The most outstanding problem militating the production of earth block in Nigeria, is the exorbitant prices of cement, rice ash replaced with cement, stabilized compressed earth block to carry load. The main objective of this study was to investigate the sustainability of earthen construction block with a partial replacement of cement using Rice Husk Ash (RHA). RHA is a bye-product material obtained from the combustion of rice husk which consists of non-crystalline silicon dioxide with high specific surface area and high pozzolanic reactivity using a set of sieves 3.35um - 63um, weigh balance, oven maintained at a temperature of 105°C and 110°C, six meta trays, a bucket, a soap, wire brushes, and a mechanical shaker. It is used as pozzolanic material in earth block. Testing specimen were determined and examine in structural composition by means of unconfined compressive strength hydraulically compressed for crushing the composition of mix with RHA content ranges from 10% to 50% to respectively. The result of the compressed earth block shows a significant resistance of shear strength of 30 to 90 kg/mm2, proving that stabilized earth block can satisfactorily carry load when structurally loaded and can resist tensile and compressive stresses.

The term “Stress-Strength reliability” means , where a system or an equipment with random strength X is subjected to random stress Y in a way that system breaks down, if the stress surpasses the strength. In this paper, a system is considered with standby redundancy, and it is presumed that the distinct components in the system for both stress and strength variables are independent and have different probability distributions viz. M- Transformed Exponential, Exponential, Gamma and Lindley. The expressions for the marginal reliabilities  etc. based on its stress-strength models are obtained.

This paper presents a Cuckoo Search (CS) algorithm-based methodology for simultaneous optimal placement and sizing of Shunt Capacitors (SCs) and Distributed Generations (DGs) together in radial distribution systems. The objectives of the work are to minimize the real power and reactive power losses while maximizing the voltage stability index of the distribution network subjected to equality and inequality constraints. Different operational test cases are considered namely installation of SCs only, DGs only, SCs before DGs, DGs before SCs, and SCs and DGs at one time. The proposed method has been demonstrated on standard IEEE 33-bus and a practical Ayepe 34-bus radial distribution test systems. The highest percentage power loss reduction of 94.4% and other substantial benefits are obtained when SCs and DGs are optimally installed simultaneously. Simulated results obtained from the proposed technique are compared with other well-known optimization algorithms and found to be more effective.

The present investigation was carried out to study the performance of yield and growth parameters of tomato crop under different mulching materials. This experiment was conducted at Vikas College of Engineering and Technology, Nunna, Vijayawada during the period from Jan 2020 to April 2020. The experimental field has an area of 180 m2 (15m × 12m) and divided into 4 plots i.e., Drip with plastic mulch (A), Drip with live mulch (coconut coir) (S), Drip without mulch (M) and Control (without mulch and without drip) (K). Growth parameters like plant height, number of leaves per plant, soil parameters like bulk density, soil temperature, soil moisture and yield were observed for each treatment. Crop water requirement was calculated using CROPWAT 8.0. The results showed that the bulk density has no effect between the treatment plots. The soil moisture in initial stage is more in K and least in S; in flowering stage, M was high and least in K and in harvesting stage, it is high in A. The soil temperature was high in K and least in A. The readings of number of leaves was observed high in A and least in K. It was observed that highest yield was obtained in A and least in K. The weed control efficiency was found to be highest in A (57%) followed by S (41.3%) and weed control efficiency was lowest in M (22.8%).

The thermal behavior of air by natural convection in a confined trapezoidal cavity, one of the walls of which is subjected to a constant heat flow in hot climates, has been analyzed numerically. The heat and mass transfers are carried out by the classical equations of natural convection. These equations are discretized using the Finite Difference Method and the algebraic systems of equations thus obtained are solved with the Thomas and Gauss algorithms. We analyze the influence of the number on the current and isothermal lines as well as the effects of the aspect ratio A = l / H and the angle of inclination φ. In particular, we have shown that convective exchanges in the cavity are preponderant for high Ra numbers. Also we have watches the increase in the values ​​of the isothermal lines and the decrease in the intensity of the streamlines for the low values ​​of A and of the angle φ.

Combining ability study on seed yield per plant from a 7x 7 half-diallel cross of sesame over two years showed that both general combining ability (gca) and specific combining ability (sca) variances important for controlling the traits. Thus, the objectives of this study were to evaluate the gene action and select appropriate parents/crosses using combining ability analysis. Both additive and non additive was of greater significance for seed yield per plant, capsules per plant, days to flowering and oil content. Non additive genetic variances were in the genetic for 1000 seed weight and branches per plant. On the contrary preponderance of additive genetic was found in the inheritance of capsule length and seeds per capsule. The relative magnitude non-additive year interaction was larger than additive x year interaction. The variety Suprava was the best general combiner for seed yield and its major components except oil content. The cross combinations Suprava x Savitri, Suprava x JLT 408 and EC 90 x Savitri would be the best choices for obtaining desirable recombinants. Suprava x Savitri having additive gene control emerged as the best specific combiner for yield and its components except oil content. For improving seed yield and oil content simultaneously, the specific combiner IC 59 x Savitri was identified to be ideal as this cross mostly controlled by additive gene action and hence desirable recombinants can be obtained in early segregating generation. Breeding strategy for different crosses has been discussed in details. The information could help sesame breeders for appropriate selection of parents with high yield potential and oil content to develop future hybridization programs.

Millets are the 5th most important cereals in the world after wheat, maize, rice and barley. It is a minor cereal containing abundant of nutrients but its consumption is lacking to a certain extent mainly due to the lack of ready-to-cook or ready-to-eat products and processing of millet to prepare ready to cook (RTC) foods can increase its economic and nutritional value. The processing, physical, chemical and nutritional aspects were analysed against the commercially available foxtail and proso flakes to standardise. The decorticated grains were steeped in 5 L of potable water at ambient conditions (30 ± 2ºC) for 10 hr, autoclaved at 180ºC under the pressure of 20 to 24 lbs/psi for 10 min dried at 50ºC in a mechanical dryer to 18 ± 1% moisture content. The processed grains were rolled to flakes in a heavy-duty roller flakes machine with an aperture size of 0.25 mm. The commercial foxtail and proso flakes had higher values for all physical parameters than standardised ones.
