Evaluating Subtle Field Imprints in Water by Droplet Evaporation Method
Authors: Jerman Igor , Ratajc Petra , Pollner Bernhard
Published: August 2021

Abstract

Background: Even though water is regarded as something long understood and explained by conventional science â€“ many open-minded researchers know that it still hides many mysteries (water clusters, coherent domains, so-called memory, etc.). Many of these mysteries come to fore in ultra-high dilution (UHD) experiments and practices, where usually not even one molecule of the originating substances is left. Mostly, they can be tackled only by using the droplet evaporation method (DEM).1

Aim: One of the hypotheses of water memory suggests that through UHD (dilutions, shaking) the field of a substance is stably impressed into water. If this is true than we should be able to imprint also a field itself - not originating from a certain substance, but from other sources. Such imprint should be revealed by an appropriate research method.

Method: The DEM consists of monitoring dried water drops by dark field microscopy. It was discovered in the previous century by Ruth KÃ¼bler, a German artist, and further developed by Bernd-Helmut KrÃ¶plin, Minnie Hein, Berthold Heusel M. A. and Georg SchrÃ¶cker. It has also been used to research the still controversial special characteristics of ultra-high diluted aqueous solutions.2 It has been proved capable of demonstrating differences in subtle influences of an UHD (around 10-47 M, practically â€œpureâ€ water) of As2O3 on common wheat seeds. This method is therefore, capable of transferring certain, not yet fully understood or generally accepted subtle physical characteristicsof the solution to the remnant patterns after drop evaporation.3, 4

We used DEM to evaluate experiments on impressing the subtle field of five bioenergy healers and two so called â€œinformedâ€ objects (a glass and an â€œenergyâ€ card) into mineral or spring water with well-known characteristics. In all these experiments we also used control water that was of the same origin, but placed in a separate room. The DEM images were analyzed by special computer programs and statistically evaluated. No mother tincture of any kind was used.

Results: The results demonstrate that even such subtle fields can leave stable and reproducible imprints in water - made visually accessible by the remnant patterns after drop evaporation. The irradiated water samples were statistically different from the control. This difference can usually be observed even by a naked eye.

Conclusion

These results have several implications. They confirm as follows:

a) water memory â€“ the main background of UHD effects,

b) the possibility to imprint the fields into water,

c) the existence of subtle fields not yet generally recognized by physical community and

d) the capability of DEM to express the imprints.
Detection of nanostructures in solutions of Zincum metallicum and the vehicle lactose
Authors: Marzotto Marta , Bonafini Clara , Olioso Debora , Holandino Carla , Bonamin Leoni , Prosperi Davide , Marinozzi Maria , Bernardi P , Bellavite Paolo
Published: August 2021

Background: Nanoparticles (NP), because of their size (< 1Î¼m) and high relative surface area, are highly reactive forms of their source material with biological, chemical, optical, electromagnetic, and thermal properties different from larger bulk forms of the same material. It has been speculated that NPs can occur in homeopathic products as a function of trituration and shaking into glass containers. Moreover, the presence of sugars additives like lactose and of silicates leaked from the glassware are reported to stabilize the nanoparticles.1 Up to now some authors observed nanoparticles in highly diluted samples2, 3, but further studies are needed to know the nature of the NPs. Actually, nanostructures in the solutions may derive from the source materials but also from stuff contaminations and also may be constituted by nano-bubbles.4, 5 Moreover, the mechanism by which the nanostructures can be formed and the effect of serial dilution/succussions of the NPs suspension should be studied.6 Many tools are available to analyze the nanostructures both in solutions or in dried samples and these give complementary information about the concentration, stability, structure and chemical nature of the NPs. In the present report we describe preliminary observations obtained by the nanoparticle tracking analysis (NTA) in Zincum metallicum (Zinc met.) solutions at low-grade dilution/dynamization and their lactose controls. This study is part of a formal Brazilian-Italian inter-university collaboration.
Viscum album (L) extracts in cancer treatment: a systematic review of in vitro and in vivo studies
Authors: Carvalho Aloisio Cunha de , Bonamin Leoni Villano
Published: August 2021

Background: Several reviews about phytotherapy and homeopathy have been published in the last years, including Viscum album (VA.L). VA is a parasite plant whose extract has anti-cancer proprieties and is used alone or in combination with conventional chemotherapy.

Methods: We performed a systematic review about the in vivo and in vitro models described in the literature, including veterinary clinical trials. The literature was consulted from Pubmed database.

