Rapidly progressive ACTH-dependent Cushing’s disease masquerading as ectopic ACTH-producing Cushing’s syndrome: illustrative case
Authors: Yu Siyuan , Karsy Michael , Miller Jeffrey , Beldick Stephanie R. , Curtis Mark T. , Rosen Marc , Evans James J.
Published: July 2021

BACKGROUND

Cushing’s disease (CD) remains a challenging condition to diagnose and treat. This case study highlights the challenges of diagnosing CD when faced with discrepant clinical, biochemical, and radiological findings.

OBSERVATIONS

A 62-year-old man presented with rapid evolution of symptoms, including depression, fatigue, and extreme muscle atrophy, which resulted in the patient being a wheelchair user over the course of a few months. His rapid clinical course in conjunction with hypercortisolemia in the setting of a pituitary macroadenoma involving the cavernous sinus, two large pulmonary nodules, and urine-free cortisol levels in the thousands suggested an aggressive ectopic adrenocorticotropic hormone (ACTH) source. After extensive testing ruled out CD from an ectopic source and because of the patient’s abrupt clinical deterioration, the authors concluded that the source was likely an aggressive pituitary adenoma. Therefore, the authors performed an endonasal transsphenoidal approach for resection of the pituitary adenoma involving the cavernous sinus, and the patient was scheduled for radiosurgery to control tumor progression.

LESSONS

Although extremely high levels of cortisol and ACTH are associated with ectopic Cushing’s syndrome, they may also indicate an aggressive form of CD. Suspicion should be maintained for hypercortisolemia from a pituitary source even when faced with discrepant information that may suggest an ectopic source.
Symptomatic contralateral osteophyte fracture with migration causing lumbar plexopathy during oblique lumbar interbody fusion: illustrative case
Authors: Pennicooke Brenton , Guinn Jeremy , Chou Dean
Published: July 2021

BACKGROUND

While performing lateral lumbar interbody fusion surgery, one of the surgical goals is to release the contralateral side with a Cobb elevator, allowing distraction of the interbody space. Many times, there are large osteophytes on the contralateral side, and the osteophytes can be split open with the Cobb or blunt instrument. It is extremely rare for the actual osteophyte to break off from the vertebral body into the contralateral psoas muscle and lumbar plexus.

OBSERVATIONS

The authors report a case of symptomatic lumbar plexopathy caused by an osteophyte fracture after an oblique lumbar interbody fusion requiring a right-sided anterior approach to excise the bony fragment. They illustrate the case with imaging that the radiologist did not comment on, and they also show a video of the surgical excision of the osteophyte through a right-sided anterior lumbar retroperitoneal approach. The authors also show how the patient had spontaneous right-sided electromyography (EMG) firing before excision of the osteophyte and how the EMG firing resolved after excision.

LESSONS

Although the literature is plentiful with regard to ipsilateral approach–related complications, the authors discuss the literature with regard to contralateral complications after minimally invasive lateral lumbar interbody fusion.
Awake craniotomy for glioblastoma in COVID-19–positive patients and delivering the standard of care: illustrative case
Authors: Alvarez Reinier , Kotecha Rupesh , McDermott Michael W. , Siomin Vitaly
Published: July 2021

BACKGROUND

Providing the standard of care to patients with glioblastoma (GBM) during the novel coronavirus of 2019 (COVID-19) pandemic is a challenge, particularly if a patient tests positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Further difficulties occur in eloquent cortex tumors because awake speech mapping can theoretically aerosolize viral particles and expose staff. Moreover, microscopic neurosurgery has become difficult because the use of airborne-level personal protective equipment (PPE) crowds the space between the surgeon and the eyepiece. However, delivering substandard care will inevitably lead to disease progression and poor outcomes.

OBSERVATIONS

A 60-year-old man with a left insular and frontal operculum GBM was found to be COVID-19 positive. Treatment was postponed pending a negative SARS-CoV-2 result, but in the interim, he developed intratumoral hemorrhage with progressive expressive aphasia. Because the tumor was causing dominant hemisphere language symptomatology, an awake craniotomy was the recommended surgical approach. With the use of airborne-level PPE and a surgical drape to protect the surgeon from the direction of potential aerosolization, near-total gross resection was achieved.

