Opis:
The paper presents a comparative analysis of the two resonant based converter topologies. The converter topologies selected are LLC resonant converter and the Quasi resonant converter. The modeling, analysis and control of both the converter is done and presented here for the case of the photovoltaic (PV) emulator. A PV emulator is basically a DC-DC converter having same electrical characteristics that of solar PV panel. The emulator helps to achieve real characteristics of PV system in a better way in an environment where using actual PV systems can produce inconsistent results due to variation in weather conditions. The complete system is modelled in MATLAB® Simulink SimPowerSystem software package. The Simulation results obtained from the MATLAB® Simulink SimPowerSystem software package for both topologies under steady and dynamic conditions are analyzed and presented. An evaluation table is also presented at the end of the paper, presenting the effectiveness of each topology.

Opis:
The study’s aim was to develop a novel sorbent for removing the color Congo red (CR) from water by precipitating (Mg/Al)-layered double hydroxide (LDH) at the nanoscale onto the waterworks sludge surface as a byproduct. To achieve an effective sorbent with the removal of over 91.19%, The utilization of nanoparticles, the addition of 1 g of sludge to 50 mL of water, and a molar ratio of 2 (Mg/Al) were the optimal production conditions for sorbent. In batch experiments, the optimal operating parameters were found to be 0.5 g of adsorbent in 50 mL of CR, pH of CR solution equal to 3, and a contact time of 3 hours at 200 rpm with 25 mg/L dyes. According to the study, the adsorption capacity was 23.576 mg/g. Additionally, the pseudo-second-order and Langmuir models provided accurate descriptions of the sorption data.

Opis:
This paper presents the complete analysis of Linear Induction Motor (LIM) under VVVF. The complete variation of LIM air gap flux under ‘blocked Linor’ condition and starting force is analyzed and presented when LIM is given VVVF supply. The analysis of this data is important in further understanding of the equivalent circuit parameters of LIM and to study the magnetic circuit of LIM. The variation of these parameters is important to know the LIM response at different frequencies. The simulation and application of different control strategies such as vector control thus becomes quite easy to apply and understand motor’s response under such strategy of control.

Opis:
Seeds of local trees, such Azadirachta indica A. Juss, Adenanthera pavonina L., Leucaena leucocephala (Lam.) de Wit and Eucalyptus spp., were used as aqueous extract at 25, 50 and 100 % concentration to control the activity of Meloidogyne javanica (Treub) Citwood. All seed extracts showed lethal effect on M. javanica eggs, and a gradual decrease in egg hatching and an increase in mortality of second-stage juveniles were observed with the increase in extract concentration. L. leucocephala was found to be most effective in reducing egg hatching, whereas 100 % mortality of juveniles was observed in the case of A. indica seed extract. Number of knots was significantly reduced at 100 % concentration when seeds of chick pea and mung bean were treated and soil was drenched with A. pavonina and Eucalyptus spp. seed extract.

Opis:
Leaves, stem and pneumatophore of Avicennia marina and leaves and stem of Rhizophora mucronata were used as the organic amendments at 0.1, 1 and 5% concentrations in the control of root rot fungi like (Fusarium spp., Rhizoctonia solani and Macrophomina phasoelina) and root knot nematode Meloidogyne javanica on potato. In pot experiments, germination of seeds, shoot length, shoot weight, root length, root weight and number of knots were signifi cantly increased when plant parts like leaves, stem and pneumatophore of A. marina and R. mucronata were used at 1 and 5% concentrations. There was a complete suppression in infection of R. solani and M. phaseolina when A. marina and R. mucronata were used at 5% concentration on potato. Maximum inhibition of knots of M. javanica was observed when powder made from mangrove plant parts was used at 1 and 5% concentrations. Powder from all plant parts, like leaves, stem and pneumatophore, was effective in suppression of root infecting fungi and root knot nematode.

