Abstract Rapid learning in the young of most endothermic animals can be expected to be favoured by natural selection because early independence reduces the period of vulnerability. Cases of comparatively slow juvenile development continue, therefore, to attract scientific attention. In most species of birds, including raptors, the young depend on their parents for some time after fledging for the provisioning of food and for protection whilst they learn to become nutritionally and otherwise independent. Among raptors, post-fledging dependence periods that exceed six months are exclusive to the largest species and these have reproductive cycles that exceed 12 months. By contrast, young of the medium-sized grey falcon Falco hypoleucos have been reported in close company with their parents up to 12 months after fledging, i.e., at a time when the adults are expected to breed again. We investigated the occurrence and characteristics of prolonged adult-juvenile association relative to other falcons and similar-sized raptors. We found that the behavioural development of grey falcon young is extremely delayed, and that they even depend nutritionally on their parents for up to 12 months after fledging. We suggest that these two distinctive features are, ultimately, adaptations of the grey falcon to its extreme environment, Australia’s arid and semi-arid zone, one of the hottest environments in the world.

ABSTRACTA number of studies show that climatic shocks have significant economic impacts in several regions of the world, especially in, but not limited to, developing economies. In this paper we focus on a drought-related indicator of well-being and emergency spending in the Brazilian semi-arid zone – rainfed corn market – and estimate aggregate behavioral and forecast models for this market conditional on local climate determinants. We find encouraging evidence that our approach can help policy makers buy time to help them prepare for drought mitigating actions. The analysis is applicable to economies elsewhere in the world and climatic impacts other than those caused by droughts.

Extract Information

The present study was carried out in three districts viz; Rewari, Sirsa and Hisar of Haryana state. A survey of 60 sampled farms was conducted to extract information pertaining to various expenses incurred in cultivation of castor and output attained as well as to ascertain the perception of farmers for various problems encountered in production and marketing of castor seed. The descriptive analysis was employed to draw valid inferences from the study. The results revealed that net profit accrued from cultivation of castor seed was ₹ 46331 ha -1 in the study area. The value of B: C ratio of castor cultivation was more than one and also higher as compared to prevalent cropping systems indicated that cultivation of castor seed is economical viable entity. However, production constraints like retention of F2 seed in the field over year, grain scattering, shortage of irrigation water, frost effect on crop yield and marketing constraints like absence of MSP, higher transportation cost sale of castor seed in distant markets, frequent fluctuation in market price, non-availability of processing units were observed.

Background: Many antibiotics were widely used as medication based on their distinctive features. Among them, sulphonamides were commonly used, however their recalcitrant nature makes them difficult to dispose. Hence, their interaction with environment and analytic technique requires considerable attention globally. Objective: Therefore, this review aimed to provide detailed discussion about environmental as well as human health behaviour and analytic techniques corresponding to sulphonamides. Methods: Various results and discussion were extracted from technical journals and books published by different researchers from all over the world. The cited bibliographic references were intentionally investigated in order to extract relevant information related to proposed work. Results: In this review, the determination techniques such as UV-spectroscopy, Enthalpimetry, Immunosensor, Chromatography, Chemiluminescence, Photoinduced fluorometric determination, Capillary electrophoresis for sulphonamide determination were discussed in detail. Among them, High performance liquid chromatography (HPLC) and UV-spectroscopy was effective and extensively used for screening sulphonamide. Conclusion: Knowing the quantification and behaviour of sulphonamide in aqueous solution is mandatory to opt the suitable wastewater treatment required. Hence, choosing appropriate high precision and feasible screening techniques is necessary, which can be attained with this review.

Aim: Quinoa is a popular source of protein, minerals and alternative to traditional grains. The objective of this study is to introduce the Quinoa in the semi-arid zone of Sindh province of Pakistan. Method: A variety of NARC-9 from the agricultural Punjab province was cultivated and subjected to analyze the growth, morphological characters of the varieties obtained, saponin, protein and the elemental composition viz. Cd, Cu, Fe, K, Na, Pb, and Zn. Result: The result demonstrated the optimum growth and no disease were found in the experimental area. At least three major varieties of quinoa were obtained. Seed morphological data of these three quinoa cultivars were collected. The average saponin levels were quite reasonable. Overall proteins band pattern revealed very high polymorphism in quinoa cultivars and the results were also in good agreement with earlier studies. Conclusion: All quinoa cultivars of Madinat al-Hikmah showed high concentrations of albumin than globulin concentrations (i.e. 48-52% and 24-27%, respectively) as compared to control seeds from market that had similar concentrations of the two fractions i.e. 35.58% and 37.68%, respectively. Likewise, low concentrations of prolamin 14-16% and glutelin 11-12% compared to control seeds 13% rank our crop much better quality than the imported one in the market. The trend of elemental accumulation was followed as K >Na >Fe >Zn >Cu >Pb >Cd, while for comparison it was Na >K >Zn >Fe >Cu >Pb >Cd >Pb for wheat grown under similar conditions. Traditional grains together make a major contribution to the total nutritional element intake of the average Pakistani citizen through diet, not only because of large amounts consumed, but also in part by suitable levels of their proteins and elemental up take for good health. Thus the successful cultivation of quinoa in the semi-arid zone of Sindh will certainly prove beneficial.

