Authors: Tsai Shang-Min , Malik Matej , Kitzmann Daniel , Lyons James R. , Fateev Alexander , Lee Elspeth , Heng Kevin
Published: December 2021

We present an update of the open-source photochemical kinetics code VULCAN to include C–H–N–O–S networks and photochemistry. The additional new features are advection transport, condensation, various boundary conditions, and temperature-dependent UV cross sections. First, we validate our photochemical model for hot Jupiter atmospheres by performing an intercomparison of HD 189733b models between Moses et al., Venot et al., and VULCAN, to diagnose possible sources of discrepancy. Second, we set up a model of Jupiter extending from the deep troposphere to upper stratosphere to verify the kinetics for low temperature. Our model reproduces hydrocarbons consistent with observations, and the condensation scheme successfully predicts the locations of water and ammonia ice clouds. We show that vertical advection can regulate the local ammonia distribution in the deep atmosphere. Third, we validate the model for oxidizing atmospheres by simulating Earth and find agreement with observations. Last, VULCAN is applied to four representative cases of extrasolar giant planets: WASP-33b, HD 189733b, GJ 436b, and 51 Eridani b. We look into the effects of the C/O ratio and chemistry of titanium/vanadium species for WASP-33b, we revisit HD 189733b for the effects of sulfur and carbon condensation, the effects of internal heating and vertical mixing (K
zz) are explored for GJ 436b, and we test updated planetary properties for 51 Eridani b with S8 condensates. We find that sulfur can couple to carbon or nitrogen and impact other species, such as hydrogen, methane, and ammonia. The observable features of the synthetic spectra and trends in the photochemical haze precursors are discussed for each case.
Evolution of Accretor Stars in Massive Binaries: Broader Implications from Modeling ζ Ophiuchi
Authors: Renzo M. , Götberg Y.
Published: December 2021

Most massive stars are born in binaries close enough for mass transfer episodes. These modify the appearance, structure, and future evolution of both stars. We compute the evolution of a 100-day-period binary, consisting initially of a 25 M
⊙ star and a 17 M
⊙ star, which experiences stable mass transfer. We focus on the impact of mass accretion on the surface composition, internal rotation, and structure of the accretor. To anchor our models, we show that our accretor broadly reproduces the properties of ζ Ophiuchi, which has long been proposed to have accreted mass before being ejected as a runaway star when the companion exploded. We compare our accretor to models of single rotating stars and find that the later and stronger spin-up provided by mass accretion produces significant differences. Specifically, the core of the accretor retains higher spin at the end of the main sequence, and a convective layer develops that changes its density profile. Moreover, the surface of the accretor star is polluted by CNO-processed material donated by the companion. Our models show effects of mass accretion in binaries that are not captured in single rotating stellar models. This possibly impacts the further evolution (either in a binary or as single stars), the final collapse, and the resulting spin of the compact object.
Experimental mapping and assessment of ecosystem services based on multi-level landscape classification
Authors: Prodanova Hristina
Published: December 2021

The importance of the landscapes for the development of recreation and ecotourism is significant but very little studied. Usually, scientists use spatial units to map and assess the ecosystem services CORINE land cover or similar classifications. Traditional multi-level landscape classifications, very well-known and developed in the XXth century in Bulgaria, Russia, and other Eastern and Central European countries, could give valuable information for various indicators for ecosystem services assessment. From another hand, these classical landscape ecological maps are very little- known for the international scientific audience. We decided to conduct an experimental mapping and assessment of ecosystem services based on multi-level landscape classification. For this, we have chosen a case study area with hilly karst relief, which is part of the inner Predbalkan Region, located in North-Central Bulgaria. The site represents a scientific interest in terms of its transitional position between the Stara Planina Mountain and the Danube Plain and the presence of various anthropogenic changes. The study aimed to develop and test an original methodology for mapping and assessment of the capacity of the contemporary landscapes in the Strazhata syncline upland and Melovete hills to provide cultural ecosystem services – recreation and ecotourism. The results showed that 70% of the territory has medium or higher capacity, dominated mainly by karst areas with natural vegetation in protected sites.
Comparing species detection success between molecular markers in DNA metabarcoding of coastal macroinvertebrates
Authors: Leite Barbara R. , Vieira Pedro E. , Troncoso Jesús S. , Costa Filipe O.
Published: December 2021

