Assessment of shutdown dose rates at the ESS target cooling system using SCALE6.2
Authors: Chambon Amalia , Klinkby Esben , Emås Leif , Lauritzen Bent
Published: July 2020

The production of high-energy neutrons at the European Spallation Source through the spallation process may cause an erosion of the tungsten target. The eroded particles could be released into the target helium cooling system which contains four kind of filters. Among them, the auxiliary filters called “getters” are designed to capture volatile elements and remaining dust. In this work, the ORNL’s SCALE6.2 modelling and simulation suite for nuclear safety analysis is applied to assess shutdown dose rates and determine if added shielding and/or robotic arms are needed for their maintenance. SCALE6.2 is well adapted to treat this problem as it allows for isotope selection regarding source term calculation. Dose rates are determined by an ORIGEN2 source term and a MAVRIC shielding sequence calculation. As SCALE6.2 is non-standard software for ESS, the results are verified against MCNP, which is the baseline tool for neutronics analysis at ESS. Dose rate calculations show that additional shielding and/or robot arm are not needed to remove the getters after 3 months of cooling time, following 5400 h of operation at 5 MW beam power. At a distance of 1 mm from the getter, the dose rate is 0.2 mSv/h in the most conservative estimation.
L3-subshell alignment of Ag in collision with 15 keV electrons
Authors: Hu Pengfei , Wang Xing
Published: July 2020

It is of great importance to study the alignment of atoms in collision process in elementary analysis with a Particle Induced X-ray Emission (PIXE) technique. The measurement of alignment can also offer an effective testing ground for developing theory models in ionization process. The typical L X-ray spectra are measured for Ag thin target by 15 keV electron impact at emission angles from 0° to 25°. Angular dependence of intensity ratios L α/L β1, L β2/L β1 and L γ/L β1 are investigated as a function of the second-order Legendre polynomial P2(cos θ). This study found that L β2 line exhibits anisotropic emission spatially, while the emission of L α, L β1 and L γ1 lines is isotropic. The results are interpreted by the influence of the Coster-Kronig (CK) transitions on the spatial distribution of X-ray emission. The anisotropy parameter β for L β2 lines is obtained experimentally and consequently the alignment degree A20 for L3 subshell is determined by taking CK transition into account. Namely, the alignment does exist in L3-subshell for atomic ionization by electron impact. The measurements offer an evidence to the existence of alignment for atomic ionization in electron-impact process.

COMMUNITY ACCEPTABILITY TO THE SALAFI MOVEMENT
Authors: Setiawan Wahyu , Midia Fredy Gandhi
Published: July 2020

The study of Salafi is generally focused on the perspective of social movements with the political opportunity structure, resources theory, and collective action frames. The three approaches to social movement theory lead to the same estuary, which is an analysis of emerging factors and the development of a social movement. Unlike the previous studies, this article focuses on the acceptance of the Islamic community's acceptability patterns to the Salafi movement. The interesting phenomenon of this movement is the so massive infiltration occurring. The community is so rapidly accepting the style and the system of sustainability offered by various Salafi groups. This article uses a sociological approach to the basis of structural-functional and interactionist-symbolic theories of experience in both the individual and collective levels of the followers of Salafi. Methods of collecting data through interviews, observations, and documentation with the research subject of 30 members of the Salafi group are not grass-root. The results showed that structuralist-functionally, the phenomenon of public acceptability due to the currents of modernity, shifting the concept of the family, shifting the meaning of religious authorities, and ease of access to information technology. Symbolically-symbolic, the phenomenon is the result of individual interaction with the social environment and the search for alternative religious identity.