LESSONS

Delaying the treatment of patients with GBM who test positive for COVID-19 will lead to further neurological deterioration. Optimal and timely treatment such as awake speech mapping for COVID-19–positive patients with GBM can be provided safely.
Papillary glioneuronal tumor growing slowly for 26 years: illustrative case
Authors: Shinno Kazuma , Arakawa Yoshiki , Minamiguchi Sachiko , Terada Yukinori , Tanji Masahiro , Mineharu Yohei , Kikuchi Takayuki , Haga Hironori , Miyamoto Susumu
Published: July 2021

BACKGROUND

Papillary glioneuronal tumors (PGNTs) are classified as a type of World Health Organization grade I mixed neuronal-glial tumor. Most PGNTs involve cystic formations with mural nodules and solid components in the cerebral hemispheres, and PGNTs occur mainly in young adults. The long-term prognosis of PGNTs remains unclear.

OBSERVATIONS

A 38-year-old male had been diagnosed with an arachnoid cyst associated with epilepsy in a local hospital. The initial magnetic resonance imaging (MRI) study showed the tumor as a heterogeneously enhanced nodule in the left postcentral gyrus. Subsequent MRI studies showed slow growth of the tumor for 26 years. He underwent gross total resection to control his epilepsy. The histopathological findings revealed pseudopapillary structures involving hyalinized blood vessels with a single or pseudostratified layer of cuboidal glial cells with round nuclei and scant cytoplasm. At the periphery of the lesion, Rosenthal fibers and acidophilic granule bodies were observed in the gliotic brain tissue. Immunohistochemically, some interpapillary cells were positive for NeuN. On the basis of these findings, the tumor was diagnosed as a PGNT.

LESSONS

This PGNT showed slow growth for 26 years. When recognizing a slowly growing tumor in the cerebral hemispheres of relatively young people that is associated with epileptic seizures, PGNT should be considered as a differential diagnosis.
Robot-assisted revision of sacroiliac joint fusion using a triangular titanium implant in an S2-alar-iliac trajectory: illustrative case
Authors: Triano Matthew , Fayed Islam , Sandhu Faheem A.
Published: July 2021

BACKGROUND

Sacroiliac joint (SIJ) dysfunction can lead to significant pain and disability, greatly impairing quality of life. Arthrodesis may take up to 1 year to occur, after which revision can be considered. There is a need for highly accurate and reproducible techniques for revision that allow for purchase through undisturbed bone to prevent prolonged pain and disability. Moreover, a minimally invasive technique for revision would be favorable for recovery, particularly in elderly patients.

OBSERVATIONS

An 84-year-old man with a prior history of lumbar fusion presented with severe buttock pain limiting ambulation and sitting because of the failure of arthrodesis after SIJ fusion 1 year earlier. He underwent revision using a triangular titanium implant (TTI) in an S2-alar-iliac (S2-AI) trajectory under robotic guidance, which is a novel technique not yet described in the literature. The patient’s pain largely resolved, he was able to ambulate independently, and his quality of life improved tremendously. There were no complications of surgery.

LESSONS

Placement of a TTI using an S2-AI trajectory is a safe and effective method for revision that can be considered for elderly patients. Robot-assisted navigation can be used to facilitate an accurate and reproducible approach using a minimally invasive approach.
THE SIMULACRUM NARRATIVE OF HISTORY INTERPRETATION IN POST-TOTALITARIAN CULTURE
Authors: Humeniuk Tetiana , Lehenkyi Yurii
Published: July 2021