DNA metabarcoding has great potential to improve marine biomonitoring programs by providing a rapid and accurate assessment of species composition in zoobenthic communities. However, some methodological improvements are still required, especially regarding failed detections, primers efficiency and incompleteness of databases. Here we assessed the efficiency of two different marker loci (COI and 18S) and three primer pairs in marine species detection through DNA metabarcoding of the macrozoobenthic communities colonizing three types of artificial substrates (slate, PVC and granite), sampled between 3 and 15 months of deployment. To accurately compare detection success between markers, we also compared the representativeness of the detected species in public databases and revised the reliability of the taxonomic assignments. Globally, we recorded extensive complementarity in the species detected by each marker, with 69% of the species exclusively detected by either 18S or COI. Individually, each of the three primer pairs recovered, at most, 52% of all species detected on the samples, showing also different abilities to amplify specific taxonomic groups. Most of the detected species have reliable reference sequences in their respective databases (82% for COI and 72% for 18S), meaning that when a species was detected by one marker and not by the other, it was most likely due to faulty amplification, and not by lack of matching sequences in the database. Overall, results showed the impact of marker and primer applied on species detection ability and indicated that, currently, if only a single marker or primer pair is employed in marine zoobenthos metabarcoding, a fair portion of the diversity may be overlooked.

Published: December 2021

DNA-based monitoring methods are potentially faster and cheaper compared to traditional morphological benthic identification. DNA metabarcoding involves various methodological choices which can introduce bias leading to a different outcome in biodiversity patterns. Therefore, it is important to harmonize DNA metabarcoding protocols to allow comparison across studies and this requires a good understanding of the effect of methodological choices on diversity estimates. This study investigated the impact of DNA and PCR replicates on the detection of macrobenthos species in locations with high, medium and low diversity. Our results show that two to three DNA replicates were needed in locations with a high and medium diversity to detect at least 80% of the species found in the six DNA replicates, while three to four replicates were needed in the location with low diversity. In contrast to general belief, larger body size or higher abundance of the species in a sample did not increase its detection prevalence among DNA replicates. However, rare species were less consistently detected across all DNA replicates of the location with high diversity compared to locations with less diversity. Our results further show that pooling of DNA replicates did not significantly alter diversity patterns, although a small number of rare species was lost. Finally, our results confirm high variation in species detection between PCR replicates, especially for the detection of rare species. These results contribute to create reliable, time and cost efficient metabarcoding protocols for the characterization of macrobenthos.
Self polarization and traveling wave in a model for cell crawling migration
Authors: Cucchi Alessandro , Mellet Antoine , Meunier Nicolas
Published: December 2021

In this paper, we prove the existence of traveling wave solutions for an incompressible Darcy's free boundary problem recently introduced in [6] to describe cell motility. This free boundary problem involves a nonlinear destabilizing term in the boundary condition which describes the active character of the cell cytoskeleton. By using two different methods, a constructive method via a graph analysis and a local bifurcation method, we prove that traveling wave solutions exist when the destabilizing term is strong enough.
ODE-RU: a dynamical system view on recurrent neural networks
Authors: Meng Pinchao , Wang Xinyu , Yin Weishi
Published: December 2021

The core of the demonstration of this paper is to interpret the forward propagation process of machine learning as a parameter estimation problem of nonlinear dynamical systems. This process is to establish a connection between the Recurrent Neural Network and the discrete differential equation, so as to construct a new network structure: ODE-RU. At the same time, under the inspiration of the theory of ordinary differential equations, we propose a new forward propagation mode. In a large number of simulations and experiments, the forward propagation not only shows the trainability of the new architecture, but also achieves a low training error on the basis of main-taining the stability of the network. For the problem requiring long-term memory, we specifically study the obstacle shape reconstruction problem using the backscattering far-field features data set, and demonstrate the effectiveness of the proposed architecture using the data set. The results show that the network can effectively reduce the sensitivity to small changes in the input feature. And the error generated by the ordinary differential equation cyclic unit network in inverting the shape and position of obstacles is less than $ 10^{-2} $.

