Towards Divine Economics: Some Testable Propositions
No full textThroughout the human history, the religion has remained a fundamental feature of social construct and human behaviour. Religious orientation plays important role in shaping human perceptions about economic and non-economic activities. With few exceptions, religion has remained an un-explored area in economics. For most economists, narrative and metaphor have no place in a rational choice theory, which is a wrong belief. In fact, any approach that considers behavioural laws satisfying the criteria of objectivity, reproducibility, and refutability is scientific and falls in purview of rational choice framework. A few studies, however, do exist on economics of religion under rational choice concerning to households, groups, and entire “religious markets”. [Becker (1976); Iannaccone (1988, 1990, 1992, 1993); Mack and Leigland (1992)]. Rosenberg (1985) presents discussion of the limitations of neoclassical economic theory due to its reliance on exogenous differences in taste and preference. It is argued that these limitations cannot be circumvented by findings and theories in other disciplines (e.g., psychology), because any measurement of preferences must begin with neoclassical assumptions about rationality. The alternative to tasteendogeniety advanced by [Becker (1976)] is found to only circumvent the usual difficulties if “stable preferences” notion is interpreted as needs. Further advancement is not taking place because of the important heterogeneous variables, which have yet received little attention from economists. Such variables may be found in attitudes and values acquired by consumers in variety of social and religious environments.
Critical Analysis of Islamic Education Leadership Based on the Trem and Ideal Leadership Characteristics (Leadership Practice KH Hamdani Abu Bakran Adz-Zakiy)
No full textThis paper is intended to reveal the basic theories of Islamic educational leadership. From the definition of Islamic education leadership, the ideal terms and characteristics as a leader of Islamic education. The characteristics and conditions of leadership Islamic education have been applied in the KH Hamdani Abu Bakran Adz-zakiy leadership in Raudatul Muttaqin Islamic boarding school. He is a preacher and Islamic boarding school leader capable of influencing positive changes to his students. KH Hamdani explains the term as a leader must be able to influence others, must have strong integrity, and an ability to problem-solving. The characteristic of an Islamic Education Leader is Kharisma. The author wanted the leadership of Islamic education (except Islamic boarding school) can use the culture of the terms and characteristics of Islamic boarding school leadership, especially that has been applied by KH Hamdani Abu Bakran Adz-zakiy leadership. The results showed that the ideal Islamic leadership has been applied by KH Hamdani. This leadership can be a role model and practiced at the same time by other Islamic educational institutions, such as madrasa. So as the leadership of Islamic education is not only labeled Islam but it really implements the true Islamic leadership

Unravelling H chemisorption and physisorption on metal decorated graphene using quantum Monte Carlo
No full textMolecular hydrogen is at the core of hydrogen energy applications and has the
potential to significantly reduce the use of carbon dioxide emitting energy
processes. However, hydrogen gas storage is a major bottleneck for its
large-scale use as current storage methods are energy intensive. Among
different storage methods, physisorbing molecular hydrogen at ambient pressure
and temperatures is a promising alternative - particularly thanks to tuneable
lightweight nanomaterials and high throughput screening methods. Nonetheless,
understanding hydrogen adsorption in well-defined nanomaterials remains
experimentally challenging and reference information is scarce despite the
proliferation of works predicting hydrogen adsorption. In this work, we focus
on Li, Na, Ca, and K, decorated graphene sheets as substrates for hydrogen
adsorption and compute the most accurate adsorption energies available to date
using quantum diffusion Monte Carlo (DMC). Building on our previous insights at
the density functional theory (DFT) level, we find that a weak covalent
chemisorption of molecular hydrogen, known as Kubas binding, is feasible on Ca
decorated graphene according to DMC, in agreement with DFT. This finding is in
contrast to previous DMC predictions of the 4H/Ca gas cluster where
chemisorption is not favoured. However, we find that the adsorption energy of
hydrogen on metal decorated graphene according to a widely-used DFT method is
not fully consistent with DMC and the discrepancies are not systematic. The
reference adsorption energies reported herein can be used to find better
work-horse methods for application in large-scale modelling of hydrogen
adsorption. Furthermore, the implications of this work affect strategies for
finding suitable hydrogen storage materials and high-throughput methods
Assessing genetic diversity of Hamdani sheep breed in Kurdistan region of Iraq using microsatellite markers
No full textThe genetic variation in Hamdani sheep in the Kurdistan region of Iraq was studied using 35 microsatellite markers. All 35 markers were found to be highly polymorphic. The mean number of observed alleles ranged from four at BMS1494 to twenty five at BM6444 and INRABERN185 loci. The polymorphic information content (PIC) values ranged from 0.208 for BMS1494 loci to 0.935 for INRABERN185 with an average value of 0.744. The overall observed and expected heterozygosity values were 0.407 and 0.764, respectively. Test of genotype frequencies for deviation from the Hardy-Weinberg equilibrium (HWE) at each locus, revealed a significant departure from HWE due to loss in heterozygotes by high level of inbreeding. The average inbreeding value for the 35 markers investigated was 0.469. The high observed heterozygosity is an indication of genetic variability that could be used for developing efficient utilization and genetic improvement strategies for Hamdani sheep
How strongly do hydrogen and water molecules stick to carbon nanomaterials?
