Problems of Cultural and Chronological Identification of the Ust-Ilir Burial Ground (Southern Angara Region)
Authors:   Irkutsk State University, Berdnikov I. M. , Sokolova N. B. ,   Irkutsk State University
Published: May 2022

The search for the Middle Neolithic burial complexes in Baikal-Yenisei Siberia is one of the most important fields of modern regional research. It is directly related to the problem of the so-called hiatus, which is characterized by the absence of dated burials for several hundred years between the Early and Late Neolithic in the range of ~7–5.5 ka cal BP (or ~6.6–6 ka cal BP to updated data). We see the greatest prospects at this stage of research in identifying the burials of hunter-gatherers who owned the technique of making Ust-Belaya pottery, so the connection of this ceramic type with some burials is already quite clear. This article proposes a new view on the cultural and chronological affiliation of the Ust-Ilir burial ground, which was discovered in 1990 at the mouth of the Ilir River, the left tributary of the Iya River (Southern Angara region). It is distinguished by the originality of the mortuary rite and inventory and stands out against the background of the known Neolithic burial complexes in Baikal-Yenisei Siberia. In the grave, partially destroyed by the Bratsk Reservoir, the remains of three people, fire traces and “ocher” spots (powdered red mineral pigment) were found. During the excavation of the burial, along with various tools, bone needle cases with carved ornaments, pendants from deer teeth, and bone pendants that imitate the latter in shape, unique objects of art were found - miniature bone sculptures with images of waterfowl. In addition, on the beach where the burial was discovered, exhibited finds were collected, including stone and bone tools, as well as fragments of ceramics of the Ust-Belaya type, which most likely belong to this complex. As a result of the analysis of the elements of mortuary rite and inventory of the Ust-Ilir burial ground, its similarity to some Neolithic burials of Krasnoyarsk, the Northern and Southern Angara region, whose cultural and chronological affiliation has not yet been clearly defined, has been established. The closest to Ust-Ilir is the burial complex discovered in 1959 in Krasnoyarsk near the Gremyachii Klyuch stream, in the materials of which there are similar artifacts with images of waterfowl and needle cases with an ornament. We recently obtained a radiocarbon date for this complex from a deer bone sample (from the inventory), which shows its age at 5280±25 BP (6182–5943 cal BP). Given the above facts, the Ust-Ilir burial ground can be synchronous with the Gremyachii Klyuch burial. These complexes, as well as burials close to them from other areas of Baikal-Yenisei Siberia, with a high degree of probability could have belonged to hunter-gatherers who own the Ust-Belaya pottery tradition and inhabited the region in the Middle Neolithic.

This article presents Ust-Belaya ceramics of the Ust-Belaya site from the funds of the Muravyov-Amursky Irkutsk Regional Museum of Local History. The multilayered site Ust-Belaya is located 110 km northwest of Irkutsk at the Belaya River mouth (left tributary of the Angara). The considered Ust-Belaya ceramics belongs to the finds from the excavations of 1958–1964. The collection includes 1331 fragments from at least 60 pots. The vessels have a simple closed, rarely open shape and a rounded bottom. The ornament could be located both the upper part of the vessel and cover it entirely. Vessels ornamented with horizontal straight lines predominate. In three cases they are complemented by zigzag lines. The rim on the outer side or on both sides is decorated with oblique impressions of a comb stamp, rarely smooth or other varieties of serrated tools. Almost all vessels in the rim area have a line of rounded pits. The main part of the ornamental composition is represented by lines of a receding scapula or rows of impressions of comb, larval and other types of toothed stamp (rarely smooth), which are set close, separately or using the technique of retreat. Signs of making, recorded on ceramics during the study, allow us to identify several features in the production of Ust-Belaya type ceramics. The vessels were formed by the method of zonal patchwork modeling, partially or almost completely on a base form, which could be another vessel. In the production of vessels, they were knocked out with a smooth mallet, achieving dense and thin walls. Upon completion of the modeling, a rim was formed using an additional structural element such as a conditional tape or funiculus. Then the vessel was ornamented, and the walls were smoothed or rubbed from the inside. Since the finds of 1958–1964 deposited in a mixed compression layer, which complicates dating. In 2017–2018 at the Ust-Belaya site, located on the middle floodplain, Ust-Belaya pottery was recorded in a clear stratigraphic position. Based on bones from the layer, dates were obtained with a range of 6730–6306 cal BP. Also, according to one Ust-Belaya vessel from other excavations of Ust-Belaya in 1957, a date was obtained from carbonized organic residues (foodcrusts) from the inner surface with a value of 6977–6800 cal BP. By analogy with these assemblages, the age of the collection of Ust- Belaya ceramics presented by us is tentatively determined in the range of 6977–6306 cal BP.
Zoomorphic Images of Diseases Among the Turkic-Mongolian Peoples of Siberia
Authors:   Institute for Mongolian, Buddhist and Tibetan Studies SB RAS, Sodnompilova M. M.
Published: May 2022

