The article introduces the professional activities of Latvian-born Lithuanian architect and engineer Karolis Reisonas (in Latvian: Kārlis Reisons; 1894–1981) in the second half of his life – from 1930 in Kaunas, Panevėžys and Adelaide cities – and his role in the history of Lithuanian architecture. K. Reisonas was one of the most prominent creators of modern 20th-century interwar Lithuanian architecture and together with other famous Lithuanian architects formed a special style of Kaunas modern architecture in interwar period. K. Reisonas is the author or co-author of representative buildings in Šiauliai, Kaunas and other Lithuanian cities, as well as in Riga and Adelaide cities. Architect and engineer K. Reisonas worked as Šiauliai City Engineer and Head of Municipal Construction Department (1922–1930), Director of Šiauliai Vocational School (1926), Consultant of Lithuanian Chamber of Agriculture (1927–1928), Head of Construction Department of Kaunas Municipality (1930– 1938), Panevėžys City Engineer (1940) and Burgomaster (1941–1944). From 1949, the Reisonas family lived in Adelaide city, Australia. To his projects three monuments of independence were built in Lithuania – Monument of Independence in Šiauliai city, Podium of the Freedom Monument of Kaunas city and Roman Catholic Christ’s Resurrection Church in Kaunas city. Fourteen of buildings in Lithuania (in Kaunas and Šiauliai cities) designed by him are included in the list of cultural values of Lithuania. Early K. Reisonas’ projects are characterized by historism, elements of eclecticism and «brick style», later projects are characterized by austere rationalism, functionalism, adaptation to urban construction and cultural and historical context.

Dilip Roy is a country head at Itsun Heavy Industry (India) Pvt. Ltd. (IHIIPL) in Delhi, India. It is a wholly owned subsidiary of Itsun China, a leading private sector construction equipment company. Dilip graduated as a mechanical engineer with reputed National Science Talent Search Scholarship, started his career as a Graduate Trainee Engineer and became a Vice President in another company before he joined IHIIPL as a country head. Hu, the representative of Itsun China in India was exploring the Indian market and he ended up offering a job to Dilip after a series of interactions concerning the Indian Construction Equipment Industry. This was the first opportunity for Dilip to head an entire company. He knew the industry thoroughly and felt excited that finally his ambition was at the verge of fulfillment. When Dilip joined, IHIPL had yet to be incorporated though some business activities had started. Dilip's time at IHIIPL is dotted with problem after problem. The key problems encountered were confusion about reporting relationships, unresponsive head office with its unilateral decisions, and unprofessional and incompetent colleagues. Dilip had taken steps to address most of the company's problems: developing local solutions, drawing on personal resources, and hiring new staff. The business was growing fast on the back of increasing demand. Subsequently, Dilip realized that he was not considered trustworthy by the head office and was not involved in major decisions. His initial perception about his job and IHIIPL changed. Even though he was later given the certificate of honor with an invitation to attend the award ceremony in China, he left the company. This case is useful for examining the issues of cross-cultural management and leadership.

The present paper deals with the structural analysis and the re-design of a cutting head for an automatic crosscutting machine. The machine is already marketed, and can process rectangular section wooden slats. The principal goal of this work is to develop a new mechanism capable of enhancing the productivity of the machine by around 80%. The work has been carried out by means of both numerical finite element analysis tools and analytical models. In fact, a secondary aim of the research is to define an analytical model which can capture the dynamic behavior of the device: this tool will be helpful to the design engineer in order to save costs associated with the development of future head designs.

Of the many talented men who entered government service in Egypt in the 19th century, none equaled in sheer energy and productivity ʿAli Mubarak Pasha (1823/4–1893). Engineer, officer, administrator, educator, and author, he was the outstanding Egyptian of his generation and the first native Muslim to head a government department in modern times. Yet his most enduring legacy are his writings, in particular his famous Khitat. A twenty-volume topographical encyclopedia published in the 1880s, the Khitat of ʿAli Mubarak is a landmark of Arabic prose and probably constitutes the greatest existing historical record of Egyptian society.

A numerical model of beach topography evolution was developed. The model includes five sub-models: random wave transformation model, surface roller model, wave-induced current model, sediment transport model, and morphological change model. The model was validated by two unique high-quality data sets obtained from experiments on the morphological impact of a detached breakwater and a T-head groin in the basin of the Large-scale Sediment Transport Facility (LSTF) at the US Army Corps of Engineer Research and Development Center in Vicksburg, Miss. The simulations demonstrated that the model well reproduced the wave conditions, wave-induced currents, and morphological evolution in the vicinity of the structures.

Planners of San Francisco’s 1915 Panama-Pacific International Exposition wanted to present their city as the center of an American empire that stretched from Maine to the Philippines. The fair’s head landscape engineer John McLaren and his team spent three years planning and planting the fairgrounds to reinforce this message. They used plants and flowers from around the world to show off California’s gentle climate, and convey to visitors the idea that the city was at the center of the commercial world. This article details the work that McLaren’s crews undertook, analyzes three sections of the fairgrounds, and discusses the impact the fair’s landscaping made on visitors.