No full textThe interaction strength of molecular hydrogen and water to carbon nanomaterials is relevant to, among many applications, hydrogen storage, water treatment, and water flow. However, accurate interaction energies for hydrogen and water with carbon nanotubes (CNTs) remain scarce despite the importance of having reliable benchmark data to inform experiments and to validate computational models. Here, benchmark fixed-node diffusion Monte Carlo (DMC) interaction energies are provided for hydrogen and water monomers inside and outside a typical zigzag CNT. The DMC interaction energies provide valuable insight into molecular interactions with CNTs in general and are also expected to be particularly relevant to gas uptake studies on CNTs. In addition, a selection of density functional theory (DFT) exchange-correlation (xc) functionals and force field potentials that ought to be suitable for these systems is compared. An unexpected variation is found in the performance of DFT van der Waals (vdW) models in particular. An analysis of the peculiar discrepancy between different vdW models indicates that medium-range correlation (at circa 3 to 5 Å) plays a key role inside CNTs and is poorly predicted by some vdW models. Using accurate reference information, this work reveals which xc functionals and force fields perform well for molecules interacting with CNTs. The findings will be valuable to future work on these and related systems that involve molecules interacting with low-dimensional systems

Mechanisms of adsorbing hydrogen gas on metal decorated graphene
No full textHydrogen is a key player in global strategies to reduce greenhouse gas emissions. In order to make hydrogen
a widely used fuel, we require more efficient methods of storing it than the current standard of pressurized
cylinders. An alternative method is to adsorb H2 in a material and avoid the use of high pressures. Among many
potential materials, layered materials such as graphene present a practical advantage as they are lightweight.
However, graphene and other 2D materials typically bind H2 too weakly to store it at the typical operating
conditions of a hydrogen fuel cell, meaning that high pressure would still be required. Modifying the material,
for example by decorating graphene with adatoms, can strengthen the adsorption energy of H2 molecules, but
the underlying mechanisms are still not well understood. In this work, we systematically screen alkali and
alkaline-earth metal decorated graphene sheets for the static thermodynamic adsorption of hydrogen gas from
first principles and focus on the mechanisms of binding. We show that there are three mechanisms of adsorption
on metal decorated graphene and each leads to distinctly different hydrogen adsorption structures. The three
mechanisms can be described as weak van der Waals physisorption, metal adatom facilitated polarization, and
Kubas adsorption. Among these mechanisms, we find that Kubas adsorption is easily perturbed by an external
electric field, providing a way to tune H2 adsorption. This work is foundational and builds our understanding of
H2 adsorption under idealized conditions
Analysis of the Application current X2 Interface Handover Process in LTE Technology
No full textLTE (Long Term Evolution) is a 4G technology which is in the developmental period. In its development we need to know the integrity of LTE networks in providing reliable service of the mobility when service users, so we need to discuss the handover process that occurs in LTE, where this handover process will determine the ability of communication networks in maintining the communication link is going. Problems arise when we talk handover is how the data transfer process occurs in LTE. X2 is an interface that must be passed whentheprocess of transferring data of time of handover between two eNodeB adjacentpieces in LTE. The capabilities of interface X2 also makes effect to maximization of the function on handover process, so it is necessary to analyze the function of interface X2 when handover happen between eNodeB in LTE. This research can be seen that the LTE quaranteering handover process when through on X2 interface at high speed that is greater than 60 km/hour. The existence makes use of the time required to performs faster handovers, seen from simulation result with TTT = 0,034 ms , Hom = 2,029 dB and TTD = 0,165 ms at speed 200 km/hour and angle direction of movement of user is 00 dan 600 . In addition , the faster movement of the user, the smaller the time required to perform handovers because the user through the area or areas slices cell or cell handover
