The paper presents the fourth part of a longer series devoted to the discussion of new Afro-Asiatic (Semito-Hamitic) etymologies. The present contribution proposes a set of new lexical roots with *f- in the Anlaut.

The long-range series “Aegyptio-Afroasiatica”is devoted to the publication of new Afro-Asiatic etymologies of Egyptian lexical roots which have been identified in the course of my research on the “Etymological Dictionary of Egyptian”(EDE, Leiden, Brill, published since 1999). The underlying consonant correspondences the proposed etymologies are based on have been elaborated and demonstrated in EDE I. The numeration of the etymological entries in the present contribution continues that of the previous parts.

During my current work on the Egyptian Etymological Word Catalogue (EEWC, ongoing since summer 1994), it has become possible to identify a great number of new lexical correspondences between Egyptian and its vast Afro-Asiatic (Semito-Hamitic) kindred. The series of papers “Aegyptio-Afroasiatica” has been started in 1995 for reporting these results. The numbering of etymological entries is continuous beginning from my very first report.

Mubi-Toram is a group of languages in the Republic of Chad (some of them close to the border with Sudan). This group belongs to the eastern subbranch of Chadic and thus represents the member of the immense Afro-Asiatic (Semito-Hamitic) macrofamily comprising six equipotential branches: Semitic, Egyptian, Berber, Cushitic, Omotic, and Chadic. Mubi-Toram is namely the last (26th) Chadic group in the classification proposed by H. Jungraithmayr (Jungraithmayr — Ibriszimow 1994, Vol. II, p. xv). This is one of the least studied Chadic groups from the standpoint of both lexicography and comparison. For each of its daughter languages we usually find just one wordlist, among them only Mubi is relatively better provided with sources.The success of modern research on Chadic phonological and lexical reconstruction (initiated by V. M. Illič-Svityč and P. Newman in the mid-1960s) fundamentally depends on how the inner reconstruction and the external (Afro-Asiatic) comparison of every single individual Chadic language group proceeds at the same time. Unfortunately, out of the 26 Chadic groups, only six (namely, Angas-Sura, Bole-Tangale, North Bauchi, Bura-Margi, Mafa-Mada, Kotoko) have been so far more or less satisfactorily studied from this viewpoint.Work on the planned comparative lexicon of the Mubi-Toram languages was begun by the author in the summer of 2008. The present series of papers is to integrate this remote lexical stock in its wider Chadic and Afro-Asiatic context by providing materials for the research outlined above.

New Afro-Asiatic parallels are suggested for Egyptian lexical roots continued from the previous communications.

The paper constitutes part of a long-range series aiming, step by step, to identify the Afro-Asiatic heritage in the etymologically little explored lexicon of Omotic (West Ethiopia), a branch displaying the least of Afro- Asiatic traits among the six branches of this ancient macrofamily.

Abstract

The efficiency of the most modern photovoltaic cells currently reaches 40–45%, which is achieved by concentrator systems. However, despite better device efficiencies concentrator photovoltaic cells have major drawback, namely the high amount of waste heat, which requires new cooling solutions.

This paper gives a short overview of the current cooling techniques and proposes a novel microchannel cooling solution for concentrator photovoltaic cells. In the concept, the microscale channels are integrated into the backside metallization of the PV device. The paper gives a description of the technological process that can be used to produce microchannels on the back of solar cells and shows the optimization of the channels to achieve optimal cooling performance.