The primary objective of this study was to design the optimal geometry of a novel screwdriver, create the grooves on a ball head screw, and demonstrate its resistance to a torque of up to 40 Ncm at angulations of 0°, 15°, and 30° by using nonlinear finite element analysis. A secondary objective was to create a foolproof, easily recognizable system. The grooved ball head screw and geometry of the screwdriver, functioning from an angulation of 0° to 30°, was generated using Pro-ENGINEER Wildfire 5.0 software. Static structural analyses among bodies in contact were performed at different angles of 0°, 15°, and 30° at a torque of 20 Ncm and 40 Ncm using nonlinear finite element simulation by means of ANSYS 12.0. The maximum stress supported by the ball head screw and screwdriver was similar at 20 Ncm and 40 Ncm. Although greater deformations were found at 40 Ncm, these were small and might not affect the performance of the system. Further, the rupture torque value for the M2 connection was 55 Ncm for 0° and 30°, and 47.5 Ncm for 15°. Numerical simulation showed that the ball head system design can achieve the mechanical strength requirements expected for screws used in implant-supported restorations at an angulation of up to 30°. Finite element analysis showed this novel ball head screw and screwdriver system to be a good solution for angled screw channels in implant-supported prostheses.

The primary purpose of water aeration is to increase the oxygen saturation of the water. This can be achieved by using hydraulic structures because of substantial air bubble entrainment at these structures. Closed conduit aeration is a particular instance of this. While there has been a great deal of research on air-demand ratio within closed conduit, very little research has specifically addressed aeration efficiency of closed conduit. In the present work an experimental study was conducted to investigate the aeration efficiency of high-head gated circular conduits. Results showed that high-head gated circular conduits were effective for oxygen transfer. The effects of Froude number and ratio of the water cross-sectional flow area to the conduit cross-sectional area on aeration efficiency were particularly significant, whereas the effect of conduit length was only moderate. Further, a design formula for the aeration efficiency was presented relating the aeration efficiency to ratio of water cross-sectional flow area to conduit cross-sectional area and Froude number. The obtained results will be useful in future modeling processes and aid the practicing engineer in predicting aeration efficiency for design purposes.

This year marks 85 years of the National Research University “Moscow Power Engineering Institute” (National Research University "MPEI”). The department of engineering drawing was the first among other departments in the MEI, for which it is also the anniversary year. The organizer and the first head of this department from 1930 to 1962 was Eugeniy A. Glazunov - a prominent scientist and educator, engineer and organizer, who celebrates 125 years. At the beginning of 1930 the Department of Electrical Engineering Higher Technical School, which earlier E.A. Glazunov graduated, has been transformed into the Moscow Higher School of Energy, which became soon the Moscow Energy Institute. Eugeniy Glazunov was appointed to the head of the department of descriptive geometry and drawing in MPEI. (Some time this department was called "Technical graphics"). His name is undeservedly rarely mentioned in textbooks and other literature in applied geometry and graphics. But Eugeniy Glazunov was very authoritative in the circle geometry and graphics, and among the heads of departments he was one of the initiators and leaders of the Moscow seminar on descriptive geometry, who published his works, and the head of the department, who generously shared teaching materials with his related institution. But E.A. Glazunov had relatively few publications compared with present time. But there were very capital works. One of them was written in conjunction with the N.F. Chetverukhin and is called "Axonometry." But it was not only an outstanding organizer and teacher, but also a magnitude engineer — designer and practitioner in the field of electrical engineering. He was a team-mate, who developed and marketed the first installation, substation and network of well-known Russian electrification plan — the plan for electrification. Based on his experience and under his leadership tasks on the engineering drawing based on electrical products and parts were improved, and drawing ceased to be exclusively machine-building. His merits in the development of engineering education and his geometry and graphic component were so significant that he was awarded the title of professorship of Higher Attestation Commission without doctoral dissertation. He was also one of the highest awards of that time, the Order of Lenin (1951).

The research reveals facts about the family of engineer Jānis Jagars (1894–1970) and the versatility of his work in the 20th century. He studied at Riga Polytechnic Institute (RPI) and stayed in Russia during World War I. After returning to Latvia in the beginning of 1919, he graduated from the Baltic Technical University (BTU; Baltische Technische Hochschule, also Baltic Higher Technical School), which was established on the basis of RPI. J. Jagars participated in the activities of the Latvian Social Democratic Workers’ Party (LSDWP), which supported his becoming the Head of the Riga City Construction Board. After the coup organized by Kārlis Ulmanis (1877–1942) he was arrested, then – released, after which he headed an engineering office. In June 1940, he joined the government headed by Augusts Kirhenšteins (1872–1963), where he held the position of Minister of Transport. He evacuated to the Soviet Russia during World War II. After the war, J. Jagars was an Assistant Professor at the State University of Latvia (SUL) and worked in various construction design institutes.

