Between Religion and Education in Freud Perspective
This study focuses on religion and Education process of the internalization of democratic values, which are universal in nature and on ways to look at the nature of this process in detail. In addition, this study also focuses on the relevance of the internalization of the values to the Islamic education development. Researchers used a rationalistic approach (that is the opposite of the philosophy of rationalism thinking and not simply think using the ratio), which is a qualitative research approach that emphasizes the rationalistic thinking patterns. The results showed that Freud apply ideas in family and social life. His idea also offers guidance for explanations of myths, fairy tales, and history. Then interpret the drama, literature, and art. He is always looking for new dimensions and wider application of the ideas anyway, i.e., unconscious, Oedipus complex, a mental disorder (neurosis) and three basic framework of human personality. Towards the end of life, he thought of the themes of death, human limitations and the boundaries of civilization. Although he lived in difficult times which lie between the two world wars, his commitment to psychology remains high, this proves his confidence over the progress of science
Anaerobic digestion of cattle manure: influence of inoculum concentration
This study evaluated the performance of anaerobic treatment of cattle manure (CM) with palm oil mill effluent (POME) inoculum in terms of biogas production and volatile solid (VS) reduction. The objective of the study was to determine the effect of substrate to (POME) ratio used as inoculum on digester performance. The study was conducted in a 10-L lab-scale bioreactor operated at thermophilic (53oC) temperature. The result from the study showed that anaerobic digestion of cattle manure with POME inoculum can be done successfully in batch and semi-continuous mode. Biogas production was observed to commence immediately and the POME inoculum shown a strong influence on the initial biogas production rate. Average biogas yield was estimated to be about 0.346 and 0.299 m3 kg-1 VS added for the CM(5) : POME(1.5) and CM(5) : POME(1) respectively. However, nearly similar chemical oxygen demand (COD) removal of 33% and 30% with volatile solids (VS) removal of 58.6% and 52% for the CM(5):P0ME(1.5) and CM(5):POME(1), respectively was achieved. These results are hopeful for the treatment of cattle wastes and POME mass available in Malaysia
SWAT SUBBASINS PARAMETERS AND FLOOD RISK SIMULATIONS USING 3D IN TERENGGANU WATERSHED
Flood is one of the natural disasters that occurs mostly due to climate characteristics and locations. The application
of SWAT has categorized the subbasins and identify them on the basis of parameters. The use of GIS technology
produces the flood risk zone through the 3D ArcScene 10.3. the ArcGIS 10.3 and ArcSWAT 2012 were employed for
the analysis of the result. The remote sensing data from ASTER DEM was also been used for providing the highresolution platform. One of the significance of this study is the identification of 25 different sub-basins with their
individual parameters that make easiear to classify and explore. The 3Dsimulation produces different categories of
flood risk zone from very high vulnerability of flood to no flood risk zone. All these are confined within the 25
subbasins parameters obtained from the catchment area of Terengganu. The model designed in this study is clearly
going to be useful for planning as well as management not only in Terengganu but entire Malaysia or similar
environment
Design of an Anaerobic Digester for Generation of Biogas Fired in a Burner and Lamp
This work presents design of an anaerobic digester for generation of biogas fired in a burner and in a gas mantle lamp. The methodology utilized equations to describe digester that stores slurry and biogas which were discharged according to designed orifices over a period. Models to predict volume of biogas generation over a period of retention, spent slurry discharge height from cylindrical digester to expansion chamber as well as energy delivered to the biogas burner and lamp were developed to promote scale and dimensions of digester systems. The anaerobic digester was determined to have a total plant volume of 10.5 m3. The volume of biogas generated over a period of 42 days retention shows a concave down curve of exponential polynomial equation, with highest rated daily gas production of about 5 m3 occurring between 15-25 days. The spent slurry flows towards expansion chamber as slurry level decreases in the digester and became much pronounced in day 15 of 42 days retention. The burner had specific firing rate of 0.256 m3/s/m2 and heat output per unit port area of 677 W/cm2 while the lamp light output was 1267 lm for an illumination area of 11.3 m2. The cumulative heat load of the burner and lamp reaches about 9.0 kW and 2.0 kW, respectively.Keywords: Anaerobic Digester; Biogas; Burner; Lamp; Model
The Effectiveness of Utilising the Building Information Modelling Based Tools for Safety Training and Job Hazard İdentification
The fields of architecture, engineering and construction (AEC) have kept pace with recent technological developments in design and construction. However, it is difficult to obtain information on the breadth of applications of BIM -based tools throughout the life cycle of construction projects. Hence, this study attempts to empirically identify and evaluate the applications of pre-construction tools, with a focus on safety training and workplace hazard recognition. A questionnaire in the form of a survey was used to collect data. The results show that the ten predictors account for 52.3% of the variation in BIM knowledge (F (10, 56) = 6.133, p < 0.001). It is also found that site analysis and safety instructions have no effect on the measured variable. The study represented a comprehensive blend of research to improve the use of BIM -based tools for safety training and workplace hazard identification. It also contributed to the knowledge of how to use BIM -based tools in the pre-construction phase. The development of the BIM -process flow framework for safety training and hazard identification will be the main focus of future work
Outbreak of Fatal Childhood Lead Poisoning Related to Artisanal Gold Mining in Northwestern Nigeria, 2010.
