A árvore Delonix regia (flamboyant) pertence à família Fabaceae, subfamília Caesalpinioideae, originário da ilha de Madagascar. Tem potencial valor econômico ornamental, pois se trata de uma espécie extremamente florífera e exuberante, indicada para programas de arborização, como parques, praças e jardins, sendo inadequada para ruas e avenidas, devido a suas raízes serem caracterizadas como superficiais. Essa espécie exótica, adaptada as condições ambientais de clima tropical, tem porte de 10 – 12m de altura, de tronco volumoso, espesso, com raízes tabulares. Por apresentar características de dormência tegumentar, este trabalho teve objetivo de avaliar alguns tratamentos para superação de dormência das sementes do Delonix regia. O experimento foi do tipo quantitativo, em que as sementes foram submetidas a três tratamentos e uma testemunha, em um total de 4 tratamentos, com 75 sementes cada. A emergência foi observada in locu, por meio de contagem manual. Os tratamentos utilizados foram: escarificação mecânica com lixa (n° 120); imersão em água em temperatura ambiente por 72 horas, choque térmico com imersão das sementes em água a 80 ºC por 05 min e a testemunha em que não houve nenhuma intervenção. Observou-se que a escarificação mecânica e o choque térmico proporcionaram os melhores resultados para superação de dormência das sementes do Delonix regia.Palavras-chave: Paisagismo. Dormência. Emergência.AbstractThe tree Delonix regia (flamboyant) belongs to the family Fabaceae, subfamily Caesalpinioideae, originally from the island of Madagascar. It has the potential ornamental economic value, because it is an extremely floriferous and exuberant species suitable for reforestations programs such as parks,and gardens, being inappropriate for streets and avenues, because its roots are characterized as superficial. This exotic species, adapted to the environmental conditions of tropical climate, reaches size of 10-12 m tall, large trunk, dense with tabular roots. It is renowned for being an extremely floriferous and exuberant species. By presenting cutaneous numbness characteristics, the objective of this study was to evaluate some treatments to overcome dormancy of seeds Delonix regia. The experiment was the quantitative type, in which the seeds were subjectedto three treatments and a control, a total of 4 treatments with 75 seeds each. The emergence was observed in locus through manual counting. The treatments were mechanical scarification with sandpaper (#120); immersion in ambient temperature water for 72 hours, thermal shock deep soaking the seeds in water at 80 °C for 5 minutes and the control, which had no intervention. It was observed that the mechanical scarification and thermal shock provided the best results for breaking dormancy of seeds Delonix regia.Keywords: Landscaping. Emergency Seedling. Dormancy

Bat flies were surveyed between March, 2007 and February, 2008, in the Carnijó Private Natural Heritage Reserve (08° 07′ S and 35° 05′ W), an area of Atlantic Rainforest in the municipality of Moreno, in the Brazilian state of Pernambuco. Bats were captured biweekly using mist nets set during six hours each night. The ectoparasites were collected with tweezers and/or a brush wet in ethanol and stored in 70% ethanol. The specimens are deposited in the zoological reference collection of the Federal University of Mato Grosso do Sul. Sixteen species of streblid bat flies were collected from 10 bat species of the family Phyllostomidae. Thirteen of the these streblid species were recorded for the first time in Pernambuco.

Coleoptera of the family Geotrupidae play an important ecological role in the decomposition of animal and plant organic matter. In Brazil there is little information on the diversity and distribution of this group, thus, this work had a purpose to study Geotrupidae species, occurring in Aquidauana, MS. A survey for geotrupids was conducted in Aquidauana, Mato Grosso do Sul, Brazil. Beetles were captured using a light trap over a period of two years, from January 2006 to December 2007. A total of 907 specimens were collected and identified to eight species. From the subfamily Bolboceratinae, the species identified were Bolbapium minutum (Luederwaldt, 1929) and Pereirabolbus castaneus (Klug, 1845). In the subfamily Athyreinae the species identified were Athyreus bilobus Howden & Martínez, 1978, Parathyreus aff. bahiae, Neoathyreus aff. julietae, N. sexdentatus Laporte, 1840, N. centromaculatus (Felsche, 1909) and N. goyasensis (Boucomont, 1902). Four species (A. bilobus, N. centromaculatus, N. goyasensis and P. castaneus) are reported for the first time in Aquidauana, MS, Brazil. The most abundant species, representing 85.9% of the total capture, was B. minutum. The greatest numbers of specimens was caught from October to December of both years of the study.

The coccidian Caryospora bigenetica was first described in the snake Crotalus horridus (Viperidae) from United States of America. This study represents the first record of the occurrence of C. bigenetica in snakes in South America. Feces were sampled between November 2013 and May 2014 from 256 wild snakes maintained in scientific breeding facilities in the states of Mato Grosso do Sul (MS; n = 214) and Rio de Janeiro (RJ; n = 42), Brazil. Caryospora bigenetica was found in 14 (5.6%) snakes, all belonging to the family Viperidae. Ten Bothrops moojeni and two Crotalus durissus from MS were infected. The coccidian was also found in one C. durissus and in one Bothrops jararacussu from the state of RJ. The oocysts were spherical with a double wall, the exterior lightly mammillated, striations apparent in transverse view, 13.0 µm (12 – 14); polar granule fixed in the internal wall. Sporocysts oval or pyriform, 10.0 × 8.0 µm (9 – 11 × 8 – 9); Stieda body discoid; sub-Stieda body present; sporocyst residuum present, formed by a group of spheroid bodies between sporozoites. This study increases the number of viperid hosts of C. bigenetica and expands the geographical distribution to South America.