Abstract The calculation of the friction factor involved in the Darcy-Weisbach equation has a key role in the accurate assessment of distributed head losses. For the turbulent flow regime, this friction factor was mathematically expressed in the form of the Colebrook-White (C-W) equation, widely accepted by engineers and scientists. Nevertheless, the C-W equation is an implicit one and must be solved using numerical methods. This is a major disadvantage for the average engineer, who always prefers an explicit equation which could be easily integrated into his familiar spreadsheet environment. The present paper is investigating some of the most used explicit alternatives to the C-W equation, with respect to several case scenarios taken from typical Building Services hydraulic calculations.

On November 16, 2020, an outstanding Russian seismologist Aleksey Illarionovich Ivashchenko passed away from the severe form of COVID-19. For 40 years of work on Sakhalin, he rose from an engineer to the head of the Seismology Laboratory and Scientific Deputy Director of the IMGG FEB RAS. A.I.

<p><strong>Abstract.</strong> In Japan, the political system was changed greatly and new Meiji government under Meiji Emperor was born in 1868. Meiji government made great efforts to modernize Japan to hold its independence, hiring many professionals from the western advanced countries, sending many students to the western advanced countries, establishing obligatory education system, and so on.</p><p>It invited French military mission to modernize its army. The mission arrived in Japan in 1872 and stayed until 1880 changing its members. It included engineer officers as follows: Engineer captain Albert Jourdan (1872&ndash;1878), Engineer captain Ernest Vieillard (1873&ndash;1876), Engineer lieutenant captain Lucian Kreitmann (1876-1888) and two other engineer officers succeed until 1880. They worked fundamentally as the teachers of engineering including survey and mapping. Jourdan had additional works as Coast Defense plan and military construction such as Military School.</p><p> Jourdan participated in the Japan Coast Defense Planning Mission headed by French mission chief and ordered by the Army Minister,Yamagata. Coast Defense Plan maps were drawn for Kagosima Bay, Hakodate Bay, Tsuruga Bay, etc. Japanese officers of the General Staff Bureau engaged in making base maps for planning and supported the Mission in the field. The mapping technology would be transferred to the Japanese officers on the job.</p><p>The French Mission members began various military educations in 1872. TIZU SAISIKI (Map Color Rule) was published in 1873, which was translated book by Tomohiro Kosuge (later, the founder and the first director of Japan Land Survey) and others from a French map book brought by Jourdan. Jourdan and Vieillard taught military engineering, based on the textbooks 1855 for French engineer regimental schools, which were translated by T. Kosuge and others and published as KOUHEI SOUTEN (Manual for Military Engineers) including Survey Division in 1873&ndash;1875.</p><p>In 1875, Grand Military Field Exercise was held in Narashinohara near Tokyo, when the field was surveyed at 1/10,000 scale with six plane table teams including T. Kosuge directed by E. Vieillard and a map was compiled and published next year.</p><p>In 1876, the first three textbooks on mapping of the Military School were printed ; SOKUTI KOUHON (Land Survey Textbook), TIRIZUGAKU KOUHON (Topography Textbook) and SOKUTI KANHOU (Rapid Survey Method in the Military School. The former two were Kreitmann’s lecture records and the last one was translated book of a textbook of French Artillery and Engineering Application School Military Field Exercise was held in Narashinohara, when the field was surveyed with plane table method at 1/20,000 scale by the Military School pupils directed by L. Kreitmann. The compiled map was printed next year in the Military School.</p><p>In 1877, Seinan Civil War occurred in Kyushu Islan. Rapid survey maps were drawn by the members of the Survey Division of the Army Ministry. After the war, military field exercise was held in Shimoshidzu, when the field was surveyed with plane table method at 1/20,000 scale by the Military School pupils directed by L. Kreitmann. The compiled map was printed next year in the Military School.</p><p>In 1879, T. Kosuge was nominated to the head of the Survey Division, General Staff Office. He presented his second opinion, “Rapid Survey Plan of the Whole County “ without triangulation which remained as the object of study to the head of the General Staff Office and this plan was accepted.</p><p>In 1880 following the “Rapid Survey Plan”, the rapid survey began with plane table method at 1/20,000 scale in Kanto metropolitan area on a large scale.</p><p>In 1881, according the comparison of the results of the normal triangulation and the graphical triangulation on the plane table, it was concluded that the former should be adopted for the whole country control point survey and that the survey system and organization should be changed.</p><p>In 1889, Army Land Survey was founded by T. Kosuge following the model of Prussian Land Survey, Germany and the first director was T. Kosuge. However, KOUHEI SOUTEN (Manual for Military Engineers) Second Edition, Survey Division was published, translated from the textbook 1883 for the French Engineer Regimental School.</p>