Results: There are several kinds of pharmaceutical preparations about VA and their active principles used in experimental studies, lectin being frequently studied (alone or as an extract compound). More than 50% of available literature about VA is related to the lectin effects. On the other hand, the effects of viscotoxins are less studied. Among the in vivo experimental studies about VA and its compounds, the B16 murine melanoma is the most used model, followed by Ehrlich, Walker and Dalton tumors. The results point to the apoptotic effects, metastasis control and tumor regression. Some veterinary clinical studies about the use of VA in the treatment of sarcoid, fibrosarcoma and neuroblastoma are quoted in literature too, with interesting results. Considering the in vitro models, our review revealed that NALM6 leukemia cells, B16 melanoma and NC1-H460 lung carcinoma were the most studied tumor models, apoptosis signals being the most important findings. Only one study verified immunoglobulin and interleukin production. All consulted papers were related to phytotherapy preparations only.

Conclusions: Although the literature about the anti-cancer activity of VA extract and its lectins is enough, there is a marked lack of information about viscotoxin activities and about the effects of homeopathic preparations of this plant on animal tumors and on in vitro cultivated tumor cells.

Particles of vacuum make it possible to determine the properties of elementary particles, but there is still a lot of work to develop the properties of particles of vacuum. The development of quantum electrodynamics and the standard model goes back 100 years. Meanwhile, the description of a lower level of masses and energies is 10 years old, and that is through the efforts of one person. When calculating the mass of elementary particles and their magnetic moment, linear formulas are used, which reduces the accuracy of the calculation. One must think about nonlinear corrections.

Cost of an unforced error in tennis: a statistical approach
Authors: Attray Hemant , Attray Saksham
Published: August 2021

The objective of this paper is to (1) introduce a scientific way of measuring the cost of an unforced error in tennis during various match situations and (2) to provide a basis for players and coaches to choose the right strategy among extremely cautious and adventurous playing styles based on a statistical approach. To do this, we analyzed a total of 2,490 different match situations. The results of this study show that the cost of an unforced error varies greatly depending on the match situation. Players are better served by playing a high percentage, low-risk game in situations when the cost of an unforced error is higher than the median cost and adapt a high-risk approach when it is lower than the median cost.

Authors: CAMPOS Angela Fernandes
Published: August 2021

Teaching chemistry employing a problem-solving approach is widely used and studies recommend it for different teaching levels since it allows students to develop concepts, procedures (know how to do), and attitudes (know how to be). From this standpoint and considering the importance of sugar cane, this study proposes a problem linked to an experimental activity classified as small research. The activities make it possible to explore chemical concepts from the reactions obtained in the analysis of iron (III) ions in a sample of “unrefined brown sugar. Iron (III) ions can be identified in solution, due to the emergence of a specific color, in the presence of adequate reagents. The experiment allows exploration of contents linked to chemical transformation and related to environmental and social approaches, involving an agricultural culture historically connected to Brazil, particularly the North-Northeast region

Ascorbic acid has aroused particular interest due to its antioxidant capacity, which can prevent oxidative reactions. Cyclic voltammetry stands out as one of the main electrochemical techniques for antioxidant evaluation. The cheese and ricotta whey are subproducts of the dairy, and have several components that allow its use in various foods. The enrichment of subproducts with essential substances in food may make its use even more attractive by industries. Therefore, the aim of this study was to evaluate the stability of ascorbic acid in cheese and ricotta whey using cyclic voltammetry. For this, the cheese and ricotta whey were collected from a dairy industry of the Vale do Taquari-RS and were fortified with ascorbic acid and its stability was evaluated according to the electrochemical profiles of the samples. With the data obtained, it was concluded that one of the factors affecting directly the stability of ascorbic acid was the pH, but more studies are needed to evaluate other interfering stability of vitamin C.
MODELLING OF MICROBIOLOGICAL METHOD OF OIL RECOVERY IMPROVEMENT
Authors: MILOVANOVICH Ekaterina V. , MAKSIMOVA (KUZNETSOVA) Svetlana N.
Published: August 2021

The problem of energy supply has been one of the most pressing issues for the humanity at all times. Oil is one of the most desired sources of energy. However, oil reserves are being depleted, and substantial amounts of subterranean residual oil cannot be extracted with the use of traditional methods, therefore requiring implementation of new technologies. The current paper suggests two mathematical models aimed to describe and predict implications of microbiological method of oil recovery improvement based on the currently available data, as well as to assess the efficiency of this method. The first model consists of partial differential equations that describe the process of expansion of microbial population through oil formation. The second model includes ordinary differential equations, describing growth and metabolism of bacterial cultures within the bottom-hole zone of the production well. The models were studied with the use of numerical grid and Euler methods. The modeling parameters were evaluated using the least squares method.