Published: July 2020

Abstract

This research analyses the concept of leadership within transnational Islam tradition in Indonesia and their response towards democracy, particularly within three largest transnational organizations of Jama’ah Tabligh, Jama’ah Tarbiyah, and Hizbut Tahrir Indonesia (HTI).  Based on an extensive literature study and in depth interviews, this research found that: first, leadership concept in the tradition of (1) Jamaah Tabligh is called “Amir” which is appointed through a dialogue (musyawarah). The Amir is responsible to preach ‘the da’wah ‘ala> Minhaj an-Nubuwwah (proselytizing Islam using Prophetic methods) through ‘khuru>j fi> sabi>lilla>h; (2) Jama’ah Tarbiyah is called “Majlis Syuro” as the highest body of the Islamic party which functions as “ahlul halli wal ‘aqdi” (the consultative assembly) in its political movement represented by Partai Keadilan Sejahtera (Prosperous Justice Party/ PKS); and (3) HTI is called “Khalifah” that calls for the system of ‘Khila>fah ‘ala> Minha>ji an-Nubuwwah’. Second, those three organizations have divergent responses regarding the practice of democracy in Indonesia. The responses are (1) Jamaah Tabligh chooses to be apolitical and let its followers whether to participate in the democracy or not; (2) Jamaah Tarbiyah supports the democracy system by establishing Prosperous Justice Party (PKS), and (3) HTI opposes democracy because the concept is born from the capitalist ideology, a kufr system as it created by human and is not taken from Shari’ah concept..

Published: July 2020

In principle, civil procedure consists of court rules with the overriding purpose of enabling the court to process a civil case right from the process of commencement of action to its disposal in an efficient and expeditious manner. At this point in time, however, there is a scarcity of publications in Malaysia on the subject of civil procedure (tatacara mal) of the Shariah courts. In comparison, there are sufficient texts on the subject of civil procedure of the civil courts and also on the substantive aspects of Syariah laws. Such a situation demands serious attention especially when Syarie lawyers and undergraduate students enrolled for courses relating to Syariah or Law (or a double-degree programme of Syariah and Law) are in need of a book on civil procedure in the Syariah Court that incorporates the substantive aspects of civil litigation and drafting skills.

Authors: Matkovska M.
Published: July 2020

The article represents the results of research for 2016–2018 in the condition of Western Forest-Steppe of Ukraine. The yield of winter barley obtained under various fungicide treatment and three diff erent fertilization dose rates of (N40P30K40, N80P60K80, N120P90K120) was compared in the study The influence of mineral fertilizers on the diseases development was studied along with fungicides application effi ciency for the following diseases of Wintmalt variety of winter barley: net blotch, powdery mildew, and spot blotch. Three major diseases were observed in barley crops during the research years: net blotch, powdery mildew and spot blotch.
It has been established that increasing the level of fertilization contributes to the increase of disease development in barley crops. Thus, the highest level of net blotch (51.7 %), spot blotch (15.4 %) and powdery mildew (17.5 %) was observed on the variant of N120P90K120. High effi ciency of the studied fungicides was established. The highest technical effi cacy of the preparations was obtained on the variant of Systiva 1,5 l/t + Adexar Plus 1,0 l/ha in the stage of the fl ag leaf.
The results of the studies showed that the highest yield (9.27 t/ha) of the Wintmalt variety of winter barley under the studied conditions was obtained on the variant of complete mineral fertilization N120P90K120 and the treatment of fungicide plant protection by Systiva 1.5 l/t (BBCH 00) + Adexar Plus (BBCH 39) 1.0 l/ha.
The fungicide protection of Systiva applied to the seeds along with the pre-sowing treatment, ensured a yield increase of 0.64 t/ha, 0.68 t/ha and 0.77 t/ha on the N40P30K40, N80P60K80, N120P90K120 respectively. The highest yield increase compared to the control was obtained on the Systiva 1.5 l/t (BBCH 00) + Adexar Plus (BBCH 39) 1.31–1.69 t/ha depending on the dose rates of fertilization. Fungicide protection is recommended to apply to all the studied fertilizers dose rates, but the highest yield increase from the fungicides was obtained on N 120P90K120.