The importance of treatment planning of head and neck malignancies arises from the necessity to achieve homogenous doses to localized target volume surrounded by normal structures, which can produce acute and long-term morbidity. In many radiotherapy departments, a commonly employed strategy is a 3-field technique. Bilateral parallel-opposed fields are matched to anterior lower neck field. In recent years, Intensity Modulated Radiotherapy (IMRT) is used to radiate head and neck tumors. When the target extends to the lower neck regions, abutment of upper IMRT and lower neck fields is required. Field matching represents a technical challenge for the medical physicist, medical engineer, and radiation oncologist to treat multiple fields while avoiding their overlap on the spinal cord. The monoisocentric split field technique has recently become a common technique to achieve matchline homogenous dose while respecting normal tissue tolerance. The aim of this work is to review merits, limitations, and recent approaches to optimize matchline dose in monoisocentric technique in conventional and intensity modulated radiotherapy for head and neck cancers. Although the technique has many advantages, it is subjected to some systematic and random errors due to equipment and patient setup inaccuracies. To decrease the magnitude of matchline inhomogeneities, customized penumbra generator or multileaf collimator have been used. Both methods are viable and represent alternative approaches to the problem of field matching using the asymmetric jaws.

The performance of German airships during the war, and the double crossing of the Atlantic by the airship R34 in 1919, sufficiently impressed the Air Ministry that it embarked on a British airship programme which produced R38 and R80. The Ministry was undoubtedly deterred by the appalling R38 disaster in 1921 but, presumably as a result of Professor Bairstow’s demonstration of the inexcusable inadequacy of the R38 design, they did not abandon their plans. After all R80, to the design of B.N. Wallis, the great engineer who became famous as Sir Barnes Wallis after the 1939-45 war, had been a success. So in 1924 the Air Ministry decided to order two airships, each of five million cubic feet capacity. One, to be called R100, was ordered from the Airship Guarantee Company, a Vickers subsidiary headed by Sir Denniston Burney. It was to be built at Howden. The other, to be called R101, was to be built by the Air Ministry itself, at the Royal Airship Works, Cardington. At the head of the Burney design team was B.N. Wallis. At the head of the Air Ministry design team was V.C. Richmond.

Inter-hospital transport of premature infants is increasingly common, given the centralisation of neonatal intensive care. However, it is known to be associated with anomalously increased morbidity, most notably brain injury, and with increased mortality from multifactorial causes. Surprisingly, there have been relatively few previous studies investigating the levels of mechanical shock and vibration hazard present during this vehicular transport pathway. Using a custom inertial datalogger, and analysis software, we quantify vibration and linear head acceleration. Mounting multiple inertial sensing units on the forehead and torso of neonatal patients and a preterm manikin, and on the chassis of transport incubators over the duration of inter-site transfers, we find that the resonant frequency of the mattress and harness system currently used to secure neonates inside incubators is [Formula: see text]. This couples to vehicle chassis vibration, increasing vibration exposure to the neonate. The vibration exposure per journey (A(8) using the ISO 2631 standard) was at least 20% of the action point value of current European Union regulations over all 12 neonatal transports studied, reaching 70% in two cases. Direct injury risk from linear head acceleration (HIC15) was negligible. Although the overall hazard was similar, vibration isolation differed substantially between sponge and air mattresses, with a manikin. Using a Global Positioning System datalogger alongside inertial sensors, vibration increased with vehicle speed only above 60 km/h. These preliminary findings suggest there is scope to engineer better systems for transferring sick infants, thus potentially improving their outcomes.

✓Guido da Vigevano was an Italian physician and engineer who lived in the 13th and 14th centuries. He was the first scientist who used pictures to illustrate his anatomical descriptions, developing for the first time a close relationship between anatomical studies and artistic drawings. This was further developed in the Renaissance. In his textbook Anathomia are displayed six plates showing for the first time neuroanatomical structures and techniques: dissection of the head by means of trephination, and depictions of the meninges, cerebrum, and spinal cord. On the surface of the brain painting it is possible to recognize a vague patterning of cortical convolutions. Ventricles are also described and shown. This book constituted the first attempt in the history of neuroscience to illustrate an anatomical description with schematic pictures to achieve a better understanding of such complex structures.

For high production of raw coal in steep coal seams, it is crucial to obtain engineer demands by enhancing section height in horizontal caving. However in-situ operations copious methods like pre-blasting was always needed to broken top-coal which was difficult to excavate commodiously and safely. Explosive wave caused by pre-blasting would destroy stress balance around entries, and definitely result in entry disturbed zone (EDZ) being loosen zone. Aimed to determine boundary of EDZ and keep rock mass in both entries steady, combined tests to EDZ of rock masses of head entry of +600 east-side stope of 43# coal seam was done in Wudong Colliery as research background with ground penetrating radar (GPR) and mono-hole ultrasonic wave experiment. It indicated that scope of EDZ here was 2.2-2.3m, which would be prerequisite to optimize supporting scheme in field.