In popular imagery, the littorals of Sulu and Zamboanga conjure visions of pirates, terrorists, and bandits marauding its rough seas, open shores, and rugged mountains. These bleak accounts render the region nothing but a violent and peripheral southern Philippine backdoor inconspicuous to the sophisticated constituencies of the world’s metropolitan centres. Obscured from these imageries are the lasting cosmopolitan traits of openness, flexibility, and reception of local folk to trans-local cultural streams that marked Sulu and Zamboanga as a globalised space across the ages and oceans. The distinctive features of these cosmopolitan sensibilities are strikingly discernible in inter-generationally shared narratives, artefacts, and performances that were continually renewed from the days when Sulu and Zamboanga served as a borderless trading and cultural enclave nestled at the crossroads of the Pacific and the Indian Oceans. These enduring cosmopolitan sensibilities are embodied in the blending, among others, of the time-honoured dance of pangalay and the pop-musical dance genre celebrated on actual, analogue, and digitally-mediated spaces of the contemporary world. Furthermore, these embodied sensibilities are evident in song compositions that proclaim the humanistic themes of hope, peace, and prosperity to their place and the world in ways that exemplify the local people’s broader sense of connections beyond the narrow association of family, community, ethnicity, religion, and identity. This mixed bag of age-old and recent imaginaries and cultural traffic evoke a sociality that link the social spaces of the troubled but once and current globalised region to continuing acts of transcendence in history, memory, and visions of the future. In these marginalized places, we can see an unyielding tradition of cultural re-adaptation and creativity made up of myriad everyday acts that are down-to-earth, pragmatic, interstitial, and practical cosmopolitanism.

In Article 8 ECHR privacy right jurisprudence, photographs are deemed distinct forms of information that are particularly intrusive in nature. This article is concerned with explaining why this is so. Part 1 examines the notion of ‘intrusion’ itself. It argues that ‘intrusion’ functions as a legal metaphor and plays an important role in constructing a binary between an outer self presented to the world and a ‘spiritual’, emotional interior that privacy purports to protect from transgression. Part 2 argues that this ‘spiritual intrusion’ metaphor is influential in the continental personality right that informs the ECtHR’s approach to Article 8 protection for photographed individuals. This leads to potentially stronger protection for image, including a basic Article 8 right to control one’s image. Yet there is a divergence of approach in the English courts, where personality theory has limited influence; here there is traditional scepticism towards an image right and photographic capture is largely neglected. Part 3 argues that photography becomes a relevant factor at publication stage, where courts agree that the distinctive features of the medium may cause or exacerbate intrusion. This is because photography creates a permanent, infinitely replicable ‘truthful’ record of the individual’s image that can be disseminated to the objectifying gaze of a mass audience. But the medium also leads viewers to overlook its inherent complexities and ambiguities. Ultimately, Article 8 jurisprudence, particularly in the ECtHR, occasionally adopts reasoning that contains echoes of the ‘photographs steal souls’ mythology.

Development in the spa industry is going through difficulties caused by the world situation of tourism recovery. In days of compliance with anti-epidemic measures and social distance, the restoration of the spa offer will be based on innovative solutions for diversity in the spa services and products. This is the challenge of more enterprising and resourceful professionals in business to avoid the struggle for survival. One of their main fulcrums is reorientation towards non-price competition, which is based on the distinctive features of the product. Either it consists of innovative product design or mere market segmentation, product differentiation typically involves externalities across competitors, which clearly play an important role in firm's competitive incentives to invest in differentiation. The purpose of this report is through research and analysis of supply and development in spas, to prove the hypothesis that the diversity of spa products and services is fundamental to recovering in a highly competitive and further financially aggravated, current environment in tourism.