W doświadczeniach wazonowych kiełkowanie nasion, masa pędu, długość korzenia, masa korzenia znacznie zwiększyły się, a liczba narośli zmniejszyła się, kiedy części roślin A. marina i R. mucronata, takie jak liście, łodygi i pneumatofory, stosowano w stężeniu 1 i 5%. Nastąpiło zupełne zablokowanie zakażenia przez R. solani i M. phaseolina, kiedy części roślin A. marina i R. mucronata stosowano w stężeniu 5% w uprawach ziemniaka. Maksymalne zahamowanie narośli wywoływanych przez M. javanica obserwowano, kiedy proszek zrobiony z części roślin namorzynowych stosowano w stężeniu 1 i 5%. Proszek ze wszystkich części roślin, takich jak liście, łodygi i pneumatofory, był skuteczny w blokowaniu działania grzybów porażających korzenie i nicieni Meloidogyne javanica.

Opis:
The present investigation was carried out to evaluate the potential of chitosan alone and in combination with various agricultural wastes for the management of rootknot nematode, Meloidogyne incognita on eggplant cv. ‘BR-112’ under greenhouse conditions. The results showed that chitosan as a single or joint treatment with agricultural wastes significantly (p ≤ 0.05) reduced root-knot indices, and the nematode population in soil. As a result, of this, the growth and growth yielding attributes of eggplant were remarkably augmented. Chitosan as an elicitor induced plant mediated systemic resistance against M. incognita in eggplant. The results of the study demonstrated that maximum reduction in eggmass/root, eggs/eggmasses, nematode population and root-knot indices, was acquired by the treatments: chitosan + onion and chitosan + mentha. It was followed by chitosan + Brassica, chitosan + urad and chitosan + coconut whereas, chitosan combined with corn cob waste was found to be the least effective when compared to the control. The application of chitosan alone was effective but not very satisfactory. Compared to the control applications of all the treatments significantly increased plant growth in terms of length, fresh and dry weights, pollen fertility, yield and biochemical parameters such as chlorophyll, carotenoid content and antioxidant enzymes. This may have been due to the eliciting activity of chitosan, causing systemic resistance in the plant and the release of various toxic chemical compounds during decomposition which have lethal effects against the second stage juveniles of M. incognita and nematode multiplication.

Opis:
Potato (Solanum tuberosum L.), an important food crop in the world, is susceptible to many fungal pathogens including Alternaria solani and Fusarium oxysporum causing Fusarium wilt and early blight diseases. Mycoparasitic fungi like Trichoderma encode chitinases, cell wall degrading enzymes, with high antifungal activity against a wide range of phytopathogenic fungi. In this study, a binary vector harboring endochitinase gene of ~1,000 bp was constructed and used to transform potato nodes through Agrobacterium-mediated transformation. Out of several primary transformants, two transgenic potato lines were verified for transgene insertion and integration by Southern blot. In a pot experiment for Fusarium resistance, the transgenic potato lines didn’t show any symptoms of disease, instead they remained healthy post infection. The transgenic potato lines exhibited 1.5 fold higher mRNA expression of endochitinase at 7 days as compared to 0 day post fungus inoculation. It was evident that the mRNA expression decreased over days of inoculation but was still higher than at 0 day and remained stable upto 30 days post inoculation. Similarly, for A. solani infection assay, the mRNA expression of the endochitinase gene was 3 fold higher 7 days post inoculation compared to expression at 0 day. Although the expression decreased by1.2 fold during subsequent days post infection, it remained stable for 30 days, suggesting that protection in transgenic potato plants against fungal pathogens was achieved through an increase in endochitinase transcript.

Opis:
Hyperhydricity is a frequently problem in plants during in vitro culture and affected micropropagation of plants. To develop an efficient in vitro regenerated system without hyperdydricity, we demonstrated the effect of different disinfected agents (mercuric chlorite and hypochlorite), growth regulators, their concentrations and combinations, Agar, pH, ammonium nitrate (NH₄NO₃) and number of subcultures. Mercuric chlorite at 0.07% and exposing time (9–10 min) was appropriate for hygienic culture. The shoots induced by Benzyladnine (BA) alone or in combination with α-Naphthaleneacetic acid (NAA) exhibited maximum multiplication with symptoms of hyperhydricity than those induced by Kinetin alone or in combination with NAA. Hyperhydricity was also reduced by increasing the concentration of agar, pH and elimination of NH₄NO₃ from the macroelements of Murashig and Skoog (MS) medium. Repeated subcultures affected both multiplication and hyperhydricity. The multiplication of shoots increased from parental culture up to 5th subculture and thereafter declined in 6th subculture. Although shoot hyperhydricity were observed from 1st subculture (19%) and then increased up to 85% in 6th subculture. This increased in hyperhydricity could be due to the remaining influence of hormones. In shoots of 5th subculture the content of chlorophyll (dark green) were higher than shoots of 6th subculture.