Aluminium coatings that are formed by physical vapour deposition (PVD) on rolled steel products are more resistant to atmospheric and seawater corrosion than zinc coatings. We developed a coating thickness analyzer (CTA) with an X-ray fluorescence (XRF) measuring head, that is integrated into the PVD pilot line. In this study, to conduct measurements of elements with atomic numbers less than 20 while avoiding the problem of registration of light elements, the measuring head was integrated into a process vacuum chamber to maintain a vacuum during the measurements. To validate the proposed tool, cold-rolled steel strips of different grades are used as substrates, and aluminium was deposited on the surface via PVD in thicknesses ranging from 1 to 20 g/m2. The thin-film thickness measurements during a pre-acceptance test were found to have a relative accuracy of less than 5% and a relative precision of less than 1% – 2%. The proposed CTA can be readily integrated in the factory’s automatic process control system and the real-time measurements in operating and calibration modes, and the status of all spectrometric equipment (X-ray tube, detector etc.) can be transmitted to the upper-level computer. Thus, the process engineer can properly control the deposition process.

The article introduces new archival materials into scientific discourse, i. e., the service records of the identified prototypes of official authority figures in <i>The House of the Dead</i> by F. M. Dostoevsky. The archival documents provided an opportunity to fill in the gaps in the biographies of those who held military and medical posts during the writer’s Siberian exile: major Krivtsov, field engineer Gladyshev, head physician Troitsky and resident physician Lovchinsky. It also allowed us to see which of the officials’ traits were depicted in the novel’s characters. A number of events and details were revealed thanks to the memories of the exiled Pole Joseph Boguslavsky. Thus, the prototypical nature of the characters in <i>The House of the Dead</i> was clarified as new facts were revealed and the already known details were revised.

Your classic Jaguar XK 120 stands useless by the roadside. Why? Because you gave priority to the admittedly gorgeous 6 cylinder straight six engine; because you privileged the highest value part. Rubber pipes perish, though, and now thanks to a leak in a cheap hose the head gasket has blown. You are stranded and facing a costly bill. More seriously, your mechanical gaffe is a sign of your misunderstanding of Deleuze. Like Sir William Lyons, he engineers systems where the concept of priority must not be confused with independence, separateness, abstraction or ethical superiority. As a good engineer, Deleuze's constructions are holistic and opposed to abstract hierarchies: if a crucial small, actual part perishes in a particular practical situation where it has a role to play, then it does not matter how much virtual power you have in reserve. Your feet are still in a pool of hot water as you survey the wasted potential of actual motion and ideal expressions, hand made in Coventry.

Modern educational process requires widespread use of various innovative methods aimed at increasing students' interest in mastering academic disciplines, as well as at the integration of Ukrainian educational system into the European educational space. Digital technologies belong undoubtedly to the key innovative technologies allowing to improve significantly the educational process, and to move from monotonous "manual" calculations, that a student has to perform repeatedly one after another, to a conceptual understanding of the main succession of actions to be performed. With this object in view, seven separate computer programs were developed for the course of house water supply and sewerage system design that allow to estimate the maximum second flowrate depending on the number of facilities; to determine the water head loss, nominal diameter and flow velocity for the each section of the cold water pipe to estimate the size and head loss of impeller water meters; to calculate the pump power; to determine the water head loss, nominal diameter and flow velocity for the each section of the hot water pipe; to estimate the total hourly water consumption in the house; to determine the coefficient Ks and to estimate the calculated flow rate in the sewer outlet from the building and in different sections of the sewer in the adjacent to the building territory. The developed computer applications were tested in five groups of the Architecture Faculty of KNUCA in the autumn semester of 2021/2022 academic year when students studied the discipline "Engineer facilities of buildings" The total number of students studying this course was 96 persons. 90 persons of them (93.8%) completed the course project on time. The average score on the course project was 94.5. The results show that the use of computer programs in the educational process increases students' interest in learning the course and motivates them to progress in their studies.

Bispecific antibody and antibody-like molecules are of wide interest as potential therapeutics that can recognize two distinct targets. Among the variety of ways such molecules have been engineered is by creating ""knob"" and ""hole"" heterodimerization sites in the CH3 domains of two antibody heavy chains. The molecules produced in this manner maintain their biological activities while differing very little from the native human IgG sequence. To better understand the knob-into-hole interface, the molecular mechanism of heterodimerization, and to engineer Fc domains that could improve the assembly and purity of bispecific antibodies, we sought crystal structures of heterodimeric and homodimeric aglycosylated Fc fragments bearing ""knob"" and ""hole"" mutations. The structure of the knob-into-hole Fc was determined at 2.64Å. Except for the sites of mutation, the structure is very similar to that of the native human IgG1 Fc, consistent with a hetero-dimer interaction kinetic KD <1 nM. Homodimers of the ""knob"" and ""hole"" mutants were also obtained and their X-ray structures were determined at resolutions of 2.5Å and 2.1Å, respectively. Both kinds of homodimers adopt a head-to-tail quaternary structure and thus do not contain direct knob-knob or hole-hole CH3 interactions. By adding site-directed mutations at F241 and F243 in the CH2 domains, the head-to-tail arrangement was disfavored, leading to increases in both the rate and efficiency of bispecific (heterodimer) assembly.

