Thermal energy storage technology has evolved as one of the prominent methods storing thermal when it is available and utilized per requirements. In recent years, found a variety applications for management, such buildings, batteries, electronics, cold storage, textiles, solar systems. Phase Change Material (PCM) taken lead among all other materials because various merits high density, ease use, low cost, volume change, environmental friendliness, easy availability, chemical stability....

Abstract This paper investigates the different material removal mechanisms that occur during quasi-continuous wave fiber laser drilling using millisecond pulses on stainless steel 304 samples and studies their effect hole quality. A high-speed imaging camera is integrated with an in-situ setup to capture process. Based images, four were observed, which include vaporization, melt-expulsion at entrance, melt-ejection exit, explosive boiling. Vaporization occurs all fluences beyond a certain...

Abstract Alternaria blotch, caused by alternata f. sp. mali , poses a substantial economic threat to apples ( Malus domestica Borkh.) cultivation. Despite its significance, comprehensive understanding of the resistance responses recently introduced commercial apple cultivars remains underexplored in scientific literature. This study explored potential within germplasm collection, focusing on identifying with inherent pathogen. Evaluation gene pool for identified five cultivars, Skyline...

Extra-cytoplasmic function (ECF) σ-factors are widespread in bacteria, linking environmental stimuli with changes gene expression. These transcription factors span several phylogenetically distinct groups and remarkably diverse their activation regulatory mechanisms. Here, we describe the structural biochemical features of a Mycobacterium tuberculosis ECF factor σJ that suggests SnoaL_2 domain at C-terminus can modulate activity this initiation absence cognate anti-σ factor. M. bind promoter...

ArgO and LysE are members of the family exporter proteins ordinarily mediate export l-arginine (Arg) in Escherichia coli l-lysine (Lys) Arg Corynebacterium glutamicum, respectively. Under certain conditions, also mediates Lys export. To delineate arrangement cytoplasmic membrane E. coli, we have employed a combination cysteine accessibility situ, alkaline phosphatase fusion reporters, protein modeling to arrive at topological model ArgO. Our studies indicate that assumes an Nin-Cout...

High temperature requirement A (HtrA) are allosterically regulated enzymes wherein effector binding to the PDZ domain triggers proteolytic activity. Yet, it remains unclear if inter-residue network governing allostery is conserved across HtrA enzymes. Here, we investigated and identified interaction networks by molecular dynamics simulations on representative proteases,

Mycobacterium tuberculosis has multiple σ factors which enable the bacterium to reprogram its transcriptional machinery under diverse environmental conditions. σ(J), an extracytoplasmic function factor, is upregulated in late stationary phase cultures and during human macrophage infection. σ(J) governs cellular response hydrogen peroxide-mediated oxidative stress. differs from other canonical owing presence of a SnoaL_2 domain at C-terminus. crystals belonged tetragonal space group I422,...

Quasi-continuous wave (QCW) fiber lasers have revolutionized micro-hole drilling in various industries by generating highenergy pulses lasting milliseconds.A single pulse of this laser can drill micro-holes with aspect ratios exceeding 10 on metal sheets ranging from 1-5 mm thick.However, challenges like hole taper and burr formation limited their widespread adoption.Despite being introduced 2011, there is research QCW lasers.To overcome the challenges, understanding quality optimizing...

ABSTRACT An investigation of Alternaria blotch in apple orchards was conducted to evaluate the effectiveness fungicides, plant extracts and bioagents against mali through development integrated disease management strategies. Under pot conditions, potential combinations biocontrol agents for mitigating were evaluated. Furthermore, polyhouse studies showed that such as Trichoderma viride , Bacillus subtilis Pseudomonas fluorescens have control potential. Moreover, this research explored impact...

The crystal structure of Mycobacterium tuberculosis high-temperature requirement A (HtrA) protein was determined at 1.83 Å resolution. This membrane-associated protease is essential for the survival M. . reveals that interactions between PDZ domain and catalytic in HtrA lead to an inactive conformation. finding consistent with its proposed role as a regulatory conditionally activated upon appropriate environmental triggers. provides basis directed studies evaluate this pathways are...