Published: December 2021

In this paper, we propose an efficient method for some special solutions of the quaternion matrix equation $ AXB+CYD = E $. By integrating real representation of a quaternion matrix with $ \mathcal{H} $-representation, we investigate the minimal norm least squares solution of the previous quaternion matrix equation over different constrained matrices and obtain their expressions. In this way, we first apply $ \mathcal{H} $-representation to solve quaternion matrix equation with special structure, which not only broadens the application scope of $ \mathcal{H} $-representation, but further expands the research idea of solving quaternion matrix equation. The algorithms only include real operations. Consequently, it is very simple and convenient, and it can be applied to all kinds of quaternion matrix equation with similar problems. The numerical example is provided to illustrate the feasibility of our algorithms.
Data representation using robust nonnegative matrix factorization for edge computing
Authors: Yang Qing ,   School of Computer Engineering, Nanjing Institute of Technology, Hongjing Avenue, Nanjing, China, Chen Jun , Al-Nabhan Najla ,   Dept. Computer Science, King Saud University, Riyadh, KSA
Published: December 2021

As a popular data representation technique, Nonnegative matrix factorization (NMF) has been widely applied in edge computing, information retrieval and pattern recognition. Although it can learn parts-based data representations, existing NMF-based algorithms fail to integrate local and global structures of data to steer matrix factorization. Meanwhile, semi-supervised ones ignore the important role of instances from different classes in learning the representation. To solve such an issue, we propose a novel semi-supervised NMF approach via joint graph regularization and constraint propagation for edge computing, called robust constrained nonnegative matrix factorization (RCNMF), which learns robust discriminative representations by leveraging the power of both L2, 1-norm NMF and constraint propagation. Specifically, RCNMF explicitly exploits global and local structures of data to make latent representations of instances involved by the same class closer and those of instances involved by different classes farther. Furthermore, RCNMF introduces the L2, 1-norm cost function for addressing the problems of noise and outliers. Moreover, L2, 1-norm constraints on the factorial matrix are used to ensure the new representation sparse in rows. Finally, we exploit an optimization algorithm to solve the proposed framework. The convergence of such an optimization algorithm has been proven theoretically and empirically. Empirical experiments show that the proposed RCNMF is superior to other state-of-the-art algorithms.
Global Multi-Source Information Fusion Management and Deep Learning Optimization for Tourism
Authors: Yu Xue
Published: December 2021

The purpose is to solve the problems of sparse data information, low recommendation precision and recall rate and cold start of the current tourism personalized recommendation system. First, a context based personalized recommendation model (CPRM) is established by using the labeled-LDA (Labeled Latent Dirichlet Allocation) algorithm. The precision and recall of interest point recommendation are improved by mining the context information in unstructured text. Then, the interest point recommendation framework based on convolutional neural network (IPRC) is established. The semantic and emotional information in the comment text is extracted to identify user preferences, and the score of interest points in the target location is predicted combined with the influence factors of geographical location. Finally, real datasets are adopted to evaluate the recommendation precision and recall of the above two models and their performance of solving the cold start problem.

Qualitative Research Inquiry to Explore the Corporate Leaders in the Time of COVID-19
Authors: Eranda B. A. N.
Published: December 2021

The outbreak of COVID-19 has influenced the business organizations’ performance and behavior in numerous ways. Based on the pressing need to respond to this pandemic researchers have to play a significant role in uncovering the possibilities for business organizations to adapt to this uncertain situation. Therefore, it is important to pay attention on the corporate managers’ and entrepreneurs’ contextualized experiences and their meanings attributed to COVID-19 in order to mitigate failures and to learn to be sustained. This requires qualitative research which can be helpful to capturing the deeper understanding of lived realities of the corporate leaders who are affected by the pandemic. The qualitative researchers can adopt five types of approaches including narrative inquiry, phenomenology, grounded theory, ethnography, and case study to uncover these lived experiences of corporate respondents and to make sense of those experiences for the benefit of various stakeholders. Each of these five approaches to qualitative inquiry can be utilized for researching different facets of the corporate leaders at the time of pandemic. The in-person interactions need for qualitative inquiry to look into the corporate leaders’ lives is challenged by the social distancing generated by the new normal behavior. However, the evolving nature of the modern technology has ended this challenge with its novel initiatives.
Determinants of Financial Sustainability of the Microfinance Institutions in Sri Lanka
Authors: Perera H. S. C.
Published: December 2021