The results of the study on foliar nutrition infl uence on the productivity of sunfl ower hybrids are presented in the article. The research was carried out in the period 2018–2019 in the conditions of the experimental fi eld of VNAU on the basis of NRF "Agronomichne," located in the village of Agronomichne, Vinnytsia region. The research studied two hybrids of sunfl ower mid-early ripenessgroup: Basfora and Sanai MR in the application of foliar nutrition microfourings Vanguard R Sunfl ower which was introduced into the phase 3–4 and 6–8 pairs of leaves. Thesoil on the experimental plot is a gray forest middle-loamy. According to the results of measurements, the height of plants in Basfora sunfl ower hybrid on control, on average for two years of research was 181.0 cm, and Sanai MR hybrid – 169.5 cm. When applying microfertilizers in phase 3–4 pairs of Bosphora leaves – 186.0 cm, Sanai MR – 174.5 cm, in phase 6–8 pairs of Bosphora leaves – 187.5 cm, Sanai MR – 174.5 cm and with double application microfertilizers in phase 3–4 and 6–8 leaves – 191,0 and 175,0 cm, respectively for the hybrids of Bosphora and Sanai MR. Foliar nutrition reduces the number of plants aff ected by gray rot by 1.2–2.5 % for the Bosphora hybrid and 1.0–1.7 % for the Sanai MR hybrid and white rot – Bosphora by 1.6–2 in the studied sunfl ower hybrids, 1 % and Sanai MR – 0.6–1.4 %. Carrying out foliar nutrition contributed to the growth of the mass of seeds from one plant. In particular, application of microelements Vanguard R Sunfl ower in phase 3–4 pairs of leaves provides the following value of seed weight from one plant: Basfora – 45.0 grams, Sanai MG – 40.5 grams, introduction in phase 6–8 pairs of leaves 44.7 and 39 7 grams, and two-day introduction of this microelement in phase 3–4 and 6–8 pairs of leaves – 48.6 and 42.6 grams.
It is also noted that the implementation of foliar nutrition provided an increase in the number of seeds in the infl orescence (basket). On control (without nutrition), the number of seeds from the basket, respectively, was 698 and 663 pieces, for the hybrid of the Bosphora and Sanai MR. The lowest productivity of the studied sunfl ower hybrids was formed on the control (without foliar feeding): Bosphora – 2.85 t/ha and Sanai MR – 2.79 t/ha. The highest productivity on sunfl ower crops in the studied hybrids was obtained under double foliar nutrition of sunfl ower with microfertilizers Avanhard R in the phase 3–4 and 6–8 pairs of leaves and on average during the years of research it amounted to 3.19 t/ha for the Basfora hybrid and 3.14 t/ha for the Sanai MR hybrid, which is 0.44 and 0.35 % more than the control.

Authors: Senyk I.
Published: July 2020

Botanical composition of grasses is one of the most important indicators the biological value and quality of the obtained hay and pasture forage, the longevity of hayfi elds and pastures depend on. The issue of changing the botanical composition of agrophytocenoses is especially important in the context of global climate change, which in recent decades is also manifested in the territory of Ukraine, as it is possible to establish the most adapted species of legumes and cereals to adverse weather conditions and to identify eff ective technological methods of managing these processes for maximum conservation economically valuable species in the herbage.
The purpose of the research is to establish the infl uence of diff erent ways of sowing of clover and alfalfa cereal crops agrophytocenoses on the formation of their botanical composition.
Field studies have established diff erent eff ects of conventional in-line, cross-section and cross-sectional methods of sowing on the formation of botanical composition of grass mixtures of clover meadow (Trifolium pratense) varieties Sparta and Pavlyna with timothy meadow (Phleum pratense) and fenugreek multifl oral (Lolium multifl orum) and of agrophytocenoses of alfalfa of Sinyukha and Seraphima sowing varieties with reed fire (Festuca arundinacea Schreb) and middle wheatgrass (Elytrigia intermedia).
For the average of four years of life of clover and alfalfa cereal crops agrophytocenoses, the highest proportion of legume component was observed with split-cross sowing – 51.6 % for Sparta, 53.1 % for Pavlyna, 60.3 % for Seraphima and 61.6 % for the Sinyukha variety. In the fourth year of life (the third year of use) of sowed leguminous-cereals agrophytocenoses, the preservation of the legume component was 14.6–15.5 % in clover-cereals grass mixtures with the Sparta variety and 16.0–16.8 % with the Pavlyna variety. In alfalfa grasslands, these indicators were 54.0–55.1 % with Seraphim and 55.0–56.2 % with Sinyukha. Among the studied varieties of clover meadow and alfalfa sowing proved better in the conditions of the Forest Steppe of western Pavlyna and Sinyukha.
Cross-sectional and divided cross-sectional sowing of legumes and cereals mixtures proved to be better compared to conventional row crops in terms of conservation of economically valuable grass species.