The broad application of cabofuran pesticide in sugar-cane cultures and its high toxicity makes it essential a search for new methods of preparing the samples to analysis of this pesticide in this culture. This work tried to optimize the solid-liquid extraction technique with low temperature partitioning (SLE/LTP) to determine the carbofuran in samples of sugar cane. The SLE/LTP technique, is a simple technique that shows advantages regarding other extraction techniques. Being so, a factorial experimental design 23 was created to study the simultaneous behavior of three factors in two levels. After this stage of split, to split, identification and qualification of carbofuran was analyzed the supernatant using the high efficiency of liquid chromatography with ultraviolet detector (HPLC/UV). The method ´s efficient to the extraction of carbofuran from sugar cane with percentages of recovery over the 73,0 %. After optimizing, the technique was applied in real samples of sugar cane in the region of Itumbiara-GO, Brazil. No carbofuran residues were found in the analyzed samples or they were below the detection limit. The SLE/LTP technique optimized to sugar cane, showed to be simple and efficient, being a economic method, consuming a little amount of sample and solvent extractor.

The pharmaceutical industry is one of the fastest growing economic sectors in the world. The existence of medicines for the most different diseases has made the use of these products grow vertiginously in recent years. When ingested these compounds are partially absorbed by the body, and part excreted in its original form. Sewage treatment plants (ETS), with processes based on biological degradation, can not remove these drugs from water. When it is returned to the environment, or intended for human consumption, this water contains small amounts of these compounds, which can cause deleterious effects to both humans and the environment. In this situation the use of photocatalytic methods can be an important alternative in the removal of these contaminants from the aquatic environment. This work studied the photodegradation of the antibiotic metronidazole (MNZ) in aqueous solution by photolytic and photocatalytic methods (POA) using ultraviolet light, hydrogen peroxide (H2O2) and titanium dioxide (TiO2). To investigate the photocatalytical process, an experimental design 23 was performed to evaluate the influence of the variables pH, hydrogen peroxide concentration and TiO2 concentration over the photodegradation of drug, which was spectrophotometrycally monitored in the UV-VIS region. The kinetic model of pseudofirst order described quite well the degradation behavior of the drug. The photocatalytical process only in presence of H2O2, the highest rate of degradation obtained was 8.66% at pH 4. In the heterogeneous photocatalysis experiments the highest degradation rate of the MNZ was 72.1% when TiO2 was used in concentration of 100 mg∙L-1, H2O2 at the concentration of 1000 mg∙L-1 at pH 10. The statistical analysis of the results showed that in the heterogeneous photocatalysis experiments with TiO2 only the pH/H2O2 interaction had no significant effect. Cytotoxicity assays employing Artemia salina as bioindicator showed a 90% reduction in sample toxicity after the photocatalytical treatment.

This paper examined inadequate library services as a challenge to 21st century education in a developing economy. The paper portrayed the library as a collection of books and other information materials in various formats, properly arranged for the promotion of human knowledge, stressing that the 21st century library, with the integration of ICT and as a custodian of both books and non-book materials in diverse formats, is expected to have quantum of information available to users at all times, in order to promote constructive education. The paper takes the position that for Nigeria’s educational system to impact the knowledge and skills desired for development that endures, adequate library services must be provided at all levels of education. The paper reviewed that most libraries in Nigeria are plagued with outdated materials and lack the required facilities and resources to satisfy users’ needs, which result in inadequate library services, poor academic performance in entrance examinations, and poor reading culture which negatively affects educational development. This paper presents the absence of technological literacy, inadequate workforce, scarcity of sufficient resources, poor funding and power outage as causes of inadequate library services. The paper therefore recommends that the library staff should be trained and retrained to initiate and manage technological tools. The library should be stocked with required materials. Inter-library services should be upheld and an alternative means of power should be provided to avoid power interruption and its associated consequences on library services for the proper functioning of 21st century education.

Zencefil (zingiber officinale roscoe), çoğunlukla Hindistan, Çin, Nijerya, Sierra Leone, Endonezya, Bangladeş, Avustralya, Fiji, Jamaika ve Nepal gibi ülkelerden gelen ve dünyanın çeşitli yerlerinde yetiştirilen zencefilgiller (zingiberaceace) ailesinden olan, baharat olarak da anılan yumru köklü sarımtırak bir bitkidir. Kök, gövde ve yaprakları olan bu bitki; taze kök, kuru kök, öğütülmüş toz, turşu, zencefil yağı, zencefil şekerlemesi, zencefilli su veya zencefil çayı olarak tüketilebilmektedir. Ayurvedik, Hint ve Çin tıbbında, soğuk algınlığını, sindirim şikâyetlerini, mide bulantısını önlemek ve dolaşımı arttırmak için bitkisel ilaç olarak binlerce yıldır kullanılmış ve Roma, Yunan ve Osmanlı tıp tarihi kayıtlarında tıbbi bir bitki olarak kullanıldığı gösterilmiştir. Günümüzde kemoterapi kaynaklı, ameliyat sonrası ve hamilelikteki bulantı ve kusmayı önlemede; soğuk algınlığı tedavisinde, eklem hastalığı ve astım tedavisinde, kolorektal ve prostat kanseri riskini azaltmada, dismenore, diyabet ve yağ metabolizması üzerine etkisinin olduğu, vücut kompozisyonunu ve egzersiz performansını arttırdığını gösteren birçok çalışma vardır. İçerdiği biyoaktif bileşenleri ve kimyasal yapısı incelendiğinde yapısında bulunan uçucu ve uçucu olmayan yağ asitleri gibi iki önemli fitokimyasal etkenler zencefilin etkilerini ortaya koymaktadır. Çalışmalarda, zencefilin birçok sağlık sorunu üzerine olumlu etkilerinin görülmesine rağmen; en etkili dozunun kanıtlanması için daha fazla klinik araştırmaya ihtiyaç duyulmaktadır.

