Opis:
This project was conducted with a multicultural construction company in Hawaii, USA. The job duties performed included drywall and carpentry work. The following objectives were selected for this project: (a) fire prevention training and inspection of first aid equipment; (b) blood-borne pathogen training and risk evaluation; (c) ergonomic and risk evaluation intervention program; (d) electrical safety training and inspection program; (e) slips, trips, and falls safety training; (f) stress assessment and Personal Profile System; (g) safety and health program survey; (h) improving employee relations and morale by emphasizing spirituality; and (i) computer-assisted biofeedback stress management training. Results of the project indicated that observed safety hazards, reported injuries, and levels of perceived stress were reduced for the majority of the population.

Opis:
The drastic increase in the emission of CO2 (carbon dioxide) during the last 30 years caused by fossil fuel combustion has been identified as the major reason for the climate change. Demand for fossil fuels has begun to decline in the developed world, however, demand in developing countries has been rising and will continue to rise. India in its developing phase has been risen as one of the major emitting nations since they hugely rely on fossil fuels. And opting alternate energy sources wouldn’t suffice for meeting the obligatory values of emission. While the global frameworks for climate change demands for limiting the temperature rise within 2 °C, more mitigation technologies other than renewable energy and energy efficiency are searched for, where Carbon Capture & Sequestration pitch in. In this paper we discuss about the capacity of CCS as a climate mitigation tool and additionally evaluates the feasibility of implementation in Indian market.

Opis:
The nonlinear response of rock is much different than that of ordinary materials. Especially at ambient conditions, rock responds in an extremely nonlinear fashion, often due to the presence of hysteresis. Nonlinear elastic response in rock is illustrated by dynamic results from resonant bar and pulse-mode experiments.

Opis:
Electronic states of 4f samarium ions were investigated by photoemission spectroscopy in samarium-rich CdSmTe sample obtained by MBE. The photon energy of synchrotron radiation allowed to investigate Fano-type resonance and antiresonance. The energy distribution curve spectra were attributed to the Sm 4d-4f transition. The shape of the constant initial states spectra was compared with this one obtained for atomic samarium.

Opis:
This paper reports the synthesis, crystal structure, surface morphology, optical and electrical properties of Mg-doped Sn₂S₃ thin films deposited by spray pyrolysis technique. All the films exhibit orthorhombic crystal structure with a (211) preferential orientation. Crystallite size calculations based on the Debye-Scherrer formula indicated that the Sn₂S₃ crystallite size increases with Mg content from 27.97 nm to 33.58 nm. Scanning electron microscopy images showed that all the films were very smooth composed of nanoneedle and nanoplate shaped grains. The band gap energy of the films exhibits a blue shift from 1.94 eV to 2.09 eV with increase in Mg concentration. Resistivity values of the undoped and Mg-doped Sn₂S₃ films were found to be in the order of 0.1 Ωcm. From the obtained results it is observed that the Sn₂S₃ film coated with 2 wt% Mg concentration exhibits better physical properties.

Resonant photoemission spectroscopy was applied to determine the Mn 3d derived contribution to the valence band density of states of Mn$\text{}_{0.44}$ Mg$\text{}_{0.56}$Te grown by molecular beam epitaxy on a GaAs(001) substrate. The modifications of the valence band density-of-states distribution are discussed as a consequence of the substitution of Mg ions for Mn ions.

Opis:
The electronic band structure of Mn/ZnTe(110) (1×1) has been studied by angle-resolved photoelectron spectroscopy. The sets of spectra were acquired for the clean surface and after in situ deposition of 0.4 ML of Mn, in order to compare the band structures and to reveal changes brought about by the presence of Mn. The experimental band structure diagram of Mn/ZnTe along theΓ-K direction in the Brillouin zone has been derived from the experimental data. Indications of interaction between the Mn 3d states and sp$\text{}^{3}$ bands of the semiconductor are discussed.

Opis:
We report a new approach to investigate metal-semiconductor interface formation. Photoemission spectroscopy was applied in order to investigate the clean surface of a Sn$\text{}_{0.97}$Cr$\text{}_{0.03}$ Te crystal and to observe its changes under sequential deposition of small amounts of Cr atoms. In order to analyse the Cr 3d contribution to the valence band, the Fano-type resonance tuned to the Cr 3p-3d transition was used. The experiment was designed to follow the Sn$\text{}_{0.97}$Cr$\text{}_{0.03}$ Te/Cr interface formation process. At the clean Sn$\text{}_{0.97}$Cr$\text{}_{0.03}$Te surface, the Cr 3d states contribution to the valence band was found to be positioned 0.8 eV below the Fermi level. After the Cr deposition processes the contribution shifted to a higher binding energy and another contribution 5.8 eV below the Fermi level was also observed.

Opis:
This study was conducted to investigate the attitude of adolescent students towards sex education. The investigation was carried out in Junior Secondary Schools in Gwagwalada Area Council, Federal Capital Territory, Abuja. A simple random technique was used to select the sample size of 1,981 respondents, made up of students in three (3) schools within Gwagwalada Area Council, used for the study. The statistical analysis used for data presentation and analysis were frequency table and percentages. The findings indicated that adolescent students held generally positive attitudes towards sexuality education, with female holding more positive attitudes than male. Learners indicated that the sexuality programme provide valuable information especially with regards to their own bodies and self-respect. Recommendations were given, among which include, that; parents should support their adolescent to practice the knowledge acquired from sex education, ideal (positive) peer group should be form by adolescents, including the society encouraging adolescents to practice teachings of sexuality education, and presenting values and morals that the adolescents can emulate as a guide regarding sexuality issues.

Opis:
Photoemission measurements using synchrotron radiation were performed on PbYbTe (bulk crystal) and CdYbTe (MBE thin film). The resonant enhancement of the photoemission was applied for investigation of the contribution of Yb 4f electrons to the valence band. The set of the energy distribution curves was collected for energies in the region close to the 4d-4f Fano transition. The Yb 4f$\text{}^{14}$ were observed at the binding energies close to the edge of the valence band while the 4f$\text{}^{13}$ states were revealed deep in the valence band.
