Hola!
Pense mucho en compartir esto ya que las imagenes son muy fuertes y me preocupaba un poco el que diran o molestar a alguien con ello, pero despues de un rato decidí hacerlo pq muchas veces estamos cegados a la muy triste realidad que se esta viviendo en este mundo, y algunos diran "que ganamos traumatizandonos con estas imagenes si no podemos hacer nada para detener esto!" se los digo pq lo llegue a pensar, pero entonces recorde un testimonio de una persona que estuvo en presencia de Dios y El Señor le pasaba una escena de su vida en la que vio alguna noticia de este tipo en la tv y se sintió triste y angustiado, pero no hizo nada, y Dios le dijo "Hijo, esa tristeza que te estrujaba el corazon al ver esta noticia era Yo que te gritaba que tu podias hacer algo al respecto!!, la oración, el sacrificio, el ayuno, las ofrendas, la caridad!!! son tantas cosas que pueden ayudar en esta situacion!" ... Recordando esto pense que no podia dejarlo pasar y me atreví a subir esta presentacion hecha por mi marido ya que tal vez mas de uno nos podamos sensibilizar y decidamos hacer algo, no se trata de hechar culpas, hacer polemica, ni estar de ningun bando segun historia ni religion, sino de lo que mencione al principio pq creo que juntos podriamos hacer alguna diferencia, esta en uds compartirlo. A pesar que estas imagenes abundan en la red, les pido disculpas si a alguien ofendi con esto. Y si por el contrario se logra subir una oracion mas al cielo, me sentire mas que satisfecha, Gracias.

COMPUTATIONAL STUDY OF COOLING OF PV SOLAR PANEL USING FINNED HEAT PIPE TECHN...IAEME Publication
Various solar energy technologies exist and they have different application techniques in the generation of electrical power. The widespread use of photovoltaic (PV) modules in such
technologies has been relatively high costs and low efficiencies. The efficiency of PV panel decreases as the operating temperature increases. This is due to reflection from the top surface, absorption of heat by the parts other than the cell, absorption of heat from the other portion of the spectrum.
Thermo Structural Analysis on Cylinder Head of 4 Stroke VCR Diesel EngineDr. Amarjeet Singh
The main aim of the project is to analyse the design performance of VCR 4 stroke Diesel engine cylinder head at the compression ratio 16.5 using Ansys software. The basic modelling is done on CATIA V5 software. The design exposition can be done structurally and thermally in ansys. By the structural analysis the maximum and minimum von misses stress, total deformation can be determined, the maximum gas pressure required for this analysis is taken from the experimental set up of VCR engine. With the steady state thermal analysis we will get the maximum temperature distribution and total heat flux of the cylinder head with the initial pressure value. The results of both the expositions are used to decide the critical areas of the cylinder head which require further amendment and also the quality of design. If the maximum stress is less than the material strength of the cylinder head then the basic design criteria can be achieved.
Experimentation on heat pipe and cfd analysis for performance enhancementeSAT Journals
Abstract
Heat Pipe is a heat transfer device used in many applications and it is very similar in some respects to the thermosyphon. Since there were several limitations of thermosyphon, heat pipe was developed. The idea of the heat pipe was first suggested in 1942, since then over a several decades the serious development of a heat pipe took place. Heat pipe mainly consists of three regions viz. evaporator, adiabatic and condenser section. The heat pipe differs from the thermosyphon by virtue of its ability to transport heat against gravity by an evaporation-condensation cycle. This research work includes experimentation on available heat pipe, development of CFD model and its validation with experimental results using CFD Tool. The results obtained by CFD are in good agreement with an experimental results. Since the heat pipe is used for transferring the heat, this research work focuses on increasing the heat transfer by modified model, modifications in terms of increased surface area, is proposed. From CFD analysis it was found that the proposed modified heat pipe shows enhancement in performance in terms of heat transfer rate by 19% when it is simulated for without heat sink case and 45% while with heat sink case, compared to conventional heat pipe. The mixture multiphase model from CFD too is used for simulation of heat pipe.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Screw Extruder for Pellet Injection System
Sharadkumar K. Chhantbar
PG student, A. D. Patel Institute of Technology, New V. V. nagar, Anand, Gujarat, India
Abstract— Solid hydrogenic pellets are used as fuel for fusion energy reactor. A technique for continuous
production of solid hydrogen and its isotopes by a screw extruder is suggested for the production of an unlimited
number of pellets. The idea was developed and patented by PELIN laboratories, Inc. (Canada). A Gifford
McMahon cryocooler is used for the generation of solid hydrogenic fluid pellets. Requirements of the pellets is
depends upon the energy to be produced by tokamak. This review paper focuses on the model for the screw
extruder for solidification of hydrogen ice having high injection reliability.
Keywords: screw extruder, cryocooler
I. INTRODUCTION
Future fusion reactors should be equipped
with a fuelling system operating in a steady state
mode. There are three techniques for plasma fuelling:
by gas puffing, by compact toroids and by injection
of pellets produced from solidified hydrogen
isotopes. A key task of the injection is to develop a
reliable pellet injector capable of injecting, in the
steady state mode, an unlimited number of pellets
into the plasma core. Several techniques for
continuous pellet production have been proposed.
One is a screw extruder type pellet injection system.
Another technique is to produce pellets by a porous
pellet generator. Recently the screw extruder type
pellet injection system has been designed and tested.
II. DEVELOPMENT OF EXTRUDER
TYPE PELLET INJECTOR
R. Viniar et. al., Developed a screw
extruder to produce a deuterium ice in 2000. A
cylindrical rod of 2 mm in diameter and 100 m in
length was extruded over 3000s. The deuterium
solidifies by a liquid helium heat exchanger. A
schematic diagram of the pellet injector is shown in
Figure1. It consists of vacuum chamber (1) with an
extruder (2), which equipped with helium heat
exchanger (3) and screw (4), A rotating driver (5)
connected to screw, A propellant gas valve (6),
chopper (7), a gun barrel (8), and diagnostic chamber
(9). A transparent chamber (10) is attached to the
extruder exit and equipped with pumping system
(11).