Today microfinance organizations are facing a challenge with how to balance poverty alleviation mission and sustainability. Hence, the importance of the sustainability of microfinance organizations goes beyond the poverty reduction mission. This research study was meant to determine the influential factors of financial sustainability in microfinance institutions in Sri Lanka. Existing two theories: Welfare Theory and Institutionalist theory were tested in MFIs in Sri Lanka with cause and effect relationship between variables, and the researcher adopted a cross-sectional research design with quantitative approach conducted in a field setting. Financial self-sufficiency is the dependent variable and twenty independent variables were used to test the determinant factors of sustainability. It was found that, the loan officer productivity, MFIs age, organization type, the yield on the gross loan portfolio, and profit margin have a positive and statistically strongly significance at 1% significant level. These factors profoundly affect the determination of the financial sustainability of MFIs in Sri Lanka. Further, the interest rate was positive with 5% statistically significant level, and active borrowers were positive with 10% in determining the financial sustainability of MFIs. Operating expenses ratio and capital structure negatively affected with 1% statistically significant level, where portfolio risk at 30 days affected negatively at 5% in determining the financial sustainability. Moreover, other factors: average loan size, the percentage of female borrowers, MFIs size, cost per borrower, number of MFIs products, lending methodology, geographic locations, write off ratio, risk coverage ratio and MFI regulations did not have a significant impact on financial sustainability in Sri Lanka.
The Moderating Impact of Team Tenure on Team Trust - Team Performance Relationship with Relevance to Executive Level Employees of Sri Lankan Tyre Manufacturing Industry
Authors: Rajapaksha B. P. , Nishanthi H. M.
Published: December 2021

Even though, many determinants of team performance are found in extended literature, team trust and the moderating effect of team tenure is little investigated in Sri Lankan context, and it has not been studied yet. Bridging the gap in this context, the current study assessed the moderating impact of team tenure on team trust and team performance relationship in Sri Lankan tyre manufacturing industry. The current study was conducted as a cross-sectional study among a sample of one hundred and ninety-two executive level employees selected from four major tyre manufacturing organizations following the stratified random sampling technique. Primary data were collected using a standard questionnaire distributed via Google form. The collected data were analysed with the support the SPSS employing correlation, regression, descriptive statistics and process matrix. It is found that team tenure does not moderate the relationship between team trust and team performance, and also founded that strong positive relationship between team trust and team performance. Moreover, team trust impact positively on team performance and team tenure does not impact team trust and team performance separately. It is recommended to tyre manufacturing organizations to facilitate more open communication and information sharing in order to improve executive level employees trust within teams, which in turn, will affect their team performance. Future researchers can use other variables like organizational support, team diversity, and personality as moderators of their study.
Factors Affecting Intention to use Mobile Money Service in Sri Lanka: Moderating Effect of Demographic Factors with reference to Western Province of Sri Lanka
Authors: Sanjeewa H. H. D. , Yatigammana M. R. K. N.
Published: December 2021

Mobile money service allows mobile users to perform financial transactions using their mobile phones which helps to decline the physical use of money. Therefore, the objective of the study was to identify the factors affecting intention to use mobile money service in Sri Lanka and the relationship between those identified factors and intention to use mobile money services. Further, the study is carried out to assess the moderating impact of demographic factors on the relationship between those factors and the intention to use mobile money. The data collection was carried out through a structured questionnaire from 400 randomly selected participants of Western province Sri Lanka. Usefulness, trust, risk, awareness, and knowledge are identified as the key factors affecting the intention to use mobile money service. There was a significant positive relationship between usefulness, trust, awareness, and knowledge with the intention to use mobile money while the risk was significantly negative. Further, the moderating impact of demographic factors on the above-identified five factors was assessed and it was noted that gender and age do not moderate the relationship between the above-identified five factors and user intention, but income level and job title moderate the relationship between above-identified factors and user intention. Based on the results of the study it is recommended that mobile telecom operators should take actions to increase usefulness, trust, awareness and knowledge while taking actions to decrease the risk factors involving in the service. Further, it is recommended to consider education level and working experience as moderating demographic factors of factors effecting on intention to use mobile money services.
Large Peritoneal Macrophages and Transitional Premonocytes Promote Survival during Abdominal Sepsis
Authors: Goswami Dinesh G , Rubio Andres J , Mata Jenna , Munoz Soraida , Gallegos Alejandra , Walker Wendy E
Published: December 2021

