AbstractNematodes are one of the most abundant groups of invertebrates on the face of the earth. Their extremely poor fossil record hinders our ability to assess just when members of this group invaded land and first became associated with plants. This study reports fossil nematodes from the stomatal chambers of the Early Devonian (396 mya) land plant, Aglaophyton major. These nematodes, which are tentatively assigned to the order Enoplia, are described as Palaeonema phyticum gen. n., sp. n. in the new family Palaeonematidae fam. n. Diagnostic characters of the family are: i) cuticular striations; ii) uniform, cylindrical pharynx with the terminal portion only slightly set off from the remainder; and iii) a two-portioned buccal cavity with the upper portion bearing protuberances. The presence of eggs, juveniles and adults in family clusters within the plant tissues provide the earliest evidence of an association between terrestrial plants and animals and may represent an early stage in the evolution of plant parasitism by nematodes.

In 1956 two fossil specimens were exposed in concretions associated with two crushed body chambers of the orthoconic nautiloid Rayonnoceras sp. recovered from the Fayetteville Shale (Chesterian, upper Mississippian) of northern Arkansas. The two specimens were subsequently described as a new genus and species of demosponge, Vintonia doris Nitecki and Rigby and placed in the new family Vintoniidae (Nitecki and Rigby, 1966). The specimens were described as silicified. Nitecki and Rigby's analysis, based on the presence of an assumed skeletal net resembling the spongin net of Recent sponges, suggested that the specimens were demosponges with sycon structure. The “net” was considered spongin because of its geometric pattern and cellular appearance. That interpretation led to the placement of the specimens in the Order Keratosida despite the presence of an apparently well-developed ectosomal region, a feature that is not common in the Keratosida (Nitecki and Rigby, 1966).

Camp Life

Everyone is created to live in a herd, a group of people with whom they build a community. The community may be the family home, friends, acquaintances from work, the backyard or eventhe street. We feel better when we meet other people. When modern man speaks of isolation, he thinks only of closing himself off at home, peace and quiet, lack of contact with his family or going off into the unknown. He does not think of the forced isolation that prevailed among people in wartime. It determined everyday life, changed people’s values and dehumanised them. The worst was the camp isolation, which took people by surprise. No one expected that someone could deprive people of their lives, away from family and friends. Isolation can be divided into sectors: internal and external. With time it is possible to get out of it. A person’s attitude and the presence of other helpful people can help. People in the camp escaped isolation in different ways. The longing for love, the touch of another human being, tenderness and a smile had different faces. One of the themes of camp life was children going to slaughter. They did not realise that they would disappear from the face of the earth together with their parents. Smiling, carefree children were not afraid of anything, they felt no fear or exclusion. International cooperation was the order of the day in many camps. Although the women did not know the language, they used gestures, similar expressions. Each of the women prisoners sensed their fate and therefore needed each other’s help. No matter what country the prisoners came from, no matter what part of Europe, they all fought to survive. For many of them the camp became a home, where relationships proved beneficial. The escape from camp “happiness” was all-day work outside the camp. Prisoners would go out on purpose to do hard work in the fi elds, digging pits, in order not to see what was going on in the camp. The variety of isolation is beyond comparison. It is possible to live in isolation, to have contact with others, but to be well aware that one day normality will return. The people in the camp also had hope, but they knew that this hope could end rather quickly for them — in the crematorium.

Traditionally in Africa, there is reciprocal dependency between parents and children. While children depend on their parents in meeting their needs at early stage in life, parents on the other hand, rely on their children for care and support later in life. This exchange of roles underscores the characteristic intergenerational reciprocal obligations obtainable in within the family. This paper is an assessment of how prevailing socio-economic conditions in Nigeria have impacted children’s caregiving obligation to parents in the face of government insensitivity on the welfare of the elderly. It advocates a synergy between informal and formal support systems to ensure adequate social and economic support for a meaningful ageng process in Nigeria.

Early Land

When Hodgson (1964) proposed the new family Phyllothalliaceae together with the initially monotypic genus Phyllothallia Hodgson (1964: 247) based on Phyllothallia nivicola Hodgson (1964: 247), she mentioned “This new family is not a splinter entity from any already recognized family, but is originated to contain a genus which in vegetative characters at least is completely different from any known genus. The characters of the family are those of the genus”. The first sentence specifies the features in which Phyllothalliaceae is different from the other families but not how these features differ and so it does not satisfy the requirement of Art. 38.1(a) for a description/diagnosis (see: Art. 38. 2. Ex. 4). Although Grolle (1972: 216) discussed the validity of the family and considered the second sentence fulfil the requirements for the valid publication, ICN (McNeill et al. 2012) allows a single description/diagnosis for monotypic genus and species only. Hence, the family Phyllothalliaceae lacked a description/diagnosis which was needed when proposed and it has never been validly published until now. In order to be able to use the name in the forthcoming world checklist of Hornworts and Liverworts (Söderström et al., in prep.), the family is validated here. Note that a Latin description is no longer needed under the current ICN (McNeill et al. 2012).

