Understanding the role and significance of the different components of the trunk neuro-musculo-skeletal system is of great importance for development of proper preventive and curative measures for low back pain. The experimental investigations, using LUMBAR moment measurement devices, are considered the most useful sources of information for detail understanding of the biomechanics of trunk and its components. This paper describes the conceptual design of a new LUMBAR moment measurement system, based on minimum deflection, anthropometric characteristics, and measurement considerations. The system is capable to measure the 3-D trunk MOMENTS using uni-directional torque sensors within a proper configuration of links and joints. Some other features of the system include convergence of its joints, high stability, and ability to adapt to a wide range of anatomical postures is standing and sitting positions.

Gravitational multipole MOMENTS of the Sun are still poorly known. Theoretically, the difficulty is mainly due to the differential rotation for which the velocity rate varies both on the surface and with the depth. From an observational point of view, the multipole MOMENTS cannot be directly measured. However, recent progresses have been made proving the existence of a strong radial differential rotation in a thin layer near the solar surface (the leptocline). Applying the theory of rotating stars, we will first compute values of J2 and J4 taking into account the radial gradient of rotation, then we will compare these values with the existing ones, giving a more complete review. We will explain some astrophysical outcomes, mainly on the relativistic Post Newtonian parameters. Finally we will conclude by indicating how space experiments (balloon SDS flights, Golf NG, Beppi-Colombo, Gaia...) will be essential to unambiguously determine these parameters.

The mean and variance of the Lagrangian Katz family of distribution (LKD), the basic Lagrangian Katz distribution of Type I (LKD-I) and Type II (LKD-II) are provided in an easy method. The recurrence relation between the non-central, central and factorial MOMENTS, and the recurrence relation between MOMENTS and cumulants of LKD, LKD-I and LKD-II are given. The first four cumulants of LKD-I and LKD-II are provided.

To design a mosque is doubtlessly one of the simple, yet intricate problems in architecture. Simple, as the mosque does not have a complex spatial composition; intricate, because its perceived logical beauty necessitates a deep understanding of diverse fields of knowledge. The article enters the field of environmental psychology in quest of designing an appropriate environment for the basic prerequisite of prayer, i.e. contemplation, although the article intentionally concentrates on a single semiotic dimension of the mosque, but it is hoped that the findings will be useful for partial understanding of the logical aesthetic system in the "House of Lord".