The study of the causes of a wide range of diseases in the traditional worldview of the Turko-Mongolian peoples revealed a wide range of “culprits” that cause diseases, the nature of which people could not explain. First, these are infectious diseases, mental illnesses, diseases of internal organs and many others. The images of supernatural forces that cause diseases are well known – these are deities and spirits of all spheres of the mythological universe, heavenly bodies, winds, fogs. But, if the images of the “owners” of diseases are well known, then the question of what kind of diseases themselves could have remains unresolved. Information about how people in traditional society representes each specific disease is very scarce. Nevertheless, they exist, and their study is of great interest, since these ideas contribute to the understanding of folk methods of healing, measures that protect against diseases. Thus, the article aims to identify popular ideas about the appearance of diseases, their causes, methods of their treatment and prevention in the traditional culture of the Turko- Mongolian peoples of Siberia. Known information regarding the images of some common diseases shows that they were mainly images of a worm, snake, hairspring. These images arose under the influence of ideas about reptiles and amphibians, as well as parasites, which the population of Siberia suffered everywhere in the 19th century. Attention is drawn to the image of diseases affecting the joints and bones. These diseases were represented by the spirit of a dog killed by a man who took revenge on his killer by gnawing his bones and causing him excruciating pain. This image is most likely inspired by the nature of the painful sensations caused by rheumatism, arthrosis, and other diseases of the musculoskeletal system. In some situations, specific images of diseases justified the methods of healing, for example, the use of ointments prepared from worms. Part of the healing techniques was aimed at expelling the disease from the patient's body, and in this case, they used to mean that frightened the spirit of the disease, or harmed him - fire, poisonous mixtures. At the same time, rational methods of treatment were also used in folk medicine. The use of hot medicinal baths, poultices from medicinal plants in the treatment of diseases of the musculoskeletal system, certainly reflects the positive experience of the population of Siberia, accumulated over many centuries. Rational also seems to be the classification of household products and clothing made from natural materials according to useful and harmful properties.

Published: May 2022

The article presents arguments for necessity to determine the attitude of education actors to a new distant form of learning. The results of the study of semantic assessment of distant learning by students and schoolchildren have been presented. The sematic differential has been used to analyze the data obtained. The semantics of distant learning identified by its actors on the basis of the categories of “comfort”, “intellectual efficiency”, “workload”, and “externality”. There are differences in the semantic assessment of distant learning by students and schoolchildren. Students gave much lower estimates to distance learning by intellectual efficiency parameter, while estimating the workload parameter higher. Schoolgirls gave negative assessment to distance learning by all parameters. The findings indicate that there is a need to arrange personalized distance learning.