Published: July 2020

The research aimed to study the productivity of blackberry foreign varieties (Rubus subgenus Rubus Watson) in the Right-Bank Forest-Steppe part of Ukraine as they are attractive for production due to their fruit taste and appearance. The task was to establish the beginning and duration of fruiting of blackberry varieties, to determine the yield level and the quality of the berries. A fi eld experiment was conducted on the experimental fi eld of the Scientific and Research Center of BNAU to assess the productivity of blackberry varieties. The studies were started in the spring of 2017 on blackberry seedlings with growing the culture in vitro in the biotechnological laboratory of the university. The tests included 5 varieties with climbing shoots: Smoothstem, Thornfree, Black Satin, Triple Crown, Arapaho. According to the results of observations, it was found that for two years of fruiting among the studied varieties, the earliest production was received in the Arapaho variety, in the first decade of July. Triple Crown, with the fi rst fruits ripened on August 2, was characterized by late fruiting. The Triple Crown variety diff ered by the longest period of berry coming – 35 days. The yield obtained in a year after planting is not an indicator of long-term crop yields. However, the Triple Crown variety diff ered by the highest yield in the fi rst year of fruiting, with an average of 3.7 kg of berries obtained from a bush. High yields were also observed in the Smoothstem variety. Black Satin variety was characterized by the high level of yield growth for over two years of fruiting, which amounted to 80 %. The largest in the fi rst years of fruiting were Triple Crown fruits with an average weight of 11.1 g. The maximum weight of individual berries of this variety reached 17.7 g. The Arapaho variety also stood out with its large fruits of 8.5 g on average. Some fruits reached a maximum weight of 12.1 g.

Ukrainian Chernozem Fertility Reproduction under Soil Conservation Agriculture
Authors: Kravchenko Yu.
Published: July 2020

In Ukraine 57.5 % of agricultural land is subjected to erosion with 10–24 million tons of humus, 0.3–0.96 million tons of nitrogen, 0.7–0.9 million tons of phosphorus and 6–12 million tons of potassium lost annually. Degradation processes are also common on chernozems, which cover about 60 % of the Ukrainian territory.

