There are Two Different Language Systems in the Brain  [PDF]
Alfredo Ardila
Journal of Behavioral and Brain Science (JBBS) , 2011, DOI: 10.4236/jbbs.2011.12005
Abstract: In this paper it is emphasized that human language has two rather different dimensions corresponding to two different language systems: lexical/semantic and grammatical. These two language systems are supported by different brain structures (temporal and frontal), and based in different learning strategies (declarative and procedural). In cases of brain pathology, each one can be independently impaired (Wernicke aphasia and Broca aphasia). While the lexical/semantic language system may have appeared during human evolution long before the contemporary man, the grammatical language system probably represents a relatively recent acquisition. Language grammar may be the departing ability for the development of the metacognitive executive functions and is probably based in the ability to internally represent actions.
The Light as Composed of Longitudinal-Extended Elastic Particles Obeying to the Laws of Newtonian Mechanics  [PDF]
Alfredo Bacchieri
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.59092
Abstract:

It is shown that the speed of longitudinal-extended elastic particles, emitted during an emission time T by a source S at speed u (escape speed toward the infinity due to all the masses in space), is invariant for any Observer, under the Newtonian mechanics laws. It is also shown that a cosmological reason implies the light as composed of such particles moving at speed u (function of the total gravitational potential). Compliance of c with Newtonian mechanics is shown for Doppler effect, Harvard tower experiment, gravitational red shift and time dilation, highlighting, for each of these subjects, the differences versus the relativity.

A Feasible Experiment Contrary to the 2nd Postulate of SR  [PDF]
Alfredo Bacchieri
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.69139
Abstract: Assuming the light as composed of longitudinal-extended elastic (and massive) particles emitted during an emission time T at speed c (=u) (with u the escape speed from all the masses, toward the infinity), it is shown that c is invariant (under the Newtonian mechanics laws), for an Observer fixed to the initial emission point Ep (the point where the emission starts), in spite of any motion of the source (of light) with respect to Ep. On the contrary, an Observer, in motion from Ep during the emission, will state (indirectly) a Galilean variation of c which can be proved and evaluated by an appropriate feasible experiment described here.
Evidences for a Unified Physics, in Full Accordance with the Newtonian Laws  [PDF]
Alfredo Bacchieri
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.715193
Abstract: We show that the speed of a longitudinal-extended, elastic (variable length), and massive particle, emitted by a source during an emission time T, at speed u (escape speed from all the masses in space), is invariant for every real measurement, (intending a measurement requiring an interaction light-matter), in spite of any reciprocal motion source-Observer. Thus we may argue that the light has to be composed of such particles (photons) moving at speed c = u. Compliance of these photons with Newtonian mechanics is shown for many effects, (like the Doppler effect, redshift, time dilation, etc.), highlighting the differences versus the Relativity. In the 2nd part, on the assumption that the electron charge can be considered as a point-particle fixed to the electron surface, always facing the atom nucleus during the electron revolution, we revised the light-matter interaction, showing that it only depends on the particular impacts between these photons and the circling electrons: for instance, on H atom, we found 137 circular orbits only, the last one being the ionization orbit, where the electron orbital speed becomes vi= c/1372. [Classical mechanics implies that orbiting electrons produce an electro-magnetic radiation causing their fall into the nucleus: on Section 3.5, the reason why the electron circular orbits are stable].
Three Conditions Leading to a Unified (Quasi-Newtonian) Physics  [PDF]
Alfredo Bacchieri
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.911129
Abstract: It is shown that the total escape speed u (i.e. from all the masses in space), which depends on the total gravitational potential U through the relation u = (2U)1/2, tends to c; then, under the 1st condition c = u, and assuming (as a 2nd condition) the light as composed of longitudinally-extended, elastic (i.e. variable length) and massive particles, (photons), emitted at speed u referred to the initial location (O) of their source, we show that c referred to O becomes invariant despite any motion of its source from O. We revised the Doppler effect for the light, the gravitational redshift cause, the time dilation, highlighting the differences with respect to the Relativity. In the 2nd part, considering (3rd condition) the electron charge as a point-particle fixed to the electron surface and facing the atom nucleus during the electron orbit, the light-matter interaction becomes a consequence of the particular impacts between these photons and the circling electrons: e.g., on H atom, we found 137 circular orbits only, the last one being the ionization orbit, where the electron orbital speed becomes v i= c/1372. [Classical physics, under the assumption that a circling electron should produce (like a macroscopic electric circuit), an electro-magnetic radiation, implies that this claimed effect has to cause the electron fall into its nucleus: on Section 2.5, we show that the e.m. radiation of a circling electron only happens between two circular orbits].
Effect of Breed and Sex on Pork Meat Sensory Evaluation  [PDF]
Sandra Rodrigues, Alfredo Teixeira
Food and Nutrition Sciences (FNS) , 2014, DOI: 10.4236/fns.2014.57070
Abstract:

