The purpose of this study was to design a paper strip-based non-invasive urine analysis system for the qualitative detection of biomarker aquaporin-1 (AQP1) in renal cancer (RC). RC accounts for 3% of all cancers and 85% of all kidney tumors and mainly originates from the kidney cortex. In recent times, higher urine concentration of AQP1 in patients with RC was confirmed as a specific biomarker of the disease. Hence, the noninvasive, user-friendly and self-diagnostic method is required for the detection of aquaporin biomarkers in RC.

The present research work was focused on the development and characterization of a dye conjugated cyclodextrin-based miniaturized system for impregnation on Whatman filter paper to identify RC using AQP1 biomarker present in urine samples.

It was observed that the test strip dipped into the urine sample, and the yellow color intensity increased with a decrease in AQP1 concentration due to the transformation of the dye system of free basic form into bound acidic form. The Hue-Saturation-Value profiling was used to observe the effect of color change using a smartphone application. The paper strip-based urine analysis system is highly sensitive for the detection of AQP1 in the range of 10 to 1,000 ng.

The successful validation indicated that this biosensor is likely to contribute to the development of point-of-care, novel, personalized diagnostics and ensure prolonged survival of RC patients in the near future.

SO much controversy has raged around the subject of newsrooms in the past two years, that librarians are, as a rule, utterly tired of it, and the appearance of still another article upon the subject is not calculated to tone down the general spirit of vexation. It requires no little courage to appear in the arena in this year of Grace, openly championing those departments of our institutions which were originally intended to convey the news of the day in the broadest manner.

This paper aims to present the work and contributions of Karol Adamiecki in comparison with Frederick Winslow Taylor and discusses the various contexts in which both scholars conducted their research. The purpose of this study is bring to light some of the main accomplishments of Adamiecki and contribute to the discussion of reasons why the work of some scholars draws wide acclaim, while similar work of others remains unnoticed.

The background for the discussion is the work and ideas of Karol Adamiecki, a Polish engineer and manager, whose methods and findings were similar to those of Frederick Taylor and are contemporary, and, in some cases, precede those of the Father of Scientific Management. The methodology used in this study is a review of the original work of Adamiecki and Taylor to find the true meaning and purpose behind their writings, as well as a review of relevant literature regarding the context of the realities in which both scholars constructed their research.

The concepts and inventions of Karol Adamiecki are, in many aspects, similar to those of Frederick Taylor and his followers. Several factors are identified and discussed which may have influenced the varied level of recognition of conceptually similar ideas evolved in different parts of the world. These factors are, among others, the socio-political reality of Eastern Europe and Poland under the influence of Russia and the Soviets as compared to that of the USA and the Western World and the support of various interest groups and government institutions, as well as the impact of the academic circles.

In today’s world of globalization reaching all aspects of life, it is necessary to recognize and acknowledge the developments emerging in different settings, regions and cultures. Furthermore, the social and political realities in which research is constructed may impact the future acceptance, dissemination and popularity of the findings and authors.

Although some research exists outlining the work of Adamiecki, this study contributes to the body of historical management knowledge by focusing on the main accomplishments of Adamiecki based on his original writings and placing his accomplishments in a historical context in comparison to Taylor, thus analyzing the reasons for the lack of wider acclaim for Adamiecki’s contribution to scientific management.

Knowledge concerning the meaning of the object of learning is an important contribution of Learning study. The purpose of this paper is to generate this kind of knowledge and show how it can be developed and refined in the different phases of a Learning study.

The paper reports on a Learning study in primary technology education conducted with students aged six to seven years old, with the aim to explore a specific object of learning; to construct a linkage mechanism for transferring and transforming movement.

The findings show several aspects to discern by the learner in order to grasp the object of learning and reveal how this knowledge was gradually developed during the Learning study. The presumed aspects, those identified in the pre- and post-test, as well as how they were elaborated in the lesson contributed to refining the meaning of the object of learning.

In Learning study, knowledge concerning the meaning of the object of learning is generated. By empirically demonstrating the development and specification of this knowledge during a Learning study, this paper will contribute to the discussion of knowledge products from Learning studies as well as to knowledge concerning what there is to know in order to develop a specific capability in technology education.

The textile industry is one of the largest and most important industrial sectors in India. Because the textile industry consumes large quantities of water and produces highly polluted water discharge, its environmental impact is high. Water is expensive to use, treat and dispose of. Therefore, water conservation and reuse are critical necessity for the textile industry because decreasing water and wastewater treatment and recycling costs can be beneficial.

This research neutralized the pH during dyeing industry wastewater treatment. The system should be robust to erroneous sensor measurements. A pH meter was developed and used to monitor the pH of wastewater hourly before and after HCl treatment.

HCl was used to neutralize the pH of wastewater from 9 to 7.5. The amount of HCl was optimized depending on the wastewater. Three wastewater treatment methods were used, namely, HCl, wash water and reverse osmosis (RO) treatments. The HCl treatment was the most effective for decreasing the pH; the wash water treatment was the most effective for decreasing the total dissolved solids (TDS), total suspended solids (TSS) total hardness and chemical oxygen demand; and the RO treatment was the most effective for decreasing the biochemical oxygen demand, TDS, TSS, total hardness and Cl⁻ concentration.

The pH should be monitored during the textile dyeing because the addition of color to textile fabrics is the most effective at neutral pH. This study evaluated several parameters of wastewater, including pH, color, TSS and TDS. The fabricated digital pH meter provided superior results than conventional measuring devices. The goal was to maintain a neutral pH during dyeing and recycle wastewater to improve environmental sustainability. The newly developed digital pH meter was less expensive and more precise than traditional pH meters. Before reusing and recycling, wastewater underwent ultrafiltration and RO treatment.

In recent work on the preparation of small samples of dye dispersions, a simple method has been developed of quantifying particle sizes and stability in dispersion. A method sometimes used by laboratories is to spot a filter paper with a dilute dispersion and observing the lateral spread of the dye or pigment. Particles lacking adequate stabilisation will tend to be precipitated near the centre of the spot, the carrier medium spreading out to leave a translucent halo. It is considered that precipitation is caused by the electrostatic charges on the fibres of the filter paper. This method can, in many instances, offer a guide to the quality of the dispersion, but an objection is that the results embody variable causative factors, making the test subjective and unless great care is taken, the test may fail to answer the criterion of repeatability and reproducibility. The authors have found that a dispersion with particles of dye with a medium size of one micron show vigorous Brownian motion over several hours of storage time and yet the sample offers anomalous results with a spot test on filter paper.

THE application of cemented wires to determine the location of initial failure in static tests on large specimens has been investigated, among others, by R. W. Powell in 1946.