Monocytes and macrophages are early sentinels of infection. The peritoneum contains two resident populations: large and small peritoneal macrophages (LPMs and SPMs). While LPMs self-renew, circulating monocytes enter the peritoneum and differentiate into SPMs. We lack information on the dynamics of monocyte–macrophage trafficking during abdominal sepsis, reflecting an important knowledge gap. In this study, we characterize the presence of LPMs, SPMs, and monocytes in the peritoneum of mice following cecal ligation and puncture (CLP)–induced sepsis and sham surgery. LPMs rapidly disappeared from the peritoneum and were scarce at 18–66 h after CLP or sham surgery. By 14 d, LPMs returned for sham mice, but they remained scarce in CLP mice. Depletion of LPMs from the peritoneum of CD11b-DTR mice greatly increased animal mortality. These data imply that LPMs are critical for sepsis survival. Monocytes rapidly infiltrated the peritoneum and were abundant at 18–66 h after CLP or sham surgery. Surprisingly, SPMs only increased at 14 d post-CLP. Therefore, monocytes may defend hosts from acute sepsis mortality without generating SPMs. More monocytes were present in mice predicted to survive sepsis versus mice predicted to die. However, altering monocyte numbers via CCR2 deficiency or adoptive transfer did not significantly affect animal survival. We reasoned that animals destined to survive sepsis may exhibit a different monocyte phenotype, rather than merely enhanced numbers. Indeed, mice predicted to survive possessed more CD31+, CXCR4hi transitional premonocytes in their abdomen. Inhibition of CXCL12–CXCR4 signaling via AMD3100 exacerbated sepsis. These data imply that recruitment of transitional premonocytes to the abdomen promotes sepsis survival.

Published: December 2021

Asthma is a chronic and multifactorial disease which is known to result from environmental and genetic factors. Interleukin 1 receptor-like 1 (IL1RL1) is a receptor, which promotes inflammatory responses after binding to its ligand IL-33. Several studies have shown that IL1RL1 gene polymorphisms are related to susceptibility or protection to asthma. The objective of this study was to evaluate the association between two IL1RL1 single nucleotide polymorphisms (rs10208293 and rs1041973) and the risk of asthma in the Iranian population. We performed genotyping of the IL1RL1 SNPs in 126 adult asthmatics and 300 healthy controls using TaqMan genotyping assay. Moreover, total serum IgE level, eosinophil count, and skin prick test were accomplished. The results indicated that the AA genotype of rs10208293 was positively associated with asthma susceptibility (p=0.028). We did not find any association between rs1041973 and asthma. Overall, our findings indicate that rs10208293 has a positive association with asthma in the Iranian population.
Hidden positivity and a new approach to numerical computation of Hausdorff dimension: higher order methods
Authors: Falk Richard S. , Nussbaum Roger D.
Published: December 2021

In 2018, the authors developed a new approach to the computation of the Hausdorff dimension of the invariant set of an iterated function system or IFS. In this paper, we extend this approach to incorporate high order approximation methods. We again rely on the fact that we can associate to the IFS a parametrized family of positive, linear, Perron–Frobenius operators

L_s

, an idea known in varying degrees of generality for many years. Although

L_s

is not compact in the setting we consider, it possesses a strictly positive

C^m

eigenfunction

v_s

with eigenvalue

R(L_s)

for arbitrary

m

and all other points

z

in the spectrum of

L_s

satisfy

|z| \le b

for some constant

b < R(L_s)

. Under appropriate assumptions on the IFS, the Hausdorff dimension of the invariant set of the IFS is the value

s=s_*

for which

R(L_s) =1

. This eigenvalue problem is then approximated by a collocation method at the extended Chebyshev points of each subinterval using continuous piecewise polynomials of arbitrary degree

r

. Using an extension of the Perron theory of positive matrices to matrices that map a cone

K

to its interior and explicit a priori bounds on the derivatives of the strictly positive eigenfunction

v_s

, we give rigorous upper and lower bounds for the Hausdorff dimension

s_*

, and these bounds converge rapidly to

s_*

as the mesh size decreases and/or the polynomial degree increases.

An Elegant Method of Analysis for the BJT Amplifiers using Floating Admittance Matrix
Authors: Roy Sanjay Kumar , Sharma Kamal Kumar , Singh Brahmadeo Prasad
Published: December 2021

The Floating Admittance Matrix (FAM) is an elegant, neat, illustrative, and simplified technique for analyzing all configurations of the BJT amplifiers, starting with the maneuvering of the FAM of the phase-splitter circuit. The conventional analysis method requires a small-signal equivalent circuit, and then conventional tools, either KCL, KVL, or Thevenin, Norton, etc., are used for the analysis. The researcher has to guess which conventional tool suites better than the other for any particular circuit, whether active or passive. The proposed technique is equally ell useful for all circuits. In the FAM method, once the device matrix is known rest of the circuit can be embedded in it by inspection. The sum property of this matrix provides a check to know whether FAM has been written correctly to proceed further.