Published: May 2022

The article presents the analysis of theoretical and methodological aspects of the study of symbolization and symbolical resources of a personality. The author has provided the analysis of the essence of symbolical processes and their role in socio-psychological adaptation of a subject. In a psychological context, the symbolization process is aimed at supporting and facilitating the interaction of a subject with other people, inner self, and the subjective world. Symbolization processes generate and inspire meanings of life, open up new opportunities for a person in the way not thought of before, which expand his or her inner world and spiritual experience, increase the range of variability of actions and emotional manifestations, remove stereotypes of behavior and activities, provide an opportunity for a more harmonic interaction with other people as well as the world of culture, science, and creativity.

species
Authors: Tanimola A.R. , Otegbayo B.O. , Akinoso R.
Published: May 2022

This study investigated the morphology of the granules, physicochemical and pasting
properties of fifty-five starches of Dioscorea rotundata and Dioscorea alata varieties. The
granules sizes and shapes, swelling power, solubility, water absorption capacity, water
binding capacity, pH, titratable acidity and pasting properties were evaluated by standard
procedures. The result of the granule morphology showed that both varieties were in the
range of large starch granules, however, D. rotundata varieties (32.40 – 57.01 µm by
22.38 – 35.70 µm) were significantly larger than those of D. alata varieties (18.33 - 48.91
µm by 13.38 – 33.10 µm). The granule sizes were observed to have a significant effect on
the physicochemical properties, as D. rotundata species were significantly higher in
swelling power (7.50 g/g) and lower in water absorption (66.20%) and water-binding
capacities (57.16%). Also, D. rotundata species showed significantly higher peak
viscosity (518.50 RVU), holding strength (260.95 RVU) and breakdown viscosity (257.54
RVU), all contributing to their potential industrial uses. The present characterisation of
fifty-five varieties of Dioscorea species germplasm in Nigeria adds to the database on
physicochemical properties of yams, providing relevant information for both food and non
-food uses.

Published: May 2022

Starch nanoparticles from breadfruit (Artocarpus altilis) have been prepared using
nanoprecipitation. The study aimed to investigate the performance of dropwise and direct
mixing of ethanol as a non-solvent in the presence of and without surfactant (Tween 80)
into breadfruit suspension during nanoprecipitation. The resulting breadfruit starch
nanoparticles were evaluated for particle size and shape by particle size analysis,
transmission electron microscopy (TEM), and scanning electron microscopy (SEM),
crystal pattern by X-ray diffraction (XRD), and functional group by FTIR
spectrophotometer. It was observed that performing the dropwise mixing technique
without Tween 80 produced particles in the nanometer scale (175 nm), with uniform size
distribution (18-459 nm), a porous surface, and an amorphous phase (single XRD peak at
19o
). These breadfruit starch nanoparticles pave the way for incorporating starch products
into a wide array of industry-application.
Physical properties and sensory acceptability of gum arabic-coated cherry
tomato fruit during storage
Authors: Sumonsiri N. , Charoensantisuk K. , Paonoi N. , Kittayangkul P.
Published: May 2022

Cherry tomato is a small climacteric fruit with a short shelf life ranging from 5 to 7 days
due to postharvest diseases, accelerated ripening, and senescence, all of which cause
losses in quantity and quality. An edible coating can be used to extend the shelf life of
fresh fruits by acting as a barrier against the transfer of oxygen, carbon dioxide, moisture,
aroma, and volatile compounds during storage. This research focused on the effect of gum
arabic on the physical properties and sensory acceptability of cherry tomatoes during cold
storage at 13 and 25˚C. Weight loss, firmness, and colour (L*, C*, and h*) of control and
coated cherry tomato fruits were measured during storage at 13 and 25˚C, as well as the
sensory acceptability of samples after 16 days at 13˚C. Coating cherry tomatoes with gum
arabic (2-5% w/w) significantly decreased weight loss while maintaining firmness and
colour during storage. In sensory evaluation, the coated samples obtained the same or
significantly higher acceptability scores than the control samples, especially in
appearance, texture, and overall acceptance