Tegalharjo village is a village in Glenmore sub-district, Banyuwangi district, which has a very large plantation area with a variety of plants. One of the plants that thrives on plantations and people's homes is the cassava tree. But the use of cassava as a village's potential to improve the economy of citizens is less than optimal. Cassava is generally left to rot in the trees, sometimes sold cheaply with a maximum price of Rp 3.000.00 a kilo gram and even ironically it is only used as animal feed. Meanwhile the majority of housewives only depend on the family economy for their husbands' work as farmers, farm laborers, very few who are self-employed and plantation labour majority. Seeing this, there needs to be innovations that can increase the economic value of cassava. One of them by processing cassava into brownies. After being processed into brownies, the selling value automatically increases from a kilo of Rp 3.000,00 to Rp 10,000.00 in a package. This innovation was carried out by the service team through mentoring activities and training in making Brownies of Cassava.

The inconsistency of law enforcement in implementing the substance of the narcotics law has led to a polemic in the community, especially against cases of drug abuse committed by minors, it becomes unclear, the approach method used in this study uses a normative juridical approach. The research found that children as perpetrators of narcotics crimes, if they are not proven to be dealers, which can be dangerous as a basis for imprisonment for children, it is necessary to be rehabilitated as regulated in the narcotics law. Considering that children who are perpetrators of narcotics crimes are only users and are affected by bad environmental conditions both in the family and the environment. Narcotics in the Islamic perspective is analogous to the prohibition of drinking alcohol. This prohibition is carried out because narcotics cause hatred, hostility, disaster and dangerous disasters, both for users, families, communities and the nation and state. Narcotics are prohibited in Islamic law and producers, dealers and users will be subject to Had or Ta’zir sanctions.

The number of women in Ngembat sub-village is quite large, both from adolescence to the elderly, but most of them are only housewives who are not economically productive. Everything depends on the husband who works as a farm laborer and builder. Women in Ngembat sub-village have a lot of free time that can be used for productive activities. The ecoprint training held during the Community Outreach Program (COP) is the development of DKV 4 courses that implement creative-sociopreneurship learning. This subject emphasizes the aspects of entrepreneurship in the field of creative industries by utilizing local strengths. Natural resources that exist around Ngembat sub-village can be utilized as products of economic value. Abundant teak leaves due to the vast size of teak forests can be a source of income for women on the sidelines of carrying out their domestic duties in the household. Free time while waiting for children to come home from school and their husbands from work can be used to empower themselves by producing creative products and economic value. Thus, not only does women's knowledge and skills improve, but the family economy can also improve

Kajkwakhrattxi, a Northern Jê language spoken by fewer than 30 elders in Mato Grosso, Brazil, exhibits a typologically rare sound inventory, especially with respect to its series of approximants: /w, w̃, ʍ, ɽ, ɽ̃, j/, realized as a total of 17 different surface allophones: [w, w̃͡w, w̃, ʍ, ɥ, ɥ̃͡ɥ, ɥ̃, ɥ̊, ɾ, ɾ̃, ɽ, ɽ̃, ɻ, ɻ̃, ɻ̊, j, j̃]. We propose a novel reconstruction of Proto-Northern-Jê that accounts for this unusually dense inventory of approximants, namely as the result of a series of natural sound changes involving processes of lenition and assimilation. Our analysis makes use of novel fieldwork data on three underdocumented and endangered languages of the family: Kajkwakhrattxi, Panãra, and Kayapô. As a result, our reconstruction is based on a more phonetically detailed and internally coherent data set than was available to previous comparative work on Jê languages. Our results provide evidence for the possible breadth of diversity in the phonological systems of natural languages, both synchronically and diachronically, and advances our knowledge of the sound changes that occurred from Proto-Northern-Jê to its daughter languages.

Patchwork waste is an inorganic waste that is difficult to be decomposed by the environment. Patchwork waste is often a problem because many convection industries only allow patchwork waste to accumulate and then be burned and become environmental pollution because it creates smoke and gases that are not good for health. Therefore, it is necessary to reuse the patchwork waste into products that have selling power and aesthetic value. The implementation method in this service activity starts from field visits/initial observations regarding partner conditions and problems, offering solutions and program socialization, program implementation which begins with lectures on the importance of utilizing patchwork waste and demonstrations and the practice of making these products. This service activity aims to change the awareness and concern of the people of Sawah Lebar Village towards the existence of inorganic waste around the environment, especially patchwork and to equip mothers to be creative in processing patchwork waste into goods that have selling power so that they can help the family economy. The service activities that have been carried out provide education to the community around the Sawah Lebar Village, Bengkulu City, especially RT 02 about the importance of processing patchwork waste so that it becomes a product of economic value. This service activity is carried out in two stages, namely: 1. Counseling on the importance of processing patchwork waste, 2. The tutorial on processing the patchwork waste into a more useful product, namely the mask connector.
