Section 5. Tables of Suggested Water Chemistry Targets

Consensus water chemistry controls for the six types of steam generator systems are presented in Tables 1 through 7. The tabulated information is categorized according to operating pressure ranges because this is the prime factor that dictates the type of internal water chemistry employed, the normal cycles of feedwater concentration, the silica volatility, and the carryover tendency. The difference between steam and water densities decreases with increasing pressure and temperature; therefore, separating the steam/water phases completely in the boiler drum becomes increasingly difficult to achieve. Since the tendency to carryover is greater at higher operating pressures, it is necessary to maintain lower boiler water contaminant concentrations to meet the same steam purity target.

The sub-class sizes of some elements being square free

Let [Formula: see text] be an element of a finite group [Formula: see text], and [Formula: see text] a prime factor of the order of [Formula: see text]. It is clear that there always exists a unique minimal subnormal subgroup containing [Formula: see text], say [Formula: see text]. We call the conjugacy class of [Formula: see text] in [Formula: see text] the sub-class of [Formula: see text] in [Formula: see text], see [G. Qian and Y. Yang, On sub-class sizes of finite groups, J. Aust. Math. Soc. (2020) 402–411]. In this paper, assume that [Formula: see text] is the product of the subgroups [Formula: see text] and [Formula: see text], we investigate the solvability, [Formula: see text]-nilpotence and supersolvability of the group [Formula: see text] under the condition that the sub-class sizes of prime power order elements in [Formula: see text] are [Formula: see text] free, [Formula: see text] free and square free, respectively, so that some known results relevant to conjugacy class sizes are generalized.

University Student Engagement Scale: Development and Validation in Indian Context

In academic achievement, student engagement is considered a prime factor to enhance motivation among students. Student engagement is a constructive approach that refers to the level of concentration, inquisitiveness, and enthusiasm that students demonstrate when they learn. The study aims to elucidate the development of a three-dimensional construct of student engagement based on psycho-education oriented measures such as behavioural, cognitive and emotional engagement. Data from 470 students studying in science, humanities, and engineering streams from different universities of Punjab, was collected via random sampling technique. The factor analysis of the scale reveals that 31 items had three factors, behavioural, cognitive, and affective engagement. Good internal reliability (????=0.889) and adequate convergent and discriminant validities are reported, which establishes good psychometric properties of the scale.

A review of wear resistance materials used in power-screw mechanism for aerospace applications

In today’s industrial requirement, good wear resistant materials with the same or better mechanical properties are the need of the hour. In the present paper, an actuator that is used to lift the load is under study. It uses a linear actuation mechanism involving a screw-like motion to lift the loads. It employs a stainless steel of high quality. Since there are various types of wearing involved in the system, choice of the materials becomes the prime factor for determining the maintenance cost and the cycle life of the actuator. There are many research advances made in this field which provides us with the best type of material for its particular type of job. The present paper discusses the materials that could be substituted in place of the existing material choice i.e., in place of AMS5659 and aluminium-bronze. The two materials stated above are known for its superior wear handling and excellent mechanical properties.

A CLINICAL STUDY TO EVALUATE THE EFFICACY OF GUDUCHYADI TAILA MATRABASTI IN VANDHYATWA W.S.R. TO ENDOMETRIAL RECEPTIVITY

Infertility is a public health issue in India and many other developing countries because of its high prevalence and especially due to its serious social implications. According to the data of WHO, more than 180 million couples in developing countries agonise from primary or secondary infertility. The social stigma of childlessness still leads to isolation and abandonment in many communities. Although there is a lot of advancement in infertility care, the availability, affordability and effectiveness are still very low. Ayurveda described the disease vandhyatwa as equivalent to infertility. In Ayurveda, the management of Vandhyatwa mainly focuses on the correction of garbha sambahava samagris. Kshetra which is one among them is considered as the prime factor for conception. Kshet- ra can be taken as the female reproductive system, a well-prepared endometrium for implantation. Optimal en- dometrial receptivity leads to proper implantation of the embryo, which is the foundation of a healthy pregnancy. Implantation failure due to reduced endometrial receptivity is one of the major causes of infertility. In this present study, the endometrial receptivity was assessed with Applebaum's uterine score and Guduchyadi taila matrabasti has been administered to increase the receptivity of the endometrium. After the intervention, the results obtained showed significant improvement in endometrial receptivity. Keywords: Vandhyatwa, Applebaum's scoring, Matrabasti, Guduchyadi taila

