This document summarizes a study on the effect of longitudinal weld pool oscillation (LWPO) on the tensile properties of mild steel welds. Mild steel plates were welded with varying frequencies (0-400 Hz) and amplitudes (0-30μm) of LWPO. Test specimens were tested and properties like yield strength, ultimate tensile strength, elongation and impact strength were determined. The results showed that properties like yield strength and ultimate tensile strength improved significantly with LWPO compared to stationary welds. The maximum 21.37% increase in yield strength and 20.87% increase in ultimate tensile strength occurred at 400Hz and 5μm oscillation. Microstructural analysis found that

This document discusses accelerating molecular docking simulations using graphics processing units (GPUs). It finds that GPUs can provide a 6.9x speedup over CPUs for docking simulations. This reduces the time needed to screen a library of 1 million drug candidates from over 2 days using CPUs to less than 2 days using GPUs. GPUs also provide an energy reduction of 68% for the same work, reducing the energy needed from 0.034 kWh per simulation to 0.011 kWh. This could save over £3,000 in energy costs for a single experiment screening 1 million molecules.

This document proposes a hypothesis for a targeted drug delivery system to reduce scarring after glaucoma surgery. It suggests encapsulating the antifibrotic drug mitomycin C (MMC) in LDL receptor-targeting chitosan nanoparticles. These nanoparticles could be delivered via hyaluronic acid film to activated human Tenon's capsule fibroblasts at the surgical site, which overexpress the LDL receptor. This would allow the MMC to be taken up by the targeted cells via receptor-mediated endocytosis, reducing toxicity while increasing effectiveness in preventing excessive scarring. Testing is needed to confirm the low cytotoxicity of the chitosan-based drug carrier and its ability to gradually release the nanoparticles at the surgical site. If

Searching is one of the important operations in computer science. Retrieving information from
huge databases takes a lot of processing time to get the results. The user has to wait till the completion
of processing to find whether search is successful or not. In this research paper, it provides a detailed
study of Binary Search and how the time complexity of Binary Search can be reduced by using Odd
Even Based Binary Search Algorithm, which is an extension of classical binary search strategy. The
worst case time complexity of Binary Search can be reduced from O(log2N) to O(log2(N-M)) where
N is total number of items in the list and M is total number of even numbers if search KEY is ODD
or M is total number of odd numbers if search KEY is EVEN. Whenever the search KEY is given, first
the KEY is determined whether it is odd or even. If given KEY is odd, then only odd numbers from
the list are searched by completely ignoring list of even numbers. If given KEY is even, then only
even numbers from the list are searched by completely ignoring list of odd numbers. The output of
Odd Even Based algorithm is given as an input to Binary Search algorithm. Using Odd Even Based
Binary Search algorithm, the worst case performances in Binary Search algorithm are converted
into best case or average case performance. Therefore, it reduces total number of comparisons, time
complexity and usage of various computer resources.

2. Cavi
per radiofrequenza
e computer
Generalità
I cavi per radiofrequenza sono cavi coassiali singoli o composti e pertanto le loro caratteristiche tecniche sono
assimilabili a quelle descritte per i coassiali per TV digitale terrestre / satellitare.
Si differenziano però da questi ultimi per le loro applicazioni che sono più vaste. Inoltre questi cavi derivano
costruttivamente dalle normative americane MIL C-17, da cui la caratteristica sigla “RG”.
I cavi RG 75 Ω sono prevalentemente utilizzati negli impianti TV a circuito chiuso ed in quei sistemi che contengono
segnali video TV. In questa categoria abbiamo gli articoli RG 6 A/U, RG 11 A/U e RG 59 B/U.
I cavi 50 Ω sono utilizzati per:
• Trasmettitori radio AM – FM
• Trasmettitori TV
• Trasmettitori dati
• Strumenti di misura
• Sistemi d’antenna
A questa famiglia appartengono i cavi RG 58 C/U, RG 213 /U, RG 214 /U, RG 174 /U.
I cavi 93 Ω sono utilizzati per i sistemi di computer. In tale famiglia si inseriscono gli RG 62 A/U e RG 71 B/U.
I cavi per computer sono cavi a coppie che utilizzano i seguenti protocolli di comunicazione:
• EIA RS 232
• EIA ES 485
• EIA ES 422
I principali componenti di un cavo per computer sono:
• Conduttore
• Nastro poliestere
• Schermo
• Filo di drenaggio
• Guaina
Sono presenti conduttori flessibili di rame rosso di sezioni 0,22 mm2, 0,50 mm2 , e/o 0,81 mm2 . L’isolamento dei
conduttori interni è in PVC, in Polietilene o in Polpipropilene e la colorazione secondo la tabella allegata.
Lo schermo è costituito dal nastro Alluminio/Poliestere e dal filo di drenaggio in rame stagnato; quest’ultimo consente,
da un lato, di scaricare verso l’esterno le cariche elettrostatiche che si accumulano sul nastro e, dall’altro, di garantire la
continuità del potenziale dello schermo; in tal modo si genera una vera e propria gabbia di Faraday.
La guaina è di colore grigio; un colore alternativo può essere realizzato su richiesta.

3. Radio Frequency and Computer
Cables
General Information
The cables for radiofrequency are single or composed coaxial cables and therefore their technical features can be
assimilated to those of the coaxial cables used for Standard Digital/Satellite TV.
They are different from the latter because their uses are wider. Moreover these cables are originally manufactured
according to the American norms MIL C-17, which give them their characteristic abbreviation “RG”.
RG cables at 75 Ω are mainly used in closed circuit TV equipments and in general in those systems which uses TV video
signals. Items RG 6A/U, RG 11 A/U and RG 59 B/U belong to this category.
50 Ω cables are used for:
• AM-FM radio transmitters
• TV transmitters
• Data transmitters
• Measuring instruments
• Antenna systems
RG 58C/U, RG 213/U, RG 214/U and RG 174/U belong to this group.
93 Ω cables are used for computer systems and include RG 62A/U and RG71B/U.
Computer cables are paired cables which use the following communication protocols:
• EIA RS 232
• EIA RS 485
• EIA RS 422
The main components of a computer cable are:
• Conductors
• Polyester tape
• Screen
• Drainage wire
• Sheath
Flexible tin plated copper conductors with sections of 0,22 mm2, 0,35 mm2, and/or 0,81 mm2 are used. The insulation of
the inner conductors is in PVC or in Polyethylene or in Polypropylene and coloured according to the attached table. The
shield is made of Aluminium/Polyester and the drain wire is in tin plated copper; the latter enables the electrostatic
charges which accumulate on the tape to be discharged towards the exterior. It also ensures the continuity of the load
on the shield, in this way a real “Faraday cage” is generated.
The outer sheath is grey; an alternative colour can be produced on request.