Undulatory locomotion is an archetypal mode of propulsion for natural swimmers across scales. Undulatory swimmers convert transverse body oscillations into forward velocity by a complex interplay between their flexural movements, morphological features and the fluid environment. Natural evolution has produced a wide range of morphokinematic examples of undulatory swimmers that often serve as inspiration for engineering devices. It is, however, unknown to what extent natural swimmers are optimized for hydrodynamic performance. In this work, we reverse-engineer the morphology and gait for fast and efficient swimmers by coupling an evolution strategy to three-dimensional direct numerical simulations of flows at intermediate Reynolds numbers. The fastest swimmer is slender with a narrow tail fin and performs a sequence of C-starts to maximize its average velocity. The most efficient swimmer combines moderate transverse movements with a voluminous head, tapering into a streamlined profile via a pronounced inflection point. These optimal solutions outperform anguilliform swimming zebrafish in both efficiency and speed. We investigate the transition between morphokinematic solutions in the speed–energy space, laying the foundations for the design of high-performance artificial swimming devices.

Fatal craniovertebral junction (CVJ) injuries were the most common cause of death in high-speed motor sports prior to 2001. Following the death of a mutual friend and race car driver, Patrick Jacquemart (1946–1981), biomechanical engineer Dr. Robert Hubbard, along with race car driver and brother-in-law Jim Downing, developed the concept for the Head and Neck Support (HANS) device to prevent flexion-distraction injuries during high-velocity impact. Biomechanical testing showed that neck shear and loading forces experienced during collisions were 3 times the required amount for a catastrophic injury. Crash sled testing with and without the HANS device elucidated reductions in neck tension, neck compression, head acceleration, and chest acceleration experienced by dummies during high-energy crashes. Simultaneously, motor sports accidents such as Dale Earnhardt Sr.'s fatal crash in 2001 galvanized public opinion in favor of serious safety reform. Analysis of Earnhardt's accident demonstrated that his car's velocity parallel to the barrier was more than 150 miles per hour (mph), with deceleration upon impact of roughly 43 mph in a total of 0.08 seconds. After careful review, several major racing series such as the National Association for Stock Car Auto Racing (NASCAR) and Championship Auto Racing Team (CART) made major changes to ensure the safety of drivers at the turn of the 21st century. Since the rule requiring the HANS device in professional auto racing series was put in place, there has not been a single reported case of a fatal CVJ injury.

In the past two decades, runoff-permeable porous pavement and porous friction courses of pavement systems have been implemented more frequently, first in Europe and subsequently in the United States. Consequently, research and case studies are increasing, with a commensurate increase in the knowledge base for these drainable pavement matrices and systems. The main distinguishing parameter of these porous matrices is the hydraulic conductivity (k), as compared with traditional impervious pavements. Equipment and standards for measuring k vary widely. This variability includes laboratory and field permeameters, constant-head and falling-head permeameters, and methods based on differing equipment and differing protocols. In many cases, such variability generates results that are either difficult to compare or not comparable. As a result, the value of k that is generated from different methods and different equipment is uncertain. The disparate methods and measurement of k as a parameter challenge the researcher and the practitioner. During the development and specifying phase, the researcher and the designer require a representative value of k to ensure proper predictive models and design. During and after construction, the engineer and the practitioner require k for quality control. This paper illustrates and summarizes the available methods for measuring the k of pavement porous mixes. Some case studies are examined to verify the differences between methods and equipment used for determination of k. The European Standard UNI EN 12697-19 is examined through an experimental study. Theoretical and practical results help explain the measurement of k for pavements as a primary parameter of porous runoff-permeable mixes.

