Abstract The crack growth behavior of a non-crystallizing rubber, SBR, is investigated in terms of the tearing energy T, the energy available for crack growth. For cyclic deformations in which the minimum tearing energy is zero (relaxing conditions), a unique relationship is obtained between the growth per cycle and T at the maximum deformation. This rubber also exhibits crack growth at constant tearing energies. The relationship of the crack growth rate as a function of tearing energy, when the minimum tearing energy of the cycle is not zero, can be superimposed on the relaxing relationship by scaling the rates, and a tentative explanation is proposed for the scaling factor. Fatigue data are consistent with this.

Purpose – The purpose of this paper is to present ways for managers to attain the phenomenological attitude. Achieving effective communication in organizations like libraries and information agencies is a difficult challenge. The business literature offers some suggestions, but those fall short. Application of phenomenological methods by managers can help meet the challenge and bring people together around the intended messages. Design/methodology/approach – Of utmost importance to effective communication is transcending what can be called the “natural attitude” in favor of the “phenomenological attitude”. This requires recognition by managers of the unique relationship of self and other, plus the realization that action is intentional (meaning that being conscious means being conscious of something). This paper presents ways for managers to attain the phenomenological attitude. Findings – Phenomenological methods of communicating have the potential to engage and involve everyone in the organization by enabling all to comprehend fully the nature of what is communicated and what is to be accomplished. Originality/value – Phenomenology is seldom applied to organizational communication; this paper demonstrates that it presented the wherewithal to help managers improve the effectiveness of libraries and information agencies.

SUMMARYDrought is the main factor limiting the productivity of crops in Mediterranean areas. The introduction of physiological traits into crops that improve their tolerance to drought is necessary if yields under these conditions are to be efficiently improved. The effect of drought on different gas exchange variables, i.e. net photosynthesis (A), stomatal conductance (gs) and leaf chlorophyll concentration (Chl), and the relationship of these variables with yield were studied in 12 barley genotypes grown under irrigated and terminal drought conditions. The variable most sensitive to water deficit was gs (mean reduction 43% with respect to control conditions), followed by A (mean reduction 34%). The mean reduction of yield by terminal drought was 27%. A significant correlation was seen between these physiological traits and yield. The effect of water deficit on A, gs and Chl was smaller in the breeding lines than in the traditional varieties assayed, in agreement with the results found for yield. These results suggest a potential indirect selection of physiological characteristics in these breeding lines that allow greater tolerance to drought. The response of the different genotypes examined was not homogeneous across all the variables analysed. This variability is important in programmes aiming to obtain drought-tolerant genotypes via the optimization of traits such as those above.

This study analyzed the relationship between Covid-19 response strategies and employees Faith in chosen Hotels inside Eastern NCR Region. The crosssectional study conϑiguration was received and information was produced from 144 employees chose utilizing the basic simple random sampling from a populace of 242 workers of ϑive chose Hotels in Eastern NCR Region. The examination, being prevalently nomothetic in the system, observationally discovers the unique relationship of two distinguished experimentally referents of the indicator variable, Covid-19 response strategies, in particular; Communication & monitoring with the model variable, representative Faith utilizing the Spearman’s rank order correlation measurable tool. The information assortment instrument comprised of the poll with discoveries uncovering that Covid-19 response strategies, such as, Communication & monitoring essentially associate with worker Faith. In light of these discoveries, it was inferred that Effective and transparent communication and monitoring systems and exercises altogether improve representative Faith in associations and from that point we suggested that associations, particularly Hotels, Adopt more transparent and practical approach which translate conϑidence and competency on their part especially in given crises situation such as COVID 19. The executives ought to likewise try to empower and console staff, clients, and different partners of their pledge to guarantee the security and prosperity of every single invested individual during and signiϑicantly after crises as this would Further promote Faith and in this manner empower a progressively helpful work environment.

In the course of investigation into the operating economics of transport aircraft, the cruising speed arises as a fundamental variable and a rapid method of correction of speed for variation of power, height and weight is frequently required. Other problems present themselves, such as the estimate of cruising speeds in the course of a new type design study, or the correction of a “one–point” published performance of a new aircraft to a standard operational condition differing in specified weight, altitude or power output for cruising.In this note no account will be taken of the block speed correction arising because of the modification of true air speed by the various factors, such as wind, climb and glide which distort the optimum flight path. The principle of the method here suggested involves the unique relationship of p, the ratio of thrust power required at any speed (V) to the thrust power at the minimum drag speed (u) at the same altitude, and n the wellknown speed ratio V/u.
