Opis:: Tomato (Solanum lycopersicum L.) is attacked by Pseudomonas syringae pv. tomato causing heavy damage to the crops. The present study focused on the application of aqueous fruit extracts of neem (Azadirachta indica L.) on a single node of aseptically raised tomato plants. Observations were done, and the changes in the activity and isoenzyme profile of polyphenol oxidase (PPO) and lysozyme, both at the site of treatment as well as away from it, were noted. The results demonstrate that neem extract could significantly induce the activities of both the enzymes as well as upregulate the de novo expression of additional PPO isoenzymes. Induction of systemic acquired resistance (SAR) by natural plant extracts is a potent eco-friendly crop protection method.

Opis:: Biocontrol of plant diseases has emerged as an eco-friendly measure of plant protection and has experienced a lot of devotion in the last two decades. Biocontrol agents include application of microbial agents, their secretion products and natural extracts from different parts of several plants. The present study, therefore, aimed at evaluating the potency of aqueous extracts of Tagetes erecta L. (marigold) in controlling bacterial speck disease in tomato plants. The experimental design consisted of two groups of 50 plants each: group 1 – sprayed with sterile water (control); and group 2 – sprayed with marigold extract. Spraying was performed under aseptic conditions at the third node from the base of each plant. Challenge inoculation with the bacterial speck pathogen Pseudomonas syringae pv. tomato was performed to analyze the disease severity on the test plants. The parameters of study were analysis of alteration in the activity and gene expression of peroxidase (POX), phenyl ammonia lyase (PAL), and polyphenol oxidase (PPO), as well as isoform expression of POX and PPO. The results demonstrated strong inductive effects of the extract on the activity and genes of POX, PAL and PPO. De novo expression of POX and PPO isoforms following marigold extract treatment was also observed. The observations indicate that marigold extract could be a promising biopesticide.

Opis:: Phylloplane microbes have been studied as strategic tools in management against plant pathogens. Non-pathogenic bacteria and fungi have been applied as crop protectants against various plant diseases. The present study aimed at evaluating the potentiality of Aspergillus niger spores in altering the activity of four key enzymes related to defense in tomato. The experiment was designed such that two groups of 50 tomato plants were considered: group 1 – sprayed with autoclaved distilled water (control) and group 2 – sprayed with A. niger spores. Spraying was carried out under aseptic conditions. The experimental parameters included analysis of the activity of peroxidase (POX), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL) and tyrosine ammonia lyase (TAL) as well as expression of POX and PPO isoforms. The results demonstrated an inductive effect of A. niger on the activity of POX, PPO, PAL and TAL. Enhanced expression of POX and PPO isoforms was also observed. The results indicated that A. niger can be considered probiotic for the management of tomato against its phytopathogens.

Opis:: In recent times, the concept of hard turning has gained awareness in metal cutting as it can apparently replace the traditional process cycle of turning, heat treating, and finish grinding for assembly of hard, wear-resistant steel parts. The major apprehension in hard turning is the tool vibration, which affects the surface finish of the work piece, has to be controlled and monitored. In order to control tool vibration in metal cutting, a magnetorheological fluid damper which has received great attention in suppressing tool vibration was developed and used. Also an attempt has been made in this study to monitor tool vibration using the skewness and kurtosis parameters of acoustic emission (AE) signal for the tool holder with and without magnetorheological damper. Cutting experiments were conducted to arrive at a set of operating parameters that can offer better damping characteristics to minimize tool vibration during turning of AISI4340 steel of 46 HRC using hard metal insert with sculptured rake face. From the results, it was observed that the presence of magnetorheological damper during hard turning reduces tool vibration and there exist a strong relationship between tool vibration and acoustic emission (AERMS) signals to monitor tool condition. This work provides momentous understanding on the usage of magnetorheological damper and AE sensor to control and monitor the tool condition during turning of hardened AISI4340 steel.
W ostatnich latach, w obróbce skrawaniem wzrasta zainteresowanie koncepcją toczenia na twardo, ponieważ może ono zastąpić tradycyjny proces toczenia, utwardzania i szlifowania stosowany przy wykonywaniu twardych, odpornych na zużycie cześci metalowych. Głównym problemem przy twardym toczeniu są wibracje narzędzia, które muszą być monitorowane i kontrolowane, gdyż wpływają na wykończenie powierzchni elementu obrabianego. W celu kontrolowania wibracji narzędzia przy obróbce skrawaniem autorzy zastosowali tłumik z płynem o właściwościach reologicznych sterowanych polem magnetycznym. Podjęto także próbę monitorowania wibracji na podstawie parametrów skośności i kurtozy sygnałów akustycznych (AE) emitowanych przez uchwyt narzędzia, mierzonych w warunkach bez tłumika i z tłumikiem magnetoreologicznym. Przeprowadzono szereg eksperymentów z toczeniem stali AISI4340 o twardości 46 HRC przy użyciu narzędzia z płytką z twardej stali, o geometrycznie kształtowanym ostrzu, firmy Taegu Tec. Otrzymano zbiór parametrów roboczych, wyznaczając na ich podstawie lepsze charakterystyki tłumienia i osiagając minimalizację wibracji narzędzia. Wyniki eksperymentów wskazują, że obecność tłumika magnetoreologicznego redukuje wibracje i że istnieje silna zależność miedzy wibracjami narzędzia i wartością skuteczną sygnału emisji akustycznych (AERMS). Praca przyczynia się do znacznie lepszego zrozumienia funkcji tłumika magnetoreologicznego i czujnika emisji akustycznych przy monitorowaniu stanu narzędzia przy toczeniu utwardzonej stali AISI4340.