Bio-stimulants are in excessive demand for the sustainable production of floriculture crops. The current investigation was designed to find out the effect of naturally occurring growth stimulant moringa leaf extract (MLE) on the growth, flowering, post-harvest life and corm production of two gladiolus cultivars (cvs.) ‘Rose Supreme’ and ‘White Prosperity’. The research trial was laid out in the factorial arrangement under randomized complete block design. Corms were grown in the open field under local climatic conditions of Faisalabad, Pakistan. Potential of exogenously applied (MLE; 30 times diluted) was evaluated. Treatments including spraying MLE at 3 leaves, 5 leaves, floral bud stage, one combination of these three stages relative to control with no foliar application. Application of natural bio-stimulant produced maximum height in both cvs. against T4. Both cvs. gave maximum stalk length in response to T4. The number of florets spike–1 found the maximum (13) in T1 compared to control T0 which yield (9) florets. Maximum vase life in sucrose solution (13.33 days) was exhibited by T1 for both cvs. while minimum (10 days) in T0. In cultivar comparison earlier spike emergence was observed in ‘White Prosperity’. In ‘Rose Supreme’ maximum corm weight was attained in response to T3 (43.43 g) while minimum (30.33 g) in T0.‘White Prosperity’ produced maximum weight (40.33 g) against T4 whereas minimum by control. The cultivar mean comparison showed the superiority of cormel diameter in ‘Rose Supreme’ (10.93 mm) than ‘White Prosperity’ (9.13 mm). In treatment comparison, T4 produced maximum diameter (12.04 mm) in ‘Rose Supreme’ moreover, T2 induced maximum (9.57 mm) diameter in ‘White Prosperity’.

Opis:
Xeriscaping focus on the use of drought tolerant species of plants for environmental sustainability leading to the conservation of natural resources. We need to look for drought tolerant, water efficient plant species. Present research was aimed to assess the water use efficiency of Leucophyllum frutescens (silvery) for its adaptability and potential as xerophyte. In this study, seven treatments were applied were 100% field capacity was considered as control while 85%, 70%, 55%, 40%, 25% and 5% field capacities were taken as different drought levels. Effect of drought commenced at 40% field capacity and lower drought treatments as decrease in shoot and root fresh and dry weight, root length, leaf area and leaf area index and leaf firing percentage increased with severity of drought compared to 100% field capacity. Physiological parameters including water use efficiency (A/E), leaf water potential (ψleaf), stomatal conductance (gs), photosynthesis rate, cell membrane stability and total chlorophyll contents proved that this plant species can tolerate severe drought conditions. Positive correlation was found among most of the attributes but leaf temperature was negatively correlated with leaf water potential, photosynthesis rate, cell membrane stability, and chlorophyll contents. Moreover, regression analysis between various morphological and physiological attributes showed the predictive power of the model yielding significant results for leaf area and cell membrane stability (R2 = 0.74), root length and photosynthesis rate (R2 = 0.65), leaf temperature and chlorophyll contents (R2 = 0.43) and leaf area and leaf water potential (ψleaf) (R2 = 0.93).

Opis:
Rotating machinery plays a significant role in industrial applications and covers a wide range of mechanical equipment. A vibration analysis using signal processing techniques is generally conducted for condition monitoring of rotary machinery and engineering structures in order to prevent failure, reduce maintenance cost and to enhance the reliability of the system. Empirical mode decomposition (EMD) is amongst the most substantial non-linear and non-stationary signal processing techniques and it has been widely utilized for fault detection in rotary machinery. This paper presents the EMD, time waveform and power spectrum density (PSD) analysis for localized spur gear fault detection. Initially, the test model was developed for the vibration analysis of single tooth breakage of spur gear at different RPMs and then specific fault was introduced in driven gear under different damage conditions. The data, recorded by means of a wireless tri-axial accelerometer, was then analyzed using EMD and PSD techniques and the results were plotted. The results depicted that EMD algorithms are found to be more functional than the ordinarily used PSD and time waveform techniques.