Published: December 2021

Honoring one's parents is the fifth of the ten commandments of God found in the book of Exodus. Over time, the attitude of respect for parents has decreased which is quite alarming. This is marked by the emergence of phenomena and cases that occur in neglected elderly and do not receive adequate services by their families and relatives around them. This study aims to provide an understanding and implications of the text output 20:12 so that readers have more respect for the elderly in the family and community environment. The method used is qualitative with a literature study approach related to the attitude of respect for the elderly contained in Exodus 20:12 to explain how to respect parents, especially the elderly. The results obtained are that Exodus 20:12 reflects the true respect for the elderly where it can be a guide for the welfare of the elderly in Indonesia, especially the Christian elderly. This respect is realized through the understanding that children as part of the family are not only supportive as a support system from the physical side but also spiritually.
¿Valores políticos o desempeño institucional? Un análisis de los determinantes de la confianza en las instituciones políticas en Perú
Authors: Benites Alexander
Published: December 2021

Diversos trabajos en la literatura califican la confianza en las instituciones como un elemento crucial para el adecuado funcionamiento del régimen democrático. A pesar de ello, el caso peruano presenta resultados alarmantes en lo que respecta a esta forma de confianza: una abrumadora mayoría de ciudadanos y ciudadanas desconfía de sus instituciones. En ese marco, este trabajo se pregunta, precisamente, por los determinantes de la confianza en las instituciones políticas en el Perú, recurriendo a los valores democráticos y al desempeño percibido sobre el funcionamiento de estos mismos objetos como posibles explicaciones. Los hallazgos de esta investigación muestran que el desempeño institucional juega un rol importante al momento de entender estas variaciones, con énfasis en el sentido de representación como indicador de calidad del proceso político. De forma similar, la idea de un funcionariado público ligado a la corrupción impacta negativamente en la confianza depositada en varias instituciones políticas; mientras que la percepción de un adecuado manejo de la economía nacional eleva los niveles de confianza, siendo estos aún mayores en el caso del presidente de la república. Por el lado de los valores democráticos, los resultados no son concluyentes: si bien el apoyo a la democracia impacta positivamente en la confianza, los indicadores de tolerancia política solo presentan impactos positivos cuando se trata de instituciones relacionadas directamente con el uso de la fuerza.
ANALYTICAL AND NUMERICAL INVESTIGATION OF ELASTIC STRESSES IN THERMOPLASTIC MATRIX COMPOSITE DISCS UNDER TEMPERATURE EFFECT
Authors: KAYIRAN Hüseyin Fırat
Published: December 2021

In this study, elastic stress analysis was performed on thermoplastic composite discs. The modulus of elasticity of thermoplastic composite discs is also different from each other. Our goal is to study elastic stretching. The field of application of primitive stresses caused by uneven temperature distribution in engineering is quite large. Under the parabolic temperature distribution of the disks, radial stresses formed on the inner and outer parts of the disks were calculated by assuming that the modulus of elasticity does not change with temperature at temperatures of 30 °C, 60 °C, 90 °C, 120 °C on the inner and outer surfaces of the disk. During the study, analytical and numerical analysis was performed using a computer program and mathematically modeled ANSYS programs. Both methods give similar results. In other words, the differences analytical and numerical results can be ignored. At the end of this study, it was determined that the radial and tangential stress values were higher at high temperatures than at low temperatures. It has been established that tangential stresses are much larger than radial stresses. The purpose of this article is to study the behavior of the thermal load on two different thermoplastic disks.