The Family

Two new distinctive families, Crassimarginatidae and Scoliostomatidae, each characterized by unusual gerontic apertural morphotypes, are established on the basis of study of the richly diverse Lower Devonian gastropod fauna of the Road River Formation in the Royal Creek area, Yukon Territory. The Early Devonian genus Crassimarginata Jhaveri, 1969, is transferred from the family Palaeotrochidae and placed, together with the new genus Yukonoconcha, into the new family Crassimarginatidae, which is characterized by a pupiform shell with an explanate outer apertural lip in the gerontic growth stage. The new family Scoliostomatidae unites Devonian gastropod genera (Scoliostoma Braun, 1838; Brilonella Kayser, 1873; Anarconcha Horný, 1964; Eoscoliostoma new genus; Mitchellia Koninck, 1877; and Pseudomitchellia new genus), which are characterized by a distinctive, free, twisted (both outwards and backwards) gerontic final half whorl. More detailed morphological comparison of members of this family has allowed their division into two new subfamilies: the Scoliostomatinae and Mitchelliinae. New genera include Yukonoconcha, Eoscoliostoma, and Pseudomitchellia. The former two genera are represented each by a single new species from Yukon Territory, Yukonoconcha pedderi and Eoscoliostoma norrisi. The latter genus is represented by two species, the type Pseudomitchellia bohemica (Perner) from the Koněprusy Limestone (Pragian) of the Czech Republic and Pseudomitchellia macqueeni new species from Yukon Territory.

Abstract Background and Aims Structurally preserved arbuscular mycorrhizas from the Lower Devonian Rhynie chert represent core fossil evidence of the evolutionary history of mycorrhizal systems. Moreover, Rhynie chert fossils of glomeromycotan propagules suggest that this lineage of arbuscular fungi was morphologically diverse by the Early Devonian; however, only a small fraction of this diversity has been formally described and critically evaluated. Methods Thin sections, previously prepared by grinding wafers of chert from the Rhynie beds, were studied by transmitted light microscopy. Fossils corresponding to the description of Archaeospora spp. occurred in 29 slides, and were measured, photographed and compared with modern-day species in that genus. Key Results Sessile propagules <85 µm in diameter, some still attached to a sporiferous saccule, were found in early land plant axes and the chert matrix; they developed, in a similar manner to extant Archaeospora, laterally or centrally within the saccule neck. Microscopic examination and comparison with extant fungi showed that, morphologically, the fossils share the characters used to circumscribe the genus Archaeospora (Glomeromycota; Archaeosporales; Archaeosporaceae). Conclusions The fossils can be assigned with confidence to the extant family Archaeosporaceae, but because molecular analysis is necessary to place organisms in these taxa to present-day genera and species, they are placed in a newly proposed fossil taxon, Archaeosporites rhyniensis.

This paper seeks to elaborate on the textual interpretation of Q.S Muhammad verse 4 and Q.S at Taubah verse 5. These two verses are often employed by the extremist Muslim groups to legitimize their destructive acts carried out on groups considered as being infidels and as such lawfully killed. The interpretation was conducted using the double movement hermeneutics methodology offered by Fazlur Rahman. After reinterpretation, the two verses contain moral values, namely the war ordered by God must be reactive, fulfill the ethics of "violence" and be the last solution. Broadly speaking, the warfare commanded in the Qur'an aims to establish a benefit for humanity on the face of the earth by eliminating every crime that exists. These two verses in the contemporary socio-historical context in Indonesia can be implemented as a basis for combating the issue of hoaxes and destructive acts of extremist Muslim groups. Because both are crimes and have negative implications for the people good and even able to threaten the unity of mankind.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

The Face

Facial expression is one of some aspects that can deliver story and character’s emotion in 3D animation. To achieve that, we need to plan the character facial from very beginning of the production. At early stage, the character designer need to think about the expression after theu done the character design. Rigger need to create a flexible rigging to achieve the design. Animator can get the clear picture how they animate the facial. Facial Action Coding System (FACS) that originally developed by Carl-Herman Hjortsjo and adopted by Paul Ekman and Wallace V. can be used to identify emotion in a person generally. This paper is going to explain how the Writer use FACS to help designing the facial expression in 3D characters. FACS will be used to determine the basic characteristic of basic shapes of the face when show emotions, while compare with actual face reference. Keywords: animation, facial expression, non-dialog