Published: May 2022

Whey protein isolate (WPI) and whey protein hydrolysate (WPH) contains more protein
than whey protein concentrate. However, to achieve a better taste, most commercial
products mix WPI and WPH with whey protein concentrate (WPC). This study aimed to
compare postprandial blood amino acids following ingestion of three beverages: WPImixed with WPC (WPI-mixed), WPH-mixed with WPI (WPH-mixed), and placebo. A
total of ten healthy men aged between 18 and 30, who regularly engaged in exercise
training, were recruited as participants. They each received 350 mL of each beverage on
separate days and 6-day apart. Concentrations of plasma essential amino acids (EAA),
branched-chain amino acids (BCAA), and leucine (Leu) were measured in blood samples
taken from participants every 15 mins for 2 hrs. Plasma concentrations of EAA, BCAA,
and Leu increased after ingestion of the WPI-mixed and WPH-mixed beverages versus the
placebo beverage (P<0.05). Plasma EAA did not differ between WPI- mixed and WPmixed trials. In contrast, plasma concentrations of BCAA after WPI-mixed were higher
than after WPH-mixed at 30 mins. The same was observed for Leu at 30 and 75 mins after
ingestion. The higher plasma BCAA and Leu in the WPI-mixed trial versus the WPHmixed trial may have been due to the presence of short-chain peptides, as bioactive
peptides, in WPH-mixed, which were absorbed. In conclusion, there was no difference in
plasma EAA, but plasma concentrations of leucine and BCAA were higher in the WPImixed trial than WPH-mixed trial. Therefore, future research should investigate bioactive
peptides along with plasma amino acids.
Exploring triosephosphate isomerase diversity in photosynthetic organisms
Authors:   , Jones Gareth
Published: May 2022

Triosephosphate isomerase (TPI) is one of the most well characterised enzymes in the BRaunschweig ENzyme DAtabase (BRENDA). TPI is widely investigated in the context of glycolysis/gluconeogenesis, however, in photosynthetic organisms TPI is also involved in the regeneration phase of the Calvin-Benson-Bassham (CBB) cycle. Cyanobacteria possess a single TPI involved in both pathways, however, plants and many algae possess two TPI isoforms, a cytoplasmic isoform and a chloroplastic isoform, that are involved in glycolysis/gluconeogenesis and the CBB cycle respectively. This TPI organisation provides an opportunity to investigate how photosynthesis and adaptation to the chloroplast has shaped the evolution of TPI. For instance, the TPI inhibitor, 2-phosphoglycolate (2PG) is produced in the chloroplast due to oxygenation activity of ribulose 1,5 bisphosphate carboxylase/oxygenase (rubisco).

This project gains insight into TPI evolution by investigating the TPIs of three photosynthetic, and one derived non-photosynthetic, species. The organisms investigated were; the model cyanobacterium Synechocystis sp. PCC6803, the model plant Arabidopsis thaliana, the red alga Porphyra umbilicalis, and the non-photosynthetic parasitic plant Cuscuta australis. The TPIs from these organisms were characterised using structure/function and kinetic paradigms.

The characterisation of Synechocystis and A. thaliana TPIs were used to establish workflow and to generate a baseline to compare the underexplored TPIs of C. australis and P. umbilicalis.

The C. australis TPIs were investigated in the context of relaxed purifying selection resulting from adaptation of C. australis to parasitism and subsequent loss of photosynthesis. I reported that relaxed purifying selection has eroded the activity of C. australis TPIs compared to A. thalaina orthologues. Additionally, the structures of both C. australis cytoplasmic and chloroplast TPIs were solved by X-ray crystallography to identify where in the structure relaxed purifying selection has acted.