Opis:: This work describes a 4-bit Flash ADC with low power consumption. The performance metrics of a Flash ADC depend on the kind of comparator and encoder used. Hence openloop comparator and mux-based encoder are used to obtain improved performance. Simulation results show that the simulated design consumes 0.265mW of power in 90nm CMOS technology using cadence-virtuoso software. The circuit operates with an operating frequency of 100MHz and a supply voltage of 1V.

Opis:: Barley phylloplane is seriously colonized by Drechslera graminea, the causal agent of leaf stripe disease in the hos. The present study involved the elucidation of alterations induced in the protein content of the host due to Drechslera infection. Naturally growing barley plants were obtained from fields and Drechslera graminea was isolated and identified from diseased plants’ leaves. After identification and preparation of the pure culture, the pathogen was inoculated on plants grown under aseptic and controlled laboratory conditions. Changes in the total soluble cytoplasmic proteins and defense enzymes of the host such as polyphenol oxidase (PPO), peroxidase (POX), phenylalanine lyase (PAL) and tyrosine ammonia lyase (TAL) were observed up to 5 h after inoculation. The results demonstrated a significant effect of the pathogen on the cytoplasmic protein expression of the host as well as in its defense system.

Opis:: Elevated water tanks in an empty condition, though not important in structural design, becomes an important problem in seismic design. The objective of the present research is to investigate the elevated water tanks in empty and in filled conditions and to emphasize the importance of seismic response. Four elevated tanks with various parameters are selected for seismic analysis with the base isolation technique. It is found out that empty tanks are highly vulnerable to earthquake effects, whereas filled tanks can be mitigated by providing base isolation. A simple experimental investigation has also been carried out to validate the analytical results.

Opis:: The high harmonics produced by focusing an intense femtosecond laser in a gas are theoretically shown to be locked in phase. The physics of this locking is discussed and a new method based on quantum interference in two-photon, two-color ionization allowing to retrieve the relative phase of harmonic pairs is described. The main result is that the 5 harmonics of orders 11-19 produced in argon generate a train of subfemtosecond pulses with a period of 1.35 fs and a duration of 250 attoseconds.

Opis:: An early, rapid and definite detection for the presence of biowarfare agents, pathogens, viruses and toxins is required due to their harmful effect to human population. Those potentially encountering the aforementioned include people involved in civil rescue and security, homeland security, military operations, as well as public transportation securities such as airports, metro and railway stations. This work informs the reader of an electrochemical genosensor with an integrated microsystem array combined with microtube fluidics that allows simultaneous detection of different biowarfare agents such as Bacillus anthracis, Brucella melitensis, Bacteriophage lambda, Francisella tularensis, Burkholderia mallei, Coxiella burnetii, Yersinia pestis, and Bacillus thuringiensis var. kurstaki. The chip electrode arrays were modified via coimmobilisation of a 1:100 (mol/mol) mixture of a thiolated probe and a polyethyleneglycol terminated bipodal thiol. Herein, PCR products from relevant biowarfare agents were detected reproducibly through a sandwich assay format with the target hybridised between a surface immobilised probe into the electrode and a horseradish peroxidase-labelled secondary reporter probe, which provided an enzyme based electrochemical signal. Cross-reactivity studies over potential interfering DNA sequences have demonstrated high selectivity using the developed platform producing high-throughput.