The purpose of the article is to highlight the features of contemporary national culture as a special artistic meaning of the Gesamtkunstwerk, which is formed by a reflection of a predominantly historical pattern. The research methodology consists of a set of scientific methods of general and special nature. Methods of analysis and synthesis, as well as historical, cultural and systemic approaches, were used to reveal the essence of virtual reality of super narratives in the information space, which are the impetus for the formation of ethical, aesthetic and artistic consensus. The relevance of the research is determined by the need to study the postmodern paradigm, which gives the rise to the new discourses that replace the narratives of the communist era in the interpretation of the history of the posttotalitarian space. The scientific novelty of the study is that it shows post-Soviet culture as an inertial phase of post-totalitarianism, which has an image simulative tottalogy of reality. Conclusions. The article demonstrated that the artistic meaning of the Gesamtkunstwerk of the post-Soviet space is a desirable reality, but it has stopped at the level of the fairy-tale narrative, which is formed by a reflection of a predominantly historical pattern. The time and space of culture in the dimension of the simulacrum world appear as another kind of aesthetics virtus. It has been noted that the cultural reality of post-totalitarianism is at a stage when it is necessary to realise that the invented reality of the fairy-tale type is not art. So, the hybridity of creative efforts, post-coloniality, hypercriticism as a way of being, vital energy represent a set of motives that adds little to the understanding of the situation of postmodern creativity in Ukraine. Conversely, national slogans indicate the need for a national identity, because time is waiting for the manifestation of creative initiatives of artistic synthesis.
EVOLUTION OF THE CULTURAL MODEL OF THE UKRAINE IMAGE IN THE INTERNATIONAL INFORMATION SPACE
Authors: Koshelieva Oksana
Published: July 2021

The purpose of the article is to determine the sociocultural determinants of the transformation of Ukraine foreign image under the influence of domestic and foreign political events and the state of its coverage in the information space; to ascertain the evolution of the cultural model of the image of Ukraine in the international information space. The research methodology consists in the use of interdisciplinary methods and approaches to identify information and communication technologies aimed at the formation of the international image of Ukraine; the principle of historicism allowed determining the stages of changes in the information space and the transformation of the geopolitical situation around Ukraine; the structural and comparative methods were used to determine the international media positions on Ukraine, their influence on the formation of its image. The scientific novelty of the research is in the presentation of the Ukraine image as an expression of the mentality of a particular cultural and historical community, an indicator of cultural meanings, unique design, mechanism of realisation of a national culture through a set of sign objectivations formed within a particular cultural and historical space and consolidated in the mental representations of individuals. Conclusions. It is proved that the negative image of Ukraine created by Western media affected the development of its tourism sector, the promotion of national cultural heritage and the investment climate significantly. The modern image of Ukraine is undergoing reformatting; there are significant cultural, political, and economic changes. The cultural model of the positive image of Ukraine in the international information space is determined by a properly structured state cultural policy and the effective use of modern image-making tools that can set it on the path of cultural, political and economic stabilisation.
IMPACT OF CURRENT TOURISM TRENDS ON THE FORMATION OF LEISURE CULTURE: UKRAINIAN CONTEXT
Authors: Ustymenko Lesia
Published: July 2021

The purpose of the article is to analyse the impact of current tourism trends on the formation of leisure culture. The research methodology consists of the analysis of the primary statistical and scientific sources on the impact of tourism trends on the shape of leisure culture, interdisciplinary synthesis of the main forms of actualisation of tourism trends on the localisation of tourist flows, methods of deduction and induction, as well as content analysis. Scientific novelty. The article identifies current tourism trends of our time, which will significantly shape leisure overculture. The author grounds and introduces into scientific use of the theory of cultural studies and tourism studies the concepts of “tourism trend” and “leisure culture”. Conclusions. Based on the analysis of statistical materials of the World Tourism Organization (UNWTO), data from United Nations experts, the history of tourism development vectors in the context of a pandemic is summarised. The article describes and analyses current tourism trends that will impact the formation of leisure culture in the years to come. In particular, the development of domestic tourism under the condition of improving its service; the use of social networks for marketing and marketing of a tourism product; the development of internet technology, 24-7 blogging support; the development of virtual tourism, which is provided by virtual (VR) and augmented (AR) reality; 24-7 customer support chatbots (chatbots); robot staff in the system of essential tourism services (transport, accommodation and leisure services). Thus, if there is an improvement of domestic service, the current tourism trends will create an environment where we can expect Ukrainian tourism to be a significant segment of leisure culture.
LIGHTING IN THE INTERIOR DESIGN OF RELIGIOUS BUILDINGS IN GALICIA (THE SECOND HALF OF THE 19th AND THE FIRST THIRD OF THE 20th CENTURIES)
Authors: Odrekhivskyi Roman
Published: July 2021

