The aim of this study was to evaluate interrelationships of body weight and bone weight and densitometric properties of the tibiotarsus in White Koluda Geese (W31) in the post-hatching period. The study was performed using dual-energy X-ray absorptiometry (DEXA) and peripheral quantitative computed tomography (pQCT) at two different parts of tibia: proximal metaphysis and mid-diaphysis. The investigation was performed on 100 bones obtained from males and females at the age of 1, 14, 28, 42 and 56 days of life. All the calculations were performed using the Statistica 9.0 software (StatSoft, Inc. Tulsa, USA). Pearson’s correlation coefficient of body weight and bone weight with all the investigated variables of bone was determined. Depending on the method used for densitometric measurements – DEXA or pQCT, the current study has revealed significant differences in the number of correlations of bone weight and body weight with the evaluated densitometric parameters. Sex-related differences in the investigated interrelationships were also found. In the case of proximal epiphysis, negative correlations of vBMD, tBMC, CTR_DEN and CRT_CNT with body weight and bone weight dominated in one-day-old males. Based on the current observations and the negative correlations of body weight and vBMD, CRT_DEN and TRAB_DEN obtained in the mid-diaphysis of tibiotarsus at the age of 14 days of life, it was concluded that this bone is much more prone to deformations and fractures in males than in females.

Indian society changed after digitalization and economical reformation. Currently, the Facebook is the most popular social media in India. The political cartoonist took that platform as an opportunity to share their thoughts and raise socio-political issues through their cartoons. The aim of the paper is to study responses (likingness and affective) to political cartoons in respect to responsiveness towards cartoons, gender, and socio-economic status. The study was conducted among 875 Indians from different parts of India including males and females with various socio-economic backgrounds. The data captured in the form of sentiments (love, sadness, angry and happiness emotions) for each cartoon shared in the Facebook timeline. Then, relevant descriptive statistics were computed using IBM SPSS 20.0 software. Results showed that maximum Facebook users expressed their thoughts about political cartoons through emoticons in terms of like, sad, angry, and happiness. It is found that male user are more likely to be expressive to political cartoons than female user. Mostly user from low and middle socio-economic backgrounds relate themselves with the cartoon scenarios and shown interest than users from higher class of the society. Hence, political socio-political scenarios can be communicated effectively using political cartoons in Facebook as the people of India are relating themselves with various cartoons.

Background: The topographic and morphometric anatomy of various foramina provides an easy approach in performing nerve blocks by their proper tracking for regional anesthesia in surgical interventions. There is no previously reported information on the applied anatomy and clinical significance of the maxillofacial and mandibular regions of the Indian mithun. The present study was designed to provide important clinical landmarks related to tracking of the infraorbital, mental and mandibular nerves with its clinical significance in regional anesthesia in mithun. Methods: The study was conducted on the maxillofacial and mandibular regions of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland state of India and processed as per the standard maceration technique. Altogether, a total of twelve measurements were taken in the maxillofacial and mandibular regions of mithun by using a digital vernier caliper and the results were expressed as mean±standard deviation. The obtained parameters from the present study can be useful for an extraoral and intraoral approach for nerve block of the infraorbital, mental and mandibular nerve in the maxillofacial and mandibular regions of mithun. Result: The present study revealed that all the obtained parameters related to regional anesthesia showed a significant statistical difference (P less than 0.01** and P less than 0.05*) between the males and females of mithun. It can be concluded from the present study that the various applied parameters of the present study will aid the clinicians in the implication of regional anesthesia in the head region of mithun.

Background: In scapula, the acromion process projects forwards almost at right angle from the lateral end of spine. Morphometry of the acromion process is an important factor in contributing to impingement syndrome of the shoulder joint.Methods: The study was performed at Department of Anatomy, PGIMS Rohtak on 50 pairs of human scapula, out of which 30 were males and 20 were females. The various parameters like length, width, thickness, coraco-acromial distance, acromio-glenoid distance and types of acromion process were recorded using vernier calipers. These parameters were compared in both sexes on both the sides.Results: Type-II Acromion i.e. Curved type was found to be most predominant. Statistically significant difference was noted in all the five parameters between males and females except Acromio-glenoid distance on right side.Conclusions: Knowledge of the morphometric parameters of acromion process is important for Orthopaedicians, Anthropologists and Anatomists.

