emission scanning electron microscopy (FESEM). Histogram analysis was extracted from the FESEM images in order to determine the average particle’s size while the coating thickness were measured based on the cross-section image analysis. The highest sensitivity of the sensor was recorded at 18.49314 nm/RI corresponding to 48 hours of coating time. The optimum thickness of coating layer was calculated around 53.11 nm along the average particle’s size of 15 nm. Energy dispersive X-ray (EDX) characterization shows 22.4% of gold element on deposited fiber surface which proved the existence of the gold on the tapered structure. The optimized sensor was further examined for its overall performance in terms of stability, reversibility and repeatability over RI range from 1.3324 to 1.4254. Stability test of the TOF sensor suggests that the output signals are stable at low and medium of RI but a little variation on highest RI was recorded around ±0.00594 a.u. For the reversibility check, the TOF sensor acquired good response with little variation of ±0.008 a.u. between ascending and descending measurement order