The purpose of the article is to analyse the typology, design features and carved decor of the wooden lamps in the interiors of the religious buildings in Galicia. The research methodology is based on the general principles of scientific work: consistency, authenticity, historicism, logic. The author of the article applies a comparative and typological method to analyse the design features of the lamps. And the methods of hermeneutics and semiotics were used to analyse ornamental and compositional systems of decoration. The scientific novelty of the work is the introduction of the unknown artefacts of church art into the scientific circulation. The author collected these data himself during his scientific expeditions to museums or directly in churches — both in Ukraine and abroad. Conclusions. The study of the design features and decor of the analysed lamps has shown that table lamps, as a rule, are smaller than candelabras (stavnyk), although sometimes according to the principle of composition, they are the same as candelabras, as, for example, the candelabra from the Kryvorivnia Church of the Nativity of the Blessed Virgin Mary. The study has confirmed that the lamps harmoniously fit into the design of the church interior, complementing the ensemble. For example, in the church in the village of Duliby or Pozdiach. In fact, the design ensembles of these religious sites are made in the same style. The author of the article provides an analysis of the image design solution and the nature of the decor of specific samples of the lamps, and argues that the development of the lamp art (as well as other elements of church equipment) occurs in two directions: imitation of historical styles in line with eclectic versions and the use of ornamental and compositional structures of traditional folk art. The features of a successful combination of these trends in the image solution of the spider chandelier from Galicia, which is kept in the collection-exposition of the National Museum in Lviv, have been demonstrated. The study has shown the original use of Hutsul folk carving traditions in the decoration of the spider chandelier from the Church of St. George in the village of Duliby, made by the famous master Vasyl Turchyniak: he used traditional geometric ornaments with ancient symbols. The significance of the © Roman Odrekhivskyi, 2021 The article was received by the editorial office: 11.08.2020 study lies in the possibility of using the processed material in the restoration of the old and construction of the new churches.

Authors: Dudka M. I. , Yakunin O. P. , Pustovyi S. I.
Published: July 2021

The influence of foliar top dressings on the background of mineral fertilizers N30P30K30 and N60P45K45 on the leaf surface area, grain yielding capacity and economic indices for the griowing of maize hybrids after sunflower was studied. It is found that against the background of fertilizer N60P45K45 compared to N30P30K30 leaf area of one plant was greater by 7.0 %. Under the influence of foliar top dressing, this indicator increased by 7.7–25.6 %. The middle-early ripening hybrid had advantage in terms of leaf surface area. The yielding capacity of maize on the background of mineral fertilizers N30P30K30 was 4.76 t/ha, on the background of N60P45K45 – 5.20 t/ha. In the case of foliar top dressing with Carbamide at a dose of 10 kg/ha, grain yielding capacity increased compared to the control (without dressing) by 0.20 t/ha, at the dose of 20 kg/ha – by 0.24 t/ha. The addition of Zinc chelate, 1.5 l/ha, to 10 kg/ha of Carbamide, provided an increase in grain yielding capacity compared to the control by 0.30 t/ha, and up to 20 kg/ha of with Carbamide of Quantum-corn, 3.0 l/ha – by 0.34 t/ha. In the case of two foliar top dressings: with Carbamide and Zinc chelate in the phase of 5–6 leaves, Carbamide and the preparation of Quantum-corn in the phase of 8–9 leaves, the grain yielding capacity was higher than in the control by 0.41 t/ha. According to this indicator, the middle-early ripening hybrid DB Khotyn exceeded the early-ripening hybrid DN Pyvykha by 0.50 t/ha. The cost figures of 1 ton of grain was lower for growing middle-early hybrid with a single spraying of crops with Сarbamide or Carbamide with the addition of microelements on the background of fertilizer N30P30K30 (2159–2259 UAH) and slightly higher (2212–2301 UAH) – on the background of N60P45K45 medium-early hybrid on the background of N60P45K45. The conditional net income with a single spraying of Carbamide (10214–10327 UAH/ha) and slightly less (10095–10164 UAH/ha) – Carbamide with the addition of Zinc chelate or Quantum corn. The level of profitability was highest (89.9 %) at growing of medium-early hybrid on the background of N30P30K30 and spraying crops with Carbamide, 10 kg/ha (5 % solution). Key words: maize, fertilizer, foliar top dressing, hybrids, yielding capacity, economic efficiency.