The P. umbilicalis TPIs were investigated in the context of 2PG inhibition as the rubisco of red alga are infamous for their low rate of rubisco oxygenation activity. I have demonstrated that there is no difference in 2PG inhibition between P. umbilicalis and A. thaliana TPIs. However, unexpectedly I identified that the chloroplast TPI of P. umbilicalis is exquisitely sensitive to oxidation.
Learning From High-Cardinality Categorical Features in Deep Neural Networks
Authors: Arat Mustafa Murat
Published: May 2022

Some machine learning algorithms expect the input variables and the output variables to be numeric. Therefore, in an early stage of modelling, feature engineering is required when categorical variables present in the dataset. As a result, we must encode those attributes into an appropriate feature vector. However, categorical variables having more than 100 unique values are considered to be high-cardinality and there exists no straightforward methods to handle them. Besides, the majority of the work on categorical variable encoding in the literature assumes that the categories is limited, known beforehand, and made up of mutually-exclusive elements, inde-pendently from the data, which is not necessarily true for real-world applications. Feature engineering typically practices to tackle the high cardinality issues with data-cleaning techniques which they are time-consuming and often needs human intervention and domain expertise which are major costs in data science projects The most common methods of transform categorical variables is one-hot encoding and target encoding. To address the issue of encoding categorical variables in environments with a high cardinality, we also seek a general-purpose approach for statistical analysis of categorical entries that is capable of handling a very large number of catego-ries, while avoiding computational and statistical difficulties. Our proposed approach is low dimensional; thus, it is very efficient in processing time and memory, it can be computed in an online learning setting. Even though for this paper, we opt to utilize it in the input layer, dictionaries are typically architecture-independent and may be moved between different architectures or layers.

It is of great importance to determine the antioxidant properties of plants, especially those used for food, pharmacology and medicinal purposes. Stachys thirkei C.Koch belonging to Lamiaceae family is used as a medicinal aromatic plant in Turkey. The present study was carried out to investigate the total phenolic contents, antioxidant activity and bioaccessibility of S. thirkei C.Koch. The total phenolic content (TPC) was evaluated by Folin-Ciocalteu colorimetric procedure and antioxidant activity determine four distinctive methods (ABTS•+, CUPRAC, DPPH• and FRAP). According to the results, the levels of hydrolysable phenolics (1538.99±4.57 mg of GAE/100g) approximately three and a half fold higher than extractable phenolics (422.96±4.70 mg of GAE/100g). The TPC of S. thirkei C.Koch was determined to be 1961.95±4.46 mg of GAE/100g. On the other hand, the bioaccessible fractions and phenolic bioaccessibility of S. thirkei C.Koch were found to be 1766.72±2.96 μmol Trolox/g and 90.05±1.50%, respectively. At the same time, the antioxidative bioaccessibility of S. thirkei was found to be higher in FRAP method (1164.29 μmol Trolox/g) and also the bioaccessibility (%) of S. thirkei C.Koch was found to be higher in CUPRAC method (93.41%). Present study is the first report to investigate the antioxidant effect and bioaccessibility of the extracts from S. thirkei C.Koch. The results of the present study can be strong scientific proof to use this plant as a beneficial source of antioxidant referments and the studies can be further extended to investigate whether they exhibit similar activities in in vivo systems.
Orbital Period Changes of Selected Two Semi-Deteached Binaries
Authors: Yıldırım Muhammed Faruk
Published: May 2022

Since the data obtained from satellite data are very sensitive, the minima times of the target systems have obtained from Kepler (K2) and TESS observations. A total of 14 minima times were obtained from Kepler (K2) data for the AF Gem system and 11 minima times in two different sectors from the TESS data for the RY Gem system. In this study, orbital period behaviors of semi-detached binaries (SDBs) AF Gem and RY Gem systems have investigated, together with minima times obtained from literature and satellite data. It has been observed that the orbital periods of AF Gem and RY Gem decrease. The period change rates of AF Gem and RY Gem systems are determined as -4.1×10-8 and -6.5×10-6 day/ year. The magnetic activity of the cooler components of the systems may be the reason for the periods decrease, and therefore the mass loss rates of the systems have calculated. For AF Gem and RY Gem, mass loss rate was found to be -4.4×10-8 M⊙/year and -8.2×10-7 M⊙/year, respectively. In the O-C graph of AF Gem, sinüsoidal variations also exist. Sinusoidal change may be demonstrated as being the result of a light time effect (LITE) via a tertiary body around the eclipsing pair. The minimum mass of probable third star around AF Gem has found to be 0.24 M⊙.