SUMMARY Fiddler crabs inhabit intertidal sand- and mudflats, where they live in dense colonies and are active on the surface during low tide. They exhibit a rich behavioural repertoire, with frequent interactions between animals in the context of territorial and mating activities. Male fiddler crabs have one massively enlarged and conspicuously coloured claw, which they use in waving displays and in fights with other males. The crabs carry their eyes on long, vertically oriented stalks high above the body and, as a consequence, see the bodies of conspecifics in the ventral visual field, below the local visual horizon, and against the mudflat surface as background. We filmed events in a colony of Uca vomeris with a normal video camera and an ultraviolet-sensitive camera placed at the eye height of an average crab, approximately 2–3cm above ground. We also used a spectrographic imager and linear polarized filters to analyse the cues potentially available to the animals for detecting, monitoring and possibly identifying each other. Areas of high contrast in mudflat scenes include specular reflections on the wet cuticle of crabs that are horizontally polarised. Besides specular reflections, some parts of the cuticle generate high-contrast signals against the mudflat background, both at wavelengths between 400 and 700nm, and in the ultraviolet region between 300 and 400nm. Uca vomeris can be very colourful: the different parts of the large claw of the male are white, orange or red. The carapace colours of both males and females can range from a mottled yellowish green brown, to a brilliant light blue. White and blue colours contrast starkly with the mudflat background, especially in the ultraviolet wavelengths. Under stress, the blue and white colours can change within minutes to a duller and darker blue or to a dull white.

Skull Bones

Background: There is scanty information on the morphometry of the skull of Indian mithun; therefore, the present study was designed to provide morphometric data of the skull of Indian mithun. Methods: The study was conducted on the skull bones of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland states of India from September, 2019 to March, 2020. In the present study, altogether, a total of forty-five parameters were taken in the skull bones of males and females of Indian mithun. Result: The biometrical observations on the different parameters of the skull of Indian mithun were found to be significantly (P less than 0.01, P less than 0.05) higher in the males than females. The measurements demonstrated that the skull of the mithun was elongated and dolichocephalic as per the value of the skull index. The skull index/ cephalic index was 48.76±0.03 in males and 48.71±0.02 in females of the mithun. The length, width of the skull was 44.52±0.02, 44.41±0.02 in males and 21.62±0.04, 21.57±0.05 in females of mithun, respectively. The orbital margin was circular and complete in mithun. The cranial cavity of mithun was oval in outline with a capacity of 530.00±0.27 cm3 in males and 523.00±0.31 cm3 in females. The foramen magnum was large, roughly oval with a foramen index as 96.93±0.06 in males and 97.19±0.04 in females. The present morphometrical studies on the skull of mithun can be useful to the wildlife professionals and zoo veterinarians for the determination of sex of this animal and distinguish from other domestic and wild animals for solving veterolegal cases.

Data for analysis of age-related changes in growth in the intercanthal (en–en) and biocular (ex–ex) widths were obtained from 1,594 healthy North American Caucasians in age groups from 1 to 18 years, divided equally between males and females. At 1 year, the degree of development of the intercanthal width reached 84.1%, and that of the biocular width 85.9% of adults in both sexes. The levels of growth achieved by 5 years of age rose to 93.3% in the intercanthal width and 88.1% in the biocular width, in both sexes. The average total growth increments achieved between ages 1 and 18 years were 5.2 mm in the intercanthal width and 12.5 mm in the biocular. The intercanthal width showed very little growth after 1 year of age; in contrast, the biocular width showed significantly greater growth increments both before and after 5 years of age. Rapid growth was observed between 3 and 4 years in the intercanthal width of both sexes. The age-related growth observed in the biocular width was small but continuous up to maturation time. The intercanthal width reached full maturation at 8 years in females and 11 years in males, and the biocular width at 13 years in females and 15 years in males.