Published: July 2021

The study of the gene pool of gray Ukrainian cattle on the basis of the State Enterprise “Polivanovka” was carried out in 2018–2020. They relied on retrospective and modern analysis of the population, using genetic, immunogenetic, breeding, zootechnical, statistical and biometric methods. The animals of this herd belong to two lines: Petushok 191U (62 %) and Shamrin XU-41 (38 %) and 20 families. They have a sturdy, dense and rough type of constitution. Average somatometric indicators correspond to the standard. The breed has good slaughter performance and beef properties. Slaughter yield in bulls reaches 58–59 %, fat – 2.5–3 %, protein: fat ratio – 1: 1.5, pulp in the carcass – 72–73 %, bones – 16–17 %, meat index – 4, 4–4.5. Animals with a high coefficient of inheritance pass on to their descendants specific breed characteristics (color, shape of horns, physique, acclimatization to various natural zones, adaptation to feeding conditions, increased resistance, small fruit size, long growth, stress resistance). The use of modern techniques made it possible to test erythrocyte antigens, serum proteins, isozyme erythrocytes and tissues, as well as polymorphism, the length of restriction DNA fragments. Of the 49 antigens of blood groups, 48 were found. There was a high frequency of them (45–92 %) A, G3, C1, C2, R2, W, X1, X2, E, F, Y, J, H1, Z and much lower ( 2–10 %) P1, P2, B1, J2, P1, R, C1, L, H2. Over the past 30 years, the number of alleles of the most informational system B has decreased from 41 to 14, among them breed-specific B, B2, G3, J1, Q, T1, G2, K, V, E, O. The narrowing of the allelic pool to this level indicates that the breed is on the verge of extinction. Analysis of biochemical markers of blood serum proteins albumin and post-albumin was found in three phenotypes AA, BB, and AB, post-transformation – also in three phenotypes FF, FS, and SS. In terms of hemoglobin, all studied animals of the herd are of type A. Restriction analysis of mitochondrial DNA revealed polymorphism only for endonuclease Eco 471. Modern selection and genetic methods are able to maintain and preserve the specific properties of the breed, its structure, and genetic variability. Their use in combination with technological methods helps to prevent the disappearance of livestock and provide it with a worthy place in the world heritage of genetic resources. Our proposals are summarized in the "Concept of purposeful conservation of gray Ukrainian cattle and their use in the further breed-forming process." Key words: cattle, gray Ukrainian breed, condition, direction of use, offers.

The Effect of Kindergarten Teacher Coaching on Handicraft Skills to Improve Implemented Technical Products: An Approach to Tackle Unemployment
Authors: Ahmed Hanan Abdalnabi Al Saied
Published: July 2021

ABSTRACT Handcrafts contribute significantly to sustainable socioeconomic development and poverty alleviation in local communities, by creating substantial employment and income opportunities for people. The aim was to investigate the effect of kindergarten teacher coaching on handicraft skills to improve implemented technical products. Participants were 20 unemployed female kindergarten teachers. They aged from 22-29 years old (M= 25 years, SD= 3.52). This study utilised a Quasi-Experimental (Pre-Test and Post-Test), one group design. Data were collected from children during the academic year 2019-2020. Data were analysed using t-test, ANOVA test, and Eta Squared. The group participated in 10 workshops, in which they were trained in doing textile design printing, forming ceramic pastes and synthesis with environmental materials. The results show there is a significant difference between the group’s performance before and after the program. This confirms that the handicrafts could positively impact kindergarten teachers’ textile design printing, forming ceramic pastes and synthesis with environmental materials. At the end of the study, recommendations were provided.
Determination of the optimal composition of mixed fuel based on environmental indicators of diesel engine
Authors: Plotnikov S. A , Gnevashev P. V
Published: July 2021