Approximate solutions of the Fourth-Order Eigenvalue Problem
Authors: Arslan Derya
Published: May 2022

In this paper, the differential transformation (DTM) and the Adomian decomposition (ADM) methods are proposed for solving fourth order eigenvalue problem. This fourth order eigenvalue problem has nonstrongly regular boundary conditions. This the fourth order problem has been examined for p(t) = t, B = 0, a = 0,01 where p(t) ≠ 0 is a complex valued and a ≠ 0 The differential transformation and the Adomian decomposition methods are briefly described. An approximate solution is obtained by performing seven iterations with the Adomian decomposition method. The same number of iterations have been made in the differential transformation method. The approximation results obtained by both methods have been compared with each other. These data have been presented in table. The ADM and the DTM approximation solutions have been shown by plotting in Figure 1. Here, the approaches obtained by using the two methods are found to be in high agreement. Consequently, highly accurate approximate solutions of fourth order eigenvalue problem are obtained. Such good results also revealed that the Adomian decomposition and the differential transformation methods are fast, economical and motivating. The exact solution of the fourth order eigenvalue problem for nonstrongly regular can not be found in the literature. Therefore, this study will give an important idea to determine approximate solution behavior of this fourth order problem.
MANIPURI NATA SANKIRTANA
Authors: Singh M. Thoiba
Published: May 2022

Nata-Sankirtana of Manipur is considered as Purvaranga and Mahayajna in Vaisnavite culture of Manipur. Yajna means all acts performed for the satisfaction of paramatama, pritilok, devalok and for those who have sanskar (purification), for the beings and for keeping the cycle of nature, for the goodness (Singh M. T., NATASANKIRTANA AS A MAHAYAJNA, 2017). Not only these, but it also denotes mantra performed by the believers of Sanatana Dharma, Dravya, Shraddha and different Shatkarmas. For centuries, Nata-Sankirtana has been performing as an important practice, as a Gandharva Vidya, Purvaranga, and a MahaYajna in the society of Manipuri GouriyaVaishnavites. NataSankirtana became a part and parcel of Manipuri Vaishnava community’s socio-religious activities and prosperity. (Singh M. T., Manipuri Nata Sankirtana: Perspectives and Prospects, 2015) In ShrimadBhagavata, the only merit in Kali yuga is Harinam Sankirtana in which a person can reach his end and attain moksha. We have been worshipping him in one form or the other. We worship him with the help of drum or with song and dance and it is known as Gandharbam. The different religions of Prachin Bharat i.e. Sheiba, Shakta, Boudha, Jain, etc. have devised ways to worship the Istadevata starting with Sankirtana. The religious sect of Sanatana searches different means to get the almighty. In Satya Yuga, Dhyan was the only means to get blessing of God, Yajna for Treta, Puja for Dwapur and Hari Sankirtana for Kali are believed to be sure. It is also believed that the end of Dhyan, Yajna, and Puja is equal to the observance of Hari Nam Sankirtana. Thus, chanting the name of Shree Krishna is the only means in Kali Yuga. This chanting of Mahamantra will enable the soul to free from the sansarmaya and connect with Godhead. This paper tried to understand the Nata-Sankirtana and its role in Manipuri Society, to know the formalities for performing Manipuri Nata-Sankirtana and to identify the different parts required for doing a whole Nata-Sankirtana performance.