The aim of the research is to defi ne the most eff ective soil conservation practices and legislative decisions aimed to conservation/recovering the Ukrainian chernozem fertility. The experimental data of the agrochemical certifi cation of Ukrainian lands, data from scientifi c papers, stock and instructional materials as well as our own fi eld and laboratory studies were used.
It has been established that the long-term use of deep subsurface tillage on typical chernozem increases, compared with plowing, the content of 10–0.25 mm of air-dry and water-resistant aggregates, the bulk density, soil water storages, water infi ltration rates, the content of mobile phosphorus and exchangeable potassium, pHH2O, CaCO3 stocks, the contents of humic and fulvic acids, molecular weights of humic acids – by 5.5 and 3.06 %; 0.05 g/cm3; 25.5 mm; 22.6 mm/h; 0.1 and 3 mg/100 g of soil; 0.03 pHH2O; 18 t/ha, 0.02 and 0.04 %, 91195 kDa, respectively. Fertilizers may contribute to the crop yields increase from by 60% in the Polissya, by
40 % – in the Forest Steppe, by 15 % – in the Wet Steppe, by 10 % – in the Dry Steppe and by 40 % – in the Irrigated Steppe areas. In soil-conservation rotations, the crop placement and alternation are advisable to combine with strips or hills sowing, taking into account the local relief features; soil alkalinization, applying anti-erosion structures. Ukrainian agriculture will receive additional 10–12 million tons of forage units or 20–22 % from all fodder in a fi eld agriculture under increasing 8–10 % of arable lands for intercrops. It is advisable to mulch the eroded chernozems of Ukraine depending on their texture composition: 1.3 t/ha of mulch for sandy and
loamy soils, 1.9 t/ha – for sandy and 1.1 t/ha – for loamy soils.
The implementation of soil conservation agriculture can minimize some soil degradation processes and improve eff ective soil properties required to realize the biological potential of cultivated plants.

Published: July 2020

Background and Objectives Snoring is the most common symptom of obstructive sleep apnea (OSA) and is caused by turbulent airflow due to narrowing of the upper airways. In patients with positional OSA, a change in sleep posture from supine to lateral is known to reduce snoring and sleep apnea. This study was performed to compare changes in snoring sound intensity and formant frequencies according to sleep position.Subjects and Method A total of 19 patients (male: 18; female: 1) diagnosed with positional OSA by polysomnography (PSG) were enrolled in this study. The snoring sounds recorded during PSG were analyzed acoustically and compared according to sleep position (i.e., supine vs. lateral).Results Snoring disappeared on changing sleep position in five patients, all of whom had Apnea-Hypopnea Index (AHI) <15. In other patients, the snoring sounds tended to decrease with posture change, and the degree of decrease was inversely proportional to AHI (p=0.015) and respiratory disturbance index (RDI) (p=0.013). Formant frequencies 1, 3, and 4 (F1, F3, and F4, respectively) decreased when sleeping in the lateral position (p=0.02, 0.03, and 0.01, respectively).Conclusion In patients with positional OSA, a change in sleep posture from supine to lateral during sleep reduced the intensity and frequency of snoring sound.

AT "RATAHIWI", we have endeavoured to apply the findings and observations of research workers and farmers, and to do some constructive thinking and observation of our own. We were fortunate in starting out with no appreciable liabilities, but more fortunate not to have spare cash; this gave us an incentive to make some. The human being is so constructed that he must have something against which to strive, in order to be happy. A farm can be developed indefinitely on a basis of maintaining profitability in relation to investment, which means that as the undertaking grows the total income must also grow. This process can give the satisfaction of achievement to the farmer and a better standard of living for his family. If farming in New Zealand was running at even half capacity, there would be no balance of payments problems.

COMPARATIVE PHOTOSYNTHETIC EFFICIENCY OF SOME NATIVE AND INTRODUCED GRASSES
Authors: Scott D. , Menalda P.H.
Published: July 2020

THE ABILITY OF PLANTS to capture light energy is the key to the continual survival of all life. Light absorbed by the green parts of plants is used to fix carbon dioxide from the air and convert it into energy-rich compounds which are then translocated to other parts of the plants. There they may be stored or used to provide energy for growth processes with consequent release of carbon dioxide. This energy from sunlight which is stored in biochemical compounds is the only source of energy for growth and is only a small portion of the total incident sunlight. The rate at which plants can take up carbon dioxide is thus a good measure of the rate at which plants absorb useful energy. However, in practice, only the net exchange of carbon dioxide which results from the uptake by photosynthesis and release by respiration can be measured.
COVID-19: Is it time to revisit the research on calcium channel drug targets?
Authors: Balasubramanyam Muthuswamy
Published: July 2020

As the COVID-19 outbreak continues to endanger global health and hamper the world economy, there are concerns and reconsiderations for medication taken by patients with cardiometabolic disorders as they are more vulnerable to COVID-19. While several articles and perspectives have dealt with the concern and safe continuation of antihypertensive drugs, there is paucity of information on calcium channel blockers (CCB). Despite the biology of calcium channel involvement in virus entry and replication, the beneficial effect of CCB is somewhat speculative and only preclinically evident. This commentary focusses on the clinical research on CCB in the context of COVID-19.