Alternative motor fuel is a mixture of various hydrocarbons and their compounds. Motor fuel is based on naphthenic, paraffinic and aromatic hydrocarbons. The performance characteristics of the fuel depend on its composition. When developing methods for monitoring the characteristics of fuels, the main problem is their multicomponent nature, since each component contributes to the operational characteristics. The operational characteristics are: cetane number, sulfur content, water-soluble acids and alkalis, lower heat of combustion and some others. To determine them, the combustion of diesel fuel (DF) and the subsequent analysis of the combustion products are carried out. The disadvantage of the existing method is the fact that it is impossible to quickly control the fuel at the place of operation, at a tank farm, a gas station, a process pipe or a vehicle fuel tank. When designing analyzers and measuring instruments the correlation dependences, which link the value of the operational property of the fuel with its physicochemical characteristics, are used. Taking into account the use of various types of alternative fuels (AT) with a wide range of their operational properties, the problem of a quick and accurate preliminary assessment of these properties arises. Along with diesel fuel, it is proposed to use similar physicochemical methods to assess the flammability of alternative fuels.
Threshing and separating device
Authors: Sobolev M. O , Tarasenko B. F , Mechkalo L. F , Voynash S. A , Sokolova V. A
Published: July 2021

The article presents a brief analysis of the technology of harvesting grain crops and technical means, from which it follows that one-section threshing-separating decks structurally look as follows. The “sockets” for their installation in the combine are fixed on the side cheeks, which, in turn, are rigidly connected to the transverse strips, installed between them at a uniform interval along the entire length of the deck, and the transverse strips with their inner side are located on a cylindrical surface with a certain drum wrap angle. At the same time, to increase the rigidity of the transverse strips and the entire deck as a whole, below the surface of the bar tier, the transverse strips are interconnected by rectangular ribs curved along a concentric circle of a larger radius than the radius of the working surface of the separating grid. All decks are installed on the combine with respect to the outer diameter of the drum beaters, not along a concentric circle, but with an offset. Therefore, the principal disadvantages of single-drum single-section decks are the high levels of under-threshing, loss of free grain in the coarse heap through straw walkers, and especially crushing. In this connection, there is a need for its improvement, as well as the need to modernize the threshing-separating device with an improvement in the operation of the air-sieve cleaning. On the basis of prospecting studies, a single-section threshing deck protected by the RF patent was proposed. The deck consists of at least three zones. In the first zone of threshing and separation the separating grid is made two-tier, with a variable distance between the tiers by means of a variant installation under the main tier of removable bars of the grid, located on the transverse slats with a step t larger on radii than those of the main tier, passing in the middle of the step bars of the main upper tier with intervals from 0.75 to 1.25t. In the second zone of separation and threshing the separating grid with a length of 5 to 12 intervals between the transverse strips is single-tier, but the step between the grid bars located on the continuation of the tier of the first zone on the transverse strips of the zone is at least 1.5t of the step. In the third zone of final threshing and separation with a length of no more than 6 intervals between the transverse slats, a single-tier grating is a continuation of the upper tier of the first zone with a bar pitch from 0.5 to 1.5t of the first zone pitch. This solution has practical significance and perspective for implementation by installing them on self-propelled grain harvesters.
The Genesis of the Self
Authors: Mead George Herbert
Published: July 2021

THE SELF THAT is central to all so-called mental experience has appeared only in the social conduct of human vertebrates. It is just because the individual finds himself taking the attitudes of the others who are involved in his conduct that he becomes an object for himself. It is only by taking the rôles of others that we have been able to come back to ourselves. […]

It is interesting to note that in the development of the individual child, there are two stages which present the two essential steps in attaining self-consciousness. The first stage is that of play, and the second that of the game, where these two are distinguished from each other. In play in this sense, the child is continually acting as a parent, a teacher, a preacher, a grocery man, a policeman, a pirate, or an Indian. It is the period of childish existence which Wordsworth has described as that of “endless imitation.” It is the period of Froebel’s kindergarten plays. In it, as Froebel recognized, the child is acquiring the rôles of those who belong to his society. This takes place because the child is continually exciting in himself the responses to his own social acts. In his infant dependence upon the responses of others to his own social stimuli, he is peculiarly sensitive to this relation. Having in his own nature the beginning of the parental response, he calls it out by his own appeals. The doll is the universal type of this, but before he plays with a doll, he responds in tone of voice and in attitude as his parents respond to his own cries and chortles. [...] That is, one calls or tends to call out in himself the same response that he calls out in the other.
The I in the Internet
Authors: Tolentino Jia
Published: July 2021

