Abstract. Piglets establish a relatively stable teat order after the first week of lactation, when each piglet chooses a preferred teat or teat pair where they tend to suckle permanently. The mechanism underlying the choice that leads each piglet to the same suckling position is still not clarified. In the present case study, piglets with different preferred suckling positions (anterior, posterior) were transferred to a foster sow after completion of the regular 4 weeks of lactation by their biological mother. For both sows, which were identical based on parity, litter size and farrowing date, we examined the suckling positions of the experimental piglets. Piglets occupied exactly the same suckling positions on both sows. Thus, piglets precisely track positions on the mammary complex of a sows udder even when previously learned discriminable stimuli have been changed, such as odours, tastes, morphologies (of sows udder or the sow itself), vocalizations, and neighbouring littermates. Our observation indicates that the spatial configuration of the mammary complex, which is determined by two parallel rows of teats arranged in pairs, can hypothetically be proposed as an important cue for piglet suckling orientation. Therefore, additional attention should be given to the exact spatial position of piglets (and vacant positions) on the mammary complex of biological and foster mothers in order to reduce stress from cross-fostering, which is standard practice in contemporary piglet production.

Present Case Study

Twin studies have mostly focused on the pattern of maladaptive behaviour manifested by the twins and their biological basis but the findings have remained controversial till date. The present case study explores the psychopathology in 14 year old twins of Indian origin. They were referred for psychometric assessment and psychotherapy for their conduct problems. The tools administered on them during psychometric assessment are Wechsler Intelligence Scale for Children IV (WISC-IV), Rorschach Inkblot Test (RIBT) and Thematic Apperception Test (TAT). Findings are discussed in terms of the personality processes and relationship quality of the twins.

Present Case Study

In the last decades, geophysical methods such as magnetic survey have become a common technique for prospecting archaeological sites. At sub-Saharan archaeological sites, however, magnetic survey and correlated techniques never came into broad use and there are no signs for an immediate change of this situation. This paper examines the magnetic survey undertaken on the Nigerian site of Zilum, a settlement of the Gajiganna Culture (ca 1800-400 BC) located in the Chad Basin and dated to ca 600-400 BC. By means of the present case study, we demonstrate the significance of this particular type of investigation in yielding complementary data for understanding the character of prehistoric settlements. In conclusion, we point out that geophysical methods should play a more important role in modern archaeological field research, as they furnish a class of documentation not achievable by traditional survey and excavation methods, thus creating new perspectives for interpreting the past of African societies.

The anarchic hand syndrome refers to an inability to control the movements of one’s own hand, which acts as if it has a will of its own. The symptoms may differ depending on whether the brain lesion is anterior, posterior, callosal or subcortical, but the relative classifications are not conclusive. This study investigates the role of white matter disconnections in a patient whose symptoms are inconsistent with the mapping of the lesion site. A repeated neuropsychological investigation was associated with a review of the literature on the topic to identify the frequency of various different symptoms relating to this syndrome. Furthermore, an analysis of the neuroimaging regarding structural connectivity allowed us to investigate the grey matter lesions and white matter disconnections. The results indicated that some of the patient’s symptoms were associated with structures that, although not directly damaged, were dysfunctional due to a disconnection in their networks. This suggests that the anarchic hand may be considered as a disconnection syndrome involving the integration of multiple antero-posterior, insular and interhemispheric networks. In order to comprehend this rare syndrome better, the clinical and neuroimaging data need to be integrated with the clinical reports available in the literature on this topic.

Indoor Wayfinding

Landmarks are ideal wayfinding tools to guide a person from A to B as they allow fast reasoning and efficient communication. However, very few path-finding algorithms start from the availability of landmarks to generate a path. In this paper, which focuses on indoor wayfinding, a landmark-based path-finding algorithm is presented in which the endpoint partition is proposed as spatial model of the environment. In this model, the indoor environment is divided into convex sub-shapes, called e-spaces, that are stable with respect to the visual information provided by a person’s surroundings (e.g. walls, landmarks). The algorithm itself implements a breadth-first search on a graph in which mutually visible e-spaces suited for wayfinding are connected. The results of a case study, in which the calculated paths were compared with their corresponding shortest paths, show that the proposed algorithm is a valuable alternative for Dijkstra’s shortest path algorithm. It is able to calculate a path with a minimal amount of actions that are linked to landmarks, while the path length increase is comparable to the increase observed when applying other path algorithms that adhere to natural wayfinding behaviour. However, the practicability of the proposed algorithm is highly dependent on the availability of landmarks and on the spatial configuration of the building.