«On the Model of the Grand Duchy of Lithuania»: Prospects of Integration of Cossack Ukraine into Compound of the Polish-Lithuanian Commonwealth in 1658–1659 (Expectations and Realities)

The article explores the discursive questions connected with the preparation and conclusion of the Ukrainian-Polish treaty of Hadiach in 1658. In particular, the content of the agreement and factors that led to the fact that the idea of the Hadiach treaty (realignment of the Commonwealth into a state of three nationalities) remained unrealised are analysed. The attention was paid to the fact that Polish-Ukrainian negotiations and the conclusion of the agreement in the set near Hadiach in 1658 were conditioned by a number of factors relating to the current Ukrainian-Polish, Ukrainian-Moscow and Polish-Moscow relations. The prime factor that made the Hetman’s government of Ivan Vyhovsky negotiate with the authorities of the Polish-Lithuanian Commonwealth was the fact that it looked for a medium of reconciliation and further state development of Ukraine because there was a growing threat from Moscow. In Warsaw, in return, having made the most from the dire situation of Ukraine, the authorities longed for solving the “Ukrainian question” by the peaceful return of the lost Ukrainian territories in 1648. They also hoped that in the context of successful development of negotiations with Chigirin, it would be possible to get an advantage over Moscow in the long-running confrontation over dominance in CEE. The content of the treaty of Hadiach that was worked out during the long negotiations mirrored the trend when the Ukrainian part, which was more interested and acted with a weak diplomatic hand, had to agree to the terms dictated by Warsaw. Although, in general, the position of Ukraine in the reformed Polish-Lithuanian Commonwealth should have resembled the position of Lithuania, Chigirin was forced to accept territorial restrictions, Warsaw's refusal to liquidate the church union, and so on. The author concluded that the prime factor, which eventually led to the collapse of the idea of Hadiach, was the reluctance of the Polish political elite to recognise equal rights for Ukraine and the Cossacks, and the fact that Warsaw sleepwalked when Moscow troops invaded Ukraine and Hetman Vyhovsky desperately needed the promised help.

Contributing and Influencing Factors on Organic Agriculture Practices by Farmers in Tamil Nadu, India- An Analysis

The goal of this study is to find factors that influence the adoption of organic farming. The study’s objective necessitates the selection of an organic agricultural district. The study was conducted in Tamil Nadu’s western region on purpose with 180 farmers. The most effective elements found in the current study to determine the factors affecting the adoption of organic farming in Tamil Nadu are Organic farm perception potential (Prime factor) with Eigenvalue 3.854. Since, organic farming experience (X5), scientific approach (X12), animal ownership (X13), perceptions of organic manure utilization (X15), and perceptions of organic farming profitability (X16). With the highest factor loading of the above-mentioned factors of 0.689, 0.602, 0.206, 0.591, and 0.613, it has a stronger influence on the amount of adoption of organic farming practices in Tamil Nadu’s Western zone. As a result, farmers should be motivated and educated about the benefits of organic farming through extension and research institutes, not only to improve income but also to modify their behaviour and perceptions about new agricultural techniques.

When the Robin inequality does not hold

In mathematics, the Riemann Hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part $\frac{1}{2}$. It is one of the seven Millennium Prize Problems selected by the Clay Mathematics Institute to carry a US 1,000,000 prize for the first correct solution. In 1915, Ramanujan proved that under the assumption of the Riemann Hypothesis, the inequality $\sigma(n)<e^{\gamma }\timesn\times\log\log n$ holds for all sufficiently large $n$, where $\sigma(n)$ is the sum-of-divisors function and $\gamma\approx0.57721$ is the Euler-Mascheroni constant. In 1984, Guy Robin proved that the inequality is true for all $n>5040$ if and only if the Riemann Hypothesis is true. Let $n>5040$ be $n=r\timesq$, where $q$ denotes the largest prime factor of $n$. If $n>5040$ is the smallest number such that Robin inequality does not hold, then we show the following inequality is also satisfied: $\sqrt[q]{e}+\frac{\log\log r}{\log\log n}>2$.