IN THE BEGINNING the internet seemed good. “I was in love with the internet the first time I used it at my dad’s office and thought it was the ULTIMATE COOL,” I wrote, when I was ten, on an An­gelfire subpage titled “The Story of How Jia Got Her Web Addic­tion.” In a text box superimposed on a hideous violet background, I continued:

But that was in third grade and all I was doing was going to Beanie Baby sites. Having an old, icky bicky computer at home, we didn’t have the Internet. Even AOL seemed like a far-off dream. Then we got a new top-o’-the-line computer in spring break ’99, and of course it came with all that demo stuff. So I finally had AOL and I was completely amazed at the marvel of having a profile and chatting and IMS!!
The Self
Authors: James William
Published: July 2021

The Me and the I.—Whatever I may be thinking of, I am always at the same time more or less aware of myself, of my personal existence. At the same time it is I who am aware; so that the total self of me, being as it were duplex, partly known and partly knower, partly object and partly subject, must have two aspects discriminated in it, of which for shortness we may call one the Me and the other the I. I call these “discriminated aspects,” and not separate things, because the identity of I with me, even in the very act of their discrimination, is perhaps the most ineradicable dictum of common-sense, and must not be undermined by our terminology here at the outset, whatever we may come to think of its validity at our inquiry’s end.

I shall therefore treat successively of (A) the self as known, or the me, the ‘empirical ego’ as it is sometimes called; and of (B) the self as knower, or the I, the ‘pure ego’ of certain authors.

Authors: Priyotomo Gadang
Published: July 2021

Masalah korosi merupakan salah satu pertimbangan biaya pemeliharaan dalam proses produksi industri minyak dan gas bumi, petrokimia dan geothermal. Salah satu metode mitigasi korosi adalah proses pelapisan polimer atau cat. Walaupun struktur di lapis oleh cat, proses korosi terjadi karena preparasi permukaan yang tidak benar. Proses deteksi dini korosi dibawah lapisan cat bisa salah satu kandidat untuk mengurangi kerusakan lebih lanjut. Material senyawa cerdik adalah phenolphthalein (PP) diperlukan sebagai indikator terjadinya korosi. Konsentrasi senyawa PP divariasikan dengan sebesar 0,01% ; 0,1 % dan 1% yang diimbuhkan ke lapisan berbasis akrilik. Pengujian perfoma lapisan cat melalui pengujian kabut garam (ASTM B117-97) selama 240 jam. Metode visualisasi secara makro dilakukan untuk melihat kerusakan cat. Perfoma senyawa PP pada cat dengan konsentrasi 0,01% dan 1% memberikan indikasi bercak warna jingga di waktu ekspos 24 jam. Reaksi oksidasi dan reduksi (elektrokimia) berlangsung  pada daerah antar muka lapisan cat dan substrak baja melalui visualisasi warna jingga.

Abstrak: Permintaan akan Cat tembok pada pasar domestic yang tinggi menuntut penggunaan mesin yang selalu dalam kondisi prima, namun pada prakteknya sering terjadi kerusakan mesin. Salah satu komponen yang sering terjadi kerusakan adalah Poros Dudukan Bottom Plate Pada Mesin Pencampur Cat. Kerusakan tersebut mengharuskan dilakukannya penghentian proses produksi untuk melakukan perbaikan, hal ini menyebabkan kerugian waktu dan biaya bagi perusahaan. Tujuan penelitian ini dilakukan adalah untuk mencari penyebab serta mengetahui mekanisme terjadinya kegagalan yang terjadi pada Poros Dudukan Bottom Plate dengan spesifikasi material baja karbon S45C. Hasil fraktografi menunjukkan bahwa permukaan patahan merupakan struktur martensit temper yang mempunyai kekerasan cukup tinggi dan bersifat getas (brittle) sehingga tidak ada deformasi plastis pada permukaan patahan, tetapi dapat mengurangi ketahanan material terhadap beban kerja unidirectional bending dan mempunyai konsentrasi teganggan yang tinggi. Kemudian  dapat disimpulkan bahwa kerusakan yang terjadi pada Poros Dudukan Bottom Plate dari material S45C pada mesin pencampur cat disebabkan oleh patah lelah (fatique fracture), hal ini didukung oleh penjalaran patah dimulai dari satu sisi shaft dan daerah fatigue terjadi pada ¾ dari diameter Poros Dudukan Bottom Plate.Kata kunci: Poros Dudukan BottomPlate, Mesin Pencampur Cat, Analisa Kerusakan, Pengujian.