Tabla is the most versatile among percussion instruments today. The challenge that it meets till date is the recognition that Tabla has in terms of a Solo instrument. Although acclaimed worldwide for its versatility, yet the role of Tabla as a Solo instrument remains undefined at large. The tabla player today occupies a decent place on stage during accompaniment and exhibits the art, at times with his repertoire, especially when he accompanies to instrumental music. The rich repertoire of Tabla, which is learnt through life finds its expression only through solo performances, but this is confined only to the elite artists. There is no denial to the fact that Tabla is basically an accompanying instrument. Accompaniment is a beautiful art and every tabla artist should be an able accompanist. In fact, the art of accompaniment does need a better craftsmanship and a greater aesthetic sense than the art of tabla solo presentation. Given to these facts, the repertoire of tabla finds complete expression only during a solo performance. The collection of compositions of tabla from the masters of yesteryears is huge, and how many tabla players are able to put it across the listeners, even a meagre part of what they have learnt in the lineage? And the truth is that the Tabla is the primary accompanying instrument in North Indian classical, fusion and light music today.  This is the struggle in its versatility.  The music fraternity and the organizers need to ponder over this and improve their endeavors to promote Tabla more, as a solo instrument also.
RELIGIOUS SYMBOLISM IN THE WORKS OF GRAPHIC ARTIST-NARENDRA SRIVASTAVA
Authors: Thakur Meenakshi
Published: May 2022

Religious symbolism implies the use of unique symbols by a particular religion, that describe anything pertaining to its culture and psyche, including archetypes, events, natural phenomena or even the art that evolved in that land over a period of time. All religions of the world, irrespective of how ancient or modern they are, use symbols to help create a resonant ethos, which in turn, reflects the moral values, teachings and culture of that society. The concept of religious symbolism is very ancient and may well have had its roots from the start of mankind itself. This can be seen in the series of paintings with the word ‘DHARMA’ painted in 1984, done basically for calendar, depicting six great religions of world Hinduism, Buddhism, Christianity, Islam, Confucianism, and Judaism by renowned graphic designer, eminent artist, and art educationist, Narendra Srivastava. By seeing these drawings it seems that artist must be highly religious which is not true because he had used the word graphically only. He did it for his pleasure of creating something new out of it, which makes his artworks very creative. These paintings do have some religious symbolism in it, which the artist had graphically depicted in a very innovative and impressive style.
GANGAVATARAN THEME ON CHAMBA RUMAL
Authors: Kaur Jasminder
Published: May 2022

The needle art or embroidery was the famous time pass of Indian woman folk. Many of these home-grown techniques have taken a place in the larger canvass of Indian art. Chamba rumal of Himachal Pradesh is one of them. It is narrative theme & technique, and commands a special place in the Indian embroidery world. Chamba rumal is embroidered on off white cotton cloth with untwisted silk threads. Although we find two styles of embroidery in the Chamba valley, the classical one is the style famous in the art world with the name of Chamba Rumal. The classical style of the embroidery was developed under the patronage of Royal families of the Himachal Pradesh. This embroidery style and Pahadi painting developed parallel to each other. This is the reason that the scenes depicted on these Rumals have striking similarity with Pahadi paintings. There are many examples showing the alikeness and similar theme between Chamba rumals and Pahadi Paintings. A Chamba rumal with Gangavartaran theme alike to the Pahadi painting is in the collection of Bharat Kala Bhavan museum in Banaras Hindu University. This has the depiction of the famous story of Holy river Ganga’s flow from heaven to the earth on the request of King Bhagirath who did much of penance & austerities to bring Ganga on earth to get salvation for his forefathers.