R. Sakamoto et. al., in his paper
“Development of advance pellet injector systems for
plasma fueling” in 2008, the cooling is done by cryo-
cooler instead of liquid helium. Its key design futures
are as follows,
Cooling by compact cryo-coolers: the pellet
injector is operated using electrical input only,
which is the most fundamental facility in a
laboratory, instead of a complicated liquid

helium supply system. This design enables
flexible and reliable operation.
Screw extruder for solid hydrogen production:
The screw extruder can produce solid hydrogen
rod via simultaneous replenishment, liquefaction,
and solidification of hydrogen gas. This design
steady state operation in principle.
Pneumatic pipe-gun acceleration: the design
enables reliable and reproducible pellet injection
with easy injection-timing control.
The screw extrusion concept, which was
proposed by Mitsubishi Heavy industry and
developed by PELIN L laboratory, can produce a
solid hydrogen rod continuously. A conceptual
drawing of the screw extruder is shown in Fig.1.
There are two Gifford-McMahon cycle 4 K cryo-
coolers to cool the cryo-cylinder, the total cooling
capacity of the cryo-coolers is 20 W at 8 K. The
lower part of a copper cryo-cylinder is cooled to
below 6 K in the standby phase.
Figure 2 Conceptual drawing of screw extruder
[R. Sakamoto et. al, 2008]
Hydrogen gas is pre cooled in a heat
exchanger at the same temperature with the thermal
shield, and then flows onto the cooper cryo-cylinder
to be liquefied and solidified, while the solid
hydrogen rod is extruded by the rotating screw from a
nozzle (Fig.2).

J.W. Leachman et. al., in his paper “Model
of a Twin-Screw Extruder operating with a
Cryocooler for the Solidification of Deuterium” in
2009, Analysis carried out using the numerical
model. Nine parameters are considered in his
sensitivity analysis.
Figure 4 Sensitivity of extruder performance
[J.W. Leachman et. al, 2009]
Figure 4 indicates that the extruder
performance is most sensitive to two-phase
convection coefficient, Followed in order by latent
heat of fusion, Liquid convection coefficient, and
liquid heat capacity.
III. CONCLUSION
The sensitivity of extruder
performance is complex to control due to two phase
flow. Among two methods of producing solid
hydrogen and its isotopes, the GM cryocooler based
cooling system is preferable to control load capacity
over liquid helium heat exchanger system.