The article introduces the life of not well-known in Latvia Latvian born Lithuanian Karolis Reisonas (in Latvian: Kārlis Reisons; 1894–1981) and his professional activities in Šiauliai city, as well as highlights the main features of the architect’s creative work and the importance of his work in the history of Lithuanian architecture. K. Reisonas was one of the most prominent creators of modern architecture of the 20th century during interwar period in Lithuania. He is the author and co-author of representative buildings in the cities of Lithuania, as well as in Riga and Adelaide (Australia). K. Reisonas graduated from Riga Real School (1913) and St. Petersburg Institute of Civil Engineers (1920). He has worked as the Engineer of the Šiauliai city and Head of the Construction Department of the Municipality (1922–1930), the Director of the Tenth1 Courses of Šiauliai Construction (1925), later – the Director of the Šiauliai Vocational School (1926), and an Advisor of Lithuania Chamber of Agriculture (1927–1928). Fourteen building to his design in Kaunas and Šiauliai cities are included in the list of cultural values of Lithuania. K. Reisonas’ early projects are characterized by historicism, eclectic elements, of «brick style». Later projects have the features of aesthetic rationalism, functionalism, and adaptation to urban and cultural-historical context. After the Second World War, he and his family immigrated to Germany, later Adelaide in Australia, where he participated in the life of the Adelaide Lithuanian community.

Stewart Crichton Miller, a mechanical engineer of great distinction, was the former Director of Engineering and Technology for Rolls-Royce plc, where he worked for over 40 years. Stewart was a foremost contributor to several of the company's most important development projects, chief among them being the RB211-535 engine project, which is used on Boeing 757 aircraft. Stewart was born on 2 July 1934 to William and Grace Miller in Kirkcaldy, Fife, where he spent his childhood. His primary school education at Kirkcaldy Fife High Primary School started on 4 September 1939, the day after war was declared. A contemporary, with whom he was a close friend during school years, is Archie Howie (F.R.S. 1978), a distinguished physicist and former Head of the Cavendish Laboratory, Cambridge. Professor Howie recalls that he and Stewart vied with each other for school prizes, etc., with Stewart emerging as the Dux of the primary school. On leaving primary school, Stewart attended Kirkcaldy High School from 1945 to 1951. It was there that he received the Scottish Higher Learning Certificate in 1950 and an award in the Edinburgh University Bursary Competition. He continued his education at the University of Edinburgh from 1951 to 1954, enrolling as an engineering degree candidate. His choice of engineering as a career was considered unusual by others for someone of his high academic abilities. However, this doubt only increased his determination. His research emphasis while studying was on mechanical vibration, which served as useful background for his later work at Rolls-Royce on turbo-machinery. He graduated in 1954 from Edinburgh with a BSc (firstclass honours) in mechanical engineering. After leaving university, Stewart spent two years completing a graduate apprenticeship with Rolls-Royce that marked the beginning of his extensive career. Spending his first year gaining workshop experience and his second in all the major technical offices, Stewart subsequently qualified to receive the status of Chartered Engineer.

The article sets the task of determining the area of effective application of solid and through columns. The parametric optimization method is used as a research method. The accepted optimality criterion includes the cost of steel, the cost of column manufacturing and the cost of applying corrosion protection. The main parameters affecting the intensity of metal and cost of the column are the load, the calculated length and the radius of inertia of the section. In the study, the type of cross-section of the column is adopted unchanged, in the form of an I-beam (is a limitation); the load and length of the column are taken as variable parameters. The design scheme of the structure is a centrally compressed column with hinged fastening of the base and the head. According to the regulatory conditions of stability and ultimate flexibility, the required cross-sectional area for each value of the variable parameter is determined. Charts with selected areas of optimal application are compiled; it helps the design engineer to choose between a solid or through section of the column, depending on its actual load and length.

This article discusses plastic gears that are ideally suited to the power transmission demands of a rotary sprinkler. They operate in wet conditions without oil or grease. Despite many advances in plastic gear technology, users of metal gears have not begun trading in all their current cogs for plastic versions. In order to reduce the chance of plastic gears jumping teeth in its sprinkler head, Hunter Irrigation molded an asymmetric tooth on the pinion that drives the ring. According to an expert, mold enough of them and plastic gears eventually compete with, then surpass, the economics of metal gears. Closter, New Jersey-based Intech Corp. has developed a method of cutting gears from plastic to take advantage of the material’s strengths. LNP Engineering Plastics Inc. of Exton, Pennsylvania, makes pellets for manufacturers of plastic parts. Ed Williams, an LNP application development engineer and chairman of the AGMA Plastic Gearing Committee, said that despite limited engineering data for plastic gears, designers can find other ways to determine how well certain materials will suit an application. Compiled wear data exists for plastic based on thrust washer wear tests, for instance.

The application of 3D printing and microcontrollers allows users to rapidly engineer novel hardware solutions useful in a laboratory environment. 3D printing is transformative as it enables the rapid fabrication of adapters, housings, jigs, and small structural elements. Microcontrollers allow for the creation of simple, inexpensive machines that receive input from one or more sensors to trigger a mechanical or electrical output. Bringing these technologies together, we have developed custom solutions that improve capabilities and reduce costs, errors, and human intervention. In this article, we describe three devices: JetLid, TipWaster, and Remote Monitoring Device (REMIND). JetLid employs a microcontroller and presence sensor to trigger a high-speed fan that reliably de-lids microtiter plates on a high-throughput screening system. TipWaster uses a presence sensor to activate an active tip waste chute when tips are ejected from a pipetting head. REMIND is a wireless, networked lab monitoring device. In its current implementation, it monitors the liquid level of waste collection vessels or bulk liquid reagent containers. The modularity of this device makes adaptation to other sensors (temperature, humidity, light/darkness, movement, etc.) relatively simple. These three devices illustrate how 3D printing and microcontrollers have enabled the process of rapidly turning ideas into useful devices.