Published: August 2021

Bilindiği gibi; turizm ve seyahat sektörünün gelişiminde ulaştırmanın her zaman için önemli bir payı bulunmaktadır. Kişinin bulunduğu mekândan ayrılarak tekrar dönmesi ancak bir ulaşım biçimini kullanmakla mümkündür. Havayolu taşımacılığı da, kitlesel turizm hareketlerinin ivme kazanmasında önemli bir etkiye sahiptir. Bu çalışmanın amacı, Türkiye özelinde havayolu taşımacılığı ve tur operatörlüğü faaliyetlerinin kısa bir analizini yaparak ardından ikisi arasındaki doğrusal ilişkiyi ortaya koymaktır. Bu kapsamda, basılı ve dijital ortamlardan elde edilen ikincil veriler ışığında havayolu taşımacılığı bağlamında Türk tur operatörlüğünün gelişimi üzerinde durularak yaşanan olumlu ve olumsuz gelişmeler bazı örneklerle anlatılmaktadır. Yapılan derleme ışığında, 1960’lı yıllardan başlayarak Almanya’da çalışan Türk işçilerine dönük sefer düzenlemekle işe başlayan bazı firmaların ilerleyen yıllarda paket tur düzenleyen tur operatörleri sınıfına geçerek özellikle Almanya-Türkiye arasındaki turist akışının hızlanmasında önemli katkıda bulundukları görülmektedir. Çalışma, bu yönüyle, ulusal turizm literatüründe eksikliği hissedilen Türk kökenli tur operatörlüğünün ulusal turizm sektörüne paralel olarak gelişimi üzerindeki doğrudan etkisini de göstermektedir.

Dünyada havadan hasta naklinin gelişimi yaklaşık bir yüzyıllık sürece dayanmaktadır. En erken kaydedilmiş uçak ile tahliye, Birinci Dünya Savaşı sırasında Sırp hastaların modifiye edilmemiş bir Fransız savaş uçağı gerçekleştirilmiştir.
Hasta nakillerinde çok eski zamanlardan itibaren kullanılan ambulanslar her geçen gün gelişen teknoloji ile birlikte modifiye edilmekte, buna istinaden nakiller daha hızlı ve güvenli şekilde sağlanabilmektedir. Bununla birlikte havacılık sektöründe yaşanan gelişmeler neticesinde son yıllarda hava ambulanslarının kullanımı da giderek artmaktadır. Türkiye’de hem T.C Sağlık Bakanlığı hem de özel havacılık firmaları tarafından işletilen hava ambulanslarının sayısının artmasına bağlı olarak hastalar hem ülke içinde hem de ülkeler arasında güvenle nakledilebilmektedir. Ayrıca havadan hasta naklinde görev alan personelin insan vücudunun yüksek irtifa ve basınç ve altında ne gibi tepkiler verebileceğini bilmesi için havacılık fizyolojisi konusunda yetkin olması büyük önem arz etmektedir.
Bir hastanın ya da kazazedenin, olay yerinden ve/veya sağlık kuruluşundan ileri tetkik ve tedavi yapılabileceği bir üst basamak sağlık kuruluşuna sevkinde zaman çok büyük önem arz etmektedir. Nitekim bazı hayati öneme haiz tıbbi durumlarda saniyeler bile çok önemli olabilmektedir. Bu nakillerde kullanılan araçların önemi de burada ortaya çıkmaktadır.
Bu çalışmada Türkiye’de hava ambulans sektörünün gelişimi incelenmiş olup ayrıca Türkiye’ de havacılık sektöründe hem T.C Sağlık Bakanlığı hem de özel havacılık firmaları tarafından işletilen hava ambulans kullanımına ilişkin değerlendirmeler yapılmıştır.