Background: In May 2010, a team of national and international organizations was assembled to investigate children's deaths due to lead poisoning in villages in northwestern Nigeria. Objectives: To determine the cause of the childhood lead poisoning outbreak, investigate risk factors for child mortality, and identify children aged <5 years in need of emergency chelation therapy for lead poisoning. Methods: We administered a cross-sectional, door-to-door questionnaire in two affected villages, collected blood from children aged 2-59 months, and soil samples from family compounds. Descriptive and bivariate analyses were performed with survey, blood-lead, and environmental data. Multivariate logistic regression techniques were used to determine risk factors for childhood mortality. Results: We surveyed 119 family compounds. One hundred eighteen of 463 (25%) children aged <5 years had died in the last year. We tested 59% (204/345) of children, aged <5 years, and all were lead poisoned (≥10 µg/dL); 97% (198/204) of children had blood-lead levels ≥45 µg/dL, the threshold for initiating chelation therapy. Gold ore was processed inside two-thirds of the family compounds surveyed. In multivariate modeling significant risk factors for death in the previous year from suspected lead poisoning included: the child's age, the mother performing ore-processing activities, community well as primary water source, and the soil-lead concentration in the compound. Conclusion: The high levels of environmental contamination, percentage of children aged <5 years with elevated blood-lead levels (97%, >45 µg/dL), and incidence of convulsions among children prior to death (82%) suggest that most of the recent childhood deaths in the two surveyed villages were caused by acute lead poisoning from gold ore-processing activities. Control measures included environmental remediation, chelation therapy, public health education, and control of mining activities
Combined QCD and electroweak analysis of HERA data
A simultaneous fit of parton distribution functions (PDFs) and electroweak
parameters to HERA data on deep inelastic scattering is presented. The input
data are the neutral current and charged current inclusive cross sections which
were previously used in the QCD analysis leading to the HERAPDF2.0 PDFs. In
addition, the polarisation of the electron beam was taken into account for the
ZEUS data recorded between 2004 and 2007. Results on the vector and
axial-vector couplings of the Z boson to u- and d-type quarks, on the value of
the electroweak mixing angle and the mass of the W boson are presented. The
values obtained for the electroweak parameters are in agreement with Standard
Model predictions.Comment: 32 pages, 10 figures, accepted by Phys. Rev. D. Small corrections

Limits on the effective quark radius from inclusive scattering at HERA
The high-precision HERA data allows searches up to TeV scales for Beyond the
Standard Model contributions to electron-quark scattering. Combined
measurements of the inclusive deep inelastic cross sections in neutral and
charged current scattering corresponding to a luminosity of around 1
fb have been used in this analysis. A new approach to the beyond the
Standard Model analysis of the inclusive data is presented; simultaneous
fits of parton distribution functions together with contributions of "new
physics" processes were performed. Results are presented considering a finite
radius of quarks within the quark form-factor model. The resulting 95% C.L.
upper limit on the effective quark radius is cm.Comment: 10 pages, 4 figures, accepted by Phys. Lett.
Search for a narrow baryonic state decaying to and in deep inelastic scattering at HERA
A search for a narrow baryonic state in the and
system has been performed in collisions at HERA with the ZEUS detector
using an integrated luminosity of 358 pb taken in 2003-2007. The search
was performed with deep inelastic scattering events at an centre-of-mass
energy of 318 GeV for exchanged photon virtuality, , between 20 and 100
. Contrary to evidence presented for such a state around 1.52
GeV in a previous ZEUS analysis using a sample of 121 pb taken in
1996-2000, no resonance peak was found in the invariant-mass
distribution in the range 1.45-1.7 GeV. Upper limits on the production cross
section are set.Comment: 16 pages, 4 figures, accepted by Phys. Lett. B. Minor changes from