In the context of studies about space and school architecture, this article analyses the visual construction of the Fernando Gomes Elementary School, which was located in downtown Porto Alegre/RS, Brazil between 1913 and 1935. Designed by the engineer Afonso Hébert, head of the Department of Public Works in the State of Rio Grande do Sul/RS, the building was completed in 1922. In addition to functional elements, i.e., a large number of classrooms that would serve to increase the access of children to primary school, its monumental proportions incorporated a series of symbolic elements aligned with the ideals of the First Brazilian Republic (1889–1930). The documentary analysis was performed on the archives of the Directorship of Public Education and the Directorship of Public Works of Rio Grande do Sul, as well as various iconographic sources, capital improvement plans and periodicals of the time. The construction of the school inaugurated a new conception of the space and architecture of public elementary schools in the State, as the visible improvement and sanitation of the cities were considered of great importance in the period. The construction of school buildings was also one of the greatest advertising tools of the new Republican political regime.

The pump requirement is required to meet the specified performance parameters means the required pressure (head) and flow, using less power. For water pump applications, periodic maintenance is required to check worn parts such as wear ring, shaft sleeves. In such a case the direct separation case pumps are reliable. If a given work point can meet the range of pumps of the available separate cases, it is necessary to develop a new pump and the upgraded pump should be more efficient with the considered power problems. With the help of computational fluid dynamics, the complex internal flow of the pump in the case of equilibrium separation can be accurately predicted, thus facilitating the construction of the pump. Simulation provides the most complete performance testing and important diagnostic details that help the engineer quickly and increase composition. As a result, the company is able to quickly create new designs such as a fully patented water pump with a patent. Pressure suction can be problematic during operation and operation of centrifugal pumps. Such pressure stimulants are traditionally investigated but quantitative analysis techniques allow these effects to be tested. Numerical analysis is done with a multi-reference framework to predict the flow field within the entire pipeline and impeller.

AbstractIn 1926 Zhou Xicheng, Governor of Guizhou, China, obtained a new car from an American Motor Company, the first car ever to find its way to this remote Chinese province. Road construction in Guizhou was well underway when the American engineer O. J. Todd, a member of the China International Famine Relief Committee, was invited that year to assist in its continued development. Governor Zhou had his own methods for the speedy and effective building of roads and recruited local people, the army, and even large teams of school children to assist in construction. It is likely that his work methods had taken their inspiration from Sun Yat-sen's plans as outlined in his book The International Development of China of 1920; plans that Sun Yat-sen further promoted in the writing of a letter to Henry Ford in which he requested the industrialist's assistance in the improvement of the motor industry in China. In 1928, in an effort to commemorate his own role in China's road construction projects, Zhou Xicheng had a coin struck. Instead of showing an image of his own head or that of another luminary such as Sun Yat-sen or Yuan Shikai - as had been common with coins of the first decades of the twentieth-century - this one yuan silver coin shows an image of his beloved motor car.

The leadership of women at the highest political level remains an ongoingcontroversial issue for Muslims.1 And yet women have led both medievaland modern Muslim societies – Pakistan, Indonesia, and Bangladesh –thereby rendering this debate, in practice, moot. But quite a few Muslimmen consider this reality as an abomination and perversion.In his Al-Aḥkām al-Sulṭānīyah wa al-Wilāyāt al-Dīnīyah, al-Mawardi (d.1058) discusses the imamate in the sense of the caliphate (khilāfah: Islamicleadership) and lists its conditions.2 Rather surprisingly, gender is not one ofthem. However, Asghar Ali Engineer writes that “al-Mawardi maintained thata woman cannot be made head of state.”3 Although the gender clause is notfound in Al-Aḥkām al-Sulṭānīyah written by the Hanbali Abu Ya‘la al-Farra’(d. 1113) and other early works, later scholars categorically include it.The Shafi‘i Ahmad ibn Ali al-Qalqashandi (d. 1418) cites masculinity asthe first of the fourteen conditions of eligibility. He bases his decision on thehadith reported by al-Bukhari and narrated by the Companion Abu Bakra.This scholar explains how a leader has to mingle with other men to discussstate affairs, an act that Islam prohibits for women. He adds that “because awoman is incomplete in her own right, as she does not even control her marriage,she cannot be made a leader over others.”4 I contend that his and similarremarks are seriously influenced by cultural circumstances, ones that are nottruly reflective of Islam.