Abstrak : RTH atau taman kota menghasilkan banyak sekali limah dedaunan, walaupun sering dibersihkan, namun sampah dedaunan dibuang/dikembalikan ke lahan tanaman. Hal ini mengakibatkan limbah dedaunan berserakan, teronggok atau bahkan jatuh ke saluran pembuangan air (drainase) bisa menyebabkan terhambatnya aliran air pembuangan, yang menjadikan sarang penyakit dan bau busuk yang menyengat. Cara yang efektif penanganan limbah dedaunan adalah dengan memanfaatkannya menjadi briket. Namun bila dedaunan langsung dibriketkan, akan memberikan kesan yang kurang baik kepada pengguna, karena masih terlihat sampah dedaunan. Sebaliknya bila limbah dedaunan diarangkan, maka kesan sampah menjadi hilang. Pengarangan limbah dedaunan, secara mudah, sederhana dan murah, digunakan drum bekas, dibakar menggunakan udara terbatas kemudian didinginkan. Hal ini menimbulkan masalah, misalnya timbulnya asap hitam dan bau. Untuk mengatasi hal tersebut, dirancang bangun alat pengarangan menggunakan tenaga pemanas listrik walau mahal, namun  memberikan kesan bersih, praktis dan estetis. Sebagai tahap awal alat pengarangan ini dilakukan sekali uji coba menggunakan bahan baku sampah dedaunan, dengan pengisian bahan baku 80 % dan suhu pengarangan 250oC selama 5 jam. Hasil pengarangan yang baik hanya terjadi pada daerah yang dikelilingi pemanas listrik saja.Kata kunci: RTH, limbah dedaunan, pengarangan, alat pengarangan

Introduction: Common cold is Self-recovering respiratory diseases which can be caused by viral infection. As till date there is no treatment for the common cold and it is self-limiting in nature, symptomatic treatment is the only option. Symptomatic treatment of common cold with a single drug is not efficacious as compared to the multiple drug combination. Combination of antipyretic (Paracetamol), nasal decongestant (Phenylephrine) and anti-histaminic agent (Chlorpheniramine Maleate) can be used for the symptomatic treatment of common cold. This post marketing surveillance study was conducted to test the efficacy and safety for the fixed dose combination of Paracetamol 125mg, Phenylephrine Hydrochloride 2.5mg and Chlorpheniramine Maleate 1mg per ml in Indian patients of age 1 to 12 months.

Methodology: Out of 200 enrolled, 164 patients completed the study. Efficacy was evaluated by total symptom score (TSS) ranging from 0 to 10 where 0 was no symptom to 10 was the maximum tolerated symptoms. TSS was further extrapolated to four-point-Likert-type-symptom-severity-scale. Safety assessment was done by evaluation of adverse events reported by the patient.

Results: TSS was reduced from 5.91 on day 1 to 3.57 on day 3 and 1.47 on day 5. At day 3 and day 5 the percentage reduction in the TSS as compared to the baseline was 39.48 and 75.05 respectively. During the study only 8 episodes of ADRs were reported including sedation and drowsiness.

Conclusion: Combination of Paracetamol, Phenylephrine and Chlorpheniramine Maleate was found to be efficacious and safe for the treatment of common cold and allergic rhinitis.

Keywords: Paracetamol, Phenylephrine, Chlorpheniramine Maleate, Common Cold, Allergic Rhinitis.