Data of 141 young patients with ischemic stroke, including 30 people with atherothrombotic stroke, 35 with cardioembolic, 36 with lacunar and 40 ones with cryptogenic stroke were analyzed. The control group included 40 young patients without stroke. Results. The frequency of polymorphism MTHFR C 677T (OR = 6,7; 95 % CI: 1,20–37,45: р = 0,027), allel T (OR = 2,29; 95 % CI: 1,10–4,74; р = 0,028) and the level of homocysteine are higher among stroke patients.
Tension-type headache as most frequent and often erroneous diagnosis
Authors: Filatova E. G. , Merkulova D. M.
Published: July 2020

Tension-type headache (ТТН) is the most frequent and at the same time the most difficult to diagnose type of primary headache. The clinical features of TTH are nonspecific, and a similar phenotype can be observed in migraines with a relatively mild course, psychogenic headache, and secondary headaches. Often associated with a misdiagnosis is treatment failure. Three generally accepted approaches to therapy are presented in the article: behavioral therapy, acute treatment that have a high level of evidence on the basis of randomized controlled trials, as well as preventive therapy. The place of ketoprofen was determined, including various dosage forms of the drug – injectable, oral (tablets, powders, capsules), which allows it to be used to quickly and effectively relieve acute attacks of TTH.

Villages received very serious attention from the Government, with the Government issuing and enacting Law number 6 of 2014, on Villages, as well as establishing Village financial assistance, which is budgeted and allocated in the state budget annually. This financial assistance increases every year in line with the needs and problems of the current village. So the impact of that is where the Village Government in this case the Village Head and his staff must be able to manage the Village Fund effectively and efficiently, and transparently, in order to realize the accountability of Village Fund management. The researcher is interested in the extent to which the role of the village head can improve the performance of village fund management apparatus in the village of Tegalbarang, Tegalbarang sub-district. Tegalbarang village, a few years earlier was included in the IDM category which was lagging behind, with the financial assistance of the Village, the Village and the Village community could utilize the Village Fund to develop the Village Development Infrastructure, so that now Tegalbarang Village was included in the developing Village category based on the Regulation of the Ministry of Disadvantaged Regions number 6 years 2016, and in 2017, Tegalbarang Village is included in the developing village category. This study uses a descriptive qualitative method, with an inductive approach, with the theory used in this study is the Role theory, and related to the apparatus performance theory, as well as theories about the Village and Village Fund management. Conclusions can be explained that with the Prannya Village Head as the person in charge of Village Fund management, where the management is carried out by following and based on the District Head Regulation number 100 of 2017, on Guidelines for Village Financial Management, the performance of the Village apparatus in Village Fund management can be said to be very good, and the constraints that arise can be overcome by deliberation between the Village, the Camat and the Village Facilitation that conducts assistance for the Village Fund assistance in Tegalbarang Village.
Democracy, Authoritarianism, and COVID-19 Pandemic Management: The Case of SARS-CoV-2 Testing
Authors: Petersen German
Published: July 2020