Abstract Hydrocarbons are bypassed in known fields. This is due to reservoir heterogeneities, complex lithology, and limitations of existing technology. This paper seeks to identify the scenarios of bypassed hydrocarbons, and to highlight how advances in reservoir characterization techniques have improved assessment of bypassed hydrocarbons. The present case study is an evaluation well drilled on the continental shelf, off the West African Coastline. The targeted thin-bedded reservoir sands are of Cenomanian age. Some technologies for assessing bypassed hydrocarbon include Gamma Ray Spectralog and Thin Bed Analysis. NMR is important for accurate reservoir characterization of thinly bedded reservoirs. The measured NMR porosity was 15pu, which is 42% of the actual porosity. Using the measured values gave a permeability of 5.3mD as against the actual permeability of 234mD. The novel model presented in this paper increased the porosity by 58% and the permeability by 4315%.

Shed Light

The present paper aims to highlight the physical evolution of solutions from soaking and beans cooking process. This is motivated by the desire to shed light on the particular behavior of the bean end-of-cooking solutions when they are incorporated into the soil. For that purpose, solutions from soaking were produced by putting in contact 2kg of sorted and quickly washed beans seed with 8kg of water with known physical characteristics. Concerning the solutions from cooked beans, they were produced by putting on fire the pot containing the mixture of the water from soaking and bean seeds. The beans were a variety of Phaseolus vulgaris L.,known as “Meringue”. The cooking process was done without salts. The samples of solutions were collected as follow: 30 and 60 minutes respectively after the beginning of the soaking, 30, 60, and 90 minutes after the beginning of the cooking process of the beans soaked during 60 minutes. After each sampling, the equal volume of the solution collected was replaced with the water used for the cooking process. The color of the water used for the cooking process is translucent. Concerning solutions from soaking, their coloration are gradually reddish. Solutions from soaking and cooking process became abruptly dark red. From 60 minutes of the cooking process after soaking, the dark red coloration turn to strong brown. The solution handled in the case of the present study, from soaking and cooking the beans are gradually enriched in flakes compared to the situation noticed in the water used for the cooking process. But, the enrichment becomes abruptly high with the beginning of the cooking process after the process of soaking. In terms of consequence, their physical parameters studied in the present case study all increase in the same manner, notably the mass, the volumetric mass, and the density of the different solutions. The infiltration tests made including the water used for the different processes, solutions form the end of cooking the beans, and human urine show that the infiltration rate of the water from cooked beans is very low compared to that of the water used for the processes and human urine. The total infiltration of solution of the end of cooking the bean reveals on the infiltration surface the presence of a film of a matter bearing molds, generated by the progressive settling of this solution. The correlations established between the different parameters followed up here are highly positive. But in detail, the influence of an under laid parameter, known here as temperature, has been identified as being the responsible of the questioned behavior of the parameters taken in pairs in the case of correlation studies made. Finally, from this work, it emerges that the specific behavior of the bean end-of-cooking solution when it is introduced into the soil is justified by its progressive enrichment in organic matter during the cooking process.

Skin is one of the most beautiful organs God has ever blessed to anyone. Everyone craves for beautiful skin and makes all possible efforts to make it glow. To achieve this, they are engaged in continuous use of creams, moist- urizers and other cosmetic articles which lead to immediate or long-term skin issues. Itching being the predomi- nant symptom of these cosmetic issues make people highly embarrassed in society. In Ayurveda, almost all skin conditions are explained under one umbrella called Kushta. It is broadly classified into Mahakushta and Kshudra- kushta1. Dadru Kushta one among the Kshudra Kushta is the most common skin condition accounts for 20% in all consultation in general practice2. North Karnataka is well known for its hot and humid conditions making its population at risk of many Tinea infections. Kandu, Raga and Atasi Pushpa Sankashavat Mandala are the cardi- nal features of Dadru3. In the present case study, 40 patients of Dadru Kushta were taken according to inclusion criteria. The combined effect of both Shodhana and Shamana was assessed. Keywords: Dadru Kushta, Aupasargika, Anushangi, Wilcoxon Rank Sum Test