Basti is said to be the best therapy for pacifying aggravated Vata Dosha. It is considered as Ardha Chikitsa due to the capacity to cure diseases of either Abhyantara, Bahya or Madhyama Roga Marga when used judiciously. It is broadly classified into Niruha, Anuvasana and Uttara Basti Anuvasana Basti believed to nourish the body and increase Bala (strength) and Varna (complexion). Matra Basti is a type of Anuvasana Basti in which the Sneha is administered in the lowest dosage. Gridhrasi is one among Vataja Nanatmaja Vikara characterised by Stabdhata (stiffness), Vedana (pain), Toda (pricking sensation) in the lumbar region radiating to the lower limb. Gridhrasi is of two types viz Vataja and Vata Kaphaja Gridhrasi. Vataja Gridhrasi is characterized by severe pain whereas, Vata Kaphaja Gridhrasi has symptoms viz Tandra (drowsiness), Gaurava (heaviness of body) and Aruchi (ano- rexia). Bala Taila contains Madhura Rasa, Snigdha, Vatahara, Balya, Brumhana properties. Sahachara Taila contains Madhura Tikta Rasa, Ushna Veerya and Vata-Kaphahara properties. This study was undertaken to com- pare the efficacy of Matra Basti with Bala Taila and Sahachara Taila in the management of Gridhrasi to ascer- tain a better modality. Statistical analysis showed that both groups showed good improvement in various parame- ters of Gridhrasi. When compared between the groups it revealed that there was not statistically difference except in S Lanss Pain Score (p<0.05). Hence it can be concluded that both Bala Taila Matra Basti and Sahachara TailaMatra Basti may be practiced in treating patients with Gridhrasi (Sciatica) to reduce both signs and symptoms successfully.

Tennis elbow is a condition in which there is pain on the lateral epicondyle. It is a type of repetitive strain injury due to overexertion of the common extensor tendon (snayu), micro-traumas, or its failed healing. Tennis elbow may be correlated with snāyugata vāta in kūrpara sandhi (elbow) which has symptoms of pain, stiffness and restriction of movements. Ācārya Suśruta has mentioned snigdha agnikarma (thermal cautery) in the management of snayugata vata. 16 participants satisfying the diagnostic, inclusion and exclusion criteria were selected for the study. Agnikarma using honey (madhu) was done on the 1st and 8th days. Clinical assessments were done on the 1st, 8th, 15th, 22nd, 29th days. On statistical analysis, it was found that agnikarma using madhu shows 68.22% of effect in the management of tennis elbow.

Nowadays due to changing lifestyle, lack of physical activity and long sitting postures lead to a disease called Gridhrasi. Symptoms of Gridhrasi closely resemble the clinical features of Sciatica. Sciatica is a severely painful condition where the sciatic nerve of one or both legs is involved. This study was undertaken to evaluate the clinical efficacy of Aabhadi Churna along with Pathya Aahara and Vihara in Gridhrasi with special reference to Sciatica. The study was conducted on 60 patients who fulfilled the diagnostic and inclusive criteria of sciatica. The clinical assessment was based on subjective parameters (Ruka, Stambha, Toda, Spandana) and objective parameters (Straight leg raising test, standing time and walking time). The subjective and objective parameters before and after treatment were analyzed by using the student "t" test. The t-test results were highly significant for both the groups when the therapy effect was compared before and after the treatment. The inter-group comparison showed that the Group-B treatment method where 84% of patients showed moderate to maximum improvement method was better when compared to Group-A where this percentage was 67% only.

Što je sve film?
Authors: Turković Hrvoje
Published: December 2021

U radu se sažeto daju jezgrene teorijske odrednice filma, odnosno audiovizualnog djela i područja, one koje su relevantnim orijentirima pogodne za empirijska istraživanja. Prvo, filmsko djelo je ograničena tvarna pojava u ljudskom okružju, njome se može baratati i prema njoj nekako životno odnositi. Drugo, posrijedi je tehnološki temeljena izrađevina, koja je uvjetovana tehnologijom i uvjetuje popratni razvoj i razradu tehnike za svoje potrebe. Treće, film se izrađuje kako bi potakao i razrađivao reakcije u ljudi, i to mu je temeljna uporabna svrha. Četvrto, tehnološko vladanje izrađivanjem omogućuje kontrolirano izrađivačko modeliranje gledateljevih doživljaja, pa je film, utoliko, epistemološkomodelotvornom izrađevinom. Modeliranje podrazumijeva dva tipa komunikacijskog sudjelovanja: izrađivači adresiraju potencijalne ili stvarne gledatelje, ali i gledatelji međusobno (kao publika) dijele iskustva gledanja činjenicom da su izloženi filmskoj izrađevini, njezinim modelotvornim poticajima. Peto, sve je to prethodno ujedno i društveno-kulturni čin, film crpi iz okružujuće kulture i njezinim je čimbenikom. Šesto, film je u svim svojim aspektima društven i utoliko je neizbježno društveno organizacijski i institucijski podržan.