A strand of political economy literature expects democratic governments to be more effective than their authoritarian peers in the management of catastrophic situations (famines, pandemics). The ongoing COVID 19 pandemic offers an interesting setting to test this expectation, in particular to explore whether democracies are more preventive and therefore massify SARS-CoV-2 testing. Analyzing data from 85 countries, the more democratic a country is, not necessarily the more tests it runs. The relationship is rather curvilinear, best described by a U, with low and high levels of democracy associated with the massification of testing, and medium levels associated with low testing. Besides testing democracies and non-testing authoritarianisms, there are testing authoritarianisms —basically rentier states— and non-testing democracies; anocracies tend to be non-testing. The variance in testing seems to be also partially explained by GDP per capita and government effectiveness, but surprisingly unrelated to the length of the pandemic in a country.
Deep learning to de-risk reserve estimation
Authors: Nishitsuji Yohei , Masaya Shogo
Published: July 2020

Oil and gas companies evaluate the possibility of finding oil and gas fields carefully more than ever because it has been difficult to find gigantic discoveries which directly leads to their capital. Since a conventional evaluation contains human interpretation, luck and uncertainties, a variety of ranges of the reserves are often inferred from different interpreters given even identical dataset and conditions. As a consequence, there are differences between actual reserves and evaluated reserves. In this paper, using certain cases of how much actual reserves are deviated from interpreted reserves, deep learning is applied to mitigate such differences for unknown data which do not have actual reserves information. We find that our approach stably predicts the actual model by decreasing the misfit between the human and actual in comparison with the validation data on our workflow. The approach could be used to de-risk reserves estimation without changing traditional way of interpretations.
Structural and Bioactivity Characterization of Filipin Derivatives from Engineered Streptomyces filipinensis Strains Reveals Clues for Reduced Haemolytic Action

Published: July 2020

The rise in the number of immunocompromised patients has led to an increased incidence of fungal infections, with high rates of morbidity and mortality. Furthermore, misuse of antifungals has boosted the number of resistant strains to these agents; thus, there is urgent need for new drugs against these infections. Here, the in vitro antifungal activity of filipin III metabolic intermediates has been characterized against a battery of opportunistic pathogenic fungi—Candida albicans, Candida glabrata, Candida krusei, Cryptococcus neoformans, Trichosporon cutaneum, Trichosporon asahii, Aspergillus nidulans, Aspergillus niger, and Aspergillus fumigatus—using the Clinical and Laboratory Standards Institute broth microdilution method. Structural characterization of these compounds was undertaken by mass spectrometry (MS) and nuclear magnetic resonance (NMR) following HPLC purification. Complete NMR assignments were obtained for the first time for filipins I and II. In vitro haemolytic assays revealed that the haemolytic action of these compounds relies largely on the presence of a hydroxyl function at C26, since derivatives lacking such moiety show remarkably reduced activity. Two of these derivatives, 1′-hydroxyfilipin I and filipin I, show decreased toxicity towards cholesterol-containing membranes while retaining potent antifungal activity, and could constitute excellent leads for the development of efficient pharmaceuticals, particularly against Cryptococcosis.
A Short Review on the Effect of Surfactants on the Mechanico-Thermal Properties of Polymer Nanocomposites
Authors: Shamsuri Ahmad Adlie , Md. Jamil Siti Nurul Ain
Published: July 2020

The recent growth of nanotechnology consciousness has enhanced the attention of researchers on the utilization of polymer nanocomposites. Nanocomposite have widely been made by using synthetic, natural, biosynthetic, and synthetic biodegradable polymers with nanofillers. Nanofillers are normally modified with surfactants for increasing the mechanico-thermal properties of the nanocomposites. In this short review, two types of polymer nanocomposites modified by surfactants are classified, specifically surfactant-modified inorganic nanofiller/polymer nanocomposites and surfactant-modified organic nanofiller/polymer nanocomposites. Moreover, three types of surfactants, specifically non-ionic, anionic, and cationic surfactants that are frequently used to modify the nanofillers of polymer nanocomposites are also described. The effect of surfactants on mechanico-thermal properties of the nanocomposites is shortly reviewed. This review will capture the interest of polymer composite researchers and encourage the further enhancement of new theories in this research field.