This work had an objective to evaluate the sensory quality of two categories of pork meat from a commercial pork meat and a selected meat from the Portuguese black pork (Preto Alentejano breed). Sixteen animals were used, 8 females and 8 males from each breed. Animals had 80 - 100 kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar vertebra was used in the analysis. Sensory analysis was performed by a trained taste panel of 10 elements, in 5 sessions. All evaluation conditions were standardized, and the attributes studied were odor intensity, toughness, juiciness and flavor intensity. The taste panel found differences mainly between breeds. The panellists scored Preto Alentejano meat as being juicier, tenderer, and with richer taste than Commercial meat. The higher juiciness score of Preto Alentejano meat was probably attributable to the higher intramuscular fat content compared with Commercial meat. The Commercial pork was characterized mainly by high toughness.

Simple Adaptive Delta Operator Aircraft Flight Control for Accommodation of Loss of Control Effectiveness  [PDF]
Alfredo Cano, Kenneth Sobel
Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.84016
Abstract: A new proof for stability of delta operator simple adaptive control is presented in terms of a set of Linear Matrix Inequalities (LMIs). The paper shows how to design a feedforward gain to satisfy the LMIs over a polytope of loss of control effectiveness failures. The MATLAB Robust Control Toolbox is used to find the feedforward gain with the smallest norm that satisfies the LMIs. Examples are presented of the F/A-18 aircraft and the Innovative Control Effectors (ICE) tailless aircraft that show the design of a feedforward gain for a loss of control effectiveness in any one control effector. The designs use a fixed eigenstructure assignment controller for an inner loop augmented with the simple adaptive controller. Simulations of both aircraft include simultaneous loss of control effectiveness failure and lateral wind gust. Simulation results for the F/A-18 aircraft show that the adaptive controller achieves almost perfect tracking whereas the nonadaptive controller cannot achieve a coordinated turn when an aileron failure occurs. The ICE tailless aircraft uses sideslip, washed-out stability axis yaw rate, and stability axis roll rate feedback for both the inner loop eigenstructure assignment controller and the simple adaptive controller. However, the adaptive controller also uses bank angle feedback. Simulation results for the ICE tailless aircraft show that the adaptive controller achieves almost perfect tracking whereas the nonadaptive controller diverges when an all moving tip failure occurs.

Phenomenal Consciousness and the Sensorimotor Approach. A Critical Account  [PDF]
Alessandro Dell’Anna, Alfredo Paternoster
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.34064
Abstract: The paper discusses some recent suggestions offered by the so-called sensorimotor (or enactivist) theorists as to the problem of the explanatory gap, that is, the alleged impossibility of accounting for phenomenal consciousness in any scientific theory. We argue in the paper that, although some enactivist theorists’ suggestions appear fresh and eye-opening, the claim that the explanatory gap is (dis)solved is much overstated.
Climate Action Plan for the City of La Paz, BCS, Mexico: A Tool for Public Policy in a Coastal City  [PDF]
Antonina Ivanova, Alfredo Bermudez- Contreras
Current Urban Studies (CUS) , 2014, DOI: 10.4236/cus.2014.23024
Abstract: As a result of its coastal location and severe water scarcity condition, the city of La Paz, Baja Cali-fornia Sur, Mexico, is extremely vulnerable to the impacts of climate change. This work presents the main findings of the Climate Change Action Plan for the City of La Paz and Neighbouring Areas (PACCLAP) including its development process and the main results of its two larger components: first, the vulnerability to climate change in the area and the adaptation measures suggested; and second, the local greenhouse gas emissions inventory and the recommended mitigation measures. In addition, the proposed actions have important impacts directly related with the Municipality Development Plan, thus making the PACCLAP a valuable instrument to support current and future decision makers in the formulation of public policies to foster a more sustainable development and improve the wellbeing of the local society.