Published: May 2022

The present study is designed to diagnose the giardiasis from cattle and patients with diarrhea arrivals to Maternity and Childhood Teaching Hospital and General Education Hospital in Al-Qadisiya Governorate by using direct wet smear method as well as knowledge of the rate of prevalence of giardiasis in Al- Diwaniyah province, and study the effect of age, sex and nature of residence in the proportions of infection and investigate the genotypes of Giardia lamblia from human and animal feces ,100 samples were collected (50 stool samples of human and 50 feces samples of cattle). In human, the result showed that the infection rate was 54% (27). The age group of 2-4 years showed the highest rate of infection (40.7%), while children aged 8-10 years showed the lowest rate of infection (3.7%). The results showed that 16 (59.2%) out of 27 and 11 (47.8%) out of 23 of males and females were positive respectively, so the rate of females cases were higher than males , with non-significant differences at p > 0.05 . It was found that the majority of cases (66.6%) were from rural areas. DNA was extracted from positive samples (25 samples of human and 25 samples of cattle ) then after amplified using primers for triosephosphateisomerase (tpi) gene that specific for genotyping A and B, the result showed that 17(68%) were genotype B and 3(12%) were genotype A, while 5(20%) were both genotype A and B. However in cattle, the result showed that the infection rate was 70% (35). The age group of <6 month showed the highest rate of infection was (45.7%), while calves aged 6month-1year showed the lowest rate of infection was (22.8%). The results showed the number of positive cases according to the sex were 14 (40%) and 21(60%) in male and female respectively that showed higher positively of females when compared with males with significant difference at p<0.05. The result of distribution of genotypes of Giardia lamblia in cattle showed that 16(64%) were genotype B and 5(20%) were genotype A while 4(16%) were both genotype A and B.

A young renal transplant recipient received living kidney from his father; the Centers for Disease Control and Prevention (CDC) cross match was all negative. He had oliguria 5 hours after transplant with fever and neutrophil leukocytosis. Doppler ultrasonogram revealed increased cortical echo with increased Resistive Index suggesting acute rejection or acute tubular necrosis. Renal transplant biopsy revealed acute T cell mediated rejection (acute TCMR) Grade IIA. Trough level of Tacrolimus blood level done on Day 5 was very low; therefore, Tacrolimus dose was increased. Therapeutic level achieved after giving 6 mg twice a day with addition of erythromycin. Escalating antibiotics, increasing steroids and Tacrolimus dose saved the transplant kidney.

In Montenegro, a herpetofaunal species richness has not translated into detailed ecological studies. An example is the marsh frog, one of the most common amphibians in Montenegro, which has insufficient information on its population and ecological structure, including feeding ecology. This study compared the morphological and ecological (diet, type of growth and condition) profiles of marsh frogs from two artificial lakes (Krupac and Slano) located in the central region of Montenegro. The comparison of morphometric ratios between localities revealed that two indices show the weak discrimination between populations. The dietary composition of the marsh frog, from studied artificial lakes, is similar to that of populations from natural habitats. Obtained results showed that marsh frogs from Lake Krupac have a higher growth rate than those from Lake Slano.
Records of Body Bending Behavior (‘Liana Crypsis’) in Five Snake Species in Thailand and One in Spain
Authors: Hauser Sjon , Smits Ton , Van Rooijen Johan
Published: May 2022

Hitherto, body bending behavior (BBB) has been reported for less than a dozen of different snake species from tropical and subtropical America. Most authors assume that this rarely documented behavior is cryptic and antipredator, e.g., by taking the form of a liana the snake may avoid being attacked by a potential predator. We herein report the first records of this behavior in snakes in Asia and Europe. A dozen cases of body bending are documented for the colubrids Coelognathus radiatus (Boie, 1827), Ptyas carinata (Günther, 1858) and Oligodon joynsoni (Smith, 1917), and Malpolon monspessulanus (Hermann, 1804), and the natricids Fowlea piscator (Schneider, 1799) and Rhabdophis siamensis (Mell, 1931). In addition to the earlier reports from the New World, we suggest that BBB is widespread in snakes throughout the tropical and subtropical world. For a number of species that display it relatively frequently, such as C. radiatus in Thailand, BBB may have a significant adaptive value. We propose that this behavior is basically a kind of defensive immobility response that may develop swiftly or rather slowly and which is most often associated with diurnal activity, open spaces and an inclination to aggressive defenses. Our data suggest that its function is more often aposematic than cryptic.
